Quick Answer

This tax calculator estimates annual income tax for a single resident employee by applying the progressive brackets of the country that matches your selected currency — the US, UK, Canada, Australia, India, Singapore, Japan or the UAE — to income after that country's standard allowance. For example, a single US filer earning $85,000 in 2026 pays $9,870 in federal tax (11.6% effective) after the $16,100 standard deduction, and a UK earner on £60,000 in 2026/27 pays £11,432. State or provincial tax is a flat rate you enter, most credits and itemized deductions are ignored, and euro users are asked to pick a specific country's currency.

Core Equation

Tax = progressive brackets applied to (income − allowances), then country extras:
  US 2026: income − standard deduction ($16,100 single / $32,200 joint / $24,150 head) → 10%–37% brackets; + state rate × income
  UK 2026/27: £12,570 personal allowance (reduced £1 per £2 over £100,000) → 20% to £37,700, 40% to £125,140, 45% above
  Canada 2026: 14% / 20.5% / 26% / 29% / 33% (thresholds $58,523 / $117,045 / $181,440 / $258,482) minus 14% credits for the $16,452 basic personal amount, Canada employment amount, base CPP and EI; + provincial rate
  Australia 2026-27: 0% to $18,200, 15% to $45,000, 30% to $135,000, 37% to $190,000, 45% above; + 2% Medicare levy
  India FY 2026-27 new regime: ₹75,000 standard deduction; 0/5/10/15/20/25/30% slabs every ₹4 lakh; no tax up to ₹12 lakh taxable (87A); + 4% cess
  Singapore YA 2027: 0% on first $20,000 rising to 24% above $1,000,000, after CPF relief
  Japan 2026: salary − employment income deduction − social insurance − basic deduction → 5%–45% × 1.021; + 10% resident tax
Effective Rate = Total Tax / Income × 100

Worked Example: Tax Calculator 2026

US, single, $85,000 (state rate 0%): Taxable = $85,000 − $16,100 = $68,900 10% × $12,400 + 12% × $38,000 + 22% × $18,500 = $1,240 + $4,560 + $4,070 = $9,870 (effective 11.6%) UK, £60,000: Taxable = £60,000 − £12,570 = £47,430 20% × £37,700 + 40% × £9,730 = £7,540 + £3,892 = £11,432 (effective 19.1%) Australia, $100,000: 15% × $26,800 + 30% × $55,000 = $20,520 + Medicare levy $2,000 = $22,520 (effective 22.5%)

Frequently Asked Questions — Tax Calculator 2026

Which country's tax rules does the calculator use?

The rules follow the currency selected in the site header: USD = United States, GBP = United Kingdom, CAD = Canada, AUD = Australia, INR = India, SGD = Singapore, JPY = Japan and AED = UAE. The result names the rule set and tax year applied. EUR shows a note instead, because each Eurozone country has its own income tax.

What is the US standard deduction for 2026?

For tax year 2026 the US standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household (IRS Rev. Proc. 2025-32). It is subtracted before the brackets apply: a single filer earning $85,000 is taxed on $68,900, giving $9,870 of federal tax. Itemize only if your deductions, such as mortgage interest, state and local taxes and charitable gifts, add up to more than these amounts.

Does the UK calculation apply in Scotland?

No. The UK figures use the England, Wales and Northern Ireland bands for 2026/27: a £12,570 personal allowance, 20% basic rate on the next £37,700, 40% higher rate and 45% additional rate. Scotland sets its own bands and rates on non-savings income, with more bands, so Scottish taxpayers will see different income tax figures. National Insurance, shown in the Paycheck Calculator, is UK-wide and does apply in Scotland.

What is the difference between marginal and effective tax rate?

The marginal rate is the rate on your last unit of income — the highest bracket you reach. The effective rate is total tax divided by gross income. A single US filer on $85,000 in 2026 is in the 22% bracket, but pays $9,870 in total, an effective rate of 11.6%, because the first $16,100 is untaxed and the next slices are taxed at 10% and 12%. The effective rate is almost always lower than the marginal rate.

What does the calculator leave out?

It is an estimate for a single resident employee. It ignores itemized deductions, tax credits and offsets not listed in the formula (for example Australia's Low Income Tax Offset), Scottish rates, US local taxes and Japanese per-capita resident levies. State and provincial tax use the flat rate you enter.
