The tax statement came in November and you could not pay it. Then the next one came. Nobody knocked on the door, nothing visible happened, and now you are three years in and trying to work out whether the county can actually take the house, and how long you have.
Delinquent property tax in Oklahoma runs on a calendar, and the calendar is the whole story. This article sets out what happens each year, the one date that catches almost everybody, what it costs to catch up, and what your options are at each stage.
We buy houses with back taxes, so read the last section knowing that. We are not attorneys or tax officials. Dates, interest rates and procedures are set by Oklahoma statute and county practice and they change, so the Tulsa County Treasurer on 918-596-5071 is the authority for your parcel rather than this page. Get your own figures from them before deciding anything.
The annual calendar
Oklahoma property tax runs on a cycle that repeats every year, and understanding it is most of what you need.
- 1 January. The assessment date. Your property is valued as it stands on that day
- Autumn. Statements go out
- 31 December. The full year is due, or the first half if you are paying in two instalments
- 31 March. The second half is due for those paying in halves
The date that catches people
If you miss 31 December, the half-payment option generally goes away. The county cannot accept a first-half payment after that date, so missing December leaves you a full year delinquent rather than half.
People assume they can pay the first half late and catch the second in March. That is not how it works, and it is the single most common misunderstanding about Oklahoma property tax. Our page on Tulsa County property tax dates covers the payment mechanics.
What it costs to be late
Interest accrues on delinquent tax at a rate set by statute, commonly cited as 1.5 per cent per month. Compounding monthly on a growing balance is why a bill people meant to catch up on becomes one they cannot.
Run your own numbers with the Treasurer rather than estimating. They will tell you exactly what is owed today, and that figure is the only one that matters.
What happens as the years pass
Nothing dramatic happens quickly, which is exactly why people let it run.
Year one delinquent. Interest accrues. The county sends notices. You still own the house and nothing has changed about that.
Continuing delinquency. The balance grows. The parcel becomes eligible, after the period Oklahoma statute sets, for the county resale process.
The June resale. Oklahoma counties hold a resale of tax-delinquent property, conventionally on the second Monday in June. Our article on how houses are lost at the county tax sale covers what happens there and what it means.
One procedural point worth knowing: since 1 November 2025, under changes to Title 68 section 3113, payment is required before the auction starts rather than being settled afterwards. That matters if you were relying on turning up on the day.
What you can actually do
- Call the Treasurer and get the exact figure. Free, takes one call, and it is the number every other decision depends on. Guessing high is as unhelpful as guessing low
- Ask about payment arrangements. Counties differ in what they can offer and it is worth asking directly rather than assuming there is nothing
- Check your exemptions. Oklahoma has a homestead exemption and additional relief for some homeowners including older owners on limited incomes. Whether you qualify, and whether it can be applied, is an Assessor question and people frequently do not know they were eligible
- Check the assessment itself. If the valuation is wrong the tax is wrong, and there is a protest process with its own deadlines
- Refinance or borrow against equity, if the equity is there and you can qualify
- Sell. Which brings us to the point of this section
Selling with back taxes owed
The thing most owners do not know: you do not have to pay the taxes before you can sell.
Delinquent property tax is settled from the proceeds at closing by the title company, exactly like a mortgage payoff or a lien. It comes off your side of the settlement statement. You do not need to find the money first, and a buyer is not taking on your debt.
What matters is the calendar. A sale that closes before the resale process reaches your parcel converts your equity into money. A parcel that goes through resale does not. Our page on selling a house with back taxes sets out how it works, and our article on liens generally covers the wider picture.
Work out the equity first
Before deciding anything, do this arithmetic. What the house is worth, minus the mortgage, minus the tax owed including interest, minus any other liens, minus selling costs.
If that number is comfortably positive, you have options and time pressure. If it is negative, selling does not solve it and you need advice rather than a buyer. We will tell you that on the phone.
Where we come in
We buy houses across Tulsa and the surrounding towns with delinquent property tax, sometimes several years of it, and the tax is paid from the proceeds at closing rather than by you beforehand.
Honest position: if you can catch the tax up, or an exemption you did not know about applies, or the assessment is wrong, do that instead. Those routes keep your house and they cost a phone call to find out about. Where we make sense is when the balance has grown beyond reach, when the resale calendar is closing in, or when the tax sits alongside condition problems that make a conventional sale difficult.
Our offer process is free with no obligation, and the net proceeds calculator lets you test it against listing.
