Morris Property Tax: Rates, Deadlines & Appeals (2026)

The regular 2026 Morris County property-tax assessment appeal deadline was April 1, 2026; if a municipal-wide revaluation or reassessment was implemented for your property, the deadline was May 1, 2026. File with the Morris County Board of Taxation at 30 Schuyler Place, Morristown, NJ 07960 or by mail to P.O. Box 900, Morristown, NJ 07963-0900—the appeal must be received, not merely postmarked, by the deadline.

For the next regular assessment year, plan around April 1, 2027, unless your municipality’s assessment notice triggers a later 45-day or revaluation/reassessment deadline.

How assessments work in Morris County

Morris County does not set one countywide home value. Your municipal tax assessor sets your assessment, and the Morris County Board of Taxation maintains county tax records, sets tax rates and equalization ratios, supervises municipal assessors, reviews assessments, orders revaluations when necessary, and rules on taxpayer assessment appeals.

New Jersey’s assessment date is October 1 of the pretax year. For a 2026 appeal, you are trying to prove what the property was worth as of October 1, 2025—not what it is worth on the hearing date and not whether your tax bill feels too high. Morris County’s own hearing guide is blunt: tax appeals are on assessments only, not taxes, and your assessment is presumed correct until you prove otherwise.

The key Morris/NJ concept is Chapter 123. In a normal year, the Tax Board compares your assessment to your property’s proven market value, then tests that ratio against your municipality’s average ratio and its 15% common-level range. For tax year 2026, for example, Parsippany-Troy Hills had a Chapter 123 average ratio of 66.60%, with a lower limit of 56.61% and an upper limit of 76.59%. If your assessment divided by proven true value is above the upper limit, the assessment should be reduced to true value times the average ratio. If it is within the range, you usually get no change.

In a revaluation or reassessment year, Morris County says the common level is 100%, so the question becomes more direct: does the new assessment exceed true market value as of the October 1 assessment date? The statewide rule gives a May 1 appeal deadline when a municipal revaluation or reassessment has been implemented.

Whether you should appeal

Do not appeal just because your tax bill rose. In Morris County, school, municipal, county, library, open-space, fire-district and other budgets can raise taxes even if your assessment is fair. Appeal only if you can show the assessed value is too high under the Chapter 123 test.

Start with three numbers:

1. Your total assessment from the assessment notice or Morris County Tax Board property search.
2. Your municipality’s 2026 Chapter 123 ratio and upper limit from the state Chapter 123 table.
3. Comparable sales that closed before October 1, 2025, preferably in the same town, neighborhood, school district and housing type.

A quick test: divide your assessment by a realistic market value supported by comps. If the result is above the municipality’s upper limit, you may have a case. If it is within the range, the Board may leave the assessment alone even if the home would sell for less than the assessment.

Morris County does not appear to publish countywide appeal success rates, median reductions, or average homeowner savings in a simple official report. The official site does provide a Search Appeal Records tool, which is useful for seeing prior judgments by town, block/lot or owner, but do not treat another property’s assessment as evidence—Morris County and the state both emphasize that comparable sales, not comparable assessments, are acceptable proof.

Also check relief programs before assuming an appeal is the only way to lower out-of-pocket cost. New Jersey homeowners may qualify for ANCHOR, Senior Freeze and Stay NJ through the property-tax relief application; the 2026 filing deadline for that relief application is November 2, 2026. Separate local deductions include the $250 senior/disabled deduction, the $250 veteran deduction, and the 100% disabled veteran property tax exemption for qualifying principal residences.

Step-by-step how to file

1. Contact your municipal assessor first. Morris County recommends checking the property facts and discussing the assessment before filing. Ask for your property record card and verify square footage, bathrooms, finished basement, lot size, condition and classification.

2. Pull comparable sales. Use 3 to 5 sales that occurred before October 1, 2025 for a 2026 appeal. The state’s Form A-1 Comp. Sale — Comparable Sales Analysis Form is designed for this. Comparable sales should be similar in location, lot size, age, style, square footage, condition and use.

3. Complete the right form. For a regular assessment appeal, use Form A-1, Petition of Appeal. For an added or omitted assessment, use Form AA-1, Added/Omitted Petition of Appeal; those appeals have a separate December 1 deadline. If you rely on sales, include Form A-1 Comp. Sale or equivalent comparable-sale detail.

