There should be no question about hiring an attorney for an IRS debt settlement. The tax code is far from clear and easy to understand as a result of years of constant tinkering by Congress. This has resulted in an agency that, by law, does not have to play nice with a delinquent tax payer.
If you're ignoring the letters that the IRS is sending you, you're in for a rough ride. You'll find that after ignoring them for a year, the IRS will have liens on any property you own, garnished paychecks or put a levy on your bank account as well as taken back any refunds after the debt started. In short, the IRS will do anything they can to get their money. Compare this with the fact that a creditor can only harass you via the phone and mail but cannot touch your property unless they take you to court for a judgment. Truly you do not want to ignore contact from the IRS if you owe money on a return.
There are three main types of settlements offered by the IRS. Each process has their pros and cons that come with. Choosing wisely is the name of the game, which is why it's important to hire an experienced tax attorney.
The aforementioned settlements are just the tip of the iceberg. Plans are just as varied as the tax code that brought you to the point of owing money. Negotiating them in your favor is difficult at best. Hiring a tax attorney that knows the ins and outs of the process is your best bet at owing the least amount. The best part about hiring legal help is knowing that the IRS won't be harassing you anymore.
