Schedule OR-A Instructions
General information
Use Schedule OR-A to figure your Oregon itemized deduc-
tions using federal definitions and limitations, with the
modifications noted in these instructions. Generally, for
Oregon, youre allowed the larger of your itemized deduc-
tions or your standard deduction.
Note: Your Oregon standard deduction will be zero if you
are married filing a separate return and your spouse item-
izes, or if you are a nonresident alien.
If you itemize, you can deduct a part of your medical and
dental expenses, amounts you paid for certain taxes, inter-
est, gifts to charity, and certain miscellaneous expenses.
Dont include items that you deducted elsewhere on your
federal or Oregon tax return forms or schedules, such as
Schedule C, C-EZ, E, or F. In some cases, you may have to
add some deductions back or reduce some income items on
your Oregon return. See the Internal Revenue Service (IRS)
publications referred to in these instructions and Publica-
tion OR-17 for more information.
Medical and dental expenses
In general
You can deduct only the part of your medical and dental
expenses that exceeds 7.5 percent of the amount of your fed-
eral adjusted gross income on Form OR-40, line 7, or Form
OR-40-N or OR-40-P, line 29F.
Examples of medical and dental payments
you can deduct
To the extent you weren’t reimbursed, and with certain lim-
itations, you can generally deduct what you paid for:
Insurance premiums for medical and dental care, includ-
ing Medicare Parts B and D.
Prescription medicines and insulin.
Healthcare professionals, including medical doctors,
dentists, physical therapists, and psychologists.
Medical examinations, X-rays, laboratory fees, diagnos-
tic tests, and other services.
Hospital care and nursing help.
Ambulance service and other travel costs.
Nicotine cessation, medical weight-loss, and addiction
treatment.
Hearing aids, eyeglasses, wheelchairs, guide dogs, and
other medical aids.
Lodging costs and travel for treatment away from home.
Lactation supplies.
Examples of expenses you can’t deduct
Elective cosmetic surgery.
Over-the-counter medications.
Drugs that are illegal under federal law.
Funeral, burial, or cremation costs.
The above lists are not exhaustive. IRS Publication 502, Med-
ical and Dental Expenses, describes the types of expenses you
can and can’t deduct in greater detail. It also explains when
you can deduct capital expenses and special care expenses
for disabled persons. Note: You dont have to reduce your
expenses if you’re claiming the federal credit for business
or health coverage.
Whose medical and dental expenses
can be included?
You can include medical and dental bills you paid in 2021
for anyone who was one of the following, either when the
services were provided or when you paid for them:
Yourself and your spouse.
All dependents you are claiming on your Oregon return,
and any child you can’t claim as a dependent because of
the rules for children of divorced or separated parents.
Any person you could have claimed as a dependent on
your Oregon return except that their gross income for
2021 was $4,300 or more or they filed a joint return.
Any person you could have claimed as a dependent
except that you or your spouse (if filing a joint Oregon
return) can be claimed as a dependent on someone else’s
2021 return.
Deceased taxpayer. Certain medical expenses paid out of a
deceased taxpayer’s estate can be claimed on the deceased
taxpayer’s final return. See IRS Publication 502 for details.
Coordination with the Working Family
Household and Dependent Care (WFHDC) credit
Some medical expenses for the care of qualifying persons
may also qualify as expenses for purposes of claiming the
WFHDC credit. These expenses can be included in your
itemized deductions or be used for the WFHDC credit, but
they cant be used for both. See “Additions” in Publication
OR-17 for more information.
Lines 1 through 4
Line 1. Medical and dental expenses. Enter the total of
your medical and dental expenses, reduced by any pay-
ments you received from insurance or other sources.

Schedule OR-A Instructions
Don’t include:
• Payments that your insurance company paid directly to
the provider.
Amounts that were paid through an employer-sponsored
(cafeteria) plan, unless those amounts were included in
box 1 of Form W-2.
Expenses that youre using for the WFHDC credit unless
you also report any required add back.
Line 2. AGI. Enter the amount from Form OR-40, line 7, or

Line 3. AGI threshold. Multiply line 2 by 7.5% (0.075).
Line 4. Medical and dental expense deduction. Subtract
line 3 from line 1. If line 3 is more than line 1, enter 0.
