Documents You Need to File Your Nigerian Tax Return in 2026

Complete checklist of documents needed to file your Nigerian tax return for the 2026 tax year. Covers employees, self-employed, investors, and first-time filers under the NTA 2025.

Filing your Nigerian tax return is not the hard part. Gathering the documents you need before you sit down to file — that is where most people stall. A missing rent receipt delays your rent relief claim. A lost WHT credit note means you pay tax that has already been deducted. A pension statement you cannot find means you cannot prove your deduction. By the time you realise what is missing, it is January, the deadline is approaching, and chasing documents from landlords, clients, and banks becomes a scramble.

This guide lists every document you need — organised by taxpayer type — so you can collect them throughout the year and file your 2026 return without surprises, delays, or missed deductions.

Documents Every Taxpayer Needs (Regardless of Category)

Whether you are employed, self-employed, or filing as an investor, these documents form the foundation of every Nigerian tax return.

1. Tax Identification Number (TIN)

Your TIN is required on every tax form, every payment, and every correspondence with the tax authority. For individuals, your 13-digit National Identification Number (NIN) now serves as your Tax ID under the NTA 2025. For companies, the CAC registration number serves as the Tax ID.

Verify your Tax ID at taxid.nrs.gov.ng before filing. If your name, address, or other details are incorrect in the system, resolve the discrepancy before submitting your return. A return filed with an unverifiable or mismatched TIN can be treated as incomplete.

2. Previous Year’s Tax Return and Assessment

If you filed a return for the 2025 tax year (under the old PITA regime), keep a copy available. Your State IRS may reference your prior filing when reviewing your 2026 return — particularly if your income has changed significantly. It also helps you identify deductions you claimed previously that may still apply or that have changed under the NTA 2025.

If this is your first time filing, you do not need a prior return. But be aware that the State IRS may ask about previous years if they believe you should have been filing earlier.

3. Bank Statements

Bank statements for all accounts through which you received income or made tax-related payments during 2026. For employees, this confirms salary receipts. For the self-employed, it establishes gross business income and documents expense payments. For investors, it shows dividend credits, interest credits, and investment transactions.

Download or request statements covering January to December 2026 for every account — personal, business, and investment. Some State IRS offices specifically request bank statements as part of the filing. Even where they do not, statements are your strongest evidence if any figure on your return is queried.

4. Rent Documentation (for Rent Relief)

To claim rent relief (20% of annual rent paid, capped at ₦500,000), you need:

• A signed tenancy agreement covering 2026
• Rent payment receipts or a rent receipt letter from your landlord
• Bank transfer evidence showing the payment from your account to the landlord (if paid electronically)

The documentation must show the amount paid, the period covered, and who paid. If your spouse also claims rent relief on the same property, each spouse needs evidence of their own payment from their own account. If you live in employer-provided accommodation, you cannot claim rent relief — your return should instead reflect the accommodation benefit (20% of gross income).

5. Pension Contribution Statement

Request an annual statement from your Pension Fund Administrator (PFA) showing total contributions to your Retirement Savings Account (RSA) during 2026. The statement should break down employee contributions, employer contributions, and any voluntary contributions.

For employees, the mandatory contribution is 8% of Basic + Housing + Transport. For the self-employed claiming a voluntary pension deduction (up to 20% of income), the PFA statement is your primary evidence. Without it, the deduction cannot be verified.

Contact your PFA in January to request the statement. Most PFAs — including ARM Pension, Stanbic IBTC Pension, Leadway Pensure, FCMB Pensions, and Trustfund Pensions — generate annual statements through their online portals or mobile apps.

6. National Housing Fund (NHF) Evidence

If you contribute to the NHF (2.5% of basic salary), obtain a statement or deduction schedule from your employer or the Federal Mortgage Bank of Nigeria showing total NHF contributions for 2026. This deduction reduces your chargeable income.

7. National Health Insurance Scheme (NHIS) Evidence

If you make employee contributions to the NHIS, obtain documentation of total contributions for 2026. Your payslip or a statement from your employer’s health insurance provider will typically suffice.

8. Life Insurance Premium Receipts

If you hold a qualifying life insurance policy with a Nigerian insurer and paid premiums during 2026, obtain the premium payment receipt or annual statement from the insurer. The actual premium amount is deductible from your chargeable income.

Additional Documents for Employed Taxpayers

If you earn a salary or wages from an employer, you need the following in addition to the documents above.

9. Annual Tax Deduction Summary From Your Employer

Your employer should provide you with an annual summary showing your gross pay, all statutory deductions (pension, PAYE, NHF, NHIS), and net pay for 2026. This is the document your individual return must reconcile with — under the NTAA 2025, the employer files a PAYE return (Form H1) by 31 January, and your individual return must be consistent with the figures reported by your employer.

