I filed my taxes about 2 weeks ago at h&r block. Knowing I'm single with no dependents, I thought things would go smooth. The man said my W4 forms, which is the paper you fill before starting a new job, where filled out wrong
making it look like I was married All year. My question is, is there Anything I can do about it now? Instead of getting a nice return, I actually owe the IRS money, because of that mistake. Regardless, I worked all year and should have a right to a refund...

#1;you should contact the IRS ASAP; You need to inform it of the error, then determine what the best course of action is. You usually ., as you said, might owe more money than what you need to pay because of the error. In that case, you should make arrangements with the IRS to pay off your taxes as soon as possible.

This is not your case however, aslongas money is owed to you, then,you need to make sure you indicate that when you file taxes, or ask the IRS to grant you an extension so you can file correctly and recover the extra money you paid.


#2;as mentioned above.
