Lake County, home to Crown Point and some 0.50 million Hoosiers, uses Indiana's standardized property tax structure: gross assessed value, a homestead standard deduction of $48,000, a supplemental deduction of 40% on what remains, and a constitutional 1% cap — the "circuit breaker" — on total tax for owner-occupied homes. This guide walks through all of it, plus the new 2026 Supplemental Homestead Credit introduced under SEA 1.

How the bill is built

Indiana calculates property tax in a very different way from most states. Start with your home's gross assessed value (AV), subtract the $48,000 Homestead Standard Deduction, then subtract 40% of what's left as the Supplemental Homestead Deduction. What remains is your net AV, and that is multiplied by your tax district's combined rate (per $100 AV). The result is then capped at 1% of your gross AV under Indiana's circuit breaker — meaning most homesteads in high-rate districts effectively pay 1% flat.

Important for 2026: Under Senate Enrolled Act 1 (2025), every homestead also receives a new Supplemental Homestead Credit equal to 10% of your tax liability, up to $300 per year. This is applied automatically — no form required — starting with bills due in 2026.

Note: Lake County has the highest aggregate property tax collections in Indiana outside of the Indianapolis metro, driven by Gary, Hammond, and East Chicago.
Note: Certified gross tax rates in the Hammond and Gary school districts are among the highest in Indiana, but the 1% circuit breaker cap keeps homestead bills moderate.
Note: Many Lake County homeowners have their full gross tax reduced by the circuit breaker cap — a larger share than in most other Indiana counties.

Deductions and credits for 2026

Homestead Standard + Supplemental Deductions

Indiana's two-part homestead deduction is the single most valuable tax reduction available to homeowners. For 2026, the Standard Deduction is $48,000 off your gross AV, and the Supplemental Deduction is 40% of what remains after the Standard is applied. Together these typically shield about 65% of a typical home's AV from taxation before any rate is even applied.

File Form HC10 (Homestead Property Tax Deduction) with the Lake County Assessor by December 31 of the year preceding the tax year. Many closings handle this automatically — verify on your next tax bill that "Homestead Standard Deduction" appears as a line item.

Phase-in schedule: Under SEA 1, the Standard Deduction drops to $40,000 in 2027 and phases out entirely by 2030, while the Supplemental percentage rises from 40% (2026) to 66.7% by 2031. The net effect is roughly revenue-neutral for most homeowners — just a different calculation path.

The 1% Circuit Breaker Cap

Indiana's constitution caps homestead property tax at 1% of gross assessed value. If your calculated tax would exceed that amount (which is common in high-rate districts like Hammond, Gary, and South Bend), the bill is reduced to the cap. Non-homestead residential property is capped at 2%, and commercial at 3%.

Supplemental Homestead Credit (new in 2026)

Under SEA 1, qualifying homesteads receive a credit equal to the lesser of 10% of your tax liability or $300. This is applied automatically to your bill — no application needed.

Over 65 Credit

Replacing the old Over 65 Deduction, this new credit provides up to $150 directly off your tax bill. Income limit is $60,000 single / $70,000 joint. File Form 43708 with your county auditor by January 15 of the tax year.

100% Disabled Veteran Exemption

Veterans with a 100% service-connected disability qualify for a full exemption on their primary residence. Partial disability deductions vary by rating.

Appealing your assessment

If you believe Crown Point-area assessed values on your property are too high, you can file Form 130 (Taxpayer's Notice to Initiate an Appeal) with your township assessor within 45 days of receiving your Form 11 assessment notice, which typically arrives in the spring. Most appeals are resolved informally with the assessor; unresolved disputes go to the county Property Tax Assessment Board of Appeals (PTABOA).

Cities and towns in Lake County

Lake County contains 19 incorporated municipalities, ranging from Crown Point to the smallest village. Search volume for property tax is often city-specific, so here is the complete list — with population from the 2020 US Census, rounded to the nearest 100.

About city-level property tax rates: The rate breakdown and calculator on this page reflect the Crown Point tax district. Other cities in Lake County may pay into different school districts, city rates, and special districts — so their combined rates can differ, sometimes substantially. Always verify the specific rates for your address with the Lake County Assessor before relying on any estimate.

Frequently asked questions

When are Lake County property taxes due?

Indiana property tax bills are paid in two installments: May 10 and November 10 of each year. Payments received after these dates begin accruing a 5% penalty that grows to 10% after 30 days.

How does the Indiana 1% circuit breaker cap actually work?

Indiana's constitution caps homestead property tax at 1% of your gross assessed value. If your calculated tax (after deductions) would exceed 1% of gross AV, the excess is automatically "forgiven" — you never pay more than 1%. In Lake, Marion, and St. Joseph counties, a large share of homesteads hit this cap.

Do I have to apply for the Supplemental Homestead Credit?

No. If your property already has the Homestead Standard Deduction on file, the Supplemental Homestead Credit is applied automatically starting with your 2026 bill. Check that it appears on your bill under "Credits."

When does my homestead deduction need to be filed by?

File Form HC10 with your county auditor by December 31 of the assessment year. Many real-estate closings handle this paperwork — verify on your first full-year tax bill that the deduction appears.

About Lake County

Beyond the property tax — a few things you might not know about the place.

Weird fact
Humorist Jean Shepherd grew up in Hammond, and his semi-autobiographical radio stories became the basis for the 1983 film A Christmas Story. The fictional town of "Hohman" in the movie is Hammond, and the Warren G. Harding Elementary School Ralphie attends is based on Shepherd's actual school. A leg-lamp sculpture stands in downtown Hammond as a tribute.
Hometown hero
Michael Jackson
The King of Pop was born in Gary in 1958, the seventh of nine Jackson children. The family's two-bedroom house at 2300 Jackson Street still stands as a memorial visited by fans from around the world.
Biggest annual event
Pierogi Fest
Held the last weekend of July in downtown Whiting, this celebration of Eastern European heritage draws around 300,000 visitors to 119th Street. It is the third-largest festival in Indiana and features a wacky Polka Parade led by grandmothers in housecoats and a lawnmower brigade in socks and sandals.

About this site's data and estimates. The Property Tax Almanac is an independent editorial reference. It is not affiliated with any government agency, tax assessor, or tax preparation service. The calculators and data on this site are informational and are not a substitute for advice from a qualified tax professional, attorney, or your official county assessor or appraisal district.

Accuracy, sources, and scope. Tax rate data is compiled from publicly available sources — including the Texas Comptroller of Public Accounts, the Indiana Department of Local Government Finance, individual county appraisal and assessor offices, and the US Census Bureau — and is believed to be accurate as of the "revised" date shown on each page. Rates change annually (and sometimes mid-year) through local budget adoptions, legislative action, and voter-approved measures. Rates displayed reflect the primary tax district of the county seat; rates in other cities, school districts, Municipal Utility Districts (MUDs), Emergency Services Districts (ESDs), and special taxing units within the same county may be meaningfully higher or lower. Census population figures are from the 2020 Decennial Census and are rounded to the nearest 100.

How to use these estimates. The calculator produces a rough estimate based on the county seat's combined rate, statutory deductions and exemptions available statewide, and the value you enter. Your actual bill depends on your specific parcel's assessed or appraised value, the exact taxing entities covering your address, any local-option exemptions you qualify for, any assessment caps or circuit-breaker protections, and any appeal or protest outcomes. For an authoritative figure, consult your county appraisal district (Texas) or county assessor and auditor (Indiana). The contact information for the primary authority in each county is listed at the top of that county's page.
