Guinea Tax Filing Guide 2026

Overview — Tax Filing in Guinea

The Direction Générale des Impôts (DGI) is the tax administration authority in Guinea. The DGI has been modernising its systems to improve taxpayer services, including the introduction of online filing and payment portals. Taxpayers register on the DGI portal, obtain a Numéro d'Identification Fiscale (NIF), and file all returns electronically or in person. The system covers income tax (IIT and CIT), TVA, PAYE (retenue à la source), withholding taxes, and registration duties. The tax year is the calendar year (1 January to 31 December) for all taxpayers unless an alternative accounting period is approved by DGI.

Numéro d'Identification Fiscale (NIF)

A NIF is mandatory for all taxpayers in Guinea — individuals, companies, partnerships, trusts, and other entities. The NIF is a unique identifier used for all tax transactions. To obtain a NIF, register on the DGI portal or in person at the local tax office with valid identification (national ID card, passport, or business registration certificate). A NIF is required for many transactions including opening a bank account, registering property, importing/exporting goods, obtaining a business permit, and participating in government tenders. Companies must have a NIF before they can operate legally in Guinea.

Filing Deadlines

Different taxpayers have different filing deadlines in Guinea:

• Self-employed individuals — annual return by 30 April of the following year
• Companies — annual return by 30 April following the tax year
• PAYE (employers) — monthly return by the 15th of the following month
• TVA — monthly or quarterly return by the 15th of the following month/quarter
• Withholding tax — monthly return by the 15th of the following month
• Registration duties — at the time of the transaction (property transfer, inheritance)

Late filing attracts penalties under the General Tax Code, including a percentage of the tax due plus monthly interest on any unpaid tax. More severe penalties apply for failure to file after DGI notices or for tax evasion.

Self-Assessment & Quarterly Instalments

Self-employed individuals and companies must estimate their annual tax liability and pay in quarterly instalments. The instalment payment system requires taxpayers to pay estimated tax in advance based on the prior year's liability or a reasonable estimate of the current year's liability. Instalments are typically due by the end of each quarter. If the actual tax computed in the annual return exceeds the total instalments paid, the balance is due at the time of filing. If instalments exceed the actual tax, a refund may be claimed. Underpayment of instalments may attract interest.

Penalties & Enforcement

DGI has broad enforcement powers under the General Tax Code. Key penalties include:

• Late filing — percentage of tax due plus monthly interest
• Late payment — monthly interest on unpaid tax
• Failure to maintain records — fixed fine
• Tax evasion — substantial penalty plus possible criminal prosecution
• Non-issuance of TVA invoice — fine per invoice
• Failure to register for tax — back taxes plus penalties

DGI may issue enforcement notices to banks and debtors to collect unpaid taxes, seize and sell assets, or initiate legal proceedings. Tax clearance certificates may be required for certain transactions and may be denied to non-compliant taxpayers.

FAQs

Can I file my tax return online?

DGI has been developing online filing systems. Depending on your taxpayer category and location, online filing may be available or mandatory. Check with your local DGI office for the current filing methods.

What records do I need to keep?

Taxpayers must keep records for at least 5 years from the end of the tax year. Records include income statements, receipts, invoices, bank statements, contracts, and asset registers. DGI may audit taxpayers and request documents at any time.

How long does it take to get a Tax Clearance Certificate?

If all returns are filed and taxes paid, a Tax Clearance Certificate (attestation de situation fiscale) can typically be obtained from DGI within a few business days to 2 weeks.
