Overview of New York State Income Tax for 2018

Understanding how the 2018 New York State income tax rules apply to you is the first step in completing your return accurately. This section explains who needs to file, highlights significant changes from that year, and outlines the deadlines you must meet. These details help ensure you file the correct form, claim all eligible credits, and avoid penalties.

Who Needs to File a 2018 New York State Tax Return

You are generally required to file a 2018 New York State tax return if any of the following apply:

  • You were required to file a federal return for the 2018 tax year. If you filed a federal Form 1040, you likely needed to file a state return.

  • Your federal adjusted gross income plus New York additions was more than $4,000, or more than $3,100 if you were single and claimed as a dependent. This exception applies even if you did not file a federal return.

  • You had New York State, New York City, or Yonkers income tax withheld from your paycheck and wanted to claim a refund.

  • You are eligible for refundable or carryover credits, such as property tax credits, and you want to claim them.

Key Changes for the 2018 Tax Year

Tax rules changed in several ways for the 2018 filing year, which affected deductions and credits for many taxpayers:

  • New York Itemized Deduction—You could itemize deductions on your state return even if you claimed the standard deduction on your federal return.

  • Enhanced Child and Dependent Care Credit—The benefit increased for taxpayers with incomes between $50,000 and $150,000.

  • Empire State Child Credit Adjustments—This credit was calculated using pre-federal tax reform rules instead of updated federal amounts.

  • New Credits Introduced – These included the life sciences research and development credit, the farm donation credit to food pantries, and the Empire State apprenticeship credit.

Filing Deadlines for 2018 Returns

It is important to remember the deadlines so you can plan your filing and payments:

  • The original deadline was April 15, 2019, the last day to file your 2018 New York State return on time.

  • The extension deadline was October 15, 2019, the extended due date for those who filed Form IT-370.

  • An extension to the filing does not extend the deadline to pay your income tax. Any balance owed must still be paid by April 15, 2019, to avoid penalties and interest.

Required Forms and Schedules

When filing your 2018 New York State income tax return, it is essential to use the correct forms based on your residency status and tax situation. In addition to the main form, you may need to include supporting forms to report certain types of income, claim deductions, or apply for credits.

Main Form for Full-Year Residents – IT-201

  • Form IT-201 is required for anyone who was a full-year New York State resident in 2018 and needs to file a tax return.

  • This form reports all taxable income, calculates your income tax, and determines if you will receive a refund or owe a payment.

  • The official version of Form IT-201 can be downloaded from the New York State Department of Taxation and Finance website.

Forms for Nonresidents and Part-Year Residents

  • If you lived in New York for only part of 2018 or earned income while living outside the state, you must file Form IT-203.

  • This form ensures that your tax is calculated only on the portion of income earned in New York, which helps avoid paying more than you owe.

Common Additional Forms and Schedules

  • Form IT-2 must be filed if you received wages and had taxes withheld. This replaces the need to attach copies of your W-2 forms.

  • Form IT-196 allows you to itemize deductions for your state return, which may lower your taxable income if itemizing provides more savings than the standard deduction.

  • Form IT-225 is used to report income adjustments that are not included on the main form, such as specific additions or subtractions.

  • Form IT-201-ATT allows you to claim additional credits and report certain taxes not covered on Form IT-201.

  • Form IT-195 lets you direct some or all of your refund into a New York 529 college savings plan, helping you save for future education expenses.

  • Form IT-201-V is required when mailing a payment with your paper return to ensure the tax department processes it correctly.

Popular Credit Forms

  • Form IT-215 is used to claim the Earned Income Credit, which can reduce the income tax you owe or increase your refund.

  • Form IT-216 allows you to apply for the Child and Dependent Care Credit, which offers tax relief for qualifying childcare or dependent care expenses.

  • Form IT-213 is required to claim the Empire State Child Credit, which benefits families with qualifying children.

  • Form IT-214 lets you apply for the Real Property Tax Credit, which can lower your state tax based on eligible property taxes paid during the year.

