One global CNSS rate. 8-bracket IRPP + CSS. Tunisia payroll, solved.
Tunisia’s payroll is not a configuration exercise. It runs on one global CNSS régime général rate – 17.07% employer + 9.68% employee, uncapped – that bundles CNAM health and the new 0.5% unemployment fund, plus a progressive 8-bracket IRPP (0–40%) with the 10% professional abatement and family deductions, the 0.5% CSS solidarity levy, and the TFP + FOPROLOS employer taxes. Most providers model the headline CNSS rate and miss the rest. Mercans delivers all of them – on a single proprietary stack with no intermediaries.

Getting Tunisia payroll “mostly right” is the most expensive mistake
Tunisia’s regulators don’t grade on a curve. The CNSS holds employers strictly liable for under-declared salaries on the uncapped régime général. The DGI reconciles monthly IRPP retenues against the annual employer declaration and reassesses when the new 8-bracket scale or the deductions are applied wrongly. The CSS solidarity levy and the TFP + FOPROLOS employer taxes are easy to miss because they sit outside the headline CNSS line. None of these failures announce themselves – they accumulate silently until an inspection makes them very visible.
CNSS régime général salaries under-declared
CNSS is one global rate – 17.07% employer + 9.68% employee – on uncapped gross pay, bundling pension, CNAM health, family benefits, and the new 0.5% unemployment fund. Declaring an incomplete base, or treating CNAM as a separate bill, produces retroactive CNSS assessments with surcharges and blocks employee entitlements.
New 8-bracket IRPP scale & deductions mis-applied
The Finance Law 2025 replaced the old 5-bracket scale with eight brackets from 0% (≤ TND 5,000) to 40% (> TND 70,000). Taxable pay is gross minus 9.68% CNSS, the 10% professional abatement (capped TND 2,000/yr), and family deductions. Wrong brackets or deductions distort the retenue à la source on every payslip.
CSS solidarity contribution omitted
The Contribution Sociale de Solidarité is withheld at 0.5% of taxable income for fiscal years 2023–2026 (rising to 1% from 2027), on top of IRPP, with an exemption for salary income not exceeding TND 5,000/yr. It is a separate line from IRPP and easy to drop – omitting it under-withholds and exposes the employer on reconciliation.
TFP + FOPROLOS employer levies missed
The vocational-training tax (TFP, 2% of gross payroll; 1% for manufacturing) and the social-housing levy (FOPROLOS, 1%) are employer-only fiscal charges remitted to the DGI, alongside the work-accident contribution (0.4–4% by risk class). They are uncapped and sit outside CNSS – omitting them understates the true cost of employment and triggers DGI penalties.
The three types of providers who struggle with Tunisia
Global Aggregator Platforms
Aggregator platforms operate through a partner network in Tunisia – they don’t own the entity, don’t directly file with the DGI, CNSS, or CNAM, and don’t control the compliance relationship. When the CNSS rate or the IRPP brackets change, the instruction travels: platform → partner → your payroll. Each handoff introduces delay and interpretation risk.
- ×No direct DGI / CNSS / CNAM filing – partner bureau handles declarations
- ×New 8-bracket IRPP scale & deductions typically simplified or wrong
- ×CSS 0.5% solidarity levy often dropped from withholding
- ×TFP 2% + FOPROLOS 1% employer levies excluded from cost quotes
Large Global Payroll Incumbents
Incumbents have Tunisia coverage – in name. In practice, their North-Africa coverage is often delivered through regional partners or legacy systems not built for the uncapped CNSS global rate, the CNAM health branch inside it, the revised 0–40% IRPP scale, or the CSS + TFP + FOPROLOS layers.
- ×CNSS global rate hardcoded – CNAM branch not modelled inside it
- ×IRPP 8-bracket scale reconfigured by hand each change
- ×10% abatement & family deductions handled manually
- ×Long implementation timelines – Tunisia not a core market
Local Tunisian Firms
Local Tunisian fiduciaires and accounting firms know the market – but they can’t scale with you. No proprietary payroll technology platform, no HRIS integration, no multi-country consolidation, and no data security certifications that multinationals require. Fine for 10 employees. Inadequate at 100.
- ×No proprietary payroll technology – manual spreadsheet-based processing
- ×No HCM connector – Workday, SAP, Oracle feeds require custom work
- ×No data security certifications (SOC 1/2, ISO 27701, BCR)
- ×No Africa consolidation – cannot report across Tunisia + other entities
The only provider that closes every gap
Mercans is the only Tunisia payroll provider that combines a proprietary payroll technology stack, full-time in-country compliance teams, direct DGI, CNSS, and CNAM relationships, and enterprise-grade data security – simultaneously, on one contract, with no intermediaries.
