Tax lien interest rates by state

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 compete by bidding the rate down at the sale. This table lists the ceiling, the mechanism, and any statutory minimum, each cited to the source.

Rates are the statutory ceiling. In bid-down states the rate you actually earn is set at the auction and is often well below the ceiling. Confirm the current figure with the county before you bid, and see realistic tax lien returns for why the effective yield differs from the headline rate.
