This form is a formal complaint filed with the Tax Court of New Jersey to correct a typographical error, transposition error, or other mistake in a property tax assessment under N.J.S.A. 54:51A-7. It is used for factual errors, not for disputes over the assessor's opinion of the property's value. Filing this complaint is a crucial step for taxpayers to ensure their property assessment is accurate and their tax liability is correct. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

13 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Verifies Original Assessment Calculation

This check validates that the sum of the 'Land' (OrigAssmtLand) and 'Improvements' (OrigAssmtImprvmts) values equals the 'Total' (OrigAssmtTtl) value for the original assessment. This is crucial for data integrity and prevents filings based on simple mathematical errors. A mismatch would require the user to correct the values before submission.

Verifies Corrected Assessment Calculation

This check validates that the sum of the 'Land' (OrigAssmtLand1) and 'Improvements' (OrigAssmtImprvmts1) values equals the 'Total' (OrigAssmtTtl1) value for the corrected assessment. Similar to the original assessment check, this ensures the requested relief is mathematically sound. If the numbers do not add up, the court cannot process the requested change accurately.

Checks Complaint Against Statutory Filing Deadline

This is a critical logical check based on N.J.S.A. 54:51A-7. It verifies that the complaint's filing date (attyDt) is no later than the end of the third tax year following the tax year being corrected (assmtYrs). For example, a complaint for tax year 2020 must be filed by December 31, 2023. Failure to meet this jurisdictional deadline will result in the case being dismissed.

Ensures Affidavit Details are Provided

This validation confirms that the text area for explaining the facts of the error (affDetails) is not empty. The affidavit is the core evidentiary basis for the complaint, and its absence makes the filing incomplete and without merit. The form cannot be submitted without a detailed explanation of the error.

Confirms All Three Proofs of Service are Completed

The form requires serving the complaint on the municipal clerk, the assessor, and the county board of taxation. This validation ensures that dates (posDt1, posDt2, posDt3) and taxing district names (assessDist1, assessDist2) are entered for all three required service certifications. An incomplete proof of service can invalidate the filing and lead to dismissal for failure to properly notify all parties.

Validates Service Dates Relative to Complaint Date

This check ensures that the dates listed in the Proof of Service section (posDt1, posDt2, posDt3) are on or before the main complaint signature date (attyDt). It is logically impossible to serve a copy of a complaint before it has been finalized and signed. This validation prevents procedural errors that could be grounds for challenging the validity of the service.

Common Mistakes in Completing CN 10335

The ones the AI is built to catch.

Forgetting to Attach the Case Information Statement (CIS)
The form's notes explicitly state that a 'Local Property Tax Correction of Error Case Information Statement must be attached to the face of the complaint.' Filers often overlook this separate required document, focusing only on the complaint and affidavit. An incomplete filing will be rejected by the Tax Court Management Office, causing significant delays and potentially risking the filing deadline.
Using the Form for a Valuation Dispute
This complaint is strictly for 'typographical error, an error in transposition or a mistake,' not for challenging an assessor's judgment on property value. People mistakenly use this form to argue their property is over-assessed, which requires a standard tax appeal. This fundamental error will lead to the complaint's dismissal, wasting time and filing fees.
Submitting an Incomplete or Invalid Affidavit
The affidavit is a sworn statement and the core evidence for the complaint. Common mistakes include failing to have it signed in the presence of a Notary Public, forgetting the notary's signature and seal, or having someone without direct knowledge of the facts sign it. An invalid affidavit renders the entire complaint legally insufficient and will result in its rejection or dismissal.
Providing an Insufficient Factual Basis in the Affidavit
The affidavit requires a detailed explanation of 'the facts causing or constituting the error(s).' Filers often provide vague statements like 'the assessment was a mistake' instead of specific facts, such as 'the assessor incorrectly listed the property as having a two-car garage when it only has a one-car garage.' Without a clear, factual basis, the court has no grounds to grant the correction, leading to denial of the complaint.
Failure to Serve All Three Required Parties
The 'Proof of Service' page requires serving the complaint on three distinct parties: the municipal clerk, the municipal assessor, and the county board of taxation administrator. Filers frequently miss one of these parties, believing service on the town is sufficient. Failure to properly serve all three entities results in defective service, which is grounds for the court to dismiss the entire case.
Filing Past the Statute of Limitations
The form notes specify that the complaint must be filed 'not later than the end of the third tax year following the tax year for which the correction is sought.' Many filers are unaware of or miscalculate this strict deadline. Filing even one day late will result in the complaint being permanently time-barred and dismissed by the court.
Mathematical Errors in Assessment Values
The form requires listing original and corrected assessment values for Land, Improvements, and a Total. Filers often make simple addition errors where the Land and Improvements values do not sum to the stated Total. These mistakes undermine the filing's credibility and create confusion. AI-powered form filling tools like Instafill.ai can prevent this by performing automatic calculations and validating totals.
Forgetting to Sign or Date Critical Sections
A legal complaint requires signatures to be valid, but filers often forget to sign the main complaint (Page 1) or the Proof of Service certification (Page 3). An unsigned document is not legally binding and will be rejected by the court clerk, halting the process until a properly signed version is submitted. This is a common oversight when dealing with multi-page documents.
Including Confidential Personal Identifiers
Court rules mandate the redaction of sensitive information like Social Security or driver's license numbers. People sometimes attach supporting documents without redacting this information, making private data part of the public record and creating a risk of identity theft. It is the filer's sole responsibility to redact this information before submission, as court staff will not do it for them.
Submitting an Illegible Handwritten Form
This form is often available as a non-fillable PDF, leading people to fill it out by hand. Illegible handwriting can cause data entry errors by court staff or make the complaint difficult to understand, leading to delays or rejection. To avoid this, tools like Instafill.ai can convert the non-fillable PDF into an interactive, fillable version, ensuring a clean, typed, and professional submission.
