Line 48200 on your Canadian T1 return is the total of every amount credited against your tax bill for the year: income tax already withheld from your pay, refundable federal credits, and provincial or territorial credits. The Canada Revenue Agency subtracts this total from your total tax payable on Line 43500, and the difference is either your refund or what you owe. For most employees, the withholding piece alone is large enough to matter, and any refundable credits you qualify for stack on top.
What Feeds Into Line 48200
Line 48200 is a sum, not a standalone calculation. Several lines from the final section of your return flow into it:
- Line 43700 — total income tax deducted at source, taken from box 22 of your T4 slips and similar boxes on other information slips.1Canada Revenue Agency. Line 43700 – Total Income Tax Deducted
- Line 45300 — Canada Workers Benefit.
- Line 45350 — Canada Training Credit.
- Line 45355 — Multigenerational Home Renovation Tax Credit.
- Line 47900 — provincial or territorial credits calculated on Form 479 or Form 428.
For a typical employee, Line 43700 is the largest component by a wide margin. The refundable credits are what make Line 48200 valuable for people whose withholding is small or zero.
Why Refundable Credits Matter on This Line
Non-refundable credits, like the basic personal amount, are already worked into Line 43500 before you get to Line 48200. They can reduce tax owing to zero, but any leftover amount disappears.
The credits sitting on Line 48200 behave differently. They can push your balance below zero, which means the government pays you even if you had no tax liability. That’s why the Canada Workers Benefit can produce a payment for a low-income filer who had nothing withheld during the year.
The Refundable Credits You Might Claim
Canada Workers Benefit (Line 45300)
The Canada Workers Benefit supports individuals and families with low working income. For the 2025 tax year, the maximum basic amount is $1,633 for single individuals and $2,813 for families, indexed annually.2Canada Revenue Agency. Line 45300 – Canada Workers Benefit (CWB) The credit phases in above a minimum working income and phases out at higher incomes, with thresholds that vary by province or territory.3Canada.ca. Canada Workers Benefit – Who Is Eligible The calculation happens on Schedule 6.4Canada.ca. Canada Workers Benefit (CWB) – How to Claim
If you received advance CWB payments during the year, they are reported on Line 41500 through Schedule 6, which reconciles the advances against your final entitlement.5Canada Revenue Agency. Line 41500 – Advanced Canada Workers Benefit (ACWB) Missing this step triggers a reassessment.
Canada Training Credit (Line 45350)
The Canada Training Credit covers eligible tuition and fees at recognized institutions and is refundable, meaning it can produce a payment rather than only reducing tax.6Canada.ca. Line 45350 – Canada Training Credit (CTC) The amount you can claim is capped by your accumulated training credit limit, which the CRA tracks on your Notice of Assessment. The claim is supported by the T2202 certificate your school issues.7Canada.ca. Education Deductions and Credits
Multigenerational Home Renovation Tax Credit (Line 45355)
This credit is for families who renovate a home to create a self-contained secondary suite for a senior or an adult eligible for the disability tax credit. You can claim up to $50,000 in qualifying expenses at a credit rate of 14.5%, for a maximum of $7,250 per qualifying renovation.8Canada.ca. Line 45355 – Multigenerational Home Renovation Tax Credit (MHRTC) The renovation has to create a genuinely separate living space and the qualifying relative has to actually live there. Keep dated receipts for labour and materials that show the nature of the work, since cosmetic upgrades don’t qualify.9Canada Revenue Agency. Multigenerational Home Renovation Tax Credit (MHRTC) – How to Claim
Provincial and Territorial Credits (Line 47900)
Where you lived on December 31 of the tax year determines what refundable provincial or territorial credits you can claim. Residents of Ontario, Manitoba, British Columbia, Yukon, the Northwest Territories, and Nunavut typically use Form 479. Other provinces use Form 428 for items like a volunteer firefighter tax credit or an investor tax credit.10Canada Revenue Agency. Federal Income Tax and Benefit Guide – Provincial or Territorial Credits The total from either form goes on Line 47900 and feeds Line 48200. Tax software normally selects the correct form based on your province.
One boundary worth noting: the Canada Carbon Rebate for individuals was closed as of March 15, 2025, with no further quarterly payments after April 2025.11Canada Revenue Agency. Closed – Canada Carbon Rebate (CCR) for Individuals It will not appear on a 2026 return.
How Line 48200 Produces a Refund or Balance Owing
Line 43500 is your total tax payable, federal plus provincial or territorial, before Line 48200 is applied.12Canada Revenue Agency. Line 43500 – Total Payable The comparison is simple:
- If Line 48200 is greater than Line 43500, the difference is your refund, reported on Line 48400.13Canada Revenue Agency. Line 48400 – Refund
- If Line 43500 is greater, you owe the difference, reported on Line 48500.
For most employees, the withholding on Line 43700 alone pushes Line 48200 above the total payable, which is why a refund is common even before any refundable credits are added.
When the CRA Redirects Your Refund
A refund calculated from Line 48200 isn’t guaranteed to reach your bank account. The CRA can automatically apply it to outstanding government debts, including overdue tax, Canada Student Loans, Employment Insurance overpayments, and CPP overpayments, and the same offset extends to debts owed to other federal, provincial, and territorial programs.14Canada.ca. How We Automatically Apply Credits and Refunds to Your Debt Any amount taken this way appears on your Notice of Assessment. There is no way to opt out if you have qualifying debts.
If the CRA Reduces the Amount on Line 48200
After processing, the CRA can reassess your return and lower Line 48200 if it disputes a credit or spots a calculation error. Your Notice of Assessment will show the change. If you disagree, you have 90 days from the date the notice was sent to file a Notice of Objection.15Canada Revenue Agency. Objections and Appeals If the objection doesn’t resolve the matter, you can appeal to the Tax Court of Canada.16Canada Revenue Agency. Objections, Appeals, Disputes, and Relief Measures
Keep every receipt and supporting document behind the credits you claimed for at least six years from the end of the tax year they relate to. If you filed late, the six-year clock starts from the date you actually filed. If you’ve filed an objection or appeal, hold everything until the matter is fully resolved or the six-year period ends, whichever is later.17Canada.ca.
