State Filing Fees: The Tax Software Cost People Miss

The headline price you see advertised is almost always federal only — state filing is a separate line item on nearly every product.

Nearly every piece of marketing for tax software leads with a federal filing price, and it's easy to assume that's the whole cost. It usually isn't. Federal and state returns run on different tax codes and different forms, so software providers price them separately — a pattern consistent enough across TurboTax, H&R Block, TaxAct and most competitors that it's worth treating as the default assumption rather than the exception.

Why this happens

Each state that collects income tax has its own set of forms and rules, and software companies build and maintain separate modules for each state. That development cost gets passed on as a separate fee, layered on top of whatever federal tier you're using. If you live in a state with no income tax — currently a short list including Texas, Florida, and a handful of others — this entire cost doesn't apply to you. Everyone else should expect it.

What it typically costs

State filing fees vary by provider and by year, but as a general pattern: free federal tiers that also offer free state filing are less common than free federal alone. Paid tiers usually add a separate state filing charge on top of the federal price, and if you need to file in more than one state — because you moved, or worked remotely for an employer in a different state — expect to pay the state fee again for each state.

How to actually compare total cost

When comparing two products, the only fair comparison is federal plus state plus any add-ons you'll actually use, not the federal headline number alone. This is exactly the comparison our fee comparison tool is built for — enter the full cost of each option, including state and add-ons, and see the real total side by side rather than comparing advertised starting prices.

Always check the state filing fee before comparing two products by their federal price alone
If you'll file in more than one state, ask whether the fee applies per state or is bundled
Some products offer free state filing only for their lowest tier — check whether it still applies once you're in a paid tier
Watch for the fee appearing only at checkout, after you've entered most of your information

A note on switching because of price

Discovering a state fee late in the process is one of the more common reasons people consider switching software mid-filing. It's rarely worth it once you've entered significant data — see our guide on switching software mid-season for when it does and doesn't make sense.

Key takeaway Almost every tax software prices state filing separately from federal, and it's the fee most people miss until checkout. Compare total cost — federal plus state plus add-ons — not the advertised federal price alone.

The multi-state situation people don't plan for

Beyond simply living in a state with income tax, a growing number of filers owe state tax in more than one state without realizing it in advance — commonly from working remotely for an out-of-state employer, moving partway through the year, or earning rental or investment income tied to a property in a different state. Each of these can trigger a requirement to file in more than one state, and most software charges the state filing fee separately for each one.

Remote work across state lines

If you worked remotely for part of the year for an employer based in a different state than where you live, the rules for which state taxes that income vary and can genuinely be confusing even for otherwise-simple returns. Some states have reciprocity agreements that simplify this; many don't. This is a specific situation worth checking your state's rules on directly, since it affects both which forms you need and how many state filing fees you'll pay.

Comparing bundled versus à la carte pricing

Some providers bundle a certain number of state filings into a paid tier; others charge for every state regardless of tier. Neither approach is inherently better, but they produce very different total costs depending on your situation, which is exactly why the advertised starting price is a poor basis for comparison if you need to file in more than one state.

A quick way to sanity-check any provider's total price

Before committing to a product, it's worth working through your actual situation on their site as far as you can before payment — most providers let you fill in your full return and only ask for payment at the very end. This lets you see the genuine, itemized total (federal, plus each state, plus any add-ons) before you've spent any money, which is a more reliable number than anything on the marketing page.

Why some filers pay nothing for state at all

If your only state connection is your home state and that state has no income tax, none of this applies to you — you'll only ever pay a federal fee, if any. It's worth confirming your specific state's status directly rather than assuming based on general knowledge, since a small number of additional states tax only certain types of income (like investment income) rather than wages, which changes the calculation depending on your income mix.

Also worth noting: If you have income tied to more than one state — through remote work, a move, or an out-of-state rental — expect to pay a separate state filing fee for each one, and verify the total using the software's own itemized preview before paying, not the homepage price.

If you're deciding between two specific products, plug both total costs into the fee comparison tool above to see the real gap rather than estimating it.
