NSSF 10/10 on gross. SDL + WCF employer levies. Tanzania payroll, solved.
Tanzania’s payroll is not a configuration exercise. It demands the NSSF 20% pension contribution run on the correct 10% employer / 10% employee split on uncapped gross, the Skills & Development Levy at 3.5% for employers of ten or more, the Workers Compensation Fund at 0.5%, and progressive PAYE from 0% to 30% withheld on income net of NSSF – with non-residents on a flat 15% final tax. Most providers model the headline rate and miss the rest. Mercans delivers all of them – on a single proprietary stack with no intermediaries.

Getting Tanzania payroll “mostly right” is the most expensive mistake
Tanzania’s regulators don’t grade on a curve. The TRA holds employers strictly liable for under-withheld PAYE, the SDL, and late remittances. The NSSF reconciles the 20% contribution against gross pay and assesses retroactively when the split or base is wrong. The WCF expects its 0.5% tariff on cash sums paid, and labour inspectors enforce the Employment and Labour Relations Act on leave, notice, and severance. None of these failures announce themselves – they accumulate silently until an audit makes them very visible.
NSSF 20% split & remittance errors
NSSF is 20% of gross – standard split 10% employer + 10% employee, with the employee share capped at 10% (the employer may absorb the whole 20%). It applies to gross pay with no ceiling, and contributions must reach the Fund within one month of the month-end. Wrong split, a missed base, or late payment triggers retroactive NSSF assessment plus penalties.
SDL 3.5% employer levy miscalculated or missed
The Skills and Development Levy is 3.5% of gross cash emoluments, borne entirely by the employer, and is due for any employer with ten or more employees – remitted to the TRA by the 7th of the following month. It is a payroll tax, not a social contribution, so it is easy to omit from cost models and reconciliations, exposing the employer to TRA penalties and interest.
PAYE bands & non-resident 15% mishandled
Resident PAYE runs five monthly bands from 0% (up to TZS 270,000) to 30% (above TZS 1,000,000), computed on gross pay net of the employee NSSF contribution. Non-residents are taxed at a flat 15%, which is a final tax. Applying the wrong base, the wrong band, or the resident scale to a non-resident distorts withholding on every payslip.
WCF tariff & ELRA entitlements overlooked
The Workers Compensation Fund tariff is 0.5% of cash sums paid for private-sector employers. Alongside it, the Employment and Labour Relations Act mandates 28 days’ annual leave, 28 days’ notice for monthly-paid staff, severance of 7 days’ basic wage per completed year, and 126 days’ sick leave (63 full / 63 half). Missing any of these triggers labour-inspection findings and back-pay.
The three types of providers who struggle with Tanzania
Global Aggregator Platforms
Aggregator platforms operate through a partner network in Tanzania – they don’t own the entity, don’t directly file with the TRA, NSSF, or WCF, and don’t control the compliance relationship. When PAYE bands, the SDL rate, or NSSF rules change, the instruction travels: platform → partner → your payroll. Each handoff introduces delay and interpretation risk.
- ×No direct TRA / NSSF / WCF filing – partner bureau handles returns
- ×NSSF 10/10 split and uncapped base partner-dependent
- ×SDL 3.5% (10+ employees) often excluded from cost quotes
- ×Non-resident 15% final tax logic typically simplified or wrong
Large Global Payroll Incumbents
Incumbents have Tanzania coverage – in name. In practice, their East Africa coverage is often delivered through regional partners or legacy systems not built for Tanzania’s NSSF 20% split, the SDL and WCF employer levies, the PAYE-on-net-of-NSSF base, or the non-resident final tax.
- ×PAYE base net of NSSF hardcoded – not dynamic
- ×SDL / WCF employer levies handled manually per run
- ×No severance scenario engine for ELRA seniority bands
- ×Long implementation timelines – Tanzania not a core market
Local Tanzanian Firms
Local Tanzanian accounting and bookkeeping 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 Tanzania + other entities
The only provider that closes every gap
Mercans is the only Tanzania payroll provider that combines a proprietary payroll technology stack, full-time in-country compliance teams, direct TRA, NSSF, and WCF relationships, and enterprise-grade data security – simultaneously, on one contract, with no intermediaries.
