Rhode Island levies a progressive state income tax with three brackets that top out at 5.99 percent. This calculator applies the official graduated thresholds, subtracts the standard deduction and personal exemptions, and shows your tax due along with effective and marginal rates.
How it works
Rhode Island taxes income in three slices. For 2024 the first roughly 73,450 dollars of taxable income is taxed at 3.75 percent, income up to about 166,950 dollars at 4.75 percent, and everything above 166,950 dollars at 5.99 percent. The same bracket thresholds apply to all filing statuses; Rhode Island does not double the brackets for joint filers.
Taxable income is computed as:
taxable = income − standard deduction − (exemptions × $4,950)
The standard deduction is about 10,550 dollars single or 21,150 dollars joint for 2024, and each exemption is worth about 4,950 dollars. Both phase out at higher incomes; this tool applies the headline amounts.
Example
A single filer with 90,000 dollars of income and one exemption subtracts the 10,550 dollar standard deduction and 4,950 dollar exemption, leaving 74,500 dollars taxable. Tax is 3.75% of 73,450 (2,754 dollars) plus 4.75% of the remaining 1,050 (50 dollars), about 2,804 dollars — an effective rate near 3.1 percent.
Notes
Rhode Island indexes its brackets, deduction, and exemption for inflation each year, and both the deduction and exemption phase out at higher incomes (the deduction reaches zero around 246,000 dollars of AGI). This simplified tool uses the 2024 headline figures and does not model the phase-outs. Estimate only, not tax advice — confirm at tax.ri.gov.
