What Tax Records Should You Keep as a Nigerian Freelancer?

For a freelancer, good record keeping makes it easier to work out how much you earned, identify relevant business expenses and support the information you provide in your tax return.

The 2026 Personal Income Tax Guidelines require taxable individuals to file an annual return showing income from every source. For income from a trade, business, profession or vocation, the return should be accompanied by an audited financial statement or a statement of accounts attested to by the taxpayer.

So, what should you actually keep?

Start with your income records

Keep records of every payment you receive from your freelance work.

This can include client invoices, payment confirmations, bank statements, payment-platform statements and records from freelance platforms such as Upwork.

Your records should make it possible to trace a payment back to the work that generated it. If a client pays you ₦500,000, for example, you should have something showing who paid you, what the payment was for, when you received it and how much you received.

This becomes even more important when you work with multiple clients or receive payments through different platforms.

Keep your client and contract records

Your financial records should not exist separately from the work that generated the money.

Keep contracts, engagement letters, invoices, statements of work and other documents that explain the relationship with your client.

For foreign clients, keep the relevant payment and contractual records even when the money is received through an international payment platform or into a foreign-currency account.

These documents can help establish what a payment represents when you need to reconcile your income.

Keep records of your business expenses

Freelancers also spend money to run their businesses.

You might pay for design software, cloud storage, internet services, professional subscriptions, accounting services or other costs connected to your work.

Keep the receipts, invoices and payment evidence for these expenses.

The Nigeria Tax Act allows deductions for expenses that are wholly and exclusively incurred in the production of income, subject to the rules and restrictions in the Act. That means you should not assume that every personal expense becomes a tax deduction simply because you work from home.

Your records should help show what the expense was, how much you paid and its connection to your freelance activity.

Don’t forget your tax records

If tax has already been deducted from a payment you received, keep the relevant Withholding Tax certificate or evidence of the deduction.

Also keep copies of tax returns you file, tax payment receipts and other correspondence or documents relating to your tax obligations.

These records can become important when reconciling what you earned with what has already been deducted or paid.

Keep your foreign-currency records

If you earn from clients outside Nigeria, don’t rely only on the naira amount that eventually appears in your account.

Keep the original payment record, the currency received, the date of payment, the amount converted and the relevant bank or payment-platform statement.

This gives you a clearer record of how the income was received and makes your accounts easier to reconcile.

Keep your records for six years

This is one part freelancers should take seriously.

The Nigeria Tax Administration Act 2025 requires books and records covered by the Act to be kept for at least six years after the year of assessment in which the income relates.

So, don’t clear out old invoices, receipts or payment records simply because you have filed your tax return for that year.

Keep them somewhere secure and make sure your digital records can still be accessed when you need them.

Your records should tell one clear story

A good record-keeping system should allow you to connect the dots:

Client → invoice → payment → expenses → tax records

You should be able to look at your records and understand where your income came from, what you spent to earn it and how your tax position was calculated.

You don’t need to wait until tax season to start putting this together. Keep the records as the transactions happen, and tax preparation becomes much easier when the time comes.
