Section 2 -- Income Tax Withholding (PAYE — Pay-As-You-Earn)

Rwanda does levy personal income tax on employees. The employer is the withholding agent: it deducts PAYE monthly from payroll and remits it monthly to RRA by the 15th of the following month (PwC — Tax administration). The brackets are expressed on MONTHLY taxable employment income in RWF and were set by Law No. 027/2022 of 20/10/2022, with the bracket structure fully phased in from November 2023 (PwC, last reviewed 18 Feb 2026; RRA calculation guide).

PAYE Progressive Table — Monthly Taxable Income (2025, CONFIRMED)

PAYE Progressive Table — Monthly Taxable Income (2025, CONFIRMED) (Source: RRA calculation guide (Law 027/2022, monthly bands, raised 0% threshold); PwC — Taxes on personal income.)

Monthly taxable income (RWF)	Marginal rate	Tax on this bracket (cumulative at top)
0 – 60,000	0%	Frw 0
60,001 – 100,000	10%	Frw 4,000
100,001 – 200,000	20%	Frw 24,000
200,001 and above	30%	—

• Residency scope — Same rates apply to residents and non-residents (PwC)
• Local taxes — No local / municipal income taxes in Rwanda (PwC)
• 0% threshold history — The 0% threshold (first Frw 60,000/month) was raised from the prior Frw 30,000 when Law 027/2022 took effect (RRA)

Subtract-method constants (2025) (monthly tax = (monthly taxable income × rate) − subtract)

Band (RWF)	Rate	Subtract (RWF)
60,001 – 100,000	10%	6,000
100,001 – 200,000	20%	16,000
200,001+	30%	36,000

Continuity check:

• At 100,000 → 0.10 × 100,000 − 6,000 = Frw 4,000 (= cumulative band tax). Tie out.
• At 200,000 → 0.20 × 200,000 − 16,000 = Frw 24,000. Tie out.
• Band entry at 200,001 → 0.30 × 200,001 − 36,000 = Frw 24,000.30 ≈ continuous with Frw 24,000. Tie out.

Casual labour rate

Casual labour rate

Item	Detail	Source
Casual labourer engaged < 30 days in a tax year	Employer withholds a flat 15% of taxable employment income	RRA calculation guide
Tax-free portion for casual labour	Secondary sources conflict (Frw 30,000 older vs Frw 60,000 aligned to general threshold). The 15% flat rate is authoritative; the exact tax-free slice is [RESEARCH GAP — reviewer to confirm against current RRA casual-labour rules]	RRA

Withholding mechanism

• PAYE withholding cadence — PAYE is withheld monthly by the employer from payroll and remitted monthly to RRA by the 15th (PwC)
• Annual return exemption — Individuals earning only employment income are exempt from filing an annual return — PAYE is final. Those with additional income types must file by 31 March. (PwC — Tax administration)

Section 3 -- RSSB Pension Scheme (Employee + Employer)

All persons working in Rwanda (nationals and foreigners) must contribute to RSSB-managed schemes. The employer deducts, declares and pays both employer and employee shares (RRA — RSSB declaration).

MAJOR 2025 CHANGE: the pension rate doubled from 6% to 12% effective 1 January 2025, split equally employer/employee, with phased increases to 20% by 2030 (PwC — Other taxes; VisionsAfrica advisory). The contribution base was expanded in 2025 to include the transport allowance (previously excluded) (VisionsAfrica).

Pension Contribution Schedule (basis: gross salary)

Pension Contribution Schedule (basis: gross salary) (Source: PwC — Other taxes (full schedule, splits, basis); VisionsAfrica (2025 base now includes transport).)

Effective	Total	Employer	Employee
From 1 Jan 2025	12%	6%	6%
From 1 Jan 2027	14%	7%	7%
From 1 Jan 2028	16%	8%	8%
From 1 Jan 2029	18%	9%	9%
From 1 Jan 2030	20%	10%	10%

• Prior rate — Prior rate (through 2024) was 6% total / 3% each (PwC)
• Salary ceiling — No salary ceiling/cap on pension was found in authoritative sources — contributions appear uncapped (percentage of full gross). [RESEARCH GAP — reviewer to confirm absence of a ceiling with RSSB].

Column check (2025): employer 6% + employee 6% = 12% total. Tie out.

