Net salary calculation Senegal: formula and 2026 example

A net salary calculation Senegal fits on one line: net pay = gross pay − employee contributions (IPRES pension and IPM health insurance) − income tax withheld at source − TRIMF. The difficulty lies in the details: contribution ceilings, a 30% allowance capped at 900,000 FCFA a year, an annual progressive tax scale and the number of tax shares. This guide sets out the rules that apply in 2026, the method step by step and a full worked example for a non-executive private-sector employee.

The net salary calculation Senegal formula in 2026

Only deductions borne by the employee reduce net pay. Employer contributions (CSS, the employer share of IPRES and IPM) and the employer flat-rate contribution (CFCE) increase the employer’s cost, not the amount paid to the employee.

Social rates and ceilings used for this net salary calculation Senegal: CLEISS, contributions at 1 January 2026. Tax rules: General Tax Code updated to January 2025, published by the tax authority (DGID).

Step 1 of a net salary calculation Senegal: start from the right gross

Gross pay includes base salary, supplements, bonuses (seniority, performance, gratuities), overtime and benefits in kind. It excludes expense reimbursements, listed in order n° 11719 of 17 December 2009: transport, mileage, meal (panier), travel, tool and soiling allowances. Family allowances are tax-exempt (art. 167 CGI).

Two rules from the national inter-professional collective agreement (CCNI) of 30 December 2019 come up often:

• Overtime (art. 49): a 15% premium for the first eight hours beyond the 40-hour legal week, 40% beyond that, 60% at night; on the weekly rest day and public holidays, 60% by day and 100% at night.
• Seniority bonus (art. 52): 2% of the category minimum wage after two years, plus 1% for each further year.
• A more favourable sector agreement or company agreement prevails over these rules.

Step 2 of a net salary calculation Senegal: deduct employee contributions

IPRES withholds 5.6% of gross pay up to 432,000 FCFA a month, so the deduction never exceeds 24,192 FCFA. Executives pay a further 2.4% to the supplementary scheme. For IPM, the rate depends on the institution the company belongs to, on a base capped at 250,000 FCFA. The CSS (social security fund for family benefits and work accidents) has no employee share.

Step 3: calculate income tax withheld at source

This is where a net salary calculation Senegal most often goes wrong, because the tax is computed on an annual basis.

The 30% flat allowance

Taxable net income is obtained after a 30% allowance that represents compulsory pension contributions and work expenses (art. 168 and 182 CGI), capped at 900,000 FCFA a year, or 75,000 FCFA a month. In practice, the IPRES contribution is not deducted a second time. Taxable income is rounded down to the nearest thousand francs.

The annual progressive scale

The family reduction

The tax from the scale is then reduced according to the number of shares (art. 174 CGI):

A single person without children has 1 share and a married person without children 1.5; each dependent child adds half a share, and a further half share applies when only one spouse has income. The total is capped at 5 shares and the situation at 1 January is used (art. 178). In monthly payroll, annualise the income, compute the year’s tax and divide by twelve. Withholdings are paid within the first fifteen days of the following month (art. 185).

Step 4: withhold the TRIMF

The TRIMF is a flat annual amount read from a table based on annual gross income: 900 FCFA up to 599,999 FCFA, 3,600 FCFA from 600,000 to 999,999, 4,800 FCFA from 1,000,000 to 1,999,999, 12,000 FCFA from 2,000,000 to 6,999,999, 18,000 FCFA from 7,000,000 to 11,999,999 and 36,000 FCFA above. The employee owes it for himself and for a spouse with no income (art. 276).

Worked net salary calculation Senegal: 450,000 FCFA gross

As an illustration, take a non-executive supervisor paid 450,000 FCFA gross a month, married with two dependent children and a spouse without income: 2.5 + 0.5 = 3 shares. We assume an employee IPM rate of 3%, to be replaced by your IPM’s actual rate.

The same salary for a single person without children gives annual tax of 1,099,000 FCFA, or 91,583 FCFA a month, and a TRIMF of 1,000 FCFA: net pay falls to 325,725 FCFA. Family situation alone moves net pay by 32,333 FCFA a month. Employer costs are detailed in our guide to social security contributions in Senegal.

Common mistakes in a net salary calculation Senegal

• Ignoring a ceiling: applying 5.6% to the full gross above 432,000 FCFA, or IPM above 250,000 FCFA.
• Deducting pension twice: removing IPRES from taxable income and then applying the 30% allowance, which already represents it.
• Not capping the allowance at 900,000 FCFA a year, which understates tax on every salary above 250,000 FCFA gross a month.
• Outdated tax shares: marriage, birth or a child over 25 not reported.
• A reduction larger than the tax: the minimum reduction cannot make tax negative.
• Taxing genuine expense reimbursements, or calling a bonus for work an expense allowance.
• Forgetting the TRIMF owed for a spouse without income.

Special cases in a net salary calculation Senegal

• Executives: add the 2.4% employee share of the IPRES supplementary scheme and ask IPRES to confirm the exact base applied to your staff.
• Employees on the minimum wage: at 64,223 FCFA gross a month, taxable income stays below 630,000 FCFA a year and income tax is zero; see our article on the minimum wage in Senegal.
• Annual bonus or thirteenth month: recompute annualised tax in the month of payment to avoid under-withholding.
• Severance pay: exempt from income tax when determined in line with labour law (art. 167); see our guide to severance pay in Senegal.
• Health insurance: contributions are exempt up to 10% of gross salary income (art. 167, point 15); agree the payroll treatment with your adviser.
• Non-residents: 1.5 shares at most (art. 176).

Automating the calculation and the payslip

By hand, a single ceiling error repeats every month. Socium’s free payroll simulators, including a gross-to-net simulator for Senegal announced in the resources area, give an order of magnitude. In production, Socium’s payroll software for Senegal applies this net salary calculation Senegal to every employee, produces the electronic payslip and prepares the returns.

Frequently asked questions

What is the employee deduction rate in Senegal?

For a non-executive, 5.6% for IPRES (on up to 432,000 FCFA) plus the IPM share, between 2% and 7.5% on up to 250,000 FCFA. Income tax and TRIMF come on top, depending on pay and family situation.

How does a net salary calculation Senegal work for an executive?

The method is the same, with an additional 2.4% to the executives’ supplementary scheme and, usually, a 30% allowance already capped at 900,000 FCFA. The marginal tax rate is generally higher.

Does the new Labour Code change the net salary calculation Senegal?

Law n° 2026-18 on the Labour Code changes neither contribution rates nor the tax scale. It does require payment no later than eight days after the end of the month (art. 199) and a payslip for every payment (art. 202).

Is net pay the same every month?

No, as soon as overtime, unpaid absence or a bonus changes gross pay. The calculation is redone at each payroll run.

Key takeaways

• Net = gross − IPRES (5.6% on up to 432,000 FCFA) − IPM − income tax − TRIMF.
• Income tax is computed annually: 30% allowance capped at 900,000 FCFA, a 0% to 43% scale, then a reduction based on shares.
• In any net salary calculation Senegal, family situation matters: over 32,000 FCFA a month on a 450,000 FCFA gross in our example.
• Reliable results depend on up-to-date shares, applied ceilings and correctly classified expenses.
