Nigerian Payroll Tax — The Employer's Monthly Rhythm (2026)

Every Nigerian employer of staff runs the same monthly payroll-tax rhythm. The rhythm has five steps that repeat each month and one annual step that closes the year. Naming each step in order is how a payroll team — in-house or outsourced — keeps the cycle clean across the year.

The five monthly steps:

1. Run the payroll for the month. Compute gross pay per employee, apply allowable reliefs, derive chargeable income, and produce the payslip.
2. Compute the PAYE figure per employee against the new Nigeria Tax Act 2025 progressive bands. The figure is the personal income tax the employer remits on the employee's behalf.
3. Group employees by state of residence and produce a separate PAYE schedule per state IRS. An employer with employees in multiple states files multiple schedules — one per state IRS.
4. Generate the Remita Retrieval Reference per state IRS through the state IRS portal and pay the total monthly PAYE for that state through Remita.
5. Download the filing acknowledgement and the payment confirmation and save in the employer's payroll-tax compliance file against the period.

The annual step that closes the year:

6. File Form H1 (Employer Annual Returns) at each state IRS where any employee was resident during the year, by 31 January of the following year. The H1 summarises every employee's gross income, reliefs, taxable income, PAYE deducted, and PAYE remitted across the twelve months.

This article walks each step. The audience is the employer — typically the HR or finance officer running payroll, the in-house chartered accountant overseeing tax compliance, or the company secretary signing the H1. The employee-side view of the same monthly cycle — what shows up on the payslip and how the employee verifies the remittance lands — lives at PAYE.

The Nigeria Tax Administration Act 2025 and the Nigeria Tax Act 2025, signed by the President on 26 June 2025 and effective from 1 January 2026, revised the personal income tax band structure and tightened the compliance framework around the employer's PAYE obligation.

For the employer-side payroll-tax picture specifically:

The substantive changes for the employer:

• New PIT bands apply through PAYE from January 2026. The 0% band on the first ₦800,000 of annual chargeable income is the headline change; the higher bands run 15%, 18%, 21%, 23%, 25% in sequence. The employer's payroll system needs the new band logic in place from the January 2026 payroll cycle onward. Where the payroll system has not been updated, the deductions are over- or under-stated against the current law.
• New rent relief applies through PAYE where the employee has claimed it. The Nigeria Tax Act 2025 rent relief — 20% of annual rent paid, up to a ceiling of ₦500,000 per year — reduces the employee's chargeable income before PAYE applies. The employer's payroll system needs the relief configurable per employee, applied from the month the employee notifies HR with rent documentation.
• The 13-digit Tax ID is the figure each PAYE remittance reads against. Employers updated payroll systems through Q1 2026 to capture the 13-digit Tax ID per employee alongside the legacy 10-digit format where one is on file. The wider Tax ID retrieval walkthrough at how to get a TIN covers the employee-side route the employer signposts at onboarding.
• The Personal Income Tax Act's penalty regime for late employer remittance remains the employer-side risk. PITA's 10% late-remittance penalty plus interest at the CBN rate plus margin remains the operational floor; senior employer personnel can be personally liable in serious or persistent non-remittance cases.

The framework's substantive intention is to expand the tax base while reducing the marginal burden on lower-and-middle income employees. The employer's discipline is to implement the new bands correctly in payroll and to maintain the routine remittance cycle without slippage.

The employer's payroll-tax operation interacts with three institutions, and naming which holds which piece of the framework keeps the routine compliance discipline tidy.

For the employer-side payroll-tax picture specifically:

• The State Internal Revenue Service receives the monthly PAYE remittance and the annual Form H1 for the state where each employee is resident. The state IRS holds the employer's Employer Tax File and the per-employee PAYE history. LIRS for Lagos employees, FCT-IRS for FCT employees, OYIRS for Oyo, RIRS for Rivers, KIRS for Kano, and the equivalent state IRS elsewhere.
• The Joint Revenue Board operates the central Tax ID infrastructure that both NRS and the state IRSes query against. The employer's payroll system reads each employee's 13-digit Tax ID from the JRB-coordinated database; the figure is the key the state IRS matches each remittance against.
• The Nigeria Revenue Service does not receive PAYE — PAYE is exclusively a state-IRS competency under PITA. The federal NRS interacts with the employer on the CIT, VAT, and WHT lines; the PAYE remittance does not route through NRS. The employer's own CIT filing position at NRS is a separate cycle covered at how to file a tax return.

The single most common employer-side routing error is to expect PAYE to feed the federal NRS dashboard. It does not. PAYE feeds the state IRS of each employee's residence; the federal NRS holds no record of the employer's PAYE compliance. The employer's federal-tax compliance and state-tax compliance are separate dashboards at separate authorities, and reconciling both is the routine year-end discipline.