The only engine built for Tanzania’s actual payroll architecture
G2N Nova™ is the world’s only API-first gross-to-net payroll engine. It natively models Tanzania’s statutory stack as distinct calculation layers – NSSF 20% on the 10/10 split over uncapped gross, the SDL 3.5% employer levy for employers of ten or more, the WCF 0.5% tariff, progressive PAYE from 0% to 30% on income net of NSSF, and the non-resident 15% final tax. This isn’t configuration. It’s engineering.
Full-time Tanzania team – not a partner you phone when things break
Mercans employs full-time payroll and compliance professionals in Tanzania. They maintain active relationships with the Tanzania Revenue Authority, the NSSF, and the Workers Compensation Fund – not through a contact directory, but through ongoing regulatory engagement. When the TRA revises the PAYE bands, when the NSSF updates a contribution rule, when the WCF adjusts its tariff – we know before it reaches your inbox.
The security posture multinationals require – and Tanzania’s PDPA now mandates
Tanzania’s Personal Data Protection Act, 2022 (Act No. 11 of 2022) places obligations on payroll processors handling employee data (NSSF/WCF numbers, TIN, salary records) under the supervision of the Personal Data Protection Commission (PDPC), with mandatory registration of data controllers and processors. Mercans holds BCR approval, ISO 27701 certification, SOC 1 & 2 certifications, and ISO 27017/27018. Zero security breaches since inception.

NSSF pension is 20% of gross salary. The standard split is 10% employer + 10% employee, with the employee share capped at 10% – the employer may elect to absorb the full 20%. It applies to gross pay with no ceiling and must reach the Fund within one month of the month-end. Mercans’ G2N Nova™ applies the split on the correct base – not as a single hardcoded line.

G2N Nova™ engineEight things only Tanzania experts know to handle
These are the compliance details that don’t appear in standard payroll setup guides – but appear in every TRA audit, NSSF reconciliation, WCF inspection, and labour dispute we’ve encountered in Tanzania over 20 years.
NSSF Is 20% of Gross on a 10 / 10 Split
Every registered employer remits 20% of the employee’s gross salary to the NSSF – standard split 10% employer + 10% employee, with the employee share capped at 10% (an employer may absorb the whole 20%). It applies to gross pay with no ceiling. Getting the split or base wrong is the single most common Tanzania NSSF error.
SDL Is a 3.5% Employer Levy Above 10 Employees
The Skills and Development Levy is 3.5% of gross cash emoluments, borne entirely by the employer, and is payable by any employer with ten or more employees. It is remitted to the TRA by the 7th of the following month. It is a payroll tax, not a social contribution – so it is easy to omit from cost-of-employment models.
WCF Tariff Is 0.5% for the Private Sector
The Workers Compensation Fund tariff on private-sector employers is 0.5% of the cash sums paid to employees (reduced from 1%). It funds work-injury and occupational-disease cover, is entirely employer-funded, and is declared and paid monthly. Applying the wrong tariff or base under- or over-contributes.
PAYE Runs Five Monthly Bands from 0% to 30%
Resident PAYE on monthly income: 0% up to TZS 270,000; 8% (270,001–520,000); 20,000 + 20% (520,001–760,000); 68,000 + 25% (760,001–1,000,000); 128,000 + 30% above 1,000,000. The base is gross pay net of the employee NSSF contribution – not gross itself.
Non-Residents Pay a Flat 15% Final Tax
Employment income of non-resident individuals is taxed at a flat 15%, which is a final tax in Tanzania – the progressive resident scale does not apply, and no further return is required from the employee. Misclassifying residence, or applying the resident bands, produces incorrect withholding and reconciliation gaps.
Sick Leave Is 126 Days – 63 Full, 63 Half
Under the Employment and Labour Relations Act, an employee is entitled to 126 days’ sick leave in any 36-month leave cycle: the first 63 days at full wages and the next 63 days at half wages, subject to a medical certificate. The split must be tracked per employee across the cycle, not reset each calendar year.
Severance Is 7 Days’ Wage Per Year, Capped at 10
Severance pay is at least 7 days’ basic wage for each completed year of service, up to a maximum of ten years, for employees with at least one year of service. Notice is 28 days for monthly-paid staff. Severance is not due on fair dismissal for misconduct, on retirement, or on natural expiry of a fixed-term contract.
