Rhode Island Estimated Tax Payments (2026)

Do you have to pay estimated taxes in Rhode Island?

Yes. If you're self-employed in Rhode Island and expect to owe $250 or more in Rhode Island income tax for 2026 after withholding, you must make quarterly estimated payments to the Rhode Island Division of Taxation. That is below the federal $1,000 threshold, so most part-time self-employed people owe them too. Rhode Island taxes income at graduated rates up to 5.99%.

When are Rhode Island estimated taxes due in 2026?

Rhode Island's 2026 quarterly payments are due April 15, June 15, September 15, and January 15, in four equal installments, on the same calendar as your federal payments.

• Q1, April 15, 2026

• Q2, June 15, 2026

• Q3, September 15, 2026

• Q4, January 15, 2027

How much should you set aside for Rhode Island estimated taxes?

Plan to set aside 20% to 25% of your net self-employment profit to cover federal and Rhode Island taxes combined, then confirm the exact amount with the calculator above. On $50,000 of net self-employment profit, federal self-employment tax alone is about $7,065 (15.3% on 92.35% of your earnings). On top of that you'll owe about $2,667 in federal income tax and about $1,126 in Rhode Island income tax, for a total of about $10,858, or 22% of your profit.

How do you avoid a Rhode Island underpayment penalty?

To avoid a Rhode Island underpayment penalty, pay the smaller of 80% of your 2026 Rhode Island tax or 100% of your 2025 tax, in four on-time installments. Rhode Island has no higher bar for high earners. Paying the full amount late doesn't help; each installment has to be on time. You can estimate a federal underpayment penalty here.

What deductions lower your Rhode Island estimated taxes?

Because estimated taxes are based on your net profit, every business write-off you claim lowers what you owe each quarter. Common deductions for 1099 workers, reported on Schedule C, include the home-office deduction, car mileage, phone and internet, software, and supplies. Some federal deductions carry over. Because Rhode Island starts with the income on your federal return, three deductions you take there also lower your Rhode Island tax: half of your self-employment tax, self-employed health insurance premiums, and self-employed 401(k) contributions. The federal Qualified Business Income (QBI) deduction can remove up to 20% of your qualified business income from your federal taxes, but Rhode Island doesn’t allow it, so it doesn’t lower your Rhode Island tax.

Do self-employed people in Rhode Island owe local or other taxes too?

Not usually. Rhode Island has no local income tax. If you form an LLC, though, it owes a $400 annual charge to the Division of Taxation every year, filed on Form RI-1065 by March 15, even if you're the only owner.

How to file quarterly taxes in Rhode Island

Filing quarterly in Rhode Island means two separate payments each period: one to the IRS for federal tax, and one to the Rhode Island Division of Taxation for your state taxes. Here’s how to do it.

1. Confirm you need to pay. You owe estimated payments when tax isn’t withheld from enough of your income — 1099 or freelance work, investment income, or other untaxed income. Federal and Rhode Island run separate tests: the state generally requires estimated payments if you expect to owe $250 or more in Rhode Island tax after withholding and credits, subject to its safe-harbor rules.
2. Calculate your federal estimate. Use the Form 1040-ES worksheet (or tax software). Estimate your full-year income, add your federal income tax and self-employment tax, subtract anything already withheld from a paycheck, and split the rest across the year. The estimate at the top of this page gives you a starting number.
3. Calculate your Rhode Island estimate separately. Work out your Rhode Island amount on its own using Form RI-1040ES. Don’t just send part of your federal payment to the state — the Rhode Island calculation is separate, based on your Rhode Island income tax, credits, and any Rhode Island withholding.
4. Pay the IRS. Pay through IRS Direct Pay (or EFTPS) and choose the estimated tax / Form 1040-ES option. Select tax year 2026 and save the confirmation number. This money counts only toward your federal taxes.
5. Pay Rhode Island separately. Make a second payment to RI Taxation Portal and select the Form RI-1040ES estimated payment for 2026. Save that confirmation too. This money counts only toward your Rhode Island taxes.
6. Repeat on each deadline. For 2026, federal estimated payments are due April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. Rhode Island uses those same four dates.
