United Kingdom version
How it works
Estimate ordinary annual employment income tax with dated country rules, separating deductions, basic credits, Canadian provincial calculations, Irish USC and separately entered other local tax.
This is the United Kingdom planning view, with monetary inputs and outputs in GBP. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.

Formula
Dated national/provincial marginal tax − supported automatic and entered credits + entered other local tax; Irish USC is separate.
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.
Read the inputs before calculating
- Annual gross income: Enter the quantity described by the label.
- Additional deductible amount (not a tax credit): Enter the quantity described by the label.
- Additional verified nonrefundable national credits: Enter the quantity described by the label.

- Other state/local income tax not automatically included: Enter the quantity described by the label.
Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.

Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Planning calculation, not a tax return, benefit decision, credit approval or legal opinion. No eligibility is inferred from a numeric result.
- Only the stated tax year and expressly supported rule components are included. Entered amounts require independent verification.
- UK: 2026/27 non-savings, non-dividend income, with the standard Personal Allowance and its taper. The separate NI result uses the selected category. Marriage Allowance, pension annual-allowance charges and other special reliefs are not inferred.
- Reference period: 2026-04-06 through 2027-04-05. Income/payroll references checked 2026-09-25.

Frequently asked questions
What does this Income Tax Planning result represent?
Estimate ordinary annual employment income tax with dated country rules, separating deductions, basic credits, Canadian provincial calculations, Irish USC and separately entered other local tax. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified United Kingdom prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is GBP; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Planning calculation, not a tax return, benefit decision, credit approval or legal opinion. No eligibility is inferred from a numeric result. Only the stated tax year and expressly supported rule components are included. Entered amounts require independent verification.
Can I compare or share different assumptions?
