Tax problems don't just go away. There are options, but before you enter into any type of payment plan with the IRS, remember that if you are in this situation to start with, you probably also owe money to your State tax board. I would suggest that you deal with the state first (after you file your federal return of course). For starters, the IRS is going to ask you what you can afford to pay. If you didn't account for your debt to the State, you will end up in the same situation of not being able to keep up. When you are figuring out what you can pay the IRS, they will allow for the amount of your state tax payments (whereas most States won't). Additionally, next year at tax time, state tax payments are often deductible (if you itemize).
Of course, if you need assistance sorting any of this out, I am happy to help. I am an Enrolled Agent who provides Tax CPR - Compliance, Planning, and Representation. My goal is to help you pay the least amount of taxes legally possible.
