Registering a Business in Kenya via BRS/eCitizen: A 2026 Guide

The verdict in three sentences

In Nairobi, the Business Registration Service (BRS) on the eCitizen portal registers a sole proprietorship (business name) in 1-3 days for about KES 950-1,000, KRA PIN included in the same flow. A private limited company costs roughly KES 10,650 in official fees over 3-7 days but shields your personal assets. Your KRA PIN and registration certificate are the two keys: without them, no compliant invoice, no corporate account, no serious contract.

Steps and costs on eCitizen

The BRS on eCitizen handles name search, registration, the certificate and links to the KRA for your PIN. Here are 2026 order-of-magnitude figures by structure.

For a fully digital venture (agency, online store, tech freelancing), a sole proprietorship is fine to start; upgrade to a limited company once you seek investment or bid for corporate tenders.

Sole proprietorship vs limited company

KRA PIN and first tax steps in Nairobi

Your KRA PIN is issued through the same eCitizen flow and appears on every invoice. Small businesses often fall under Turnover Tax (TOT) at around 3% of gross sales below the VAT threshold, while larger ones register for VAT at 16% and file monthly on iTax. Budget also for the annual single business permit from the county (Nairobi rates vary by size), and, once you hire, NSSF and SHIF/NHIF remittances.

Mini case study

Wanjiru, a designer in Nairobi, opens a branding studio. She registers a sole proprietorship: name search (KES 150) + registration (KES 950) = KES 1,100, with her KRA PIN issued within 2 days. In year one, on turnover of KES 3,000,000, Turnover Tax at 3% works out to about KES 90,000 for the year, paid monthly. She can now invoice with her PIN, open a business account and sign with real SMEs. Total to exist legally: about KES 1,100 and two days.
