This form helps your employer calculate the correct amount of federal tax to be withheld from your pay. The consequences of not filling in the IRS Form W-4 correctly can be bad. Using the IRS Form W-4 wisely will save you a lot of trouble. So please avoid the below common mistakes:

- Misspelling your name or SSN in the W-4 Form will most likely result in your employer rejecting it; so make sure the information is entered correctly.

- Proper calculation of the number of deductions is extremely important to avoid surprises during the tax season as you may end up owing money to the IRS. On the other hand, if you overreport your deductions, you will end up with a smaller take-home amount in your paycheck, but a larger tax refund at the end of the year which is like giving the IRS a free loan.

- Make sure you select the correct marital status box as it will also affect the amount of tax withheld from your paycheck.
