Connecticut filing notes
Personal exemption credits phase out at higher incomes. A 'recapture' tax can push effective rates above stated brackets. Consider the high property tax when evaluating total cost of living.
Common mistakes: Not managing provisional income to reduce SS taxation; Taking large IRA distributions that push SS into taxable territory; Forgetting tax-exempt interest counts for provisional income.
