Nigeria VAT Return — Monthly VAT-F001 Filing

Confirm the client is a VAT-registered person with FIRS, holds a valid Tax Identification Number (TIN), and has annual turnover above the NGN 25,000,000 registration exemption threshold under VATA s.8 as amended by Finance Act 2020. Identify filing period, check for any excess input credit carried forward from the prior month, and flag if the client makes government-entity supplies requiring WHT-VAT documentation.

Review all sales, revenue receipts, and bank credits for the period. Classify each supply as standard-rated (7.5%), zero-rated (exports, diplomatic), or exempt (basic food, medical, education, residential rent, financial services, public transport per VATA First Schedule). Apply 7.5% output VAT to all standard-rated supplies. Flag government-entity payments (FGN / MDAs / LGA) for WHT-VAT verification. Identify non-resident digital service receipts requiring reverse-charge review under VATA s.10A.

Review all purchase invoices and bank debits for the period. Identify input VAT claimable at 7.5% on business purchases that carry a valid VAT invoice meeting VATA s.10 requirements (supplier name, TIN, VAT amount, sequential number). Exclude input VAT on purchases used for exempt supplies. Where the client makes both taxable and exempt supplies, apportion residual input VAT by the taxable-to-total-revenue ratio. Disallow any input claim without a valid VAT invoice.

Compute net VAT payable as Output VAT (A2) minus Allowable Input VAT (B3). If the result is negative, determine whether the excess credit is carried forward or a refund is to be claimed from FIRS. Add any credit carried forward from the prior period. Finalise the Nigeria VAT Working Paper, complete all reviewer flags (registration confirmed, input invoices verified, mixed-supply apportionment documented, foreign-currency conversion at CBN rate applied), and prepare the return data for entry into TaxPro Max.

Log in to TaxPro Max (taxpromax.firs.gov.ng) using the client's TIN credentials. Enter the finalised output VAT, input VAT, and net VAT figures from the working paper into the monthly VAT return. Attach supporting schedules where required. Submit the return and generate the FIRS acknowledgement receipt. Initiate payment of VAT due via the TaxPro Max payment gateway before the 21st-of-month deadline; late filing attracts a 5% penalty per month plus NGN 50,000, and late payment attracts 5% plus interest at the CBN Monetary Policy Rate.
