Year-round tax checkup · An employer-sponsored benefit
Don't let April surprise you.
Tillee watches your paycheck, withholding, and W-4 all year — and tells you in plain English whether you're headed for a refund or a bill, while there's still time to change it.

From our conversations and surveys with US employees and HR teams.
TurboTax tells you what happened. Tillee helps you change what will happen.
Tax software looks backward — it files last year. Your W-4 quietly decides this year, and most of us filled it out once, guessed, and never looked again. By the time you find out it was wrong, the only thing left to do is pay.
How it works
1 · Connect.
Tillee links to your payroll and builds your tax picture automatically — you only fill the true gaps, like a spouse's income or a move.
2 · See where you're headed.
One clear answer, updated all year: refund or bill, how big, and what's driving it. Every estimate shows its confidence — Tillee says what it doesn't know instead of guessing.
3 · Act before it's too late.
Try out a raise, a marriage, a second job in the sandbox. When a change makes sense, Tillee generates your updated W-4.

Your employer can't see any of it.
Tillee comes to you through work, but what you do inside it is yours alone. Your employer never sees your questions, your numbers, or whether you've even logged in. That's a promise built into the product, not a settings toggle.

Questions people ask
Is Tillee tax advice?
No. Tillee is decision support: it shows you where you're headed and what your options are. For advice on your specific situation, Tillee connects you to qualified professionals.
Can my employer or HR see what I do in Tillee?
Never. Not your questions, not your numbers, not your activity.
What does it cost me?
Nothing. Tillee is a benefit your employer provides, like an EAP or a 401(k) match.
How do I get access?
Through your employer. If they don't offer Tillee yet, point them to our For HR teams page.
How accurate are the projections?
Tillee runs a deterministic tax engine on your real payroll data — not a chatbot guessing. Every estimate shows a confidence level based on how complete your picture is.