Coordination with the special
medical subtraction
If you or your spouse turned age 66 by the end of the tax
year, and your federal AGI wasnt more than $200,000
($100,000 if your filing status is single or married filing
separately), you may qualify for the special Oregon medi-
cal subtraction. You’ll need the information from Sched-
ule OR-A, lines 1 and 4, when you figure your subtraction
amount. See “Special Oregon medical subtraction” in Pub-
lication OR-17 for more information.
Taxes you paid
In general
You may deduct certain state or local income taxes or foreign
income taxes you paid during the tax year, such as income
taxes paid to a state other than Oregon, mandatory contri-
butions to certain employment-related programs in other
states, and taxes on real or personal property located in the
United States that are based on the propertys value (known
as ad valorem tax). Income-based taxes paid to a local gov-
ernment within Oregon, such as Portlands Arts Tax, may
be deducted because they’re not paid to the State of Oregon.
Limitation on income and property tax
The total amount of income and property taxes you can
deduct cant be more than $10,000 ($5,000 if married filing
separately).
Examples of taxes you can’t deduct
Oregon income tax.
Charitable contributions claimed as payments of Oregon
income tax.
Income taxes paid to another state on which you’re bas-
ing an Oregon credit.
Oregon statewide transit tax.
Federal income tax.
Sales tax.
Tax on real property paid to a foreign country.
Social Security, Medicare, unemployment, or railroad
retirement tax.
Gift tax.
Estate tax, other than federal estate tax on income in
respect of a decedent (see below).
Customs duties.
Gasoline tax.
License fees.
Assessments for property improvements.
Taxes you paid for someone else.
Charitable contributions claimed as Oregon tax payments.
You cant deduct a charitable contribution for which you
received an Oregon tax credit as a payment of Oregon
income tax. See “Gifts to charity” and the “Credits” section
of Publication OR-17 for more information.
Federal income tax. You cant claim an itemized deduction
for federal income tax paid during the tax year. However,
see “Federal tax liability subtraction” in Publication OR-17
for more information.
Income taxes paid to another state. If youre claiming
a credit on your Oregon return for income taxes paid to
another state, you must reduce your deduction by the
amount of tax paid to the other state.
Credit and deduction—same year. If you claimed a credit
on an Oregon return for taxes you paid during this tax year,
you must reduce your deduction by the amount of the other
states tax liability or the amount youre deducting, which-
ever is less.
Example 1: Inga, an Oregon resident, paid $11,000 in
income tax to Maine and $12,000 in income tax to Arizona
this year. She’s claiming a credit for the taxes paid to Maine
on this year’s Oregon return. She had $13,000 in Maine
tax and $15,000 in Arizona tax withheld from her income
during the year, for total income taxes paid to a state other
than Oregon of $28,000 ($13,000 + $15,000). On Ingas Maine
return, her net tax liability is $12,000. She reduces her
Oregon deduction for taxes paid to Maine by $12,000. She’ll
report $16,000 ($28,000 – $12,000) on Schedule OR-A, line 5.
Credit and deduction—different years. You must reduce
this year’s deduction for taxes you paid to another state if:
• You claimed a credit for taxes paid to the other state on
an Oregon return for a prior year,
The credit was based on tax you owed the other state for
the year you claimed the credit, and
This year, you paid the tax that you owed the other state
for the prior year.
Reduce your deduction by the smaller of:
The other states tax for the year you claimed the credit, or
The amount of the other state’s tax for that year which
you paid this year.
The total amount of your reduction will equal the total
amount of tax on which your credit was based.
Example 2: Peggy is an Oregon resident. She owes $3,000 to
Iowa for 2021 tax on income that is also taxed by Oregon.
She’s claiming a credit on her Oregon return that is based
on her $3,000 Iowa tax liability. Peggy had $1,250 in tax
withheld from her Iowa income in 2021. Shes paying the
3
150-101-007-1 (Rev. 10-27-21)
Schedule OR-A Instructions
remaining $1,750 in April 2022 when she files her 2021
returns. Peggy’s deduction for tax paid to Iowa for 2021 is
the $1,250 in withholding, and if she itemizes in 2022, her
deduction will be the remaining $1,750. For 2021, her Oregon
itemized deduction for taxes paid to Iowa is reduced by
$1,250, the tax she’s deducting on which her credit is based.
If she itemizes in 2022, she’ll reduce her deduction for taxes
paid to Iowa by $1,750, the remaining portion of the tax on
which her 2021 credit is based.
