How mosques lose their buildings over property tax, and how to keep yours

Updated October 21, 2026 · 18 min read · Ihsan Standard

In September 2025, a suburban Chicago county sold the property taxes on a masjid’s 13-acre site. The land had been billed as fully taxable for four years while the community built on it, around $43,000 in all, and every bill went to the address of one of the community’s other masjids. The 2024 bill went unpaid, and the county offered it at its annual tax sale, where an outside buyer purchased it.^[21] The community has since reported a settlement, and the county now lists the land as exempt. It took a great deal of worry to fix a problem that a once-a-year check would have caught.

Cases like this happen more often than most boards realize, and the people involved are rarely careless. Most masjid boards are volunteers who assume, reasonably, that a nonprofit house of worship doesn’t pay property tax. Often that assumption is right. When it isn’t, the system that collects the tax runs on deadlines and mailed notices, and it will sell the debt whether or not anyone at the masjid has read the mail.

Why a tax-exempt mosque can still owe property tax

The IRS decides whether a masjid is exempt from federal income tax. It has no say over property tax, which is set by states and collected by counties and cities. Each state writes its own rules for religious property, and nearly all of them make the organization ask for the exemption. New York’s Attorney General tells nonprofits directly that property tax exemptions “are NOT automatic,” even for organizations that are exempt from federal and state income tax.^[1] In Florida, the owner must apply to the county property appraiser by March 1, and missing the deadline waives the exemption for that year.^[2] In Illinois, a religious organization files form PTAX-300-R with the county board of review, which recommends a decision to the Illinois Department of Revenue.^[3]

Three conditions come up in almost every state. The organization has to own the property, the property has to be used for the exempt purpose, and someone has to file the paperwork. When any one of these slips, the building goes back on the tax roll.

The exemption doesn’t come with the building

Many communities buy a church, a school or an office and assume the old exemption continues. It usually doesn’t. Texas law says an exemption applies “until it changes ownership.”^[4] California gives a church that buys property a short window to file its own claim.^[5] Illinois requires the new owner to tell the county in writing within 90 days of any change in owner or use, and if nobody does, the county can later bill the years the property wrongly sat as exempt.^[6] A building that was exempt for decades under its previous owner can be fully taxable the day your community takes the keys.

Property in a person’s name

In the early years many communities buy property in a founder’s or imam’s name because the nonprofit doesn’t exist yet, or because a bank wants a personal borrower. Religious exemptions generally require the religious organization to be the owner. Texas’s statute uses the phrase “owned by the religious organization” for each kind of exempt religious property.^[7] A masjid held in a person’s name is billed like any other property, and the bills go to that person. If they move, fall ill or die, the notices stop reaching anyone who knows what they mean.

Land you haven’t built on yet

Exemptions are usually tied to use. A parcel bought for a future masjid, parking lot or school may be taxable until it is actually used for worship or another exempt purpose, and construction can take years. The Illinois case above is exactly this: four years of bills on land under construction. Budget for those taxes from the day you buy, and ask the county when you can apply for the exemption.

How an unpaid bill becomes a lost building

The details vary by state, but the path is similar almost everywhere:

The bill goes unpaid. Penalties and interest start, often at high rates.
The county publishes a delinquent list, frequently only in a local newspaper, and mails notices to the address on file.
The county sells the debt. In tax-lien states an investor buys a lien or certificate and collects interest or penalties when the owner pays. In other states the government sues and the property itself is sold.
A redemption period starts. The owner can still pay everything owed, plus interest and costs, and keep the property.
If nobody redeems in time, the buyer asks for a deed. The building now belongs to someone else, and the congregation may have to leave.

Buyers at tax sales are usually investors. Some are individuals and some are large funds. They are doing something the law allows, and many of them make their money from the interest when owners pay up. But a buyer has every right to take the deed when the redemption period runs out, and a masjid that hasn’t been watching the mail can lose its building to a debt that was small at the start.

What the rules look like in some key states

These are short summaries of how each state works, checked against the statutes in October 2026. Laws change. Treat this as a map, and confirm the details with your county or a lawyer.

