calculation error

Greetings

I used TurboTax Online (Small Business), and have been using the Online version for years, generally happy with it. However this year, there was a vast difference between the 2023 TurboTax BALANCE DUE and the CRA BALANCE DUE, which was explained on the CRA Notice of Assessment as: "We changed your total payable ... because of a calculation error."

If there were errors in the TurboTax calculations, and I made no calculations, but merely input numbers from my spreadsheets... then, this is something that needs correcting for next year! The miscalculation was an unpleasant surprise of more than $600. Thankfully, I was able to catch it and pay it before the April 30th deadline, so I didn't happen to incur any CRA penalties.

Can U shed any light on this?

Thanks.

Please Note: This looks like a similar issue to the "Turbotax Errors" question from BobC .

Yes... What is being done about this?

Many thanks.

Hi Brenda,

I am experiencing the same issue as CRA is telling me Turbotax incorrectly calculated my return numbers and that my assessment is about $850 higher than reported by TurboTax. This is obviously very upsetting, especially as they are unable to tell me where the error is. Is this something you can assist me with?
