workers for tax years beginning on or after January 1,
2023, and before January 1, 2029. Taxpayers must apply
for the tax credit through the department. Note that this
credit can offset corporation minimum tax determined
under 317.090. Visit our website at ­www.oregon.gov/dor
for additional information.

Looking ahead
Credits

The credit is certified by Oregon department of Transportation (ODOT). The changes described here apply
to tax years beginning on or after January 1, 2024, and
before January 1, 2026.

Oregon Affordable Housing Lender’s Credit
(ORS 317.097)
Two separate bills amended this credit:
•	HB 2071 (2023) amended ORS 317.097 to allow financiers of limited equity cooperatives to claim the ORS
317.097 tax credit if the tax credit savings are passed on
to the tenants of the limited equity cooperative. This
change applies to tax years beginning on or after January 1, 2024.
•	SB 892 (2023) amended ORS 317.097 to apply to projects involving households earning 80 percent or less of
the area median income. Prior to the amendment, ORS
317.097 applies to projects involving households earning less than 80 percent of the area median income.

Estimated tax payments
Requirements
Oregon estimated tax payment requirements aren’t the
same as federal estimated tax payment requirements.
You must make estimated tax payments if you expect to
owe tax of $500 or more. This includes Oregon’s minimum tax. See ORS 314.505 to 314.525 and supporting
administrative rules.
If you don’t make estimated payments as required, you
may be subject to interest on underpayment of estimated
tax (UND). Refer to Form OR-37 if you have an underpayment of estimated tax.

Qualified semiconductor company research credit
HB 2009 (2023) allows a qualified semiconductor company to claim a tax credit based on research and
development expenses. The qualifying research and
development expenses are determined based on IRC 41.
Oregon allows a credit equal to 15 percent of the qualifying research and development expenses as determined
in IRC 41. The maximum amount of credit varies based
on employee numbers. A portion of the tax credit is
refundable if the taxpayer has fewer than 3,000 employees. The exact refund percentage depends on how many
employees the taxpayer has.

Payment due dates
Estimated tax payments are due quarterly, as follows:
•	Calendar year filers: April 15, June 15, September 15,
and December 15.
•	If the due date falls on a Saturday, Sunday, or legal
holiday, use the next regular business day.

Payment options

The new tax credit applies to tax years beginning on or
after January 1, 2024, and before January 1, 2030. The tax
credit will be certified by Oregon Business Development
Department (OBDD).

Important: For details about making payments with
your return, see “Filing checklist” below.

Sale of publicly supported housing credit

Estimated payments may be made by electronic funds
transfer (EFT), online, or by mail.

HB 2071 (2023) creates a tax credit for the sale of publicly
supported housing. The tax credit equals 2.5 percent of
the lesser of the sales price or appraisal if the owner held

EFT. You must make your Oregon estimated payments
by EFT if you’re required to make your federal estimated
payments by EFT. We may grant a waiver from EFT

payments if you’d be disadvantaged by the requirement
(ORS 314.518 and administrative supporting rules).

Corporation A should make four payments of $1,500 each
during the year. Because of its increased net tax, Corporation A will be subject to UND charges for the first and
second quarters. To avoid UND charges for the third and
fourth quarters, Corporation A must make timely payments of $3,500* for the third quarter and $1,500 for the
fourth quarter.

If you don’t meet the federal requirements for mandatory EFT payments, you may still make voluntary EFT
payments.
You can make EFT payments through Revenue Online or
through your financial institution. To learn more about
Revenue Online or to make an EFT payment, visit ­www.
oregon.gov/dor. If you pay by EFT, don’t send Form
OR‑20-V, Oregon Corporation Tax Payment Voucher.

*$1,000 for the first-quarter underpayment, plus $1,000
for the second-quarter underpayment, plus $1,500 for the
required third-quarter installment equals $3,500.

Filing information

Mail. If paying by mail, send each payment with a
Form OR-20-V, payment voucher, to: Oregon Department
of Revenue, PO Box 14950, Salem OR 97309-0950.

Who must file with Oregon?
Foreign and domestic insurance companies, including
home warranty companies (but not title insurers), that
are doing business in Oregon, or with income from an
Oregon source, are required to file Form OR-20-INS
[ORS 317.010(11), 317.122, and 317.650–317.665].

