A general tax rate of $0.499 per $100. An effective rate of 0.520% — the eighth-lowest of all 53 Monmouth County municipalities. A 2024 average bill of $15,428 on a 1,866-resident borough with median household income of $206,000 and Manasquan-HS-cluster geography. A New Jersey State Police Academy and a Department of Corrections training facility occupying significant non-taxable land within the borough’s 1.06-square-mile footprint. And a development environment with Realistic Development Potential of zero units — the structural foundation that shapes everything about Sea Girt’s tax math.
Sea Girt Borough sits on the southern Monmouth County shore between Spring Lake to the north and Manasquan to the south, completing the prestige southern shore cluster anchored by Spring Lake (Post 7 of this series). Incorporated May 1, 1917 and named after the estate of Commodore Robert F. Stockton, the borough occupies a 1.46-square-mile footprint — 1.06 square miles of land and 0.40 square miles of water (27.12 percent of total area). The 2020 Census recorded 1,866 residents, with the 2025 estimate at 1,874. Mayor Donald Fetzer (R, term ends December 31, 2027) leads a Borough Council form of government, with Administrator Justin Macko and Municipal Clerk Dawn Harriman operating from Borough Hall.
The tax math is structurally distinctive in three ways. First: Sea Girt’s 2025 effective tax rate of 0.520% is the eighth-lowest in Monmouth County, certified by the NJ Treasury 2025 General Tax Rates Table — below every Monmouth municipality except Loch Arbour, Deal, Spring Lake, Allenhurst, Avon-by-the-Sea, Interlaken, and the small Highlands cohort. Second: the 2024 average bill of $15,428 ranks among the highest absolute bills in the entire county, reflecting median home values that placed Sea Girt at 197th on the 2012 Forbes “America’s Most Expensive ZIP Codes” list at a then-median of $1,135,184 — a figure that has since appreciated to a 2026 median sale price near $3.45 million per current market data. Third: the New Jersey State Police Academy (a residential 25-week recruit training facility) and the New Jersey Department of Corrections training facility both occupy substantial state-owned, tax-exempt land within the borough, reducing the ratable base for the year-round 1,866-resident community.
Sea Girt’s 2026 budget cycle faces an unusual structural pressure point: the borough’s Realistic Development Potential under fourth-round New Jersey Mount Laurel affordable housing planning is zero units, yet the borough carries a fourth-round obligation of 73 affordable units. The response has been overlay zoning along Washington Boulevard and Route 71 at 7th Avenue, plus the AH-1 builder’s remedy zone near 5th Avenue and Washington Boulevard with approximately 19 mixed-use units permitted. Watch the 2026 Borough Council agenda for variance applications, overlay zoning amendments, and any further compliance-driven redevelopment activity — these moves directly affect the borough’s ratable base over the next 3-5 budget cycles. For the complete development-and-zoning analysis, see our Sea Girt NJ real estate and development report 2026.
A drone tour of Sea Girt from The Prodigy Team — the prestige southern shore borough that ranks among the most valuable real estate in New Jersey, the historic 1896 Sea Girt Lighthouse, the distinctive cedar canopy that defines the “Where the Cedars Meet the Sea” motto, the estate-scale Shingle Style and Colonial Revival inventory behind the 2026 median sale price near $3.45 million, and the structural backdrop to the eighth-lowest effective property tax rate (0.520%) of all 53 Monmouth County municipalities.
The Sea Girt Tax Snapshot
Numbers below from the NJ Treasury 2025 General Tax Rates Table, the Monmouth County 2025 County Equalization Table, the NJ DCA MOD-IV 2024 Average Residential Tax Report, and the NJ Department of Education 2025-26 budget reports for the Sea Girt School District.
Sea Girt is one of the most structurally rate-favorable boroughs on the entire Jersey Shore — but the absolute dollars run high because home values run high. The 0.520 percent effective rate is roughly one-quarter of the New Jersey statewide median (1.89%), placing Sea Girt in the same elite Monmouth tier as Spring Lake (0.444%) and Allenhurst (0.528%). The trade-off is the absolute average bill of $15,428 — structurally driven by 2026 median sale prices near $3.45 million per current market data and the zero-RDP redevelopment-only inventory model. For buyers prioritizing prestige southern shore living with established Manasquan-HS-cluster school access and one of Monmouth’s lowest effective rates, Sea Girt delivers a structural value proposition that the most affluent shore buyers consistently identify as best-in-class.
