                                    Underpayment of Oregon Estimated Tax

Oregon law generally requires you to pay tax as you earn or receive income during the year. Oregon employers and other payers 
are required to withhold tax when they pay you. You may be required to make estimated payments if the tax on your return after 
all credits and withholding will be $1,000 or more.
Your annual estimated tax payment may be paid in up to four installments. Unless an exception applies, underpayment interest is 
charged for each installment period when you underpaid or made late payments. Use these instructions to determine if you owe 
underpayment interest.
For more information about estimated taxes, see Publication OR-ESTIMATE.

Estimated payments at a glance
Required annual payment: The total amount of all tax payments, including estimated tax and withholding, that you must 
make in order to avoid being charged underpayment interest. Your required annual payment is the lesser of:
• Ninety percent (90%) of the tax after all credits shown on your 2022 Oregon return; or
• One hundred percent (100%) of the tax after all credits shown on your 2021 Oregon return (also known as “safe harbor”).
Annual estimated tax payment: Your required annual payment minus your withholding. This may be paid in up to four 
installments. You may also pay the entire annual amount by the due date for the first installment payment.
Required installment payment: The amount of estimated tax to be paid each installment period.
• Regular installment: The annual estimated tax payment amount divided by four.
• Annualized installment: An estimated tax payment based on income actually earned or received during an installment 
  period. Annualizing income may benefit taxpayers who don’t receive their income evenly throughout the year or are 
  part-year residents. Instructions for annualizing your income begin on page 6.

Example 3: Jill, a real estate broker, earns most of her commissions in the late spring and summer months, so she annual-
izes her income. Her AGI entered on line 1 is $15,000 in box 1A, $25,000 in box 1B, $65,000 in box 1C, and $85,000 in box 1D.
She’s deducting mortgage interest, property taxes, and medical expenses on Schedule OR-A. Her mortgage interest payment
averaged $300 per month, and she paid $1,600 in property tax in October. Jill made three payments toward a hospital bill
during the year: $1,200 in May, $8,000 in August, and $2,500 in November. Her Oregon itemized deductions total $8,400.
Her property tax deduction is less than the $10,000 limit, but she has to apply the AGI threshold to her medical expenses.
For each period, Jill applies the 7.5 percent threshold to her annualized AGI, but limits her annualized expenses to $11,700,
the actual amount she paid for the year ($1,200 + $8,000 + $2,500), so that she doesn’t deduct too much in any period.
Here is how Jill figures her itemized deductions for each column:
Column A:
Mortgage interest: ($300 x 3) $900
Property tax: 0
Medical expenses: 0
Total for Column A: $900
Jill enters $900 in box 11A. In box 13A, she enters $3,600 ($900 x 4).
Column B:
Mortgage interest: ($300 x 5) $1,500
Property tax: 0
Medical expenses:
Amount paid this period $1,200
Multiplier for Column B x 2.4
Annualized expenses $2,880
Medical expenses:
Lesser of annualized or $11,700 $2,880
AGI threshold:
AGI for Column B (box 1B) $20,000
Multiplier for Column B x 2.4
Annualized AGI $48,000
