Thinking about selling your Glendale home and buying bigger, but worried about a jump in property taxes? You are not alone. Many longtime homeowners hesitate to move because their current taxable value is far below today’s market. If you qualify, California’s Proposition 19 may let you carry some or all of your lower taxable value to a new primary residence anywhere in the state. In this guide, you will learn what Prop 19 changed, who qualifies, how a move-up transfer works, and the steps to take in Glendale to keep your timeline on track. Let’s dive in.
Prop 19, approved in November 2020 and effective April 1, 2021, expanded the ability for certain homeowners to transfer their base-year assessed value to a replacement primary residence. This rule is often called “portability.” It is designed to help eligible owners move without losing the benefit of a lower taxable value.
Under Prop 19, you can transfer your base-year value to a replacement home located anywhere in California. The replacement must become your principal residence. If you buy a more expensive home, you can still receive partial relief, but your assessed value will be adjusted upward to reflect the higher market value.
Prop 19 also changed parent-to-child and grandparent-to-grandchild transfer rules. Those changes are separate from portability. If you recently inherited property or plan to, review those rules separately before you sell or convert a property to a rental.
To use portability, you must be in one of these categories:
You must have owned and occupied the original property as your principal residence. The replacement home must also become your principal residence. Counties typically require objective proof of residency for each property.
Here are the key parameters Glendale homeowners should know:
The county assessor determines your new assessed value using Prop 19 rules.
Most eligible owners can use portability a limited number of times in their lifetime. Many county explanations cite up to three transfers for age 55+ or severely disabled owners. Because rules and procedures can evolve, confirm your available transfer count with the Los Angeles County Assessor.
Prop 19 does not change federal income tax rules. The federal capital gains exclusion for a principal residence, generally $250,000 for single filers and $500,000 for married couples filing jointly, still applies separately.
Moving up often involves two transactions that must fit within the Prop 19 timeline. A little planning can save time and stress.
Verify whether you qualify based on age, disability, or disaster-related loss. Ask the Los Angeles County Assessor which documents prove eligibility, such as proof of birthdate or acceptable disability documentation.
Sketch a timeline for your sale and purchase that fits within the two-year window. If you can, coordinate your sale and purchase close together. This makes it easier to document principal residence status and file your claim promptly.
Gather your current assessed value and an estimate of your home’s market value. Ask the assessor for an illustrative calculation showing how your base-year value could transfer at your expected purchase price. This helps you compare property tax outcomes with and without portability as you set your budget.
Work with your agent to structure contingencies, rent-backs, or a short interim rental if needed. The goal is to close within your planned window and ensure you can move into the replacement home as your principal residence.
Make sure escrow and title teams understand your intent to file a Prop 19 claim. Ask them to prioritize complete, clearly labeled closing packages, since the assessor will rely on these documents.
Before you close on your replacement home, gather these items so you can file promptly:
Ask the Los Angeles County Assessor when and how to submit the portability claim form. Filing practices can vary, and there may be specific deadlines to meet after your sale or purchase.
Once your claim is submitted, the assessor reviews your documentation and applies the rules. If your claim is approved, you will receive a revised assessment notice. Your next property tax bill will reflect the adjusted assessed value. Keep copies of all filings, determinations, and closing documents for your records.
A few missteps can cause delays or higher-than-expected taxes. Stay ahead of these items:
