The verdict in three sentences
Formalizing early means invoicing legally and reassuring clients from your first serious contract. The real decision is staying informal vs registering a sole proprietorship, which unlocks a KRA PIN and a simplified tax path. An invoice with a valid tax number often makes the difference in landing a B2B or public contract.
Sole proprietor registration in Kenya in 2026
In Kenya, a sole proprietorship is registered on the eCitizen portal via the Business Registration Service, and the Kenya Revenue Authority issues the KRA PIN. Small businesses below the VAT threshold can use turnover tax, a simplified regime ideal for a web freelancer leaving the informal sector.
| Status | Indicative 2026 threshold | Taxation | Obligations |
|---|---|---|---|
| Informal | — | None (but illegal to invoice) | None, but blocks B2B |
| Sole proprietor (turnover tax) | Turnover below VAT threshold (~KES 5M) | Turnover tax on gross sales | Simplified filing |
| Sole proprietor (normal) | No cap | Personal income tax | Basic bookkeeping |
| Limited company | No cap | Company income tax | Statutory accounts |
Exact thresholds vary by activity and year; treat these as a 2026 order of magnitude.
Informal or registered: the real math
Staying informal looks free but costs lost contracts and audit risk. Registration has a low cost yet unlocks invoicing, a corporate account and trust.
| Criterion | Informal | Registered (sole proprietor) |
|---|---|---|
| Legal invoicing | Impossible | Yes |
| Access to B2B/public | Very limited | Open |
| Annual cost | 0 but lost opportunities | Low, simplified |
| Corporate account | Difficult | Possible |
| Tax risk | High | Controlled |
| Credibility | Low | Solid |
Mini case study
Wanjiru, a freelance web writer in Nairobi, invoices KES 900,000 per year off the books. An agency offers a recurring contract worth KES 450,000 but requires an invoice with a KRA PIN. She registers as a sole proprietor: near-free registration, modest turnover tax. The contract far outweighs the cost, and she secures two more clients who refused informal payments.

FAQ
Is turnover tax suitable for a web freelancer?
Yes, it is designed for small businesses. As long as your turnover stays below the VAT threshold (around KES 5M as a 2026 order of magnitude), you benefit from a simplified tax on gross sales.
Can I invoice legally right after registering?
Yes. Once registered you obtain a KRA PIN, which makes your invoices valid and deductible for your clients.
How much does the status cost per year?
Registration is low or near-free, and turnover tax stays modest under the threshold. Against the contracts you win, the return is immediate.
What happens if I exceed the threshold?
You move to VAT registration and normal income tax with full bookkeeping. That is a good sign: your business is growing.
Do I need to contribute to social funds?
Depending on your setup, contributions such as NHIF/NSSF successors may apply. Check with the local funds; they open health and pension rights.
