Bookkeeping Software for New Brunswick Accounting Firms
Bank-rec review, month-end close and sales-tax return prep on one board.

Bookkeeping software for New Brunswick accounting firms means tracking the work rather than keeping the books: New Brunswick clients file one 15% HST return, and every corporate file runs a T2 six months after its fiscal year-end with the balance due earlier. SpidNums puts those obligations on one colour-coded board, hosted in Canada.

How does bookkeeping software work for firms in New Brunswick?
The CRA administers New Brunswick's HST.
For a bookkeeping practice that collapses two jobs into one. The reconciliation that closes the month also produces the 15% HST return, there is a single registration per client, and the input tax credits come off the same accounts the close already touched.
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.
| Filing | Applies to | Filing deadline | Payment | If it is late |
|---|---|---|---|---|
| GST/HST returns — monthly and quarterly filers | Registrants with monthly or quarterly reporting periods. | File and pay one month after the end of each reporting period. | Payment is due on the same date as the return. | The late-filing penalty is A + (B × C), where A is 1% of the amount owing, B is 25% of A, and C is the number of complete months the return is late, to a maximum of 12 — so 1% plus 0.25% per month, capped at 4%. A further $250 applies where the return is filed after a demand to file. Compound daily interest runs on late amounts. |
| GST/HST returns — annual filers | Registrants with an annual reporting period. | File and pay three months after the fiscal year-end. Annual filers who are individuals with business income and a December 31 year-end instead file by June 15 and pay by April 30. | Annual filers with $3,000 or more of net tax generally must also pay quarterly GST/HST instalments. | The same A + (B × C) late-filing formula applies. |
What is different about running a practice in New Brunswick?
Four things a firm working New Brunswick 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 New Brunswick is the provincial body; 20,256 of New Brunswick's 20,631 employer businesses were small businesses as of December 2024.
- Canada's only officially bilingual province — New Brunswick is the only province that is officially bilingual under the Constitution, so serving clients in both English and French is a practical requirement rather than a differentiator.
- 15% HST, one return — New Brunswick charges 15% HST — 5% federal plus 10% provincial — administered by the CRA, so clients file a single sales-tax return.
- 2.5% provincial small-business rate — New Brunswick taxes the first $500,000 of a CCPC's active business income at 2.5% provincially, with a 14% general rate above that.
- 20,631 employer businesses — New Brunswick had 20,631 employer businesses as of December 2024, of which 20,256 were small businesses.
Managing bookkeeping software across a client book in New Brunswick
A bookkeeping practice needs the month to run itself: each client's close on its own cadence, with the review step and the sales-tax return attached to the same file rather than tracked in three places.
A four-person Moncton firm growing by referral works in both official languages, which shows up less in the tax work than in the paperwork: engagement letters, document requests and deadline warnings all need a French version. Standardizing those templates once — and gating any new engagement on a signed letter — removed the awkwardest conversation the firm had, which was pricing work that had already been delivered.
How SpidNums handles it
SpidNums models the firm as clients, services and work. Assigning a typed service to a New Brunswick 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.
- Per-client month-end close projects on a recurring cadence
- Typed services with reporting frequency driving the work
- Colour-coded SLA board ranked by deadline proximity
- Assignment and live workload per bookkeeper
- Branded client requests and email digests
- CSV/XLSX client import and export
Where this goes wrong
Bookkeeping practices rarely fail at the bookkeeping. They fail at the handover points, where a file changes hands or a client changes shape.
- A client crosses the $30,000 small-supplier threshold and becomes a registrant, but the file still runs on the pre-registration checklist.
- A client's reporting period changes and the cadence stays where it was, so the next return is prepared against the old deadline.
- The review step is skipped in a busy month because it is a habit rather than a stage with an owner.
- A file waiting on client documents sits in someone's pile instead of ageing visibly on a board.
What SpidNums does not do
SpidNums is not a general ledger. Your clients' books stay in QuickBooks, Xero or whatever ledger you already use — SpidNums manages the work around them: who owns the close, what stage it is at, and what is due next.
If your firm already runs a tracking system it trusts, the honest answer is that you do not need this one. The pages on this site are written to help you decide, not to pretend every firm has the same problem.

Frequently asked questions
What is the HST rate in New Brunswick?
New Brunswick's HST rate is 15%, made up of the 5% federal component and 10% provincially. The CRA administers New Brunswick's HST.
What corporate tax rates apply in New Brunswick?
New Brunswick's provincial small-business rate is 2.5% on the first $500,000 of active business income, and its general provincial rate is 14%. Those sit on top of the federal rates — 9% federally on the first $500,000 and 15% federally on general income.
Can the software track different sales-tax filing frequencies per client?
Yes. Reporting frequency is a property of the client's assigned service, so monthly, quarterly and annual clients coexist and each generates its own recurring work. When the CRA moves a client to a different frequency, editing that one field corrects every future due date.
Is client data stored in Canada?
Yes. SpidNums hosts client data in Canada, in the ca-central-1 region, with row-level tenant isolation, an append-only audit log and staff roles that support confidential-client gating.
Does SpidNums keep the books or file the sales-tax return?
No. SpidNums is not a general ledger and does not file returns. Your clients' books stay in QuickBooks, Xero or whichever ledger you already use, and the return is filed where you file it today. SpidNums manages the work around them — who owns the close, what stage it is at, and what is due next.