“Sea Girt is where the southern Monmouth shore meets the math of generational wealth preservation. The 0.520 percent effective rate is among the lowest in the state, but the absolute bill of $15,428 reflects what residents are actually paying on $3M-plus homes. The borough is structurally constrained — zero RDP, redevelopment-only growth, state-owned non-taxable land taking a meaningful share of the footprint. For the right buyer, that scarcity is the entire point. Sea Girt is small, exclusive, and structurally locked.”
How Sea Girt Compares: The Prestige Southern Shore
Sea Girt sits in the Manasquan-HS-cluster prestige southern shore tier alongside Spring Lake, Spring Lake Heights, Brielle, Belmar, Avon-by-the-Sea, and Lake Como — seven boroughs that all send their high schoolers to Manasquan Public Schools. The tax math diverges meaningfully across this cluster:
| Prestige Southern Shore (2025) | Sea Girt | Spring Lake | Brielle | Avon | Belmar |
|---|---|---|---|---|---|
| 2025 General Rate | $0.499 | $0.457 | $1.270 | $0.923 | $1.570 |
| 2025 Effective Rate | 0.520% | 0.444% | 1.279% | 0.710% | 0.955% |
| 2024 Avg Bill | $15,428 | $15,257 | $14,206 | $11,326 | $8,944 |
| Population 2020 | 1,866 | 2,909 | 4,755 | 1,933 | 5,706 |
| Median HH Income | $206K | $175K+ | $170K+ | $150K+ | $95K |
| K-8 Structure | Own K-8 | Own K-8 | Own K-8 | Own K-8 | Own K-8 |
| High School | Manasquan HS | Manasquan HS | Manasquan HS | Lottery (M/AP) | Manasquan HS |
Sea Girt and Spring Lake are the two structural-twin boroughs of the prestige Manasquan-cluster tier — nearly identical effective rates (0.520% vs 0.444%), nearly identical average bills ($15,428 vs $15,257), both small (under 3,000 residents), both established affluent boroughs with sub-1.5 sq mi land area, both sending to Manasquan HS, both with Borough Council government. The structural differences lie in the state-government-presence factor: Sea Girt has the NJ State Police Academy plus the NJ Department of Corrections training facility on borough land. Spring Lake has no comparable state presence. For the Spring Lake parallel, see our Spring Lake NJ Property Taxes 2026 deep dive. For the Avon-by-the-Sea lottery sending-district contrast, see our Avon-by-the-Sea NJ Property Taxes 2026 deep dive.
The State Police Academy and the Tax-Exempt Footprint
Sea Girt is structurally unique among Monmouth shore boroughs in having two significant state-government training facilities within its 1.06-square-mile land footprint:
New Jersey State Police Academy. The Academy operates a 25-week residential training program for State Trooper recruits, with on-site barracks housing, classroom and physical-training facilities, and the full administrative footprint of New Jersey’s primary law enforcement training operation. Property tax-exempt as a state-owned facility.
New Jersey Department of Corrections Training Facility. The DOC training operation runs alongside the State Police Academy, with corrections officer training and recertification programs serving the entire state corrections workforce. Also property tax-exempt as a state-owned facility.
The structural implication is meaningful: both facilities occupy land that would otherwise be available for high-value residential development — particularly given Sea Girt’s established 2026 median sale price near $3.45 million. The non-taxable land base reduces Sea Girt’s overall ratable foundation, meaning the borough’s tax math has to work harder on the remaining residential ratables to fund municipal operations. The 0.520 percent effective rate is achieved despite this structural disadvantage — reflecting both the premium per-parcel values of Sea Girt’s residential inventory and the disciplined municipal budget operations under Mayor Fetzer’s administration. For the full development context including the zero-RDP framework that compounds this constraint, see our Sea Girt NJ real estate and development report 2026.
In a 1.06-square-mile land footprint with two significant state-owned tax-exempt parcels, every remaining ratable acre carries proportionally more of the municipal burden. This is the structural foundation of Sea Girt’s relatively higher effective rate compared to Spring Lake (0.520% vs 0.444%) despite similar median sale prices and identical Manasquan-HS sending-district economics. The state-facility footprint is permanent and non-negotiable — it’s the most important non-residential structural factor in Sea Girt’s tax math.
