Small Business Person

A small business owner is the owner of a business that's considered small in terms of its work force, sales volume or organizational structure.

The term small business person includes the sole trader, proprietor, self-employed individual, and partners within a partnership.

Small businesses are privately owned corporations, partnerships, or sole proprietorships which have fewer employees and/or less annual revenue than a regular-sized business or corporation.

Initial Contact With The Inland Revenue Division

Registration - The small businessperson including the partners in a partnership and the partnership should register for the following at the Registration Unit of the Inland Revenue Division:

BIR Number (Individual)

  • Submit a copy of the Certificate of Registration from the Registrar General (if a Trade Name is registered) and a completed application form.

    An Income Tax file number and an Individual Income Tax (IIT) Account number will be assigned after the taxpayer is interviewed and provides all pertinent data. The Income Tax file number, unique to the taxpayer, will be issued to him once and should be quoted in all communications with the Inland Revenue Division. This number is also used when making payments in respect of quarterly instalment of Tax, Business Levy and Health Surcharge for the small businessperson.

BIR Number (Partnership)

  • Where the business is to be conducted as a partnership, the partnership is also required to have a BIR file number and a Green Fund Levy account, which can be obtained by submitting the completed application form, a copy of the Certificate of Registration and a list of the names, addresses and file numbers of all partners. (Each partner is required to have a BIR file number. If any of the partners does not have a file number, then the procedure for an Individual above applies.)

PAYE Number

  • If you are going to employ staff, you are also required to have a PAYE Account No. Where possible this number should be applied for at the same time as the BIR number. This number is to be used when remitting deductions made in respect of PAYE and Health Surcharge from the salary/wages of your employees. This number is different from the sole proprietor’s Board of Inland Revenue file number (this number will be preceded by the letters PYE).

    NOTE: All employees MUST have a BIR Number

    .

ALL employees MUST have a BIR Number

VAT Number

  • Where the gross annual income/sales of the business exceeds $500,000, the person must register for Value Added Tax (VAT).

    More details: Value Added Tax.

Definitions

“Total Income” means the aggregate amount of income under Section 5 of the Income Tax Act before allowing any deductions other than those under Section 10, 11, and 16 of the Income Tax (In Aid of Industry) Act.

“Allowable Deductions” means any deduction allowed in accordance with the Income Tax Act in determining a person’s chargeable income.

“Chargeable Income” means the aggregate amount of the income of any person from the sources specified in section 5, remaining after allowing the appropriate deductions and exemptions under the Income Tax Act Chapter 75:01.

“Employer” means any person paying emoluments whether on his own account or on behalf of another person to an employee, and shall be deemed to include any person paying emoluments whether on his own account or on behalf of another person, to the holder of an office. In relation to an employee or officer, “employer” means the person from whom the employee or officer receives his remuneration.

“Employee” means any person, not being the holder of an office, in receipt of emoluments.

“Emoluments” means all salary, wages, bonus, overtime, remuneration, perquisites, including value of board or lodging, stipend, commission or other amounts for services, directors fees, retiring allowances or pensions, arising or accruing in or derived from or received in Trinidad and Tobago and which are assessable to income tax, Strong>but shall not include any salary or share of profits arising from a trade, profession or vocation carried on by any person either by himself or in partnership with any other person.

“Trade” includes a business, and every trade, manufacture, adventure or concern in the nature of a trade or business.

Business Records

The Income Tax Act [Section 116(1)] requires every person engaged in any trade, business, profession or vocation to keep proper records and books of accounts, including records of annual inventory (stock).

These records must be kept-

  • in the English Language
  • at the place of business or at the residence of the proprietor
  • in T&T currency (TTD)
  • in such a form that provides necessary information that enables the Board to determine the correct tax liability.

If a proprietor finds it necessary to keep his records at a place other than his business place or residence, he must apply to the Board of Inland Revenue for prior approval. The Board will not give approval for the records and books of accounts of a business to be kept in any country other than Trinidad and Tobago.

Where a person fails to keep adequate records, the Board may require him to keep such books and accounts and records which it may specify and that person is required to comply.

Required Records for each financial Period

  1. Purchases Book

    Used to record all purchases (stock) for the business.

