This often is a problem for new wives. Many women change their surnames when they marry. That's also an option for spouses in same-sex marriages, which the IRS now recognizes. If you didn't alert the Social Security Administration of your name change soon after your wedding, do so now so that your new name won't cause a problem when you file your first joint tax return.
And if marital bliss doesn't last and you change your name after a divorce, make sure Uncle Sam's appropriate agencies know that, too.
4. Direct deposit dangers
Taxpayers can have a refund directly deposited into multiple bank accounts. This option is a great way to save your refund money, but the more numbers you enter on a tax form, the more chances you have to enter them incorrectly. And a wrong account or routing number could cause you to lose your refund entirely.
You can divide your refund into three accounts by filing Form 8888 along with your individual return. It's not a difficult document to complete, but if you put in wrong account numbers, your refund could end up in someone else's account or be sent back to the IRS. Either way, you might not be able to retrieve your refund because there is no IRS procedure for replacing lost electronically transferred funds.
Incorrect account numbers aren't just a problem when a refund is split multiple ways. Even if your refund is going to just one account, make very sure you enter your account and bank routing numbers correctly.
5. Additional income, additional filing work
Did you have a side job this year? If so, as a contractor you probably received a Form 1099-MISC detailing the extra earnings.
What about savings and investment accounts? For these, you should have received Form 1099-INT and Form 1099 DIV statements.
In each 1099 instance, the IRS knows precisely how much extra money, either as wages or unearned investment income, you made as soon as you did, thanks to the copies of your 1099 forms that went to the tax agency.