How Your Sea Girt Tax Bill Is Built
A Sea Girt property tax bill combines five independently authorized levies summing to the $0.499 general rate certified for 2025:
Sea Girt Borough Municipal Levy. Funds Borough government — the Borough Council, Mayor Donald Fetzer, Administrator Justin Macko, Municipal Clerk Dawn Harriman, the Sea Girt Police Department, public works, the historic Sea Girt Lighthouse, beach operations, and the borough’s recreation infrastructure. The municipal footprint is structurally lean given the 1,866-resident year-round population and the constrained 1.06-square-mile land area.
Sea Girt School District K-8 Levy + Manasquan HS Tuition. Sea Girt Elementary School operates as the borough’s single in-borough school serving K-8 students. The District then pays per-pupil tuition to Manasquan Public Schools for Sea Girt’s high schoolers attending Manasquan High School — one of seven sending districts feeding into the Manasquan HS regional pool (alongside Avon-by-the-Sea, Belmar, Brielle, Lake Como, Spring Lake, and Spring Lake Heights). The combined K-8 operating budget plus Manasquan HS tuition payments comprise the school portion of the Sea Girt tax bill.
Monmouth County Levy + Library + Open Space. County-level apportionment based on Sea Girt’s equalized property value share of the total Monmouth County base.
County Library + Open Space dedicated levies. Standard statutory components.
“The Manasquan HS economics are favorable for Sea Girt because the cost is spread across seven sending districts. Sea Girt is paying its proportional share but benefiting from the scale of a Manasquan HS operation that serves a much larger combined student body than Sea Girt could ever support alone. This is one of the structural advantages of the cluster: the regional HS model produces better educational economics than any single small borough could deliver independently.”
The Stockton Estate Heritage and the Sea Girt Lighthouse
Sea Girt’s identity is anchored in the late-19th-century estate-development story tied to Commodore Robert F. Stockton. Stockton — a US Navy officer, US Senator from New Jersey, and one of the most consequential 19th-century New Jersey figures — held the original Sea Girt estate land. The borough was named after Stockton’s estate when it incorporated May 1, 1917. The motto “Where the Cedars Meet the Sea” reflects the borough’s distinctive coastal cedar canopy.
The Sea Girt Lighthouse, constructed in 1896 and now operated as a museum, remains one of the borough’s defining civic landmarks. For a borough of 1,866 year-round residents, the lighthouse anchors a tourism and civic-identity infrastructure that punches well above its weight class. Combined with the residential cedar canopy, the Stockton estate boundaries, the Manasquan Inlet frontage to the south, and the Wreck Pond watershed to the north, Sea Girt’s 1.06-square-mile land area is one of the most distinctively-bounded borough footprints in the entire state.
For tax-base purposes, the inventory is structurally constrained — per the borough’s fourth-round Mount Laurel affordable housing planning, Sea Girt’s Realistic Development Potential is zero units. All growth comes from redevelopment, particularly along the Washington Boulevard and Route 71 / 7th Avenue overlay corridors and within the AH-1 builder’s remedy zone near 5th Avenue. For the complete development analysis, see our Sea Girt NJ real estate and development report 2026. For broader Monmouth shore market dynamics, see our three new rules rewriting the New Jersey Shore real estate playbook.
Appeal Deadlines and Tax Court Options
Sea Girt uses Monmouth County’s alternative appeal calendar under the ADP. For why Monmouth runs differently from the rest of New Jersey, see our complete explainer on the ADP framework, the January 15 deadline, and the seven non-ADP towns. Two deadlines apply:
January 15 — for properties assessed under $1 million in true value. Appeals are filed with the Monmouth County Board of Taxation. Given Sea Girt’s 2026 median sale price near $3.45 million, this category covers a smaller share of the Sea Girt ratable base than in most Monmouth boroughs.
April 1 — for properties assessed over $1 million in true value. These owners have the option to file directly with the New Jersey Tax Court rather than the county board. This is the dominant appeal route in Sea Girt — the vast majority of the residential ratable base falls into this category given the median sale price.
