Jackson Hewitt tax calculator vs our AI estimator

What Jackson Hewitt is, and what this is

Jackson Hewitt prepares returns through offices, including seasonal locations inside retail stores, and its free tools sit at the top of that funnel. What it competes on is proximity and speed at the moment a refund is wanted — which is a different proposition from software and should be evaluated as one.

The products that follow the estimate are where the real decisions are: assisted preparation, and commonly an advance against the refund. Both can be reasonable choices. Both are much easier to judge when you already know roughly what the refund is going to be, which is the one thing the free tool is there to tell you and the one thing worth checking somewhere with nothing riding on the answer.

This site sells nothing. There is no filing product to upsell, no adviser network, no deposit account, and no account to create — which is worth stating plainly because it is the structural difference between the two, and structure predicts behaviour better than intentions do.

What it is instead: a deterministic calculator over verified rate data. On $85,000 single it puts federal income tax at $9,870 and FICA at $6,503, then adds your state and, where one exists, your city. The arithmetic is fixed; the language model on these pages explains a number it was given and never computes one.

What goes into each calculation

We have not audited Jackson Hewitt's calculator ourselves, and we are not going to describe what it does from memory. Everywhere else on this site we distinguish between "we checked" and "we have not looked", and a comparison page is exactly the wrong place to stop doing that.

What can be said without checking is structural. Jackson Hewitt is in the business of preparing returns; its calculator is free because preparation is not. Whatever its scope, that is the relationship, and it is different from a calculator that has nothing to sell you afterwards.

What this one covers is on the record: federal brackets and FICA from the IRS revenue procedure, every state's own rates read off its department of revenue, and 3,672 local jurisdictions across 7 states. Open both and compare the line items — that comparison is worth more than anything either of us writes about the other.

The property side is the other difference, and nothing in this category joins it up. The tax on a salary and the tax on a house are what actually decide whether a move works, they are set by different authorities, and comparing either alone regularly produces the opposite of the right answer. Every one of the 3,143 US counties has a page here.

The same salary, run here

Take $85,000, single, standard deduction. Federal income tax is $9,870 — an effective 11.61% against a marginal bracket of 22.00%, which is the gap that makes people think their calculator is broken. FICA adds $6,503, flat from the first dollar with no deduction at all.

That much is the same wherever you run it, because federal tax does not care where you live. What changes the answer is the next line: state tax on the same salary runs from $0 to $6,604, and then local tax on top in eleven states.

Both tools reach that line, so the comparison here is not about scope. It is about whether the rate applied is the current one, which is the section above, and about what you are shown alongside the answer.

Run the same figures in both and compare the line items rather than the total. If the totals differ, the useful question is which line differs and why — a different standard deduction means one of the two is using last year's, and a missing state or local line means one is answering a different question.

Refund advances, and why the estimate matters before you sign one

Storefront preparers commonly offer an advance against your expected refund — money now, repaid automatically when the refund arrives. They are widely marketed as free or as no-interest, and for the customer they often genuinely are, because the cost sits in the preparation fee rather than in a stated rate.

Understand what is being advanced. A refund is not a payment from the government; it is your own over-withheld money coming back, without interest, after being held for up to sixteen months. An advance is therefore a short-term loan against money that was already yours, and the reason it feels valuable is the delay, not the amount.

Which makes the estimate the important step, and the one to take before signing anything. If the advance is sized against a refund that does not materialise — because a second job was under-withheld, because FICA was counted as withheld income tax, or because a credit was assumed that phases out at your income — the shortfall is still owed.

The structural fix is upstream and costs nothing. A refund that arrives every year in the thousands is a withholding setting, not a windfall: Step 4(c) of the W-4 moves the money into your monthly pay instead, and someone who does that has no reason to borrow against a refund at all because there is not much of one left to borrow against.

None of that is an argument against using a preparer, and for a complicated return it is money well spent. It is an argument for knowing the number first — because an advance sized against a guess is the one product in this category where being wrong has a direct cost.

