The clock ticks loud this year for anyone still unsure how the transition from FIRS to NRS reshapes their annual tax filing.
Nigeria retired the Federal Inland Revenue Service on January 1, 2026, and the Nigeria Revenue Service now runs the federal tax administration.
Salaried workers who once assumed their employers handled everything now face a rude discovery, because the law requires you to file your own return.
Freelancers, side hustlers, and small business owners face the same expectation, and the enforcement muscle behind that expectation looks nothing like previous years.
Missing the March 31 individual filing deadline attracts penalties, bank restrictions, and audit exposure that can dwarf any tax bill you tried to avoid.
This guide walks through NRS personal income tax filing end to end, covering documents, portal steps, payment channels, and options when funds run short.
Before you touch any portal, understand that most individuals file with their State Internal Revenue Service, not directly with the NRS itself.
Nigeria collected ₦28.3 trillion in tax revenue in 2025, and the 2026 target of ₦40.7 trillion depends heavily on individual compliance, BusinessDay reported.
The NRS portal replaces FIRS for how to file personal income tax
The Federal Inland Revenue Service became the Nigeria Revenue Service on January 1, 2026, following the Nigeria Revenue Service Establishment Act of 2025, the NRS confirmed on its portal.
The old TaxProMax platform is being phased into a self-service system that consolidates federal obligations under one taxpayer dashboard, NRS Portal Guide explained.
Existing 10-digit TINs remain valid alongside a new 13-digit Tax ID linked directly to your National Identification Number, NRS Portal Guide reported.
You retrieve the new Tax ID at taxid.nrs.gov.ng using your NIN and date of birth, and the process takes under five minutes, KeepAm noted.
Most salaried and self-employed individuals file personal income tax returns with their State Internal Revenue Service, not directly with the NRS itself.
Who files where under the new regime
- Individuals with employment or self-employment income file with State IRS such as LIRS in Lagos or FCT-IRS in Abuja.
- Companies, partnerships, and federal officers file directly with the Nigeria Revenue Service self-service portal.
- Employers file the annual PAYE summary for their staff with the relevant State IRS by January 31 each year.
- Freelancers and small business owners without registered companies file with the State IRS where they reside.

Documents you need before starting NRS personal income tax filing
Getting your paperwork in order before you log in saves hours of frustration, tax consultant Prosperity Olawuyi noted in a recent NRS Portal Guide breakdown.
You need your 10-digit TIN, your new 13-digit Tax ID, your NIN, and your Bank Verification Number to authenticate on any state portal.
Salaried workers should also gather their 2025 payslips, their employer’s Payer ID, and any P9 or PAYE summary the employer issued for the year.
Self-employed filers need bank statements covering January 1 to December 31, 2025, plus receipts for business expenses and any withholding tax credit notes received.
Rent relief claims require your tenancy agreement or receipts showing annual rent, since the 20% deduction is capped at ₦500,000 under the new law.
Personal income tax filing document checklist
- 13-digit Tax ID and legacy 10-digit TIN.
- National Identification Number and Bank Verification Number.
- 2025 payslips or P9 summary from your employer.
- Bank statements covering the full 2025 fiscal year.
- Withholding tax credit notes from clients or platforms that paid you.
- Pension contribution statements from your Pension Fund Administrator.
- Rent receipts or tenancy agreement supporting the 20% rent relief claim.

“All of us must file our returns, including those earning low income. You must file returns by 31st March of the year in respect of the previous fiscal year” Taiwo Oyedele, Minister of State for Finance, said during a Joint Revenue Board webinar, according to CrispNG.
How to file PIT nigeria on the self-service portal, step by step
Filing looks different on each state portal, but the underlying logic follows a universal sequence that mirrors the NRS Self-Service Portal, taxngr.com reported.
Open your browser and visit your State IRS website, or go to nrs.gov.ng if you file federally as a company or partnership.
The homepage typically shows a login card in the top-right corner with fields for Tax ID, password, and captcha verification.
After signing in, look for a menu labeled Annual Returns, Form A, Form H1, or Individual Filing on the dashboard.
Populating your income schedule and applying reliefs
Select the assessment year 2025, since 2026 filings cover income earned between January 1 and December 31 of the preceding year.
Populate the income schedule with employment income, business or freelance income, rental income, and any other taxable sources for the year.
Apply your reliefs by entering pension contributions, life insurance premiums, National Housing Fund payments, and rent paid to unlock the 20% rent relief deduction.
The system runs the ₦800,000 tax-free threshold automatically and returns your chargeable income and net tax payable in real time.
Submitting and generating your assessment notice
Upload supporting documents in PDF, review every entry carefully, and click submit to generate an Assessment Notice with a unique reference number.
The Assessment Notice functions as your official tax bill, and the portal redirects you to Remita or Webpay for payment settlement.
Save the receipt number and download your filing confirmation, since these documents anchor future tax clearance requests and audit responses.
New personal income tax bands and reliefs to know before filing
The Nigeria Tax Act 2025 replaces the Personal Income Tax Act with a progressive band structure starting at 0% for annual income up to ₦800,000.
The old Consolidated Relief Allowance is gone, replaced by rent relief calculated as the lower of 20% of annual rent or ₦500,000, Punch reported.
Termination benefits enjoy a higher exemption ceiling of ₦50 million, up from the previous ₦10 million cap under the repealed law, NALTF explained.
Pension contributions, National Housing Fund payments, and life insurance premiums remain deductible, provided you attach supporting documentation when filing your return online.
The reforms build a fairer, simpler, and more worker-friendly tax system, Oyedele told finance managers during the Joint Revenue Board session.
Payment channels, common errors, and what to do if you cannot pay
Payment on the NRS platform routes through Remita or Interswitch Webpay, with settlement accepted from any Nigerian bank, debit card, or USSD channel.
Bank branches also accept over-the-counter payment against a Remita RRR reference number, which the portal generates during the assessment stage, Remita documentation confirms.
Invalid TIN errors rank among common portal complaints, and they usually stem from records the JTB cleanup did not update, NRS Portal Guide reported.
Fix an Invalid TIN error by contacting NRS support to merge your legacy record with the new Tax ID rather than opening a fresh account.
If you cannot pay the full assessment, request an installment plan from your State IRS or the NRS Tax Office through a written application.
Filing the return on time protects you from the ₦100,000 first-month late-filing penalty, even when the payment itself is delayed, NRS Portal Guide explained.
Common NRS filing errors to avoid
- Filing on the wrong platform, such as using NRS instead of State IRS for personal income tax.
- Creating a new account when the legacy TIN just needs merging with the new 13-digit Tax ID.
- Skipping the Nil Return when income falls below ₦800,000, which still triggers a ₦100,000 fine.
- Failing to attach rent receipts, which invalidates the 20% rent relief claim on your return.
- Missing March 31 entirely, which stacks ₦50,000 monthly penalties on top of the initial ₦100,000 fine.
What happens if you miss the personal income tax filing deadline
Missing March 31 triggers an immediate ₦100,000 penalty in the first month, followed by ₦50,000 each subsequent month under the Nigeria Tax Administration Act.
False declarations attract fines of up to ₦1 million or three years in prison under the Nigeria Tax Administration Act 2025, Remote Solutions Africa reported.
The Post No Debit rule under Section 60 lets the NRS freeze your bank account without a court order once tax debts are established.
Filing a Nil Return remains mandatory for earners below the ₦800,000 tax-free threshold, since compliance records matter more than tax owed, NRS Portal Guide noted.
The NRS also cross-references bank data, payroll records, and filings using AI-powered analytics, so silence is no longer a viable strategy for salaried Nigerians.
