Invoicing Software for Nunavut Accounting Firms

How does invoicing software work for firms in Nunavut?

The CRA administers the GST. Nunavut levies no territorial sales tax.

A Nunavut firm bills its own fees with 5% GST and nothing else — no provincial tax on the invoice and no second remittance account. The friction in billing here is never the tax; it is scope that was agreed verbally.

What is different about running a practice in Nunavut?

Four things a firm working Nunavut files should be able to state without looking them up. Each is verified against a primary source, linked at the foot of this page.

CPA Northwest Territories/Nunavut is the provincial body; 276 of Nunavut's 277 employer businesses were small businesses as of December 2024.

• The smallest business base in Canada — Nunavut had fewer than 300 employer businesses as of December 2024, almost all of them small. A firm serving Nunavut is serving a defined, countable market.
• The highest small-business rate in the country — Nunavut's territorial small-business rate is 3% on the first $500,000 of active business income — the highest provincial or territorial small-business rate in Canada.
• Northern residents deductions apply — All of Nunavut is a prescribed Zone A for the federal northern residents deductions, which materially affects nearly every personal return prepared in the territory.
• No territorial sales tax — Nunavut businesses charge 5% GST only. There is no territorial sales tax registration or return.

Managing invoicing software across a client book in Nunavut

A firm's billing problem starts before the invoice: unless scope and price were agreed in writing, every bill is a negotiation.

An Iqaluit-serving practice — whether based in the territory or in Ottawa — works with no road access between communities and intermittent connectivity. Cloud accounting is not a preference here; it is the only way records move. Deadlines are the same federal deadlines as everywhere else, which is precisely the problem: the calendar does not adjust for a sealift schedule, so the practice starts every file earlier than it would down south.

How SpidNums handles it

SpidNums models the firm as clients, services and work. Assigning a typed service to a Nunavut client is what generates the recurring projects, the stages and the reminders — the cadence is recorded once rather than remembered each period.

Every open obligation is then ranked by how close its due date sits and coloured accordingly, so the morning question — what is late, what is close, what is fine — is answered by looking.

• Services catalogue with per-service pricing lines
• Engagement letters built from assigned services or prior-year history
• Firm letterhead and branding on every client-facing document
• Client e-signature by type, draw or upload on a no-login page
• Signed PDF stored on the client record
• Annual renewal prompts when scope changes

Which CRA deadlines apply?

These rules are federal and apply in every province and territory. Where a due date falls on a weekend or public holiday, the CRA treats the next business day as on time — compute the shifted date each year rather than carrying the calendar forward.

What SpidNums does not do

SpidNums is practice management with an invoicing workflow, not an accounts-receivable ledger. It produces the priced, signed engagement that your billing runs from — it does not process payments or age receivables.

That distinction matters more in a small market. A Nunavut practice is usually serving clients across a wide area with a small team, and the last thing it needs is a system that duplicates the tools it already trusts.
