1. Silly typos
If you spell your name wrong or reverse any digits in your Social Security number (SSN) or for someone else on your return, the Internal Revenue Service (IRS) will notice. Sloppy handwriting can cause such errors, but so can being in a hurry. The IRS includes these kinds of typos on its list of common taxpayer mistakes and any one of them is enough to delay your refund.
2. Math mistakes
Tax returns include lots of math calculations, and the trickle-down theory applies. If you get one calculation wrong—like incorrectly adding, instead of subtracting, deductions—the math error trickles down to later calculations so that your tax return has inaccuracies. Double-check your math to prevent miscalculations and the delays they can cause. Better yet, e-file your return and let trusted software do the calculations for you.
3. More than one filing status
Are you: Married? Divorced? Head of Household? You might think several of these descriptions apply, but that's not the way it works for taxes. You only get to select one filing status. Filing-status questions are not simply seeking personal information. Your status determines your filing requirements, standard deductions and tax amounts. It pays to understand the different status options and check the correct one for your circumstances—you may end up seeing your refund faster.
4. Incorrect line entries
If you fill out your tax forms by hand, it's easy to enter numbers on the wrong lines. This may seem like a small matter, but if you accidentally enter your alimony received amount one line off, it appears as business income. The IRS will naturally be confused because you will likely be missing other forms for business income and delay processing your tax return until the mistake is cleared up.
5. Early or last-minute tax filing
If you file too early, some of the tax forms you need may not be finalized for handling yet by the IRS. This delays your refund since the IRS won't process a return until their software is ready to handle all necessary tax forms. But filing at the last minute can be just as problematic. If you get the return in just before the tax deadline, you're part of the grand swarm of last-minute filers. The sudden glut of tax returns can cause processing delays.
Best tip: file an electronic return
Electronic filing (e-filing), prevents many common taxpayer missteps that delay refunds, like illegible writing, math errors and entering info on the wrong lines, but e-filing also speeds up your refund even if you haven't made any errors.
Paper returns are processed manually, which usually takes between four and six weeks. Each year the IRS warns taxpayers of delays in processing paper returns, suggesting that the minimum turnaround time can often be as long as seven weeks.