Step-by-Step Instructions for How to File Your New York Tax Return 2018

Filing your 2018 New York State income tax return is easier when you break it into smaller, straightforward steps. The following process will guide you from gathering your documents to confirming your final calculations. Completing each stage carefully helps reduce mistakes, avoid delays, and ensure you receive any refund you are owed.

Step 1 – Gather Your Documents

  • Collect all W-2 forms from your employers to report wages and income tax withheld during the year.

  • Include any 1099 forms you received for interest, dividends, self-employment income, or retirement distributions.

  • To transfer the correct figures, have a copy of your federal tax return, including Form 1040 and any attached schedules.

  • Keep receipts for deductible expenses if you plan to itemize, as this documentation supports your claimed deductions.

  • Collect records of any estimated tax payments you made to New York in 2018, as these will help reduce your balance due.

Step 2 – Fill Out Personal Information

  • Enter your name exactly as it appears on your Social Security card to prevent processing delays.

  • Provide your complete address as of December 31, 2018, so any refund or correspondence is sent to the correct location.

  • Double-check your Social Security number and, if filing jointly, your spouse’s number to ensure accuracy.

Step 3 – Federal Return Information

  • Transfer your federal adjusted gross income from Form 1040 to the correct line on Form IT-201.

  • On the corresponding lines, enter other income items, such as wages, interest, business earnings, or unemployment compensation.

  • Keep your federal return available for reference while you complete this section, as you will need to match figures exactly.

Step 4 – New York Modifications

  • Add income that New York taxes but the federal government does not, such as interest from other states’ bonds.

  • Subtract federally taxable income not taxed by New York, such as interest from U.S. government bonds.

  • Utilize Form IT-225 to ensure these modifications are reported accurately.

Step 5 – Calculate New York Adjusted Gross Income

  • Add your federal adjusted gross income to any additions, then subtract any subtractions to determine your New York AGI.

  • Confirm your total before moving forward, since errors here will affect the rest of your tax return.

Step 6 – Choose Your Deductions

  • Select the standard deduction if it provides a greater benefit than itemizing; 2018 amounts varied by filing status.

  • Choose to itemize deductions if your allowable expenses, such as mortgage interest and property taxes, exceed your standard deduction.

  • Use Form IT-196 if you decide to itemize for New York purposes.

Step 7 – Calculate Your Tax

  • Use the tax tables if your income is $107,650 or less; otherwise, use the tax rate schedules.

  • Match your filing status to the correct chart to determine your New York State income tax.

  • The official tax tables are available on the New York State Department of Taxation and Finance website.

Step 8 – Apply Credits and Payments, Including Property Tax Credits

  • Claim any refundable or nonrefundable credits you are eligible for, such as the Earned Income Credit or Empire State Child Credit.

  • Apply for property tax credits using Form IT-214 if you qualify based on the property taxes you paid during 2018.

  • Enter the total New York tax withheld from your paychecks, any estimated payments made during the year, and any overpayments from the previous year.

Step 9 – Final Calculation

  • Subtract your total payments and credits from your tax to determine if you owe a balance or will receive a refund.

  • If your balance is due, arrange your payment method to prevent late fees and interest.

Step 10 – Common Mistakes to Avoid

  • Always check your math carefully before filing to prevent processing issues.

  • Make sure to include all necessary forms and schedules with your return.

  • Verify Social Security numbers for yourself, your spouse, and any dependents.

  • Sign and date your return before mailing or submitting it electronically, as unsigned returns will not be processed.

How to File Your 2018 New York Tax Return

Filing your 2018 New York State return can be done in two main ways: electronically or on paper. Your choice will affect how quickly your return is processed, how easily you can track your status, and whether you must mail documents. Understanding both methods before you begin is essential to choosing the best approach for your needs.

Electronic Filing (E-file)

E-filing allows you to submit your tax return directly through approved software or a professional tax preparer’s online system. This method lets you verify the state's receipt of your return and minimize possible errors. When using this method, most people anticipate faster refund arrival, particularly when they opt for direct deposit to a bank account.