The only engine built for Tunisia’s actual payroll architecture
G2N Nova™ is the world’s only API-first gross-to-net payroll engine. It natively models Tunisia’s structure as distinct calculation layers – the uncapped CNSS régime général (17.07% ER + 9.68% EE) with the CNAM health branch inside it, the progressive 8-bracket IRPP (0–40%) after the 10% abatement and family deductions, the 0.5% CSS solidarity levy, and the TFP + FOPROLOS employer taxes. This isn’t configuration. It’s engineering.
Full-time Tunisia team – not a partner you phone when things break
Mercans employs full-time payroll and compliance professionals in Tunisia. They maintain active relationships with the DGI, the CNSS, and the CNAM – not through a contact directory, but through ongoing regulatory engagement. When the Finance Law revises the IRPP brackets, when the CNSS rate moves, when the CNAM updates a benefit rule – we know before it reaches your inbox.
The security posture multinationals require – and Tunisia’s Loi 2004-63 now mandates
Tunisia’s Loi organique n° 2004-63 on the protection of personal data places obligations on payroll processors handling employee data (CNSS/CNAM numbers, salary records) under the supervision of the Instance Nationale de Protection des Données Personnelles (INPDP). Mercans holds BCR approval, ISO 27701 certification, SOC 1 & 2 certifications, and ISO 27017/27018. Zero security breaches since inception.

The régime général is 17.07% employer + 9.68% employee (26.75% combined) on uncapped gross salary, covering pension, CNAM health, family benefits, and the 0.5% unemployment fund introduced in 2025. There is no salary ceiling and CNAM is collected inside the rate. Mercans’ G2N Nova™ applies the global rate on the full base – not as hardcoded caps.

G2N Nova™ engineEight things only Tunisia experts know to handle
These are the compliance details that don’t appear in standard payroll setup guides – but appear in every DGI audit, CNSS reconciliation, CNAM review, and labour dispute we’ve encountered in Tunisia over 20 years.
CNSS Is One Global, Uncapped Régime Général Rate
The régime général is a single global rate – 17.07% employer + 9.68% employee – applied to uncapped gross salary. It bundles pension, CNAM health, family benefits, and the new 0.5% unemployment fund. There is no salary ceiling, so contributions rise linearly with pay – unlike the capped systems elsewhere in the region.
CNAM Health Sits Inside the CNSS Rate
Health insurance is administered by the CNAM but collected inside the CNSS global rate – it is not a separate employer bill. Short-term sickness benefits run at 66.7% of the average daily wage after a 5-day waiting period, for up to 180 days a year. Treating CNAM as a standalone premium double-counts or under-funds cover.
The IRPP Scale Was Rebuilt to Eight Brackets (LF2025)
The Finance Law 2025 replaced the old 5-bracket scale (35% top) with eight brackets on annual income: 0% ≤ 5,000; 15% (5,000–10,000); 25% (10,000–20,000); 30% (20,000–30,000); 33% (30,000–40,000); 36% (40,000–50,000); 38% (50,000–70,000); 40% above 70,000. It applies to 2025 income onward.
Taxable Pay Is Gross Minus CNSS, Abatement & Family Deductions
The IRPP base is gross salary minus the 9.68% CNSS employee share, minus a 10% professional-expenses abatement (capped at TND 2,000/yr), minus family deductions – head of family TND 300, and TND 100 per dependent child up to four. Getting the base wrong is the most common Tunisia withholding error.
CSS Solidarity Levy Is Separate from IRPP
The Contribution Sociale de Solidarité is withheld at 0.5% of taxable income for fiscal years 2023–2026, rising to 1% from 1 January 2027, on top of the IRPP. Salary income not exceeding TND 5,000/yr is exempt. It is a distinct line – omitting it under-withholds on the majority of payslips.
TFP and FOPROLOS Are Employer Payroll Taxes
The vocational-training tax (TFP) is 2% of gross payroll – 1% for manufacturing industries – and the social-housing levy (FOPROLOS) is 1%, both borne entirely by the employer and remitted to the DGI. They are uncapped fiscal charges, separate from CNSS, and easy to leave out of cost-of-employment models.
SMIG Splits by 48h / 40h and Overtime by Regime
The 2026 SMIG (décret 2026-67) is TND 554.736/month on the 48-hour regime and TND 470.251/month on the 40-hour regime. Overtime is paid at +75% on the 48-hour regime; on a sub-48-hour regime it is +25% up to 48 hours and +50% beyond, and +50% for part-time work.