Before the first PAYE remittance is due, the employer registers as a PAYE-remitting entity at each state IRS where any employee is resident.

1. 1
   Confirm which state IRSes are in scope
2. 2
   Prepare the registration bundle
3. 3
   Open the state IRS portal and complete the employer registration
4. 4
   Receive the Employer Tax File number
5. 5
   Repeat for each state where employees are resident

The registration is free at every state IRS. The cost is the operational time — typically two to five working days per state IRS depending on the platform maturity and whether an in-person verification visit is required. Established employers maintain the registration record current with any change in principal place of business, principal officer, or entity-level CAC details through the state IRS portal's update surface.

The monthly PAYE computation against the Nigeria Tax Act 2025 bands is the substantive payroll-tax work. The flow is mechanical once the band structure and the reliefs are in the payroll system.

1. 1
   Derive gross monthly income per employee
2. 2
   Apply allowable reliefs per employee
3. 3
   Derive monthly chargeable income
4. 4
   Apply the Nigeria Tax Act 2025 bands and compute PAYE
5. 5
   Produce the payslip showing each line

The computation is mechanical once the payroll system holds the band structure and the per-employee reliefs. The substantive work is in maintaining the per-employee data (Tax ID, state of residence, rent-relief documentation, pension-contribution rate, NHF participation) current as employees onboard, change residence, or update their relief positions. The data-maintenance discipline is what keeps the monthly computation clean.

After the monthly computation, the employer remits the total PAYE per state IRS through the Remita route from the state IRS portal.

1. 1
   Group the month's PAYE figures by state IRS
2. 2
   Sign in at each state IRS portal against the Employer Tax File number
3. 3
   Upload the monthly PAYE schedule
4. 4
   Generate the Remita Retrieval Reference and pay
5. 5
   Download the filing acknowledgement and the payment confirmation

The remittance is free at the state IRS portal. The cost is the PAYE figure itself, which the employer has already deducted from employees' gross pay. Late-remittance penalties under PITA sit at 10% of the unpaid figure plus interest at the CBN rate plus margin per month of delay; the penalty regime starts accruing from the day after the published deadline. Most state IRSes operate weekend and public-holiday rollover rules (if the 10th falls on a Saturday, Sunday, or public holiday, the deadline rolls to the next working day); the state IRS portal confirms the active deadline for any given month.

Form H1 is the annual employer return summarising every employee's year-end PAYE position. The form is due at each state IRS where any employee was resident during the year, by 31 January of the year following the year of assessment.

1. 1
   Reconcile the year's PAYE schedules per employee per state IRS
2. 2
   Prepare the Form H1 file per state IRS
3. 3
   Open each state IRS portal and submit the H1
4. 4
   Address any reconciliation query from the state IRS
5. 5
   Save the H1 acknowledgement

Form H1 filing is free at the state IRS portal. The cost is the operational reconciliation time, typically two to three working days for an established payroll team per state IRS. Late H1 filing attracts a penalty under PITA on the same basis as late monthly remittance (10% of the under-reported figure plus interest where the H1 surfaces under-remittance); a clean H1 against clean monthly schedules attracts no penalty.

Late or short PAYE remittance is the most operational employer-side risk in the cycle. The penalty regime and the recovery route are worth naming explicitly.

• Late monthly remittance. Under PITA the late-remittance penalty is 10% of the unpaid figure plus interest at the CBN minimum rediscount rate plus a published margin per month of delay. The penalty starts accruing from the day after the published state IRS deadline (typically the 11th of the month, where the 10th is the deadline). A one-month slip on a ₦500,000 monthly PAYE figure attracts ₦50,000 penalty plus the interest accrual; the longer the delay the larger the cumulative figure.
• Under-remittance. Where the employer remits less than the figure computed against the schedule (a typing error at the RRR, a misallocation across state IRSes, a payroll-system computation error), the state IRS reconciles the under-remittance at the next monthly cycle or at the year-end H1. The 10% penalty applies on the under-remitted figure, with interest. The fix is to remit the shortfall through a fresh RRR against the relevant state IRS as soon as the under-remittance is identified.
• Non-filing of monthly schedule. Filing the schedule is distinct from remitting the cash. A schedule not filed by the deadline attracts a state-IRS-published filing-default penalty (the figure varies by state IRS); the substantive issue is that without the schedule the state IRS cannot allocate the cash against employees. Address by filing the schedule retrospectively at the state IRS portal.
• Non-filing of Form H1. Annual return non-filing attracts a separate penalty under PITA and complicates every subsequent year's compliance position because the H1 reconciliation across years cannot complete without each year's H1 on file. The state IRS may also withhold any subsequent employer-side TCC against the missing H1 record.
• Persistent non-remittance. Where an employer persistently fails to remit deducted PAYE, the state IRS can escalate to the wider penalty regime under PITA — the principal officers can be personally liable, the entity's bank accounts can be subject to garnishment under court order, and the state IRS can publish the entity as a non-compliant employer. The escalation is rare for a routine commercial employer but the legal framework is in place; the operational discipline of remitting on time is what keeps the relationship within routine.