  2. Sales Book

    Used to record all business sales on a daily basis.

  3. Record of Expenses

    Used to record details of all business expenses (other than purchases) incurred.

    N.B. Expenses, which relate to the proprietor’s private affairs, must not be charged against the profits of the business [See Business Expenses].

    Example: If rent is paid by a proprietor for a property, which he uses both for operating a business and as his private residence, only that portion of the rent applicable to the business venture is deductible as an allowable expense for income tax purposes.

    No deduction shall be allowed from the income, in respect of rental payments incurred for the purposes of the production of income unless information relating to such payments and to the payee is furnished to the Board in a form approved by the Board. The relevant schedule on the Tax return must also be completed. Examples of other expenses that may have both private and business use include Telephone, Electricity and Motor Vehicle Operating Expenses.

  4. Stock Sheets

    An inventory of items of stock on hand may be prepared periodically during the year, but must be prepared at the end of the financial period.

    The stock on hand that has been counted should be valued on the basis of lower of cost or net realisable value.

    The method of stock valuation should be consistent, as the value of closing stock will become the figure for opening stock in the succeeding year. If the method of valuation is changed at any time during the accounting period, the Board will require both opening and closing stocks to be valued on the new basis.

  5. Wages and Salaries Book

    A record of salaries and wages paid to employees, including casual workers, must be kept. Where salary is paid in cash, the employees should certify in a salary record book or pay sheet that they received the emoluments stated. A record of Income Tax, Health Surcharge and NIS deductions must be kept.

    Employers are also required to keep on file TD1 Forms/Certificates of Approval submitted by all their employees. These should show all allowable (approved) deductions.

    Proprietor’s salary: Salary paid to a sole proprietor is not allowed as a deduction for income tax purposes. Where the proprietor of a business makes such a deduction, the amount will be added back to the net profit.

    Spouse’s salary: Salary paid to one’s spouse who is employed in the business is an allowable expense, provided that the amount paid is reasonable for the type of duty performed.

  6. Debtors and Creditors Ledgers

    Ledgers which show transactions with debtors and creditors.

  7. Assets Register

    Record of all assets owned by the business. This will show

    1. in the case of acquisitions - a description of the asset, serial number etc. and the date and cost of acquisition;
    2. in the case of disposals - the date of disposal and proceeds of disposal.

    The information in this register will be useful in computing Wear and Tear at the end of each income year.

    Where plant and machinery or a building used exclusively to house such plant and machinery is acquired on or after 1/1/95, the asset is required to be placed into one of the four classes, A, B, C, or, D in accordance with the 7th schedule and Wear and Tear is to be computed on the value of the assets in the pool at the rate applicable to that class.

    With effect from January 01, 2006 assets acquired prior to 1995 must be placed into a class specified in Schedule Seven and the relevant percentage rate must be applied to the written down value to date to determine the Wear and Tear Allowance on such assets.

    With effect from January 01, 2006 and subject to section 11B wear & tear allowance is allowed at the rate of 10 % on the reducing balance of the capital expenditure incurred in the construction of or improvement to a building/structure completed on or after 1/1/95 and used in a trade, business, profession or vocation for the production of the income.

Income

Types of Income

There are two types of income-

  1. Emolument – See “Definitions” above.
  2. Non – Emolument Income – This is derived from trade or business. It includes profits from trade/business, professional practice; royalties, rents dividends, short-term capital gains etc. See section 5 of the Income Tax Act.

The Small Businessperson is generally charged tax each year on his non-emolument income subject to the provisions of the Income Tax Act.

The person who receives both Non- Emolument and Emolument Income may be required to pay tax on both types of income.

Where the Non – Emolument income exceeds 25% of the total income, the person is required to pay quarterly instalments on such income.

The Small Business Person must include the income received from all sources on his annual income tax return.

Rents

Unless an exemption from income tax has been granted for rental income by the Minister responsible for Housing, the income from rents, premiums and other profits from the letting of property is taxable.

Where approval of the Minister responsible for housing has been granted, the exemption as to rents shall apply only where the monthly rental income in respect of-

  1. an unfurnished letting is $750 or less;
  2. an unfurnished letting, in connection with which services are provided, is $825 or less;
  3. a furnished letting is $900 or less;
  4. a furnished letting, in connection with which services are provided, is $975 or less.

