Say you're choosing between a home at The Bridgewater Club, which has a Carmel mailing address but a Westfield tax bill, and a similar home a few miles south inside Carmel. Which one costs more in property tax each year? The county rate sheet seems to settle it fast. Westfield's rate is higher. For a Bridgewater-level home, though, that rate barely touches the regular bill. Indiana's homestead cap absorbs most of the difference. The part of the bill the cap can't reach is the school referendum, and both school districts put new referendums on the ballot on November 3, 2026.
Two Rates and One Ceiling
The Department of Local Government Finance publishes a district rate for every taxing district in Hamilton County. The county's 2026 sheet lists Westfield Town at 2.3448 per $100 of net assessed value and Carmel City at 2.0167. Parcels inside Westfield city limits, which is where The Bridgewater Club's Westfield taxes and utilities come from, fall in the Westfield Town district. That puts the Westfield rate about a third of a point higher than Carmel's. On a large home, that would look like well over a thousand dollars a year.
That comparison skips the circuit breaker. Under Indiana's 2008 tax caps, a homestead's total bill, not counting referendums, can't go above 1% of the home's gross assessed value. Once a bill reaches that 1% line, a higher rate doesn't make the bill any bigger. It only means the local units of government lose more revenue to the cap. Current in Carmel reported this fall that nearly 38% of Carmel properties have already hit the cap.
The cap matters more as values go up. Indiana's homestead deductions take a fixed dollar amount off the top and then a percentage of what's left. The fixed amount covers a large share of a modest home's value and a small share of an estate home's value. So a bigger share of a high-value home ends up taxable, and that pushes the bill up against the 1% line.
A Worked Example at Bridgewater Prices
Here's a simplified example. Take a homestead with a $900,000 gross assessed value and apply the deductions for taxes payable in 2026.
- Standard deduction. Senate Enrolled Act 1 of 2025 set it at $48,000 for the 2025 assessment, which is the one behind 2026 bills. That leaves $852,000.
- Supplemental deduction. For 2026 bills it's 40%, which takes the net assessed value down to about $511,200.
- Apply each district rate. At Westfield Town's 2.3448, the bill would come to roughly $11,990. At Carmel City's 2.0167, it would be roughly $10,310.
- Apply the cap. One percent of $900,000 is $9,000. Both figures are over that line, so the regular, non-referendum part of the bill stops at the same $9,000 ceiling in both cities.
- Apply the credit. For 2026 bills, each qualifying homestead also gets an automatic credit of 10% of its liability or $300, whichever is less. Referendum taxes don't count toward it. At this value, both homes get the same $300.
The roughly $1,680 gap you'd expect from the rate sheet mostly disappears. This is an illustration, not a forecast of any real bill, because actual bills depend on each parcel's assessed value and eligibility. It shows why the rate sheet answers a different question than the one a buyer is asking. The larger point is that the cap is very likely doing most of the work on bills at this price point.
The Line Item the Cap Doesn't Touch
Referendum taxes are the part that goes on top of the cap. The county's 2026 sheet lists them separately as rates exempt from the circuit breaker. At the moment the two districts are almost the same. Westfield Washington Schools collects 17 cents for operating plus 7.9 cents for debt, 24.9 cents in total. Carmel Clay Schools collects 19 cents for operating plus 5 cents for school safety, 24 cents in total.
That near-tie is what the November 3 ballot could change. The WWS board voted unanimously on June 9, 2026 to put an operating referendum on the ballot. Carmel Clay Schools is asking voters to combine its two current referendums into one eight-year measure.
| Per $100 of assessed value | Westfield Washington Schools | Carmel Clay Schools |
|---|---|---|
| Rate being replaced | 17.0¢ operating | 24.0¢ operating plus safety |
| Ballot maximum | 39.41¢ | 42.74¢ |
| Projected first-year rate | 33.81¢ | 30.39¢ for 2027 |
| Change from today in year one | +16.81¢ | +6.39¢ |
| Change from today at the maximum | +22.41¢ | +18.74¢ |
Sources for the table are the WWS referendum page and Current's reporting on Carmel Clay's 2027 projections.
