Why Startups Choose Ontario Tax Team

Building a startup is hard enough without worrying about bookkeeping, tax compliance, and financial reporting. But getting your finances right from day one is not optional. Investors expect clean books. CRA expects timely filings. And you need accurate numbers to make smart decisions about hiring, spending, and runway.

We handle the financial back office so founders can focus on building their product and growing their customer base. From setting up your cloud accounting platform to filing SR&ED tax credits, we provide the accounting infrastructure your startup needs to scale.

Whether you are a solo founder working out of a co-working space or a team of fifteen preparing for a Series A, we tailor our services to your stage and your budget. Our founder, Samer Al-Assali, has worked with dozens of startups and understands the unique financial challenges that come with building something from scratch.

What Our Clients Say

Real reviews from real clients on Google.

I'm self employed and honestly had no idea how many deductions I was leaving on the table. Samer walked me through everything expenses I never knew I could claim on my personal tax return. Thanks to his guidance, I ended up with a significantly bigger refund than I expected. If you're self-employed and filing personal taxes in Ontario, this is the team to go to. Highly recommend.

Just had my personal income tax return filed and the entire experience was seamless. I'm based in Toronto and couldn't make it into their Oakville office, but they handled everything 100% virtually: collected my documents online, walked me through every deduction I qualified for, and filed my T1 return with the CRA quickly and accurately. Communication was fast, the pricing was fair, and I filed a T4A for the first time with no headaches. If you're in Oakville (or anywhere in the GTA) looking for a knowledgeable personal tax accountant who actually responds and gets the job done right, I'd highly recommend them.
