Thinking about moving in Marin but worried you will lose your low property tax bill? You are not alone. Many Sausalito and San Rafael homeowners want a better fit without a big jump in annual taxes. The good news is that California’s Prop 19 can let you transfer your taxable value to a new primary home if you qualify. In this guide, you will learn who is eligible, how the math works, what to file, and the practical steps for a smooth transfer in Marin. Let’s dive in.
Prop 19 basics in Marin
Prop 19, in effect since February 16, 2021, expanded the ability for certain homeowners to transfer the taxable value from their primary residence to a new primary home anywhere in California. This can lower your property tax bill compared to what you would pay without a transfer.
You may be eligible if you are one of the following:
- A homeowner age 55 or older.
- A severely disabled homeowner.
- A homeowner whose primary residence was substantially damaged or destroyed by wildfire or another natural disaster.
Key points to know:
- The transfer applies only to a primary residence, not to second homes or investment property.
- Portability is now statewide, so you can move within Marin or to another county.
- The law limits how many times you can transfer if you are age 55 or disabled. Many references note up to three transfers, but you should verify the current limit with the Marin County Assessor.
How the tax transfer math works
Under Prop 19, you can move your original home’s taxable value to your replacement primary residence. Your new taxable value depends on how the replacement home’s market value compares to the original home’s market value at the time of sale.
Equal or lesser value replacement
If your replacement home’s market value is equal to or less than your original home’s market value, your original taxable value generally carries over without an increase. Your annual bill is then based on that transferred value, plus normal Prop 13 inflation adjustments and local assessments.
Higher value replacement
If your replacement home’s market value is higher, the assessor typically adds the difference to your transferred taxable value. In plain language: new taxable value equals your transferred taxable value plus the amount that the replacement home’s market value exceeds the original home’s market value.
Marin examples to illustrate
These are simple hypotheticals for clarity. Actual values come from the assessor and your closing documents.
Downsizer example in Sausalito to San Rafael: Your original home has a market value of $1,200,000 and a taxable value of $300,000. You buy a replacement home for $900,000. Because $900,000 is less than $1,200,000, you can transfer the $300,000 taxable value to your new home.
Move-up example in Southern Marin: Your original home’s market value is $800,000 and its taxable value is $250,000. You buy a replacement home for $1,500,000. The difference in market values is $700,000. Your new taxable value would be $250,000 plus $700,000, which equals $950,000.
Supplemental bills and local charges
Expect supplemental assessments as the assessor processes your purchase and the transfer. The 1 percent base tax rate still applies to the new taxable value. Marin also has voter-approved parcel taxes and special district charges that continue to apply and are not reduced by a Prop 19 transfer.
Eligibility and timing steps
To qualify, you must show that the original and replacement properties are your primary residences and that you meet age, disability, or disaster criteria. You will also need to file a claim with the county where the replacement home is located.
What the assessor may request:
- Proof of primary residence for the original property, such as a driver’s license address, voter registration, or utility bills.
- Proof of eligibility. For age, provide a driver’s license, passport, or birth certificate. For disability, provide a physician’s certification or qualifying program documents. For disaster, provide insurance or government records showing substantial damage.
- Closing documents for both transactions. Include recorded grant deeds and final escrow settlement statements.
- Any prior base value transfer approvals or claim numbers.
Timing window to confirm locally:
- Replacement purchases generally must occur within a set period before or after the sale of the original property. Many summaries reference a two-year window, but you should verify the exact timing and filing deadlines with the Marin County Assessor. File your claim promptly to avoid delays.
Marin process tips that smooth escrow
Coordinating early with the assessor and your escrow team makes a big difference. Here is how to keep things on track in Marin.
- Contact the Marin County Assessor-Recorder early in escrow to review eligibility, forms, and what evidence they prefer.
- Ask if the assessor can provide a written confirmation or claim number you can share with your title and escrow team.
- Request guidance on how supplemental billing will be handled so prorations at closing are accurate.
- Moving within Marin, such as Sausalito to San Rafael, may simplify logistics since one county is involved, but you should still confirm procedures and deadlines in advance.
Local factors in Sausalito and Southern Marin
Marin’s high home values influence how helpful a transfer will be.
- Downsizing can be powerful. If your replacement home costs the same or less than your original, you may keep your low taxable value.
- Move-up purchases still help. You might see an upward adjustment when the replacement is more expensive, but it can still be far lower than taxing the full market value.
Other local considerations:
- Parcel taxes and special districts. The 1 percent base rate applies to the adjusted taxable value, but local assessments for things like sewer, lighting, open space, and school-related parcel taxes still add to the bill. Review the replacement property’s tax profile.
- Inheritance planning. Prop 19 narrowed parent-to-child and grandparent-to-grandchild exclusions. In many cases, a child must use the home as a primary residence and a valuation cap applies. This is a complex area, so talk with an estate planning attorney or tax advisor before making decisions.
Common pitfalls to avoid
- Waiting too long to file your claim or missing county-specific forms.
- Assuming second homes or investment properties qualify. Prop 19 applies only to primary residences.
- Overlooking parcel taxes and special assessments that still apply to the replacement property.
- Confusing property tax portability with capital gains rules. Prop 19 affects property tax assessed value only.
Practical next steps
Use this simple checklist to move forward with confidence:
- Call the Marin County Assessor-Recorder to confirm eligibility, timing, and the correct claim form.
- Gather documents: proof of primary residence, age or disability or disaster records, recorded deeds, and escrow statements.
- Share the assessor’s guidance with your escrow officer so prorations and supplemental bills are handled correctly.
- After closing, confirm the transferred taxable value appears on your replacement property record and review your next tax bills for accuracy.