Coverage has focused on Carmel's ask, which Current described as a rate almost 78% above what residents pay now. But the year-one numbers point the other way. If both measures pass and both districts set rates where they've projected, Westfield's first-year increase is the larger one per $100 of value. Carmel Clay plans to raise its rate in steps until it reaches the maximum about four years later. WWS says it plans to start at 33.81 cents and bring the rate down over time. The board sets the rate each year.
The districts' own estimates are built around much lower values than Bridgewater homes carry. WWS projects a net increase of $147.68 a year for a home assessed at $426,700, after counting the current referendum and the new SEA 1 credits. Carmel Clay projected that the owner of a $482,000 home would pay $15.79 more a month in 2027. Because referendum taxes rise with assessed value and the cap doesn't limit them, a Bridgewater-level bill sees a larger dollar effect than either example. WWS has posted a referendum calculator that uses a parcel's assessed value as of January 1, 2026.
Why the Cap Will Bind Less Each Year
The worked example holds for 2026 bills. SEA 1 changes the math every year after that. The standard deduction falls from $48,000 to $40,000 for the 2026 assessment, then to $30,000, $20,000 and $10,000, and reaches zero with the 2030 assessment. The supplemental deduction goes the other way. It rises from 40% to 46%, 52%, 57% and 62%, and settles at 66.7% for 2031 and later.
For a high-value home, the bigger percentage deduction outweighs the loss of the fixed one. Net assessed value goes down, and the bill based on the rate drops back toward the 1% ceiling. Suppose both cities kept today's district rates through the 2031 schedule. The $900,000 example would then have about $300,000 of net assessed value. That works out to roughly $7,000 in Westfield and $6,000 in Carmel, both below the $9,000 cap. In that scenario the cap no longer evens out the two bills, and the gap between district rates shows up again.
Rates won't stay frozen. Both cities are already planning for smaller revenue. Westfield's proposed 2027 budget sets the city rate at 71.62 cents, compared with 71.63 in 2026, and projects SEA 1 revenue reductions of about $3.5 million in 2027, $6.5 million in 2028 and $11 million in 2029. Carmel's proposed 2027 budget holds its rate at 77.83 cents. Its CFO projected $13 million less revenue next year than the city would have collected without SEA 1. These are proposals, not certified rates. WWS says certification is expected in January.
The first year under the new law shows how small the starting differences can be. Hamilton County Auditor estimates reported by WISH-TV in May 2026 found that the average homeowner paid more in six of the county's 23 taxing districts. The smallest increase was $3.79 in Westfield. Those are district averages, and individual bills vary with assessed value.
The Change After That Moves to Income Tax
The next piece of SEA 1 changes local income tax, not property tax. As first passed, the law started a restructured county income tax with 2028 collections. HEA 1210, passed in 2026, pushed that back a year. Current local income tax ordinances now expire January 1, 2029, and distributions under the new structure start in 2030. Separately, counties can adopt an income tax of up to 0.3% to fund credits for homesteads at the 1% cap. That option has to be adopted by December 31, 2027, and it can't offset referendum taxes. So a buyer comparing Westfield and Carmel today is looking at a property tax picture that will keep changing over the rest of the decade.
Frequently Asked Questions
Does The Bridgewater Club's Carmel mailing address affect the tax bill? No. The mailing address doesn't decide the tax bill. The taxing district does, and The Bridgewater Club gets Westfield taxes, utilities and schools. Each parcel's district is listed on Hamilton County Property Reports. For more on the community itself, see our Bridgewater Club neighborhood guide and our comparison of Bridgewater and Chatham Hills.
When is the fall property tax payment due? WISH reported the fall 2026 deadline as November 10, one week after the referendum vote.
Does the $300 credit lower referendum taxes? No. The pay-2026 homestead credit leaves out referendum taxes when it's calculated.
If a referendum fails, does the old rate continue? That depends on the district. Carmel Clay's operating referendum runs until 2031 and its safety referendum expires in 2027. The new measure would replace both. Each district's materials explain what would happen in its own case.
How the cap, the deductions and the referendum line combine on a specific home is a question about that home's assessed value. It's the kind of math we run with clients before they make an offer on either side of 146th Street. If you own at The Bridgewater Club or in Carmel and want to see where your home's value sits next to these numbers, Team Deck is happy to walk through it with you.
