This calculator turns an hourly wage into a gross annual salary, then estimates your District of Columbia take-home pay after FICA, federal income tax, and the District’s graduated income tax. The District does not add a separate local wage tax on top of its income tax.
How it works
Gross salary is the hourly rate times hours per week times weeks per year, and take-home is what remains after the withholdings:
gross = hourly × hours/week × weeks/year
FICA = 6.2% Social Security (to wage base) + 1.45% Medicare
fed tax = federal brackets on (gross − federal standard deduction)
DC tax = DC graduated brackets on (gross − DC standard deduction)
net = gross − FICA − fed tax − DC tax
The District of Columbia standard deduction matches the federal amount, and the District schedule runs from 4 percent up to 10.75 percent.
Example and notes
At 30 dollars an hour, full time, gross salary is 30 × 40 × 52 = 62,400
dollars. FICA, federal income tax, and District of Columbia income tax are then
subtracted to find net pay, which is divided by 26 for a bi-weekly figure. This
is an estimate that excludes 401(k), pre-tax benefits, the additional Medicare
surtax, and credits. Confirm specifics with a tax professional and the DC Office
of Tax and Revenue.
