Quick Answer

What does business tax preparation include in Canada? Business tax preparation includes preparing and filing your T2 corporate income tax return, GST/HST (and QST for Quebec businesses), identifying all eligible business deductions, researching applicable tax credits like SR&ED, and ensuring compliance with CRA and Revenu Québec requirements. The goal is minimizing your legitimate tax liability while ensuring every deadline is met.

Why Professional Tax Preparation Pays for Itself

Canadian business taxes are complex — and DIY approaches often miss significant deductions or create CRA compliance risks. A missed SR&ED claim alone can cost a growing tech company tens of thousands in uncaptured credits. An incorrectly filed GST/HST return can trigger costly penalties. Our tax specialists ensure every deduction is identified, every credit is captured, and every filing is submitted on time — making the cost of professional tax preparation one of the best ROI decisions your business can make.

Tax FAQs

Business Tax Questions Canadian Owners Ask Most

When is the T2 corporate tax return due in Canada?
The T2 return is due 6 months after your fiscal year-end. However, taxes owing are due just 2–3 months after fiscal year-end (2 months for most corps, 3 months for CCPCs claiming the small business deduction). Filing late results in a 5% penalty plus 1% per month on any balance owing. ATS ensures you never miss these deadlines.
What's the difference between T1 and T2 returns?
A T1 is the personal income tax return filed by individuals. A T2 is the corporate income tax return filed by incorporated businesses. If you run an incorporated business, your corporation files a T2 annually. You personally file a T1 to report your salary, dividends, and other personal income. ATS handles both.
How much does small business tax preparation cost?
ATS T2 corporate returns start at $799/year. Cost depends on business complexity, number of transactions, and how organized your books are. Clients who use ATS monthly bookkeeping pay significantly less at tax time because their records are already clean and complete — reducing the time needed for tax prep.
What is SR&ED and could my business qualify?
SR&ED (Scientific Research & Experimental Development) is a federal tax incentive providing credits of 15–35% on eligible R&D expenditures. Even failed experiments qualify if you were trying to advance technology. Tech companies, manufacturers, and businesses developing new processes often qualify without realizing it. ATS identifies SR&ED opportunities as part of your tax review.
What is the Quebec QST and how is it different from GST?
QST is Quebec's 9.975% provincial sales tax, administered separately from federal GST (5%) by Revenu Québec. Businesses operating in Quebec must register, collect, and remit both taxes. Combined, the total sales tax rate in Quebec is 14.975%. ATS handles both GST and QST filings for Quebec businesses.
Can ATS help with a CRA audit?
Yes. ATS provides full CRA audit support — reviewing the audit request, gathering and organizing supporting documentation, preparing written responses to CRA inquiries, and representing your interests. Having accurate, well-documented books from day one is the single best defence against costly audit findings.
