Do I get additional tax benefits if I contribute to multiple ABLE accounts?

No, tax benefits for ABLE accounts and 529 plan accounts are aggregated for tax purposes by contributor, not by ABLE account or 529 plan. Anyone who contributes to one or more ABLE accounts or 529 plans with beneficiaries under the age of 21, can receive tax benefits up to the maximum allowable amount for that tax year. Contributions are deductible for Oregon income tax purposes up to annual limits. For 2016, the deductions for ABLE and 529 plan contributions are $4,620 for taxpayers filing jointly and $2,310 for single filers. The deadline for 2016 is April 15, 2017. For 2017, the deduction is $4,660 for taxpayers filing jointly and $2,330 for single filers.
