Tax Return Optimizer
Most calculators tell you what you owe. This one tells you what to do about it. Enter your income, what was already withheld, your registered-account room, and your giving, and it estimates your refund or balance owing, then shows the moves that lower your tax this year, with a few scenarios side by side. Plain-language guidance for the everyday filer, not complicated tax work. It is an estimate, not advice.
Your Income
Start with the income you expect to report. Salary numbers come off your T4. Leave anything that does not apply at zero.
Investment Income
Only the kind held outside an RRSP or TFSA is taxed. If everything you own is inside a registered account, leave these at zero.
Tax Already Paid
This is how the tool knows whether you get a refund or owe a balance. It is your income tax withheld, not CPP or EI.
Registered Accounts
RRSP and FHSA contributions lower your taxable income. A TFSA does not, but it matters for the recommendations. Find your room on your CRA Notice of Assessment or in My Account.
Giving
Gifts to your church and registered charities earn a donation tax credit. Enter the total you gave this year.
Your Estimated Refund
An estimate for planning only, not tax, legal, or financial advice. Your actual return will differ.
What the Numbers Suggest
Tailored to the income and bracket you entered. General guidance, not personal tax advice.
Scenarios Side by Side
The same income, different contribution choices. Tax saved is measured against contributing nothing.
| Scenario | Contribution | Refund / (owing) | Tax saved |

How the Tax Is Built

Estimates use reviewed 2026 federal and provincial rates, the basic personal amount, CPP/QPP, EI, the dividend gross-up and tax credit, the 50% capital gains inclusion, and the charitable donation credit. It does not model every credit (medical, childcare, tuition, age, spousal, and others), so your real return may differ.
Please read: this is not advice
This tool is for education and planning only. It is not tax, legal, accounting, or financial advice, and using it does not create any advisory relationship. Dan Taylor is a pastor, not a licensed tax professional, and the figures here are estimates, not a substitute for professional advice or for filing a return.
It models the most common income types, deductions, and credits using reviewed 2026 assumptions. It does not capture every credit, deduction, or provincial detail, and it can be wrong for your situation. Income tax is also separate from CPP, QPP, and EI: the refund or balance shown compares income tax against income tax withheld only. If you are self-employed, you also owe CPP or QPP on that income, estimated at the full (double) rate and reported on your return, which is not included in the refund or balance above.
Before you file or make a significant decision, confirm the numbers with a licensed tax professional or CRA-certified software, and check current limits on the assumptions page. You are responsible for your own filing.