For Sea Girt, the appeal economics favor owners with detailed comparable-sales evidence and a thorough understanding of the borough’s constrained inventory dynamics. The redevelopment-only growth pattern, the AH-1 zone implications, and the Mount Laurel obligation context all factor into proper valuation analysis. For county-board mechanics, see the full NJ appeal playbook. For premium-market appeal economics on $1M+ properties — the dominant Sea Girt scenario — see our premium-market appeal playbook.
The Mansion Tax and Closing-Table Math
Sea Girt is the Monmouth borough most directly affected by the 2025 Realty Transfer Fee restructuring. The New Jersey FY2026 Appropriations Act adopted July 10, 2025 replaced the legacy 1 percent Mansion Tax with a graduated rate structure applied to the entire sale price. For Sea Girt sellers transacting at the borough’s 2026 median sale price near $3.45 million, the difference between legacy and new structure can run into six-figure additional closing cost.
The new graduated tiers and the pricing-cliff effects near each threshold boundary are particularly consequential in Sea Girt’s market because the borough’s median sale price already sits well above the $2 million and $2.5 million tier breakpoints. The full breakdown of the 2025–2026 Realty Transfer Fee structure walks through the tier math in detail. For the complete closing-process walkthrough, see the 2026 NJ real estate closing process timeline.
Sea Girt has no active residential PILOT or tax abatement structures — though the AH-1 builder’s remedy zone near 5th Avenue and Washington Boulevard may produce future redevelopment frameworks under the borough’s fourth-round Mount Laurel compliance plan. For contrast on how active PILOTs reshape effective rates in other Monmouth municipalities, see how Long Branch Pier Village condos operate under PILOT.
Tax Relief Programs Available to Sea Girt Homeowners
$250 Veteran Deduction + $250 Senior Citizen / Disabled Persons Deduction available under state income guidelines.
100% Disabled Veteran Property Tax Exemption. Full exemption on the primary residence for honorably discharged veterans with 100% service-connected permanent disability.
At the state level: ANCHOR, Senior Freeze, and Stay NJ apply to qualifying Sea Girt homeowners. Stay NJ reimburses 50 percent of property taxes for eligible homeowners age 65+, capped at $13,000 with a 2024 cap of $6,500. All three programs are now administered through a single combined PAS-1 application. Given Sea Girt’s median age of 56.1 years — among the older demographic profiles in Monmouth — a substantial portion of the resident base is at or near age-65 eligibility for Senior Freeze and Stay NJ. Note: high-income thresholds for Senior Freeze can limit eligibility in a borough with $206K median household income; sophisticated retirees should model their specific income scenarios. For broader context on long-term carrying cost across NJ municipalities, see our analysis of NJ towns with the lowest property taxes.
The 2026 Budget Watch
Sea Girt School District 2026-27 budget. Watch the spring 2026 Sea Girt Board of Education hearings for K-8 operating cost trajectory and Manasquan HS per-pupil tuition adjustments. The seven-sending-district Manasquan HS economics tend to be more stable than single-destination sending arrangements, but cost pressures still flow through.
Borough Council 2026 municipal budget. Mayor Fetzer and the Borough Council adopt the 2026 budget in the first half of the year. Watch for any movement on the AH-1 zone development timeline and the Washington Boulevard overlay corridor activity — both are sources of future ratable expansion that could relieve long-term per-household burden.
Mount Laurel fourth-round compliance. Sea Girt’s 73-unit affordable housing obligation under the fourth round is the most consequential long-term zoning variable. Implementation activity through 2026-2028 will directly affect the borough’s ratable base and the structural balance of the tax math. For the full development analysis, see our Sea Girt NJ real estate and development report 2026.
Annual ADP reassessment cycle. Sea Girt participates in Monmouth County’s annual reassessment program. November 2025 postcards reflected current market values as of October 1, 2025 — an especially important capture point given the borough’s structural redevelopment-driven price dynamics.

“The Mount Laurel fourth-round compliance and the AH-1 zone activity are the two long-term structural variables every Sea Girt owner should monitor. They will reshape the borough’s ratable composition over the next 3-5 years — and that has implications for both individual property values and the overall tax math. Sea Girt has been pragmatic in its compliance approach, but the trajectory matters. Watch the variance applications and the overlay zone development pipeline closely.”