See “Income taxes paid to another state” in Publication
OR-17 for details about the credit.
Sales tax. Oregon doesnt allow a deduction for sales tax
paid. Important: If you made the election on your federal
Schedule A to deduct sales tax paid instead of income tax
paid, you cant deduct income tax paid on your Schedule
OR-A. (ORS 316.821)
Lines 5 through 11
Line 5. State and local income taxes. Enter the total of the
state and local income taxes you paid to a local govern-
ment or to a state other than Oregon, reduced as explained
above for any credits you’re claiming for income taxes paid
to another state.
Note: If you deducted sales tax paid instead of income
tax paid on your federal Schedule A, you must enter 0 on
line 5.
Line 6. Real estate taxes. Enter the state or local taxes you
paid on real estate you own that wasn’t used for business,
but only if the taxes are assessed uniformly at a like rate
on all real property throughout the community, and the
proceeds are used for general community or governmental
purposes. See IRS Publication 530, Tax Information for Home-
owners, for more information.
Don’t include the following:
Taxes on real property located outside the United States
or its possessions.
Itemized charges for services to specific property or per-
sons (for example, a flat fee charged by the county for
mowing a lawn that has grown beyond the permitted
height).
Charges for improvements that tend to increase the
value of your property, such as sidewalk assessments.
Line 7. Personal property taxes. Enter the state or local per-
sonal property taxes you paid that were:
• Based only on the property’s value (ad valorem) and
Imposed on a yearly basis.
Line 8. Reserved.
Line 9. Total income and property taxes. Enter the total
of lines 5, 6, and 7. Dont enter more than $10,000 ($5,000 if
married filing separately).
Line 10. Other taxes. List the type and amount of other
deductible taxes that aren’t already included on lines 5, 6,
or 7.
Interest you paid
You may deduct the following interest on Schedule OR-A:
Home mortgage interest. Interest paid on a home
mortgage that is secured by your main home or sec-
ond home, including first and second mortgages and
refinanced mortgages, including mortgage points.
Dont include interest paid on home equity loans. See
IRS Publication 936, Home Mortgage Interest Deduc-
tion, for debt and income limits and other information.
Note: If you had to reduce your deduction on your fed-
eral return because you claimed the mortgage inter-
est credit, you may subtract the reduction amount on
Schedule OR-ASC or OR-ASC-NP. See “Federal tax
credits” in Publication OR-17 for more information.
Mortgage insurance premiums. Mortgage insurance
premiums are deductible as a form of interest for tax
year 2021. You may deduct premiums paid or accrued for
mortgage insurance on your main home or second home
if the amount on Form OR-40, line 7, or Form OR-40-N
or OR-40-P, line 29F isn’t more than $109,000 ($54,500 if
mar ried filing separately). If the amount on Form OR-40,
line 7, or Form OR-40-N or OR-40-P, line 29F is more than
$100,000 ($50,000 if married filing separately), use the
“Mortgage Insurance Premiums Deduction Work sheet”
in the instructions for federal Schedule A to calculate
your mortgage insurance premium deduction. See IRS
Publication 936 for limits and other details.
Investment interest. This is interest paid on money
you borrowed to buy property held for investment.
Your investment interest deduction is generally limited
to the income, after other expenses, from the invest-
ments. Investment interest expense that exceeds the
investment income may be carried forward to next year.
Note: If the interest is allocable to income that is exempt
from Oregon tax, you may have to modify the income
on Schedule OR-ASC or OR-ASC-NP. Unless an excep-
tion applies, if you are deducting investment interest,
you must complete federal Form 4952, Investment Interest
Expense Deduction. Keep a copy of this form with your
tax records; dont include it with your Oregon return. For
more information, limitations, and additional require-
ments, see IRS Publication 550, Investment Income and
Expenses, and the instructions for Form 4952. For more
information about income with related interest expense,
see Publication OR-17.
Lines 12 through 17
Line 12. Mortgage interest and points reported on Form
1098. Enter the home mortgage interest and points reported
to you on federal Form 1098, Mortgage Interest Statement.

who didnt provide you with a Form 1098. If the recipient
was the person from whom you bought the home, enter the
person’s name, address, and Social Security number (SSN)
(if an individual) or employer identification number (EIN)
on the dotted line next to line 13.

