Filing your New Jersey state tax return for 2017 may feel like a challenge, especially if you’re unfamiliar with the process or haven’t handled a prior-year filing before. Whether you are a first-time filer, a small business owner, or an individual taxpayer catching up on past obligations, this guide will help you understand exactly how to file a New Jersey tax return for 2017 accurately and efficiently. We’ll walk through the required forms, filing options, payment methods, and tips to avoid common mistakes so you can confidently submit your return.
The Treasury Division of Taxation oversees all state income tax filings in New Jersey, and it is essential to follow their requirements closely to avoid delays. Even though the original due date for 2017 returns was April 15, 2019, some taxpayers still need to file—whether to claim a refund, pay remaining taxes, or respond to a letter from the department. Filing the correct paper return or using approved online tax services ensures that your submission is processed smoothly and your refund status can be tracked without unnecessary issues.
Completing your return correctly helps speed up the process and reduce the likelihood of follow-up correspondence. You’ll need details such as your Social Security number, income documents, and any records of prior payments. Whether you plan to pay taxes by check, credit card, or e-check through the state’s enterprise services portal, understanding each step in advance can save you weeks of delays. In the following sections, we’ll break the process into manageable steps, making it easy for taxpayers to meet their obligations and take advantage of every deduction or credit available.
Before you prepare your 2017 New Jersey state income tax return, you must understand who must file and what rules apply during that year. The Division of Taxation set income thresholds based on filing status. You must submit a return if your gross income was at least $10,000 as a single filer or married filing separately. For married couples filing jointly, heads of household, and qualifying widows (er), the threshold was $20,000. Even if your income was below these amounts, you may still have to file to claim a refund, take advantage of credits, or reconcile taxes you already paid.
There are also situations where filing is necessary regardless of income level. For example, you must submit the proper form if you had taxes withheld from your paycheck and want that money back. The same is true if you made estimated payment installments, are eligible for the New Jersey Earned Income Tax Credit, or qualify for other refundable credits. Filing ensures the department has an accurate record of your taxpayer information and allows you to track your refund status through official services. Choosing to mail a paper return or use approved online tax options is generally up to you, but the method should fit your preferences and timeline.
Several key updates in 2017 could impact your tax return. The retirement income exclusion increased, allowing eligible taxpayers to exclude up to $40,000 in pension and retirement income if their total income was $100,000 or less. A new $3,000 veterans exemption was introduced for honorably discharged service members, which a spouse could also claim on a joint return. Additionally, the sales tax rate dropped from 7% to 6.875% on January 1, 2017, affecting usage tax calculations for certain purchases. By understanding these rules and changes before you pay taxes, you can ensure your return is accurate, your process is efficient, and your interaction with the Treasury Division runs smoothly.
Filing your 2017 New Jersey state tax return starts with using the correct forms. Form NJ-1040 (New Jersey Resident Return) is the primary document for full- and part-year residents. Issued by the Treasury Division of Taxation, this form is used by individual taxpayers to report income tax, claim deductions or credits, and calculate any refund or payment due. You can submit it as a paper return by mail or through approved online tax services.
In many cases, additional schedules and forms will be needed to complete the process:
When you pay, always write your Social Security number and “2017” on the check to ensure the department credits it to the correct taxpayer account. If paying electronically, keep confirmation records if you need to verify your status or resolve a follow-up letter from the Division.
All official forms for 2017, including instructions, are available on the New Jersey Division of Taxation Prior Year Income Tax Forms page. Using the correct documents from this source helps ensure your filing is accurate, complete, and processed without unnecessary delays.
Filing your 2017 New Jersey tax return is easier when you break it down into manageable steps. Following this process carefully can reduce errors, avoid delays from the Treasury Division, and ensure your refund or payment is handled correctly.
Before you begin, collect all necessary paperwork. This includes your W-2 forms showing wages and state tax withheld and 1099 forms for other income sources such as retirement benefits, self-employment earnings, or investment income. You’ll also need bank account details for direct deposit, property tax records if claiming a deduction or credit, and your prior year’s return for reference. Having these documents ready helps the process move more quickly.
On Form NJ-1040, enter your name in the required format (last name first), your Social Security number, and your spouse’s number if filing jointly. Be sure to list the correct county and municipality codes, which can be found in the official instructions. Select your filing status—single, married filing jointly, married filing separately, head of household, or qualifying widow(er)—ensuring it matches your federal return.
Include all taxable income sources for 2017. This covers wages, business income, retirement distributions, interest, dividends, and other taxable earnings. Suppose you have business income; complete Schedule NJ-BUS-1. Always use the “State Wages” amount from Box 16 of your W-2s rather than the federal figure when reporting wages.
