Overview of Rhode Island State Income Tax for 2018

Rhode Island’s income tax system applies to residents, part-year residents, and nonresidents with income earned in the state. For the 2018 fiscal year, taxpayers must follow the Rhode Island Division of Taxation requirements to ensure compliance and avoid penalties. Understanding who must file, the applicable standard deduction and personal exemption amounts, and any changes to the law can help you prepare an accurate tax return.

Who Needs to File a Rhode Island Tax Return

You are required to file a Rhode Island income tax return if you meet any of the following conditions:

  • You are a full-year resident who must file a federal tax return. This includes individuals who lived in Rhode Island for the entire tax year.

  • You are a part-year resident who earned income in Rhode Island during any portion of the year.

  • You are a nonresident who earned wages, self-employment income, or other taxable income from Rhode Island sources.

  • You meet certain conditions where filing is required even without a federal requirement, such as when your Rhode Island income exceeds your personal exemption and standard deduction combined.

Income Thresholds, Standard Deductions, and Personal Exemptions

For the 2018 tax year, the standard deduction and personal exemption amounts were as follows:

  • Standard deduction amounts: $8,525 for single filers and married filing separately; $17,050 for married filing jointly and qualifying widow(er); and $12,800 for head of household.

  • Personal exemption amount: $4,000 for each eligible exemption.

  • Phase-out rules: If your modified federal adjusted gross income exceeded $199,000, your standard deduction and personal exemption were subject to a reduction under Rhode Island’s credit phase-out rules.

Filing Deadline for 2018 Returns

The original due date for 2018 Rhode Island personal income tax returns was April 15, 2019. Returns were considered timely if postmarked by that date. Late filing could result in a penalty of 5% of the tax due per month, up to a maximum of 25%. Late payments were subject to interest at 18% per year and an additional penalty of 0.5% per month on any unpaid balance.

Key Changes for the 2018 Tax Year

Several updates to Rhode Island’s income tax laws affected taxpayers in the 2018 fiscal year:

  • Pension and 401(k) modification: Qualified applicants could reduce their taxable income by up to $15,000 for eligible retirement income, including pensions, 401(k), 403(b), and annuities.

  • Increased earned income tax credit: The state’s credit increased to 15% of the federal earned income tax credit, up from 12.5% in previous years.

  • Property tax relief increase: The maximum tax relief credit rose to $350 for eligible taxpayers, providing greater assistance for homeowners and particularly renters.

  • Corporate minimum tax reduction: The annual corporate minimum tax and pass-through entity filing fee decreased from $450 to $400, lowering costs for small businesses.

Required Rhode Island Tax Forms and Schedules

Filing your Rhode Island personal income tax return for the 2018 fiscal year requires using the correct forms and schedules based on your filing status, income sources, and credit eligibility. Submitting the wrong form or omitting a needed schedule can delay processing and affect your refund or balance due.

Main Individual Forms

  • Form RI-1040: For full-year residents filing a standard Rhode Island tax return.

  • Form RI-1040NR: For nonresidents and part-year residents with Rhode Island income.

Supporting Schedules

  • Schedule W: Reports W-2 and 1099 wage and withholding information.

  • Schedule E: Used to claim personal exemptions.

  • Schedule M: Allows income modifications, such as pension adjustments.

  • Schedule U: Calculates use tax owed on out-of-state purchases.

Common Credit and Payment Forms

  • Form RI-1040V: Payment voucher for taxpayers sending a draft or money order.

  • Form RI-1040H: Claim form for eligible property tax relief. This can include homeowners and renters meeting income and residency criteria.

  • Forms for claiming a Rhode Island income tax credit, such as the earned or child tax credit, must be completed accurately with all required documentation.

Small Business Filing Forms

Sole proprietors typically report business income on Schedule C of their federal return, which flows to Form RI-1040. Businesses subject to the corporate minimum tax must ensure they meet the filing due date to avoid penalties and interest.

Step-by-Step Instructions to Complete Your 2018 Rhode Island Tax Return

Follow these steps in order. Each step uses plain language so first-time filers can move from documents to filing and payment without confusion.

  1. Complete your federal return first.
    Prepare your federal Form 1040 before starting state forms. Rhode Island calculations begin with your federal adjusted gross income, which reflects wages, dividends, and capital gains. For official state instructions, consult the 2018 Resident Instructions PDF: Rhode Island Division of Taxation (RI-1040).

  2. Gather your documents.
    Collect W-2s from each employer, 1099s, SSA statements, and records of taxes paid to other states. Bring proof of estimated payments and your Social Security number. Keep bank account details handy if you want a direct refund deposit.

  3. Confirm residency and filing status.
    Decide whether you are a full-year resident, part-year resident, or nonresident. Choose single, head of household, married filing jointly, or married filing separately. Joint filers should list both spouses’ information precisely as it appears on federal returns.

  4. Choose the correct forms and schedules.
    Use RI-1040 for residents and RI-1040NR for nonresidents or part-year residents. Add Schedule W for withholding, Schedule E for exemptions, Schedule M for income modifications, and Schedule U for use tax, if applicable.

