A finance manager opens the payroll reconciliation on the eighth of the month and finds two problems: last month’s PAYE was paid late, and three NAPSA schedules were never submitted. The cash may be available, but payment alone will not necessarily clear the employer’s record.

Late NAPSA and PAYE arrears need a structured response. As of October 2026, employers must deal with the underlying monthly returns, employee records, principal amounts, penalties and interest. Many businesses use outsourced payroll services Zambia support when internal teams need to rebuild several months of payroll evidence before engaging ZRA or NAPSA.

This guide explains the practical order of work. Statutory rates, waiver conditions and portal processes should receive review from our qualified team before publication or before an employer relies on them for a filing decision.

Start by separating PAYE from NAPSA

PAYE and NAPSA arise from the same payroll, but ZRA and NAPSA administer them separately. A payment that resolves a ZRA balance does not correct a NAPSA schedule, and a cleared NAPSA account does not remove an outstanding Monthly PAYE Return ITF/P16.

Create two arrears files before making further payments. For each month, record gross payroll, employee names, TPINs, PAYE deducted, NAPSA contributions, amounts paid, return status, payment references and the balance shown on the relevant portal.

This step matters because payroll arrears often begin with a posting problem rather than a cash problem. An employer may have made a bank payment but submitted no matching schedule, or submitted a return with an incorrect employee TPIN.

Confirm the monthly deadlines

ZRA requires employers to file and remit PAYE through the Monthly PAYE Return ITF/P16 by the 10th day of the following month. For example, PAYE deducted during October 2026 falls due by 10 November 2026.

NAPSA also requires the monthly contribution schedule and payment by the 10th day of the following month. The matching due dates can make payroll administration look simple, but the return formats, validations and penalties differ.

Employee TPINs have been mandatory in monthly PAYE returns since 1 October 2022. Before submitting historical ITF/P16 returns, reconcile every employee’s TPIN with payroll records. A return that contains incomplete or incorrect identification data can create a compliance issue even where the employer has calculated the tax correctly.

Understand the cost of paying PAYE late

ZRA applies more than one charge where an employer misses PAYE obligations. The financial exposure depends on whether the employer filed the return, paid the tax, or failed to do both.

Late PAYE payment

Late PAYE payment attracts a penalty of 5% of the unpaid PAYE for each month or part-month it remains unpaid. ZRA also charges interest at the Bank of Zambia discount rate plus 2%, from the due date until payment.

The phrase “each month or part-month” deserves attention. If an employer pays one day into a new month, ZRA may treat that period as another month for the 5% charge. Do not budget for a single 5% penalty unless ZRA has confirmed the assessment.

Late PAYE return filing

A late Monthly PAYE Return ITF/P16 attracts 1,000 penalty units for an individual employer and 2,000 penalty units for a limited company, for each month or part-month. ZRA’s August 2025 PAYE leaflet values one penalty unit at K0.40, which produces a K400 charge for an individual employer and K800 for a limited company per affected month.

This filing penalty is separate from late-payment charges. A limited company that neither files nor pays can therefore face the monthly K800 filing penalty, the 5% monthly or part-month payment penalty, and interest.

Worked example: a missed PAYE cycle

Take a Lusaka trading company with 12 staff and K40,000 in PAYE deductions for September 2026. The finance officer submits the ITF/P16 on 18 November and pays the principal on the same date, after missing the 10 October deadline.

The company should expect ZRA to assess the late-payment penalty at 5% for each month or part-month outstanding, plus interest at the applicable Bank of Zambia discount rate plus 2%. Because it is a limited company and filed late, it may also face K800 for October and K800 for November, subject to ZRA’s assessment of the filing periods.

The more important lesson is operational. The company should have filed the ITF/P16 by 10 October even if it could not settle the K40,000 immediately, then approached ZRA with a documented plan for the principal and assessed amounts.

Understand NAPSA arrears and penalties

NAPSA formal-sector contributions equal 10% of gross earnings. The employer contributes 5% and deducts 5% from the employee’s earnings.

As of 6 October 2026, NAPSA’s employer portal shows a monthly earnings ceiling of K28,920.30 and a maximum total monthly contribution of K2,892.03. Apply the ceiling carefully because contributions do not continue to rise above it, although payroll teams should confirm the applicable ceiling for each historical period before correcting arrears.

NAPSA applies a cumulative 10% penalty to contributions unpaid by the due date. Current NAPSA guidance states 10%, and employers should not rely on older material that refers to a 20% rate.

The National Pension Scheme Act No. 72 of 2026 and Statutory Instrument No. 62 of 2026 brought pension reforms into effect in 2026. NAPSA reported that the reforms retained the 10% monthly or part-month late-contribution penalty position reflected on its portal.

Why schedules matter as much as payment

The common mistake is paying NAPSA without submitting or correcting the corresponding monthly return. In the NAPSA iCare employer account, an unmatched payment can remain unposted or unbalanced, leaving the employer unable to demonstrate that a specific month is regularised.

Before requesting any waiver, submit missing monthly returns, including nil returns where appropriate. Then correct unposted or unbalanced payments, settle unpaid periods and resolve every flagged issue in iCare.

Worked example: an unbalanced NAPSA payment

Take a Kitwe engineering contractor with 18 employees. It paid approximately K22,000 to NAPSA for two historic months, but it had not submitted the schedules and used a payment reference that the employer account did not match.

