How to Register a New Corporation With the Tax Authority

Tap through each step to see how a new corporation registers with the tax authority.

  1. Understand how incorporation and tax registration connect

    Finishing your company's legal incorporation doesn't automatically register it for tax purposes. In most countries, you must separately file a business/tax registration application with your national or local tax authority within a set window after incorporation, and the two filings are often combined into a single form.

  2. Gather the required documents

    A certificate of incorporation, articles of association, a shareholder register, and a lease agreement (if you have a physical premises) are typically required β€” corporations generally need more paperwork than sole proprietors.

  3. Apply through your tax authority's online portal

    Most tax authorities let you log in under the company's credentials, navigate to the business registration menu, attach your documents, and submit the application electronically.

  4. Know how this differs from sole proprietor registration

    A sole proprietor registers under the owner's own name, while a corporation registers as a separate legal entity with its own rights and obligations β€” which generally means more documentation and closer review.

  5. Receive your registration certificate

    Once the review is complete, a corporate tax registration certificate is issued, which you can usually view and print through the online portal.

  6. Learn your ongoing filing duties

    Once registered, recurring obligations such as sales tax/VAT and corporate income tax filings begin, so it helps to learn the filing calendar early.

Incorporating your company is only half the process

Completing your incorporation paperwork doesn't mean you can start operating yet β€” you still need to file a separate business/tax registration with the tax authority, and corporations generally face more document requirements than individual proprietors. This is general information and not a substitute for advice from a qualified accountant or tax professional, so confirm the exact documents and deadlines with your local tax authority.

Corporate registration differs from sole proprietor registration in a few key ways

Because a corporation is legally separate from the people who own or run it, tax authorities typically ask for more verification than they would for an individual business owner β€” proof of the entity's formation, its ownership structure, and sometimes its physical address. Knowing this going in helps you gather the right paperwork the first time instead of making multiple trips or resubmissions.

Frequently Asked Questions

Are incorporation and tax registration handled as a single application?

In many countries, yes β€” a single combined form covers both, but the exact process varies by jurisdiction, so it is worth confirming with your local tax authority beforehand.

Can I register for tax before incorporation is complete?

Generally, no. A company must complete its legal incorporation first, since it needs to exist as a distinct legal entity before it can register with the tax authority.
