If you own a home in Morris County, you've been feeling the sting of the SALT cap for years. Since 2017, the federal deduction for state and local taxes — including property taxes — was capped at just $10,000. In a state where the average property tax bill runs well above that number, the cap effectively punished New Jersey homeowners every tax season. That's now changed. The SALT deduction cap has been raised to $40,000, and the impact for homeowners in high-tax areas like Morris County could be significant.
Why This Matters in Morris County
Morris County has some of the highest property taxes in the entire country. In Mountain Lakes, the average annual tax bill is north of $23,000. In Boonton Township, it's around $13,200. Even in Boonton proper, you're looking at roughly $12,200 per year. Under the old $10,000 cap, homeowners in all of those towns were losing thousands of dollars in federal deductions every year — money they used to be able to write off before the cap took effect.
With the cap now at $40,000, most Morris County homeowners will be able to deduct their full property tax bill again — plus a portion of their state income tax — without hitting the ceiling. For a household in Mountain Lakes paying $23,000 in property taxes and another $10,000 to $15,000 in state income tax, that's a potential swing of tens of thousands of dollars in additional deductions compared to the old limit.
There's an important caveat: this benefit only applies if you itemize your deductions rather than taking the standard deduction. Experts estimate that roughly 90% of filers nationwide will still choose the standard deduction. But in high-tax areas like Morris County, where property taxes alone often exceed $10,000, a much larger share of homeowners are likely to benefit from itemizing — and the new SALT cap makes that math significantly more favorable.
New Jersey's Property Tax Relief Programs Are Stacking Up Too
The SALT cap change is happening at the same time New Jersey is expanding its own property tax relief. The state's FY2026 budget includes nearly $4.3 billion in direct property tax relief — a record. Here's what's on the table right now.
The Stay NJ program is now dedicating $600 million to reduce property taxes for homeowners aged 65 and older. Qualifying seniors with household incomes under $500,000 can receive a credit for up to half their property tax bill, capped at $6,500. In a county where senior homeowners are often sitting on paid-off houses but getting crushed by annual tax bills, this is a meaningful lifeline.
The ANCHOR program is continuing with $2.4 billion in funding. Homeowners earning up to $150,000 can receive up to $1,500 in relief, and those earning between $150,000 and $250,000 can receive up to $1,000. Renters are also eligible for a benefit. It's not a massive check, but combined with the SALT cap increase, the cumulative relief is real.
And the Senior Freeze program — which reimburses eligible seniors and disabled residents for property tax increases — is funded at $239 million, covering more than 235,000 taxpayers statewide.
How This Affects the Housing Market
The financial picture for owning a home in Morris County just got meaningfully better. When the total cost of ownership drops — through higher federal deductions, state tax credits, and relief programs — it changes the calculus for both buyers and sellers.
For buyers, the higher SALT cap makes homeownership in high-tax towns more financially viable than it's been in nearly a decade. A Mountain Lakes home with a $23,000 tax bill looks very different when you can deduct the full amount versus only $10,000. That changes what buyers can afford and how they evaluate properties across different price points and towns.
For sellers, this is also positive news. Buyers who were previously hesitant about New Jersey's tax burden may be more willing to commit now that the federal deduction is back in play. That expanded buyer pool — combined with the ongoing housing shortage in NJ (the state is estimated to be short over 200,000 units) — supports continued demand and price stability in Morris County.
And for current homeowners who were thinking about relocating to a lower-tax state, the math has shifted. The combination of a $40,000 SALT cap, Stay NJ credits, and ANCHOR benefits could reduce the effective tax burden enough to make staying in place a stronger financial decision than it was a year ago.
What You Should Do Now
If you haven't already, talk to your tax professional about whether itemizing your 2026 return makes sense under the new cap. For most Morris County homeowners, the answer is likely yes — but it depends on your full financial picture. Make sure you're also checking eligibility for ANCHOR and, if applicable, Stay NJ or Senior Freeze. These programs require applications, and deadlines matter.
And if you're thinking about buying or selling in this environment, understand that tax policy is one piece of a much larger puzzle. Interest rates, inventory levels, local pricing trends, and the condition of the home all factor into the decision. The SALT cap increase is great news for the market — but the best move for you still depends on your individual situation.
