How TaxAudit works
From a pile of documents to records an auditor can follow, in three steps. You stay in charge throughout: the AI suggests, you decide.
How it works
Upload what you have
Certificates, past returns, bank statements, invoices, receipts, payroll. Photos and email forwards work too.
AI organises and checks
It reads each document, files it in the right place, and checks your records against each other.
You fix, approve and export
Clear the issues it finds, approve the results, and download statements and evidence in the formats auditors expect.
Six records, kept complete and consistent
The records NRS and state auditors ask for, checked against each other so the numbers agree.
CAC & Tax Registration
Your name, numbers and address match everywhere.
Tax Filings
Every return filed, acknowledged and paid, and matching your books.
Financial Statements & Bank Records
Statements that balance and agree with your bank.
Sales & Invoices
An invoice behind every sale and every naira of VAT.
Expenses
A receipt behind every expense you claim.
Payroll
Payroll that matches your PAYE and pension remittances.
See exactly what an auditor would question
Your Proof Book marks every record as complete, consistent and proven, and the AI tells you what to fix first, in naira.

June's VAT return declares ₦4,100,000 in sales; your books show ₦4,600,000. Fix this first.
What the AI does for you
Invoices, receipts, bank statements, returns and payroll: it reads each one and files it in the right place.
Sales against VAT returns, payroll against PAYE and pension, statements against your bank.
Every difference is explained in plain language and ranked by the naira at risk.
It suggests; you approve. Nothing is filed or changed without a person saying yes. Read our AI Use Notice.
