What is the effective corporate tax rate?
The effective tax rate is the actual average rate a company pays on its pre-tax income, as opposed to the statutory (legally listed) tax rate. It reflects deductions, credits, and tax planning strategies actually used.
The formula
Effective Tax Rate = (Total Tax Expense / Pre-Tax Income) × 100. Comparing this figure to the statutory rate shows how much a company’s actual tax burden differs from the headline rate.
