How do I file a federal tax return for free with IRS Free File in the United States?

IRS Free File is a way to prepare and e-file a federal tax return at no cost: Start at IRS.gov/freefile. Opening a partner's own website first is not IRS Free File. Guided tax software on that page is for adjusted gross income of $89,000 or less. Each partner sets its own rules. Free File Fillable Forms are for any income, and they do not file a state return. The page says you can file only the current year this way, not a prior-year return. The IRS does not endorse one partner. Confirm on the official page.
