Taxes and Customs Procedures
Lesson 1 of 5
30 min
Mukamana runs a furniture workshop in Musanze as a private limited company. It has six employees, sells about Frw 240 million of beds, desks and doors a year, and imports varnish and hinges from Kenya. Her accountant's wall calendar is full of tax dates: VAT and PAYE every month, an income tax prepayment every quarter, the trading licence tax by 31 January, the annual income tax return by 31 March, and duty and withholding tax each time a lorry of imports reaches customs. (An illustrative business.)
In S2 you met VAT and PAYE as a citizen and a future employee. At A-level you look at taxes as an entrepreneur does: as costs to plan for, obligations to meet on time, and rules that shape decisions such as whether to register a company, import or buy locally, and pay salaries or dividends.
Definition
Tax: a compulsory payment by a person or business to the government, without a direct service given in return, used to finance public spending. Taxpayer: the person or business required by law to pay or declare the tax.
Example: the corporate income tax Mukamana's company pays on its profit. A fee for a passport is not a tax, because it buys a specific service.
Definition
Tax base: the amount on which a tax is calculated (profit, salary, sales value, property value). Tax rate: the percentage or fixed amount applied to the base. Tax liability: the amount the taxpayer owes, base × rate.
Example: a taxable profit of Frw 36,000,000 (base) at 28% (rate) gives a liability of Frw 10,080,000.
Definition
Direct tax: a tax on income or wealth, borne by the person who pays it to RRA. Indirect tax: a tax on spending, paid to RRA by a seller or importer but passed on to the buyer in the price. Tax incidence: who finally bears the burden of a tax, which may differ from who hands the money to RRA.
Example: a shop pays VAT to RRA, but its customers bear most of it in the prices they pay.
Definition
Taxpayer Identification Number (TIN): the number that identifies a taxpayer on every declaration and payment, assigned when a business is registered. Tax declaration (tax return): the form, filed online with RRA, in which a taxpayer states the base and the tax due for a period.
Example: Mukamana's company quotes its TIN on its monthly VAT declaration.
The Rwanda Revenue Authority (RRA) assesses and collects central government taxes. It also collects three taxes on behalf of the districts, which keep the money for local services. The main laws, as listed by RRA in 2026, are Law N° 027 of 2022 establishing taxes on income (amended in 2023 and 2025), Law N° 049 of 2023 establishing value added tax (amended by Law N° 009 of 2025), Law N° 011 of 2025 establishing the excise duty, Law N° 020 of 2023 on tax procedures, and Law N° 048 of 2023 on the revenue of decentralised entities. Customs duty follows the East African Community's customs law and Common External Tariff.
| Tax | Base | Rate (RRA guide, 2023) | When declared and paid |
|---|---|---|---|
| Corporate income tax (companies) | Taxable profit | 28% | Annual return by 31 March; quarterly prepayments by 30 June, 30 September and 31 December |
| Personal income tax (sole traders, partners) | Annual business profit | 0%, 10%, 20%, 30% bands (lesson 3) | As above |
| Flat tax for micro-enterprises | Annual turnover up to Frw 12,000,000 | Nil up to Frw 2,000,000, then a fixed Frw 60,000, 120,000, 210,000 or 300,000 a year | As above |
| Lump-sum tax for small businesses | Annual turnover Frw 12,000,001 to 20,000,000 | 3% of turnover | As above |
| PAYE | Employees' monthly pay | 0%, 10%, 20%, 30% bands | Monthly, within 15 days after the month |
| Withholding taxes | Dividends, interest, royalties and some service fees; imports; public tenders | 15%; 5% of CIF value on commercial imports; 3% of a public tender invoice | Within 15 days after the month withheld |
| Value added tax | Value of taxable sales and imports | 18%, or 0% for zero-rated supplies such as exports | Monthly, or quarterly if turnover is Frw 200,000,000 or less |
| Trading licence tax (district) | Last year's turnover | Fixed amounts, e.g. Frw 160,000 a year for turnover of Frw 12 to 20 million | By 31 January |
Two exemptions matter to a new entrepreneur: a business with turnover of up to Frw 2,000,000 a year pays no income tax, and micro and small businesses pay no trading licence tax during their first two years (RRA, 2023).
Tip
Four questions for any tax. Who pays it to RRA? On what base? At what rate? By what date? If you can answer these four, you can plan for the tax in a budget and a cash flow forecast.
Worked example 1: which income tax regime?
Three sole traders in Huye have these annual turnovers: (a) a hair salon, Frw 1,800,000; (b) a tailor, Frw 6,500,000; (c) a stationery shop, Frw 15,000,000. Find each one's income tax under the regime that applies by default.
(a) Turnover is not more than Frw 2,000,000, so no income tax is due.
(b) Turnover lies in the Frw 4,000,000 to 7,000,000 band of the flat-tax table, so the tax is a fixed Frw 120,000 for the year.
(c) Turnover lies between Frw 12,000,001 and 20,000,000, so the lump-sum regime applies:
Comment: the shop may instead ask to be taxed on its actual profit if it keeps full accounts. That pays off when profit is small. If the shop made a profit of only Frw 750,000, personal income tax on it (lesson 3) would be francs, far less than Frw 450,000.
Worked example 2: a quarterly prepayment
Last year Mukamana's company paid corporate income tax of Frw 10,080,000 on a turnover of Frw 240,000,000. This year its turnover from April to June is Frw 66,000,000, and Frw 420,000 of tax was withheld from it at customs in that quarter. Find the prepayment due by 30 June.
Step 1: last year's tax as a share of turnover.
Step 2: apply it to this quarter's turnover. francs.
Step 3: deduct the tax already withheld. francs.
Answer: Frw 2,352,000 by 30 June. The final bill is settled in the annual return by 31 March, after deducting every prepayment, so a business that grows fast should save extra cash for it.
Warning
Do not confuse the regimes. Registering for VAT (turnover above Frw 20,000,000 in the last year, or Frw 5,000,000 in the last quarter) is a separate question from which income tax regime applies. And a tax withheld at customs or on a tender is not an extra cost: it is a prepayment of income tax, deducted when the business declares.
| Role | What it means | An example in Rwanda |
|---|---|---|
| Raise revenue | Pay for public goods that markets supply badly | Roads, schools, health centres, security |
| Redistribute income | Take a larger share from higher incomes | PAYE rises from 0% to 30% as pay rises |
| Discourage harmful goods | Raise the price of goods with social costs | Excise duty on alcohol and tobacco |
| Protect local industry | Make competing imports dearer | The EAC's 35% tariff band on goods the region makes |
| Encourage chosen activities | Lower taxes for activities the state wants more of | A newly listed company's lower income tax rate (Unit 6); zero-rated exports |
| Build self-reliance | Fund the budget at home rather than from loans and aid | Each franc raised at home is a franc the state need not borrow |
Taxes also have costs. High rates can push activity into the informal sector, and complicated rules cost small businesses time. Economists judge a tax by the old canons of taxation: it should be equitable (fair to ability to pay), certain (clear amounts and dates), convenient (easy to pay) and economical (cheap to collect), and modern writers add efficient (small distortions of choices) and flexible.
Important
A business that does not register, declare or pay on time faces interest and fines; hiding income or sales is tax evasion, a crime. Planning legally to pay less, for example by choosing a regime or claiming every allowed deduction, is tax avoidance and is lawful.
