Official sources and assumptions
Rules checked:
United States
Personal income tax: US federal ordinary income, adult under 65, not a dependent. Enter income before the selected standard deduction. No state tax, payroll tax, AMT, special deductions or credits.
Company income tax: US federal C corporation, 21%. Not an LLC/pass-through calculation. Excludes state taxes, credits, losses and corporate alternative minimum tax.
United Kingdom
Personal income tax: England, Wales and Northern Ireland only, 6 Apr 2026–5 Apr 2027. Enter ordinary income equal to adjusted net income, before Personal Allowance. No savings, dividends, National Insurance or other allowances.
Company income tax: Ordinary UK-resident standalone company, full 12 months. Assumes no associated companies or exempt distributions; augmented profit equals taxable profit. Includes 19%/25% rates and marginal relief. Not for close investment-holding or ring-fence companies.
Germany
Personal income tax: Enter taxable income (zu versteuerndes Einkommen), not gross salary. 2026 basic single-person tariff; allowance already built in. No splitting, solidarity surcharge, church tax or social insurance.
Company income tax: 2026: 15% corporate tax plus 5.5% of that tax as solidarity surcharge. Trade tax uses your multiplier and the same adjusted profit, rounded down to €100; actual trade-tax adjustments may differ.
Australia
Personal income tax: Full-year resident, 1 Jul 2026–30 Jun 2027. Enter taxable income; full adult tax-free threshold. Before all offsets, including LITO, Medicare levies and student-loan repayments.
Company income tax: 30% standard rate. Choose 25% only if aggregated turnover is below A$50m and base-rate passive income is no more than 80% of assessable income. Eligibility is not determined here.
Singapore
Personal income tax: YA 2026 assesses 2025 income. Enter resident chargeable income after deductions and reliefs. Before any rebates; excludes CPF. The temporary YA 2025 rebate is not applied.
Company income tax: 17% baseline before partial/start-up exemptions, YA 2026 rebates, cash grants and other relief. This can substantially exceed final payable tax. Use the IRAS source to assess applicable reductions.
United Arab Emirates
Personal income tax: Wages/salary only. No UAE personal income tax. Business corporate tax, VAT, pension contributions and obligations in other countries may still apply.
Company income tax: Ordinary mainland/non-qualifying-free-zone company: 0% to AED375,000, 9% above. Before Small Business Relief, credits and losses. Excludes qualifying-free-zone regimes, special sectors and minimum top-up tax.
Questions about this tax calculator
Which taxes and countries are supported?
Switch between personal income tax, ordinary company income tax and VAT/GST/sales-tax arithmetic for the US, UK, Germany, Australia, Singapore and UAE. Each mode has its own scope and assumptions; this is not every tax in every country.
Can I use this for a cross-border tax return?
No. The tool calculates a bounded domestic scenario in local currency. It does not establish residency, permanent establishment, treaty rights, sales-tax obligations or the final amount you owe.
Is the calculator free and private?
Yes. No account or payment is needed. Your entered amounts are calculated locally and are not sent to a tax API. Review the dated official sources before relying on an estimate.
