What to do next
How it works
Profit is your 1099 income minus expenses. Self-employment tax is 15.3% of 92.35% of that profit. Half of it, the standard deduction and the 20% qualified business income deduction come off before federal income tax. Idaho tax is estimated from the same income using a flat 5.3% state income tax.
Things to keep in mind
No tax is withheld from 1099 payments, so the total here is what you need to set aside and pay in quarterly installments. The quarterly estimated tax calculator turns it into four payments.
Health insurance premiums, SEP-IRA or solo 401(k) contributions and a home office can cut the bill well below this estimate.
