How the math works
Every figure comes from the IRS and Social Security Administration numbers for tax year 2026.
Refund estimator
- Standard deduction: $16,100 single, $32,200 married filing jointly, $24,150 head of household.
- 2026 brackets from 10% to 37%, applied one slice at a time.
- Child tax credit of $2,200 per child under 17, with up to $1,700 per child refundable.
- For filers 65 and older, the extra standard deduction plus the $6,000 senior deduction, which phases out above $75,000 of income ($150,000 joint).
LLC taxes
- Net profit = revenue minus business expenses. A one-owner LLC is taxed like a sole proprietor unless it elects otherwise.
- Self-employment tax: 15.3% on 92.35% of profit. Your W-2 wages use up the $184,500 Social Security cap first.
- Income tax: the extra federal tax the profit adds on top of your other wages, after deducting half the self-employment tax and the 20% QBI deduction.
- Quarterly payment: the total divided by four, as a starting point for estimated taxes.
S-corp savings
- Sole proprietor: 15.3% self-employment tax on 92.35% of profit, with the 12.4% Social Security part capped at $184,500.
- S-corp: the same 15.3% payroll tax, but only on the salary you pay yourself.
- Savings = self-employment tax minus payroll tax minus the extra cost of running the S-corp.
What they leave out
Itemized deductions, capital gains, the earned income credit, QBI limits for higher incomes and certain professions, the 0.9% additional Medicare tax, Indiana's 2.95% state tax and county tax, and anything unusual about your year. They're a starting point for a conversation, not a return.
