Once you determine if you want to appeal your determination, you are ready to request an Appeals conference or hearing if you can explain why you disagree.
Consider the following:
If you need help in deciding whether the IRS made an incorrect decision due to misinterpreting the law, check the publications discussing your issue(s) for additional information, or refer to Tax Topics.
If you believe the IRS did not properly apply the law due to a misunderstanding of the facts, be prepared to clarify and support your position refer to the Examination page.
If you believe the IRS is taking an inappropriate collection action against you, or you do not agree with Collection's denial of your offer in compromise, refer to the Collections page.
If you believe the facts used by the IRS are incorrect, then you should have records or other support available to back up your position.
Getting help with this kind of action against the IRS is a good idea. There are several options when it comes to choosing a firm to help you out.