If you qualify, you may exclude up to $40,000 in pension and retirement income for 2017, provided your total revenue was $100,000 or less. Part-year residents must prorate the exclusion. This deduction can significantly reduce your taxable income tax liability and may help increase your refund or lower the amount you need to pay in taxes.
List all eligible exemptions, including $1,000 for yourself, $1,000 for your spouse (if applicable), and $1,500 per dependent. Qualifying veterans can claim an additional $3,000 exemption. Ensure you have documentation to support your claims in case the department requests proof.
Deductions can include medical expenses over the threshold, alimony payments, property taxes, or 18% of rent paid (whichever is more beneficial). Keeping accurate records will help you substantiate your claims and avoid issues if your tax return is reviewed.
Use the tax table if your taxable income is under $100,000, or the tax rate schedules for higher incomes. Select the correct column for your filing status to calculate your taxes owed. This ensures you are paying the correct amount and prevents unexpected balances due.
List all payments made toward your 2017 taxes, including amounts withheld by employers and estimated payment installments. If eligible, claim the New Jersey Earned Income Tax Credit and other applicable credits. This step can reduce your balance due or increase the amount of your refund status.
These steps will help ensure your 2017 filing is accurate and processed without unnecessary delays. Whether you mail a paper return or submit your taxes online through the state’s enterprise services portal, completing each step carefully will improve your chances of a smooth process and timely results.
Even experienced individual taxpayers can make errors when filing a 2017 New Jersey tax return. Knowing the most common mistakes ahead of time can save you from delays, extra correspondence from the Treasury Division, or even penalties.
One of the most frequent errors is using the wrong income figure. New Jersey taxation rules require that you enter the “State Wages” amount from Box 16 of your W-2s, not the federal wages from Box 1. Using the federal number can lead to an incorrect taxpayer liability and trigger a follow-up letter from the department. Another issue is forgetting to attach all required forms—such as W-2s, 1099s, or relevant schedules—when you mail a paper return. Missing attachments can slow the process and affect your refund status.
Other common errors include reporting losses where not allowed, claiming ineligible deductions, or failing to sign and date your return. On joint filings, both spouses must sign; otherwise, the return is considered incomplete. Additionally, not verifying your bank account information for direct deposit can cause your refund to be delayed by weeks. If you’re making a payment, be sure to use the correct method—e-check, credit card, or check/money order—and follow the exact instructions provided on the New Jersey Division of Taxation’s forms page.
By avoiding these mistakes, you can help ensure that your taxes are processed efficiently and that your pay or refund is handled without unnecessary interruptions. Taking a few minutes to review your return before submitting it—whether online or by mail—can make a big difference in the overall filing experience.
For your 2017 New Jersey tax return, you can choose between electronic and paper filing. Each method has its benefits, and the best option depends on your comfort level, timeline, and access to the necessary tools. The Treasury Division of Taxation offers several official services to make the process easier for individual taxpayers.
Electronic filing is generally the fastest way to submit your return and receive your refund. Options include NJ WebFile, a free online system for eligible residents; NJ E-File, available through commercial tax software or authorized preparers; and NJ Fill’nFile, which lets you complete a PDF version of the NJ-1040 and submit it online. These platforms allow you to file taxes online, pay any balance due by e-check or credit card, and track your refund status without waiting for the mail. Filing electronically also reduces the chance of errors since built-in checks help flag missing information before submission.
If you prefer or need to submit a paper return, print the official NJ-1040 from the Division’s forms page or use the one mailed to you in your tax booklet. The mailing address depends on whether you expect a refund, have a balance due, or submit a zero-balance return. For returns with payment, include Form NJ-1040-V (Payment Voucher) and send it with your check or money order made payable to “State of New Jersey.” Using the correct address is essential to ensure your return reaches the department and is processed promptly.
When choosing between methods, consider how quickly you want your status updated and whether you’re comfortable using online platforms. While electronic filing is faster and more secure, mail remains a valid option for those who prefer to handle their taxes more traditionally. When done accurately, either method will meet state requirements and help you pay taxes or receive your refund without unnecessary delays.
If your 2017 New Jersey tax return shows you owe taxes, you have several ways to pay. The Treasury Division of Taxation provides secure electronic and traditional payment services. Paying the correct amount by the due date helps you avoid interest charges and penalties that can add up quickly.
Online payments are often the most convenient option. You can use an e-check to transfer funds directly from your bank account or pay by credit card through the state’s enterprise services portal. Both methods allow you to receive instant confirmation, making it easier to track your payment and refund status later if necessary. For detailed instructions on setting up and using these electronic payment methods, visit the New Jersey Division of Taxation EFT Payment Options page.
