How to keep a low property tax base when inheriting a home

Last updated 2026-07-09

What actually happens to property taxes when you inherit a house?

The property tax rarely stays the same after a parent or grandparent dies. Most people expect it to. The transfer of ownership is what breaks that assumption.

In most states, every change of ownership resets the assessed value to current market value. Say your parent bought the house in 1985 for $90,000 and it is worth $800,000 today. The county assessor can reassess it the moment title changes hands. Your annual bill can go from a few hundred dollars to several thousand in one year ^[1].

That reassessment is not a glitch. It is how the system works. Under most state property tax codes, the death of an owner and the transfer to an heir counts as a change of ownership unless a specific statutory exclusion applies. Without an exclusion, the assessor has both the right and the duty to reassess.

Here is the part that saves families money: several states have explicit exclusions that let qualifying heirs step into the deceased owner's tax shoes and keep the inherited base-year value. The rules differ wildly by state. California gets most of the attention because Prop 19 rewrote its rules in 2021, but Florida, Illinois, New York, and others all have partial relief. Even states with no formal parent-child exclusion sometimes cap assessment growth in a way that softens the hit.

Which states let you keep a parent's low assessed value?

No two states do this the same way, and a few have changed their rules recently. Below is an honest summary of the major programs as of mid-2025. Verify with your county assessor or state revenue department before you rely on any of it, because thresholds move through legislation.

State	Program name	What it preserves	Key conditions
California	Prop 19 (eff. Feb 16 2021)	Base-year assessed value	Must be parent's primary residence; heir must occupy within 1 year; $1M value cap applies
Florida	Homestead portability	Save Our Homes capped value	Heir must establish new homestead; different mechanism, similar effect
New York	STAR exemption	School tax relief	Heir must apply for own STAR; does not transfer automatically
Illinois	Senior freeze	Senior's frozen EAV	Heir usually cannot carry it forward; must requalify separately
New Jersey	No parent-child exclusion	N/A	Reassessment at death is standard; some income-based relief
Michigan	Principal residence exemption	Non-homestead millage reduction	Heir must refile within 90 days of occupancy or by June 1 of following year [2]
Texas	Homestead exemption	Flat exemption + 10% cap (not frozen AV)	Heir must refile by April 30; AV is still reset [4]

California's Prop 19 gets the most discussion because it narrowed a previously wide-open exclusion ^[8]. Before Prop 19, California's Prop 58 let any child inherit any property, including rentals, and keep the parent's assessed value with no cap. Prop 19 limited that to a primary residence the heir also uses as a primary residence, and added a value cap. If current market value exceeds the inherited base by more than $1 million, the assessed value gets bumped up by the excess. A property worth $1.5 million with a parent's base of $300,000 lands at $300,000 + ($1,500,000 - $300,000 - $1,000,000) = $500,000, not the full $1.5 million ^[3].

Michigan deserves a flag. Its 90-day deadline for refiling the principal residence exemption is strict and easy to blow in the chaos of settling an estate ^[2]. Miss it and you pay the non-homestead millage rate, which runs about 18 mills higher in many school districts.

How does California's Prop 19 parent-child exclusion actually work?

California earns its own section. The state has the widest gap in the country between what long-held and freshly assessed homes pay, and many families still believe the old Prop 58 rules apply when they do not.

Prop 19 passed in November 2020 and took effect for transfers on or after February 16, 2021. The parent-child exclusion has three requirements ^[3]:

1. The property must have been the parent's principal residence at the time of transfer. 2. The heir must move in and make it their own principal residence within one year of the transfer date. 3. The heir must file the BOE-19-B claim form with the county assessor within three years of the transfer date, or before the property is sold, whichever comes first.

The California State Board of Equalization is blunt that the exclusion is not automatic. Its guidance states the claim "must be filed with the county assessor" and the assessor "will then determine whether the property qualifies" ^[3]. Filing late is common, and it almost always kills the claim.

The $1 million cap trips people up constantly. The cap is not on the value of the home. It is on how far above the parent's assessed value the current market value can climb before a partial reassessment kicks in. If your parent's assessed value was $200,000 and the home is now worth $900,000, the difference is $700,000. That is under $1 million, so the heir keeps the $200,000 base exactly. If the home were worth $1.4 million, the difference is $1.2 million, which is $200,000 over the cap, so the assessed value becomes $200,000 + $200,000 = $400,000, not $1.4 million. Still a big saving.

Prop 19 also created a grandparent-grandchild exclusion, but the conditions are tighter. Both parents of the heir must be deceased at the time of the transfer. Families counting on skipping a generation often find this blocks them cold.

In Los Angeles County, the BOE-19-B goes to the LA County Assessor, a process we cover in our guide to los angeles county property tax. Santa Clara County runs its own assessor portal with online filing for the exclusion form; see our santa clara property tax overview for current contact details.

