Effective Corporate Tax Rate Calculator
Enter the company's pre-tax income (EBT), income tax expense (from the income statement), and the relevant statutory rate to calculate the effective tax rate and compare it with what the firm would have paid at the headline rate.

How does this calculator work?
ETR = Tax Expense / Pre-tax Income × 100. It measures the real tax burden versus the stated statutory rate. An ETR below the statutory rate reflects credits, deductions or lower-taxed foreign income; above it reflects non-deductible costs or uncertain tax positions. The US federal statutory rate is 21% from 2018.
Formula
How this is calculated
The effective corporate tax rate (ETR) is the ratio of the total income tax expense reported on the income statement to the pre-tax income (earnings before tax, EBT): ETR = Tax Expense / EBT × 100. It captures the actual tax burden as a percentage of earnings, unlike the statutory rate which is the legislated headline rate applied to taxable income.
The two rates differ because companies may benefit from tax credits, tax-loss carryforwards, R&D deductions, accelerated depreciation, preferential rates on foreign income, or deferred tax liabilities. An ETR below the statutory rate suggests the company is benefiting from such provisions; an ETR above it may indicate non-deductible expenses, penalties, or uncertain tax positions creating additional charges. The tax expense shown on the income statement combines the current-year tax payable plus or minus the change in deferred tax assets and liabilities.
As a reference point, the US federal statutory corporate rate is 21% from 2018 onwards (set by the Tax Cuts and Jobs Act); state taxes add a further 4–10% on average, pushing the combined rate to roughly 25–29%. ETRs in practice range widely — many large multinationals report effective rates of 10–18% through global tax planning. The statutory rate entered in this calculator is an editable estimate for comparison; always verify the rate applicable to your specific jurisdiction and year.
Frequently asked questions
Many factors reduce the ETR below the statutory rate: tax credits (R&D, investment, energy credits), lower-taxed foreign income, stock-option deductions, tax-loss carryforwards from prior years, percentage-depletion allowances for extractive industries, and deferral strategies. Large multinationals with global operations and transfer-pricing arrangements often achieve ETRs well below their home-country statutory rate.
Current tax is the amount actually payable to tax authorities for the period, calculated on taxable income using the statutory rate. Deferred tax arises from temporary differences between accounting income and taxable income — for example, accelerated depreciation creates a deferred tax liability (tax payable in future years). The income tax expense in the income statement is the sum of current and deferred tax components.
Yes — if a company reports positive pre-tax income but receives a net tax benefit (e.g. from releasing a large deferred tax asset or claiming refundable tax credits), the income tax expense is negative and so is the ETR. It can also result from reversing prior-year provisions. Negative ETRs are disclosed and explained in the tax note of annual reports.
