Understanding Effective Tax Rates
Definition
Effective Tax Rate is the actual percentage of a corporation's income that is paid in taxes. Unlike the statutory rate (the official rate set by law), the effective rate reflects the real tax burden after all deductions, credits, and other tax provisions are considered.
Calculation Method
The effective tax rate is calculated by dividing total tax expense by taxable income:
This gives the actual tax rate as a decimal, which is typically converted to a percentage by multiplying by 100.
Important Rules
- Federal Rate: 21% for corporations as of 2018
- State Taxes: Additional state corporate taxes may apply
- Effective Rate: Actual rate may differ due to deductions and credits
