After you file

The IRS does not email or call taxpayers.  Communication from the IRS is through the US mail.

On the IRS federal tax refund website make sure that you are entering Exactly the Social Security number, Filing Status and the whole dollar amount of your Federal tax refund as shown on the Federal tax return that was filed, not what is shown on a TurboTax screen for your refund.

If over 21 days since being Accepted by the IRS and the tax refund is still Processing you can call the IRS and speak with an IRS agent concerning your tax refund.
Call the IRS:  1-800-829-1040  hours 7 AM - 7 PM local time Monday-Friday
