This calculator estimates 2026 federal self-employment tax, federal income tax, and state income tax on net 1099/Schedule C profit. State tax uses single-filer brackets regardless of the filing status selected above, and approximates each state's taxable income as profit minus the federal standard deduction rather than that state's own deductions — so the state figure is directional, not a liability estimate, especially for married filers and states with different deduction rules (e.g. Pennsylvania, which has no standard deduction). It also does not model the QBI deduction (which would lower income tax for many filers), tax credits, or state estimated-payment rules. Consult a tax professional for personalized advice.
2026 federal tables from IRS Rev. Proc. 2025-32; Mississippi rates from the state's revenue department and statutes (2026 rates; brackets, standard deduction and exemptions from the latest published state tables, 2025 where the state has not released 2026 figures); quarterly due dates and the underpayment safe harbor from irs.gov.

Mississippi self-employment tax questions.
About 30% of net profit, based on a single filer with no other income. $75,000 of 1099 profit works out to roughly $19,158 a year — $4,789 a quarter — in self-employment tax, federal income tax, and state income tax.
15.3% of 92.35% of your net self-employment income: 12.4% for Social Security (up to the annual wage base) and 2.9% for Medicare (no cap), plus an additional 0.9% Medicare surtax above $200,000 (single or head of household), $250,000 (married filing jointly), or $125,000 (married filing separately). This applies in every state, including Mississippi — it is a federal tax.
Four payments: April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027, per the IRS estimated-tax schedule — pay each one in full as it comes due. If you started earning partway through 2026, the quarters before your income started can still trigger an underpayment penalty, but Form 2210's annualized income installment method (Schedule AI) can reduce or eliminate it for income received unevenly across the year.
Yes. Mississippi taxes income after deductions under its progressive income tax (0% to 4%) — this estimate subtracts the federal standard deduction and half of self-employment tax before applying Mississippi's single-filer brackets, regardless of filing status — in addition to federal self-employment and income tax.
Estimates use 2026 federal and state tax rates on net profit after business expenses. State tax always uses single-filer brackets and approximates the state taxable-income base as profit minus the federal standard deduction, rather than modeling each state's own deductions and filing-status-specific brackets — so the state figure is directional, not a liability estimate, especially for married filers or states whose rules differ from the federal standard deduction (e.g. Pennsylvania, which has none). It also does not model the QBI deduction (which would lower income tax for many filers), tax credits, retirement contributions, or state-specific estimated-payment rules.
