How to File a Tax Extension for Form 1040 (2026 Deadlines + 3 Easy Methods)

CPA Stephen Lee explains how to request an automatic six-month tax extension for a Form 1040 using IRS Form 4868 for the 2026 tax season, covering key deadlines and common mistakes that can trigger IRS penalties. He emphasizes that an extension gives more time to file—not more time to pay—and that unpaid taxes after April 15, 2026 may incur interest and late-payment penalties, with the IRS generally expecting at least 90% paid by the deadline. The video walks through estimating tax liability and completing Form 4868 lines for total tax, payments, balance due, and amount paid with the extension. He details three ways to extend: making an electronic extension payment, e-filing Form 4868, or mailing a paper Form 4868 with proof of mailing, plus special rules for taxpayers abroad and disaster relief.
