I'm an entrepreneur with a software and data science background. When I hit a problem, I build the solution. That's just how I'm wired. I find something broken or missing in my own life, figure out the fix, and then realize others probably need it too. That's where all my tools come from — real problems I actually had.
Report
The LLC vs S-Corp comparison actually broke down the payroll tax savings in a way I could follow, which is rare for these tools. The missed deduction check also flagged a home office write-off I had completely overlooked last year.

would love to see state tax breakdown in there too, honestly federal is great but knowing the state impact on each deduction would make the savings estimate way more useful

The instant breakdown of LLC vs S-Corp savings right next to the 401k/IRA/HSA sliders is honestly super smart, makes it way less overwhelming to actually compare scenarios side by side.
