VAT Returns in Kenya: A 2026 Monthly Filing Guide for Businesses

By FNJ & Associates

Who must file VAT returns in Kenya?

Every business registered for Value Added Tax under the VAT Act, 2013 is required to file monthly VAT returns in Kenya, regardless of whether the business made any sales or purchases during the month. The filing obligation continues until the business formally deregisters from VAT through KRA. A nil VAT return must be filed in any month with no VAT activity.

VAT registration is compulsory for businesses whose taxable turnover exceeds the registration threshold set under the VAT Act, 2013. Voluntary registration is available below the threshold where the business expects to grow into the obligation or where its customer base requires VAT-compliant invoicing. Once registered, the business charges VAT on standard-rated supplies, claims input VAT on qualifying purchases, and accounts for the net VAT to KRA on a monthly basis.

When are VAT returns in Kenya due?

VAT returns in Kenya are due by the 20th day of the month following the tax period. The VAT3 return for January is due by 20 February, for February by 20 March, and so on. Payment of any VAT payable is due on the same date. Filing late attracts a penalty of KES 10,000 or 5% of the tax due, whichever is higher, under the Tax Procedures Act, 2015, plus interest of 1% per month on the outstanding tax.

Where the 20th falls on a weekend or public holiday, the deadline is treated as falling on the next working day. KRA’s iTax portal generally remains accessible until midnight on the due date, but FNJ recommends filing at least 24 hours in advance to allow for portal congestion or payment processing delays.

How to file VAT returns in Kenya through iTax

Filing VAT returns in Kenya follows a structured iTax workflow. The steps below apply to monthly VAT3 returns for resident registered persons.

Step 1: Reconcile the data sources. Before opening iTax, the business must reconcile the output VAT collected on sales (from the sales ledger, with reference to eTIMS-transmitted invoices) and the input VAT incurred on purchases (from the purchases ledger, with reference to eTIMS-stamped supplier invoices). Where Zoho Books eTIMS integration in Kenya is in place, this reconciliation is largely automated.

Step 2: Log into iTax. At itax.kra.go.ke, log in with the business PIN and password. Navigate to Returns > File Return > Value Added Tax.

Step 3: Download and complete the VAT3 template. iTax provides an Excel template with separate tabs for sales, purchases, and the summary. Populate sales with all output VAT transactions including standard-rated, zero-rated, exempt, and export sales. Populate purchases with all input VAT transactions, distinguishing between purchases from registered and unregistered suppliers.

Step 4: Validate, generate, and upload. Run the validation function in the template. iTax will flag missing PINs, invalid invoice formats, and mathematical errors. Once clean, generate the upload .zip and return to iTax to submit.

Step 5: Pay any VAT due. If the return shows VAT payable (output VAT exceeds input VAT), generate a payment slip and pay through a KRA-appointed bank, M-Pesa Paybill 222 222, or mobile banking. Payment must be received by the 20th to avoid penalty and interest.

Output VAT, input VAT, and the monthly net position

VAT returns in Kenya operate on the principle of value addition – the business charges output VAT on sales, claims input VAT on related purchases, and pays the difference to KRA. Where input VAT exceeds output VAT in a month, the excess is either carried forward to the next month or, in defined circumstances, claimed as a refund from KRA.

Output VAT is charged at the standard rate on most goods and services, at zero rate on exports and specified supplies, and at the exempt rate on items listed in the First Schedule to the VAT Act, 2013. Input VAT is claimable on purchases made for taxable supplies, supported by eTIMS-compliant invoices from VAT-registered suppliers. Purchases that are not used for taxable supplies, or that are made from unregistered suppliers, do not generate claimable input VAT.

Apportionment applies where the business makes both taxable and exempt supplies. The input VAT on purchases used for mixed purposes must be apportioned based on the ratio of taxable supplies to total supplies. FNJ supports clients with the apportionment computation and the supporting documentation required to defend the position during a KRA audit.

