If you have filed your returns, but didn't pay what was owed, you are still creating significant financial risk for yourself.  You may think, "I will catch up next year."  Penalties and interest for unpaid taxes can balloon quickly, and before you know it, you have a larger, even more challenging, financial problem.  

Payment plans may be on alternative, but if you deal directly with the IRS you are at a disadvantage because only they know how far they are willing to bend.  We deal with the IRS on a regular basis and have experience negotiating payment plans.  Our knowledge becomes your advantage.