The employer sees the debit in its bank statement and assumes the debt has ended. In practice, the iCare account may still show missing returns and unresolved balances, which can block a penalty-waiver application.

The right sequence is to rebuild the two monthly schedules from payroll, submit or correct them in iCare, ask NAPSA to address the unbalanced payment, and pay any remaining principal before considering the penalty position. If the contractor had completed this reconciliation before paying, it could have avoided a second round of follow-up with its payroll records and bank evidence.

A step-by-step process to clear arrears

1. Freeze further errors

Bring the current payroll month under control first. Calculate current PAYE and NAPSA separately, verify employee TPINs for PAYE, and diarise the 10th day deadline for both institutions.

Do not allow historic arrears work to cause a new default. A controlled current-month process stops the liability from growing while the finance team addresses older periods.

2. Reconstruct payroll month by month

Use payroll registers, employment contracts, payslips, bank payment records and prior submissions to build a month-by-month reconciliation. Match each employee’s gross earnings to PAYE deductions and NAPSA contributions.

For NAPSA, check the monthly ceiling applicable to each period rather than applying the October 2026 figure backwards without review. For PAYE, confirm the tax tables and currency treatment that applied in the affected period before amending figures.

If the turnover of a small employer does not justify maintaining specialist payroll capacity, do not rely on an occasional spreadsheet review. Outsourced payroll services Zambia arrangements can give management a defined monthly reconciliation, filing calendar and approval record.

3. File all outstanding PAYE returns

Submit every outstanding ITF/P16 through ZRA TaxOnline or at ZRA, using reconciled employee TPINs and payroll deductions. Filing every period gives ZRA a complete basis to assess principal PAYE, penalties and interest.

Do not start by paying a rounded estimate. First establish which months are absent, which returns need correction, and which payments ZRA has already allocated.

4. Correct NAPSA records in iCare

Use the NAPSA iCare employer account to submit missing or nil monthly returns and correct schedules that do not match payments. Resolve unposted payments and all flagged items before submitting a waiver request.

Keep payment confirmations, schedules and correspondence in one controlled file. NAPSA may need evidence when the employer asks it to identify or reallocate a historical payment.

5. Settle the principal before relying on waivers

Neither ZRA nor NAPSA waiver arrangements remove the underlying PAYE or NAPSA principal. Build the cash-flow plan around the tax and contributions first, then assess whether penalties and interest qualify for relief.

ZRA’s Extended Voluntary Disclosure Scheme runs from 17 September 2026 to 31 December 2026. It offers a 100% waiver of accrued penalties and interest where the principal tax is settled, but employers should confirm that PAYE arrears qualify before assuming eligibility.

For NAPSA, applications relating to penalties from before 6 December 2022 remain open until 7 January 2027. NAPSA also indicates that a 75% waiver may be available for COVID-period penalties after 7 January 2026 and before 8 January 2027, subject to settlement and the stated conditions.

6. Obtain evidence that each account is clear

After payment, check the ZRA and NAPSA account status rather than assuming a receipt closes the matter. Ask the relevant institution to clarify any remaining balance, unallocated payment, return error or waiver decision.

This final check matters during due diligence, financing discussions and payroll audits. A bank confirmation proves money left an account. It does not always prove that ZRA or NAPSA posted it against the intended period.

Put controls around the next payroll run

Arrears often reveal a governance gap rather than one late payment. Assign one person to prepare the payroll, another to review totals and employee changes, and an authorised executive to approve payment before the 10th.

Maintain a monthly payroll pack with the signed payroll summary, ITF/P16 confirmation, ZRA payment proof, NAPSA schedule confirmation, NAPSA payment proof and exception notes. This record gives directors a practical compliance trail and makes year-end reconciliation less uncertain.

We also recommend a short monthly variance review. If headcount, gross payroll, PAYE or NAPSA changes materially from the prior month, management should ask why before payment leaves the business.

For enterprises with several sites or expatriate payroll issues, outsourced payroll services Zambia support can provide a controlled calendar and independent review without removing management’s responsibility for statutory compliance.

Frequently Asked Questions

What is the deadline for PAYE and NAPSA in Zambia?

Employers must file and remit PAYE to ZRA by the 10th day of the following month. NAPSA contributions and the monthly contribution schedule also fall due by the 10th of the following month.

What happens if a company pays PAYE late?

ZRA charges 5% of unpaid PAYE for every month or part-month it remains unpaid, plus interest at the Bank of Zambia discount rate plus 2%. A limited company that files its ITF/P16 late also faces 2,000 penalty units, valued in ZRA’s August 2025 PAYE leaflet at K800 per month or part-month.

Can an employer obtain a waiver for NAPSA penalties?

NAPSA provides waiver routes subject to conditions, including the regularisation of returns, payments and account issues. For pre-6 December 2022 penalties, NAPSA states that applications remain open until 7 January 2027, while a 75% COVID-period waiver may apply within the stated 2026 to 2027 window.

Can we pay arrears before filing the missing returns?

You can make a payment, but payment without the matching PAYE return or NAPSA schedule can create allocation and reconciliation problems. File or correct the returns, then verify that ZRA or NAPSA posted the payment to the right period.

A late payroll obligation deserves prompt action, but it also deserves a clean audit trail. Speak With Our Team or visit our outsourced payroll services Zambia hub page to discuss a structured arrears review and ongoing payroll compliance.