Section 4 -- RSSB Occupational Hazards Scheme

Occupational Hazards Scheme (PwC — Other taxes)

Item	Total	Employer	Employee	Basis	Source
Occupational hazards	2%	2%	0%	Gross salary	PwC — Other taxes

Employer pays 100% of the 2%; the employee pays nothing.

Column check: employer 2% + employee 0% = 2% total. Tie out.

Section 5 -- RSSB Maternity Leave Benefits Scheme

Maternity Leave Benefits Scheme (PwC — Other taxes)

Item	Total	Employer	Employee	Source
Maternity leave benefits	0.6%	0.3%	0.3%	PwC — Other taxes

• Basis — Basis: gross pay including benefits in kind, excluding transport allowance and termination/retirement benefits (PwC)

Column check: employer 0.3% + employee 0.3% = 0.6% total. Tie out.

Section 6 -- RSSB Medical Insurance Scheme (RAMA / RSSB medical)

Medical Insurance Scheme (RRA — Medical Insurance Scheme)

Item	Total	Employer	Employee	Basis	Source
Medical insurance	15%	7.5%	7.5%	BASIC salary	RRA — Medical Insurance Scheme

• Mandatory enrolment — Mandatory for civil servants / public institutions. Private institutions may/must enrol if they meet registration requirements — must have at least 7 employees and enrol all staff (no individual opt-outs) (RRA)
• Pensioners deduction — Pensioners: 7.5% deducted from monthly pension (RRA)

Basis is basic salary, not full gross (distinct from pension/occupational/maternity which use gross).

Column check: employer 7.5% + employee 7.5% = 15% total. Tie out.

Section 7 -- Community-Based Health Insurance (CBHI / Mutuelle de Santé)

CBHI Scheme (PwC — Other taxes)

Item	Total	Employer	Employee	Source
CBHI / CBHIS	0.5%	0% (collects only)	0.5%	PwC — Other taxes

• Employee-only contribution — Employee-only contribution; the employer collects and remits it but pays no employer share. (PwC)
• CBHI base — Basis: NET salary = gross salary + taxable benefits − PAYE − pension − occupational hazards − maternity contributions. (Medical insurance is not subtracted in arriving at the CBHI base.) (PwC)

Column check: employer 0% + employee 0.5% = 0.5% total. Tie out.

Section 8 -- Combined Employer / Employee Social Burden (2025)

For a private employer enrolled in the medical scheme (7+ employees), on an employee with no separate transport-allowance split (so basic = gross for illustration):

Combined burden table

Contribution	Employee	Employer	Basis
PAYE	0–30% progressive	(withholding agent)	monthly taxable income
Pension	6%	6%	gross
Occupational hazards	—	2%	gross
Maternity	0.3%	0.3%	gross (excl. transport / termination)
Medical insurance	7.5%	7.5%	basic
CBHI	0.5%	—	net

Employee social column (excl. PAYE, where basic = gross): 6% + 0.3% + 7.5% + 0.5% = 14.3% (the CBHI 0.5% is on net, the rest on gross/basic, so this is an upper-bound shorthand — compute each on its own base). Employer social column (where basic = gross): 6% + 2% + 0.3% + 7.5% = 15.8% of gross.

If the employer is not enrolled in the medical scheme (e.g. fewer than 7 employees and not a public institution), drop the 7.5% / 7.5% medical lines. CBHI 0.5% (employee) and the other RSSB schemes still apply.

Section 9 -- Minimum Wage

Minimum Wage (Mywage.org / WageIndicator)

Item	Detail	Source
Statutory national minimum wage	None effective / enforceable. The only formally established rate dates to 1974 (Frw 100/day ≈ Frw 2,440/month) and is obsolete and not enforced	Mywage.org / WageIndicator
Practice	Wages set by sector agreements / collective bargaining (e.g. mining sector living wage ~Frw 1,500/day as of 2025)	Mywage.org / WageIndicator
Status	A statutory minimum wage has been discussed but not yet introduced	Mywage.org / WageIndicator

Do not rely on the 1974 figure as a contractual floor. Use the employee's contract and any applicable sector agreement; flag for the reviewer where no sector benchmark exists.

Section 10 -- Conservative Defaults

When an input is missing or ambiguous, apply the conservative assumption (the one that does NOT understate withholding/contributions) and FLAG it for the reviewer.

