South Carolina

What you are buying: the property, subject to redemption

There is no tax lien certificate in South Carolina. Most counties collect delinquent real property taxes under Chapter 51 of Title 12, the alternate procedure, which ends in a public auction of the parcel itself. The officer charged with collecting delinquent taxes levies on the property and sells it at public auction at the courthouse or another convenient place in the county, and the price is payable in full on the day of the sale by cash, cashier's check, certified check or money order (S.C. Code § 12-51-50).

What the winning bidder walks away with that day is a receipt, not a deed (§ 12-51-60). The defaulting taxpayer, anyone the owner has conveyed to, and any mortgage or judgment creditor may redeem within twelve months from the date of the sale (§ 12-51-90(A)). Only if nobody does does the collector make out a tax title to you, within thirty days of the end of the redemption period or as soon as possible after that (§ 12-51-130). Until then the property is not yours to enter, rent or repair.

The road to the sale starts early in the year. Taxes unpaid before January 16 (or thirty days after the bills are mailed, whichever is later) take a 3% penalty; another 7% is added on February 2 and another 5% on March 17, and after that the treasurer issues a tax execution for collection under Chapter 51 (§ 12-45-180(A)). From April 1 the collector mails a delinquency notice, and thirty days later takes exclusive possession of the property by certified mail, restricted delivery, or by posting it as “seized” if the mail comes back (§ 12-51-40(a)–(c)). Most counties then sell in the autumn: Richland County's 2026 sale runs on November 2 and 3, 2026.

How the bidding works: up, from a bid the county must place

Every parcel opens with a bid the law requires. The officer selling the property must submit a bid on behalf of the county's forfeited land commission equal to all unpaid taxes, penalties, assessments and costs, including the taxes levied for the year in which the redemption period begins (§ 12-51-55). That is the floor, and it is usually what the advertised “amount due” in the sale list represents. Investors then bid the price up, and the property goes to the highest bidder (Richland County, Tax Sale).

Nothing is bid down. The rate is fixed by statute and nobody competes on it, so the only way to win a desirable parcel is to pay more for it. On good property in the larger counties that means bidding far above the opening figure, and the amount above what is owed does not go to the county: after taxes, penalties and costs are paid, the excess is held by the collector as an overage (§ 12-51-60).

If one owner has several parcels on the list, the collector stops selling them as soon as enough money has been raised to cover all of that owner's delinquent taxes (§ 12-51-50). The parcel you came for can simply be withdrawn in the middle of the sale.

Counties set their own mechanics. Richland requires online registration by October 26 with a $50 fee, and full payment on the day of the sale by cash, cashier's check or bank wire (Richland County). Charleston registers bidders through its online platform and publishes the listing as a spreadsheet (Charleston County). If a winning bidder does not pay, the bid is cancelled, the property goes to a later sale, and the bidder owes up to $500 in damages (§ 12-51-70); Charleston adds that a defaulting bidder's other bids are void and that they are barred from future sales.

What a South Carolina bid actually pays

When the property is redeemed, the collector cancels the sale and refunds your purchase price plus the interest in § 12-51-90 (§ 12-51-100). That interest is a lump sum on the whole amount of your bid, set by the part of the redemption year the owner redeems in, and it relates back to the beginning of the redemption period (§ 12-51-90(B)):

3% of the bid if redeemed in the first three months; 6% in months four to six; 9% in months seven to nine; 12% in the last three months.

Because it is a lump sum, the annualised figure swings wildly. A redemption in week three still pays the full 3%; a redemption on the last day of month ten pays 12% for ten months' use of your money. The rate never exceeds 12% in total, because the redemption window never exceeds twelve months.

Then comes the sentence that most yield spreadsheets miss: in every redemption, the interest due must not exceed the amount of the bid submitted on behalf of the forfeited land commission (§ 12-51-90(B)). The interest is calculated on your whole bid, but it is capped at the opening bid. Take a parcel that opens at $1,500 and that you win at $20,000. Redeemed in month two, you are owed 3% of $20,000, which is $600, under the cap. Redeemed in month eleven, 12% of $20,000 would be $2,400, but the cap cuts it to $1,500: 7.5% on your money, not 12%.

The cap starts to bite at the 12% tier once your bid is more than about 8.3 times the opening bid, and at the 3% tier once it is more than 33 times. Every dollar you bid above those points earns nothing extra. That is the arithmetic that should set your ceiling at the auction, not the property's market value.

The redemption year, and the notices that protect the sale

The owner redeems by paying the collector, not you. The collector then notifies you by mail to return your tax sale receipt so the refund can be made (§ 12-51-100). If you sell your position before the year is out, your buyer must give the collector a witnessed and notarised conveyance, and the collector changes the name in the tax sale book (§ 12-51-90(A)).

