Tax preparation software is a guided digital tool that helps you complete and file your federal and state income tax returns. Instead of working through IRS instruction booklets and paper forms, you answer a series of questions — income, deductions, credits — and the software fills in the appropriate forms, calculates what you owe (or your refund), and submits the return electronically to the IRS and your state.
That is all it is. The marketing around it — mascots, guarantees, “Live CPA chat,” animated refund counters — is packaging on top of a form-completion service.
This is not tax advice. Content covers software features and pricing, not tax strategy. Tax laws change annually — verify current pricing and eligibility with vendors before filing.
What tax preparation software actually does
- Asks questions about your income sources, filing status, and deductions through a guided wizard
- Populates IRS forms — primarily Form 1040 and any required schedules (Schedule C for freelancers, Schedule E for landlords, Schedule D for investors, etc.)
- Calculates your tax liability or refund using the current year’s tax tables and rates
- Checks for errors — flagging missing information or mathematical inconsistencies before you file
- Submits electronically — the IRS prefers e-filing; returns are typically processed faster than paper
- Imports prior-year data — to pre-populate name, address, W-2 employer information
It does not provide tax advice, tax planning, or legal guidance. If you need those services, you need an enrolled agent (EA), certified public accountant (CPA), or tax attorney — not software.
The three categories of tax software
Consumer-grade software — for individuals and the self-employed. Examples: TurboTax, H&R Block, FreeTaxUSA, Cash App Taxes, TaxAct, TaxSlayer. These handle Form 1040 and common schedules. Consumer tools cannot file 1120-S (S-Corporation returns) or 1065 (Partnership returns) — except TurboTax Business (Windows only) and TaxAct Business.
Non-resident alien software — specifically for individuals on F-1, J-1, H-1B, and other non-immigrant visas who must file Form 1040-NR instead of Form 1040. Consumer tools explicitly do not support 1040-NR. The two dominant options are Sprintax ($59.95+ federal + $49.95 per state) and Glacier Tax Prep.
Professional-grade software — for CPAs and tax preparers handling multiple clients. Examples: Drake Tax, ProSeries (Intuit), Lacerte (Intuit), UltraTax CS (Thomson Reuters). These handle every return type and cost $1,750-$10,000+ per year. Not relevant for individual filers.
What the “free” tiers actually cover
Every major consumer tax software advertises a “Free Edition” or “Free Filing.” The coverage varies dramatically:
| Software | Free federal covers | State filing cost |
|---|---|---|
| Cash App Taxes | W-2, Schedule C, D, most forms | $0 (one state) |
| FreeTaxUSA | W-2, Schedule C, D, E, most forms | $14.99 |
| TurboTax Free Edition | W-2 + EITC + CTC only (~37% of filers qualify) | $0 |
| H&R Block Free Online | W-2 + 1099-G + student loan interest | $0 |
| TaxAct Free | W-2 + basic situations | $39.99 |
| IRS Free File partners | Varies by AGI (under $84,000 threshold) | Varies |
The FTC found in its action against Intuit (Docket No. 9408, Jan 2024) that approximately 63% of users who started TurboTax’s Free Edition encountered an upgrade prompt. The factual findings stand on the record even after the order was vacated procedurally.
IRS Direct File (cancelled for 2026)
IRS Direct File was the IRS’s own free filing pilot, available in approximately 25 states for the 2024-2025 filing season. It was cancelled for the 2026 filing season (federal returns filed in early 2026 for tax year 2025), confirmed by Federal News Network reporting in November 2025. If you used Direct File in the previous season, you need to choose a commercial option. The closest free replacements are Cash App Taxes ($0 federal + state) or FreeTaxUSA ($0 federal + $14.99 state).
Do I need software, a CPA, or paper forms?
Use software if: your return is a W-2 with standard or itemized deductions, freelance Schedule C income, rental property Schedule E, investment gains Schedule D, or any combination of these without business entity complexity.
Use a CPA or EA if: you have an S-Corporation (1120-S), a partnership (1065), significant business complexity, an international tax situation beyond a simple expat return, or you are under IRS audit or received a CP2000 notice.
Use paper if: you specifically cannot use electronic filing, have a very unusual return situation, or prefer paper for personal reasons. There is no cost advantage — paper processing takes longer.