The short version

- Missing 31 December generally removes the half-payment option, leaving you a full year delinquent rather than half. This catches almost everybody
- Interest accrues monthly at a statutory rate, commonly cited as 1.5 per cent
- Continued delinquency eventually makes a parcel eligible for the county resale, conventionally the second Monday in June
- Since 1 November 2025 payment is required before the auction starts rather than settled afterwards
- Call the Treasurer for the exact figure before deciding anything. Check exemptions and the assessment too; people frequently qualify for relief they never claimed
- You do not have to pay the taxes before selling. They come out of the proceeds at closing
- Work out the equity first. If it is negative, selling does not solve it
Frequently asked questions
How long can you go without paying property taxes in Oklahoma?
Interest starts accruing immediately and continued delinquency eventually makes a parcel eligible for the county resale process. The exact period is set by statute and the Treasurer for your county is the authority for your parcel.
When is Oklahoma property tax due?
The full year or the first half is due 31 December, and the second half 31 March for those paying in instalments. The assessment date is 1 January and statements go out in autumn.
What happens if I miss the December deadline?
The half-payment option generally goes away, because the county cannot accept a first-half payment after that date. Missing December leaves you a full year delinquent rather than half, which surprises most people.
How much interest is charged on late property tax?
A statutory rate commonly cited as 1.5 per cent per month, compounding on a growing balance. Get the exact figure from the Treasurer rather than estimating.
Can the county take my house for unpaid taxes?
Continued delinquency eventually makes a parcel eligible for the county resale process, conventionally held on the second Monday in June. That is the mechanism, and it takes years rather than months.
What changed on 1 November 2025?
Under changes to Title 68 section 3113, payment is required before the auction starts rather than being settled afterwards. That matters if you were relying on turning up on the day.
Do I have to pay the back taxes before I can sell?
No, and this is the single most useful thing on this page. Delinquent tax is settled from the proceeds at closing by the title company, exactly like a mortgage payoff.
Will a buyer take on my tax debt?
No. It comes off your side of the settlement statement at closing. The buyer receives clear title; you receive what is left after the tax and any other liens are paid.
Can I set up a payment plan with the county?
Counties differ in what they can offer. Ask the Treasurer directly rather than assuming there is nothing available; it costs one call.
Am I missing an exemption?
Possibly. Oklahoma has a homestead exemption and additional relief for some homeowners including older owners on limited incomes. Whether you qualify is an Assessor question and people frequently never claimed relief they were entitled to.
What if the assessed value is wrong?
If the valuation is wrong the tax is wrong, and there is a protest process with its own deadlines. The Assessor's office can explain how and when to file.
Does unpaid property tax affect my mortgage?
It can. Many mortgages require taxes to be kept current, and a lender may pay them and add the cost to your loan. Check your own loan documents or ask the servicer.
What is the county resale?
The process by which counties sell property that has been tax delinquent for the statutory period, conventionally on the second Monday in June. Our article on how houses are lost at the tax sale covers what happens.
How do I find out exactly what I owe?
Call the Tulsa County Treasurer on 918-596-5071, or the Treasurer for your county. They will give you the current figure including interest, and that is the only number worth working from.
Should I sell or try to catch up?
Catch up if you can, or if an exemption applies, or if the assessment is wrong. Those routes keep your house. Selling makes sense when the balance is beyond reach or the resale calendar is closing in.
What if I owe more than the house is worth?
Then selling does not solve it and you need advice rather than a buyer. Work out the equity: value, minus mortgage, minus tax and interest, minus other liens, minus selling costs.
Does a tax lien show up on my credit?
Reporting practices for tax debt have changed over time and vary. A housing counsellor or an attorney can explain what applies to your situation better than a general article can.
Can I sell if the property is already listed for resale?
Sometimes, and the timing is critical. That is a question for an attorney and the Treasurer urgently rather than something to work through slowly.
Will you buy a house with several years of back taxes?
Yes. The tax is paid from the proceeds at closing rather than by you first, and several years of delinquency is a situation we deal with regularly.
Do I have to disclose unpaid taxes to a buyer?
It surfaces in the title search regardless, and the title company handles it at closing. Whether there is a separate disclosure obligation is a question for a real estate attorney.
What about taxes on an inherited house?
The same calendar applies whether or not probate is finished, and unpaid tax accrues while an estate is unresolved. That combination is one of the more common reasons inherited houses reach the resale list.
Who do I call first?
The Treasurer, for the exact figure, and the Assessor, to check exemptions and the assessment. Both are free calls and both come before any decision about selling.
We buy houses with back taxes, so read the last section knowing that. We are not attorneys or tax officials. Dates, rates and procedures are set by Oklahoma statute and county practice and they change, so the Tulsa County Treasurer is the authority for your parcel rather than this page.
Years of back taxes owed?
The tax is paid from the proceeds at closing, not by you beforehand.
- A written offer within 24 hours, not a range on the phone
- No repairs, no cleaning, no fees, and no showings
- If listing would net you more, we say so
No fees, no obligation, and your property is never listed publicly.