Between 45 and 20 days before the redemption period ends, the collector must send the owner and any grantee, mortgagee or lessee of record a final certified-mail notice with the amount needed to redeem and the deadline. If it comes back undelivered, that alone is not a reason to withhold or set aside the tax title (§ 12-51-120).

Mortgage lenders have their own protection. A mortgagee that files a list of its mortgages with the tax collector by March 15 is entitled to at least 45 days' written notice before the sale (§ 12-49-1120, § 12-49-1150), and if that notice is not given, the mortgagee's rights, interest and security are not affected by the tax sale or the deed (§ 12-49-1180(A)). A deed that leaves a bank's mortgage in place is not the bargain it looked like.

Mobile homes follow different rules. A mobile or manufactured home that has not been de-titled is personal property for the sale (§ 12-51-40(c)), and personal property normally has no redemption period at all (§ 12-51-110). But the owner or lienholder of a mobile or manufactured home may redeem, and on redemption must also pay the buyer rent of up to one-twelfth of the last year's taxes for each month, never less than $10 a month (§ 12-51-95, § 12-51-96).

If nobody redeems: the tax title and the second year

After the twelve months, the collector executes the tax title. You pay the actual cost of preparing it plus the documentary stamps and recording fees before it is sent to the register of deeds, and delivery there counts as putting you in possession (§ 12-51-130).

The deed is prima facie evidence of good title, and of the regularity of every step before it (§ 12-51-160). Prima facie is not final. An action to recover the land may be brought within two years from the date of the sale, and only after twelve more months beyond the redemption year does the tax deed become incontestable on procedural or other grounds (§ 12-51-90(C), § 12-51-160). In other words, for the first year you hold the deed, a defect in the notices can still take it away.

There is also a way to lose the deal before the deed. If the official in charge discovers, before title passes, that any required step was not properly performed, they may void the sale and refund your money plus only the interest the county actually earned on it, not the 3–12% (§ 12-51-150). A bad mailing address on the owner's notice can turn a 12% year into a bank-deposit year.

The overage belongs to the former owner

If the sale brought in more than the taxes, penalties and costs, the overage is first applied to outstanding municipal tax liens on the property. The rest belongs to the owner of record immediately before the end of the redemption period, payable ninety days after the deed is executed unless someone sues over it in that time; unclaimed for five years, it escheats to the county (§ 12-51-130). The collector must notify the former owner in writing once the deed issues (§ 12-51-60).

If instead the owner redeems, your bid, overage included, comes back to you with the interest above (Charleston County). For the owner's side of the overage, see South Carolina tax sale overage.

Where the list is published, and what happens if nobody bids

The sale must be advertised in a newspaper of general circulation in the county under the heading “Delinquent Tax Sale”, with the delinquent taxpayer's name and the property, for which the county auditor's map-block-parcel number is enough. Real property is advertised once a week for three consecutive weeks before the sale, personal property for two (§ 12-51-40(d)). In practice the county's delinquent tax office also posts the list on its website: Charleston publishes separate real property and mobile home listings.

If no investor outbids it, the parcel goes to the forfeited land commission at the opening bid. The commission is not required to bid on property known or reasonably suspected to be contaminated (§ 12-51-55), and it may refuse to take title if doing so would be against the public interest (§ 12-59-85).

The commission's bids are the second market. Before the deed is made, it may assign its bid for no less than the taxes, penalties and costs; the chairman may take sealed bids for a set period, and anything left is assigned first come, first served, from a list the commission keeps (§ 12-59-80). Charleston runs a sealed-bid silent auction of unsold parcels about a month after the main sale. Once it holds title, the commission may sell on terms of up to ten years secured by a first mortgage (§ 12-59-40), and relatives of a commission member may only buy through an open, competitive process (§ 12-59-150).

The former owner is not always out of the picture. For five years after the redemption period, the owner of property bid in by the commission may sell it with the commission's written approval, paying the taxes due (§ 12-59-50, § 12-59-60).

Six ways people lose money here

1. 1. Calling it a lien and pricing it like one

   You pay the price of a property, all due on sale day, for a one-off 3–12% return (§ 12-51-50, § 12-51-90(B)). There is no certificate and no annual rate.

2. 2. Bidding past the cap

   Interest is capped at the county's opening bid (§ 12-51-90(B)). Above roughly 8.3 times that bid, extra dollars earn nothing even at 12%.

3. 3. Counting on 12%

   Owners who redeem early pay 3% or 6%. Model the quarter a redemption is likely in, not the best case.

4. 4. Not checking the notices

   A missed step lets the official void the sale and refund you only what the county earned (§ 12-51-150); an unnotified mortgagee keeps its mortgage (§ 12-49-1180).

5. 5. Treating the deed as final on day one

   The deed is only prima facie good title; it becomes incontestable two years after the sale (§ 12-51-90(C), § 12-51-160).

6. 6. Assuming the legislature will not move the date

   In 2020, Act No. 174 added twelve months to the redemption period of every 2019 sale still open. It has happened once.
