The IRD's VAT registration guidance states TT$600,000 in commercial supplies in a preceding 12-month period, or supported forecasts above that amount, effective 1 January 2023. The specific treatment of supplies requires review.
Use the dedicated registration guidance
The Inland Revenue Division's VAT Application for Registration page says persons making commercial supplies of TT$600,000 or more in the preceding twelve months, or having evidence that supplies will exceed that amount in a twelve-month period, must apply. It dates that amount to 1 January 2023. A separate older self-employed explainer still refers to TT$500,000, so readers should prioritise the more specific published registration guidance and seek IRD confirmation if uncertain.
The threshold concerns commercial supplies in the relevant period, not whether the owner personally takes home TT$600,000 of profit. A business may sell TT$650,000 worth of qualifying goods but have much lower profit after stock, rent and wages. Use turnover and forecast evidence appropriate to the VAT rules when assessing registration rather than income after expenses.
Calculate the rolling twelve-month position
Make a simple monthly table of the value of relevant commercial supplies. At the end of each month, total the preceding twelve months. This can reveal a threshold crossing that would be missed if an entrepreneur started counting again every January. Businesses growing quickly should also prepare a credible forecast from contracts, confirmed orders and expected activity.
For illustration, TT$55,000 of relevant commercial supplies every month for twelve months totals TT$660,000. A seasonal business may make little in one quarter and a great deal before Christmas, so a flat monthly average can mislead. Keep invoices, sales journals and supporting contract evidence, and ask a tax practitioner to classify supplies correctly where exemption or special treatment is involved.
What happens when registration is needed?
The IRD's published guidance sets out different supporting documents for sole proprietors, companies and partnerships. Depending on the entity and application, these may include the relevant IRD forms, photo IDs and evidence of income or anticipated supplies. Documentary examples include invoices, receipts, contracts and other material that the IRD accepts as evidence of the threshold.
A VAT registration is separate from a Companies Registry certificate, BIR number or PAYE account. A newly incorporated company does not automatically have a VAT registration number. Prepare the tax registration against the correct legal entity and contact details so that invoices and bank records can later be reconciled to the registered taxpayer.
The obligations after registration
The standard rate stated by the IRD is 12.5% for applicable taxable supplies. A registered business should issue compliant tax invoices, maintain appropriate purchase and sales records and file returns for the prescribed periods. Tax collected from customers must be accounted for in a way that makes the amount owed to the Revenue Authority distinguishable from ordinary business receipts.
Budgeting matters. A merchant who receives VAT-inclusive payments should not spend the entire deposit as operating revenue. Build a VAT ledger, reconcile invoices and seek advice on input credits or exempt supplies. Correct VAT administration can be a material cash-flow issue for businesses that extend credit to customers or purchase stock before collecting their sales proceeds.
Questions for growing businesses
If the business approaches TT$600,000, begin reviewing eligibility before the sales volume reaches the threshold. Keep the rolling calculation, sales forecast, relevant contracts and an explanation of any unusually large transactions. Review whether the entity's activity involves exempt, zero-rated or otherwise specially treated supplies. Those distinctions require more than counting every receipt in the bank account.
Set regular review dates with an accountant or competent tax professional and verify current guidance directly with IRD. Records that support the threshold also help when applying for finance, expanding a shop or reviewing profitability. Business registration, VAT readiness and banking should form one coordinated administrative plan.
A rolling-turnover example for an expanding shop
Assume a shop's relevant commercial supplies were TT$35,000 per month for its first six months and TT$55,000 per month for the following six. The total over those twelve months would be TT$540,000, below the IRD's published TT$600,000 threshold. That does not end the review. If sales continue at TT$55,000 per month, the twelve-month rolling calculation will change as older TT$35,000 months leave the window and newer TT$55,000 months enter it.
After three additional months at TT$55,000, a rolling twelve-month total would comprise three months at TT$35,000 and nine months at TT$55,000, totalling TT$600,000. The business must also consider whether its forecasts already provide evidence of supplies expected to meet or exceed the threshold, as the IRD's registration rule expressly includes relevant expected supplies. The dates of the obligation and the classification of supplies should be confirmed with IRD or a qualified adviser.
This example assumes that all the turnover counted is relevant to the statutory test. Businesses with exempt, zero-rated, mixed or otherwise specially treated activities should seek individual guidance. Keep sales books, issued invoices, contract values and monthly calculations so a registration decision can be supported by evidence.
Action checklist
- Review the dedicated IRD VAT Application for Registration guidance, rather than an older unspecific article.
- Calculate relevant commercial supplies over each rolling 12-month period.
- Keep a dated forecast supported by orders or contracts where future turnover is relevant.
- Check the applicant's correct legal entity and gather the IRD's current supporting forms and IDs.
- Separate VAT accounting, invoices and remittances from sales revenue once registered.
Questions people ask
Is the VAT threshold TT$500,000 or TT$600,000?
The IRD's dedicated VAT registration page states TT$600,000 effective 1 January 2023. An older self-employed explainer may still display TT$500,000.
Does the threshold mean profit?
No. The IRD describes commercial supplies, and an assessment should follow the VAT rules for relevant supplies and any forecasts.
Does incorporating a company automatically create VAT registration?
No. VAT is an IRD tax-registration process with its own conditions and supporting information.
