Why give the IRS an interest-free loan throughout the year? Instead, boost your monthly earnings by changing the amount of withholdings you claim. Kiplinger offers an easy 3-question calculator to help you figure out the right number.

If you want to be more exact, you can follow the 19-page IRS work booklet (PDF), or answer their 30 item online questionnaire.

Once you do that, file a revised W-4 (PDF) with your employer, and start seeing the pay bump within 30 days. — BEN POPKEN
