The Virginia Constitution requires that Real Estate be assessed at 100% of market value in all jurisdictions. This is done as of Jan 1st each year. Most folks with a mortgage pay their taxes in equal monthly escrow payments with their mortgage. Those not paying that way get a bill from their local jurisdiction payable in two payments, the first usually in June or July and the second in December. I don't know of a prohibition that would preclude monthly payments to each jurisdiction, although you may have to do it on your own. You might want to suggest monthly or quarterly payment plans at the next meeting of your local governing body.
