Are IRS interest and penalty charges ever forgiven?

Thank you for your question.  Many people who owe taxes more than five or six years old find that the interest and penalties are more than the original tax.  This is because penalties keep being added for several years.  In fact, there are more than 170 penalties the IRS can levy.  In addition, the IRS compounds interest daily, so that adds up really fast. The answer to your question depends on the type of deal you make with the IRS.  If you enter into an Installment Agreement, you will have to pay the accrued interest, which continues to accrue until the balance is paid in full, but the penalties might be forgiven if you have reasonable cause for being behind in payments.  However, the IRS will not consider your request for abatement of penalties until the underlying tax is paid.  If you file an Offer In Compromise and it is accepted, then your entire liability, i.e. taxes, interest and penalties, is considered paid in full for the lesser amount of the compromise; therefore, the issue of forgiving interest and/or penalties never arises.  Thus, we must first decide the best way to handle your tax problem, then we can deal with the issue of interest and penalties.  To help make that decision you will need to provide us your complete financial data.
