Oregon 529 Plan Tax Benefit Calculator

Calculate your Oregon refundable tax credit for 529 college savings contributions.

Estimates the Oregon Education Savings Plan tax benefit, which is a refundable income tax credit (not a deduction) capped at 360 dollars for joint filers and phased by income, replacing the old contribution deduction Oregon ended in 2020.

Does Oregon offer a 529 deduction?

No longer. Oregon replaced its 529 contribution deduction with a refundable tax credit effective for tax year 2020. You now claim a credit rather than reducing taxable income, so the benefit no longer scales with your marginal rate.

Oregon changed how it rewards college saving in 2020. The state used to let you deduct 529 contributions from taxable income, which favoured high earners. It now offers a refundable tax credit instead — a flat-dollar benefit that is more generous to lower- and middle-income savers and is paid out even if you owe no Oregon tax. This calculator estimates that credit for contributions to the Oregon College Savings Plan.

How it works

The credit is computed as a percentage of your contribution, then capped:

  1. Contribution. Enter how much you will put into an Oregon 529 account this year.
  2. Income-based match rate. Oregon applies a sliding percentage based on your adjusted gross income (AGI). Lower-income households receive a higher match — for example a large share of the contribution — while higher-income households receive a smaller percentage.
  3. Apply and cap. The match percentage is multiplied by your contribution, then capped at the annual maximum: $180 for single filers and $360 married filing jointly.

Because the credit is refundable, the full amount benefits you regardless of your tax liability.

Tips and example

Suppose a married couple with $60,000 AGI contributes $2,000. Their income tier earns a match of, say, 25%, which would be $500 — but the credit is capped at $360 for joint filers, so they receive $360. A single filer contributing $1,000 at a 50% match tier would earn $500 of value but be capped at $180.

To maximise the benefit, contribute at least enough to hit the cap given your match rate. Note this tool models only the state benefit — 529 earnings also grow federally tax-free when used for qualified education expenses. Match percentages and caps are set by Oregon and can be indexed; verify the current figures before filing.