Schedule OR-A Instructions
Line 14. Points not reported on Form 1098. Points are shown
on your settlement statement. You may deduct points paid
to borrow money but not for other purposes. Points paid to
refinance a mortgage must be deducted over the life of the
loan. See IRS Publication 936 for more information.
Line 15. Enter the premiums you paid for mortgage insur-
ance provided by the federal Department of Veterans
Affairs, the Federal Housing Administration, the federal
Rural Housing Service, or private mortgage insurance.
Note: If the amount from Form OR-40, line 7, or
Form OR-40-N or OR-40-P, line 29F is more than $100,000
($50,000 if married filing separately), refer to the instructions
for mortgage insurance premiums, above, for guidance.
Line 16. Investment interest. Enter the interest you paid on
money you borrowed to buy property held for investment.
Use the amount you calculated using federal Form 4952, if
applicable.
Don’t include interest paid on money you borrowed to
buy bonds issued by the Commonwealth of Puerto Rico
or the territories of Puerto Rico, Guam, Samoa, or the
Virgin Islands. Income from these bonds isnt taxable
by Oregon.
If youre deducting interest paid on money you bor-
rowed to buy U.S. bonds, notes, or other obligations,
you’ll need to reduce your subtraction for this income
on your Oregon return. See “Interest and dividends on
U.S. bonds and notes” in Publication OR-17 for more
information.
You’ll have an addition on your Oregon return if you
have income from bonds and notes issued by another
state, or political subdivision of another state. The
income from these bonds and notes isnt subject to fed-
eral tax, but it is taxable by Oregon. However, you may
reduce your addition by the amount of related invest-
ment expense that you couldnt include in your federal
itemized deductions. See “Interest on state and local gov-
ernment bonds outside of Oregon” in Publication OR-17
for more information.
Gifts to charity
You can deduct contributions or gifts you gave to orga-
nizations that are religious, charitable, educational, scien-
tific, or literary in purpose, including organizations that
work to prevent cruelty to children or animals. See IRS
Publication 526, Charitable Contributions, for limitations
and other details.
Charitable contribution adjustment. This federal deduc-
tion is from the CARES Act and is for taxpayers who made
charitable contributions of up to $300 ($600 if married filing
jointly) and are not claiming federal itemized deductions
for tax year 2021. Note: If youre itemizing deductions for
Oregon, you can’t claim the subtraction on your Oregon
return. Instead include this deduction with any other chari-
table contributions you claim on Schedule OR-A.
Amounts you can deduct
Contributions can be in cash, property, or certain out-of-
pocket expenses you paid to do volunteer work for a chari-
table organization. Single gifts of $250 or more require a
written statement showing the amount of cash contributed,
description of any property you donated, and a description
and estimated value of any goods or services you received
in return. Be sure to keep records of all your contributions,
including pay statements if you made cash contributions
through payroll deduction, receipts, written statements
from organizations, and any appraisals or other required
documentation. Unless directed otherwise, keep all state-
ments and other documentation with your tax records; we
may ask to see them later. See IRS Publication 526 for AGI
limits and other restrictions, treatment of gifts for which
you received a benefit, and additional information.
Amounts you can’t deduct
In general. You cant deduct such things as political contri-
butions, dues paid to fraternal orders or similar groups, or
the value of services you performed or benefits you received
in connection with your contribution. For additional items
that cant be deducted, see IRS Publication 526.
Disqualified charities. If a charitable organization doesnt
spend at least 30 percent of its annual functional expenses
for program services, you must add back your contribu-
tions to that organization on Schedule OR-ASC or OR-ASC-
NP. See the Oregon Department of Justice website, www.
doj.state.or.us, for a list of organizations that don’t meet
Oregons spending requirement. See “Additions” in Publi-
c at ion OR-17.
Contributions for disaster relief
Certain contributions made for relief efforts following
a presidentially-declared disaster are subject to special
treatment. See IRS Publication 976, Disaster Relief, for more
information.
Coordination with Oregon tax credits
In general. If youre claiming an Oregon tax credit that is
based on contributions you made to a charitable organiza-
tion or fund, you must add back some or all of those contri-
butions if youre claiming them as an itemized deduction.
You must add back contributions you made to the follow-
ing if you include any amount as an itemized deduction
and youre claiming a credit for those contributions on your
Oregon return:
Oregon Production Investment Fund (Oregon Film &
Video Office, auction).
College Opportunity Grant Fund (Higher Education
Coordinating Commission auction).
University Venture Development Fund (various
Oregon universities).