When you create your e-file submission, you can set up payment or refund instructions in the same system. One key advantage is that you can open your filing session any time of the day or week, even on a Sunday, without needing to visit an office. The New York State Department of Taxation and Finance offers a free filing service for qualifying taxpayers on the official state tax website.

Paper Filing

If you prefer to send documents by mail, cannot use e-filing software, or need to include forms not supported by electronic systems, paper filing may be considered. When filing on paper, you must mail your return to the correct address based on whether a payment is enclosed. Be aware that sending a payment may involve a processing charge from your financial institution, depending on the payment method.

Many taxpayers choose e-filing instead of paper filing because mailed returns can take longer to process, sometimes up to two months. Additionally, removing any required schedules or forms from your package before delivery increases the risk of delays. Paper filing can take longer since you must organize your return before sending it.

Private Delivery Services

Some taxpayers prefer to use a private delivery service for added tracking and speed. While this can provide extra peace of mind, using a delivery company serving the approved state addresses for private carriers is essential. Filers needing to meet a close deadline in January or July often choose this method, particularly if they send corrected returns or pay an outstanding balance.

Payment Methods and Deadlines

Several secure options are available for paying any balance due on your 2018 New York State tax return. The correct method depends on how quickly you need the payment to process, your preferred level of convenience, and whether you want to handle it electronically or by mail. Understanding these choices helps you plan and avoid unnecessary penalties.

Online Payment Options

Making a payment online is often the fastest and most reliable method. You can log in to your New York State Individual Online Services account to submit payments using the following methods:

  • Bank transfer (ACH): This option allows you to pay directly from your checking or savings account with no additional fee.

  • Credit or debit card: This method is accepted but may incur a small processing fee from the payment processor.

  • Scheduled payments: You can view and manage these through your account, which is helpful if you want to plan and make partial payments before the deadline.

Payment by Mail

Some taxpayers still prefer to mail a payment. If you choose this option:

  • A check or money order should be made payable to “New York State Income Tax.”

  • Always write the last four digits of your Social Security number and “2018 Income Tax” in the memo line so it can be matched to your tax return.

  • Include the Form IT-201-V payment voucher to ensure proper processing.

  • Ensure the payment is mailed to the correct address in the official 2018 New York tax filing instructions.

Deadlines and Penalties

The original payment due date for the 2018 New York State tax return was April 15, 2019. This deadline applies even if you filed for an extension to submit your return. An extension only provides you more time to file paperwork; it does not offer you more time to pay what you owe. If your payment was submitted after the due date, the state would charge interest and late payment penalties, which can add to your balance quickly. These penalties are costly because they are based on the unpaid tax amount and the number of days past the deadline. 

This means that even a small balance can grow significantly if not paid for an extended period. In tax filing, staying ahead of deadlines is one of the most effective ways to reduce stress and avoid unnecessary costs. In other words, making your payment on time, whether online or by mail, helps you remain in good standing with the state and prevents additional charges from accumulating.

Tracking Your Refund or Balance Due

Monitoring your refund or balance after filing your 2018 New York State tax return helps you stay on top of your obligations and avoid unexpected issues. The state provides tools that make it easier to check your status and plan your next steps. Consistently checking your status can help you act quickly if corrections or additional payments are required.

Checking Your Refund Status

If you are expecting a refund, you can track its progress using the state’s online or phone-based services. You will need your Social Security number, filing status, and return refund amount. You can expect faster updates if you file electronically, as e-filed returns are processed faster than paper returns. Regularly checking your refund status ensures you know when to anticipate payment and helps you verify that there are no processing delays.

Viewing Your Balance Due

If you owe money, you can view your payment history and the remaining balance through your secure online account. Take note that updates to your balance may take a few days after making a payment, so allow for processing time before checking again. An accurate balance view can help you make timely payments and avoid additional interest or penalties.

