The envelope from the county treasurer is the one people stop opening. It arrives, it goes on the counter, and a few months later there is a stack of them. Meanwhile the number inside keeps growing, and the language gets more serious every time.
If you are behind on property taxes in Colorado, the situation is more workable than it feels, but only if you understand the clock you are actually on. Most sellers we talk to either think they have already lost the house or think nothing will happen for years. Neither is quite right.
How Colorado’s Delinquent Tax Timeline Works
Property taxes are due January 1 and become delinquent on June 16 of the same year. Interest starts accruing at that point, and the property becomes eligible for that year’s tax lien sale.
By September 1, the treasurer is required to mail you notice, and the delinquency gets advertised in a local newspaper. The sale itself happens in the fall, generally by the second Monday in December. In Jefferson County it lands in November, and El Paso County runs on a similar schedule.
So the gap between missing a payment and seeing your address in the newspaper is roughly six months. That is faster than most people expect.
What a Tax Lien Sale Does and Does Not Mean
Here is the part that causes the most unnecessary panic. Colorado counties do not auction your house at the tax lien sale. They auction the lien.
An investor pays your delinquent taxes, interest, and fees, and in exchange receives a certificate that earns interest. You still own the house. You still hold title. You can still sell it, refinance it, or live in it.
What you have picked up is a debt against the property that grows at a rate set by statute, and a deadline.
Three Years Sounds Longer Than It Is
Colorado gives you a three-year redemption period after the lien is sold. Redeeming means paying the original delinquent amount, the redemption interest, and any subsequent years of taxes the lien holder has paid on your behalf.
That last piece is what quietly ruins people. If you were behind in 2024 and you are still behind in 2026, the certificate holder has likely been paying each year’s taxes as they come due, and every one of those payments is added to your redemption figure with interest. The number does not sit still for three years. It compounds.
After the redemption period expires, the lien holder can start the process that ends with you losing the property. Colorado overhauled that process recently, and it now runs through a public auction rather than a straight transfer of deed, with any surplus above what is owed going back to the former owner. That is a meaningful protection, but it is a consolation prize, not a plan. Your county treasurer’s office can tell you exactly where your parcel sits in the sequence, and calling them is free.
Yes, You Can Sell a House With a Tax Lien on It
This is the question we get most often, and the answer is straightforward. A tax lien does not prevent a sale. It gets paid out of the proceeds at closing, the same way a mortgage payoff does.
The title company pulls the payoff figure from the treasurer, the amount comes off the top, and you receive whatever is left. If your equity covers what is owed, the problem resolves itself at the closing table. Many Colorado homeowners who are years behind on taxes still walk away with money, because Front Range values have carried them.
Where a Traditional Listing Gets Complicated
Listing is often the right move, and if your house shows well and your timeline is comfortable, you should list it.
The friction shows up when the two problems overlap. Houses fall behind on taxes for the same reasons they fall behind on maintenance, so the property that has unpaid taxes is frequently the property that needs a roof, or has a tenant in it, or has not had a working furnace since last winter. Deferred maintenance limits your buyer pool to people who can get financing on it, and appraisals and inspections on a neglected house tend to generate repair demands you cannot fund while you are already behind.
Add a redemption deadline to that, and a deal falling through in week six stops being an inconvenience.
When Selling As-Is for Cash Makes Sense
A cash sale is worth considering when the redemption window is genuinely close, when the repairs needed to list would cost money you do not have, or when the certainty of a set closing date matters more to you than squeezing out the last few percent of market value.
That trade is real and we will not pretend otherwise. You are exchanging some price for speed, certainty, and the elimination of financing risk. Whether that is a good deal depends entirely on what the alternative looks like from where you are standing.
How We Handle Houses With Back Taxes
We buy houses as-is across Denver and the Front Range, including properties with liens, unpaid taxes, and repairs nobody wants to make. We pull the payoff figures up front so the numbers you see are the numbers you get, and we close on the date that works for your situation rather than a lender’s.
If it would help to see how our process works or read what other Colorado sellers have said before you talk to anyone, both are worth a few minutes.
Behind on taxes and not sure how much runway you have left? Request a cash offer and we will walk through your timeline and your numbers with you, or get in touch if you would rather just ask a question first. This is general information and not legal or tax advice, so confirm your specific redemption dates with your county treasurer.
