Did you claim the CWB, and if yes, were you a student?

No, I was not a student.

I also had a calculation error reported by the CRA, the refund was lower than what was calculated by TurboTax. The area is the federal tax area. I have used this program for many years and help other family members with filing so this concerns me that it is not accurate or is the issue on the CRA side?

@maliciousgoose103 To be eligible for the Canada Workers Benefit (CWB), you must be a Canadian resident, at least 19 years old (or younger if living with a spouse/partner/child), earn working income, and have a net income below the thresholds set for your province or territory. If you do not meet the eligibility criteria, CRA will automatically remove the Tax credit for you.

I qualified for the CWB last year. I have qualified for it this year as well.

CWB is not the problem. I did a quick check with your free estimator online and the amount matched my CRA refund. There is an error in the desktop Turbo Tax.

If there is a difference between what TurboTax calculated and what the CRA calculated, then your NOA should say what the CRA changed. Did the NOA say that the CWB was removed or reduced? Or did they make a change that made you ineligible for the CWB (ex: too much income)?

As stated previously this is not related to CWB. This is what was stated on the NOA;

We changed your total payable from $********** to $********* because of a calculation error.

I have removed the values for privacy.

I understand that.. I assumed CWB as that was the amount difference between the calculation. I am using TurboTax online so, it is not a desktop issue. I am trying to find out the issue.. Is it Turbo Tax if so, do they guarantee the difference when it is the mistake of TurboTax. I had done my mothers and my girlfriends with no issues in their calculations. So, it is not the software either.

Your total payable is the amount of federal and provincial or territorial taxes that you owe before you subtract your total credits (line 48200). It also includes, if applicable, CPP contributions payable on self-employment and other earnings (line 42100), Employment insurance premiums payable on self-employment and other eligible earnings (line 42120), social benefits repayment (line 42200)

Double-check the amounts you entered on your T-slips to make sure that they were correct and entered in the proper boxes.

How do I submit a claim under the TurboTax 100% Accurate Calculations Guarantee?

Thank you for choosing TurboTax.

I fled for my sil and last year’s return had a “calculation error” resulting in her receiving a lower refund. The difference was in federal tax payable. I have gone line by line and it seems the error is on CRA’s part. I just did her her 2024 return and her refund is lower than filed again. I haven’t seen the NoA yet but I’m betting there’s another supposed calculation error. I do about 10 family members and hers is the only one that this has happened with. I’ll be writing to them for a more detailed explanation.

Same for my sil. I’ve gone line by line and the only difference is in CRA’s calculation of federal tax. THEY calculated it incorrectly as far as I can tell so I’ll be writing to get an explanation.

In my sill’s case the NoA just said the difference was due to a calculation error. I manually calculated the changed line (federal tax) and CRA’s amount is incorrect. That was 2023 T1. I believe they’ve done it to get 2024 return as well.

I just got lost over $1000 of my 2025 tax refund because Turbotax did not calculate my Canada workers benefit correcting.

We are dealing with this in the 2025 tax year. CRA shows Turbotax calculated line 42000 incorrectly. Net Federal tax. Thing is, I think Turbotax is correct.

My daughter makes less than the basic personal exemption. I follow the steps in the T1 to calculate her federal taxes and it makes sense. Federal rate of 14.5 % on her taxable income. Non refundable tax credits are also 14.5%. Basic personal exemption is almost double her income. NRTC's are almost double her tax calculated so when you subtract it is negative which should go to zero. Line 126.

This is a huge deal for a broke kid. CRA is impossible to talk to. She is challenging. Anyone else experience this? CRA got a bug? Turbotax doing calculation wrong?

That is the error message we got too. All numbers sync perfectly except the Net Federal Tax. Thing is, i can calculate Turbotaxes number but not CRA number. I think CRA has a bug.

My daughter is having the exact same issue with line 42000. It’s reducing her credit by almost $1000. I have also gone line by line and can’t see any errors
