Zambia Tax Filing Guide
Zambia's tax filing is fully digitised through the ZRA TaxOnline platform. Annual income tax returns must be filed by 30 April for the previous calendar year. Monthly PAYE returns are due by the 10th of the following month. Businesses pay instalment tax in quarterly instalments. Late filing attracts a penalty of 5% of tax due plus interest at the Bank of Zambia policy rate.
ZRA TaxOnline — Zambia's Online Tax Platform
The Zambia Revenue Authority (ZRA) operates a fully online tax filing system called TaxOnline. All tax returns — including PAYE, VAT, income tax, withholding tax, and CGT — are filed through TaxOnline. Taxpayers must register on TaxOnline using their Taxpayer Identification Number (TPIN). The platform supports online payment via mobile money, bank transfer, or card. TaxOnline is mandatory for all taxpayers; paper filing is only available in exceptional circumstances with ZRA approval.
Annual Income Tax Return — 30 April Deadline
All individuals with income subject to tax must file an annual income tax return by 30 April following the tax year (1 January to 31 December). The return is filed through TaxOnline. Key categories:
- Employees (PAYE only): Simplified return confirming income and tax deducted
- Self-employed individuals: Full return with business income, expenses, and instalment tax paid
- Companies: Corporate income tax return due by 30 April following the financial year end
Even employees whose tax is fully withheld should file a return to confirm their tax position and claim any refunds.
Monthly PAYE Returns
Employers must file a monthly PAYE return via TaxOnline by the 10th of the following month. The return declares gross salaries, taxable benefits, PAYE deducted, NAPSA contributions, and NHIMA contributions. Payment must accompany the return. Late filing attracts a penalty of 5% of the tax due plus interest. Employers with nil returns must still file.
Instalment Tax — Quarterly Payments
Businesses (self-employed individuals and companies) must pay instalment tax in advance. The instalment tax is based on estimated current year liability or prior year's liability. The payment schedule is:
- 1st instalment: Due 31 March (25% of estimated tax)
- 2nd instalment: Due 30 June (25%)
- 3rd instalment: Due 30 September (25%)
- 4th instalment: Due 31 December (25%)
The final liability is calculated in the annual return, with the difference settled or refunded.
Penalties and Interest
ZRA imposes the following penalties for non-compliance:
- Late filing: 5% of the tax due per month of delay
- Late payment: Interest at the Bank of Zambia policy rate plus a penalty
- Failure to register: Penalties apply for failure to register for tax
- Tax evasion: Penalty of up to 100% of the tax evaded plus criminal prosecution
Record-Keeping Requirements
Taxpayers must retain accounting records, invoices, and supporting documents for at least 6 years. Companies must retain audited financial statements. ZRA may request these documents during a tax audit. Electronic records are acceptable if readily accessible.