TRA + NSSF + WCF on a Tight Monthly Cycle
PAYE and the SDL are remitted to the TRA by the 7th of the following month. NSSF contributions are due within one month of the month-end; WCF is declared monthly. Corporate provisional tax is filed quarterly and the final return within six months of year-end. Missed deadlines trigger penalties and interest.
One workforce. Two entirely different compliance tracks.
Resident Tanzanian employees on full NSSF, progressive PAYE, and the SDL/WCF employer charges vs. non-resident and expatriate employees on the 15% final tax and permit obligations – two distinct compliance tracks that must run simultaneously on every pay cycle.
Parallel Compliance Engines
(Tanzanian Nationals)
NSSF pension on the 10 / 10 split, uncapped. 20% of gross salary – 10% employer + 10% employee (employer may absorb the full 20%) – on gross pay with no ceiling. Declared and paid to the NSSF within one month of the month-end.
PAYE withheld monthly on the progressive scale. Five bands from 0% (up to TZS 270,000) to 30% (above 1,000,000), computed on gross pay net of the employee NSSF contribution. Remitted to the TRA by the 7th of the following month.
SDL and WCF are employer-funded charges. SDL 3.5% of gross emoluments where ten or more are employed, plus the WCF 0.5% tariff on cash sums paid. Both are borne entirely by the employer and remitted separately from NSSF.
Labour entitlements under the ELRA. 28 days’ paid annual leave; 28 days’ notice for monthly-paid staff; severance of 7 days’ wage per year (max 10); 126 days’ sick leave at 63 full / 63 half; overtime at 150%.
(Work Permit Holders)
Employment income taxed at a flat 15% final tax. The progressive resident scale does not apply; 15% is a final tax on Tanzania-source employment income. No further individual return is required once the tax is withheld and remitted.
NSSF & WCF enrolment unless an exemption applies. Absent an applicable social-security arrangement, expatriate employees on a Tanzanian payroll are enrolled in the NSSF (20%) and WCF (0.5%) on the same basis as residents. Any exemption must be documented.
SDL applies to expatriate remuneration. The 3.5% SDL employer levy applies to expatriate cash emoluments once the employer meets the ten-employee threshold, on the same basis as for resident staff.
Work and residence permit requirements. Foreign employees require a work permit (Ministry of Labour) and residence permit (Immigration). Standard withholding and contribution obligations apply identically once the employee is enrolled.
Every obligation. Every authority. Mercans owns the calendar.
Tanzania compliance runs across the TRA, NSSF, and WCF on monthly, quarterly, and annual cadences. Mercans’ managed payroll absorbs every filing as standard scope – you don’t track deadlines. We do.
PAYE Withholding Return
Pay-as-you-earn income tax withheld on employment income is remitted to the TRA by the 7th of the following month. Resident PAYE is computed on the progressive 0–30% monthly bands on gross pay net of NSSF; non-resident income is withheld at a flat 15% final tax.
Skills & Development Levy (SDL)
The SDL, 3.5% of gross cash emoluments for employers of ten or more, is declared and paid to the TRA by the 7th of the following month. It is a fiscal charge borne entirely by the employer, separate from the NSSF and WCF social contributions.
NSSF Contribution Declaration
NSSF pension contributions – 20% of gross on the 10% employer / 10% employee split, uncapped – are declared and paid to the National Social Security Fund within one month of the end of the month to which they relate.
WCF Contribution Declaration
The Workers Compensation Fund tariff, 0.5% of cash sums paid for private-sector employers, is declared and paid to the WCF on its monthly schedule. It funds work-injury and occupational-disease cover and is entirely employer-funded.
Provisional Income Tax
A statement of estimated income tax payable is due within three months of the start of the accounting period, with instalments paid quarterly. It reconciles against the final return and must reflect projected profits for the year.
Final Corporate Income Tax Return
The final income tax return must be furnished within six months of the end of the accounting period (nine months for public-sector entities). Corporate income tax is 30%; discrepancies against provisional filings trigger a TRA review.
NSSF / WCF Registration
New employees must be registered with the NSSF and WCF before their first declaration; departures must be reported. Late or missing registration blocks the employee’s pension and injury-cover entitlements and exposes the employer to penalties.
Severance & Final Settlement
Final settlement applying severance of 7 days’ basic wage per completed year (max ten) for staff with a year’s service, plus 28 days’ notice for monthly-paid employees and accrued unused leave, under the Employment and Labour Relations Act.