The exemption with respect to the above-mentioned rents is void where the monthly rental exceeds the above-mentioned levels in any month of the year whether payable to the owner or to any other person.

Furnished Letting,” means a house rented with furniture consisting of a stove, a refrigerator, and bed and living and dining room furniture.

Service” includes any utility for which the landlord pays the supplier of that utility.

Where the income from the property is exempt under the Housing Act, a Certificate of Exemption must be submitted with each Income Tax Return filed.

The Ministry of Housing determines the validity of applications for exemption and issues the Certificate of Exemption.

Where such a certificate has been issued, the taxpayer is still entitled to deduct the related expenses even though the rent received for the property will not be brought into charge for income tax purposes.

Dividends

From 1995 dividends other than preference dividends paid by a resident company (listed and unlisted) to a resident individual are exempt from tax. Preference dividends, however, continue to be subject to the 15% tax at source. The remainder is deemed not to be income to the individual for tax purposes.

With effect from January 1, 2004 interest payable on dividend to a resident individual is exempt from tax.

Capital Gains

Any gain, which accrues on the disposal of certain assets within twelve (12) months of acquisition, is taxable and should be declared in the Income Tax Return using the relevant schedule.

Adequate records on the date of acquisition and purchase price, together with the date of disposal and selling price, should be kept.

Assets, which are chargeable to Short Term Capital Gains Tax, are all forms of property whether situated in Trinidad and Tobago or not.

These include:

  1. Options, debts and incorporeal generally;
  2. Any form of property created by the person who is disposing of it, such as goodwill, patents and copyrights;
  3. Any currency other than the currency of Trinidad and Tobago.

Assets that are exempt include:

  1. Currency other than Trinidad and Tobago currency where acquired for personal expenditure abroad by the taxpayer or his family or dependents (including expenditure on the provisions or maintenance of any residence outside Trinidad and Tobago).
  2. Sums obtained by way of compensation or damages for any wrong or injury suffered by an individual in his profession or vocation.
  3. Winnings received from betting lawfully carried on under or by virtue of the provisions of the Gambling and Betting Act, 1973 including pool betting and lotteries or games with prizes.
  4. Gains accruing on the disposal of an asset by an individual or a company, which, under the provisions of the Income Tax Act or of the Corporation Tax Act, is exempt from tax.
  5. Gains accruing on the disposal of any security in Trinidad and Tobago.
  6. Gains accruing on the disposal of –
    1. Private motor cars;
    2. (b) Household goods;
    3. Owner-occupied houses disposed of for $5,000 or under.

    In computing the Capital Gains, which can arise on the disposal of an asset, allowable deductions include:

    1. Cost price (money or money’s worth) of the asset, together with other expenses incidental to the acquisition, including legal fees, stamp duty, advertising or the amount incurred in providing the assets;

    2. Any expenditure wholly and exclusively incurred in enhancing the value of the assets, provided that such improvements are evident and effective at the time of disposal (maintenance expenses are not allowable deductions);

    3. Any expense incurred in establishing, preserving or defending his title to, or to a right over, the asset;

    4. Costs wholly and exclusively incurred on the disposal of an asset, e.g. legal fees and agent’s fees. Losses under this head should also be declared by completion of the relevant schedule of the Income Tax Return. Such losses may be set off against capital gains in the same year of income. Any excess of losses over gains is not deductible from other sources, but may be carried forward to be set off against capital gains in subsequent years.

Business Expenses

A Small Business Person is allowed business expenses as a deduction in order to calculate his chargeable profit/income. Business expenses are the expenses incurred in the production of the income of the business.

Balancing Charge/Allowance

Calculations

Whenever an asset on which “Wear and Tear” has been allowed during the course of its usage, is sold or disposed of at a price above or below the written-down value, a balancing charge or allowance, as the case may be, arises.

Effective 1/1/98 Balancing Allowances shall not be made until there are no assets left in the pool. Balancing Charges shall not be made until the value in the pool results in a credit balance.

Acquisitions

In computing Wear and Tear Allowances, the value of acquisition of plant or machinery in a year of income shall be added to the written down value of the plant and machinery in the pool.

