Republic of Senegal

Senegal operates a progressive tax system, with rates ranging from 0% to 43% based on an employee’s annual taxable income. Tax residents are taxed on their worldwide income, while non-residents are taxed only on income sourced within Senegal. The tax applies to various income sources, including salaries, wages, bonuses, allowances and benefits in kind, with certain deductions allowed for dependants and professional expenses. Taxable income is calculated after allowable deductions, including a standard professional expense deduction equal to 30% of gross employment income, subject to a monthly cap of XOF 75,000 (XOF 900,000 per year). The system applies a family quotient method, which splits taxable income into parts based on household size to apply progressive rates more equitably. A minimum personal income tax, known as the Minimum Personal Income Tax (MPIT) or Taxe Représentative de I’Impôt Minimum Fiscal (TRIMF), applies based on income bands. Employers are required to withhold income tax at source (retenue à la source) and remit it to the tax authorities. This tax is known as Impôt sur le Revenu des Personnes Physiques (IRPP), which represents the primary personal income tax collected on employment earnings.

Employers are responsible for withholding IRPP from employees’ salaries and remitting it to the Direction Générale des Impôts et des Domaines (DGID). In addition to income tax, payroll obligations include mandatory social security contributions shared between employers and employees. Employers must register with the Caisse de Sécurité Sociale (CSS) and the Institut de Prévoyance Retraite du Sénégal (IPRES) and make monthly contributions that fund statutory benefits such as family allowances, pensions, health insurance and workplace injury compensation. Employer contributions range from approximately 18% to 27% of gross salary, depending on sector and risk classification. This covers 7% for family benefits, 1% to 5% for workplace injury and occupational risk insurance, 8.4% for general pension, and 3.6% for the executive pension scheme, plus a 3% payroll tax known as Contribution Forfaitaire à la Charge de l’Employeur (CFCE). Employee contributions are generally lower and primarily relate to pension schemes. These include 5.6% for the general pension scheme and 2.4% for the executive pension plan, where applicable. CSS contributions are borne exclusively by the employer, while additional health coverage may be provided through employer-sponsored mutual schemes (Institution de Prévoyance Maladie – IPM), based on company size and collective agreements. These rates may be subject to monthly salary caps depending on the type of contribution.

Employers must comply with strict monthly and annual payroll tax reporting and payment deadlines. Each month, employers must withhold and remit IRPP to the DGID. Social security contributions must be remitted to CSS and IPRES, generally by the 15th of the following month through the respective online portals. Depending on employer size and classification, some social security declarations may be submitted monthly or quarterly, according to the applicable filing frequency. CSS contributions are reported monthly by employers with at least ten employees and quarterly by employers with fewer than ten employees. IPRES contributions are reported monthly by employers with at least 20 employees and quarterly by employers with fewer than 20 employees. Employers must also complete annual reporting obligations, which include summaries of wages paid and taxes withheld throughout the year, an annual CSS salary summary and an IPRES employee summary, confirming total contributions made per employee. The DGID annual salary and withholding statement (Déclaration Annuelle des Salaires – DAS) is ordinarily due by 31 January, subject to extensions announced by the DGID. The annual IPRES employee summary is due between 1 and 31 March of the following year. A separate annual CSS salary summary is also required, in accordance with the CSS filing timetable.

Employers in Senegal must comply with a range of labour and tax regulations, including proper registration with the DGID, CSS and IPRES. Employers and payroll providers must maintain comprehensive and accurate payroll records, including contracts, payslips and proof of social contributions, and make these available to inspections by CSS, IPRES or DGID. Under the Tax Code, documents recording salary payments and tax withholdings must be retained until the end of the eleventh year following the year in which the withholding occurred. Accounting records and supporting documents are generally retained for at least ten years, while employment contracts, payslips and other labour records are subject to their applicable statutory retention periods. Non-compliance can result in serious penalties: late or non-submitted returns may incur fixed fines, while late payments are subject to interest charges and surcharges. Underpaid or understated tax liabilities may attract penalties based on the severity of the non-compliance, with higher rates applied in cases involving deliberate misreporting or fraud.
