How to File Taxes Online for Free in 2026 (All Options Explained)

The Two Main Ways to File Federal Taxes for Free

There are two legitimate, IRS-sanctioned paths to free federal tax filing: IRS Free File (a government program) and Free Fillable Forms. Beyond those, several private software companies offer genuinely free filing for simple returns. Here’s how each works.

Option 1: IRS Free File

IRS Free File is a partnership between the IRS and private tax software companies. If your adjusted gross income (AGI) is $79,000 or below (2025 threshold), you can use full-featured tax software through the IRS Free File program — completely free, including state returns in some cases.

Go to irs.gov/freefile to see the participating software partners and their eligibility requirements. Each software company sets its own additional criteria (age, state, etc.), so you may need to check a couple of options to find the right fit.

Important: Don’t go directly to the software company’s website — start at irs.gov/freefile to ensure you get the free version. Going directly often leads to paid products.

Option 2: Free Fillable Forms

IRS Free Fillable Forms is available to all taxpayers regardless of income. It’s essentially the actual IRS tax forms in digital form — you fill them out yourself with no interview guidance. This works well if you’re experienced with tax forms and have a straightforward return. It does not support state returns.

Option 3: Free Private Software

Several private companies offer genuinely free federal (and sometimes state) filing outside of the IRS Free File program:

Cash App Taxes: Free federal and state for most return types — no income limit, no upsells
FreeTaxUSA: Free federal for all return types including freelance and investments; $14.99 for state
TaxAct: Free federal for simple returns (income limits apply)

What Qualifies as a ‘Simple Return’?

Most free filing options work well when you have: W-2 income only (or mostly), standard deduction (no itemizing), no self-employment or freelance income, no rental property income, no complex investment sales, no foreign income. If your situation is more complex, FreeTaxUSA is typically the best free option since it handles Schedule C, D, and E at no federal cost.

Can You File State Taxes for Free Too?

Some states have their own free filing programs. California (CalFile), Massachusetts (MassTaxConnect), and several others offer direct free filing through state websites. Check your state’s Department of Revenue website to see what’s available. Cash App Taxes is also free for state filing in most states.