State	What happens when taxes go unpaid
Illinois	Every county holds an annual tax sale of delinquent taxes. Buyers get a certificate of purchase, not the building. For certificates sold on or after July 10, 2026, the owner generally has three years to redeem, but only one year for vacant non-farm, commercial or industrial property. After that the buyer can go to court, and the process can end with the property being sold out from under the owner.^[8]
New York City	Unpaid property tax, water and sewer charges become liens. After notices at 90, 60, 30 and 10 days, unresolved liens are sold to a city-created trust, which charges interest and typically forecloses if the debt isn’t resolved within about a year.^[9] Since 2020, the property-tax part of a lien on a nonprofit that recently held certain exemptions can’t be sold, but water and sewer debt still can.^[10]
California	Taxes unpaid on July 1 become “tax-defaulted.” After five years (three for nonresidential commercial property) the tax collector gains the power to sell.^[11] Owners can enter a five-year payment plan before that point. California has separate religious, church and welfare exemptions with different forms and filing schedules.^[5]
Texas	Religious organizations apply to the county appraisal district. Once taxes are delinquent, taxing units can sue, and the property is sold at a public sale. A non-homestead property, which includes a mosque, has only 180 days after the buyer’s deed is recorded to redeem.^[12]
Michigan	Unpaid taxes are returned delinquent the March after they are levied, forfeit to the county treasurer the following March, and are foreclosed a year after that. For 2024 taxes, the last day to redeem would be March 31, 2027.^[13]
Florida	Taxes become delinquent on April 1 and the county sells tax certificates. Once two years have passed since April 1 of the year a certificate was issued, its holder can apply for a tax deed. Exemptions require a yearly application.^[14]^[2]
Maryland	The county must sell property with taxes in arrears at its tax sale. The certificate holder can move to foreclose the right of redemption after six months.^[15]

The ways it actually happens

When we look at cases, the cause is rarely a community that refuses to pay. It is almost always one of these:

The exemption was never filed after a purchase, so the building has been taxable from the start.
The property, or one of several parcels, is in a person’s name.
Tax bills go to an old address: a former treasurer’s home, a closed office, another masjid, or a P.O. box nobody checks.
A second parcel was forgotten. The prayer hall is exempt, but the parking lot, the house next door or the empty lot behind it isn’t.
Land bought for a future building is taxable during the years of fundraising and construction.
An exemption that has to be renewed every year lapsed when the person who filed it left the board.
Water, sewer or other city charges went unpaid. In some cities these can be sold just like property tax.
The masjid rents its space and its landlord fell behind on taxes. The lease is at risk even though the masjid did nothing wrong.

Cases from houses of worship

Masjid Al-Faysal, the Bronx

A West African congregation bought 3400 Third Avenue in the Bronx in 2002. The tax office had a wrong mailing address for the mosque, and when it searched for the owner it looked for a person named “Mr. Masjid Al-Faysal.”^[16] The city’s tax lien had been sold to a lien trust, the trust foreclosed, and the building was auctioned in 2008. The congregation went to court. In May 2009 the Appellate Division vacated the judgment and dismissed the case because the mosque, as a corporation, had never been properly served.^[17] They won the building back, but only after more than a year of litigation.

Taylor Road Synagogue, Cleveland Heights

The congregation had deeded its building to a company and leased it back. The company left millions in property tax unpaid over many years, the county foreclosed, and the state took the property in 2023.^[18] The building was later transferred to a new owner and the congregation was evicted. Once the deed left the congregation’s hands, it had no say in whether the taxes were paid.

Churches and a Hindu temple in Schenectady, New York

Between 2004 and 2009 the city sold liens on several churches and a Hindu temple whose exemptions had been removed. It took a 2013 state law to restore their exemptions, and the law was written to undo those sales.^[19]

New York City’s lien-sale lists

Before the 2020 reform, New York City’s lien-sale lists regularly included nonprofits and houses of worship. One Brooklyn church had a lien sold on debt it didn’t legally owe, and legal aid had to get it wiped out. The City Council passed the 2020 protections largely because of cases like these.^[20]

What the community loses

A lost building is the obvious harm, but it is rarely the only one. Communities spend savings and new donations on penalties, interest and lawyers instead of programs. Jumu‘ah and classes move to rented halls or stop altogether. Donors who gave to build the masjid wonder what happened to their money, and members who suspected something was wrong feel ignored. Even when the building is saved, trust in the board can take years to recover.

For Muslims this is also a question of amānah. The masjid and the money given for it are a trust held by the board for the whole community: “Allah commands you to render trusts to whom they are due” (Qur’an 4:58). Many masjids are endowed as waqf, property meant to serve the community permanently. Keeping the deed in order and the taxes current is part of fulfilling that trust, as ordinary as paying the electricity bill.

A yearly checklist for masjid boards

Put this on the agenda once a year, assign it to one named person, and record the result in the minutes.

