Most residents and certain nonresidents must file a New Jersey tax return for 2024 if their gross income exceeds the state’s filing thresholds. The New Jersey Division of Taxation updates these thresholds annually, depending on filing status and age.
The groups listed below are mandated to submit a filing:
Individuals who lived in New Jersey for only part of 2024 must file as part-year residents, reporting only the income earned during their residency.
In addition, sole proprietors and single-member LLCs must report business income on their personal NJ-1040 using Schedule NJ-BUS-1. If business net earnings were $400 or more, filing is required under the sole proprietor NJ tax filing rules, even if total income is below the general thresholds.
The New Jersey Division of Taxation updates its tax rules and benefit programs annually. For the 2024 tax year, several key changes may affect how you calculate your tax liability, file your return, or claim specific credits. Understanding these updates ensures compliance and may help you avoid underpayment penalties or missed refunds.
Beginning October 1, 2024, the full sales tax exemption for zero-emission vehicles will no longer apply. Instead, these vehicles will be taxed at a reduced rate of 3.3125% through June 30, 2025. After that date, they will be taxed at the standard 6.625% rate. This change impacts individuals and businesses considering a new vehicle purchase during the tax year. For more information, visit the New Jersey Division of Taxation.
The sales tax holiday on school supplies, computers, and sports or recreational equipment has been discontinued as of October 1, 2024. All such purchases are now subject to the full state sales tax. This is a significant update for families and educators who previously planned purchases around the annual holiday.
For 2024, the New Jersey Earned Income Tax Credit (NJEITC) has increased to 40% of the federal EITC amount. This credit offers substantial support for eligible low- to moderate-income filers. If you were a part-year resident, your credit will be prorated based on the months you lived in New Jersey. Learn more about the NJEITC on the official tax credit page.
These New Jersey tax changes for 2024 may affect your overall tax liability, refund eligibility, and planning decisions. Always refer to official sources before filing.
To complete your New Jersey tax return, you must use the correct forms issued by the New Jersey Division of Taxation. Filing with the appropriate forms helps reduce common issues that could delay your processing time or impact your refund status. Whether you choose online filing or submit a paper return, using official forms is essential.
If you are a primary taxpayer with complex income sources or prior adjustments, you may need to provide supporting forms to prevent rejections or delays in follow-up services.
The Division of Taxation encourages online filing through its Enterprise Services Portal, which offers secure options for submitting your taxes online and paying via e-check or credit card. Remember to include your Social Security number on all forms when using paper returns. You can get federal guidance from the Internal Revenue Service or speak with the Division directly if you have specific tax questions.
Filing your New Jersey tax return accurately involves gathering the correct documents, completing the required forms, and submitting them through your preferred method. A straightforward, step-by-step process can help reduce mistakes, avoid delays, and ensure your return is processed efficiently.
To begin, collect all documents that verify your income, deductions, and payment details:
The primary taxpayer needs to fill out all of the personal and income sections completely:
Carefully review the entire return. If you are filing a paper return, sign it and attach all W-2s and supporting schedules. If you are filing taxes online, follow the confirmation steps to ensure your account is credited correctly. Errors in basic details, especially your Social Security number, are among the most common issues that delay processing.
Small business owners in New Jersey must follow specific state rules when filing taxes and reporting their income. If you are a sole proprietor or own a single-member LLC, you report your business income directly on your New Jersey tax return. The state does not tax these groups separately, but the Division of Taxation does have specific rules for documentation and filing that they must follow.
As a business owner, you must complete the federal Schedule C, which details your income, expenses, and net earnings from self-employment. This information is then used to complete Schedule NJ-BUS-1, the state’s official form for summarizing business income for New Jersey residents. The total from NJ-BUS-1 is transferred to Line 17 of the NJ-1040, the standard income tax return for New Jersey residents.
You must file a New Jersey tax return if your net self-employment income was $400 or more—even if your total income falls below the general threshold for other individual filers. This rule applies to sole proprietors and single-member LLCs and reflects the state’s approach to capturing income from informal or unincorporated business activities.
It is important to note that New Jersey does not follow specific federal tax code provisions. The New Jersey Division of Taxation does not allow deductions for contributions to SEP IRAs, SIMPLE IRAs, or other qualified retirement plans. In addition, the state does not recognize that the Qualified Business Income (QBI) deduction is permitted under federal law. These differences may result in a higher state tax liability than your federal return.
The Treasury Division recommends using its secure online filing system for small business owners. This platform reduces errors, allows faster processing, and lets you track your refund status through the portal. Electronic submission also provides confirmation and timely access to updates, making it the preferred option for most filers with business income.
