Single

Taxable Income (Form 1040 Line 15)	Tax Rate in 2020
$0$9,875	10%
$9,876$40,125	$988 plus 12% of the amount over $9,875
$40,126$85,525	$4,617 plus 22% of the amount over $40,125
$85,526$163,300	$14,605 plus 24% of the amount over $85,525
$163,301$207,350	$33,271 plus 32% of the amount over $163,300
$207,351$518,400	$47,367 plus 35% of the amount over $207,350
$518,401 or more	$156,234 plus 37% of the amount over $518,400

$4,617 + (0.22 x (75,000-40,125)) = $4,617 + (0.22 x $34,875) = $4,617 + $7,672.50 = $12,289.50 Total Tax