Include on your check:
•	Federal employer identification number (FEIN).
•	Tax year beginning and ending dates.
•	Contact phone.

Estimated tax payments’ worksheet

Note: Oregon follows the federal entity classification regulations. If an entity is classified or taxed as a
corpora­tion for federal income tax purposes, it will be
treated as a corporation for Oregon tax purposes.

(Keep for your records—don’t file with your payment.)
1. Oregon net income expected in
upcoming tax year.

1.

2. Tax on Oregon net income (see
Appendix B).

2.

3. Subtract tax credits allowable
in upcoming tax year. Tax
credits can’t be used to reduce
minimum tax.

3.

What form do I use?
Foreign and domestic insurance companies, including home warranty companies, are required to file
Form  OR‑20-INS, Oregon Insurance Excise Tax Return,
150‑102‑129. Title insurers aren’t required to file a
Form OR-20-INS. They file Form OR-20.
Insurance companies must file a Form OR-20-INS if
they’re doing business in Oregon. Insurance companies
with agents in this state whose only activity is solicitation are also subject to the excise tax. Companies having
income from an Oregon source, such as premiums from
existing policy holders, are doing business in Oregon
and must file Form OR-20-INS. Form OR-20-INS filers
are subject to the minimum tax.

4. Net tax (line 2 minus line 3).
4.
If the amount on line 4 is less
than $500, stop. You don’t have
to make estimated tax payments.
Caution: If your final tax
liability when you file your
return is $500 or more, you may
be subject to UND.
5. Amount of each payment.
(Divide line 4 by the number of
payments you need to make.
This is usually 4.)

Companies registered with the Insurance Division to do
business in Oregon, but who don’t actually do business
in the state during the tax year, and don’t have Oregon
source income, aren’t required to file Oregon Form OR20-INS and aren’t subject to the excise or minimum tax.

5.

If your expected net tax changes during the year, refigure your estimated tax payments using the Estimated tax
payments’ worksheet.

Filing requirements
Annual statement. Form OR-20-INS isn’t based on the
federal return. This form begins with “Net income from
the annual statement to the insurance commissioner.”

To avoid additional charges for UND, you must pay the
amount of any prior underpayment plus the amount of
the current required payment.

Tax year. All insurance companies required to file an
Oregon Insurance Excise Tax Return must file on a calendaryear basis and are subject to the minimum tax.

Example: During the year, Corporation A’s expected net
tax increased from $2,000 to $6,000. Corporation A made
timely first and second quarter estimated payments of
$500 before its expected net tax increased.
150-102-129-1 (Rev. 10-17-23) 	

Foreign and domestic domiciles (consolidated and separate returns). Foreign insurers and domestic insurers

2023 Form OR-20-INS Instructions

controlled by foreign insurers are required to file insurance excise tax returns on a separate basis. Unitary
domestic insurance companies (incorporated in Oregon) not controlled by foreign insurers incorporated
outside of Oregon must file consolidated returns if they
were included in consolidated federal returns. An interinsurance and reciprocal exchange and its attorney-infact may file consolidated returns.

audit report. Mail this separately from your current
year’s return.
If you don’t amend or send a copy of the federal or Insurance Division audit report, we have two years from the
date we’re notified of the change by the IRS to issue a
deficiency notice. To receive a refund, you must file a
claim for refund of tax within two years of the date of
the federal report.

Exempt

Amended returns

Surplus lines insurance companies and fraternal benefit
societies aren’t subject to the excise tax if exempt under
IRC §501(c)(8).

Oregon doesn’t have an amended return form for corporations. Use the form for the tax year you’re amending
and check the amended box. Always use your current
address. If your address has changed, don’t use your old
address or our system will revert your current address
to the old address.

Medicare & Medicaid
Income received from Centers for Medicare and Medicaid Services (CMS) Enrollees and Medicare Advantage
(MA) enrollees: 42 USC § 1395w-24(g) preempts imposition of Oregon minimum tax on income received from
CMS enrollees and MA enrollees. If you are paying minimum tax, exclude this income from your sales factor.
See Health Net Life Ins. Co. v. Dept. of Rev., TC 5371, Or.
Tax Ct., Reg. Div., May 3, 2021.