Disposal

Where disposals are made during a year of income, the value of the plant and machinery disposed of shall be deducted from the written down value of the plant and machinery however:

  1. in the event of a sale, the amount deducted shall be the proceeds of the sale of the plant and machinery or
  2. in event of loss or destruction of plant or machinery, the amount deducted shall be the money received by way of insurance or compensation.

Private Use of Asset

Where the asset is used for both business and private purposes, the pool must be debited with the cost of the asset equivalent to its business use. Where an asset is disposed of, the pool shall be credited with the same percentage being applied to the proceeds of disposal up to the original cost of the asset.

Where assets are brought to the business from private use, the value to be applied will be the market value.

If an asset from the business is appropriated for private use, the amount (credited) deducted from the pool will be the market value.

In the case of any other event resulting in the cessation of interest in any plant/machinery, the amount to be deducted from the pool shall be the market value of the said item.

In no circumstances shall the amount credited to the pool exceed the original cost of the said Plant and Machinery.

Promotional Expenses

Effective 1/1/94 individuals involved in Trade/Business who have incurred promotional expenses which were wholly and exclusively expended in order to promote the expansion of existing foreign markets for the export of goods produced in Trinidad and Tobago and shipped in commercial quantities, are entitled to a deduction equivalent to 150% of the promotional expenses actually expended. This also applies to goods and agricultural produce manufactured or produced in T&T.

A person entitled to this deduction is not allowed another deduction under Section 10 (Profit and Loss Account) in respect of the same promotional expenses.

    • Personal Allowance
    • Approved Pension Contribution/Approved Annuity Premium
    • Alimony/Maintenance Payment

Computation Of Chargeable Profits

In calculating the chargeable profits, a small businessperson is entitled to deduct all expenses wholly and exclusively incurred in the production of that income, from his total income/sales.

All expenses claimed must be supported by proof of the expenditure such as bills, receipts and invoices. Expenses that relate to the proprietor’s private use MUST NOT be charged against the profits of the business.

Example – Calculation of Chargeable Profit

$194,000Chargeable Income/Profits As calculated by taxpayer$ 6,000<tr.$79,000

Total Income/ Sales $500,000
Less Expenses
Cost of Sales $200,000
*Proprietors Salary $72,000

Tertiary Education $ 72,000
Approved Deferred Annuity $ 50,000
*Adjustments:
Add backs: Salary to proprietor $72,000
Entertainment (25%) $7,000
Revised Chargeable Income/Profits $85,000

* This is the treatment where the proprietor deducted a salary paid to himself and also claimed 100% of entertainment expenses. N.B. Entertainment expense is limited to 75%.

Taxes

The Small Businessperson is required to pay his taxes to the Board of Inland Revenue in quarterly instalments each year. The types of taxes paid by the small businessperson are-

      • Income Tax
      • Business Levy
      • Health Surcharge
      • Green Fund Levy (Partnerships)

Late payment of all taxes will attract interest at the rate of 20% per annum from the due date to the date of payment.

Income Tax

This tax is charged on the chargeable profits of the business. It is calculated after allowing for Tax Deductions and Credit (if applicable) for the relevant income year.

The basis of calculating the estimated amount payable in the current year is:

      • apply the tax rate to the chargeable income/profits of the previous year then divide it into four.

        Previous year chargeable income/profits x rate of tax
        4

This amount is to be paid quarterly on or before –

    • March 31
    • June 30
    • September 30
    • December 31

in each year of income.

Example: Calculation of quarterly instalment (2020)

Net Profit (2019) $275,000
Less: Personal Allowance 72,000
Estimated Chargeable Income $203,000
Tax on Chargeable Income of $203,000 $203,000 x 25% $ 50,750
Estimated Quarterly tax payable $50,750 ÷ 4 $12,688

The amount of $12,688 is payable on or before March 31, June 30, September 30 and December 31, 2020.

However, where the estimated chargeable income for a year of income exceeds or is likely to exceed the chargeable income of the preceding year of income, a person shall make quarterly payments on the basis of the estimated income of the current year.

If, by the end of the fourth quarter, instalments paid are less than the tax liability disclosed in the tax return, interest shall be charged on the difference between:

  1. The tax liability on the chargeable income of the previous year of income plus 80% of the increase in the tax liability of the current year on the previous year of income; and
  2. The total amount paid by the end of the fourth quarter.

