By the time you file, the decision's made. See the tax first.
Weighing a sale, an option exercise, a big contribution, a move to a new state? Get a forward projection of your federal and state tax with your options modeled side by side — so you see the cost of each path before you commit, not in a surprise bill next April. Just the numbers, so you can decide.
Just $29. A professional tax projection runs $500–$1,500.
Timing and bracket changes move the number. The projection runs your real scenario — this is illustrative.
The most useful tax math happens before you act — but almost nobody runs it then.
A raise, a sale, an exercise, a move — each one has a tax consequence that's far easier to plan around before it happens. This puts that number in front of you while you still have choices.
The same decision can cost very different amounts of tax.
Sell now or in January. Exercise all at once or in tranches. Take the bonus this year or defer it. Contribute pre-tax or Roth. Each version lands in a different spot on your bracket, changes what phase-outs and credits you keep, and can trigger — or avoid — an estimated-tax shortfall.
A projection puts those versions next to each other so the trade-off is a number you can see, not a gut call you second-guess later.
Illustrative. Your scenarios are computed from the income and decisions you enter.
Getting the tax math up front usually means paying up front.
$500–$1,500 for a one-off forward projection — thorough, but a booking, a wait, and a bill every time a new decision comes up.
Many are heads-down until filing, and a quick "what would this do?" often can’t get the modeling it needs outside of season.
Fine for a single rough number, but it won’t compare timings, model your state, or handle a specific decision the way a projection does.
Free, until an unplanned move lands you in a higher bracket or triggers an 8% underpayment charge you didn’t see coming.
Seeing a decision's tax cost before you make it shouldn't cost more than the decision.
Enter your year and your options. We project. You choose.
Your projected federal and state tax for the year on your current trajectory — the number every scenario is measured against.
The specific moves you’re weighing, each modeled and projected so you can compare the tax head to head.
Which bracket your next dollar — and your next decision — lands in, and how close you are to the edges.
This year vs. next, all-at-once vs. staged — see how timing alone moves the total.
Whether you’re on track to have paid enough, so an underpayment charge isn’t a surprise.
A written side-by-side you can save and take to your tax professional before you act.
Projection and estimates only — not tax advice, and it does not file or pay anything. Compare the scenarios and confirm with a licensed tax professional before you act.

How it works
Your income (actual and projected), the decisions you’re weighing, your filing status, and your state.
A baseline plus 3–5 custom what-ifs, each run through federal and state calculations.
A side-by-side you can download and take to your preparer — before you commit.
Takes minutes. No commitment. Re-run it as your plans change.
You don't have to be caught off guard by your own tax bill.
The stressful part of a big financial move usually isn't the move — it's not knowing what it'll cost until it's done. That surprise is avoidable. Running the numbers ahead of time turns a nervous guess into a clear-eyed choice, and it takes minutes. No pressure to do anything with it — just the peace of mind of seeing the number first.
A professional forward tax projection runs $500–$1,500. No subscription.
Frequently asked questions
- Is this tax advice?
- No. It is an educational modeling tool that projects your federal and state tax under scenarios you choose. It does not tell you what to do or file anything — it lays the numbers side by side so you can decide, ideally with a licensed tax professional.
- How is this different from the Free Tax Modeler?
- The Free Tax Modeler is a live, interactive model you drive yourself. This projection is a structured, forward-looking analysis of specific decisions you are weighing — with 3–5 custom what-if scenarios, marginal-rate and timing analysis, and a written comparison you can keep and share.
- Can it help me avoid an underpayment penalty?
- It can show you your projected liability so you can see whether your withholding or estimated payments are on track. It does not file or pay anything for you, and it can’t guarantee you avoid a penalty — that depends on what you actually pay and when.
- What do I need to get started?
- Your current-year income (actual and projected), the decisions you’re weighing (a sale, an exercise, a large contribution, a move), your filing status, and your state of residence. The more specific the scenario, the sharper the projection.
- Do you sell my data?
- No. The figures you enter are used to build your projection. See our Privacy Policy for details.
