Real problem, but not really due to inflation. Tax rates are fixed unless your elected officials raise them. The en vogue thing for them to do is artificially inflate land values through 'valuation' which leaves rates the same and increases your taxable value due to a 'paper' increase. You can fix these things by voting, or by challenging the values. This happens in or out of inflationary periods. This is also another area where differences are not just state by state, but county by county as well. Where my land is the AG valuation is pretty low. Land values in the metroplex have outpaced inflation for years. Some people get happy excited when values go up because their property is 'worth more'. They may not understand the costs involved. I would favor systems in which you pay taxes on a rolling average of the value of your property starting the year you took ownership. For example, if you paid 100k for a piece of land, that is the base value of that land. The next year, the assessment comes back at $110k, in my hypothetical system, your base for taxes would be $105k. This would be a hybrid of systems where you only pay on the purchase value and the more common system where you pay based on the mythical assessed value. I think assessments should also have to be no more frequent than 3 years and include an actual site visit or inspection. Most assessment nowadays is just an imaginary number applied based on the sale of new properties in the area with no regard for the actual property itself (or even comparable ones). We have successfully had our property valuation challenged every time. It is just a hassle. They make not hard so you will not challenge it...don't look behind the curtain.
Inflation CAN cause these increases over the long term, but even bad inflation of 10 or 20% would only increase your taxes by 10 or 20%. All of the other increases are thanks to your local officials.
