VAT compliance in The Gambia starts before a return is prepared. A business must know whether it is required or eligible to register, classify each supply correctly, issue compliant invoices and receipts, preserve purchase evidence, reconcile output VAT against allowable input VAT, and file and pay by the deadline. A calculator can check arithmetic, but it cannot decide whether a product is exempt, prove an export, or submit a return.
This guide was verified on August 25, 2026 against current public pages and documents from the Gambia Revenue Authority, or GRA. GRA's website currently states a 15% standard rate, a D2 million compulsory registration threshold, a D1 million voluntary registration threshold, and monthly returns due 15 days after month end. Those rules can change, so businesses should confirm the live GRA position before registration, invoicing or filing.
Use the Gambia VAT Calculator to add or extract VAT in dalasi. It uses the published 15% standard rate and allows 0% only after the user confirms an export of goods or services with retained evidence. The calculator is a planning tool. It does not offer an exemption as zero-rating and does not file with GRA.

VAT is a consumption tax, not a tax on profit. GRA describes it as applying to taxable supplies of goods and services in The Gambia and to taxable imports. The business collects output VAT on taxable sales, reviews input VAT supported by qualifying purchases, and accounts for the net position through the return.
Check registration before charging VAT
GRA states that a business with taxable supplies of D2 million or more in a tax year must register and charge VAT. A business with taxable supplies of D1 million or more may apply voluntarily. These thresholds refer to taxable supplies, not profit, cash in the bank or total assets. Exempt supplies should not be silently included or excluded without checking their legal classification.
Build a registration monitor from invoices, sales records and expected contracts. Separate standard-rated, zero-rated and exempt supplies. Keep a monthly total, year-to-date total, forecast and note of any classification uncertainty. If a business is near the threshold, it should ask GRA when the liability starts and which documents are required rather than waiting for the annual accounts.
Registration is not merely a number to print on an invoice. GRA's VAT guide says registrants must display their VAT registration certificate at business premises, issue VAT-inclusive invoices and receipts, quote VAT-inclusive prices, keep proper business records, and submit returns for every tax period. A business that has applied voluntarily should not charge VAT until GRA confirms the registration.
GRA also provides a deregistration route. Its FAQ says a business registered for two years, with taxable turnover below D1 million in the previous 12 months, may apply if it has filed regularly during that period. This is an application, not automatic closure. Keep filing until GRA confirms the registration status.
Keep standard-rated, zero-rated and exempt supplies separate
The standard rate is 15%. GRA says 0% applies to exports of goods and services. Zero-rating does not mean that every foreign customer, foreign payment or cross-border message qualifies. The business should retain the contract, invoice, delivery or service evidence, customer details, payment record and any customs or transport documents that establish the exact export.
Exempt supplies are different from zero-rated supplies. GRA's public VAT guide lists examples including specified basic foods, educational services, prescription drugs, medical services, agriculture and aquaculture products and inputs, certain insurance and financial services, domestic transport, residential property, and limited household electricity and water consumption. Each item has boundaries. Do not turn the examples into a universal product list or assume a mixed invoice has one treatment.
The distinction matters for input tax. A zero-rated taxable supply remains within the VAT system, while an exempt supply is not simply a taxable sale at 0%. Input tax recovery can depend on the use of the purchase and the evidence held. A business making both taxable and exempt supplies should obtain transaction-specific advice on allocation instead of claiming every purchase invoice.
Imported VAT also needs its own record. GRA's import VAT calculator states that the tax base includes CIF value, customs duty, excise and other fiscal charges. A domestic VAT calculator should not be used as a substitute for the customs declaration and import assessment.
How to add and extract 15% VAT
For a VAT-exclusive amount, multiply the taxable amount by 15%. Add the VAT to the net amount to obtain the VAT-inclusive total. For a VAT-inclusive amount, divide the total by 1.15 to find the net amount, then subtract the net amount from the total to find the VAT element. Keep the unrounded result in the calculation record and apply the business's approved rounding policy consistently.
| Task | Formula at 15% | Control |
|---|---|---|
| Add VAT | VAT = net amount × 0.15 | Confirm the supply is standard-rated. |
| Find gross amount | Gross = net amount × 1.15 | Show that the quoted price includes VAT. |
| Extract VAT | VAT = gross amount × 15 ÷ 115 | Use only when the amount is already VAT-inclusive. |
| Find net from gross | Net = gross amount ÷ 1.15 | Reconcile net plus VAT back to gross. |
GRA's own guide gives a factual VAT-inclusive example of D1,150,000. Dividing the total by 115 and multiplying by 15 produces a VAT element of D150,000, leaving a net amount of D1,000,000. This is an official formula illustration, not a fictional customer transaction.
Use the Gambia VAT Calculator for the arithmetic, then keep the result beside the actual invoice classification and source documents. A correct multiplication cannot repair the wrong tax treatment.
Build a controlled monthly filing workflow
GRA lists the VAT return as monthly and due 15 days after month end. The safest operating assumption is that classification, ledger cleanup and evidence review must finish before that deadline, not begin on it. Confirm the exact calendar date, submission route and payment channel for each period with GRA, especially around holidays or a portal change.