New Jersey offers two main options for filing your state income tax return: submitting a paper return or using the online filing system. The Division of Taxation accepts both methods, but they have different timelines, payment procedures, and advantages. Choosing the correct method can help reduce errors and improve your ability to track your refund status.
The Treasury Division strongly encourages electronic submission through its Enterprise Services portal or approved tax software. This system supports both individuals and small business owners.
The key benefits of filing online are as follows:
Electronic payments made by e-check do not include a processing fee. If you choose to pay by credit or debit card, the card processor may apply a separate service fee, which is not collected by the state.
Taxpayers who do not wish to file electronically may complete a paper return and mail it to the appropriate address. You must include all W-2s, 1099s, required schedules, and signatures. Mailing addresses vary depending on whether you owe tax, expect a refund, or have no balance due.
Paper returns typically take longer to process. If you file by mail, you may not receive refund status updates for 10 to 12 weeks after submission.
If you need to answer specific tax questions, clarify your filing method, or resolve an issue with your return, you can contact the New Jersey Division of Taxation directly.
Assistance is available for individuals and business filers, including those using Enterprise Services or submitting a paper return.
If you owe taxes on your New Jersey income tax return, the state offers several approved payment options. Paying your balance in full and on time is critical to avoid penalties, interest, or delays in your refund status if you also expect a refund from overpayments or credits. The Division of Taxation recommends choosing the most secure and traceable method available.
Taxpayers may choose from the following payment options:
Full payment of your 2024 tax liability is due by April 15, 2025, even if you request a filing extension. Failure to pay on time may result in:
To prevent delays in your refund status, ensure all payments are submitted promptly and marked with the correct identifying information.
After submitting your New Jersey income tax return, it is essential to verify the outcome—whether you are due a refund or owe additional tax. The New Jersey Division of Taxation offers multiple ways to check your account activity and stay updated throughout the tax season.
If you are expecting a refund, you can check its status using one of the following methods:
Allow four weeks before checking electronic returns. Paper returns may require 12 weeks or more for processing.
You can log in to the New Jersey Online Payment Service using your identifying information to view any outstanding balance. The system will display your current balance, including applicable penalties or interest.
Always wait to accept your return formally before reviewing payment or balance information. This ensures that the most accurate and up-to-date account data is reflected.
Completing a thorough final review before submitting your income tax return for New Jersey is essential. This checklist is designed to help you verify that your return is complete, accurate, and compliant with all state requirements. A careful review may help you avoid delays, rejections, or inquiries from the Division of Taxation.
Before filing, carefully review your return for mathematical accuracy and completeness. Ensure the correct total tax, refund, or balance due is reported. You must sign and date the return; both spouses must sign if you file jointly. Attach all required documentation, such as W-2s, 1099s, and supplemental schedules. If mailing a paper return, use the proper address based on whether you are sending a payment. Finally, keep a complete copy of your return and all supporting records for at least four years if the Division requests additional information.
If you miss the filing deadline, you should submit your return as soon as possible to reduce penalties and interest. New Jersey applies a late filing penalty of 5% per month, up to 25% of the unpaid tax. If you are due a refund, there is no penalty, but delays in filing may postpone your refund.
Many taxpayers qualify to file for free using the state’s online Fill’nFile system or approved free file programs. These services are available through the Division of Taxation’s website and may include income-based eligibility limits. Filing electronically is recommended for faster processing and confirmation.
Commonly missed items include the New Jersey property tax deduction or credit, the earned income tax credit (NJEITC), and the tax credit paid to other jurisdictions. Some taxpayers forget to deduct excess unemployment or workforce development contributions withheld by mistake. Reviewing all forms and instructions can help you avoid leaving money unclaimed.
To request an extension, you must either file Form NJ-630 with the Division of Taxation or submit a federal extension with the IRS. The extension gives you until October 15, 2025, to file. However, it does not extend your payment deadline. At least 80% of your estimated tax must be paid by April 15 to avoid penalties.
If you filed a joint federal return, you may file a joint New Jersey return even if one spouse lived outside the state for part of the year. You must file as a part-year resident and indicate each spouse’s residency period. New Jersey income must be allocated accordingly.
If you discover an error after filing, you must file an amended return using the same form (NJ-1040) and mark it as “AMENDED.” Include a written explanation of the changes and any documentation that supports the correction. Submit all forms to the Division of Taxation by mail.
Stimulus payments and most federal relief benefits are not taxable for New Jersey purposes. However, all unemployment compensation—including federal pandemic unemployment benefits—is taxable. Remember to include this income on your return and retain Form 1099-G for your records.