Fill in all amounts on your amended return, even if
they’re the same as originally filed. If you’re amending to change additions, subtractions, or credits, include
detail of all items and amounts, including carryovers.
If you change taxable income by filing an original or
amended federal or other state return, you must file an
amended Oregon return within 90 days of when the
original or amended federal or other state return is filed
(ORS 314.380). Include a copy of your original or amended
federal or other state return with your amended Oregon
return and explain the adjustments made.

E-file
If you’re required to e-file with the IRS, you’re also
required to e-file for Oregon (ORS 314.364). We accept
calendar year, fiscal year, short year, and amended electronic corporation tax returns utilizing the IRS Modernized e-file platform (MeF). Beginning January 2024, we’ll
accept e-filed returns for tax year 2023, and will continue
accepting returns for 2022 and 2021.

You may make payments online for your amended
return at ­www.oregon.gov/dor.
Don’t make payments for amended returns with EFT.
This also applies to e-filed amended returns. For paper
returns, you may pay online or include a check or money
order with your return. For e-filed returns, you may pay
online or send a check or money order separately. If you
mail your payment separate from your return, write
“Amended” on the payment and include a completed
Form OR-20-V with the amended box checked.

Your tax return software also allows you to make electronic payments when e-filing your original return.
Note: Your paper return may be rejected if you’re
required to electronically file your Oregon corporation
tax return, unless a waiver request has been approved by
us prior to the filing of the paper return.

Don’t amend your Oregon return if you amend the federal return to carry a net operating loss back to prior
years. Oregon allows corporations to carry net operating losses forward only.

If you’d like to request a waiver, send an email with
the FEIN, tax year, and reason you’re unable to e-file to
bus.electronicfiling@​
dor.oregon.gov, prior to paper-filing your return.

On the estimated tax payments line on your amended
Form OR-20-INS, enter the net excise tax per the original
return or as previously adjusted. Don’t include any penalty or interest portions of payments already made.

For a list of software vendors or for more information,
search “e-filing” at w
­ ww.oregon.gov/dor.

Federal and Insurance Division audit changes

If paying additional tax with your amended return, you
must include interest with your payment. Interest is figured from the day after the due date of your original
return up to the day we receive your full payment. See
“Interest rates.”

You must notify us if the IRS changes your federal return
or if the Insurance Division changes your Fire Marshal
tax or retaliatory tax for any tax year and the change
affects your computation of Oregon excise tax. If so, you
must file a Form OR-20-INS, checking the amended box,
and include a copy of the federal or Insurance Division

IRS (or you’re an owner of a tiered partner of such a
partnership), you may have to increase or decrease
your Oregon income as a result of the audit. Report an
increase in income using addition code 187 or report a
decrease in income using subtraction code 384, whichever is applicable. Use these codes even if another
code is assigned for the specific type of increased or
decreased income (ORS 314.733). Visit our website for
more information.

Line instructions
Income
Line 1. Life, accident, and health companies (from page
4, line 35 of the annual statement).
Line 2. Income, expenses, and other items attributable
to separate accounts. Enter amount from “Summary of
operations,” page 4, lines 5 and 8.1 of the annual statement for life insurance companies.

•	Decreases in certain reserves. These are changes
that haven’t been included in the computation of net
income from operations. Add decreases in man­datory
reserves that the insurer is required to maintain by
law or by rules or directives of the director of the
Department of Consumer and Business Services, other
than decreases that (a) are deducted in arriving at the
insurer’s net gain from operations, or (b) result from
net gains or losses, realized or unrealized, in the value
of the insurer’s property and investments.

Line 3. Subtotal (line 1 minus line 2).
Line 4. Fire, property, and casualty companies (from
page 4, line 20 of the annual statement).

°	 Life companies—Annual statement, “Summary of
operations,” page 4, line 44.
—	Also add decreases in reserves for policies and
obligations outstanding before the beginning
of the taxable year resulting from changes in the
basis and methods of computing such reserves
that are justi­fied by accounting and actuarial
practices applicable to or accepted by the insurance industry. Such prac­
tices are commonly
known as “reserve strengthen­ing” or “reserve
weakening.”
°	 Life companies—Annual statement, “Summary of
operations,” page 4, line 43.
°	 P&C companies—Annual statement, “Statement of
income,” page 4, line 37.

