Quartli — Quarterly Tax Estimator

Rhode Island Quarterly Estimated Taxes (2026)

Yes — self-employed workers in Rhode Island owe quarterly estimated taxes at both the federal and state level. You pay the IRS four times a year (April 15, June 15, September 15, January 15), and Rhode Island expects state estimated payments on its own schedule, which for most filers mirrors the federal dates. For 2026 planning, Quartli uses 4.75% — the Rhode Island marginal rate for a single filer with about $100k of taxable income under the official 2026 brackets. Your exact rate depends on income, filing status, and state-specific deductions.

Example: freelancer earning $80,000 in Rhode Island

A single filer with $80,000 of net self-employment income in 2026 (standard deduction, QBI deduction per Form 8995):

Federal self-employment tax$11,304
Federal income tax$5,344
Federal quarterly payment$4,162
Rhode Island state quarterly (≈4.75% planning rate)≈$950

Federal figures computed with official 2026 IRS brackets (Rev. Proc. 2025-32). The Rhode Island figure is a flat-rate planning approximation.
