Rhode Island tax guide
Rhode Island's low $250 threshold means most self-employed residents will need to pay during the year.
Published by Cadus Labs LLC · Last updated November 9, 2026 · How we write these guides
Based on the Rhode Island Division of Taxation's 2026 Form RI-1040ES and other guidance from the state's tax agency.
You have to pay estimated tax if it can reasonably be expected to be $250 or more above any credits allowed against the tax.
The form is Form RI-1040ES, and you can generally pay online instead of mailing it.
| Payment | Due |
|---|---|
| First payment | April 15, 2026 |
| Second payment | June 15, 2026 |
| Third payment | September 15, 2026 |
| Fourth payment | January 15, 2027 |
You can skip the January payment if you file your 2026 return by February 15, 2027 and pay the full balance.
Wherever you live, self-employed income is subject to federal income tax and self-employment tax. A single filer with $60,000 of net profit and no other income owes about $12,037 in federal tax for 2026, or 20% of profit, before any state or local tax.
Federal estimated payments are due April 15, June 15, and September 15, 2026, and January 15, 2027. Use our 1099 tax calculator to run your own numbers.