Where a taxpayer is of the opinion that his business will produce an estimated chargeable income less than the chargeable income of the previous year, he may apply to the Board of Inland Revenue for a revision of his estimated chargeable income and the amount of tax he is required to pay by quarterly instalments.

Example: Calculation of Instalment for increased chargeable profit

2018 Chargeable Profit (Previous Year) $600,000
2018 Tax on Chargeable Profit ($600,000 x 25%) $150,000
2019 Estimated Chargeable Profit (Current Year) $900,000
2019 Estimated Tax on Chargeable Profit ($900,000 x 25%) $225,000
(An Increase of $75,000)
Total Instalments to be made by December 31st 2019: (2018 tax liability + 80% of difference) = $150,000 + (80% of $75,000) $210,000

NB: The outstanding 20% of increase is due by April 30 of the next year. Interest will accrue on short payment or non-payment of tax from the due date to date of payment at the rate of 20% per annum.

Tax Payment On Both Non-Emolument And Emolument Income

An individual, who is in receipt of both non-emolument income, (such as gains or profits from the operation of a trade or business, including income from partnerships or from the practice of a profession,) and emolument income (i.e. salary, wages, pensions, etc.), is required to pay tax by quarterly instalments, where the non-emolument income is more than 25 per cent of the total income.

Example 2020

Emolument Income 12,000 x 12 $144,000
Estimated non-emolument income (Profits) $ 65,000
Estimated Total Income $209,000
Less - Personal Allowance $72,000
- Pension&NIS Contr. $10,500 (82,500)
Chargeable Income $126,500
Tax on Chargeable Income $126,500 x 25%
Total Tax Liability $ 31,625

NB: Non-emolument income is more than 25% of total income.

If we assume that the taxpayer was accurately charged to tax on his emolument income, the PAYE would be $15,375.

The quarterly installment to be paid

  • = Profit from non-emolument income x 25%
  • = $65,000 @ 25% - $16,250

Amount payable by quarterly instalments $16,250 ÷ 4 = $4,062.50

NOTE: The difference in the tax liability and the quarterly instalment would have been deducted by the employer via the PAYE System.

Business Levy

Business Levy is a tax on the gross sales/receipt of a person, other than emolument income, in excess of $360,000 effective January 2019.

Gross Sales/Receipt incorporates all income received in the ordinary course of business activities before allowing any deductions for business expenses.

The rate of Business Levy is 0.6% of the gross sales/receipts for each quarter of the current year of income.

The Business Levy is due and payable on a quarterly basis on or before:

  • March 31
  • June 30
  • September 30
  • December 31

in each year of income.

Interest on short payment of Business Levy

Where there is a short fall in payments of Business Levy, interest shall be charged on the difference between 90% of the Business Levy liability and the amount actually paid for each quarter.

For late payment of Business Levy, interest will be calculated at 20% per annum from the date following the end of the quarter when the Levy liability became due, to the date of payment.

Exemptions from Business Levy - Individuals

    • The Gross Sales or Receipts of a person which are exempt from income tax under any Act.
    • The income of a person whose emolument income exceeds 75% of his total income.
    • The Gross Sales or Receipts of a person, whose Gross Sales or Receipts in the preceding year of income do not exceed $360,000, unless there are reasonable grounds to believe that the gross sales or receipts in that particular year will exceed that sum.
    • The gross sales or receipts of the business of a person up to three (3) years from the date of commencement of business.

Computation Of Business Levy

All persons liable to make Business Levy payments are required to compute both their Income Tax and Business Levy Liabilities.

      A person is entitled to a

Tax Credit against his Business Levy Liability

      for a year of income,

of any payment made

      in respect of

Income Tax Liability

      for that year of income up to a

maximum of his Business Levy Liability

    .

To calculate the Business Levy, the Gross Sales or Receipts figures to be used are the current ones; estimation is to be used only for the last few days, (1 – 3 days) of the quarter. When an estimation is made for any period in a quarter and it is subsequently determined that the actual sales or receipts are more than the previously estimated figures, the difference of the Business Levy liability must be paid no later than the last day of the quarter following the quarter in which the estimation was made.

