I just checked my HOA for a neighborhood of more or less cookie-cutter homes. There’s a line in the annual operating budget for property taxes, and every budget line shows both the actual amount expended last year and the amount budgeted for this year. Any zeros on this line should have tipped somebody off. It would be interesting to see if they budgeted for taxes and then simply didn’t pay them.
If the budget didn’t catch the error, it seems like an audit should have. The annual operating budget determines the frequency, but even at the bare minimum (annual budget less than $75,000) an audit by an independent CPA is required every four years. I’m no CPA, but shouldn’t that have come up here?