For those who prefer traditional payment methods, you can send a check or money order payable to “State of New Jersey.” Be sure to include Form NJ-1040-V (Payment Voucher) with your paper return or when mailing a payment separately. Always write your Social Security number and the tax year (2017) on the check to ensure the department credits it to the correct taxpayer account. Mailing addresses vary depending on whether you are including your return or just making a payment, so verify the correct address on the Division of Taxation’s forms page before sending.
Payments must be made by the original due date (April 15, 2019, for 2017 returns) to avoid penalties and interest. If you cannot pay the full amount owed, submitting your return on time still prevents a late-filing penalty, and you can arrange for a payment plan directly with the Division. Following the proper process—from choosing the right payment method to mailing your documents to the correct location—ensures your account is updated without unnecessary delays or a follow-up letter from the Treasury Division.
Once your 2017 New Jersey tax return is processed, you can check your refund status or confirm whether you still have a balance to pay. The Treasury Division of Taxation offers multiple services to help individual taxpayers monitor their accounts and stay informed about the process.
If you expect a refund, the fastest way to track it is through the Division’s secure Electronic Services Portal. You’ll need your Social Security number, the exact refund amount, and the tax year (2017) to access your status. The online tool provides the most up-to-date information and is generally quicker than waiting for a mailed notice. You can also call the Division’s automated phone system, which uses the exact details to provide your current status. Both options are available whether you filed electronically or submitted a paper return by mail.
Refund processing times can vary. Electronic filings with direct deposit are typically completed within a few weeks, while paper filings and check refunds may take longer. If you owe a balance, the Division will send a letter outlining your amount due, payment options, and a due date. You can then use an e-check, credit card, or traditional mail payment to resolve the balance. Checking your status regularly helps you stay on track and avoid penalties or interest for missed deadlines.
Before submitting your 2017 New Jersey tax return, use this checklist to ensure everything is accurate and complete. Reviewing your work can prevent delays in the process, protect your refund status, and reduce the chance of receiving a follow-up letter from the Treasury Division of Taxation.
Checklist:
Whether you submit your taxes online or by mail, reviewing this checklist ensures your taxpayer information is correct and helps your pay or refund reach the right place without unnecessary delays.
If you missed the filing deadline for your 2017 return, submit it as soon as possible. You may still be eligible for a refund, but the Treasury Division limits your claim time. Filing promptly also reduces penalties and interest on any unpaid taxes. Even if you can’t pay in full, send your return to start resolving your account.
You cannot e-file prior-year returns directly through the state’s current online system. The Treasury Division requires 2017 returns to be filed on paper using the NJ-1040 form. Download it from the official website, complete it accurately, and mail it to the correct address. Include all necessary attachments and use certified mail if you want proof of delivery for your records.
Commonly missed deductions include property tax deductions, medical expenses exceeding the allowable threshold, and charitable contributions to qualified organizations. Some individual taxpayers also overlook the rent deduction or credit and refunds for excess unemployment or disability contributions. Reviewing the NJ-1040 instructions carefully before filing can improve your refund status and ensure you take advantage of all credits and deductions available for the 2017 tax year.
The Treasury Division does not grant extensions for past-year returns, like 2017. Extensions must be requested by the original due date using Form NJ-630 or a federal extension request. For overdue filings, submit your completed return immediately. While the extension deadline is long past, timely submission can reduce further penalties and interest and establish compliance with New Jersey tax regulations.
Part-year residents can file jointly if they meet specific requirements. You must report only the income earned during your residency period in New Jersey and any applicable credits. Be sure to prorate deductions and exemptions. Tracking your refund status afterward is the same as for full-year residents—using either the online system or the New Jersey Division of Taxation phone service.
The Treasury Division follows the Military Spouses Residency Relief Act, which may exempt a civilian spouse’s income from New Jersey taxation under certain conditions. Active-duty members may retain their home-state residency for tax purposes. Always include required documentation with your return. If eligible, these rules can lower your taxable income, potentially improving your refund or reducing the balance you owe for 2017. For complete guidance on filing rules under the Military Spouses Residency Relief Act, see the NJ Division of Taxation Military Spouses Residency Relief Act page.
You should keep your 2017 return and supporting records for at least three years from the original filing date, as the Treasury Division can review past filings within this period. If you claimed a refund, hold onto your documents until your refund status is confirmed and processed. Keeping complete records also helps if you need to amend or respond to state inquiries later.
