Incomplete documentation is the single biggest cause of delayed company registrations in Kenya. BRS data shows that a large proportion of queried applications trace back to missing KRA PINs, mismatched ID details, or incorrectly structured share capital. This checklist covers every document you need to register a company in Kenya, why each one matters, and the exact mistakes that get applications rejected.
Many entrepreneurs start the company registration process in Kenya with strong momentum, only to be delayed within days. This is rarely due to the idea itself, but rather missing documents, mismatched details between IDs and KRA PINs, or errors in share structure submissions.
Company registration in Kenya is clearly defined under the Companies Act, 2015, and the eCitizen system is fully functional. However, success depends on preparation. A complete and accurate application can be processed in 3 to 5 business days, while incomplete submissions often trigger BRS queries that extend the timeline by several days.
Below is a complete breakdown of the documents required for registering a company in Kenya in 2026, along with the purpose of each requirement and the most common mistakes applicants make.

Why Getting Your Documents Right Matters More Than You Think
The Business Registration Service (BRS) treats company registration records as legal documents. Every director and shareholder entered into the Companies Registry must be accurately identified and linked to valid government records.
This is why even seemingly minor errors can delay an application. A name mismatch between an ID document and a KRA PIN certificate isn’t treated as a simple typo. BRS must verify the identity of every person being registered before approving the application.
Some of the most common causes of registration delays include:
- Names on ID documents that don’t exactly match KRA PIN records
- Missing KRA PIN certificates for directors or shareholders
- Incorrect or incomplete shareholder information
- Errors in share allocation and ownership details
- Missing supporting documents required during submission
Many applicants assume they can correct these issues later in the process. In reality, BRS will usually raise a query and pause the application until the issue is resolved.
For this reason, document preparation should be treated as more than a simple checklist. Each document serves as a verification point that BRS cross-checks against government records, making accuracy essential at every stage of the registration process.
Company Registration Requirements in Kenya
The documents required for registering a company in Kenya fall into four categories: identity documents for individuals, tax compliance documents, company-level information, and supporting professional requirements.
Category 1: Identity Documents for Directors and Shareholders
These are used by BRS to verify the legal identity of the individuals who will be registered as controllers of the company.
| Document | Important Notes |
| National ID card (Kenyan citizens) | Clear color scan of both sides. The name must match exactly across all other documents. |
| Valid passport (alternative to ID or for non-citizens) | Color scan of photo page. Must be valid, not expired. |
| Passport-size photograph | Recent, clear, against a plain background for each director and shareholder. |
| Proof of residential address | Utility bill or bank statement no older than three months. Required for foreign nationals. |
The most critical rule across all identity documents is consistency. The name on the ID or passport must be identical to the name under which the KRA PIN is registered.
If your national ID reads John Kamau Njoroge but your KRA PIN was registered as John Njoroge, that discrepancy will trigger a BRS query. Resolve any name inconsistencies at the KRA iTax portal before you begin the registration process.
Category 2: Tax Compliance Documents
Kenya Revenue Authority (KRA) PIN certificates are mandatory for every individual and entity involved in the company registration. This requirement comes directly from the Companies Act and can’t be bypassed or deferred to after registration.
| Document | Important Notes |
| KRA PIN certificate for each director | PIN must be active and registered under the exact same name as the director’s ID. |
| KRA PIN certificate for each shareholder | A shareholder who is also a director still needs only one PIN, but it must be confirmed active. |
| KRA PIN for non-citizen directors or shareholders | Obtainable through KRA iTax portal using a foreign passport. Must be in place before submission. |
KRA PINs for individuals are registered through the iTax portal at itax. Foreign nationals can obtain a KRA PIN online using their passport without being physically present in Kenya.
