Burlington County, NJ property tax appeal guide for 2027

What deadline matters first

For the 2027 regular appeal, plan around January 15, 2027. Burlington County uses New Jersey’s alternative assessment calendar, so the regular deadline is January 15, or 45 days from completion of the Notice of Assessment bulk mailing if later. Paper and online cutoff times are different.

A Notice of Assessment (NOA) is the postcard or assessment notice that tells you the value the assessor plans to use for the coming tax year. Burlington County says the NOA postcard is expected in November of the pre-tax year, and an aggrieved property owner may file with the Burlington County Board of Taxation within 45 days of the NOA mailing date. The county also states that the filing deadline is January 15 unless that date is affected by a holiday or a later NOA mailing date (Burlington County tax appeal page).

For the 2027 cycle, the verified policy snapshot expects the NOA in November 2026 and a regular appeal due by January 15, 2027, or 45 days from completion of the NOA bulk mailing if later. If the deadline falls on a weekend or legal holiday, it moves to the next business day. January 15, 2027 is a Friday.

Burlington County’s posted 2026 regular online window opened December 3 at 12:01 a.m. and closed January 15 at 11:59 p.m. Because the 2027 online opening had not been posted as of this analysis on 2026-06-21, TaxSauce uses a conservative projected online opening of December 3, 2026 at 12:01 a.m. Eastern. Paper filings are typically due by 4:00 p.m. Eastern on the deadline, while online filing remains available until 11:59 p.m. Eastern (Burlington County tax appeal page).

As background volume, New Jersey’s 2025 county tax board report listed a Burlington County appeal count of 236 total appeals, including 119 residential appeals by classification and $13,476,301 in total assessed valuation reductions. That volume statistic is not a prediction for any individual homeowner (New Jersey 2025 property tax appeals summary).

The common value appeal

The usual value filing is Section I - Appeal of Real Property Valuation. This is where you argue that the assessment is too high because the property’s market value as of October 1, 2026 is lower than the assessment supports. You need evidence, not just a higher tax bill.

For tax year 2027, the valuation date is October 1, 2026. Burlington’s Form A-1 instructions say the taxpayer must demonstrate the property’s market value as of October 1 of the preceding pre-tax year, and that only the property value can be appealed, not the amount of taxes on the property (Form A-1 instructions).

The county’s approximate effective tax rate benchmark in this policy is 2.22%. This is useful only as a rough comparison point. New Jersey publishes municipal effective tax rates for comparison at 100% valuation and cautions that those rates are not used to compute an individual tax bill (New Jersey 2025 general tax rates).

That means a lower assessment may lower the taxable value used in the bill calculation, but the appeal itself is not a request to change the tax rate. Your evidence should focus on what a willing buyer would likely have paid for your property as of October 1, 2026.

Other reasons you might appeal

Burlington County’s Form A-1 also lists non-value reasons, including deduction denials, exemption denials, Farmland Assessment Classification, and Discrimination / Common Level Range Standard. These are different from proving a lower market value. Read the official label carefully and attach the denial notice when the form requires it.

Official non-value labels from the policy include:

• Discrimination / Common Level Range Standard: This is a Chapter 123 ratio issue. In plain English, after true value is shown, the assessment may be revised if the ratio of assessed value to true value is outside the permitted common level range for the municipality (Form A-1 instructions).
• Denial of Veteran's Property Tax Deduction: Use this when you are contesting a written denial of the veteran deduction. The form says to attach a copy of the denial notice for Section III deductions, classifications, and exemptions (Form A-1 instructions).
• Denial of Senior Citizen/Disabled Person Property Tax Deduction: Use this when the senior citizen, disabled person, or eligible surviving spouse or partner deduction was denied. Attach the denial notice if you file under Section III (Form A-1 instructions).
• Denial of 100% Disabled Veteran Exemption: Use this when the 100% disabled veteran exemption, or a related surviving spouse or partner exemption, was denied. This is an exemption dispute, not a comparable-sale value argument (Form A-1 instructions).
• Farmland Assessment Classification: Use this when the dispute is about Farmland Assessment classification. The issue is whether the property qualifies for the classification, not simply whether the home value is too high (Form A-1 instructions).
• Abatement or Exemption - Religious, Charitable, etc.: Use this for an abatement or exemption dispute, including religious, charitable, and similar exempt-property claims. Attach the written denial notice when the form calls for it (Form A-1 instructions).

If your Notice of Assessment says something else changed

A Notice of Assessment is the postcard or notice showing the assessment for the coming tax year. If you receive a Notification of Change of Assessment or an Added/Omitted Assessment, do not assume the regular January 15 rule is the only deadline. Those notices can have separate timing and forms.

