Bosnia Tax Filing Guide 2026

Overview — Tax Filing in Bosnia

Each entity in Bosnia has its own tax administration. The FBiH Tax Administration (Porezna Uprava FBiH) and the RS Tax Administration (Poreska Uprava RS) operate separate online portals for tax filing, payments, and compliance. Taxpayers must register with the relevant entity's tax authority based on their residence or place of business. The tax year is the calendar year (January to December). Taxpayers may apply for a different accounting period with approval. The systems are increasingly digital, with electronic filing becoming mandatory for most taxpayers.

Tax Identification Number (TIN)

A TIN is mandatory for all taxpayers in Bosnia. The TIN is a unique identifier used for all tax matters. Individuals typically receive a TIN upon first registration for tax or when obtaining a personal identification number. Companies receive a TIN upon incorporation. The TIN is required for many transactions including opening a bank account, registering property, and invoicing. Non-residents earning Bosnia-source income may need to obtain a TIN for withholding tax purposes.

Filing Deadlines

Key filing deadlines in Bosnia:

• Personal income tax return — due by 30 April of the following year (both entities)
• Corporate income tax return — due by 31 March of the following year
• Quarterly instalments — due by the end of each quarter (31 March, 30 June, 30 September, 31 December)
• Monthly payroll (PAYE) — due by the 15th of the following month
• VAT returns — monthly or quarterly by the 10th of the following month

Late filing attracts penalties ranging from BAM 100 to BAM 5,000 depending on the delay and the taxpayer's history. Interest on late payment accrues at the statutory rate (~0.03% per day).

Self-Assessment & Instalments

Self-employed individuals and companies must estimate their annual tax liability and make quarterly advance payments. The instalments are based on the prior year's tax liability. If the actual tax exceeds the instalments paid, the balance is due at the time of filing the annual return. If instalments exceed the tax due, a refund may be claimed. Underpayment of instalments may attract interest.

Online Filing

Both entity tax administrations offer online filing portals. The FBiH system (ePorezna) and the RS system (ePoreska) allow taxpayers to register, file returns, make payments, view tax history, and download certificates. Registration on the portal requires a valid TIN and identification. Electronic filing is mandatory for businesses and increasingly encouraged for individuals. Payments can be made via bank transfer or through authorised payment service providers.

FAQs

Do I need to file a tax return if my only income is from employment?

Generally, if all your tax was withheld at source by your employer (PAYE), you may not need to file a separate return. However, if you have additional income (rental, capital gains, foreign income), you must file.

What records do I need to keep?

Taxpayers must keep records for at least 5 years. Records include income statements, receipts, invoices, bank statements, contracts, and asset registers.

How long does it take to get a tax refund?

Tax refunds are typically processed within 30-60 days of filing the annual return. Delays may occur if the return is selected for audit.