If your employer does not proactively provide this summary, request it in writing. You are entitled to it, and you need it to complete your return accurately.

10. Final Payslip for December 2026 (or Year-End Payslip)

Your December payslip (or a year-end cumulative payslip, if your employer provides one) shows total gross pay, total PAYE deducted, total pension contributed, and other year-to-date figures. Cross-reference this with the annual tax deduction summary to ensure consistency.

11. Employment Contract or Letter of Employment

Not always required for filing, but useful if your salary structure changed during the year, if you started a new job, or if the State IRS queries the composition of your income. It confirms your Basic Salary, Housing Allowance, Transport Allowance, and other package components — which determine the correct PAYE computation.

12. Benefits in Kind Documentation

If your employer provides benefits such as a company car, rent-free accommodation, or other assets, obtain documentation showing the employer’s cost (for vehicles and assets) or confirmation of the benefit (for accommodation). These are taxable at defined rates under the NTA 2025:

• Company car: 5% of employer’s acquisition cost per year
• Rent-free accommodation: 20% of gross income
• Other employer-provided assets: 5% of cost per year

Your payslip or annual summary should include the taxable value. If it does not, request confirmation from HR so your return accurately reflects your total taxable income.

13. Previous Employer’s Tax Deduction Statement (If You Changed Jobs)

If you left one employer and joined another during 2026, your former employer should have provided a tax deduction statement showing income earned and PAYE deducted during your period of employment. Your new employer should have factored this into your PAYE computation for the remainder of the year. Include both employers’ records in your return to ensure total income and total PAYE are correctly reported.

Additional Documents for Self-Employed Taxpayers

If you earn income from a trade, business, profession, or freelance work, you need the following in addition to the universal documents.

14. Income Records

A complete record of all business income received during 2026:

• Invoices issued to every client (numbered and dated)
• Payment confirmations (bank alerts, transfer receipts, platform payout reports)
• Contracts and engagement letters (especially for large projects)
• Platform earnings reports (Fiverr, Upwork, Jumia, Konga, ride-hailing apps, or any other marketplace)

Your gross business income is the total of all these receipts for the calendar year. If you operate in cash, a daily sales record or cash receipts book serves this purpose. Your income records must reconcile with your bank statements — discrepancies invite scrutiny.

15. Expense Receipts and Invoices

Every business expense you intend to claim as a deduction requires supporting documentation:

• Receipts for rent, internet, phone, utilities, and data (business portion)
• Software subscription invoices and confirmations
• Equipment and supply purchase receipts
• Transport logs and fuel receipts (business portion)
• Subcontractor invoices and payment evidence
• Professional subscription receipts (ICAN, NBA, COREN, NMA)
• Training, course, and conference receipts
• Insurance premium receipts (professional indemnity, business assets)
• Marketing and advertising invoices (social media ads, signage, website hosting)
• Bank charge statements (transfer fees, POS charges, maintenance fees)

Organise these by category. The State IRS does not typically request every receipt at filing — but they can request any or all during an audit. The NTAA requires records to be maintained for a minimum of six years. An expense without a receipt is an expense you cannot defend.

16. Asset Register and Capital Allowance Computation

If you purchased business assets during 2026 (or in prior years with ongoing annual allowances), prepare:

• A list of all business assets with acquisition dates and costs
• Purchase receipts or invoices for each asset
• Capital allowance computation showing initial allowance (year of purchase) and annual allowance (subsequent years)
• Written-down values carried forward from prior years

Common assets include vehicles, computers, cameras, office furniture, machinery, and tools. The initial allowance (typically 50% for vehicles, computers, and machinery; 25% for furniture) and annual allowance (typically 25% for most assets; 20% for furniture) reduce your adjusted profit before tax bands are applied.

17. WHT Credit Notes

If corporate clients deducted withholding tax from your invoices before payment, each client should have issued you a WHT credit note. Collect every credit note — each one reduces your tax liability by the amount shown.

The credit note must show: the client’s name and TIN, the gross amount, the WHT rate applied, the WHT amount deducted, and the period. Present all credit notes with your annual return. The State IRS cross-references your claimed credits against the client’s WHT remittances to the NRS.

If you did not receive a credit note for a WHT deduction, chase the client now. You are legally entitled to it, and without it, you may pay tax twice on the same income.

18. VAT Records (If VAT-Registered)

If you are registered for VAT, compile your monthly VAT returns and payment confirmations for 2026. Your VAT records should show output VAT charged, input VAT claimed, and net VAT remitted each month. While VAT is a separate obligation from PIT, the State IRS may request VAT records to cross-reference your reported income — VAT-registered turnover should be consistent with the gross income on your PIT return.

Additional Documents for Investment Income

If you earned dividends, interest, or capital gains during 2026, the following documents support correct reporting and credit claims.