What is the deadline to file for a property tax exclusion after inheriting?

Deadlines are where heirs lose benefits they legitimately qualify for. Probate, estate administration, and grief eat months, and assessors do not routinely grant extensions. Here are the deadlines for the most common situations.

California: File the BOE-19-B (parent-child) or BOE-19-D (grandparent-grandchild) within three years of the transfer date or before the property is sold ^[3]. The one-year occupancy requirement is separate: the heir must actually move in within one year, or the exclusion is denied no matter when you file the form.

Michigan: Refile the principal residence exemption with the local assessor by June 1 of the year following the transfer, or within 90 days of the date occupancy begins, whichever is later ^[2]. The Michigan Department of Treasury lists both deadlines.

Texas: File a new homestead exemption application with the county appraisal district by April 30 of the year following the year you inherited and occupied the home ^[4]. Texas does not preserve the prior assessed value, but the homestead exemption still cuts the taxable value going forward.

Florida: File a new homestead exemption by March 1 of the year you want it to apply. Portability of the Save Our Homes differential must be claimed on Form DR-501T within three years ^[5].

New York: STAR does not transfer. The heir must apply to the assessor by the annual exemption filing deadline, which varies by municipality but usually falls around March 1 ^[6].

The most dangerous assumption an heir makes is that the exclusion applies automatically. It almost never does. You have to file.

What forms do you need to file, and where do you send them?

The forms depend on your state and sometimes your county. Here is a practical starting list.

California: BOE-19-B (parent to child, or grandparent to grandchild where both parents are deceased). Download it from the California State Board of Equalization at boe.ca.gov ^[10]. Submit it to your county assessor, not to the BOE. Every California county runs its own assessor's office.

Michigan: A property transfer affidavit plus a new Principal Residence Exemption form (Form 2368), filed with the local assessor ^[2]. The Michigan Department of Treasury at michigan.gov/treasury has both.

Texas: Application for Residence Homestead Exemption (Form 50-114), filed with the county appraisal district where the property sits ^[4]. Find your appraisal district through the Texas Comptroller at comptroller.texas.gov.

Florida: Form DR-501 (homestead exemption) and DR-501T (portability claim), filed with the county property appraiser ^[5]. Florida has 67 counties and 67 property appraisers; the Florida Department of Revenue at floridarevenue.com links to each.

One thing nearly every state wants: a copy of the death certificate and evidence of the ownership transfer (the recorded deed, letters of administration, or a certified copy of the will). Some counties also ask for proof of occupancy, like a utility bill or voter registration.

If the estate went through probate, ask the probate attorney to put the property tax exclusion deadline on the closing checklist. Many will not raise it unless you ask.

What if the property was already reassessed before you filed?

This happens all the time. The assessor processes the deed transfer faster than the heir files the exclusion form, and you get a supplemental assessment notice showing a much higher value. Do not panic, and do not assume you missed your shot.

In California, file the BOE-19-B anyway. If you qualify and file within the three-year window, the assessor must rescind the reassessment retroactively ^[3]. That means a refund of any supplemental taxes you paid at the higher rate between the transfer date and the date the exclusion is granted. Ask the assessor's office directly about the refund. It is not always started for you.

In Michigan, if you missed the principal residence exemption deadline, you can file a late claim but you usually lose the exemption for the year or years you missed. The Michigan Tax Tribunal hears appeals if the assessor denies a late claim.

In Texas, late homestead exemption applications are allowed for up to two years after the deadline under Texas Tax Code Section 11.431 ^[9]. You pay the taxes as assessed in the meantime, and a granted retroactive exemption produces a refund.

The lesson is simple: even if you think the window closed, call the assessor and ask. Many will tell you straight whether a late filing has a real chance. And if the assessor denies your exclusion claim and you think you qualify, you have the right to appeal that denial, which is a separate process from appealing the assessed value itself.

Does inheriting a home through a trust avoid the reassessment problem?

Trusts show up in estate planning mostly to avoid probate, and their property tax treatment is genuinely fiddly.

In California, a transfer to a revocable trust where the parent stays trustee during life is generally not a change of ownership for property tax purposes ^[3]. When the parent dies and the property passes to a child as successor trustee or beneficiary, California treats it as a parent-to-child transfer, and the Prop 19 exclusion can still apply. The heir still has to file the BOE-19-B and meet the occupancy requirement.

Irrevocable trusts are harder. If the parent gave up control to an irrevocable trust years before death, the transfer into the trust may have already been a change of ownership at that point, triggering reassessment then instead of at death. The California BOE publishes change-in-ownership guides at boe.ca.gov that sort out which trust transfers count ^[3].

Other states vary. Michigan treats a transfer to a revocable trust as not a change of ownership as long as the settlor stays a beneficiary during life ^[2]. Florida uses similar logic.

