Iowa vs Illinois
Same underlying data as the individual state pages, side by side. Statutory rates and redemption windows only — always confirm against the county's own auction notice before bidding.
| | Iowa | Illinois |
|---|---|---|
| Sale type | Tax lien certificate | Tax lien certificate |
| Rate / penalty | 24% flat, no bid-down (rotational) | Up to 18% per 6-month period, bid down |
| Redemption | 1 year 9 months | 2–3 years |
Both states run the same kind of sale — tax lien certificate — so the real difference between them comes down to rate and redemption, not the underlying mechanism.
Redemption windows differ: Iowa gives owners 1 year 9 months, Illinois gives 2–3 years — the state with the shorter window resolves faster, for better or worse depending on what you're optimizing for.
Iowa fixes its tax lien interest rate by statute at 24% annually, with no bid-down auction — the rate doesn't change regardless of demand for the certificate. Owners have roughly one year and nine months to redeem before the certificate holder can move toward a deed.