19. Dividend Certificates and Statements

Your stockbroker or the Central Securities Clearing System (CSCS) should provide dividend payment statements showing gross dividends, WHT deducted (10%), and net dividends received. For most individual investors, the WHT on dividends is a final tax — you do not need to report it further. But keep the statements as evidence that the tax has been paid, in case your overall income is queried.

20. Interest Income Statements

Banks typically issue annual interest statements or you can extract the information from your account statements. These show gross interest earned, WHT deducted (10%), and net interest credited. As with dividends, the WHT is usually a final tax for individuals, but retain the documentation.

For FGN Bonds, Treasury Bills, and other government securities, retain your investment confirmations and maturity statements. These instruments are tax-exempt — no WHT should have been deducted. If WHT was incorrectly deducted, the documentation supports your refund or credit claim.

21. Capital Gains Records

If you sold shares, property, cryptocurrency, or any other chargeable asset at a profit during 2026, you need:

• Acquisition records: Purchase contract, broker confirmation note, transfer receipt, or exchange transaction record showing the original cost and date of purchase
• Disposal records: Sale contract, broker confirmation note, transfer receipt, or exchange transaction record showing the sale proceeds and date of sale
• Incidental cost records: Broker commissions, legal fees, stamp duties, SEC and NGX fees, Governor’s Consent costs (for property), and exchange or network fees (for cryptocurrency)
• Improvement expenditure records (property): Receipts for capital improvements (renovations, extensions) that increase the property’s value — not routine maintenance

The chargeable gain (disposal proceeds minus acquisition cost minus allowable costs) is taxed at 10%. Unlike WHT on dividends and interest, CGT is self-assessed — you must compute it, report it, and pay it yourself. Accurate records are essential for both the computation and any subsequent audit.

Documents for First-Time Filers

If you are filing a tax return for the first time — whether because the NTAA 2025’s dual filing obligation now requires it or because you have decided to become compliant — you need everything listed above for your taxpayer category, plus:

22. Proof of Tax Registration

Confirm that your Tax ID is active and correctly linked in the NRS system. For individuals, verify your NIN-based Tax ID at taxid.nrs.gov.ng. If your Tax ID is not active or your details are incorrect, you may need to visit your State IRS office with your NIN slip, a valid ID (international passport, driver’s licence, or voter’s card), and proof of address to complete registration or correct the records.

23. State IRS Registration Confirmation

Some State IRS offices require a separate registration before you can file. Check whether your State IRS has an online portal (Lagos uses eTax at etax.lirs.net; other states have their own systems) and whether you need to create an account before filing. If filing physically, confirm the documents required for first-time walk-in registration — typically your Tax ID, a valid ID, proof of address, and your employment or business details.

Documents for Employers Filing PAYE Returns

If you are an employer filing the annual PAYE return (Form H1) by 31 January 2027, you need:

24. Complete Employee Register

A list of every employee who worked for you at any point during 2026 — including those who joined or left mid-year. For each employee: full name, Tax ID, residential address, state of residence, date of joining, and date of leaving (if applicable).

25. Annual Payroll Summary

For each employee: gross annual pay (all components), pension contribution, NHF, NHIS, other statutory deductions, chargeable income, PAYE computed, and PAYE deducted. This forms the body of the Form H1 return.

26. Monthly Remittance Receipts

Payment confirmations for every monthly PAYE remittance made to each State IRS during 2026. You should have 12 remittance receipts per State IRS (one for each month). If you missed or delayed any remittance, the shortfall must be explained and reconciled in the return.

27. Monthly PAYE Schedules

The detailed monthly schedules showing each employee’s deduction for each month. The annual return reconciles against these schedules — total PAYE on the annual return should equal the sum of all monthly deductions across all schedules.

How to Organise Your Tax Documents

The taxpayers who file on time and claim every deduction are the ones who organise documents throughout the year — not the ones who start looking for receipts in February. Here is a practical system:

Create a Tax Folder (Physical or Digital)

Set up a folder at the start of 2026 with sub-folders for each category:

• Income: Payslips, invoices, platform reports, client contracts
• Expenses: Receipts organised by category (rent, internet, transport, software, professional fees)
• Deductions: Pension statements, NHF evidence, NHIS evidence, life insurance receipts, rent documentation
• Investment: Dividend statements, interest statements, capital gains records, FGN Bond confirmations
• WHT: All WHT credit notes received from clients
• Tax filings: Copies of previous returns, assessment notices, payment receipts

Collect Monthly, Not Annually

At the end of each month, spend 15 minutes filing that month’s documents — payslips, expense receipts, WHT credit notes, bank statements. By December, your folder is complete. By January, you are assembling a return, not hunting for documents.

