Finding out how much you owe can be done in a few ways:
1) You can show up at your local IRS office or you can give the IRS a call. You can use IRS.gov to find out where your closest IRS office is or just call the national 1-800 number which is 1-800-829-1040.
2) If you feel you owe at least $7500 dollars you can work with a tax resolution firm which can complete the inquiry for you as typically these firms are staffed with tax resolution experts who have years of experience requesting the status of taxpayer accounts.
3) You could also complete the request process yourself by requesting from the IRS a "Record of Account"and "Account Transcript." In this case, you will need form 4506T or the form to "Request for Tranof Tax Return." If you need information on your account older than 4 years, then Form 4506 is used for a more comprehensive snapshot of your IRS account and will cost you about $57 dollars per return.
Form 4506T will give you information in regards to:
-An Account Tranfor the last 3 years including the current year
-A Record of Account (liabilities vs payments and other adjustments).
Here is the Do-It-Yourself Information:
* Complete Form 4506-T
* Define whether it is for an individual (1040), partnership (1065), or business (940) on line six
* Mark 6C on the form for a "Record of Account"
* Sign, Date, and then send to the correct IRS address (find it on 2nd page of form)
*Make sure to follow the directions on the form and call the IRS or your tax professional if you have any questions.