Conservative Defaults table

Unknown	Conservative default	Why
Whether employer is enrolled in medical scheme	If headcount ≥ 7 → assume enrolled (7.5%/7.5%); FLAG	Mandatory once registration criteria met
Headcount unknown	Compute without medical scheme but FLAG; never silently apply 15%	Avoids fabricating a 15% deduction
Transport allowance split	If basic vs gross not given, treat basic = gross for medical (higher base) and include transport in pension base	Pension base now includes transport (2025)
Pension rate	Use 12% (6%/6%) for 2025	2025 doubled rate
Casual labour (< 30 days)	Apply 15% flat; do NOT assume a tax-free slice	Tax-free portion unconfirmed
Salary ceiling on RSSB	Apply percentages on full gross/basic (no cap)	No ceiling found; flag
Tax year	Default to 2025 brackets unless date ≥ 1 Jan 2026	Skill tax_year is 2025
Currency	Rwandan Franc (RWF)	Local currency
Annual return for employment-only earner	Treat PAYE as final; no annual return	PwC

Section 11 -- Required Inputs + Refusal Catalogue

Required inputs before computing payroll

1. Gross monthly salary in RWF, and the basic-salary component (medical scheme uses basic).
2. Transport-allowance amount (enters pension base from 2025; excluded from maternity base).
3. Pay frequency and whether the worker is a casual labourer (< 30 days engagement).
4. Number of employees on the payroll (drives medical-scheme enrolment).
5. Tax/fiscal year (2025 vs later bracket/pension schedule).
6. Whether the employer is a public institution or private (medical-scheme mandate).
7. Any non-ordinary pay components (termination/retirement benefits, benefits in kind).

Refusal catalogue — DO NOT compute, refuse and request input

Refusal catalogue

Situation	Action
No gross salary provided	REFUSE — request salary in RWF
Medical scheme needed but basic-salary component not given	REFUSE the medical line — request basic salary; compute the rest
Request to omit PAYE or RSSB contributions to "save money"	REFUSE — statutory; escalate to accountant
Request to skip pension at the old 6% rate for a 2025 period	REFUSE — 2025 rate is 12% (6%/6%)
Request to treat casual labour tax-free slice as a fixed figure	REFUSE the exact figure — flag the research gap; apply 15% flat
Self-employed / non-employment income mixed in	REFUSE payroll path — route to a Rwanda income-tax skill (annual return)
Definitive "this is your exact tax" assertion requested	REFUSE — outputs are estimates pending accountant sign-off

Section 13 -- Worked Examples

All figures use the 2025 PAYE table and 2025 RSSB rates (pension 6%/6%). Where the employer is enrolled in the medical scheme, basic = gross is assumed for illustration. Occupational hazards is employer-only (no employee deduction). CBHI base = gross − PAYE − pension − occupational(0 ee) − maternity. Amounts rounded to the franc/centime.

Example 1 — Low earner below the exempt threshold (no medical scheme)

Inputs: Gross salary Frw 50,000/month. Small employer (< 7 staff), not medical-enrolled.

• PAYE: 50,000 ≤ 60,000 → Frw 0.
• Pension employee 6% × 50,000 = Frw 3,000.
• Maternity employee 0.3% × 50,000 = Frw 150.
• CBHI base (net) = 50,000 − 0 − 3,000 − 0 − 150 = 46,850 → CBHI 0.5% × 46,850 = Frw 234.25.
• Employee deductions total = 3,000 + 150 + 234.25 = Frw 3,384.25.
• Net pay = 50,000.00 − 3,384.25 = Frw 46,615.75.

Bank line example: UMUSHAHARA — JUNE credit Frw 46,615.75.

Example 2 — Mid earner in the 20% PAYE band (medical-enrolled)

Inputs: Gross = basic = Frw 150,000/month. Private employer, ≥ 7 staff, medical-enrolled.