Photograph Paper Receipts

Many Nigerian business expenses generate paper receipts that fade, tear, or disappear. Take a clear photo of every receipt on the day you receive it and save it to your digital tax folder. The photo is your backup if the original is lost. Some State IRS offices accept digital records; for others, the photo helps you reconstruct the information even if the original is unavailable.

Set Calendar Reminders

Request your PFA statement in the first week of January. Request your annual tax deduction summary from your employer by mid-January. Chase any outstanding WHT credit notes from clients by the end of January. File your return by mid-March — giving yourself a two-week buffer before the 31 March deadline.

What Happens If Documents Are Missing

If you cannot locate a document you need for filing:

• Pension statement: Contact your PFA directly. Most can issue a duplicate or replacement statement within a few days. Check their app or portal first — many PFAs make statements available online.
• Rent receipt: Request a signed letter from your landlord confirming the rent amount, payment dates, and property address. Bank transfer evidence (showing payments to the landlord) can substitute for a formal rent receipt.
• WHT credit note: Contact the client’s finance or tax department. They are legally obligated to issue the note and should have records of the WHT remittance. If they cannot provide the note, check whether the WHT has been remitted by the client — your tax adviser or the State IRS may be able to verify this against the NRS records.
• Employer annual summary: Request it from your HR or payroll department. If the employer is unresponsive, use your December payslip (which should show year-to-date totals) as a working substitute, and note the discrepancy in your return if needed.
• Expense receipts: If the original is lost, check for bank or card statements that corroborate the expense, email confirmations (for online purchases), or digital receipts. If no evidence exists, the expense should not be claimed — an unsupported deduction is a risk during an audit.

The principle is straightforward: if you can prove the expense, deduction, or credit, you can claim it. If you cannot prove it, do not claim it. Filing a return with unsupported figures creates more risk than the tax saving is worth.

Final Thoughts

Your tax return is only as good as the documents behind it. Every deduction you claim, every credit you apply, and every figure you report must be supported by evidence that you can produce on request — not just at filing, but for six years afterwards. The NTA 2025 provides meaningful deductions (pension, rent relief, business expenses, capital allowances) and credits (WHT) that can reduce your tax liability significantly. But they are all documentation-dependent. No receipt, no claim.

Start collecting today. Create your tax folder, file documents monthly, photograph every paper receipt, chase WHT credit notes as soon as payments arrive, and request your pension and employer statements in January. By the time 31 March arrives, filing your return should take hours, not weeks.

FAQs About Tax Filing Documents in Nigeria

What is the deadline for filing my 2026 tax return?

Individuals must file by 31 March 2027. Employers must file the annual PAYE return (Form H1) by 31 January 2027. Companies must file CIT returns within six months of their financial year-end. Late filing attracts ₦100,000 for the first month and ₦50,000 for each subsequent month under NTAA Section 101.

Do I need a Tax Identification Number to file?

Yes. Your Tax ID is required on every tax form and payment. For individuals, your 13-digit NIN serves as your Tax ID under the NTA 2025. Verify yours at taxid.nrs.gov.ng. If your Tax ID is not active or details are incorrect, resolve this before filing — a return with an unverifiable TIN may be treated as incomplete.

What if I cannot find my rent receipt?

Request a signed confirmation letter from your landlord stating the rent amount, payment period, and property address. Bank transfer evidence showing payments to the landlord can substitute for a formal receipt. If you have no evidence of rent payment at all, you cannot claim rent relief for that period.

Do I need to keep receipts for business expenses?

Yes. The NTAA 2025 requires all taxpayers to maintain records for a minimum of six years. Every business expense claimed as a deduction must be supported by a receipt, invoice, or bank statement. If you cannot produce the evidence during an audit, the deduction will be disallowed, and additional tax, penalties, and interest will apply.

What documents do I need for capital gains tax?

You need the acquisition record (showing original cost and date), the disposal record (showing sale proceeds and date), and receipts for all incidental costs (brokerage, legal fees, stamp duty, SEC fees). For property, include improvement expenditure receipts. The chargeable gain is disposal proceeds minus acquisition cost minus allowable incidental costs, taxed at 10%.

How do I get my pension statement?

Contact your Pension Fund Administrator. Most PFAs (ARM Pension, Stanbic IBTC Pension, Leadway Pensure, FCMB Pensions, Trustfund Pensions) provide annual statements through their online portals or mobile apps. If you cannot access it online, call or visit your PFA branch and request a printed statement. Do this in January — do not wait until March.

What if my employer has not given me an annual tax summary?

Request it formally in writing from your HR or payroll department. You are entitled to a summary of your gross pay, PAYE deducted, and other statutory deductions for the year. If the employer cannot provide it before your filing deadline, use your December year-to-date payslip as a working substitute. Note any discrepancy in your return and follow up with the employer to reconcile.
