    One of the best managed Accounting Services. Continuous tax updates and tips are provided to the…read moreclients. After getting disappointed by other services I and my family switched to them. They did a detailed review of our taxes and gave valuable suggestions while filing our returns since then we never looked back. Overall a great service provider. I wish them great success with their client base.

    If you are using this company to prepare your tax return, please ensure that you are reading the…read morefine print because there are hidden charges. I was told that tax return for self employed individuals cost $80 when I booked my appointment over the phone.By the time they were done with me, I paid $145. Here's their explanation: $40 for personal tax return + $80 for self employed tax return + $20 for having transportation/vehicle expenses claim. Lucky for me, I did all my receipt and expenses calculations already, otherwise that would have cost me more. I was surprised they didnt start charging for every paper clip and staple they used to prep my tax return!! A bookeeper preps your paperwork, not an accountant. The accountant in the office DOES NOT check the paperwork prior to filing. Next time, I will just purchase a turbotax software and do it myself. Filing with Trehan Accounting office is a complete RIP OFF. PS. The google reviews I found online were written by their own office staff. The fellow who wrote a stellar review on Google Review was actually the bookeeper that did my tax return. What a bunch of crooks!

    Absolutely the most unethical and lazy bookkeeping company I've ever dealt with. The owner, Chris…read morerefused to acknowledge their multitude of mistakes on my file... confirmed by two other bookkeeping companies... He absolutely REFUSED to even hear the concerns I had with their mistakes costing us over $25,000 dollars in overpay on payroll for a small staff. Also, charging hundreds of dollars for doing 5 employee payroll calculations per month (takes me 15 minutes to do it myself)... Chris refused to have a discussion claiming I treated his staff poorly- I have no problem admitting that the last few encounters were horrible, as they kept costing us more and more money, charging more, and would not address the concerns of paying an additional 5% holiday pay on every person's paycheque... in addition to the stat holidays and vacation pay ( totally separate)... When I asked them to review our payroll process 4 years ago, they confirmed it was correct... every year, I'd express how unusually high the deductions were... I asked nearly two years ago for them to again look into this... and last summer they again pacified my concerns reassuring me it's correct. I don't know one other company that has an additional 5% of previous month earnings added to staff income, over and above the usual earnings, and calculating usual deductions. How can they claim to be professional bookkeeping service, especially when they refuse to acknowledge their mistakes? I hope this review helps others make an informed decision before trusting this company.

    Although friendly the person who does you initial consult gives the impression that you are in good…read morehands. Used this service for 3 months and then jumped ship to a far superior service. Mistake after mistake that I'm still discovering. Shareholder loans entered and matched to an online banking entry in the name of a customer! Unacceptable. The invoices are high compared to the service I use now (who is thorough, accurate and professional) highly recommend going anywhere else. I wasted a lot of money, time and trust on what I thought was going to be a useful choice.
