In California, the meaningful property tax break arrives at a 100% rating; at 90%, the state's exemption generally does not apply. The Disabled Veterans' Exemption is tied to a permanent-and-total disability rating, or to being compensated at the 100% level due to individual unemployability. It reduces your home's assessed value before taxes are calculated, which at typical California tax rates works out to roughly a couple thousand dollars of savings a year. The state sets the exact exemption amount and adjusts it over time, and there is an enhanced version for lower-income veterans, so confirm the current figures with your county assessor. At a 90% rating, the exemption is generally unavailable, because California uses that 100% permanent-and-total threshold rather than a sliding scale. It is worth checking whether other benefits you qualify for stack, but the assessed-value exemption itself is the 100% benefit. This also varies enormously by state. Texas, for example, goes further and fully exempts a 100% permanent-and-total disabled veteran from property taxes altogether. If you are comparing locations or estimating your carrying cost, look up your specific state and county rules rather than assuming California's treatment applies everywhere. These programs change, so verify current eligibility and amounts before you count on them.
