Each Oklahoma county holds its annual tax resale on the second Monday of June, or starts it within that week when the treasurer runs it online (68 O.S. 3105, 3125). A parcel is sold there once its taxes have been a lien and unpaid for three years or more from the date they first came due, unless the 3105(B) exemption for certain low-income senior or disabled homeowners in counties of more than 100,000 people applies, and the owner can still redeem at any time before the auction starts (68 O.S.
3105, 3113). During a Governor-declared Catastrophic Health Emergency, the county commissioners, on the treasurer's written request, must postpone the sale for up to one year (68 O.S. 3105(A), 3148(C)). Laws 2008, c. 82 repealed sections 3107 through 3112 and others around them, and nothing left in Article 31 sells a tax certificate to an investor, so the deed is what you are buying. Here is the work to do on a single parcel before you bid.
The treasurer publishes the resale notice once a week for the four weeks before the sale (68 O.S. 3127). Each entry describes the land, names the record owner shown in the assessor's records as of the preceding December 31 or later, gives the date the taxes first came due and the years left unpaid, and states at least a combined total of taxes, penalties, interest and costs. Note that total, then confirm the current amount due with the treasurer's office closer to sale day.
A parcel must sell for at least two-thirds of its assessed value for the current fiscal year, or the total taxes, penalties, interest and costs due, whichever is lower (68 O.S. 3129(C)). Say $2,400 is due and the assessor carries the parcel at $9,000 assessed value, which is a different figure from market value. Two-thirds of $9,000 is $6,000, so the floor is $2,400. At $3,000 assessed, two-thirds is $2,000, so the floor drops to $2,000. One exception overrides that math: if a municipality has given the treasurer notice of its right, the same subsection places a reserve minimum bid covering all taxes, abatement costs, penalties, interest and costs due to a municipality. Ask the treasurer whether a reserve applies to your parcel.
The winning bid is paid in cash or certified funds, and an online resale may accept online payment (68 O.S. 3129(A)). On top of the bid, the treasurer collects the deed fees set by 28 O.S. 43 and enough to cover what the county spent preparing, listing and advertising that tract (68 O.S. 3131(B)). Section 3128 also directs the treasurer to collect the resale list's publication fees from the purchaser, so ask how the county itemizes them. If the sale runs online through a hired firm, the statute adds the online auctioneer's cost to the sale of each property (68 O.S. 3129(B)). Read the county's bidder instructions for any recording or local fee, and write every charge into your maximum bid.
The treasurer sends the resale list to the Oklahoma Health Care Authority, which returns a list of the parcels carrying its liens, and the treasurer must make that list available to potential buyers at the resale (68 O.S. 3129(D)). The statute sets no earlier deadline, so the list may first appear on sale day. On the treasurer's request, OHCA files a release of its lien on a parcel that fits the definition of blighted property in 11 O.S. 38-101, and the release does not extinguish the debt, which OHCA may still enforce through any legal means available to it. Article 31 does not expressly address an OHCA lien that was never released. Whether the state-claims clause of 68 O.S. 3131(A) or the state-lien priority rule of 68 O.S. 3142 reaches one is a legal question, so a parcel on that list is worth a title attorney's review before you bid.
The deed vests "an absolute and perfect title in fee simple," subject to all claims the state may have had on the land for taxes or other liens or encumbrances (68 O.S. 3131(A)). Several other sections limit it, including these four.
The deed conveys only the surface, the surface rights and the mineral interests owned by the surface owner, so check the title for a mineral severance (68 O.S.
3119). It is ineffective to extinguish the mortgage of a mortgagee to whom no notice was sent (68 O.S. 3127). When the treasurer cannot find a mortgagee of record's address through reasonable diligence, an affidavit filed with the county clerk, together with publication, suffices as notice, and neither a failure to send notice to a mortgagee of record nor anyone's failure to receive notice invalidates the resale (68 O.S. 3127). Ask the treasurer for the certified-mail record and check the county clerk's records for any affidavit.
The tax always ranks behind a mortgage or lien of the State of Oklahoma, the Commissioners of the Land Office, or any commission, board or officer with power to loan public funds or any funds under the state's control on real estate security (68 O.S.
3142). Usual restrictions and covenants running with the land that limit use or the type, character and location of buildings, covenants against nuisances, and other similar restrictions survive as they would against a voluntary buyer, when they appear in a deed in the chain of title in a city or incorporated town or one of its additions or subdivisions (68 O.S. 3145, 3146).
The treasurer must file the resale return and deliver the deed within 30 days of the sale (68 O.S. 3131(A)). Once the deed has been recorded for a year, no action to set it aside may be started, and the former owner and the deed holder alike must sue to recover possession within one year of recording (68 O.S. 3131(A), 3141). An action to avoid the deed also requires paying or tendering all taxes, interest, penalties, costs and expenses first (68 O.S.
3141). A challenger must show clearly that a step the deed presumes was entirely omitted, show a right to redeem when the deed was made, and tender in open court, for the deed holder's use, what redemption would cost when the suit is filed or the defense pleaded, or the case is dismissed; the article directs courts to construe it liberally so its proceedings are sustained (68 O.S.
3140). Persons under legal disability have one year after the disability ends to redeem (68 O.S. 3131(A)); the parallel clause in 3113 covers minors and incapacitated or partially incapacitated persons, counting mental incapacity only.
When a parcel sells for more than the taxes, penalties, interest and costs due, the treasurer notifies the Oklahoma Tax Commission within 30 days. Within 60 days of that notice, the Commission reports any state tax owed on the parcel, and the treasurer remits the lesser of that amount or the excess. The rest is held for the record owner shown in the county records as of the day the resale began, claimable for one year and then credited to the county resale property fund. An assignment of that right made on or after the day the resale began is void (68 O.S. 3131(C) and (D)).
