How do I pay income and self employment tax on a new 1099 contractor position?
More specifically, my spouse and I both work full time for employers and are paid on a W2. In addition, there will be a 1099 for a second job as a consultant (started 1/10/20). I know that the 1st qtr estimated taxes are due. I know income tax is tax bracket based on total income. But do I add the estimated gross or net to our previous year AGI to have an idea of total income? For the self-employment tax, on the 1040SE do I just use the income from the 1099 position? I believe this is figured as (estimated gross 1099 income- deductions) x 0.50 = estimated annual tax. Take that number /4 for qtrly pmt amount. Can anyone tell me if I am on the right track at all?
For ease of numbers, lets say our combined annual w2 income is 80k (22% income tax bracket). 1099 shows 20k. expenses for contractor job is 2k.
I would need to hold back 22% of the 18k for income tax. ($3960) divide by 4 to get qrtly amount $990
For self employment tax: 20k-2k= 18k 12.4% of 18k ($2232) for Social Security, 2.9% of 18k ($522) for Medicare. Total self emp tax = $2754.00 Half deductible as employer portion. So SE tax owed is $1377. Divide by 4 to get quarterly SE tax payment amount of $344.25
Total to send as est tax qtr payment is $1334.25
Does this look right, sound right??? Am I completely off base?? lol
