The W4 calculator helps increase your return. I would like to reduce my return due to the Foreign Earned Income credit. How can I do that?
Your tax return is the form you send to the government that shows your income and calculates your tax. The money the government sends back to you is your refund.
There are many W-4 calculators. Which one are you using? Try the Tax Withholding Estimator on the IRS web site.
