If you owe income or payroll taxes, the I.R.S. may put a tax lien on your property. They do this by recording a Notice of Federal Tax Lien in the county records, either where you live or where you own property, or both. As Nina Olson, IRS National Taxpayer Advocate explains in this video, an IRS lien can cause you all kinds of problems, including wrecking your credit.
In certain circumstances, it is possible to have a tax lien lifted or subordinated, but it is quite a chore and can take 30 days or more, if it can be done at all.
If you have serious tax problems, including having a tax lien, consult a professional for help. Only attorneys, CPA's and enrolled agents are authorized to represent you before the I.R.S.
