When you are browsing Medford homes for sale, the “Estimated Monthly Payment” on real estate apps often feels like a moving target. In most states, property taxes are a simple percentage of the purchase price. However, moving to Southern Oregon introduces you to one of the most unique and complex property tax systems in the United States.
Because of two landmark constitutional amendments—Measure 5 and Measure 50—the amount you pay isn’t just based on what your home is worth today. Instead, it’s a calculation involving decades of legislative history, local bond measures, and specific neighborhood “ratios.”
This deep dive serves as your ultimate Oregon Property Tax Calculator for Jackson County, providing the regulatory context, local rates, and hidden exemptions every first-time homebuyer needs to know.
Key Takeaways
- The 3% Growth Cap: Under Measure 50, your “Assessed Value” (the number you’re actually taxed on) cannot grow by more than 3% per year for existing homes.
- Real Market Value (RMV) vs. Assessed Value (AV): You are taxed on the lesser of the two. In a rising market, your AV is often 30–40% lower than your home’s actual resale value.
- No “Reset” on Sale: Unlike California’s Proposition 13, your property taxes do not “reset” to 1% of the purchase price when you buy a home in Oregon. You inherit the previous owner’s tax base.
- Medford Tax Rates: For 2026, the combined tax rate for the City of Medford remains roughly $14.00–$15.00 per $1,000 of Assessed Value, depending on your specific school and fire district.

The Foundation: Measure 5 and Measure 50
To understand your tax bill, you have to understand the “Oregon Tax Revolt” of the 1990s. Before this, Oregon functioned like most states: if your home value doubled, your taxes doubled. Measures 5 and 50 changed that forever.
Measure 5 (The Rate Limit)
Passed in 1990, Measure 5 set strict limits on the total tax rate that can be applied to a property’s Real Market Value. It split taxes into two categories:
- Education: Limited to $5.00 per $1,000 of RMV.
- General Government: Limited to $10.00 per $1,000 of RMV.
If the combined local rates exceed these limits, a process called “Compression” occurs, where the tax bill is legally reduced to meet the cap.
Measure 50 (The Value Limit)
Passed in 1997, Measure 50 was the “game changer.” It decoupled taxes from market value entirely. It created a “Maximum Assessed Value” (MAV) for every property, set at 90% of its 1995 levels.
- The 3% Rule: The MAV can only increase by 3% each year.
- The Result: Even if your East Medford home skyrockets in value by 20% in one year, your tax bill can only increase by 3% (plus any new voter-approved bonds).
2. Using the “Jackson County Calculator”
Calculating your bill in 2026 requires three specific numbers: the Real Market Value, the Assessed Value, and the Millage Rate for your specific tax code area.
JACKSON COUNTY PROPERTY TAX CALCULATION (2026)
STEP 1: Find your “Assessed Value” Go to the Jackson County Assessor’s website and search for your property address. Ignore the “Real Market Value” or what you paid for the house. You only need the “Total Taxable Assessed Value.”
STEP 2: Choose your Tax Rate (per $1,000 of value)
-
Medford (City): $14.25
-
Ashland (City): $15.10
-
Central Point: $13.90
-
Unincorporated/Rural: $10.00 to $12.00
STEP 3: The Formula (Assessed Value / 1,000) * Tax Rate = Total Annual Tax
EXAMPLE CALCULATION If your Assessed Value is $300,000 and you live in Medford:
1. Divide your value by 1,000: (300,000 / 1,000) = 300
2. Multiply that by the Medford rate: 300 * 14.25 = $4,275
3. Your Total Tax = $4,275 per year.
THE 3% DISCOUNT If you pay the full amount by November 15th, you can take 3% off that total. (Example: $4,275 * 0.97 = $4,146.75)
3. The “New Construction” Trap
This is the most common mistake first-time homebuyers make when moving to Southern Oregon. If you are buying a brand-new home in a development like Eagle Trace or Grandview, the “3% rule” does not apply in the first year.
The Changed Property Ratio (CPR)
When a new home is built, the Assessor hasn’t had 20 years of 3% increments to keep the value low. To make sure new homeowners aren’t paying 3x more than their neighbors, the county uses the Changed Property Ratio.
- The county takes the new home’s Real Market Value (e.g., $550,000).
- They multiply it by the average county-wide ratio of AV-to-RMV (for 2026, this is roughly 0.62).
- $550,000 \times 0.62 = \$341,000$ (Your new Assessed Value).
Buyer Warning: If you see a “Tax Bill” for a new construction listing that says $200, that is the tax for the empty lot. Expect your actual bill to be thousands of dollars higher once the home is finished.
4. 2026 Exemptions: Keeping More of Your Money
Oregon offers several programs to reduce the tax burden for specific groups. In 2026, these limits have been adjusted for inflation.
The Homestead Discount (The 3% Pay-Early Discount)
This is the easiest money you’ll ever make.
- Deadline: November 15th.
- The Deal: If you pay your full tax bill by Nov 15th, the county gives you a 3% discount.