VAT refund claims under VAT returns in Kenya

VAT refunds in Kenya are available in specific circumstances under the VAT Act, 2013. The most common refund scenarios are exporters carrying continuous excess input VAT, businesses making zero-rated supplies, businesses that have ceased trading with unutilised input VAT credit, and overpayments arising from KRA assessments later reduced or reversed. The refund must be claimed within 24 months of the period to which it relates.

Refund claims require comprehensive supporting documentation – sales and purchase ledgers reconciled to the VAT3 returns, eTIMS-stamped invoices for every claimed input, bank statements supporting payments, export documentation for zero-rated exports, and any agreements supporting the supply classification. KRA verifies refund claims through a desk audit, and in many cases a field audit, before approving the refund.

FNJ supports clients with VAT refund claims under VAT returns in Kenya by preparing the claim file, reconciling the underlying transactions, responding to KRA verification queries, and where necessary, defending the claim through the objection and appeal process. The firm’s audit and tax integrated approach is particularly useful here – the same documentation standards used in statutory audit also support successful refund recovery.

Common errors when filing VAT returns in Kenya

FNJ observes recurring errors that delay processing or trigger KRA review notices on VAT returns in Kenya. The most common is filing using sales records that do not reconcile to eTIMS transmissions – any mismatch flags the return for review. Claiming input VAT on invoices from unregistered suppliers, on invoices without valid eTIMS stamps, or on personal expenses dressed up as business expenses is similarly flagged.

Other recurring errors include misclassifying zero-rated supplies as exempt or vice versa, failing to apply apportionment for mixed supplies, claiming input VAT on items that are specifically blocked from claim under the VAT Act (such as passenger motor vehicles for businesses outside the motor trade), and failing to account for VAT on imported services where the reverse charge mechanism applies. Each error can trigger an assessment with penalties and interest.

Handling a KRA VAT audit on your VAT returns in Kenya

KRA’s VAT audit programme is increasingly data-driven, with the audit team often arriving with pre-populated discrepancies between the business’s filings and third-party data such as eTIMS transmissions, supplier filings, and bank statements. A well-managed VAT compliance routine reduces audit exposure substantially because the supporting documentation already exists and ties to the filed returns.

When KRA initiates a VAT audit, the business should respond promptly to the engagement letter, prepare the requested records, and engage tax advisers if the audit is likely to challenge specific positions. FNJ regularly defends VAT audits on behalf of clients, including responding to queries, attending KRA meetings, and where the assessment is unjustified, lodging objections and appeals. Each audit response is built around the underlying VAT returns in Kenya already filed.

Frequently Asked Questions

When are VAT returns in Kenya filed?

VAT returns in Kenya are filed monthly by the 20th day of the month following the tax period. The return for January is due by 20 February, for February by 20 March, and so on. A nil VAT3 return must be filed in any month with no VAT activity, until the business formally deregisters from VAT.

What is the penalty for late VAT returns in Kenya?

Late VAT returns in Kenya attract a penalty of KES 10,000 or 5% of the VAT due, whichever is higher, under the Tax Procedures Act, 2015. Interest of 1% per month accrues on any unpaid VAT from the date it fell due. Persistent non-filing can trigger KRA default assessments and enforcement action.

Can input VAT be claimed without an eTIMS-stamped invoice?

No. From 2024, input VAT on VAT returns in Kenya can only be claimed where the supplier has issued an eTIMS-stamped invoice. Invoices without an eTIMS stamp do not support a claim and the input VAT will be disallowed in any KRA audit. Buyers should refuse to accept non-compliant invoices from suppliers.

How long does a VAT refund claim take in Kenya?

VAT refund claims under VAT returns in Kenya are typically processed within several months once KRA’s verification audit is complete. Timelines vary by claim complexity, documentation quality, and KRA’s current processing capacity. FNJ supports clients in preparing claim files that minimise verification delays.