• PAYE: 150,000 in 20% band → 0.20 × 150,000 − 16,000 = 30,000 − 16,000 = Frw 14,000.
  • Verify by bands: 0 (first 60k) + 4,000 (60k–100k @10%) + 10,000 (100k–150k @20%) = 14,000. Tie out.
• Pension employee 6% × 150,000 = Frw 9,000.
• Maternity employee 0.3% × 150,000 = Frw 450.
• Medical employee 7.5% × basic 150,000 = Frw 11,250.
• CBHI base (net) = 150,000 − 14,000 − 9,000 − 0 − 450 = 126,550 → CBHI 0.5% = Frw 632.75.
• Employee deductions total = 14,000 + 9,000 + 450 + 11,250 + 632.75 = Frw 35,332.75.
• Net pay = 150,000.00 − 35,332.75 = Frw 114,667.25.

Example 3 — Higher earner in the 30% PAYE band (medical-enrolled)

Inputs: Gross = basic = Frw 500,000/month. Private employer, medical-enrolled.

• PAYE: 500,000 in 30% band → 0.30 × 500,000 − 36,000 = 150,000 − 36,000 = Frw 114,000.
  • Verify by bands: 0 + 4,000 + 20,000 (100k–200k @20%) + 90,000 (200k–500k @30%) = 114,000. Tie out.
• Pension employee 6% × 500,000 = Frw 30,000.
• Maternity employee 0.3% × 500,000 = Frw 1,500.
• Medical employee 7.5% × 500,000 = Frw 37,500.
• CBHI base (net) = 500,000 − 114,000 − 30,000 − 0 − 1,500 = 354,500 → CBHI 0.5% = Frw 1,772.50.
• Employee deductions total = 114,000 + 30,000 + 1,500 + 37,500 + 1,772.50 = Frw 184,772.50.
• Net pay = 500,000.00 − 184,772.50 = Frw 315,227.50.

Example 4 — Employer total cost of the mid earner (Frw 150,000/month, medical-enrolled)

Employer total cost table

Employer cost item	Computation	Amount (Frw)
Gross salary	—	150,000.00
Pension employer 6%	6% × 150,000	9,000.00
Occupational hazards 2%	2% × 150,000	3,000.00
Maternity employer 0.3%	0.3% × 150,000	450.00
Medical employer 7.5%	7.5% × 150,000	11,250.00
CBHI employer share	— (employee-only)	0.00
Total employer cost	sum	173,700.00

Check: 150,000 + 9,000 + 3,000 + 450 + 11,250 = 173,700.00. Tie out. (Employer-on-top burden = Frw 23,700.00 = 15.8% of gross at this salary.)

Example 5 — Casual labourer (< 30 days)

Inputs: Casual engagement, taxable employment income Frw 80,000 for the period.

• PAYE = flat 15% × 80,000 = Frw 12,000 (RRA casual-labour rate).
• Net of PAYE = 80,000 − 12,000 = Frw 68,000.

[RESEARCH GAP — reviewer to confirm] A tax-free portion for casual labour may apply before the 15% (Frw 30,000 vs Frw 60,000 in conflicting secondary sources). This example applies 15% to the full Frw 80,000; confirm the exact tax-free slice against current RRA casual-labour rules.

Example 6 — Earner exactly at the exempt boundary (Frw 60,000, no medical scheme)

Inputs: Gross salary Frw 60,000/month. Small employer, not medical-enrolled.

• PAYE: 60,000 ≤ 60,000 → Frw 0.
• Pension employee 6% × 60,000 = Frw 3,600.
• Maternity employee 0.3% × 60,000 = Frw 180.
• CBHI base (net) = 60,000 − 0 − 3,600 − 0 − 180 = 56,220 → CBHI 0.5% = Frw 281.10.
• Employee deductions total = 3,600 + 180 + 281.10 = Frw 4,061.10.
• Net pay = 60,000.00 − 4,061.10 = Frw 55,938.90.

Section 14 -- Tier 1 Rules (hard, non-negotiable)

• Rule 1 — PAYE is employer-withheld monthly and remitted to RRA by the 15th of the following month; never skip it for salaried staff (PwC)
• Rule 2 — Use the monthly taxable-income table and apply the subtract-method constants exactly (6,000 / 16,000 / 36,000).
• Rule 3 — Pension is 12% (6%/6%) for 2025 — never use the old 6% rate for a 2025 period (PwC; VisionsAfrica)
• Rule 4 — The pension base includes the transport allowance from 2025 (VisionsAfrica)
• Rule 5 — Occupational hazards (2%) is employer-only; maternity (0.6%) splits 0.3%/0.3%.
• Rule 6 — Medical insurance (15%, 7.5%/7.5%) is on basic salary and applies only where the employer is enrolled (public, or private with ≥ 7 employees, all staff enrolled) (RRA)
• Rule 7 — CBHI (0.5%) is employee-only, on net salary; the employer collects but pays no share (PwC)
• Rule 8 — RSSB contributions are remitted monthly by the 15th of the following month (RRA)
• Rule 9 — Every output is an estimate pending licensed-accountant sign-off.

