As a W-2 employee on the same pay
An employee's payroll tax is split with their employer, so the same gross pay keeps more. The gap is roughly the premium you should build into your contractor rate (before benefits).
Both estimates include Missouri state income tax before state-specific deductions and credits.

Worked example: $85,000 of 1099 income in Missouri
Say you invoice $85,000 over the year and claim $8,000 of business expenses, leaving $77,000 of net profit. You would owe roughly $7,115 in federal income tax, $10,880 in self-employment tax and $3,443 to Missouri — about 27.8% of your profit in total. That leaves $55,562 a year, or $4,630 a month.
That state tax works out to an effective 4.47% of your profit, which is the number to add to your federal set-aside when you plan cash flow in MO.

The IRS expects self-employed workers to pay as they earn, in four instalments. On the worked example above, each payment would be about $5,360. Missing a deadline triggers an underpayment penalty even if you pay in full when you file.
