We pay quarterly. Actually got a little back from last year. It was applied to the first quarter and had to cut another check to cover the balance.
I keep looking for the 48% to step up and do "their share". Personally, I don't think taking entitlements constitutes "their share".
While you are looking for the deadbeats to pay their share when they can't even pay attention, I'm looking for the wealthy to pay their share, when they have the money and will get by just fine.
Now who has the most realistic chance of getting someone to pay their share?