The part nobody checks: whether the numbers are current

Every calculator in this category applies the same arithmetic. What separates them is whether the rates going in are this year's, and that is checked far less often than you would expect — including by tools that are otherwise carefully built.

When we audited the category in August 2026 we found sites ranking on the first page for "income tax calculator 2026" that were serving the previous year's figures: a standard deduction of $15,200 single instead of $16,100, and a first bracket ending at $11,925 instead of $12,400. Several linked to the correct IRS page from the same screen.

State data goes stale faster still, because states legislate on their own calendars and backdate. Of the 37 states we checked against their own department of revenue, 12 carried a wrong rate, threshold or credit in the compiled sources everyone uses. Ohio's bill was overstated by 43% because a source treated a flat rate as flat from the first dollar. Georgia cut its rate in May with effect from 1 January, so a table published in April was correct when written and wrong by summer.

So every figure here carries the document it came from and the date it was verified, and the log is published rather than kept internally. Where a state has not yet been read off a primary source, the page says so instead of implying it has — "we have not looked" and "it does not exist" are different claims, and treating them as the same is how a calculator confidently tells someone a relief they qualify for is not available.

This is the one comparison we would ask you to actually run. Take any tool, including this one, find the standard deduction it is using, and check it against the IRS revenue procedure. It takes two minutes and it tells you more about a calculator than any feature list.

If two calculators disagree, here is how to find out which is wrong

Work down the lines rather than arguing about the total. Almost every discrepancy in this category comes from one of five places, and each has a tell you can check in under a minute.

The standard deduction. Find the figure each tool used. For 2026 it is $16,100 single and $32,200 joint. If one is using $15,200 or $30,400, it is serving last year's numbers, and everything downstream of that is wrong by the difference times your marginal rate.

Whether FICA is included. A tool showing federal income tax of $9,870 on $85,000 and a tool showing $16,373 are not disagreeing — one is reporting income tax and the other total federal tax. Both are correct about different things, and the labels are frequently ambiguous.

Whether state tax is in there at all. This is the largest single cause of a big gap, because a federal-only tool is simply answering a narrower question. Check whether the tool ever asked you what state you live in; if it did not, it cannot have included it.

Gross versus net input. Some tools ask for gross pay and some for taxable wages after pre-tax deductions. Feeding a gross figure into a field expecting net, or the reverse, moves the answer by the size of your 401(k) and health premiums — which is thousands, not rounding.

Marginal versus effective rate. A tool reporting 22.00% and one reporting 11.61% on the same salary are both right: the first is the rate on your next dollar, the second the average across everything you earned. Comparing one against the other is the commonest reason people conclude a calculator is broken when it is not.

If all five line up and the totals still differ, one of the two has a stale state rate — and that is the case where checking against the state's own department of revenue publication is the only way to settle it.

Where Jackson Hewitt is the better choice

Availability is a real advantage and an underrated one. Walk-in offices, extended hours in season and locations inside stores you were going to visit anyway solve a problem that no website solves: getting the thing done rather than intending to.

For a filer who wants the return finished in one sitting, with someone else responsible for it, that convenience is worth paying for — and it is a category of value a calculator cannot supply at any price.

And if you are going to have the return prepared in person, the estimate beforehand is orientation only. Where you run it barely matters; what matters is that you ran one before agreeing to anything priced against the refund.

What each one does with what you type

Tax figures are among the more revealing things a person enters into a web form: salary, marital status, dependants, where you live, sometimes what you own. It is worth knowing where they go before you type them.

A free estimator attached to a paid product is, among other things, a lead capture. That is the normal arrangement and it is not hidden — but it means the natural end of the flow is an account, an email address, or a prompt to continue into the paid product, and the figures you entered are how the offer that follows gets targeted. Read whatever privacy terms apply to the free tool specifically; they are not always the same as the ones covering the paid product.

