Angola Tax Filing Guide 2026

Overview — Tax Filing in Angola

The Administração Geral Tributária (AGT) administers tax collection in Angola. The tax year runs from 1 January to 31 December. Taxpayers must file annual returns and make periodic payments depending on their tax obligations. All filings are electronic through the Portal do Contribuinte (e-AGT platform). Taxpayers must have a valid NIF (Número de Identificação Fiscal) and digital certificate to access the portal. The AGT has increasingly automated tax compliance, with pre-filled returns available for salaried employees whose employers submit monthly withholding declarations.

Annual Filing Deadline — 31 May

The annual tax return deadline for both individuals (IIT) and companies (CIT) is 31 May of the year following the tax year. For the 2025 tax year, the return is due by 31 May 2026. The annual return captures total income, deductions, credits, and tax payable for the calendar year. Individuals file Model 1 (simplified) or Model 2 (detailed) depending on income type. Companies file the IRPC annual return (Model 22). The return must be accompanied by supporting documentation including financial statements for companies and income certificates for individuals.

Quarterly Estimated Payments

Companies and self-employed individuals must make quarterly estimated tax payments during the tax year. The quarterly payment system is designed to accelerate tax collection and reduce the burden of a single annual payment:

• First payment — Due by 15 May (25% of prior year's tax liability)
• Second payment — Due by 15 August (25% of prior year's tax liability)
• Third payment — Due by 15 November (25% of prior year's tax liability)
• Fourth payment (optional) — Due by 15 February of the following year

New businesses may estimate their quarterly payments based on projected profits. If actual tax liability is lower than estimated payments, the excess is refunded or offset against future liabilities. Underpayment of quarterly estimates may result in interest charges.

VAT Monthly Returns

VAT-registered taxpayers must file monthly VAT returns by the 15th of the month following the reporting period. The VAT return (Declaração Periódica de IVA) reports output VAT on sales and input VAT on purchases. The net VAT payable (output less input) must be remitted with the return. Exporters and businesses with excess input VAT may claim refunds subject to AGT verification. Small taxpayers with annual turnover below AOA 10 million are not required to register for VAT.

INSS Monthly Filings

Employers must file monthly social security returns and remit INSS contributions by the 15th of the following month. The INSS return lists all employees, their gross salaries, and the calculated contributions (5% employee + 8% employer, capped at AOA 200,000/month per employee). Late filing of INSS returns attracts penalties of up to AOA 100,000 plus interest. Employers must also submit annual INSS declarations reconciling monthly contributions with annual payroll.

Penalties for Non-Compliance

Angola imposes penalties for late filing, late payment, and non-compliance:

• Late filing of annual return — AOA 50,000 to AOA 200,000 fine
• Late payment of tax — Interest at the legal rate (currently 7.25% per annum) plus a penalty of 4% per month up to 30%
• Failure to maintain records — AOA 100,000 to AOA 500,000 fine
• Tax evasion — Criminal penalties including imprisonment for serious cases
• Failure to register for tax — AOA 200,000 to AOA 1,000,000 fine

The AGT has enhanced its enforcement capabilities, including automated cross-referencing of data from banks, employers, and property registries.

FAQs

Can I file my tax return in person at an AGT office?

Most filings are electronic through the Portal do Contribuinte. However, taxpayers may visit AGT service centres for assistance with registration, certificate requests, and technical support. Paper returns are accepted only in exceptional circumstances.

What happens if I miss the 31 May deadline?

Late filing attracts a fine of AOA 50,000 to AOA 200,000 plus interest on any unpaid tax at 7.25% per annum plus a 4% monthly penalty charge. You should file as soon as possible to minimise penalties.

Do I need a digital certificate to file electronically?

Yes, a digital certificate (Certificado Digital) is required to access the Portal do Contribuinte. The certificate can be obtained from the AGT or authorised certification providers and must be renewed annually.