Why Tracking Matters

These tools are essential because they confirm your return was received and allow you to catch any issues early. In tax filing, staying informed about your refund or balance due is one of the simplest ways to stay in control and avoid costly surprises. Tracking regularly during the filing season can give you confidence that your return is on track and processed correctly.

Final Filing Checklist

Before sending your 2018 New York State tax return, verifying that all required forms, attachments, and payment details are in order is essential. Reviewing your filing can help you avoid delays, prevent rejections, and ensure that your return is processed correctly the first time.

Confirm All Forms and Information

Before submission, make sure your return is complete and accurate. Missing or incorrect details can lead to processing delays or the need to amend your return later.

  • Confirm that you have filled out the correct version of Form IT-201 or IT-203 based on your residency status.

  • Verify that all Social Security numbers are correct for you, your spouse, and any dependents.

  • Double-check income figures and deductions against your records and supporting documents.

Attach all necessary forms and schedules to ensure a smooth and issue-free return process.

  • Include W-2 and 1099 forms for all sources of income reported on your return.

  • Add any payment voucher, such as IT-201-V, if you are mailing a payment with your return.

Finalize Payment or Refund Details

Completing the payment or refund section helps you avoid delays in receiving your funds or posting your payment.

  • Choose your refund method, such as direct deposit, and confirm that your bank account details are correct.

  • If making a payment, verify the amount and payment method before submitting.

  • Record your payment confirmation number or mailing receipt for future reference.

Keep Copies for Your Records

Retaining a complete copy of your return and attachments is integral to good recordkeeping.

  • Store both paper and digital copies of your filed return securely.

  • Keep your tax records for at least three years, or longer if you anticipate needing them for future financial or legal purposes.

Frequently Asked Questions (FAQs)

What should I do if I missed the April 15, 2019, deadline?

If you missed the deadline, file your 2018 New York State tax return promptly to minimize penalties and interest. Late filing can increase costs, especially if you owe money. Paying as soon as possible limits additional charges. If you expect a refund, there’s no penalty for filing late, but you must submit within three years of the original due date to claim it. Acting quickly helps minimize negative consequences.

Can I e-file my 2018 New York return for free?

You may qualify to e-file for free if your income meets New York State’s program limits. The Department of Taxation and Finance provides Free File options through approved software providers. Check eligibility requirements before you begin, as they change annually. Free e-filing can speed up refunds, provide confirmation that your return was received, and reduce errors compared to paper filing, making it a convenient choice for eligible taxpayers.

What deductions are most commonly missed?

Missed deductions often include property taxes paid, charitable contributions, medical expenses exceeding the income threshold, and certain education-related costs. Homeowners should also review eligibility for property tax credits, which can reduce state tax owed. Comparing your expenses against allowable deductions on Form IT-196 ensures nothing is overlooked. Taking time to review helps maximize your refund or lower your balance due, improving your overall tax outcome for the year.

How do I request a filing extension for my 2018 return?

For 2018, you could request an extension by filing Form IT-370 on or before April 15, 2019. This extended the filing deadline to October 15, 2019, but did not extend the deadline for payment. Any income tax owed still had to be paid by April 15 to avoid penalties and interest. Filing the extension on time helped avoid late filing penalties, even if you couldn’t finish your return.

Can I file jointly if my spouse moved mid-year?

You can generally file jointly if both spouses were New York residents for the entire year. If one spouse lived out of state the whole year, different rules apply, and separate returns may be required. In those cases, you might need Form IT-203 for part-year residents. Choosing the correct form ensures your tax return is accurate, avoids delays, and keeps your filing compliant with state law.

How do I report estimated tax payments?

List all estimated tax payments made to New York State for 2018 on the correct line of Form IT-201. Include quarterly payments and any overpayment from your 2017 return applied to 2018. Maintain records of amounts and dates in case the state requests verification. Correctly reporting estimated payments reduces your balance due, helps avoid underpayment penalties, and ensures your income tax records are complete and accurate.
