Questions
Sage 50 sales tax — FAQs
How do I set up GST/HST in Sage 50?
In Sage 50 you create tax codes linked to tax authorities, then assign those codes to your items and customers so the right rate applies automatically. We configure the GST/HST codes, rates, and accounts correctly for your province and business, so what you collect and pay posts to the right places.
Can Sage 50 handle both Canadian and US sales tax?
Yes. Sage 50 supports multiple tax authorities and codes, so you can track Canadian GST/HST and PST alongside US state and local sales tax in the same file. That makes it well suited to cross-border businesses, and we set up the codes so each sale is taxed correctly for where it happens.
Do you file my sales-tax returns for me?
We prepare and reconcile the sales-tax figures in Sage 50 and coordinate the filing and remittance with you or your authorized filer. We are not acting as your authorized tax filer — our role is to make sure the numbers are accurate and the return is ready and on time.
My sales-tax report doesn't match my return — why?
Mismatches usually come from transactions assigned the wrong tax code, manual edits to tax amounts, or timing differences between the report period and what was filed. We trace the difference, correct the coding, and reconcile the report to your return so the numbers tie out.
Can you fix PST or a tax code that was set up wrong?
Yes. We review your existing tax codes, authorities, and the accounts behind them, correct anything set up wrong, and reassign codes on items and customers so future transactions are taxed correctly. Where needed, we also help clean up prior transactions that used the wrong code.