The general rule across states: a revocable living trust neither helps nor hurts you on reassessment. What matters is the transfer to heirs at death, and the exclusion rules apply to that moment the same as they would without a trust. An irrevocable trust is a different animal and deserves a conversation with a property tax attorney or the county assessor before you move the deed.

Can you appeal the reassessment if no exclusion applies?

Yes. Even if no statutory exclusion saves the inherited base, you can still contest whether the new assessed value matches actual market value.

Assessors doing a change-of-ownership reassessment use mass-appraisal methods. They pull recent comparable sales and run a formula against your property. That formula can spit out a value higher than what the house would actually fetch, especially if the home has deferred maintenance, a bad floor plan, or other problems the mass appraisal never sees.

Inherited a home that needs $80,000 in roof and HVAC work? The assessed value should reflect that. Get a licensed appraiser or pull your own comparable sales to support a lower number. Then file an appeal with your local assessment appeals board before the annual deadline, which in most states runs 30 to 90 days after the assessment notice is mailed.

The appeal process for an inherited home is the same as any other property tax appeal. You argue that the assessor's estimated market value is too high next to what similar homes actually sold for near the assessment date. For a step-by-step on building that case yourself, TaxFightBack's DIY appeal kit walks you through pulling comps, calculating adjustments, and presenting evidence, so you keep 100 percent of any reduction instead of handing a cut to a contingency firm.

What if the home is used as a rental after you inherit it?

This is where Prop 19 changed California hard. Under the old Prop 58 rules, an heir could inherit any property, including rentals and investment homes, and keep the parent's assessed value. Prop 19 shut that down. Inherit a home and do not make it your primary residence, and there is no exclusion. The property gets reassessed at full current market value, full stop ^[3].

Other states run a bit softer but not much. In Texas, a rental cannot get the homestead exemption, so inheriting versus buying makes no difference from an exemption standpoint. Michigan's principal residence exemption also requires owner-occupancy.

If you are inheriting a home mainly as an investment and plan to rent it, the honest answer is that most states will reassess you and you will pay taxes on current market value. The strategy then shifts to two things: (1) making sure the assessed value is accurate rather than inflated, which you can contest on appeal, and (2) remembering that property taxes on rental income are a deductible expense for federal income tax purposes under IRC Section 162.

Some heirs try to thread the needle: occupy the property briefly, file for the California exclusion, then convert it to a rental. California treats a later switch to non-primary use as a new change of ownership for the exclusion. The base-year value locks in when you qualify, but there are limits on how long you can be absent before the principal residence status gets questioned.

What about inheriting a home in a state with no special exclusion?

About half of U.S. states have no meaningful parent-child exclusion for property tax. In those states, the transfer at death is a change of ownership and the assessor reassesses to current market value, no exceptions.

If you are in one of those states, your options narrow to three:

1. Challenge the assessed value through the normal appeal process described above. 2. Apply for any income-based or age-based exemptions you personally qualify for, like senior exemptions, veteran exemptions, or circuit-breaker credits. These attach to you as the new owner, even if they never applied to your parent. 3. If the estate is complex enough, ask a property tax attorney whether any timing or entity structuring could produce a better result. This is rarely worth the cost for a single-family home but can matter for inherited commercial or multi-family property.

New York deserves a note. New York has STAR (School Tax Relief), which lowers the tax on primary residences, but STAR does not freeze or cap assessed value growth the way California's Prop 13 does ^[6]. Inheriting in New York means accepting the current market-value assessment, then applying for STAR and any other exemptions you qualify for. The nyc property tax system is tangled enough to deserve its own review if you are inheriting in the five boroughs.

What are the most common mistakes heirs make with property taxes?

A short, blunt list of what actually goes wrong.

Missing the filing deadline. This is the number one way heirs lose a benefit they qualify for. The deadline is real. Probate attorneys tend to focus on income and estate taxes and skip the property tax exclusion deadline.

Assuming the exclusion applies automatically. It does not, anywhere. You must file a form.

Not occupying the home within the required window. In California, the one-year occupancy requirement is separate from the three-year form-filing window. You can file on time and still lose the exclusion if you never moved in within a year.

Accepting an inflated reassessment without appealing. Assessors are not always right. A change-of-ownership reassessment is an estimate. If comparable sales say your home is worth less than the assessor claims, appeal.

Forgetting to refile for other exemptions. Even without a base-value exclusion, the prior owner may have had a homestead, senior, or veteran exemption that died with them. Refile for any exemption you qualify for in your own right.

Confusing estate tax with property tax. The federal estate tax exemption ($13.61 million per individual for 2024, per IRS Publication 559) has nothing to do with property tax ^[7]. Two separate systems. Plenty of heirs burn energy worrying about estate tax when the real hit to their monthly finances is the property tax jump.

