Most people overpay for tax software. Not because the software is bad — because they buy the tier the upsell funnel pushes them into, not the tier their return actually needs. This guide is the no-spin version: what’s genuinely free, what the paid tiers really cost, and the dollar line where hiring a human beats doing it yourself.

What’s actually free in 2026

Three routes to a $0 federal return:

1. IRS Free File. Guided software from partner companies, available if your adjusted gross income is below the program threshold (in the low-to-mid $80,000s in recent years — check the current figure). Full-featured for most common situations.
2. IRS Direct File. Where available, this lets eligible taxpayers file directly with the IRS at no cost. Coverage of states and tax situations is still expanding, so confirm your state and forms are supported.
3. Commercial free tiers. Genuinely free for simple W-2 returns — but “simple” is defined narrowly. Add student loan interest, an HSA, unemployment income, or a single stock sale, and most products force an upgrade. Read the included-forms list before you type a single number.

The trap: starting a return in a “free” product, investing an hour of data entry, then hitting the paywall at form three. At that point most people pay rather than start over. The vendors know this. It’s the business model.

The paid tiers, honestly priced

Prices below are the typical 2026 ranges. Vendors change pricing constantly and discount early in the season — treat these as illustrative and confirm current pricing before you buy.

Archetype	Typical federal price	State return	Best for	Watch out for
Free tier (commercial)	$0	$0–$40	Single W-2, standard deduction	Narrow definition of “simple”; paywall appears mid-return
Deluxe tier	$40–$70	$40–$70	Homeowners, itemizers, HSA/child credits	Upsell prompts on every other screen
Premium/investor tier	$70–$110	$40–$70	Stock sales, crypto, rental income	Still no judgment calls — just more forms
Self-employed tier	$90–$130	$40–$70	Schedule C, 1099 income, quarterly estimates	Priced like a CPA consultation, without the consultation
Software + expert help	$150–$400	Included or extra	Anyone who wants a human review	At this price, compare against a local CPA directly

Add state filing and the realistic total for a freelance return lands at $130–$200. File early — most vendors raise prices 10–20% as the deadline approaches.

The DIY vs CPA breakeven math

Here’s the honest comparison. DIY software for a moderately complex return costs roughly $60–$200 and three to six hours of your time. A CPA for the same return costs $300–$600.

The CPA wins when any of these is true:

• Self-employment income above ~$20,000–$30,000. Deduction strategy, retirement account choices (SEP-IRA vs Solo 401k), and the home-office judgment call routinely save more than the fee.
• Equity compensation. RSUs, ISO exercises, and ESPP sales are where DIY filers make four-figure mistakes. Cost basis errors on stock sales are the single most common expensive error we see.
• Rental property or a home sale. Depreciation recapture and exclusion rules have real traps.
• Multi-state income. Software handles the mechanics; it won’t tell you which state’s rules actually favor you.
• You hate doing it. Six hours of your time has a dollar value. If you’d earn more than the fee difference in those hours — or just refuse to spend a weekend on it — the math is done.

DIY wins when your return is: W-2 income, standard deduction, maybe some interest and a few stock sales with clean cost basis reporting. That describes the majority of filers, and paying $400 for a CPA to enter the same numbers is wasted money.

Features that matter (and ones that don’t)

Worth paying for:

• Import of W-2s and 1099s. Kills data-entry errors, the most common source of amended returns.
• Prior-year carryover. Capital loss carryforwards and depreciation schedules must flow year to year.
• Audit support with actual representation. “Audit guidance” (a FAQ page) is worthless. “Audit defense” (a human who deals with the IRS) is a real product — read which one you’re getting.
• Quarterly estimated tax calculation if you’re self-employed.

Not worth paying for:

• Refund advances. You’re borrowing your own money, and the “no fee” versions often route your refund through their products.
• Maximum-refund guarantees. Every competent product computes the same tax from the same inputs. The guarantee is marketing, not math.
• Upsold “expert review” on a simple return. If your return is simple enough for the free tier’s forms, there’s nothing meaningful to review.

Who should skip paid software entirely

If your income qualifies for IRS Free File or Direct File and your situation is covered, paid software is a donation to a shareholder. Start with the free government options every year; only move to a commercial product when a specific form or feature you need isn’t supported.

And if your finances have crossed into CPA territory — business income, rentals, equity comp — stop optimizing between software tiers. The real comparison is software versus professional, and the professional usually wins on the first complicated return.

The bottom line

Match the tool to the return, not to the marketing. Simple W-2: file free through the IRS programs. Moderate complexity: mid-tier software, bought early, decline every upsell. Real complexity: a CPA, whose fee is often recovered in the first year of deductions and avoided mistakes. The most expensive option is the one that’s wrong for your situation — in either direction.
