Tax in Tunisia

Who is the tax authority and where do filings live?

Tunisia's Direction Generale des Impots (DGI), under the Ministry of Finance, administers Tunisia's tax system [SC1]. Customs is administered by Direction Generale des Douanes (DGD). DGI operates through Direction des Grandes Entreprises for large taxpayers and regional Bureaux de Controle. Filings flow through the e-Tax portal at e-tax.gov.tn. The credentialed Tunisian tax-and-accounting professions are Expert-Comptable regulated by the Ordre des Experts-Comptables de Tunisie. Substantive law: Code de l'IRPP et de l'IS (codified single statute since 1990 with successive Loi de Finances amendments), Code de la TVA, Code des Droits et Procedures Fiscaux, Loi de Finances 2024, and successive amendments. Tunisia is a Greater Arab Free Trade Area (GAFTA) member and has progressively engaged with EU framework under successive Association Agreement reviews.

What is the tax year and when are returns due?

The individual tax year is the calendar year. Personal income tax returns are due 25 February-25 May of the year following the tax year (varying by income category and filer status under successive Loi de Finances) [SC1]. Wage earners' income tax is fully withheld monthly by employers. Corporate fiscal years align with the calendar year (with limited exception); annual corporate IS returns are due 25 March of the year following fiscal year-end. Quarterly advance corporate tax instalments apply (acomptes provisionnels). TVA returns are filed monthly by the 28th of the following month. Annual financial statements are required for in-scope corporations.

Who is a Tunisian tax resident?

Under the Code de l'IRPP et de l'IS, an individual is tax resident in Tunisia if (a) maintaining their habitual abode in Tunisia, OR (b) being physically present in Tunisia for more than 183 days in a calendar year, OR (c) having their centre of business or vital interests in Tunisia [SC2]. Residents are taxed on worldwide income; non-residents on Tunisian-source income at flat or schedular rates (typically 25 percent on most categories with treaty rates applying). Treaty tie-breakers apply.

What are the personal income tax rates?

Personal income tax brackets for 2024 (post-Loi de Finances reform): 0 percent up to TND 5,000; 26 percent on TND 5,001-20,000; 28 percent on TND 20,001-30,000; 32 percent on TND 30,001-50,000; 35 percent above TND 50,000 [SC1]. The pre-reform progressive structure with multiple narrow bands was simplified under successive Loi de Finances amendments. Investment income (dividends from Tunisian companies) face 10 percent flat. Capital gains face specific rates with progressive holding-period reductions. Mandatory CNSS social security contributions apply at progressive rates (employee + employer).

How does Tunisia's corporate tax work?

The corporate income tax (Impot sur les Societes, IS) rate is 15 percent for fiscal years 2024 (raised to higher tier-rates under post-2025 successive amendments — Loi de Finances 2025 has progressively considered rate-restructuring with banking-sector elevated rates) [SC2]. Specific industry rates: financial sector elevated under successive amendments; oil/gas under specific Petroleum Code framework; export-oriented entities reduced rates under Code des Investissements 2017 framework. Withholding tax on dividends to non-residents is 10 percent (treaty rates apply). Pillar Two implementation pending. Tax loss carryforwards: 5 years (with depreciation indefinite-carryforward); carryback unavailable. Free Zones provide tax holidays for licensed export-manufacturing entities.

What about TVA (VAT)?

The standard VAT rate (Taxe sur la Valeur Ajoutee, TVA) is 19 percent under the Code de la TVA [SC3]. Reduced rates: 13 percent (specified categories) and 7 percent (basic foodstuffs, books, pharmaceutical, certain other essentials). Zero-rated supplies include exports. Registration threshold is TND 100,000 annual turnover. Reverse-charge mechanism applies on imported services. Foreign-supplier registration for B2C cross-border digital services applies under successive amendments.

How are cryptoassets taxed?

Tunisia has not enacted dedicated cryptoasset taxation. Banque Centrale de Tunisie (BCT) advisory positions cryptoassets as restricted [SC2]. Where declared, gains under existing income-tax categories at applicable rates. Mining and staking are business income at corporate rates. Dedicated CASP framework remains pending.

What is the treaty network and what are the audit triggers?

Tunisia has approximately 60 active double tax treaties [SC4]. Tunisia signed the OECD MLI on 24 January 2018 with successive ratification status. Audit triggers include disproportionate VAT credits, transfer-pricing non-compliance, undeclared bank deposits flagged via expanding CRS exchanges, and the e-Tax data reconciliation framework. Standard SOL is 4 years; extended for fraud or non-filing.

What are the common penalties and pitfalls for foreigners?

The Tunisian penalty framework imposes administrative-fine sanctions for late filings, failure to file, incorrect declarations (50-100 percent surcharge), and failure to maintain accounting records [SC5]. Default interest accrues at the prevailing rate plus statutory margin. Tax-evasion criminal exposure under specific provisions carries fines and imprisonment for grossly-significant evasion. Common foreign-national pitfalls: (1) the post-2024 PIT reform simplified the prior multi-band structure; (2) the centre-of-business-or-vital-interests test creates broad domiciliary-tax-attachment; (3) Pillar Two implementation pending; (4) Code des Investissements 2017 incentive frameworks have specific compliance requirements; (5) cross-border digital VAT framework progressively expanded; (6) the post-2024 IS rate-restructuring under successive Loi de Finances creates per-fiscal-year rate variation; (7) CNSS social security creates moderate payroll-cost burden; (8) MLI signed 2018; (9) Free Zones tax holidays have specific compliance requirements; (10) cryptocurrency activity remains restricted under BCT advisory.