Frequently asked questions

Does inheriting a house automatically trigger a property tax increase?

In most states, yes. The transfer of ownership at death counts as a change of ownership, which lets the assessor reassess the property to current market value. Whether the reassessment happens and how large it is depends on your state's rules and any exclusion. States like California have partial exclusions for heirs who move in as a primary residence. Most states have none.

How do I apply for California's Prop 19 parent-child exclusion?

Download the BOE-19-B form from the California State Board of Equalization at boe.ca.gov and submit it to your county assessor, not to the BOE. You have three years from the transfer date, or until the property is sold, whichever comes first. You must also move in as your primary residence within one year of the transfer, or the exclusion is denied even if the paperwork is on time.

What is the deadline to file for a property tax exclusion after inheriting in California?

Three years from the transfer date, or before the property is sold, whichever comes first. The BOE-19-B goes to your county assessor. Separately, you must occupy the home as your primary residence within one year of inheriting it. Miss either deadline and you generally get no exclusion and no recovery of the base-year value.

Can I keep my parents' low property tax if I rent out the inherited house?

Not in California under Prop 19. If you do not make the inherited home your primary residence, no exclusion applies and the property gets reassessed at full current market value. Most other states have no exclusion at all regardless of occupancy. If you plan to use the home as a rental, assume a reassessment and budget for it.

Does a living trust protect property from reassessment when the owner dies?

Generally no, but it does not make things worse either. A transfer from a revocable living trust to an heir at the trustor's death is treated the same as a direct inheritance in most states. In California, the Prop 19 exclusion still applies to the trust transfer, as long as the heir meets the occupancy and filing rules. An irrevocable trust raises harder questions and may have triggered a change of ownership when the property first went in.

What happens if the assessor already reassessed the property before I filed for an exclusion?

In California, file the BOE-19-B anyway. If you qualify, the assessor must rescind the reassessment retroactively and you can get a refund of supplemental taxes paid at the higher rate. In Texas, a late homestead application is allowed for up to two years after the original deadline under Tax Code Section 11.431. Always ask the assessor's office whether a retroactive correction is possible before assuming the money is gone.

Is there a property tax exclusion when inheriting a home in Texas?

Texas has no parent-child assessed-value exclusion. Every transfer of ownership resets the assessed value to market value. What you can do is apply for a new homestead exemption in your own name, which cuts the taxable value by a flat amount and caps annual assessment increases at 10 percent. File Form 50-114 with your county appraisal district by April 30 of the year after you inherit and occupy the home.

Can I appeal the new assessed value after inheriting a home?

Yes. Even without an exclusion, you can contest whether the assessor's estimated market value is accurate. If comparable homes sold for less than the assessor's figure, you have a real appeal. Gather recent sales of similar properties within roughly a half-mile, document any deferred maintenance or condition issues, and file your protest before the annual deadline, which is usually 30 to 90 days after the assessment notice is mailed.

What exemptions should I refile for after inheriting a home?

Any exemption tied to your parent's personal status, like a senior citizen exemption, veteran exemption, or disability exemption, ends when the prior owner dies. You have to apply separately for any exemption you qualify for in your own right. In most states that means filing a new homestead exemption application at minimum, plus senior or veteran exemption forms if you are eligible.

Does the $1 million cap under California Prop 19 mean I automatically keep the old base if the home is under $1 million?

The cap is on the difference between the home's current market value and the parent's assessed value, not on the total market value. If the parent's assessed value was $200,000 and the home is worth $900,000, the difference is $700,000, below the $1 million threshold, so the heir keeps the $200,000 base. A home worth $1.5 million with the same $200,000 base has a $1.3 million difference, so $300,000 gets added back to the base.

How long does it take for the assessor to process an exclusion claim?

Processing times vary widely by county. In California, large urban counties like Los Angeles and Santa Clara can take six to eighteen months to process a BOE-19-B claim. File right after the transfer and keep copies of everything. If the assessor issues a supplemental tax bill before the exclusion clears, pay it to avoid penalties, then request the refund once the exclusion is granted. Do not wait for approval before paying the interim bill.

What documents do I need to file for a property tax exclusion when inheriting?

Most states want the completed exclusion or exemption form, a certified copy of the death certificate, proof of the ownership transfer (a recorded deed or letters of administration), and proof of your occupancy if the exclusion requires it, such as a utility bill or voter registration. Some counties also ask for a copy of the trust document if the property passed through a trust. Call the assessor's office before mailing anything to confirm their current checklist.

Does inheriting a home in Florida give me any property tax protection?

Florida has no parent-child exclusion like California's Prop 19. The home gets reassessed at market value when you inherit it. What Florida offers is a homestead exemption (file Form DR-501 by March 1) and a separate portability benefit for your own prior homestead, if any. The prior owner's Save Our Homes capped value does not transfer to you; it ends with their homestead.
