Frequently Asked Questions

Does this account for provincial differences in holdback release timing?

Yes, the prompt specifies compliance with your selected province's legislation. However, always verify current regulations as some provinces (like Ontario post-2019) have different rules for substantial performance calculation and holdback release compared to others.

Can I use this for residential construction projects?

Yes, but note that some provinces have different holdback rules for residential projects under certain thresholds, and consumer protection laws may impose additional requirements on payment schedules for home renovations.

How does this handle the new Prompt Payment legislation?

The prompt incorporates Prompt Payment Act requirements for provinces that have enacted them (Ontario, Saskatchewan, Alberta, BC). It includes proper notice periods, dispute resolution timelines, and mandatory interest rates for late payments.

Should I include HST/GST on the holdback amount?

Generally, tax is calculated on the full invoice amount before holdback deduction, but the cash holdback is the net amount. The prompt addresses proper tax treatment, but consult your accountant as some situations (like holdback release timing) can affect input tax credit claims.
