Tax lien interest rates by state

Tax Sale Atlas holds a top statutory rate for 14 of the 15 lien and hybrid states it has mapped, from 9% to 24%. The remaining lien state publishes no single statewide figure, and deed states pay no investor interest at all. Checked Aug 28, 2026.

The maximum interest a tax lien certificate can earn, and how that rate is set, varies by state. Some states fix the rate by statute, others let bidders bid it down at the sale, and a few leave it to county law. This table lists the top rate, the mechanism, and any statutory minimum, each cited to the source.

Most of these rates are a statutory ceiling, but not all. Where the mechanism reads "Set by county law" the statute sets only a default and counties may go above it, so the figure is the highest confirmed county rate rather than a cap. In bid-down states the rate you earn is set at the auction and is often well below the headline. Confirm the figure with the county before you bid, and see realistic tax lien returns for why the effective yield differs from the headline rate.
