Am I having the correct amount of tax withheld from my paycheck?
It is important that you properly estimate your tax withholding. If an insufficient amount of taxes is withheld, you may end up owing a substantial sum, including penalties and interest, when you file your tax return. Choosing the correct withholding amount for your salary or wages is a matter of completing Form W-4 worksheets, providing an updated Form W-4 when your circumstances change, and perhaps becoming familiar with IRS Publication 919, which deals with withholding.
Two factors determine the amount of income tax your employer withholds from your regular pay: the amount you earn, and the information regarding filing status and withholding allowances that you provide your employer on Form W-4. If you accurately complete all Form W-4 worksheets and you do not have significant non-wage income (e.g., interest and dividends), it is likely that your employer will withhold an amount close to the tax you owe on your return. In the following cases, however, accurate completion of the Form W-4 worksheets alone will not guarantee that you will have the correct amount of tax withheld:
When you are married and both spouses work
When you are working more than one job
When you have non-wage income, such as interest, dividends, alimony, unemployment compensation, or self-employment income
When you will owe other taxes on your return, such as self-employment tax or household employment tax
When your withholding is based on obsolete W-4 information for a substantial part of the year (e.g., you've gotten married, gotten divorced, gained a dependent, experienced income fluctuations)
To ensure that you have the correct amount of tax withheld, try the IRS withholding calculator. It should help you compare the total tax to be withheld for the year to the tax you anticipate owing on your return. It can also help you determine any additional amount you may need to withhold from each paycheck to avoid owing taxes when you file your return. Alternatively, it may help you identify if you are having too much tax withheld.