- The Math: On a $4,500 bill, you save **$135** just for paying a few months early.
Disabled Veteran and Surviving Spouse Exemption
Qualified veterans with a service-connected disability of 40% or more can exempt a portion of their home’s assessed value.
- 2026 Exemption Amount: Approximately $28,500–$34,000 off your Assessed Value.
- Impact: This typically results in a $400–$600 annual savings on your tax bill.
Senior & Disabled Citizen Deferral
If you are 62 or older (or disabled) and your household income is below the 2026 threshold (approx. $58,000), the State of Oregon can pay your taxes for you.
- How it works: This is a loan with a low interest rate (approx. 6%). The state pays the county, and the debt is settled when the home is sold or the owner passes away. It is an excellent way for seniors on a fixed income to remain in their homes as Living in Ashland or Medford becomes more expensive.
5. Why Location Matters: Comparing the “Tax Bite”
When choosing between neighborhoods, the tax rate can change your monthly “PITI” (Principal, Interest, Taxes, and Insurance) by $50–$100.
Medford vs. East Medford
Generally, the rates are nearly identical. However, East Medford has several newer “Local Option Levies” for fire protection and police services that can slightly nudge the rate higher than in the downtown core.
The “Ashland Premium”
Living in Ashland, Oregon comes with the highest property tax rates in Jackson County. Between the Ashland School District bonds and the city’s dedicated parks levy, residents often pay $1.00–$2.00 more per $1,000 than their neighbors in Phoenix or Talent.
The “Phoenix/Talent Rebuild” Exception
Following the 2020 Almeda Fire, many homes in Phoenix and Talent were rebuilt. Because they are “new” (Changed Property Ratio), their taxes are often higher than the older homes that survived. However, these towns have some of the most consistent tax rates because they lack some of the larger municipal debt found in Medford.
6. How to Appeal Your Property Tax
If you believe your Real Market Value (RMV) is listed higher than what you could actually sell the house for, you have the right to appeal.
- Timeline: Appeals must be filed between October 25th and December 31st.
- The Process: You petition the Property Value Appeals Board (PVAB).
- Pro Tip: An appeal only saves you money if you can prove the RMV is lower than your AV. Because of Measure 50, your RMV is likely much higher than your AV, meaning an appeal might lower your market value on paper but won’t actually lower your tax bill.
7. Budgeting for 2026: The “Effective Rate”
For a quick “napkin math” calculation while touring Medford homes for sale, use the Effective Tax Rate.
- Medford Effective Rate: ~0.85% of Market Value.
- Ashland Effective Rate: ~1.05% of Market Value.
If a house is listed for $400,000 in Medford, expect an annual tax bill of roughly $3,400 ($400,000 x .0085). This is a safe, conservative number to use when getting pre-approved by your lender.
Summary: Master Your Tax Bill
Property taxes in Jackson County don’t have to be a mystery. By focusing on the Assessed Value, remembering the 3% cap, and planning for the November 15th discount, you can avoid the “escrow shock” that hits many unprepared buyers.
Southern Oregon offers a high quality of life with property tax rates that, while complex, remain significantly lower than the national average and our neighbors in the Midwest or Northeast.

Frequently Asked Questions
Does the property tax reset to the purchase price when I buy a home in Jackson County?
No. This is a common misconception for those moving from states like California. In Oregon, you “inherit” the previous owner’s tax base (the Assessed Value). The sale of the home does not trigger a reassessment to the current market value. Your taxes will continue to grow by the standard 3% per year based on the existing Assessed Value.
When are property taxes due in Jackson County?
Tax statements are mailed out by October 25th each year. You have three payment options:
-
Full Payment: Due November 15th (qualifies for a 3% discount).
-
Two-Thirds Payment: Due November 15th (qualifies for a 2% discount), with the final third due May 15th.
-
One-Third Payment: Due November 15th (no discount), with subsequent payments due February 15th and May 15th.
Why is my neighbor’s tax bill so much lower than mine for a similar house?
This is the “Measure 50 effect.” Because Assessed Values are capped at a 3% annual increase, a home that hasn’t been sold or renovated since 1995 will have a much lower tax base than a home built in 2010. Two identical houses can have vastly different tax bills simply because of when they were built or when major improvements were last made.
I’m buying a new construction home in Medford. Why are the taxes so low on the listing?
Be careful! Real estate listings for new construction often show the “Land Only” tax amount from the previous year. Once the home is completed, the county will apply the Changed Property Ratio (CPR) to the new home’s value.
What is “Tax Compression” and will it lower my bill?
Under Measure 5, there are limits on how much tax can be collected ($10 per $1,000 of market value for general government and $5 for schools). If local tax rates (like new school bonds) push the bill over that limit, the county must “compress” or reduce the taxes.
Are there 2026 tax credits I should know about?
Yes! For the 2026 tax year, some residential owners in Jackson County may see a tax credit on their bills. This is part of a three-year correction (2026–2028) by the County to address previous residential assessment errors. This credit is applied automatically—you do not need to apply for it.
