re: Can someone explain millages?

Each tax "mill" equals one-tenth of a cent.

So if the taxable assessed amount on a piece of real estate is $50,000 and the millage tax rate is 10 mills, that would mean, in effect, the assessed rate is one cent times $50,000, or $500.

ETA: In Louisiana it's a little more complicated in that real estate is assessed at 10% of its "fair market value."

So if a property has a fair market value of the above mentioned $50,000, the assessed amount is $5,000. So 10 mills would be applied to $5,000 resulting in a property tax liability of $500.
