Bookkeeping Services in Ontario: what every taxpayer needs to know
Ontario is Canada's largest provincial economy and the country's financial, technological, and manufacturing centre. Ontario uses HST (Harmonized Sales Tax) at 13%, combining the 5% federal GST with an 8% provincial portion. The Toronto-Waterloo Innovation Corridor is one of North America's leading technology clusters, and the province is home to most of Canada's major banks, insurers, and headquartered multinationals.
Ontario uses HST, so businesses register once with CRA for combined GST/HST collection and remittance. The province has a separate Employer Health Tax (EHT) for employers above the exemption threshold and a corporate minimum tax for large corporations. Ontario also offers refundable film/digital media tax credits, the Ontario Innovation Tax Credit, and the Ontario Production Services Tax Credit.
For bookkeeping services specifically, the Ontario environment matters because Ontario businesses must remit sales tax under the following regime: HST 13% (combines GST + provincial portion). Bookkeeping must therefore track GST/HST (and any provincial sales tax) separately from revenue so monthly, quarterly, or annual returns can be filed on time.

Common bookkeeping services problems we fix for Ontario taxpayers
Most of our Ontario clients come to us after running into one of these recurring issues:
- undeposited funds that pile up and overstate revenue
- shareholder loan account misuse that triggers s.15(2) inclusions
- sales tax recorded in income rather than as a liability
- inventory and cost-of-goods-sold treatments that overstate gross margin
- unreconciled bank accounts that hide errors and missing deposits
Every issue above has a defined CRA remedy. We document the position, prepare the supporting paperwork, file with the CRA, and represent you through any follow-up correspondence.
