Estimated Taxes

Taxes must be paid as you earn or receive income during the year, either through withholding or estimated tax payments. If the amount of income tax withheld from your salary or pension is not enough, or if you receive income such as interest, dividends, alimony, self-employment income, capital gains, prizes and awards, you may have to make estimated tax payments. If you are in business for yourself, you generally need to make estimated tax payments. Estimated tax is used to pay not only income tax, but other taxes such as self-employment tax and alternative minimum tax.

If you don’t pay enough tax through withholding and estimated tax payments, you may be charged a penalty. You also may be charged a penalty if your estimated tax payments are late, even if you are due a refund when you file your tax return.

Foreign Account Tax Compliance Act (FATCA)

The Foreign Account Tax Compliance Act (FATCA), which was passed as part of the HIRE Act, generally requires that foreign financial Institutions and certain other non-financial foreign entities report on the foreign assets held by their U.S. account holders or be subject to withholding on withholdable payments. The HIRE Act also contained legislation requiring U.S. persons to report, depending on the value, their foreign financial accounts and foreign assets.
