No one wants to delay their federal tax refund. As you certainly don’t, filling out your 1040 form correctly is essential. To that end, it is worth noting some of the common 1040 mistakes – the little slip-ups that aggravate both the IRS and the taxpayer.
Not signing your return. If you file online (and who doesn’t), you have to type your name on the “Your Signature” line in the “Sign Here” section, along with your spouse’s name if you file jointly. If you still file a hard-copy return, you’ve got to sign your name on the “Your Signature” line, and the same goes for your spouse on the “Spouse’s signature” line. No valid signature equals an invalid return.1
Not getting your name right. Believe or not, some people mistype their names as they e-file. More commonly, they enter an old name – a maiden name, for example – that doesn’t match the name linked to this taxpayer identification number. If you’ve changed your name, the Social Security Administration (and other federal agencies, as applicable) need to know that.1
Missing the filing deadline(s) applicable to you or your business. Is your company an S corp? That means you will probably need to file a Form 1120S by March 15. Is it a sole proprietorship? That means you have until April 15 to file a Form 1040C. If you are new to making estimated tax payments, you have hopefully pored over Form 1040-ES with a tax professional to figure out how much tax is due by each quarterly payment period.2
