The net global income serving as the basis of the PIT shall be composed of the excess of the gross yield, including the value of the profits and benefits in kind, over the charges and expenses paid out in view of the acquisition and conservation of the income.
The net global revenue shall be composed of the total amount of the net income determined separately in accordance to the rules proper to each of the following categories of income:
- Industrial and commercial profits.
- Profits from non-commercial professions.
- Profits from agricultural or fishing activities.
- Wages, salaries, indemnities, pensions, and annuities.
- Real estate income.
- Income from securities and investments.
- Foreign-sourced income.
PIT is due by all individuals considered as tax resident in Tunisia on the basis of their worldwide income (including foreign-sourced income, except those already subject to tax abroad).
For non-Tunisian tax resident individuals, Tunisian-sourced income realised by non-resident employees is subject to income tax in Tunisia, in general, through a withholding tax (WHT) to be applied by the Tunisian established debtor.
The WHT rates depend on the nature of income as well as the existence of a double taxation treaty (DTT) between Tunisia and the state of residence of the individual.
For salaries, the net income is calculated as the gross salary reduced by the mandatory social security contributions paid to Tunisian social security organisations and 10% on the amount net of Tunisian social security contributions as deduction for professional expenses, capped at TND 2,000.
The gross salary includes the value of benefits in kind (e.g. lodging, car, transportation, meals, school expenses, medical expenses). Benefits in kind are valued at their actual value.
For salaries, income tax is to be withheld at source by the employer (or the employee in the particular case of expatriates earning salaries from outside Tunisia for work done in Tunisia) on a monthly basis. The monthly income tax is calculated as 1/12 of the annual income tax determined according to the progressive scale below.
However, the income tax may be due at a flat rate of 20% of their gross income, before deductions for any reason whatsoever (including compulsory social security contributions for the establishment of their retirement pensions), for:
- Non-resident employees working in Tunisia for a period or periods not exceeding six months per fiscal year.
- Certain employees of foreign nationality (managers and trainers) employed by:
- Totally exporting companies.
- Oil and gas companies governed by the Decree-Law n°85-9, if the concerned employees’ work is related to exploration.
- Oil and gas companies governed by the Hydrocarbon Code promulgated by the Law n° 99-93, whether the personnel carries out activities related to exploration or production.
- Companies based in Free Trade Zones as defined by the Law n° 92-81.
- Financial institutions working mainly with non-Tunisian residents, governed by the Code for financial services provided for non-residents.
Personal income tax rates
Except in cases where the option to pay the income tax at a flat rate is possible (see above), income tax is calculated according to the following progressive scale:
|Taxable income (TND)
||Effective rate on limit (%)
Note that revenues derived from activities that are subject to CIT at the reduced rate of 10% are 2/3 deductible from the taxable income.
Note that revenues derived from activities that are subject to CIT at the reduced rate of 13.5% (applicable from 2021 for listed activities) are 1/2 deductible from the PITable income.
The Finance Law 2018 implemented a social solidarity contribution to the benefit of the social funds, which is due by individuals (resident or not resident in Tunisia) on their income taxable in Tunisia and in application of the PIT scale. Hence, that contribution is not applicable to the income that is not taxable in application of the PIT scale, including mainly dividends, capital gains, and salary income taxable at the flat rate of 20% since these income categories are taxable at a specific PIT rate and not subject to the PIT scale. Also, income exempted from PIT will not be subject to the said contribution. The solidarity contribution is due at the rate of 1%. It is applicable from 1 January 2018.
The financial Law 2020 provided that individuals realising exclusively salaries, wages, pensions and life annuities and whose annual net income does not exceed 5,000 dinars are exempted from the said social solidarity contribution as from January 1, 2020.
Hence, the PIT scale will be as follows:
|Taxable income (TND)
||PIT rate excluding the solidarity contribution (%)
||PIT rate including the solidarity contribution (%)
|From 0 to 5,000
|From 5,000 to 20,000
|From 20,000 to 30,000
|From 30,000 to 50,000
(*) The social solidarity contribution rate of 0% will apply as from January 1, 2020 only for individuals realising exclusively salaries, wages, pensions and life annuities and whose annual net income does not exceed 5,000 dinars.