Category 3: Company-Level Information and Decisions
Beyond individual documents, there are several company-level decisions that must be made and documented before the BRS application can be completed.
| Information Required | Important Notes |
| Proposed company name (with two or three alternatives) | Must be unique, not deceptively similar to existing names, and compliant with BRS naming rules. |
| Physical registered office address in Kenya | Must be a street address. P.O. Boxes aren’t accepted under the Companies Act. |
| Description of business activities (company objectives) | Must clearly describe what the company will do. Vague descriptions are queried. |
| Share capital structure | Number of authorized shares, value per share, and how shares are allocated among shareholders. |
| Memorandum and Articles of Association | Generated from standard BRS templates through eCitizen, but share capital details must feed in correctly. |
The share capital structure is one area where many first-time applicants make costly mistakes. During registration, you must state your authorised share capital, and this figure directly affects the amount of stamp duty payable.
Stamp duty on share capital is charged at KES 20 for every KES 1,000 of authorized share capital, subject to the applicable minimum charge. Selecting an amount without understanding the implications can result in unexpected registration costs.
At Ultimus Advisory, we review share capital structures before submission to ensure the figures are accurate, appropriate for the business, and aligned with the registration requirements.
Category 4: Professional Requirements
The Companies Act, 2015 imposes two professional requirements on Private Limited Companies that must be addressed before the registration application is submitted, not after.
| Requirement | Important Notes |
| Qualified company secretary | Must be a Certified Public Secretary registered with the Institute of Certified Secretaries of Kenya. Their details are entered into the BRS application. |
| Company secretary ID and contact details | Full name, ID number, ICSK membership number, and address are required on the application form. |
A company secretary isn’t an optional compliance add-on. Under Section 241 of the Companies Act, every private company must have a qualified secretary.
Applications submitted without a company secretary on record are incomplete and won’t progress past the BRS review stage. If you don’t already have one, Ultimus Advisory can connect you with a qualified company secretary as part of the registration process.
Additional Requirements for Foreign Directors and Shareholders
Foreign nationals and Kenyans living abroad can register a company in Kenya using the same core documentation required for local registrations. However, additional documents are needed because the BRS must verify identities using records issued outside Kenya.
These additional requirements typically include:
- A valid foreign passport, including a clear color scan of the photo page and the page showing validity dates
- Proof of residential address in the country of residence issued within the last three months
- A KRA PIN obtained through the iTax portal using the foreign passport as the identification document
- For branch office registrations, certified copies of the parent company’s Certificate of Incorporation, Memorandum and Articles of Association, and details of the appointed local representative in Kenya
At Ultimus Advisory, we assist foreign investors and diaspora clients with the entire registration process, ensuring all documentation is correctly prepared and submitted without the need for physical presence in Kenya.
The Most Common Document Errors That Delay Registration
Based on the pattern of BRS queries we encounter the most at Ultimus Advisory, these are the errors worth specifically guarding against before you submit anything.
| Error | What It Causes |
| Name mismatch between ID and KRA PIN | BRS query, 3 to 7 day delay per correction round |
| Expired ID or passport submitted | Application rejected at document review stage |
| KRA PIN missing for one shareholder | Application stalls until PIN is obtained and resubmitted |
| P.O. Box listed as registered office address | BRS rejects the address and requests a physical street address |
| Share capital figures don’t add up | Payment invoice discrepancy, application held pending correction |
| Company secretary not in place at submission | Application marked incomplete, not progressed |
| Low-resolution or partial document scans | BRS can’t verify the document, triggers a query |
| Proposed name too similar to existing company | Name search fails, 24 to 48 hours lost, new name must be proposed |
How Long Does It Take to Register a Company in Kenya?
The timeline from start to Certificate of Incorporation depends almost entirely on how complete and accurate your documents are when the application is submitted.
| Scenario | Timeline |
| All documents complete, no BRS queries | 3 to 5 business days |
| One BRS query raised and resolved quickly | 7 to 10 business days |
| Multiple queries or missing KRA PINs | 2 to 3 weeks or longer |
| With Ultimus Advisory (pre-submission review) | 3 to 5 business days consistently |
The 3 to 5 business day timeline is achievable consistently when documents are correct before submission. Pre-submission review by an experienced registration team is what makes that timeline reliable rather than aspirational.