Line 7. Total (line 3 plus line 6).

Additions
Line 8. Total additions from Schedule OR-ASC-CORP,
Section A. The amount by which an item of income is
greater under Oregon law than as reported above on
lines 1 through 6, or the amount by which any allowable deduction is less under Oregon law, is an addition
on your Oregon return.
Use Schedule OR-ASC-CORP, Section A, to report the
amount and description code of each difference. Use the
description code from the list in Appendix A. The total
of all additions is entered on Form OR-20-INS, line 8.
Additions include:

•	Deferred gain recognized from out-of-state disposition of property acquired in an IRC §1031 or §1033
exchange. See ORS 317.327 regarding the computation
of the addition if deferred gain or loss wasn’t taken into
account in the computation of Oregon taxable income.

•	Charitable donations not allowed for Oregon. Donations to a charitable organization that has received a
disqualifying order from the Attorney General aren’t
deductible as charitable donations for Oregon tax purposes. Such organizations are required to provide a
disclosure to a donor to acknowledge this. The Attorney General will publish online and otherwise make
publicly available information identifying the charitable organizations receiving a disqualification order.
If you claimed a federal deduction, an addition must
be made on your Oregon return for donations to such
charitable organizations (ORS 317.491).

•	Depletion (percentage in excess of cost). Add the
federal deduction for depletion that is in excess of the
Oregon allowance for depletion (ORS 317.301).
•	Depreciation differences. If your Oregon depreciation
isn’t the same as the amount included in net income
from operations, the difference is a required modification on your Oregon return (ORS 317.301). Use Schedule OR-DEPR to determine the Oregon modification.

•	Claim of right income repayment adjustment when
credit’s claimed. Any deduction under IRC §1341
included in net income from operations must be
added back to income if your Oregon credit’s claimed
(ORS 317.388).

•	Federal income taxes. Add the amount of federal
income taxes deducted in computing net income from
operations. If a net refund of federal tax is shown on
the annual statement (due to an excess of refund for a
prior year over current year net tax), enter a negative
figure.

•	CPAR addition. If you’re an owner of a partnership
that was subject to a partnership-level audit by the

of Operations,” page 4, line 34.
°	 P&C companies: Use tax on ordinary income from
the annual statement, included in “Statement of
Income,” page 4, line 19.

Line 10. Total subtractions from Schedule OR-ASCCORP, Section B. The amount by which an item of income
is less under Oregon law than reported above on lines 1

description code from the list in Appendix A. The total
of all subtractions is entered on Form OR-20-INS, line 10.

•	Gain or loss on the disposition of depreciable property. Add the difference in gain or loss on sale of business assets when your Oregon basis is less than your
federal basis (ORS 317.356 and OAR 150-317-0420).

•	Individual Development Account credit. Donations
deducted from net income from operations must be
added back to federal taxable income if the Oregon
credit’s claimed [ORS 315.271(2)].

•	Amortization of past service credits. Subtract the
amortized portion of contribution for past service
credits made to qualified plans and exempt employee
trusts. The subtraction is for amounts not deducted
in the computation of net gain from operations in
the annual statement. There’s no explicit item in the
annual statement.

•	IRC §631(a) treatment of timber isn’t recognized by
Oregon. Both beginning and ending inventories must
be adjusted for IRC §631(a) gain. For Oregon purposes,
there’s no taxable event until actual sale (ORS 317.362).

°	 P&C and life companies—See note(s) in the NAIC
annual statement about retirement plans.

•	Opportunity Grant Fund (auction). Any federal deduction for contributions for which an Opportunity Grant
Fund tax credit certification is made must be added to
federal taxable income (ORS 315.643).

•	CPAR subtraction. If you’re an owner of a partnership that was subject to a partnership-level audit by
the IRS (or you’re an owner of a tiered partner of such
a partnership), you may have to increase or decrease
your Oregon income as a result of the audit. Report an
increase in income using addition code 187 or report a
decrease in income using subtraction code 384, whichever is applicable. Use these codes even if another
code is assigned for the specific type of increased or
decreased income (ORS 314.733). Visit our website for
more information.

