A sole proprietorship in Kenya is a business owned by one individual and trading under a name registered with the Business Registration Service (BRS). It is quick to set up, but the owner is personally liable for business debts, and VAT registration still applies once taxable turnover passes the threshold.
Under the Business Registration Service Act 2015, an individual who trades under a name other than their own registers that business name with BRS. Registration gives you a certificate in the business name and a public record that customers and banks can check. There is no separate legal person: the business and the owner are one and the same in law.
You search and reserve the name on the eCitizen portal, then submit the owner's identification, KRA PIN, contact details and the nature of the business. Names that are identical or deceptively similar to existing ones are refused, and some words are restricted. A distinctive name that also suits a future domain name saves you a rebrand later.
Registered names must be renewed and kept up to date with BRS; changes of address or owner details should be notified rather than left to lapse. An expired or stale registration can create trouble when a bank, a landlord or a county licensing office asks for current documents.
Partners who trade together under one name register it as a partnership business name, and each partner is liable for the debts jointly. Ask an advocate to draft a written partnership deed covering profit sharing, withdrawals and what happens if one partner leaves, because the default position under the law rarely matches what friends assumed.
The defining feature is unlimited personal liability. If the business cannot pay a supplier or a court judgment, creditors can pursue the owner's personal assets. For a freelancer with few commitments that may be acceptable; for a trader who signs leases, buys stock on credit or employs staff, it is a serious exposure worth weighing against the cost of a company.
For tax, the owner uses their personal KRA PIN and reports business income on their individual return through iTax. The deadline for individual annual returns is 30 June of the following year. If you employ people, you also register as an employer for PAYE, and you must keep records that support every figure in the return.
Whether you pay income tax on profit or a turnover-based tax depends on your turnover band and the rules in force that year. Those rates and bands are amended by finance legislation, so check the current KRA guidance or ask an accountant instead of copying a rate from an older article.
County governments issue trading licences and charge their own fees for operating premises, signage or food handling. These are separate from BRS registration and KRA, and a business that has only a business name certificate can still be closed by a county inspector for lacking a single business permit.
Registering a business name does not by itself make you a VAT agent. Registration becomes compulsory when taxable supplies exceed KES 5 million over a twelve-month period, and you may also register voluntarily if your customers are VAT-registered businesses that want to reclaim input VAT on your invoices.
Once registered, you must charge VAT on taxable supplies, issue proper tax invoices and file returns. KRA requires VAT-registered taxpayers to use eTIMS for their invoices, so the enrolment should be done before your first VAT invoice rather than after a customer rejects one.
Even below the threshold, issue numbered invoices or receipts and keep copies. Corporate buyers increasingly insist on invoices that satisfy their own tax-deduction rules, and a trader who can produce clean documents wins that work more easily than one who writes figures on a notebook page.
The common trigger is growth in risk rather than turnover. Signing a lease, taking supplier credit, employing a team or bidding for tenders that expect a company all push towards incorporation. Investors also cannot take shares in a business name, so any plan to raise funds requires a company first.
Moving is not a rename. The company is a new legal person, so contracts, licences, bank accounts, KRA registrations and the like must be transferred or reissued, and stock or equipment moved in a documented way. Plan the date, notify customers of the new legal entity and update your invoice details at the same moment.
A middle path some founders consider is a limited liability partnership if they work with a co-owner in a professional setting. The structure has its own rules under the Limited Liability Partnerships Act, so speak to an advocate before assuming it fits your business.
Run the numbers before switching. Compare the extra cost of annual company filings and accounting with the value of liability protection, and ask your accountant to model how profit extraction through salary and dividends would be taxed compared with your current personal tax. The answer differs by income level, so do not rely on a rule of thumb.
4invoices.net lets you produce PDF invoices and keeps an archive, which is enough to show a customer or an accountant what you billed. It does not transmit invoices to KRA, so if you are VAT-registered you complete eTIMS enrolment separately with KRA and an approved solution.
Send payment reminders and delivery notices by SMS or e-mail from 4notify.net when you decide to; nothing is scheduled automatically. A short message from your own account the day an invoice falls due often recovers late payments faster than a formal letter.
Keep business money apart from personal money even though the law treats you as one person. A separate account and a simple monthly record of takings and expenses will make the iTax return, a loan application and any KRA query far easier to answer.
It is tempting to assume that a small sole trader has no real invoicing obligations, yet eTIMS applies once VAT-registered.
Check with KRA whether eTIMS applies once you are VAT-registered. 4invoices.net produces PDF invoices only; it does not transmit invoices to KRA.
Tracking the KES 5 million VAT registration threshold manually is error-prone.
Track your turnover against the KES 5 million VAT threshold yourself, using your invoice archive as the record. 4b2b does not monitor the threshold or send threshold alerts.
Late-paying customers are chased only when cash runs short.
Send a reminder yourself by SMS or e-mail from 4notify.net when an invoice falls due. Reminders are not scheduled automatically.
No. A registered business name belongs to an individual or partners who remain personally liable, while a limited company is a separate legal person. The name is registered with BRS, but the owner still files income tax on their personal PIN and carries unpaid business debts personally. Creditors can therefore pursue the owner's personal assets if the business fails to pay.
Many banks accept a registered business name, usually asking for the certificate, the owner's identification, KRA PIN and proof of address. Requirements differ by bank and account type, so ask your bank for its checklist before visiting, and expect extra checks on the source of funds. Opening a separate account also keeps your personal spending out of the business records.
A sole proprietor generally files with their personal PIN, since the business is not a separate taxpayer. Obligations such as VAT or PAYE are added to that PIN as registrations on iTax. Confirm the exact setup with KRA, because the profile you choose determines which returns appear. Ask KRA to confirm if you are unsure how your own profile is set up.
Registration is required when taxable supplies exceed KES 5 million within twelve months, and voluntary registration is possible below that. Once registered you charge 16 % where it applies, issue tax invoices and file returns. Take the date you cross the threshold from your invoice records and confirm it with KRA.
Changes and de-registration are done with BRS through eCitizen, and the process asks for the certificate and identification. Close your KRA obligations in parallel, filing outstanding returns and cancelling tax registrations on iTax, so that no penalties accrue on a business that has stopped trading. Retain the closure confirmation, because banks and landlords may ask for it later.
