Notes:

These are the $2020$ tax rates that will be paid on tax returns due April $15,2021.$ The income ranges at

which each tax rate takes effect are indexed with inflation, so they change each year.

The average tax rates are always below the marginal rates, but in $2020$ the average at the top of the

brackets approaches $37\%$ as taxable income rises without limit$.$

In $2018,$ the personal exemption for the taxpayer and dependents was eliminated. With the deduction

limitation on state and local property, income, and sales taxes and the existence of payroll taxes $($Social

Security and Medicare taxes$),$ the $2020$ effective tax rate will be higher than $37\%.$