•	Oregon production investment fund. Add back the
amount of contribution for which a tax credit certification is made that’s included in net income from operations as a deduction (ORS 315.514).

exchanges of assets, including non-admitted assets
that weren’t included in net income from operations.

•	Deferred gain recognized from out-of-state disposition of property acquired in an IRC §1031 or §1033
exchange. See ORS 317.327 regarding the computation
of the subtraction if deferred gain or loss wasn’t taken
into account in the computation of Oregon taxable
income.

•	State income taxes (all jurisdictions). Per ORS 317.655
include only the amount of state income taxes (including Oregon minimum tax) included in the following
amounts on the annual statement:

•	Depletion. Subtract the Oregon allowance for depletion that is in excess of the federal deduction for depletion (ORS 317.374).

°	 Life companies: Annual statement, included in
“General expenses,” page 11, exhibit 3, lines 3, 4, and
6, column 5.
°	 P&C companies: Annual statement, included in
“Underwriting and investment exhibit,” page 11,
lines 20.1 and 20.4.

•	University venture development fund contributions.
Add to income the amount of contributions deducted
in net income from operations and used to calculate
the University Venture Fund Contribution credit taken
on your Oregon return (ORS 315.640).

•	Film production labor rebate. Subtract the amount

when your Oregon basis is greater than your federal
basis (ORS 317.356).

Line 16. Minimum tax. The minimum tax for C corporations and insurance companies doing business in Oregon
is based on Oregon sales. Use the table in Appendix B.

•	Increases in certain reserves. Subtract increases in
reserves described in the instructions for additions.

•	Consolidated returns: the minimum tax is based on
Oregon sales of the affiliated group of corporations filing an Oregon return. One minimum tax applies to the
affiliated group filing the consolidated return, not to
each individual affiliate included in the consolidated
return doing business in Oregon.
•	The minimum tax isn’t apportionable for a short tax
year (except a change of accounting period).

•	Marijuana business expenses. ORS 317.363 allows
Oregon taxpayers filing a corporate excise or income
tax return to deduct business expenses otherwise
barred by IRC §280E if the taxpayer is engaged in marijuana-related activities authorized by ORS 475C.005 to
475C.525, or ORS 475C.700 to 475C.919.
•	Psilocybin business expenses. ORS 317.363 allows
Oregon corporation excise and income tax filers to
subtract certain business expenses otherwise barred
by IRC §280E if the corporation is engaged in psilocybin-related activities authorized by ORS 475A.210 to
475A.722, the Oregon Psilocybin Services Act. Use subtraction code 385 on Schedule OR-ASC-CORP.

Nonapportioned returns. Domestic insurance companies doing business only within Oregon can calculate
Oregon sales by adding the following:
•	Direct premiums;
•	Annuity considerations; and
•	Finance and service charge.
Apportioned returns. C corporations and insurance
companies doing business in more than one state that
apportion business income for Oregon tax purposes, use
the Oregon sales amount from line 22(a) on Schedule
OR-AP, part 1.

•	Realized losses. Realized losses on sales or exchanges
of assets, including non-admitted assets that weren’t
included in net income from operations.
Line 11. Income before net loss deduction (line 9 minus
line 10).

Line 17. Tax (greater of line 15 or line 16). Oregon tax is
the greater of total calculated tax or minimum tax.

Line 12. Net loss deduction.

Line 18. Tax adjustment for installment sales interest.
If you owe interest on deferred tax liabilities with respect
to installment obligations under ORS 314.302, enter the
amount of interest as a positive number. Include a schedule showing how you figured the interest.

•	Enter the deduction on line 12 if substitute “utilized”
only by Oregon. Enter as a positive number.
•	Enter the deduction on Schedule OR-AP, part 2, line 10a
if substitute “utilized” both in Oregon and another state.
•	Include a schedule showing your computations.
•	The Oregon deduction is the sum of unused net losses
assigned to Oregon for preceding taxable years.
•	A net operating loss carryforward is required to be
reduced by the entire Oregon taxable income of intervening tax years [ORS 317.476(4)(b)].
•	Insurers may carry net losses forward up to 15 years.
•	Oregon doesn’t allow net losses to be carried back.
•	The total net loss deduction on a consolidated Oregon
return is the sum of the net losses available to each
of the corporations subject to the limitations in ORS
317.476 and supporting administrative rules (ORS
317.665).