4. File the original with the Morris County Board of Taxation. Morris County lists the Board location as 30 Schuyler Place, Morristown, NJ 07960 and the mailing address as Morris County Board of Taxation, P.O. Box 900, Morristown, NJ 07963-0900. The office phone is 973-285-6707. As of the current official NJ Appeal Online member list, Morris County is not one of the counties accepting electronic filings through that portal; the listed online portal counties are Hudson, Monmouth and Union. Do not assume email filing is accepted—Form A-1 requires an original petition and signature, and the instructions require filing the original with the county board.

5. Serve copies. Form A-1 requires copies, with attachments, to be served on both the municipal assessor and the municipal clerk for the town where the property is located. Keep a full copy for yourself.

6. Pay the filing fee. The A-1 fee is based on assessed valuation: $5 if under $150,000; $25 from $150,000 to under $500,000; $100 from $500,000 to under $1,000,000; and $150 for $1,000,000 or more. Classification appeals are $25. Checks are payable to County Tax Administrator, and fees are nonrefundable. No fee is required for appeals of denied senior/disabled or veteran deductions listed in the A-1 instructions.

7. Pay first-quarter taxes. New Jersey requires taxpayers appealing an assessment to have paid taxes and municipal charges due through the first quarter, unless the board relaxes that requirement.

What happens after

The proper appeal authority is the Morris County Board of Taxation, often called the Morris County Tax Board. It consists of five commissioners appointed by the Governor, and hearings are public meetings presided over by one or more tax commissioners. Morris County states that it is holding in-person tax appeal hearings only—no virtual hearings.

Form A-1 includes an option for a summary hearing, meaning the Board decides based on the evidence submitted without your appearance. Use that cautiously. If your comparables need explanation, if you have condition issues, or if the municipality contests your evidence, being present is usually better. If you submit an appraisal, the appraiser must appear to testify.

The municipality is the opposing party. The municipal attorney may appear, and the assessor or appraiser may testify. Morris County also says municipal assessors or their representatives are required to inspect appealed properties before the hearing and be present to testify. Hearings are scheduled during the workweek, generally starting at 9:30 a.m. Adjournments are generally denied; missing the hearing can lead to dismissal for lack of prosecution.

Bring concise evidence: your requested assessment, your value conclusion as of October 1, 2025, 3 to 5 comparable sales, photos, property record errors, and any special-condition proof. Appraisal reports must be provided to the assessor and to the Board at least seven days before the hearing, with enough copies for the administrator and commissioners.

Morris County says the Board usually renders a decision 6 to 8 weeks after the hearing. If you disagree, you have 45 days from the date the judgment was mailed to file with the Tax Court of New Jersey. Properties assessed above $1,000,000 may file directly in Tax Court instead of the county board.

Local tips

Use Morris County’s own tools. The Board’s site links to tax records, tax maps, appeal records, SR1A sales records and a Chapter 123 worksheet. Before filing, compare your facts against the county property record and look up deed dates and sale prices.

Be careful in high-ratio towns. For 2026, several Morris municipalities have Chapter 123 upper limits over 100%, which the state treats as 100%. In those towns, you may need to prove your assessment is above actual market value, not merely above a lower equalized figure.

Worked example using a real Morris rate: assume a Parsippany-Troy Hills home is assessed at $700,000. The owner’s best comparable sales support a true value of $850,000 as of October 1, 2025. The assessment-to-value ratio is 82.35% ($700,000 / $850,000), which exceeds Parsippany’s 2026 upper limit of 76.59%. Applying the 2026 average ratio of 66.60% gives a corrected assessment of $566,100. That is a $133,900 assessment reduction. Using Parsippany’s latest published 2025 general tax rate of 3.452 per $100 of assessed value, the rough annual tax savings would be about $4,622 ($133,900 × 0.03452). Actual savings depend on the final tax rate and judgment timing.

Finally, do not ignore exemptions. A successful appeal lowers the assessment; ANCHOR/Senior Freeze/Stay NJ and deductions lower out-of-pocket taxes in different ways. Many Morris homeowners should check both tracks.

Morris County Property Tax Rate

County tax-rate component: $0.232 per $100 of equalized value; Morris County’s 2026 adopted budget states there was no county tax-rate increase for a seventh consecutive year. Total homeowner tax rates are not one countywide rate in New Jersey; Morris County’s Board of Taxation publishes general tax rates by municipality/taxing district.

When Are Property Taxes Due in Morris County?

Quarterly property-tax installments are due February 1, May 1, August 1, and November 1. Four installments: first installment February 1, second May 1, third August 1, fourth November 1.

This is not the same as the assessment appeal deadline above. The appeal deadline is your window to contest your assessed value; the payment due date is when the resulting tax bill must be paid. Missing one does not affect the other, but missing either has real consequences — one forfeits your right to appeal for the year, the other can trigger penalties and interest.