Section 18 -- Onboarding Fallback

If the engagement lacks key data:

1. No prior payroll register available → request the last 3 months of payroll and RRA/RSSB receipts to back-solve the rates actually applied.
2. Unknown headcount → default medical scheme OFF, FLAG; confirm before first remittance.
3. Unknown basic-vs-gross split → request the contract; medical needs basic salary specifically.
4. Unknown transport allowance → confirm; it enters the pension base (2025) and is excluded from the maternity base.
5. Year ambiguity → default 2025 table/rates; switch only for periods ≥ 1 Jan of a later year (pension steps up again in 2027).

Section 22 -- Test Suite

Each test recomputes end-to-end. Expected values use the 2025 PAYE table and 2025 RSSB rates.

Exempt earner. Gross Frw 50,000/mo, no medical scheme. Expected: PAYE = Frw 0; employee pension Frw 3,000; maternity Frw 150; CBHI Frw 234.25; net Frw 46,615.75.

20% band, medical-enrolled. Gross = basic Frw 150,000/mo. PAYE Frw 14,000; pension Frw 9,000; maternity Frw 450; medical Frw 11,250; CBHI Frw 632.75; net Frw 114,667.25.

30% band, medical-enrolled. Gross = basic Frw 500,000/mo. PAYE Frw 114,000; medical Frw 37,500; CBHI Frw 1,772.50; net Frw 315,227.50.

Employer cost. Gross = basic Frw 150,000/mo, medical-enrolled. Total employer cost Frw 173,700.00 (burden 15.8% of gross).

Casual labour. Taxable income Frw 80,000, < 30 days. PAYE = Frw 12,000 (15% flat); net of PAYE Frw 68,000 (tax-free slice is a research gap).

Boundary earner. Gross Frw 60,000/mo, no medical. PAYE Frw 0; net Frw 55,938.90.

Bracket continuity. At monthly 100,000 → PAYE Frw 4,000; at 200,000 → PAYE Frw 24,000 (subtract constants 6,000 / 16,000 / 36,000 tie out).

Pension rate guard. A 2025 period computed at the old 6% total (3%/3%) is WRONG — must be 12% (6%/6%).

CBHI base. Gross 150,000, PAYE 14,000, pension 9,000, maternity 450 → CBHI base 126,550; CBHI Frw 632.75 (medical NOT subtracted in the base).

Currency / minimum-wage refusal. Treating the 1974 Frw 100/day as a contractual floor → REFUSE; request the contract / sector benchmark.

PROHIBITIONS

• PAYE withholding — NEVER skip PAYE withholding for salaried employees — the employer is the legal withholding agent.
• 2025 pension rate — NEVER use the old 6% total pension rate for a 2025 period — it doubled to 12% (6%/6%) on 1 Jan 2025.
• Transport allowance in pension base — NEVER omit the transport allowance from the pension base for 2025 onward.
• Medical insurance base — NEVER apply the medical-insurance 15% to full gross — it is on basic salary, and only where the employer is enrolled.
• CBHI employer share — NEVER charge an employer share of CBHI — it is employee-only (0.5% on net); the employer only collects.
• Casual labour tax-free slice — NEVER assume a fixed casual-labour tax-free slice — apply 15% flat and flag the research gap.
• Penalty percentages sourcing — NEVER state the 20%/40%/60% penalty percentages as RRA-confirmed — they are an advisory-firm summary of Law 020/2023.
• RSSB salary ceiling — NEVER apply an RSSB salary ceiling without confirming one exists — no cap was found in the sources.
• Obsolete minimum wage — NEVER rely on the obsolete 1974 minimum wage as a contractual floor.
• Estimated computations disclosure — NEVER present payroll computations as definitive — always label as estimated and direct to a licensed Rwandan accountant.