- Freeze the sales register. Capture invoice number, date, customer, supply description, net amount, VAT rate, VAT amount, gross amount, credit notes and classification evidence.
- Freeze the purchase register. Record supplier identity, invoice reference, purchase purpose, net amount, VAT amount, payment evidence and whether the purchase supports taxable, exempt or mixed activity.
- Reconcile output VAT. Compare the sales register with the general ledger, cash or payment records, invoice sequence and credit-note log. Investigate missing and duplicate numbers.
- Review input VAT. Remove unsupported, duplicate, private, exempt-use or otherwise ineligible items. Do not claim from a quotation, pro forma document or an invoice that cannot be tied to the business purchase.
- Prepare the return. Carry the reviewed totals into the current GRA form or filing channel. If output VAT exceeds allowable input VAT, the difference is the amount payable. If input VAT exceeds output VAT, retain the support for the credit or refund position.
- Review and authorise. A second person should compare the return to the reconciliation, check unusual rates, exports, exemptions, large credits and manual adjustments, and approve the final submission.
- File, pay and archive. Preserve the submitted return, acknowledgement, payment receipt, bank proof, reconciliation, registers, adjustment notes and source snapshot together.
GRA's Domestic Taxes Department describes the system as self-assessment. The taxpayer makes the declaration and pays the amount due. Responsibility does not disappear because a form, accountant or software produced the numbers.
Invoice, purchase and refund evidence
GRA says VAT registrants must issue VAT-inclusive invoices and receipts and advertise or quote VAT-inclusive prices. Use a stable invoice sequence and show the supplier identity, customer details where required, date, description, net amount, VAT treatment, VAT amount and gross total. Correct an invoice through a traceable credit or adjustment record rather than deleting the original transaction.
For input VAT, keep the original supplier evidence and a clear business-purpose link. Match the purchase register to the payable ledger, bank or cash record, inventory or expense account, and supplier statement where available. Duplicate invoice references, altered documents, purchases outside the registered business and invoices unrelated to taxable activity should be flagged before the return.
GRA's FAQ identifies refund eligibility for specified organisations and for VAT registrants in credit for three consecutive months. It also refers to registrants whose zero-rated supplies make up at least half of supplies in the preceding 12 months. A credit return is not proof that cash is immediately repayable. Retain the return history, export evidence, invoice pack and any GRA correspondence, then follow the current refund process.
The GRA Finance and Accounting page says domestic tax payments can be made through designated partner banks and identifies the pay-in slip as supporting evidence. Channels can change. Confirm the current method, reference details and receipt process before payment, and never treat a bank debit alone as proof that the tax account was credited correctly.
Controls that prevent VAT filing errors
Use one classification list. Product, service, export and exemption decisions should have an owner, authority source, effective date and review note. Do not let staff choose tax treatment from memory at invoice time.
Monitor registration turnover. Review taxable supplies monthly and after a large contract. Record why a supply is excluded from the threshold. Escalate uncertainty before invoices are issued.
Separate output, input and payment accounts. Output VAT collected is not sales revenue. Input VAT is not automatically recoverable. The payable or credit balance should reconcile from source registers to the return and general ledger.
Control exports. A 0% rate should fail closed until the exact supply and export evidence have been checked. A foreign currency, international customer name or cross-border bank transfer is not enough by itself.
Track corrections. Every adjustment should identify the original invoice or return period, reason, amount, approver and supporting document. Do not overwrite a closed register because that breaks the audit trail.
File nil returns while registered. No sales or no tax payable does not end the return obligation. Keep the nil-period review and filing acknowledgement with the monthly file.
Protect taxpayer data. VAT files can contain customer, supplier, banking and commercial information. Restrict access, avoid public links and analytics, use synthetic data for testing, and follow an approved retention policy.
Refresh the source before configuration changes. This article records what GRA published on August 25, 2026. Before a new tax period or software update, recheck the rate, thresholds, deadline, forms, portal and payment route. Document any unresolved issue and obtain guidance from GRA or a qualified Gambian tax adviser.

Frequently asked questions
What is The Gambia's standard VAT rate?
GRA states that the standard rate is 15%. It states that exports of goods and services are zero-rated. Exempt supplies must remain a separate classification.
What are the VAT registration thresholds?
GRA publishes compulsory registration from D2 million in annual taxable supplies and voluntary registration from D1 million. Confirm how the threshold applies to the business's exact supplies and timing.
When is the VAT return due?
GRA lists a monthly return due 15 days after month end. Confirm the exact filing date and channel for the period, and complete the reconciliation before submission.
Can a business stop filing if there were no sales?
No. GRA's guide says a registered person must continue filing for each tax period even when no tax is payable. Deregistration requires GRA approval.
Does AfroTools decide whether a supply is exempt?
No. The calculator handles arithmetic for the standard rate and an evidence-gated export option. It does not classify products, approve exemptions, register taxpayers or submit returns.
