The IRS is Aggressive with Liens
If you don't pay your taxes, the IRS establishes a lien against all of your assets (especially real estate). This gives the IRS the legal right to
collect taxes from the sale of your assets, which includes just about everything you own.
Liens Affect Your Possessions, Your Credit, and Your Business
The IRS can file a lien against you, your spouse, and even your company. They have the right to seize your assets.
Liens filed against you by the IRS also show up on your credit report and often prevent you from opening a checking account or borrowing against any assets, like your home. The banks don't want the extra work when the IRS comes in to take your money.
With a Federal Tax lien on your record you can't get a reasonable loan to purchase a car. Think about paying 18-22% interest on a car that is already too expensive. You definitely cannot buy or sell any Real Estate. The list is endless.
