It’s too late, right? Not if you live in Oregon. In Oregon (and several other states) you can make a state-tax-deductible contribution to your 529 plan up until you file your 2014 taxes. If you do make a contribution in the first part of 2015, it’s generally best to take the deduction for 2014. Not only do you get the tax benefit sooner, but you leave your 2015 deduction available too. Remember, you can carry forward excess contributions, but you cannot apply them retroactively to past years in which you didn’t make the maximum.
