You can subtract up to $4,960 for Married Filing Jointly returns or up to $2,480 for all other returns for carried over contributions made to a 529 Oregon College Savings Network account prior to 2020.
If you made a contribution before January 1, 2020 that was more than your limit, you can carry forward the remaining contribution not subtracted over the next four years. Rollovers from other 529 plans into an Oregon 529 plan are considered new contributions and qualify for the subtraction. Keep a copy of your account statement with your tax records.
