More and more people are using the IRS' e-File option to file tax returns. Whether you use do-it-yourself tax preparation software or hire a professional tax preparer, filing your federal taxes using e-File has distinct benefits. For starters, taxpayers who file tax returns by e-File have far fewer inaccuracies in their tax returns. That means your tax return gets processed with fewer delays. The main benefit of e-File is faster refunds. If you are due a refund, file your tax return using e-File, and opt to have your refund deposited to your bank account electronically, you'll get your refund in about two weeks—four weeks sooner than people who file paper forms.