The route to restore compliance after any slip is to file the back schedule, pay the back remittance with the penalty alongside, address any reconciliation query from the state IRS, and then resume the routine monthly cycle. The state IRS support desk publishes guidance on the back-filing route for larger or older defaults; a chartered tax practitioner can negotiate a payment-plan arrangement where the back figure is significant.

The state IRS may audit any employer's PAYE-remittance record. The audit reads against the records the employer maintains; clean records make the audit straightforward.

The records the employer maintains:

• The per-employee register with name, NIN, 13-digit Tax ID, BVN, state of residence, date of joining, date of leaving (where applicable), basic salary, allowances, pension fund administrator, NHF participation status, and current rent-relief documentation.
• The monthly payroll file with gross pay per employee, reliefs deducted per employee, chargeable income per employee, PAYE deducted per employee, net pay per employee, and the payroll summary per state IRS.
• The monthly PAYE schedule filed at each state IRS, with the state IRS portal acknowledgement.
• The Remita Retrieval Reference and the bank payment evidence for each monthly remittance per state IRS.
• The annual Form H1 filed at each state IRS, with the portal acknowledgement and any reconciliation correspondence.
• The benefit-in-kind valuations where any non-cash benefits are part of the compensation package (company cars, employer-provided housing, employer-paid insurance).
• The Tax Clearance Certificate issued to the employer at NRS and at the relevant state IRSes against the entity's PAYE compliance record.

The audit reads against this record. A clean record produces a routine audit; a missing or inconsistent record produces follow-up queries that lengthen the audit and consume operational time. Maintaining the records monthly through the cycle rather than reconstructing at audit time is the operational discipline that keeps the audit routine.

For mid-and-large employers the monthly PAYE remittance flows from the entity's corporate bank account, typically at Tier 2 or Tier 3 in the wider CBN-tier framework. The banking context bears on the operational reliability of the cycle.

The employer-side practical takeaways from the banking-tier framework:

• A Tier 2 corporate account supports routine monthly PAYE remittance within typical employer cash-flow ranges. Most SME employers operate the PAYE remittance from a Tier 2 account.
• A Tier 3 corporate account is the routine setup for mid-and-large employers where the monthly PAYE figure exceeds Tier 2 transaction caps. The Tier 3 account documentation includes the entity's current Tax Clearance Certificate from NRS; a lapsed TCC complicates the account-opening and account-refresh discipline at the corporate KYC desk.
• Bank-counter payments via Remita RRR take 24 to 48 hours through the bank's clearing cycle before Remita confirms to the state IRS; card payments through the state IRS portal typically reconcile within the hour. For a tight-deadline remittance close to the 10th, card payment is the lower-risk route.
• The bank's Remita reconciliation desk is the relevant route where any PAYE-remittance RRR has stuck between bank and state IRS; the tax payment pending walkthrough covers the diagnostic and recovery sequence in fuller detail.

A clean PAYE-remittance record across the past three years of assessment is the substantive eligibility test for the employer's state IRS Tax Clearance Certificate against the entity's PAYE position. The TCC enables several downstream employer-side surfaces.

For the employer specifically the surfaces that read the entity's PAYE-compliance TCC include:

• CERPAC renewal at NIS for expatriate employees. A foreign expatriate employee's CERPAC renewal reads the employer's current TCC against the entity's PAYE record. A lapsed TCC stalls the CERPAC renewal; the expatriate's right to continue residence depends on the employer maintaining PAYE compliance.
• Government tender bidding. Federal and state procurement portals read both the entity's NRS-side TCC (for federal-tax compliance) and the entity's state-IRS-side TCC (for PAYE compliance) at tender submission. A bidder with one TCC but not the other is incomplete.
• Tier 3 corporate bank-account opening and refresh. Major banks include the entity's PAYE-compliance TCC in the Tier 3 corporate KYC bundle, particularly for entities with significant PAYE-paying establishments. The bank reads the TCC alongside the entity's CAC documents and Tax ID.
• Annual returns at CAC. From 2026 the CAC and NRS-state IRS data-sharing reads the entity's overall tax-compliance position at the CAC annual return cycle; an employer not current on PAYE may surface a flag at the CAC side.

The shared employer-side pattern is that clean monthly PAYE remittance and clean annual H1 filing are the inputs that produce the clean compliance record the downstream surfaces read. The wider TCC walkthrough including the application route per authority lives at tax clearance certificate.

The employer-side payroll-tax question connects out to several adjacent walkthroughs across the Tax cluster and beyond.