Sea Girt is the structural southern shore prestige borough where one of Monmouth’s lowest effective tax rates (0.520%) meets one of the county’s highest absolute average bills ($15,428) — reflecting median home values near $3.45 million in a 1.06-square-mile borough with zero RDP redevelopment-only growth dynamics. The New Jersey State Police Academy and Department of Corrections training facility occupy substantial tax-exempt land within the borough, structurally constraining the ratable foundation. The Manasquan-HS sending-district economics are favorable, the Stockton estate heritage anchors a distinctive civic identity, and the borough’s 2026 budget cycle hinges on the fourth-round Mount Laurel compliance trajectory. For sophisticated buyers prioritizing genuine scarcity in the Monmouth prestige tier, Sea Girt is one of the most structurally-locked municipalities in New Jersey.
Frequently Asked Questions
What is the 2025 property tax rate in Sea Girt, NJ?
The 2025 general tax rate in Sea Girt is $0.499 per $100 of assessed value, certified by the Monmouth County Board of Taxation and published in the NJ Treasury 2025 General Tax Rates Table. The 2025 effective tax rate is 0.520%, the eighth-lowest in Monmouth County and roughly one-quarter of the New Jersey statewide median of 1.89%.
What is the average property tax bill in Sea Girt?
The 2024 average residential property tax bill in Sea Girt was $15,428 per the NJ DCA MOD-IV Average Residential Tax Report — approximately $4,500 above the Monmouth County average of $10,930 because the borough’s 2026 median sale price near $3.45 million produces substantial absolute dollars even at the eighth-lowest effective rate in the county.
Where do Sea Girt kids go to school?
K-8 students attend Sea Girt Elementary School, the borough’s sole in-borough school. For grades 9-12, students attend Manasquan High School as part of the Manasquan Public Schools sending-receiving relationship. Manasquan HS serves seven sending districts collectively: Avon-by-the-Sea, Belmar, Brielle, Lake Como, Sea Girt, Spring Lake, and Spring Lake Heights.
How does Sea Girt compare to Spring Lake?
Sea Girt and Spring Lake are structural twins: nearly identical effective rates (0.520% vs 0.444%), nearly identical average bills ($15,428 vs $15,257), both small (under 3,000 residents), both established affluent boroughs, both sending to Manasquan HS. The key difference is the NJ State Police Academy plus the NJ Department of Corrections training facility in Sea Girt — substantial tax-exempt state land that Spring Lake doesn’t have. This is the primary reason Sea Girt’s effective rate runs slightly higher than Spring Lake’s.
Why is Sea Girt’s development so constrained?
Sea Girt’s Realistic Development Potential under fourth-round New Jersey Mount Laurel affordable housing planning is zero units. The borough has formally concluded that no meaningful vacant land remains within its borders. All growth must come from redevelopment, principally along the Washington Boulevard and Route 71 / 7th Avenue overlay corridors and within the AH-1 builder’s remedy zone near 5th Avenue. For the complete development analysis, see our Sea Girt NJ real estate and development report 2026.
When is the Sea Girt tax appeal deadline?
January 15 of the tax year for properties assessed under $1 million in true value, filed with the Monmouth County Board of Taxation. April 1 of the tax year for properties assessed over $1 million in true value, filed directly with the New Jersey Tax Court. Given Sea Girt’s 2026 median sale price near $3.45 million, the April 1 Tax Court route is the dominant appeal pathway.
Does Sea Girt have any PILOT properties or tax abatements?
No active residential PILOT structures currently. The AH-1 builder’s remedy zone near 5th Avenue and Washington Boulevard may produce future redevelopment frameworks under the borough’s fourth-round Mount Laurel compliance plan. Every current residential property in Sea Girt pays the standard general tax rate against its full assessed value.
Find Out Where Your 2026 Sea Girt Assessment Should Actually Land
With Sea Girt’s 2026 median sale price near $3.45 million, the redevelopment-only growth pattern, the AH-1 zone dynamics, and the Mount Laurel fourth-round compliance trajectory all in flight, every Sea Girt homeowner should verify their November 2025 postcard reflects accurate current market value. The April 1 Tax Court route is the dominant appeal pathway for the $1M+ ratable cohort. We’ll pull the comps, model the appeal economics including the structural redevelopment-impact variables, and tell you whether the case is worth bringing before the spring 2026 windows close.
