Posted May 18, 2024 ![money-house-seesaw-IS-1048402108](https://www.realized1031.com/hs-fs/hubfs/Images/photo/abstract/money-house-seesaw-IS-1048402108.jpg?width=750&height=392&name=money-house-seesaw-IS-1048402108.jpg) Whether you own your own home (and use it as a primary residence) or own investment properties, you understand one thing. Namely, state and local property taxes[ can generally be deducted from your federal income taxes.](https://www.investopedia.com/terms/p/property_tax_deduction.asp) While the Tax Cuts and Jobs Act of 2017 caps those deductions at $10,000 (or $5,000 if you are married and filing separately), the deductions can be used to help offset your income. The result is a potentially lower tax burden. But what happens if you live in a state that assesses supplemental property taxes? Can that be considered a legitimate deduction? In a word, yes. Now, let’s continue on this topic and learn what supplemental property tax is. ### Defining a Different Tax One challenge involved with finding information about supplemental property taxes is that they are assessed mainly on a state level. More specifically, only California mentions anything about supplemental property taxes.  ### But what are they? [Supplemental taxes](https://dtac.sccgov.org/frequently-asked-questions-faqs/property-taxes-frequently-asked-questions-faqs#:~:text=%22Supplemental%22taxes%20are%20additional%20secured,(see%20Secured%20Tax%20definition).) are additional, secured taxes due when a property changes owners, or is renovated. Another thing to know about this type of tax is that it’s sent out in addition to the regular, secured annual tax on a property.  In California,[ this tax dates back to July 1983](https://www.co.monterey.ca.us/government/departments-a-h/assessor/assessor/real-property/supplemental-assessments), when Senate Bill 813 amended the California Revenue & Taxation Code, leading to the creation of “supplemental assessments.” These reassessments reflect an increase or decrease in property tax generated by a supplemental event, such as a sale or renovation. It becomes effective on the first day of the month following a change in ownership or new construction completion date.  To determine that supplemental tax, an assessor examines a property’s fair market value, then subtracts its prior assessed value. The difference between the two is dubbed the “net supplemental value,” which is enrolled as a supplemental assessment. If that net supplemental value is negative, your property’s value has declined, meaning a supplemental tax refund check will end up in your mailbox. If that supplemental value is positive, a supplemental tax bill is generated. You need to pay this bill in addition to your annual property tax bill. Adding to the confusion, you could receive two supplemental tax bills, depending on the date of your reassessment. If the supplemental event takes place on or between January 1 and May 31, you’ll receive two bills: - The first bill is for the current fiscal year when the supplemental event took place - The second bill is for the upcoming fiscal year ### Taking the Deduction While supplemental tax bills might seem like more paperwork, they are eligible for federal deductions.[ According to Intuit](https://ttlc.intuit.com/community/business-taxes/discussion/are-my-supplemental-tax-payments-deductible-if-so-where-do-i-enter-the-amounts/00/775939), you can enter those taxes with the original taxes paid on your home (by selecting “deductions and credits” and inputting the information under “real estate taxes”).  The final takeaway on this topic is that supplemental taxes are a state-level thing. California has them. So does Texas – though[ supplemental taxes in the Lone Star State](https://texas.public.law/statutes/tex._tax_code_section_42.42) are more of a corrective nature, generally in the face of an appeal. The state-level supplemental tax issues and questions are best answered by tax professionals familiar with the state’s tax codes.   This material is for general information and educational purposes only.

Investing in alternative assets involves higher risks than traditional investments and is suitable only for sophisticated investors. Alternative investments are often sold by prospectus that discloses all risks, fees, and expenses. They are not tax efficient and an investor should consult with his/her tax advisor prior to investing. Alternative investments have higher fees than traditional investments and they may also be highly leveraged and engage in speculative investment techniques, which can magnify the potential for investment loss or gain and should not be deemed a complete investment program. The value of the investment may fall as well as rise and investors may get back less than they invested. This site is published for residents of the United States who are accredited investors only.
