JOINT RETURNS Married individuals may make joint payments as if they were one taxpayer, in which case the liability with respect to the estimated tax shall be joint and several. No joint payments may be made if the mar- ried individuals are separated under a decree of divorce or of separate maintenance. If joint pay- ments are made, but the married individuals deter- mine their Rhode Island income taxes separately, the estimated tax, for such period, may be treated as the estimated tax of either individual, or may be divided between them, as they may elect. CHANGES IN INCOME Even though on April 15, 2026 you do not expect your tax to be large enough to require making esti- mated payments, a change in income may require you to make estimated payments later. HOW TO ESTIMATE YOUR TAX FOR 2026 Your 2026 estimated income tax may be based upon your 2025 income tax liability. If you wish to compute your 2026 estimated income tax, use the enclosed estimated tax worksheet. CREDIT FOR INCOME TAX OVERPAYMENT Your credit for income tax overpayment from your 2025 Rhode Island income tax return may be deducted from the first installment of your 2026 estimated tax, and any excess credit from succeeding installments.

The Rhode Island income tax law follows similar provisions of the Internal Revenue Code with respect to exceptions. Such charge on any unpaid installment shall be com- puted on the amount by which the actual pay- ments and credits applied to the tax are less than 80% of such installment at the time it is due. If it appears there was an underpayment of any installment of estimated tax, you may attach Form RI-2210 (if any of the exceptions apply) to your Rhode Island income tax return explaining why an additional charge should not be made. PENALTIES The law imposes penalties and interest charges for failing to pay estimated tax due or for making false or fraudulent statements.
