Listed pros in Mississauga
Corporate tax filing, HST and bookkeeping for incorporated vendors, contractors and suppliers across Ontario.

Vendors get paid on other people's terms: purchase orders, net-30 invoices, marketplace payouts and holdbacks. Listed accountants on our platform keep the books lined up with what you have actually billed and been paid, and file the corporate return and HST on time.
Whether you run a business in Meadowvale, work from Port Credit or manage a logistics operation near the airport, we tailor the books and filings to how your company actually operates.
Whether you supply a retailer, sell through a marketplace, work a market stall or contract to a larger company, the same issues come up: inventory and cost of goods, HST collected versus input tax credits, and subcontractors you pay along the way.
The accountants listed here set up books that track each of those cleanly, so the year-end return is a matter of review.
Your federal and Ontario corporate return is prepared from reconciled books and filed ahead of the six-month deadline.
HST charged on your invoices is reconciled against input tax credits on purchases, and returns are filed on schedule.
Stock on hand and cost of goods sold are tracked properly, so your profit and your tax are based on real numbers.
Customer payments, marketplace payouts and holdbacks are matched to your invoices so you can see who still owes you.
Payments to subcontractors are tracked through the year and the T4A or T5018 slips are filed when they are required.
Vehicle, equipment, booth fees, shipping and supplies are reviewed so legitimate deductions are claimed with records behind them.

No, but many larger customers prefer or require an incorporated vendor with an HST number. A listed accountant can explain what incorporating would change for your tax and paperwork.
You must register and charge HST once your taxable revenue passes $30,000 over four consecutive calendar quarters. Many vendors register earlier because their customers expect an HST number and they can recover HST on their costs.
Construction businesses report subcontractor payments on T5018 slips. Other businesses generally report fees for services of more than $500 in a year on T4A slips.
Yes. Listed bookkeepers break payouts back into sales, fees, refunds and tax collected so the books agree with the marketplace reports.
Fees depend on the scope and complexity of your situation. After a free consultation we give you a clear quote before any work begins.
