Estimate US 2026 federal or UK 2026–27 non-savings employment income tax, or build a worldwide custom progressive-bracket model.
01 / CALCULATION INPUTS
Verified schedule scope: US ordinary federal income tax for 2026; England/Wales/Northern Ireland non-savings employment income for 2026–27. Custom mode is worldwide arithmetic, not verified country law. Scotland and specialized taxes are not silently assigned another schedule.
02 / RESULT & SUPPORTING CALCULATIONS
Ordinary federal income tax only. Basic nondependent, under-65, not-blind standard-deduction scope (or a user-supplied itemized deduction). State/local tax, payroll tax, AMT, capital gains, QBI and automatic special senior/tips/overtime/car-loan deductions are excluded. User-supplied AGI adjustments, itemized deductions and nonrefundable credits require independent eligibility checks.

The simplified US ordinary federal model uses IRS 2026 brackets and basic standard deductions from Rev. Proc. 2025-32. The UK model uses HMRC 2026–27 England/Wales/Northern Ireland non-savings employment bands and allowance taper. Sources were checked October 26, 2026; Scotland is not assigned this UK schedule.
State/local and payroll taxes, AMT, capital-gains rates, QBI and automatic special senior/tips/overtime/car-loan deductions are excluded. The basic standard-deduction scope is nondependent, under 65 and not blind, unless the user supplies an appropriate alternative modeled deduction. It is not total tax liability.
The standard £12,570 allowance is reduced by £1 per £2 of assumed adjusted net income above £100,000, reaching zero at £125,140. This simplified employment model assumes entered gross is adjusted net income and excludes National Insurance, savings, dividends and specialized reliefs.
Custom mode is labeled not verified country tax law. Brackets apply to income after the entered allowance and flat deductions, each subtracted once. Bands must start at zero, be sorted and contiguous, and end with a blank unbounded upper limit.
No. The effective rate is modeled tax divided by gross income. The marginal bracket rate applies to the next taxable slice; the modeled marginal rate also reflects UK allowance taper where relevant. The taper can produce a 60% modeled marginal rate without a 60% statutory bracket.
US standard and itemized deductions are mutually exclusive. Entered credits are nonrefundable and cannot produce negative tax. Amounts are parsed as cents, the UK taper retains half-cent arithmetic and aggregate bracket tax rounds half-up to cents. Actual return/PAYE table or whole-unit rounding can differ.
