How to Register a Sole Proprietorship in Nunavut

Registering a sole proprietorship in Nunavut is often optional: Nunavut business registration is only required when you carry on business under a name that is not your own exact legal name. A sole proprietor trading as "Jean Doe" can operate without filing anything, while "Jean Doe & Company" or an invented trade name must be declared to the Nunavut Legal Registries – Corporate Registries under the Partnership Act. This guide covers the rules, the fee, and how to file.

Do you need to register a Nunavut sole proprietorship?

The test is the name, not the activity. If you use your own legal name — first name and surname with nothing added — Nunavut does not require a business name registration. The moment you add wording such as "& Company", "Consulting", "Northern", or another person's name, you are using a business name and must file a Declaration of Use of a Business Name.

That declaration is made under Nunavut's Partnership Act and is administered by the Nunavut corporate registry — formally the Corporate Registries division of Legal Registries, Department of Justice, Government of Nunavut. Sole proprietors and partnerships use the same form. If you are still choosing a structure, compare a sole proprietorship and a corporation first.

What it costs to register in Nunavut

Fees come from the Partnership Act fee schedule published by Legal Registries. The amounts below are as published when this page was reviewed — confirm current figures with the registry before you file.

Nunavut's costs are modest compared with provinces that charge annual renewal fees; see how jurisdictions compare in business registration cost by province.

How to file your Nunavut business name declaration

There is no online filing portal. Legal Registries accepts submissions by email, mail, or in person, and does not accept faxes.

1. Confirm your name differs from your own legal name — adding "& Company" or similar wording triggers registration.
2. Complete the Declaration of Use of a Business Name form and have the business name user sign it.
3. Call Legal Registries to place a credit card on file, then scan the signed form as a 300-dpi PDF and email it to the registry. Never email credit card details.
4. Pay the $50 declaration fee; before filing, Legal Registries checks the proposed name for confusing similarity with existing names.
5. Keep your filed copy and receipt — banks and suppliers sometimes ask for proof of registration.

You may also mail or hand-deliver the form to the Iqaluit office. Note that the office was temporarily relocated to Suite 1517 for renovations, so confirm the current counter address before travelling.

Nunavut business name searches and naming rules

Nunavut does not require you to purchase a name search report for a business name declaration in the way a corporation does. The fee schedule lists searches as NIL, and Legal Registries reviews your proposed name for confusing similarity at no charge as part of the filing.

It is still sensible to confirm the name is not already in use. Learn how searches work in how to search for a business name in Canada and how to register a business name in Canada.

• Avoid names confusingly similar to an existing Nunavut or Canadian business.
• Avoid wording that suggests a government connection or requires special approval.
• Do not use "Limited", "Incorporated", or "Corp." in a sole proprietorship name — those are typically reserved for corporations.

Changing or ending your registration

If your business name, address, or the people involved change, file a declaration of change with Legal Registries; the fee schedule lists it at $25. When you stop using the business name, file a declaration of ceasing use, which carries no fee.

Unlike several provinces, Nunavut's published fee schedule sets out no renewal fee or fixed renewal term for business name declarations. That does not remove your obligation to keep the declaration accurate — confirm update and renewal expectations directly with Legal Registries.

Tax and licensing steps that follow registration

Registering a business name does not create a separate taxpayer. You remain a sole proprietor and report business income on your personal return using Form T2125. You will typically also need a Business Number (BN) from the CRA and — once you exceed the small-supplier threshold — a GST account. Nunavut is a GST territory rather than an HST province; confirm the current rate and threshold on the CRA website.

• CPP contributions on net self-employment income, with EI generally unavailable to self-employed people unless they opt in.
• T4A slips when you pay fees to contractors or other workers.
• Municipal business licences, which may apply in Iqaluit or other communities — check with the city or hamlet.
• CRA My Business Account for filings, balances, and correspondence.