List every parcel the masjid owns or controls: the prayer hall, parking, houses, vacant lots, cemetery plots and any land held for the future.
Look up each parcel on the county assessor’s or appraiser’s website and confirm the owner name is exactly the masjid’s nonprofit.
Confirm each parcel shows an exemption. If one is taxable on purpose, such as a rental house, confirm its taxes are paid.
Look up each parcel on the county treasurer’s or tax collector’s website for unpaid, delinquent or sold taxes.
Check the mailing address the county uses for bills and notices, and change it to an address someone actually reads.
Find out whether your exemption needs renewing, how often, and when the deadline is. Put the deadline in a shared calendar.
If you bought, sold or changed the use of any property this year, file the notices or new applications your state requires.
Check water, sewer and other municipal bills, especially in cities that sell those debts.
If you rent, ask your landlord to confirm the property taxes are current, and make sure the lease is in the masjid’s name.
Keep copies of exemption approvals, deeds and tax receipts where the next board can find them.

If a notice has already arrived

Don’t wait for the next board meeting. Call the county treasurer or tax collector the same week and ask exactly what is owed, whether anything has been sold, and what the deadlines are.
Ask about payment plans. Many counties have them, and some stop a sale while the plan is current. California, for example, offers a five-year plan for tax-defaulted property.
If you think the property should have been exempt, ask how to apply, whether past years can be corrected, and whether your state treats the exemption as a defense to the sale.
In New York City, contact the Department of Finance’s nonprofit ombudsperson and check the nonprofit lien-sale page.^[22]
If taxes have been sold, find out the redemption deadline in writing, and talk to a property or tax lawyer. Redemption periods can be as short as six months.
Tell the community what happened and what the board is doing. Members are far more forgiving of a problem that is being handled openly than of one they discover later.

How Ihsan Standard helps

Ihsan Standard is an independent standard for Muslim institutions. Property-tax standing is one of the governance standards we check for every mosque in our listings.

Every week we compare our listed mosques with public county and city property records in 26 counties, cities and states: who owns each parcel, whether it carries an exemption, where bills are mailed, and, where the county publishes it, whether taxes are delinquent, sold or on a tax-sale list.
A person checks every lead against the official record before anything else happens. Automated matches are never published on their own.
Where we have a way to reach the mosque, we contact it privately, explain what the record shows, and point to payment plans and help.
Each mosque’s Ihsan page shows its governance standards, including property-tax standing, so members can see where things stand and ask the board kind, specific questions.
We offer a free property check, and a full Ihsan Standard audit of the masjid’s finances, governance, bylaws and property, carried out under a mutual NDA.

Frequently asked questions

Is a mosque automatically exempt from property tax?

No. Federal tax-exempt status under 501(c)(3) covers income tax. Property tax is set by states and counties, and in most places a religious organization has to apply for the exemption, own the property, and use it for worship or another qualifying purpose. New York's Attorney General puts it plainly: property tax exemptions are not automatic, even for organizations exempt from federal and state income tax.

We bought a church building that was already exempt. Do we need to apply?

Almost always, yes. In Texas the exemption ends when the property changes ownership. Illinois requires the new owner to notify the county within 90 days of a change in owner or use, and California gives a church that buys property a short window to file its own claim. Assume the old exemption left with the old owner until the county confirms otherwise.

What is a tax sale or tax lien sale?

When property tax goes unpaid, most states let the county sell the debt. Depending on the state, an investor buys a tax lien or certificate (and earns interest or penalties when the owner pays), or the property itself is sold after a court case. If the owner doesn't redeem within the legal period, the buyer can apply for a deed to the building.

How long does a mosque have to redeem after a tax sale?

It depends on the state and the type of property, and the periods can be short. In Illinois, certificates sold from July 10, 2026 generally carry three years, but vacant or commercial property has one year. In Texas a non-homestead property has 180 days after the buyer's deed is recorded. Call the county treasurer or clerk the day you learn of a sale.

Can a mosque lose its building over a water bill?

In some cities, yes. New York City can sell liens for unpaid water and sewer charges, and its 2020 protection for nonprofits covers only the property-tax part of a lien, so a congregation's water and sewer debt can still be sold.

Our property is in the imam's name. Is that a problem?

It usually is. Religious exemptions generally require the property to be owned by the religious organization, so a building titled to a person is billed as taxable. If that person moves away or dies, tax notices can stop reaching anyone at the masjid. Transfer title to the masjid's nonprofit and then apply for the exemption.

How does Ihsan Standard help with property tax?

Ihsan Standard checks public county records for the mosques in its listings every week, across the counties and cities where most US mosques are. It reviews anything it finds against the official record, reaches out to the mosque where it can, offers a free property check, and offers a full Ihsan Standard audit of the masjid's finances, governance and property under a mutual NDA.
