Sample Tax Check Reports
See exactly what a Return Check and a Letter Check report look like before you pay. Made-up people, real 2025 math, every finding explained.
If I was going to pay for a tax check, I would want to see what I get first. So here it is. Below are two reports exactly as our software lays them out: one Return Check and one Letter Check.
The people are made up and so are the numbers, but the math is real. Every dollar figure on this page was worked out with the 2025 federal and Ontario rates (2024 for the letter), and you can check it with our income tax calculator.
Sample Return Check Report
The set-up: a single parent in Ontario with two jobs, a daughter in daycare and a move for work. She uploaded her return, both T4 slips and last year's notice of assessment, and answered a few questions. This is what came back. Her real report would also have a section listing every line and slip we read, so she could check we read them right.
Return Check: standard return · Ontario · tax year 2025 · checked April 2, 2026
One thing must be fixed before you file: a T4 from your part-time job is not on the return. Two deductions you are entitled to are not claimed, worth about $730 together. Everything else we checked lines up with your slips.
Fix before you file (1)
Line 10100 · Checked by our calculator
Your return shows employment income of $61,250. Your two T4 slips add up to $64,250: $61,250 from Northshore Logistics and $3,000 from Harbour Hardware. The Harbour Hardware T4 is not on the return. CRA gets a copy of every T4, so its matching program will find this. Adding it means about $890 more tax, less the $310 already deducted on that slip (box 22), so roughly $580 more to pay.
What to do: Add the Harbour Hardware T4 in your tax software before you file. Make sure its box 22 tax goes on line 43700 too.

Line 21400
You told us you paid $1,850 to a licensed daycare for your daughter, age 4, while you worked. Nothing is claimed on line 21400. As the only parent in the home, you claim it. At your top tax rate of about 29.65%, that is worth about $550.
What to do: Claim $1,850 on line 21400 with form T778.
Keep: The daycare receipts with the provider's name and business number.

Line 21200 · Checked by our calculator
Box 44 of your Northshore Logistics T4 shows $612 in union dues. Line 21200 on the return is empty. Union dues are a deduction, worth about $180 at your top rate.
What to do: Enter $612 on line 21200.
Keep proof ready (1)
Line 21900
You claim $4,200 for moving to Barrie for your new job. The claim looks reasonable. CRA picks moving claims for review more often than most, and it will ask for proof.
Keep: Receipts for the movers and travel, and something that shows your new home is at least 40 km closer to the new job than the old one was (a map printout is fine).

Checked and fine (2)
Line 20800 · Checked by our calculator
You deducted $5,000. Your 2024 notice of assessment shows a 2025 limit of $9,840.
Lines 30800 and 31200 · Checked by our calculator
The CPP and EI amounts on the return match your Northshore Logistics T4 to the cent. When you add the Harbour Hardware T4, your tax software adds its CPP and EI to these lines for you.
Who checked this: our software read your documents, our calculator checked the arithmetic and slip totals, and a second AI review checked every finding. No accountant has reviewed this report.

Sample Letter Check Report
The set-up: a CRA review letter asked for medical receipts, life got busy, the deadline passed, and a notice of reassessment showed up. She uploaded the notice and wrote two lines about what happened.
Letter Check · Notice of reassessment, tax year 2024, dated March 18, 2026
What CRA is saying
CRA has taken away your medical expense claim of $3,150 (line 33099). It wrote to you in January asking for the receipts. It did not get them by its deadline, so it removed the whole claim.
Is CRA right?
On the paperwork, yes: no receipts arrived, so CRA was allowed to remove the claim. On the money, probably not. You told us you have receipts for dental work, physiotherapy and prescription glasses that add up to the $3,150 you claimed. All three are eligible medical expenses. Once CRA sees the receipts, the claim should go back on.
What changed
| Item | As filed | As changed | Tax effect |
|---|---|---|---|
| Medical expenses (line 33099) No receipts received by the review deadline | $3,150.00 | $0.00 | $282.71 |
How the $282.71 works out: your net income was $58,000, so the first $1,740 (3%) of medical expenses does not count. The other $1,410 earns a 15% federal credit ($211.50) and a 5.05% Ontario credit ($71.21).
What to do, in order
- This week: Scan all three receipts. Send them through Submit documents in My Account with a short note: “Please reconsider my 2024 reassessment dated March 18, 2026. The receipts you asked for are attached.” Quote the reference number from the notice.
- Pay or not: Paying the $282.71 now stops interest from growing. If CRA puts the claim back, you get the money back with interest.
- If no answer by June 1, 2026: File a notice of objection before June 16, 2026, with the same receipts. That keeps your right to dispute the reassessment, whatever happens with the first request.
Documents to gather
- Dental invoice and proof of payment: $1,900
- Physiotherapy receipts: $840
- Prescription glasses receipt: $410
- The notice of reassessment, for the reference number

What These Reports Are, and What They Are Not
1. They are a second set of eyes. Our software reads your documents, a calculator checks every number it can, and a second AI review throws out anything it cannot back up.
2. They are not an accountant. Nobody at CanadianTaxes.ai looks at your report before you do. If something is big, messy or scary, the report says so and tells you to get a professional.
3. They do not file anything. You stay in charge of your return and of anything you send to CRA.
4. We back the Return Check. If CRA later changes your return for something on our checklist that we missed, we refund your fee.
How do we know the software catches what it should? We feed it fake returns with mistakes we planted on purpose. Here is how we test it, and the latest results.