Partnerships

With respect to a partnership, the Individual Partner’s Share of the Gross Sales/Receipts must exceed $360,000 to be liable for Business Levy.

NB: The partners are liable to this tax, not the partnership.

Green Fund Levy

Green Fund Levy is also a tax to be paid on the gross sales/receipts of any

company/partnership

carrying on business in Trinidad and Tobago whether or not such business is exempt from Business Levy.

This rate of the Green Fund Levy tax is 0.3% of gross receipts/sales.

The Sole Trader does not pay Green Fund Levy, however the organization of the Partnership is liable to this Levy. Green Fund Levy is paid using the Partnership BIR File number.

It is due and payable to the Board of Inland Revenue on a quarterly basis on or before:

  • March 31
  • June 30
  • September 30
  • December 31

in each year of income.

In ascertaining the gross sales or receipts of a quarter an estimate of the sales for the last 1-3 days of the quarter may be required.

Where estimation is made and the actual sales of that quarter exceed the estimated figure, the short payment must be paid by the end of the quarter immediately following that quarter in which the sales or receipts were estimated.

Interest on short payments or late payments

Where a partnership, which is liable to the quarterly payment of the Green Fund Levy, pays less than 90% of its liability at the end of the quarter; interest is charged at the rate of 20% per annum on the difference between the 90% of the liability and the amount paid.

This interest shall accrue from day following the end of the quarter in which the liability occurred to the date of payment.

Overpayment of the Green Fund Levy

Where the Board of Inland Revenue is satisfied that a partnership has overpaid the levy in any quarter, the partnership is entitled to a refund of the excess tax paid.

However, instead of making a refund, the Board may otherwise choose to apply the excess tax against any future liability and notify the partnership accordingly.

NOTE:

  1. The Green Fund Levy shall be under the care and management of the Board of Inland Revenue.
  2. “Company” means an incorporated body, unincorporated association and includes a partnership. The partnership must therefore pay this levy using the partnership BIR Number.

Health Surcharge

Health Surcharge shall be charged and is payable –

  1. by every employed person who pays or is liable to pay contributions under the National Insurance Act; and,
  2. by individuals other than employed persons who are liable to furnish a return of income.

  1. individuals under the age of 16 years;
  2. persons who have attained the age of 60 years;
  3. persons whose only source of income is from pension.

The Income Tax Audit

The Income Tax Audit is conducted by the Board to verify the information submitted in an Income Tax Return.

Selection of an Income Tax Return for an Audit does not necessarily mean that the information is viewed as false or that claims will be disallowed. The Board, however, is

charged with the responsibility for collecting the correct tax payable by each taxpayer and must maintain a system to monitor taxpayer information relating to income and

expenses.

If, during the course of an audit, the auditor realizes that a taxpayer has neglected to include valid claims, this will be drawn to the taxpayer’s attention and the necessary adjustment will be made to the taxpayer’s benefit.

When his return is selected for audit, the taxpayer is informed of the date and time of the audit. Where the date and time appointed by the Board is inconvenient, the taxpayer may request a change.

An Audit may be conducted at the offices of the Inland Revenue Division or at the Taxpayer’s place of business. The Board will determine the type of audit to be conducted andinform the taxpayer of the information which must be made available to the auditor.

Objection Of Assessment

The Income Tax Act requires the Board of Inland Revenue to make an assessment on every person who is liable to tax after such a person delivers a tax return to the Board.

If a person disputes the assessment made, he may apply to the Board by a notice of objection, in writing, to review/revise the assessment, stating the grounds for such request.

The request for the objection must be done within 15 days from the date of service of the assessment in the case of residents and 45 days for non-residents.

The Board may accept a notice of objection outside of the time limit if it is satisfied that there is a reasonable excuse for making the application late.

In reconsidering the assessment, the Board has the right to request additional information from the person disputing the assessment and to inform the person in writing of the

results of its reconsideration.

If a person refuses to supply the Board with the additional information requested by the auditor, the Board may deem the original assessment to be final and conclusive.

Where the Board fails to determine an objection made within 24 months after the service of the notice of objection, the objection shall be deemed to have been determined in the favour of the person who disputed the assessment.