DGI + CNSS Filing on a Tight Monthly/Quarterly Cycle
IRPP and CSS withheld (retenues) are remitted to the DGI monthly; the CNSS contribution declaration and payment are due by the 15th of the month following each quarter. An annual employer declaration (déclaration de l’employeur) reconciles the year. Missed deadlines trigger surcharges and late-payment penalties.
One workforce. Two entirely different compliance tracks.
Tunisian national employees on full CNSS, CNAM, progressive IRPP, and CSS obligations vs. expatriate employees on Tunisia-source income withholding and totalization-treaty considerations – two distinct compliance tracks that must run simultaneously on every pay cycle.
Parallel Compliance Engines
(Resident Employees)
CNSS régime général on uncapped gross. 17.07% employer + 9.68% employee, bundling pension, CNAM health, family benefits, and the 0.5% unemployment fund. No salary ceiling. Declared to the CNSS each quarter.
IRPP withheld monthly on the 8-bracket scale. Progressive 0–40% on income after 9.68% CNSS, the 10% professional abatement (cap TND 2,000), and family deductions, plus the 0.5% CSS solidarity levy. Remitted to the DGI monthly.
Employer levies TFP + FOPROLOS + work-accident. TFP 2% (1% manufacturing) and FOPROLOS 1% of gross payroll to the DGI, plus the work-accident contribution 0.4–4% by risk class. All employer-borne and uncapped.
Labour entitlements under the Code du Travail. SMIG TND 554.736/mo (48h); leave one working day per month (12–18/yr); notice one month for workers, three for cadres; severance one day’s pay per month of service, max three months.
(Work & Residence Permit)
Tunisia-source income tax at progressive 0–40%. Same IRPP brackets and deductions as nationals. Taxable on Tunisia-source employment income regardless of where salary is paid. DTA relief follows the applicable treaty and DGI procedure.
CNSS enrolment unless a totalization treaty applies. Without an applicable social-security agreement, expatriate employees are enrolled in the CNSS on the same uncapped rate as nationals. Treaty coverage must be documented to claim relief.
CSS and employer levies apply identically. The 0.5% CSS solidarity levy, TFP 2%, and FOPROLOS 1% apply to expatriate remuneration on the same basis once the employee is on a Tunisian payroll.
Work and residence permit requirements. Foreign employees require a work contract endorsed by the labour authority and a valid residence card. Standard IRPP and contribution obligations apply identically once enrolled.
Every obligation. Every authority. Mercans owns the calendar.
Tunisia compliance runs across the DGI, CNSS, and CNAM on monthly, quarterly, and annual cadences. Mercans’ managed payroll absorbs every filing as standard scope – you don’t track deadlines. We do.
CNSS Contribution Declaration
The régime général contribution – 17.07% employer + 9.68% employee on uncapped gross – is declared and paid to the CNSS by the 15th of the month following each quarter (larger employers file monthly). It bundles pension, CNAM health, family benefits, and the 0.5% unemployment fund.
IRPP & CSS Withholding (Retenue à la Source)
Income tax withheld on the 8-bracket 0–40% scale after the 9.68% CNSS, the 10% abatement, and family deductions, plus the 0.5% CSS solidarity levy, is remitted to the DGI monthly. The base and brackets must match the Finance Law 2025 scale exactly.
TFP + FOPROLOS Employer Taxes
The vocational-training tax (TFP, 2% of gross payroll; 1% for manufacturing) and the social-housing levy (FOPROLOS, 1%) are declared and paid to the DGI. Both are employer-only, uncapped fiscal charges, separate from the CNSS social contributions.
CNAM Health & Sick-Leave Management
Health cover is administered by the CNAM within the CNSS rate. Short-term sickness benefits run at 66.7% of the average daily wage after a 5-day waiting period, for up to 180 days a year. Continuous tracking is required for handoff to the fund and for maternity and long-term cases.
Annual Employer Declaration (DE)
The employer’s annual declaration reconciles all remuneration, withheld IRPP and CSS, and contributions per employee against the monthly retenue and CNSS filings. Filed with the DGI early in the following year; discrepancies trigger audit and reassessment.
Corporate Income Tax (IS) Return
The annual IS return applies the 20% standard rate (10% / 35% / 40% for specific sectors) with a minimum tax of 0.2% of local turnover (min TND 500). Reconciled against advance instalments; discrepancies trigger a DGI review.
CNSS Affiliation / Immatriculation
New employees must be affiliated with the CNSS before their first declaration; departures must be reported. Late or missing affiliation blocks the employee’s social and CNAM entitlements and exposes the employer to penalties.
Severance & Notice Settlement
Final settlement applying the statutory indemnité de licenciement – one day’s wage per month of service, capped at three months (collective agreements may exceed) – plus notice of one month for workers or three months for cadres, and accrued unused leave.