Line 19. Tax before credits (line 17 plus line 18).

•	100 percent late pay and late filing penalty. Include
a penalty payment of 100 percent of your unpaid tax
if you don’t file returns for three consecutive years by
the original or extended return filing due date of the
third year. A 100 percent penalty is assessed on each
year’s tax balance.

If your current year corporation tax liability, including the
minimum tax, is less than $500, you don’t need to make
estimated payments. Don’t complete this form. However,
this provision doesn’t apply to a high-income taxpayer. A

Special instructions. If you owe a penalty or interest
and have an overpayment on line 29, and your overpayment is less than total penalty and interest, then fill in
the result of line 33 minus line 29, on line 34.

Interest accrues on any unpaid tax during an extension
of time to file.

Line 36. Amount of refund to be credited to estimated
tax. You may elect to apply part or all of your refund
to your next year’s estimated tax payments. Fill in the
amount you want to apply. Your election is irrevocable.

Interest will increase by one-third of 1 percent per month
(4 percent yearly) on delinquencies if:
•	You file a return showing tax due, or we assessed an
existing deficiency; and
•	The assessment isn’t paid within 60 days after the
notice of assessment is issued; and
•	You haven’t filed a timely appeal with us.

Elected amounts that are attributable to estimated tax
payments received prior to the following year’s first
quarter estimated tax due date, will be applied as a
timely first quarter installment of the following year.
Elected amounts attributable to payments received after
the following year’s first quarter estimated tax due date,
will be applied to the following year’s estimated tax
account as of the date the payment is received. See ORS
314.515 and OAR 150-314-0302.

Line 32. Interest on underpayment of estimated tax
(UND). You must make quarterly estimated tax payments if you expect to owe $500 or more in tax. This
includes Oregon’s minimum tax. Oregon charges UND if:
•	The quarterly payment is less than the amount due for
that quarter; or
•	We receive the quarterly payment after that quarter’s
due date; or
•	No quarterly payments are made during the year and
the final tax debt is $500 or more.

Line 37. Net refund (line 35 minus line 36).

Oregon Corporation Form OR-20-INS
Alternative apportionment
Please read carefully. This information is not the same for all tax programs.
Oregon law allows taxpayers to request an alternative method of apportionment using the instructions
below. Uniform Division of Income for Tax Purposes Act
(UDITPA) taxpayers filing under ORS 314.605 to ORS
314.675, as well as insurers, and taxpayers filing under
ORS 314.280, must use this procedure to apply for alternative apportionment.

Note: Taxpayers filing amended returns for 2015 or prior
must use the form year corresponding to the tax year
even though there’s no alternative apportionment checkbox on the return. Clearly identify that you’re requesting
alternative apportionment by writing the words “Alternative apportionment request” at the top and adhere
to all other requirements. Determinations to amended
returns may take longer to process.

Administration

Method 2 —Alternative apportionment petition
submitted separately from your original or amended
return
•	Your written petition must have the title “Alternative
apportionment request.”
•	We will not rule on your alternative apportionment
request until you file your original or amended return
using standard apportionment provisions.
•	Your original or amended return, for which the written petition requests alternative apportionment, must
use standard apportionment provisions.
•	Mail your petition to: Oregon Department of Revenue, Corporation Section, 955 Center St NE, Salem OR
97301-2555.

We will review the alternative apportionment request
and issue a decision letter.
If your alternative apportionment petition is denied, you
may appeal the denial of your petition to Oregon Tax
Court as provided in ORS 305.275.
If your alternative apportionment petition is approved,
you may amend your returns within the normal statute
of limitations. The approval of your petition will remain
in effect unless and until we revoke it during audit or
you file a new petition and receive our approval of the
new proposal.
Allow at least 6 months for us to make a determination.
Also, note that all petitions for alternative apportionment may result in additional review and documentation requests.

Both methods of petition
•	The petition must be signed by the taxpayer or the taxpayer’s representative.
•	You must use standard apportionment provisions to
complete your original or amended return while the
department rules, in writing, on your request for alternative apportionment.
•	In the case of a UDITPA taxpayer, the petition must
fully explain the ext
