The Formula
Personal Exemption = $4,700 × (taxpayers + dependents) — phases out at AGI $248,250
RI Taxable Income = AGI − Std Deduction − Personal Exemptions
RI Tax = 3.75% on first $77,450 + 4.75% on $77,450–$176,050 + 5.99% above $176,050
Example: Single filer, $100,000 income
Std deduction: $10,550 | Personal exemption: $4,700
RI taxable: $100,000 − $10,550 − $4,700 = $84,750
RI tax: $77,450 × 3.75% + $7,300 × 4.75% = $2,904 + $347 = $3,251
RI effective rate: 3.25%
