How do tax lien certificates earn a return?

You pay the delinquent taxes and fees. If the owner redeems, you are repaid plus statutory interest or a redemption penalty, depending on the state's rules.

Is a premium bid refunded?

Often not. Many states do not return the premium bid above the lien amount when the owner redeems, so check local rules before assuming it is repaid. The calculator lets you set whether it is refunded.

What if the owner never redeems?

The outcome can shift to a foreclosure or tax-deed process with separate costs and timelines. The calculator assumes redemption occurs on schedule.

Does every state use the same tax lien return structure?

No. Some states pay annual interest and others charge a flat penalty, so verify the applicable state and local rules before relying on a return.

Frequently Asked Questions

How a tax lien earns

Statutory interest: Some states pay a set annual rate that accrues for as long as the lien is held before redemption.
Flat penalty: Others charge a fixed penalty instead, so redeeming early produces a much higher annualized return than redeeming late.
Lien position: Tax liens usually sit ahead of mortgages, but title and other liens still affect what the property is worth if redemption fails.
Redemption assumption: The calculator assumes the owner redeems. If not, the outcome shifts to a foreclosure or tax-deed process with its own costs and timeline.