  5. Enter identification and contact information.
    Provide your name, address, filing status, and Social Security number. Include a daytime phone number and an email address so the department can reach you quickly if clarification is needed.

  6. Calculate Rhode Island taxable income.
    Start with federal AGI, apply state modifications (for example, specific retirement income adjustments), subtract the standard deduction and personal exemptions, and arrive at taxable income. Use the 2018 tax tables to compute the preliminary tax.

  7. Claim credits you qualify for.
    Apply the credit for taxes paid to other states when the same income was taxed elsewhere. Review eligibility for Rhode Island’s earned income tax credit, the child tax credit, and any other income tax credit. Accurate entries help reduce your final bill.

  8. Report payments and reconcile your balance.
    Enter Rhode Island withholding from W-2/1099 forms, any estimated payments, and prior-year overpayments. Compare total payments to your calculated tax. If you owe, plan how to pay so that interest does not accrue.

  9. Choose your filing and payment methods.
    E-file for faster processing and direct deposits. If you prefer paper, sign the return and include the payment voucher (RI-1040V) with a check. If you mail your return, use the correct address for refunds versus payments to avoid delays.

  10. Submit, then monitor for updates.
    After filing, keep copies of all forms, worksheets, and receipts. Watch your bank account for a refund, or check for any letter from the department requesting additional information. Respond promptly to address any questions and complete the process.

Tip: Mark the original due date (April 15, 2019, for 2018 returns) in your notes. Late filings can lead to penalties and interest, so timely submission and payment protect your refund and limit extra costs.

How to File Your 2018 Rhode Island Tax Return

Filing your 2018 Rhode Island personal income tax return accurately is essential to avoid penalties, interest, and processing delays. Depending on their preferences and circumstances, taxpayers can choose between electronic filing (e-filing) and traditional paper filing. Regardless of the method, providing complete and correct information is essential to ensure your return is processed smoothly. Using the proper forms and attaching all required schedules will also help you receive your refund or confirm your balance due without issues.

Filing Your Rhode Island Personal Income Tax Return

You may file your personal income tax return electronically through approved software providers or with the help of a tax professional. E-filing is generally faster, reduces the chance of math errors, and allows direct deposit of any refund into your bank account. Paper filing remains an option for those who prefer physical records or need to submit additional documentation that is not supported by e-file. Use the correct mailing address for your specific filing situation when filing on paper.

Claiming the Earned Income Tax Credit

The Rhode Island earned income tax credit is a valuable benefit for qualifying taxpayers. For the 2018 fiscal year, it was worth 15% of the federal earned income credit and was fully refundable. This means eligible taxpayers could receive the credit as part of their refund even if they did not owe any state tax. To claim this credit, ensure your federal information is accurate, as it determines your eligibility and the amount you can receive.

Applying for an Income Tax Credit or Child Tax Credit

Rhode Island also offers other income tax credit opportunities, such as the child tax credit, which reduces your total tax liability if you have qualifying dependents. Accurate details on dependents, including Social Security numbers, are required to claim this benefit. The income tax credit and the child tax credit directly lower your tax owed, making them essential to review before submitting your return. Keep records to support your claims if the Rhode Island Division of Taxation requests verification.

Filing for a Rhode Island Tax Credit for Property Tax Relief

Property tax relief is available to eligible homeowners and renters through Form RI-1040H. This credit is based on factors such as income, age, and disability, and it can provide significant assistance to qualified applicants. You must submit proof of property tax payments or rent paid during the tax year to apply. Accurate documentation is essential to avoid delays or denials of your claim.

Including Property Tax Information in Your Return

Record the amounts paid during the tax year, including property tax details, in your return. This information may be used to determine eligibility for the property tax relief credit or other related benefits. Retain property tax bills, receipts, or municipal statements as evidence of payment. Keeping these records organized will make it easier to complete your return and respond to any inquiries from the tax department.

Understanding the Filing Due Date

The filing due date for 2018 Rhode Island personal income tax returns was April 15, 2019. Filing by the due date ensures you avoid late filing penalties, which can be substantial if your return is overdue. If you cannot meet the deadline, you may request an extension, but payment of any tax owed must still be made by the original due date. Meeting this deadline is essential to maintaining compliance and avoiding unnecessary costs.

Making a Payment

Paying your balance on time is essential in filing your 2018 Rhode Island tax return. The points below explain the key steps and considerations for making a payment.

  • Determine your total amount owed.


    • Calculate your balance based on Rhode Island tax law and the Internal Revenue Code.

    • Whether you owe a few dollars or a larger sum, paying by the due date prevents penalties and interest.

  • Accepted payment methods


    • Pay electronically through the state’s secure Online Tax Portal for faster processing.

    • Mail a check or money order payable to the Rhode Island Division of Taxation and the correct payment voucher.

    • Pay in person at the Division of Taxation office.

