Effective tax rate calculator
Compute a simple effective business tax rate from your own profit and tax figures and benchmark it against the headline corporate rate.
Methodology
Effective rate = (tax paid + optional dividend tax) ÷ profit before tax. It is benchmarked only against the country's headline corporate income tax rate. The real effective tax rate depends on accounting treatment, deductions, loss carry-forward, local/municipal taxes, withholding, and treaties — none of which are modelled here. This is descriptive arithmetic on your own figures, not legal or tax advice and not a claim of tax optimisation.
Country data last updated .
These calculations are informational estimates based on headline rates and transparent assumptions — not tax, accounting, or legal advice. Verify with a qualified local advisor before relying on the results.
Data limitations
- Corporate tax figures apply the headline statutory rate only — they exclude deductions, loss carry-forward, incentives, local surtaxes, and effective-rate timing.
- Estimates use headline rates; your effective rate depends on deductions, incentives, timing, and local taxes specific to your business.