This site asks for no account, no email and no name. The calculation runs in your browser, the figures are not stored against an identity, and there is no product to route you into afterwards. That is not a virtue so much as a consequence of the business model: there is nothing here that a profile of you would make more valuable.

The AI explanation is the one place data leaves the browser, and it is worth being precise about it. What gets sent is the computed figures — income, tax amounts, rates, state — so the model can describe them in plain English. It is not sent a name, an email or anything identifying, and it never computes a number: the arithmetic is settled before the model sees anything, which is the only arrangement in which a language model belongs near a tax figure.

Which one for which question

Wanting it finished today, in person, by someone who takes responsibility for it: Jackson Hewitt or another walk-in preparer. That is a service, and no calculator is competing with it.

Comparing two job offers in two states, or two cities: here. That is the question this was built for, and it needs the state and local lines that a federal-only tool does not compute.

Setting or fixing your W-4: neither, strictly. The IRS Tax Withholding Estimator is the authoritative tool for that specific job, it is free, and its output maps onto the form's numbered steps. We say so on its own comparison page too.

Deciding whether a move is worth it: this, but using both halves. Income tax on one side and county property tax on the other, because states trade the two against each other and every comparison built on one alone is unreliable in a predictable direction.

Checking whether a number you were given is plausible: any of them, twice. Two independent tools agreeing is weak evidence and two disagreeing is strong evidence that one of them is out of date — which is worth finding out before you make a decision on it.

What this page does not claim

We have no affiliation with Jackson Hewitt, no partnership, and no relationship of any kind. We do not use their logo or their branding, and nothing here should be read as their statement or as endorsed by them. Jackson Hewitt is their name, used to identify what is being compared, which is what a comparison requires.

We have not audited their tool, and this page says so above rather than describing it from general impression. If we audit it, this page will say what we found and when.

We are not making claims about their accuracy. We did not find errors in Jackson Hewitt's figures and we are not implying any — the data section above describes what we found across the category and names the specific pattern, which is stale figures on sites that publish no verification date at all.

And we are not a filing service, a tax adviser or a substitute for one. This is a planning calculator. Where a situation needs professional judgement, it needs a professional, and several of the products compared on this page supply one.

Questions

Is this a good alternative to Jackson Hewitt?

For working out what a salary is worth in a particular state and city, yes — it computes federal, FICA, state and local income tax together and it is free with no account. For filing a return it is not an alternative to anything: it does not file. And Jackson Hewitt answers a narrower question, which is fine when that is your question.

Is it free? What is the catch?

Free, no account, nothing stored. There is no filing product to sell you, no adviser network and no deposit account. The site is funded by advertising and by a paid API for businesses, neither of which changes the number you are shown — which is the only guarantee that matters here.

Which is more accurate?

Accuracy in this category is almost never about the arithmetic — everyone applies the same brackets correctly. It is about whether the rates going in are current. Of 37 states we checked against their own department of revenue, 12 carried a wrong figure in the compiled sources. Every number here shows the document it came from and the date it was checked, so you can verify rather than trust.

Does it include state and city taxes?

Yes. All 51 jurisdictions for state income tax, each read off the state's own publication, plus 3,672 local jurisdictions across 7 states — every Pennsylvania municipality, every Ohio municipality and school district, all 92 Indiana counties, Maryland's counties, Michigan's cities and New York City. Local income tax is the layer most national calculators omit entirely.

What does it calculate on $85,000?

Federal income tax of $9,870 and FICA of $6,503 for a single filer taking the standard deduction, then your state's own tax and any local tax on top. It shows two effective rates — one on income tax alone, which compares to your marginal bracket, and one including FICA, which is what actually leaves your pay.

Are you affiliated with Jackson Hewitt?

No. No affiliation, no partnership, no sponsorship. We do not use their logo or branding. Their name appears here to identify what is being compared, and the page includes a section on where their product is the better choice — because a comparison that finds its own side better at everything is not a comparison.
