Worked example: $85,000 of 1099 income in Iowa
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 $2,926 to Iowa — about 27.2% of your profit in total. That leaves $56,079 a year, or $4,673 a month.
That state tax works out to an effective 3.8% of your profit, which is the number to add to your federal set-aside when you plan cash flow in IA.
