Nova Scotia HST: 15% rate, point-of-sale rebates and CRA filing

Nova Scotia point-of-sale rebates — built into the HST

Unlike most HST provinces, Nova Scotia maintains several point-of-sale rebates that reduce the effective HST rate on specific categories — children's clothing and footwear under $94 per item, children's diapers, feminine hygiene products, books (all books — fiction, non-fiction, textbooks, dictionaries — but not magazines), and the first $750,000 of new-home construction. These rebates are administered at point of sale by the seller, who claims the rebated amount back from the CRA on the GST/HST return.

Practically, a Halifax bookstore selling a $20 novel charges HST on the federal 5% portion ($1) but rebates the 10% provincial portion (saving the buyer $2). The customer pays $21, the seller remits the federal $1 to CRA, and claims the $2 provincial rebate on Line 111 of the GST/HST return. HelloBooks handles the rebate-line splits automatically — tag inventory categories (children's items, books) in the item master and the right HST + rebate logic flows through to the return.

The new-housing rebate — Nova Scotia specifics

Nova Scotia's new-housing rebate provides relief on the first $375,000 of the new-home purchase price (vs Ontario's $400,000). The rebate is 18.75% of the provincial 10% HST portion paid on the first $375,000 — capped at $7,031.25. For purchasers, this rebate is typically claimed via the builder reducing the contract price; the builder then claims back the rebate from CRA. For owner-builders, the rebate is claimed directly via Form GST190 within two years of substantial completion. The rate of the rebate (18.75%) is unique to Nova Scotia — Ontario uses 75% on a different cap structure, leading to materially different effective rates between provinces on new-home transactions.

Filing cadence and the Halifax port logistics angle

Filing frequency mirrors the federal HST/GST framework: annual under CAD 1.5M revenue (with quarterly installments if owing), quarterly for CAD 1.5M-6M, monthly above CAD 6M. Returns via GST/HST NETFILE due end of next month for monthly/quarterly filers, 3 months post year-end for annual filers. Halifax-based importers benefit from filing aligned with Customs Self-Assessment (CSA) program if registered — CSA importers can defer GST/HST on imports until the consolidated return rather than paying at the border, freeing up working capital on inventory in transit.
