Rates & sources
UK tax rates and thresholds, as published by HMRC. Scotland and Wales have devolved rates for income tax and property transactions.
Source: HMRC — Tax rates — figures refreshed at the start of each tax year.
When to use this calculator
- Before accepting a pay change, bonus, pension contribution, or salary-sacrifice option.
- When you want to compare employed, self-employed, or dividend-based income scenarios.
- When you need a simple take-home estimate before running payroll or filing returns.
- When you are approaching the £100,000 income level and want to understand the personal allowance taper effect.
- When you are planning a salary sacrifice arrangement and need to see the net pay impact before agreeing terms.
A realistic Canada planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
Annual Employment Income (CA$)
CA$65,000
RRSP Contribution (CA$)
CA$250 per month
After entering these figures, review federal tax, ontario tax and total tax together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
How to read your results
Federal Tax
Review this figure alongside your gross income so you can understand the true cost of deductions and plan around any thresholds before the tax year closes. If the figure looks higher than expected, check whether any pension or gift-aid contributions could reduce your taxable income.
Ontario Tax
Review this figure alongside your gross income so you can understand the true cost of deductions and plan around any thresholds before the tax year closes. If the figure looks higher than expected, check whether any pension or gift-aid contributions could reduce your taxable income.
Total Tax
Review this figure alongside your gross income so you can understand the true cost of deductions and plan around any thresholds before the tax year closes. If the figure looks higher than expected, check whether any pension or gift-aid contributions could reduce your taxable income.
Net Take-Home
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Effective Rate
The effective rate lets you compare options on a true like-for-like basis rather than being misled by different compounding periods or fee structures. Use it to cut through headline marketing rates when shortlisting providers or products.
Method & assumptionsAuthoritative sources
This calculator applies the 2024 federal and Ontario provincial income tax brackets. Federal tax uses the basic personal amount of $15,705 and five bracket rates (15%, 20.5%, 26%, 29%, and 33%). Ontario provincial tax uses the basic personal amount of $11,865 and five bracket rates (5.05%, 9.15%, 11.16%, 12.16%, and 13.16%). The Ontario surtax — an additional charge of 20% and 36% on Ontario tax above specified thresholds — is not modelled in this calculator; higher earners should allow for modest additional provincial tax. CPP and EI premium deductions are also not included, as these depend on employment status and annual earnings; both reduce net take-home pay further.
RRSP contributions entered are deducted from taxable income before both federal and provincial brackets are applied. The 18% of prior-year earned income limit is approximated using current-year income. For precise RRSP room, consult your most recent Notice of Assessment from CRA. This calculator is intended as a planning tool; always file an accurate T1 General Return and seek advice from a CPA or registered tax professional for complex situations involving rental income, capital gains, foreign income, or business income.
Common mistakes
- !Entering gross income when you really want take-home pay, or vice versa.
- !Ignoring pension contributions, deductions, or local tax rules that change the result.
- !Comparing monthly and annual figures without standardising them first.
- !Overlooking the National Insurance threshold changes that apply mid-year when rates or bands are adjusted in a Budget.
- !Assuming a salary sacrifice benefit reduces take-home pay by the full gross amount, rather than only the after-tax cost.
What to do next
- Check the same scenario with related pay or deduction calculators to see the full picture.
- Keep a copy of the assumptions you used so you can compare next tax year or pay period accurately.
- Read the related guides below if you are choosing between multiple income or deduction options.
- If you are self-employed, run the self-employment tax calculator alongside this result to compare the net position against employed income.
- Check whether increasing your pension contribution by even one or two percent changes the take-home significantly — use the pension calculator next.
