What taxes has the least elastic?

Taxes that are considered least elastic typically include those on necessities, such as sales tax on basic goods like food and medicine. Since consumers need these items regardless of price changes, demand remains relatively stable even when taxes increase. Additionally, property taxes can also be inelastic, as homeowners are less likely to change their housing decisions in response to tax fluctuations. Overall, the demand for these taxed goods remains consistent despite changes in tax rates.
