there is only one scenario. you simply add the short term gain to your wages. You never stated whether you are single or married, but I will assume marreid
1) your wages are $100,000 and add to that the hypothical the $218,000 profit = $318,000 of adjusted gross income.
2) Then subtract the standard deducton of $25,900 leaves taxable income of $292,100.
3)if you look below, adding $218,000 means some of it is taxed at 12%, some at 22% and the rest at 24%
(Single) (Married Filing Jointly) 10% | Up to $10,275 | Up to $20,550 |
12% | $10,276 to $41,775 | $20,551 to $83,550 |
22% | $41,776 to $89,075 | $83,551 to $178,150 |
24% | $89,076 to $170,050 | $178,151 to $340,100 |
32% | $170,051 to $215,950 | $340,101 to $431,900 |
35% | $215,951 to $539,900 | $431,901 to $647,850 |
37% | Over $539,900 | Over $647,850 |
