529 tax deductions

Contributions to a 529 plan are not deductible on your federal income tax return. For New York State income tax purposes, you can deduct contributions made to *any* state's 529 plan. As someone who works in New York and likely has New York source income, you would typically be eligible to claim this deduction on your New York non-resident income tax return. The maximum deduction is $10,000 for single filers or $20,000 for those married filing jointly. As a Connecticut resident, you can also deduct contributions made to *any* state's 529 plan on your Connecticut resident income tax return. Similar to New York, the maximum deduction is $10,000 for single filers or $20,000 for those married filing jointly. Therefore, you can deduct your contributions on both your New York and Connecticut state income tax returns, subject to their respective limits.
