The District of Columbia taxes the taxable income of every resident on a graduated scale for taxable years beginning after December 31, 2021 (D.C. Code § 47-1806.03(a)(11)): 4% on taxable income up to $10,000; 6% from $10,001 to $40,000; 6.5% from $40,001 to $60,000; 8.5% from $60,001 to $250,000; 9.25% from $250,001 to $500,000; 9.75% from $500,001 to $1,000,000; and 10.75% on income over $1,000,000. Instead of computing the tax by formula, you may use the tax table the Mayor prescribes, which must match these rates.
“Over $500,000 but not over $1,000,000 $42,775, plus 9.75% of the excess over $500,000 Over $1,000,000 $91,525, plus 10.75% of the excess over $1,000,000”
