The short answer
2 years for a residence homestead, agricultural-use land, or a mineral interest; 180 days for all other property
How the clock works
The redemption clock runs from the date the purchaser's deed is filed for record, not from the sale date. Property that was the owner's residence homestead or was land designated for agricultural use when the suit or the warrant application was filed, and any mineral interest, may be redeemed on or before the second anniversary of that filing. Every other property may be redeemed only through the 180th day after the deed is filed. When a parcel is struck off to a taxing unit instead, the period runs from the date the taxing unit's deed is filed for record. The former owner has no right to use, possess, or collect rent from the property while the redemption right runs, and the right of redemption cannot be sold or transferred: any instrument purporting to transfer it is void.
Who can redeem
The owner of the property sold. A person asserting ownership may redeem if that person held title, or was in possession personally or through a tenant, either when the foreclosure suit was filed or when the property was sold, and a defect in the chain of title does not defeat the offer. If the owner cannot find the purchaser, the purchaser does not live in the county, the two cannot agree on the amount, or the purchaser refuses a quitclaim deed, the owner may pay the county assessor-collector under a sworn affidavit instead.
What the owner pays to redeem
The amount the purchaser bid, plus the deed recording fee, plus the taxes, penalties, interest, and costs the purchaser paid on the property, plus a redemption premium. On homestead, agricultural-use, and mineral-interest property the premium is 25 percent of that aggregate total in the first year of the redemption period and 50 percent in the second. On all other property the premium may not exceed 25 percent. Recoverable costs are defined by statute and cover property insurance, repairs required by a local ordinance, building code, or an existing lease, discharging a municipal health or safety lien, property owners association dues, and impact or standby fees. The purchaser must itemize those costs in writing within 10 days of a written request, and only itemized amounts count toward redemption.
How your interest accrues
The premium is a flat statutory add-on to the amount paid at the sale, not a rate that accrues over time. A redemption on the first day pays the same 25 percent as one on the last day of the window, so an early redemption produces a very high annualized return. The clock runs from the date the purchaser deed is filed for record rather than from the sale date.
Why some certificates are bid to zero
There is no interest bid-down in Texas, because no certificate is auctioned. Bidders compete on price, and the buyer return is the statutory redemption premium under Section 34.21: 25 percent of the amount paid if the owner redeems in the first year, and 50 percent if a residence homestead, agricultural-use land, or a mineral interest is redeemed in the second year. Property outside those categories has a 180 day window and pays the 25 percent premium.
What happens when it ends
Once a tax becomes delinquent, a taxing unit may sue to foreclose the lien securing it. If the court renders judgment for foreclosure, it orders the property sold in satisfaction of the judgment, and the district clerk issues an order of sale to an officer authorized to conduct execution sales. An order of sale must be returned unexecuted if it is not executed before the 181st day after it is issued. If the owner pays the judgment before the sale, the taxing unit releases its lien.
A redeemed certificate, plus your accrued interest, is what makes the wait profitable; see how redemption periods work across states. An unredeemed certificate is instead your path to the property through a tax deed sale, which still does not convey marketable title on its own, so budget for a quiet title action.
