How Mason County sells delinquent taxes

Tax certificate sale (lien)

Mason County Treasurer and Collector
Frequency

Sale list
Mason County trustee auction results and assignable certificate list (ILTaxSale.com)
When it runs
The Treasurer's property tax calendar for 2025 taxes payable in 2026 lists the sale only as "Tax Sale: (date not set yet)", so no 2026 date was posted as of late July 2026. The same calendar sets the second installment due date at September 8, 2026, and the annual sale follows the second installment under the collector's application for judgment and order of sale. An archived Illinois tax sale schedule from the county's sale software vendor lists Mason County on October 29, 2020 at 1:00 PM, which points to a fall sale. Confirm the current date with the Treasurer's office at 309-543-3359, option 3.
Registration and deposit

Mason County does not post a tax sale registration packet, deposit amount, or bidder deadline online. Tax buyers register with the County Collector ahead of the annual sale, and the vendor page for the county's sale software quotes 35 ILCS 200/21-205: "All bidders are required to personally attend the sale." Mason County appears on that vendor's list of Illinois counties using the R.A.M.S. bid collection system, under which each registered buyer brings a file of penalty percentage bids to the sale on a USB drive and every parcel is awarded to the lowest bid, with ties broken at random. Request the current registration form, deposit, and deadline from the Treasurer's office at 309-543-3359, option 3 or treasurer@masoncountyil.gov.

Sale format and venue
The annual tax sale is run by the Mason County Treasurer and Collector at the courthouse in Havana. The county website carries a tax sale line inside its property tax calendar but publishes no sale date, no registration packet, and no delinquent list, so the statutory newspaper notice and a call to the Treasurer are the practical sources. No online bidding platform is confirmed for this county, verify with the office before planning a remote bid. Joseph E. Meyer & Associates serves as delinquent tax agent, or county trustee, for 94 of 102 Illinois counties, and its ILTaxSale.com Mason County page covers the separate trustee program for parcels no tax buyer purchased at the county sale, sold verbally or by sealed bid. Mason County trustee sealed-bid sales ran July 12, 2024, July 18, 2025, and July 17, 2026, and that mid-July trustee event is a different sale from the county's annual tax sale. The trustee also offers a Mason County list of assignable tax lien certificates for a $25 fee. Parcel level tax and payment research is free at masonil.devnetwedge.com. In person, no online bidding platform confirmed

When it runs

That notice runs once a week for 3 consecutive weeks, starting no more than 45 days and ending no less than 7 days before the auction. Read the notice for each parcel; there is no statewide platform or standing bidder registration.

Sale format and venue
Bidding opens at the tax deed judgment amount plus 0.75 percent per month since judgment, plus publication and selling officer costs. The petitioning certificate holder is entered as a credit bidder at that minimum. Surplus above the minimum goes to the county treasurer for the former owner to claim.

Over-the-counter (leftover) purchases

Certificates nobody bids on at the annual sale are forfeited to the county as trustee for the taxing districts. The county may then assign a forfeited certificate to any party or sell property it has acquired, which many counties handle through a delinquent tax agent rather than a public counter. Counties may also offer county-held certificates at a scavenger sale with a minimum bid of $250, or half the tax when total liability is under $500. Ask the county collector and the county clerk which program the county runs and who may buy.

Illinois rules

Max interest rate
9% per redemption period maximum, bid down at auction
Minimum return
No statutory minimum return; what you earn is set by the penalty rate at the sale
Redemption
Property sold at an Illinois tax sale may be redeemed at any time before the redemption period expires. Public Act 104-0553 set the standard period at 3 years from the date of sale for tax certificates issued on or after July 10, 2026. Certificates issued between January 1, 2024 and July 9, 2026 run on the earlier 2.5 year (30 month) track, and on that track the certificate holder could file a written notice with the county clerk extending redemption to a date no later than 3 years from the sale. A short 1 year period applies when the parcel was, on the date of sale, vacant non-farm property, commercial or industrial property, or improved with a structure holding 7 or more residential units. Certificates the county holds or assigns as trustee run on their own schedule under Section 21-385, and an assignee must file notice within 60 days of assignment setting a redemption deadline no later than 3 years from the assignment.
Deed deposit
Illinois does not fix a statutory deposit percentage. Deposit and payment terms are set in the court's order authorizing the auction and by the selling officer, so read the notice of tax deed auction for each sale. A purchaser who fails to complete the sale forfeits any deposit already made to the county surplus equity fund, and the court orders a new auction of the property.
Surplus proceeds
Any amount by which the winning bid exceeds the minimum bid is surplus. Within 30 days after the court confirms the sale the selling officer deposits the surplus with the county treasurer, who notifies everyone who received the Section 22-10 take notice that the owner at the time of the sale may file a claim for it. A county running its own tax deed auction deposits surplus with the treasurer within 30 days of the sale and notifies interested parties within 60 days. Separately, a previous owner who lost equity through a tax deed can claim an award from the county surplus equity fund, capped at the value of the property when the deed issued less mortgages, liens, and the taxes the purchaser paid.
Governing statute
35 ILCS 200, Articles 21 and 22

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
