Check the Oregon tax return for the treatment year

Oregon tax credits can help with a treatment-year budget when your family meets each credit’s rules.

What it is

Oregon tax credits can help with a treatment-year budget when your family meets each credit’s rules.

A tax preparer can check Oregon’s refundable earned-income, young-child and work-related care credits as well as the separate disability credit. They have different age, income, filing and care-expense rules; a cancer diagnosis alone does not establish any credit.

Eligibility rules
  • The credit is for an Oregon filer with a dependent child who has a qualifying disability.
  • The additional disability credit requires a dependent age 21 or younger who qualifies for specified early-intervention or special-education services. Keep the annual eligibility statement and IEP or IFSP cover sheet. A cancer diagnosis or 504 plan alone does not establish this test. A preparer checks the final rules for your return’s year.
  • For tax year 2025, the Oregon Kids Credit is up to $1,050 per qualifying child age zero through five, for up to five children. Its own income and filing rules apply.
  • The Working Family Household and Dependent Care Credit uses its own work-related care-expense and income tests. A medical bill or cancer diagnosis alone does not establish qualifying care expenses. A preparer confirms the applicable year’s amount.
  • For tax years beginning in 2026, enacted SB 1507 increases Oregon’s earned-income credit to 14% of the federal credit, or 17% with a qualifying dependent under three. These replace the 2025 percentages of 9% and 12%.
What you get
  • Refundable credits for qualifying earnings, young children or work-related dependent care.
  • A separate, nonrefundable extra exemption credit for a qualifying child with a disability.
What the help includes
  • Oregon’s 2026 exemption-credit benchmark is $263. The additional qualifying-child disability credit is nonrefundable and follows its own dependency, disability and income rules. The current detailed instructions use a $100,000 adjusted-gross-income ceiling, regardless of filing status. A preparer confirms the final 2026 instructions before completing your return.
If you decide to apply
  1. Ask a tax preparer or free tax-assistance site which Oregon credits fit your family and tax year.
  2. Have your child's diagnosis date, relevant records, medical receipts and the prior return ready.

After you ask
  • The credit is claimed through the Oregon return rather than a separate benefits application.
Good to know

The disability credit has its own test; cancer alone does not meet it. The preparer checks.

Other details
  • The linked Oregon tax guide covers 2025. The return's tax year controls the credit rules.
  • The ordinary calendar-year 2026 filing date is April 15, 2027, subject to extension or relief. A preparer confirms the final 2026 instructions, including the indexed Kids Credit amount and income bands. The linked 2025 OR-17 is a prior-year reference.

Ask your social worker

“Which Oregon credits could fit our family for the treatment year? What would they change, what limits apply, and could you help us claim the ones we qualify for?”

Why I’m asking: I want to make sure the Oregon return reflects any credit our child's circumstances allow.

How to apply

First step: Ask whoever prepares the return about the additional exemption credit for a child with a qualifying disability.

  1. Bring the diagnosis date and medical receipts to whoever prepares the return.
  2. Ask specifically about the additional exemption credit for a child with a qualifying disability.

Official application / program page ↗

Where it starts: Claim it on the Oregon return; ask a preparer or a free tax assistance site.

What to gather

  • The diagnosis date
  • Medical receipts for the year
  • Last year's return

How long: At tax time.

What a yes looks like

An eligible nonrefundable credit reduces Oregon tax owed; it does not guarantee a larger refund.

What a no looks like, and the next move

Ask which part of the qualifying test was not met.

Watch out

  • The verified 2026 exemption-credit benchmark is $263. The additional qualifying-disabled-child credit is nonrefundable and requires the applicable dependency, age, educational-disability and income tests. The preparer should confirm the final 2026 instructions; cancer or a 504 plan alone does not establish eligibility.
