Frequently Asked Questions

Do I have appeal rights after a lien is filed?
Yes, and they run on a clock. The Internal Revenue Manual states this letter is issued to notify taxpayers of their right to a Collection Due Process hearing under IRC 6320 -- the lien-filing counterpart to the levy right under IRC 6330. Publication 5341 states a CDP hearing is requested within 30 days after a Notice of Federal Tax Lien Filing, and that the process preserves the right to petition Tax Court. The MUST FILE BY date on your letter governs. This describes internal IRS guidance and a published roadmap; the instructions printed on your own letter are what you act on.
How does a tax lien affect my credit?
While tax liens are no longer reported on credit reports as of 2018, they are public records that lenders and employers can find. They attach to all your current and future property and make it difficult to sell assets or get financing.
How do I remove a tax lien?
Pay the balance in full and request lien withdrawal, set up a payment plan and request lien withdrawal under certain conditions, or settle with an Offer in Compromise and request withdrawal.
