Free AI calculators that tell you exactly what you owe — S-Corp savings, QBI deductions, state-by-state comparison. Built for indie hackers and founders who'd rather ship products than pay extra taxes.
The IRS doesn't send you a bill with suggestions. These tools do the math so you can make real decisions — not guesses.
At $80K+ net income, an S-Corp typically saves $5,000–$12,000/year in self-employment tax. This calculator tells you your exact breakeven, your projected savings, payroll cost offset, and whether the timing makes sense for your situation.
Self-employment tax is 15.3% on top of income tax — and most founders underestimate it. This tool breaks down your exact SE tax bill by SS + Medicare components, the 50% deduction you get back, and your effective rate after deductions.
Stop guessing which structure makes sense. Enter your revenue and the tool outputs a full comparison of after-tax income across Sole Prop, LLC, S-Corp, and C-Corp — at your income level, in your state, with your filing status.
State income tax is only one piece. This tool stacks income tax, capital gains rates, sales tax, and property tax across all 50 states into a single side-by-side comparison — so you can see the full picture before you move your LLC.
"Freelancers deserve the same tax intelligence as Fortune 500 companies."
Big companies pay accountants six figures to optimize their tax structure. Indie hackers pay $15/hr for a rushed H&R Block appointment — and leave the table with the same generic advice everyone gets. We built TaxStackHub because that gap is structural, not inevitable.
The math isn't actually complicated. S-Corp elections, QBI deductions, state comparisons — these are solved problems. We just made the solutions free, instant, and specific to your actual numbers. No upsells, no intake forms, no appointment required.