Burlington’s Form A-1 instructions say a taxpayer has 45 days to file an appeal upon issuance of a Notification of Change of Assessment. The same instructions say Burlington, Monmouth, and Gloucester County regular appeals are due by January 15 or 45 days from completion of the Notification of Assessment bulk mailing, whichever is later (Form A-1 instructions).

An Added/Omitted Assessment usually means the municipality added value after the regular assessment cycle, often because a property improvement or omitted property was added to the tax list. Burlington County’s page says an Added/Omitted Assessment appeal is due on or before December 1, with paper forms physically present by 4:00 p.m. and online filing due by 11:59 p.m. on that date (Burlington County tax appeal page).

New Jersey’s Division of Taxation says an added or omitted assessment can be appealed by filing Form AA-1 with the County Board of Taxation. It also notes that if the aggregate assessed valuation for an added or omitted assessment exceeds $750,000, the appeal may be made directly to the Tax Court of New Jersey (NJ Division of Taxation assessment and appeals).

What evidence helps

The strongest evidence is usually recent, arm’s-length sales of similar homes in the same municipality or neighborhood. Burlington’s Form A-1 allows no more than five comparable sales. Include block, lot, sale price, and deed date, and serve the assessor, municipal clerk, and county board on time.

For the 2027 regular valuation appeal, TaxSauce uses a conservative comparable-sale window of October 1, 2025 through October 1, 2026, because the county and state instructions do not publish a fixed lookback window. Sales closest to October 1, 2026 are generally more persuasive, especially when they are similar in property type, style, age, condition, living area, lot characteristics, and location.

Burlington’s instructions say no more than five comparable sales may be submitted to the assessor, clerk, and county board of taxation no later than seven calendar days before the hearing if the sales were not included with the petition. Each comparable should include block, lot, sale price, and deed date (Form A-1 instructions).

Comparable sales should be open-market, arm’s-length sales. In plain English, that means a normal sale between a willing buyer and a willing seller, with neither side forced to act. New Jersey’s non-usable deed categories include many transactions that may need to be excluded or investigated, such as immediate-family transfers, sheriff’s sales, bankruptcy or receivership sales, short sales, transfers in lieu of foreclosure, and first sales after foreclosure by a financial institution (New Jersey non-usable deed regulation).

Comparable assessments and taxes on other properties are not enough. Burlington’s instructions state that comparable sales of real property are acceptable evidence of market value, while comparable assessments are unacceptable as evidence of value (Form A-1 instructions).

If you rely on an appraisal report for expert testimony, the report must be supplied at least seven calendar days before the county board hearing, and the appraiser must appear to testify unless the board waives the requirement. Income-producing property should include income and expense information for the most recently completed accounting year and any additional years requested by the board (Form A-1 instructions).

What the board can and cannot decide

The Burlington County Board of Taxation can decide whether the assessment should be revised under the market value or common level range standards. It cannot lower your taxes just because the bill feels unaffordable. The appeal is about the assessment, not the tax rate or municipal budget.

The county board is the official appeal body for regular county tax board appeals. Burlington County describes the board as certifying property records from municipal assessors for properties in the county’s 40 municipalities, with preliminary tax list information on November 1 and final tax list information on May 5 (Burlington County Board of Taxation).

New Jersey says property owners have the right to file tax appeals with the County Board of Taxation, and that a taxpayer must prove the assessed value is unreasonable compared with a market value standard. It also explains that an assessment can be excessive or discriminatory under the True Market Value Standard or Common Level Range Standard (NJ Division of Taxation assessment and appeals).

If you are not satisfied with the county board judgment, New Jersey says you may file with the Tax Court of New Jersey within 45 days of the county board judgment date. Properties with assessments greater than $1,000,000 may also have the option to file directly with the Tax Court for a regular assessment appeal (NJ Division of Taxation assessment and appeals).

How TaxSauce helps

TaxSauce helps you estimate whether the assessment looks high, organize comparable sales, flag evidence gaps, and prepare a homeowner-friendly packet for review. You stay in control. You choose whether to file, confirm the facts, sign the forms, and submit them to the county or online system.

For Burlington County, TaxSauce can help you line up the dates that matter: the October 1, 2026 valuation date, the expected November 2026 Notice of Assessment timing, the projected December 3, 2026 online opening, the January 15, 2027 regular deadline, and the seven-calendar-day evidence deadline before the hearing.

TaxSauce can also help you screen sales so you are not relying on weak evidence. For example, it can help separate nearby arm’s-length sales from transactions that may be non-usable or require extra investigation, then organize up to five comparables with the block, lot, sale price, and deed date.

TaxSauce does not promise that the board will reduce your assessment. The goal is to help you understand the official process, prepare a clear packet, and avoid common mistakes such as arguing only that the tax bill is too high.