Oregon IDA Initiative Fund.

Schedule OR-A Instructions
Exception: Contributions to the Child Care Fund. You
must add back only the portion of your contributions for
which you received a credit. For example, if you received
a tax credit for half of your contribution amount, you must
add back any portion of the tax credit amount that youre
deducting as a charitable contribution; you dont have to
add back the other half.
Don’t deduct any charitable contributions that you’re
claiming as a payment of Oregon income tax on your fed-
eral return.
See “Additions” in Publication OR-17 for more information.
Lines 18 through 21
Note: Limits to lines 18, 19, and 20 should be applied on
each line individually. With limits already applied, line 21
should be the true total of lines 18, 19, and 20. For limits, see
the IRS guidelines under “Charitable Contribution Deduc-
tions” on the IRS website or IRS Publication 526.
Line 18. Gifts by cash or check. Enter the total value of
the gifts you made in cash or by check, including unreim-
bursed out-of-pocket expenses.
Line 19. Gifts other than by cash or check. Enter the total
value of your contributions of property other than by cash
or check. For used items, such as clothing or furniture, you
may deduct their fair market value at the time you donated
them. Fair market value is what a willing buyer would
voluntarily pay a willing seller for the item. If the amount
of your deduction is more than $500 (before applying any
income limits), complete federal Form 8283, Noncash Chari-
table Contributions. Keep a copy of this form with your
Oregon tax records; we may ask for it later. For additional
requirements, see the instructions for Form 8283.
Line 20. Carryover from prior year. Enter contributions
that you couldnt deduct in an earlier year because they
exceeded that year’s limits. Your total contributions for this
year, including any carryover amount, cant exceed this
year’s limits.
Other miscellaneous deductions
You may deduct certain other items that arent deducted
elsewhere on the return or on other supporting schedules.
These miscellaneous deductions include claim of right
income repayments in excess of $3,000, gambling losses,
and federal estate tax on income in respect of a decedent.
(Note: See these topics below for amounts you may need
to add back on Schedule OR-ASC or OR-ASC-NP.) If youre
deducting a casualty loss or theft related to a presiden-
tially-declared disaster, include the amount here. Don’t
include miscellaneous deductions that are subject to the
2 percent AGI limitation, such as employee business
expenses or tax preparation fees. For more information
about these and other allowable deductions, along with a
list of items that arent deductible, see IRS Publication 529,
Miscellaneous Deductions.
Claim of right income repayments. In some cases, repay-
ments of more than $3,000 in income that you‘d included
in a prior year’s taxable income under a claim of right
may be included in miscellaneous itemized deduc-
tions. Oregon allows a credit for repayments over
$3,000 if the income was previously taxed by Oregon.
If you claim the Oregon credit, you must add back
your itemized deduction for the repayment on Sched-
ule OR-A SC or OR-ASC-NP. See the instructions for
Worksheet OR-CRC, Oregon Claim of Right Income Repay-
ment Credit, for more information.
Gambling losses. Generally, you may deduct gambling
losses up to the amount of your taxable winnings. How-
ever, Oregon doesnt tax winnings of $600 or less from a
single play or ticket from the Oregon Lottery. If youre sub-
tracting Oregon Lottery winnings on Schedule OR-ASC or
OR-ASC-NP, you’ll need to add back your gambling loss
deduction by the amount of Oregon Lottery winnings that
aren’t taxed by Oregon. See IRS Publication 529 for more
information about gambling losses, including recordkeep-
ing requirements. See “Additions” in Publication OR-17.
Federal estate tax on income in respect of a decedent (IRD).
You may deduct federal estate tax that you paid on IRD if
that income is taxed by Oregon. If only a portion of the fed-
eral estate tax is on income taxed by Oregon, you must add
back the tax on the IRD that Oregon doesnt tax. See “Addi-
tions” in Publication OR-17.
Line 22. Other miscellaneous deductions. List the type
and amount of your miscellaneous itemized deductions,
and enter the total on line 22.
Oregon itemized deductions
Line 23. Add lines 4, 11, 17, 21, and 22. Enter the total on
line 23 and on Form OR-40, line 16, or Form OR-40-N or
OR-40-P, line 37.
To ensure processing isn’t delayed on your Oregon return:
Include Schedule OR-A with your return when you file.
Ensure the tax year on Form OR-A is the same as the tax
year on your return.
