Surrey construction: T5018, holdbacks and WorkSafeBC in one year end

5.0 from 20 Google reviews

By EverStone CPA · Published September 2026 · 6 min read

Quick answer: A Surrey construction corporation’s year end is decided by three filings that a service business never touches. T5018 slips report what was paid to subcontractors, and the CRA matches them. Lien holdbacks — the portion of each progress payment withheld under the Builders Lien Act — sit on the balance sheet as receivables and payables and have to line up with revenue recognised. And every subcontractor paid needs a WorkSafeBC clearance letter on file, or the company can become liable for the sub’s premiums. Get those three right and the T2 follows.

T5018: the slip contractors meet by letter

Any business whose main activity is construction and that pays subcontractors for construction services has to report those payments on T5018 slips, filed with a summary within six months of the fiscal year end. The CRA uses them to match the subcontractor’s reported income, so late or missing slips are found. The slip requires the sub’s business number or SIN, which is easier to collect at the first invoice than at year end. Our holdbacks guide and the Surrey contractor page go into the mechanics.

Holdbacks on the balance sheet

Under BC’s Builders Lien Act a portion of each progress payment is held back until the lien period runs. For the contractor that is money earned but not yet collectible — a holdback receivable — and for the payments it makes to its own subs, a holdback payable. Both belong on the year-end balance sheet, consistent with the revenue recognised to date, and the GST on a held-back amount has its own timing. Bonding companies read the holdback and work-in-progress lines before anything else; financial statement preparation in Surrey covers how EverStone presents them.

WorkSafeBC clearance

A prime contractor that pays a subcontractor without a valid clearance letter can be assessed for the sub’s unpaid WorkSafeBC premiums. The letter is free and takes minutes to check online; the failure is not checking, or checking once and not again for a sub used all year. Clearance status at each payment date is the standard, and the file should show it.

Employee or subcontractor, decided before the first cheque

Surrey’s construction base runs on subs, and the CRA’s view of whether a given worker is really an employee does not depend on the label. Control, tools, chance of profit and integration decide it. The decision changes which slip is issued (T4 or T5018), whether source deductions are owed and who carries WorkSafeBC. See subcontractor vs employee for trades.

Common questions

Frequently asked

Do I have to file T5018s if I only used two subs?+
If construction is your main business activity and you paid subcontractors for construction services, yes, regardless of how many. The threshold is about your activity, not the count.
Are holdbacks income when I invoice them or when I collect them?+
They are recognised with the revenue they belong to and shown as a receivable until collectible; the GST on a holdback becomes payable on its own timing under the excise rules. The accounting and the GST do not move together, which is why the books track holdbacks separately.
What happens if a sub I paid had no WorkSafeBC coverage?+
WorkSafeBC can assess you for premiums on the amount you paid that sub. A clearance letter obtained before each payment is what prevents it.