    • Use a credit card for convenience; the payment processor may charge a processing fee.

  • Choosing the right option


    • Electronic payments reduce the risk of delays and are popular with employees who prefer online management.

    • If you are mailing a payment, send it early enough to meet the deadline and avoid incurring late charges.

    • Always include the payment voucher to ensure the IRS and state apply your payment correctly.

  • Additional considerations


    • If the payment is associated with the sale or transfer of assets, ensure you maintain complete documentation for your records.

    • Ensure your account has sufficient funds before initiating payment to prevent returned transactions.

    • If discrepancies are found, the tax department may send a letter requesting proof or additional information, so retain all payment records.

Tracking Your Refund or Balance Due

Once you have filed your 2018 Rhode Island tax return, you can track your refund or confirm your remaining balance due through the Rhode Island Division of Taxation’s online services. This process helps you stay informed about your payment or refund status without contacting the office directly. If you are due a refund, providing accurate banking details allows the state to deposit your funds more quickly, often within a few weeks.

The calculation of any refund or balance due is based on your reported income, deductions, and credits under both state tax law and the Internal Revenue Code. If you owe even a small amount, paying promptly to avoid penalties and interest is essential. The Rhode Island Division of Taxation may also coordinate with the IRS when certain payments are involved, especially in cases where federal offsets apply.

If a payment is late or insufficient, the state can issue a penalty, and interest may be levied on the unpaid portion. For employees receiving a refund, the processing time can be shorter when direct deposit is selected instead of a paper check. If your return involves complex transactions, such as the sale of significant assets, you may need to provide documentation to confirm your calculations.

Keeping detailed records of your payments, revenue reports, and supporting paperwork will make responding easier if the tax department requests additional information. Monitoring your account regularly helps ensure that no unexpected issues arise and that your refund or balance due is handled correctly from start to finish.

Filing Extensions

If you cannot submit your 2018 Rhode Island tax return by the original deadline, you may request a filing extension. An extension provides additional time to send in your completed return, but it does not extend the time to pay any tax owed. You must still pay your estimated balance by the original due date to avoid penalties and interest.

Rhode Island Automatic Extension (Form RI-4868)

Rhode Island offers an automatic six-month extension when you file Form RI-4868. This form should be submitted by the original deadline and include your estimated payment. You can complete and submit it electronically or by mail. Detailed instructions are available on the Rhode Island Division of Taxation’s extension page.

Federal Extension Shortcut

If you file a federal extension (Form 4868) with the IRS and do not owe Rhode Island tax, you do not need to submit a separate state extension. Instead, attach a copy of your approved federal extension when you file your Rhode Island return.

Extension to File vs. Extension to Pay

It is important to remember that an extension to the file does not relieve you from paying on time. Any unpaid balance after the due date may be subject to penalties and interest charges. Paying on time helps prevent additional costs and keeps your account in satisfactory standing with the state tax department.

Final Filing Checklist

Before submitting your 2018 Rhode Island tax return, you must ensure that all of your filing is complete and accurate. A final review can prevent delays, reduce the chance of an IRS or Rhode Island Division of Taxation inquiry, and ensure you receive your refund or properly settle any balance due.

    • Check that your name, address, and Social Security number match your federal return.

Frequently Asked Questions (FAQs)

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

File your return as soon as possible to reduce penalties and interest. Rhode Island charges a late filing penalty of 5% per month, up to 25%, and interest at 18% annually on unpaid taxes. Even if you cannot pay in full, submitting your return stops the failure-to-file penalty and shows compliance with state filing requirements.

Can I e-file my 2018 Rhode Island return for free?

Yes. Rhode Island accepts e-filed returns, and some tax software providers offer free filing for eligible taxpayers based on income, age, or filing status. Check the state’s list of approved vendors to see if you qualify. E-filing helps reduce errors, speeds up processing, and allows for direct deposit, often resulting in a faster refund than mailing a paper return.

Which deductions or credits are most commonly overlooked?

Commonly missed credits include the Rhode Island earned income tax credit, the credit for property tax relief for eligible homeowners and renters, and the credit for taxes paid to other states. Taxpayers sometimes overlook modifications like the pension and 401(k) subtraction. Reviewing the Rhode Island Division of Taxation’s instructions and ensuring you meet eligibility requirements will help you claim all available benefits and reduce your final tax liability.

How do I request an extension to file my Rhode Island return?

You can request a six-month extension by filing Form RI-4868 and paying your estimated tax by the original due date. If you filed a federal extension and owe no Rhode Island tax, attach a copy of it to your state return instead. Remember, an extension gives more time to file, not to pay, so any unpaid tax after the due date may result in penalties and interest.

How do I claim credit for taxes paid to other states?

Use Schedule II on your Rhode Island return to calculate the credit for taxes paid to another state. This prevents double taxation on the same income. Attach a copy of the other state’s return and proof of payment. The credit is limited to the amount of Rhode Island tax that would have been due on that income, so review the instructions carefully to ensure you claim the correct amount.
