It is one of the first questions every Kenyan founder faces and one of the most confidently answered by people who have never done the maths. The truthful answer: at typical SME profit levels a sole proprietorship usually pays less tax — and the good reasons to form a limited company are mostly not about tax at all.
How each structure is taxed
A sole proprietor and the business are the same person. Profits are taxed once, on the owner's individual return, at graduated rates with a personal relief of KES 28,800 a year:
| Annual taxable income | Rate |
|---|---|
| Up to KES 288,000 | 10% |
| KES 288,001 – 388,000 | 25% |
| KES 388,001 – 6,000,000 | 30% |
| KES 6,000,001 – 9,600,000 | 32.5% |
| Above KES 9,600,000 | 35% |
A limited company is a separate taxpayer. It pays corporation tax at a flat 30% of profit — and when it pays those profits to you as dividends, a further 5% withholding tax applies. Money you take as salary is deductible for the company but taxed through PAYE at the same graduated rates above.
The maths at real profit levels
Assume the owner takes all the profit out each year:
| Annual profit | Sole proprietor | Company (30% + 5% on dividends) |
|---|---|---|
| KES 500,000 | ≈ KES 58,600 (12%) | ≈ KES 167,500 (34%) |
| KES 1,500,000 | ≈ KES 358,600 (24%) | ≈ KES 502,500 (34%) |
| KES 3,000,000 | ≈ KES 808,600 (27%) | ≈ KES 1,005,000 (34%) |
| KES 8,000,000 | ≈ KES 2,358,600 (29%) | ≈ KES 2,680,000 (34%) |
The pattern is clear: distributing everything through a company costs around 33–34% at every level, while the sole proprietor climbs gradually and only approaches 30% at large profits. A company narrows the gap when profits are retained and reinvested (30% flat, no dividend tax yet) or when salary and dividends are blended deliberately — but a company is rarely formed to save tax, and it rarely does at these profit levels. Businesses under KES 25 million turnover also have the turnover tax option under either structure.
What the company actually buys you
- Limited liability: business debts and lawsuits stop at the company — your home and savings are not on the table.
- Credibility and contracts: many corporates, NGOs and tenders will only contract a registered company; some payment terms and credit lines follow the same rule.
- Bringing in others: partners, investors and employee shares all need a share structure only a company has.
- Continuity: the company outlives its owner and can be sold or passed on cleanly.
What the company costs you
- More compliance: a corporation tax return (due six months after year end), annual returns to the Registrar and PAYE the moment you pay yourself a salary.
- Audit expectations: the Companies Act exempts small private companies (turnover up to KES 50 million, assets up to KES 20 million, under 50 employees) from statutory audit — but banks, tenders and investors frequently ask for audited accounts anyway.
- Discipline about whose money it is: the company's cash is not your cash. Directors' withdrawals that aren't salary or dividend create a directors' loan account that must be squared — the discipline in our business money guide applies double.
Incorporate when the business needs limited liability, corporate clients, tenders or investors — not to save tax. If the spreadsheet is the only argument for the company, the sole proprietorship usually wins it.
Deciding for your business
- Work out last year's profit and read it against the tables above.
- List who you sell to — if corporates or tenders are the growth plan, the company case strengthens regardless of tax.
- Weigh your risk: premises, staff, debt and inventory all argue for limited liability.
- If you incorporate, plan the salary and dividend mix before the first withdrawal, not after.
