https://turbotax.intuit.com What are Tax Extensions? There may be a tax year when you can't just get that return finished by the April deadline. Luckily, the IRS offers automatic extensions of time to file all types of tax returns. For most personal returns, the filing deadline for tax returns is April 15 of each year. However, by filling out form 4868 and mailing it to the IRS by April 15th, you can get an extra six months to file your tax return without incurring penalties. Learn more about IRS tax extensions for individual, business, corporate, estate and trust tax returns, as well as failure-to-file and failure-to-pay IRS penalties, with this helpful tax tip video from TurboTax.
