My employer offers (true but fairly rare) flexible spending accounts.
These allow me to have my gross pay reduced, with the money placed in dedicated accounts for health and dependent care.
The advantage is that this money is invisible for tax purposes; in my case every 5 dollars I elect to have withdrawn is the equivalent of 7 that I don't. With a $3K limit for each account, that's like getting a $2,400 pay raise.
The disadvantages are that 1) the money has to be allocated before the fiscal year, 2) that allocation is not reversible, and 3) you lose any money you don't spend by the end of the year. None of those has been a big deal.
But ... I've found out about a hidden disadvantage. So hidden in fact, that when I tunnelled through multiple layers of help at the IRS to find an expert, the expert had never even thought of the possibility.
Well, here goes: dependent care covers day care but not school. Fair enough - after all this isn't a tuition assistance program. The rub is if your local (public and therefore free) kindergarten is half-day. Clearly, day care in the afternoons is covered. But, what if you would rather pay for a full day of private kindergarten? This isn't covered - even for half the day.
Yep. The government will cut me a break if I don't educate my kid, and will punish me if I do educate them.
Of course, the problem is even stickier than that. Rather obviously, if public schools only offer half-day kindergarten, the niche for private schools is all-day kindergarten. In my small town, all the private kindergartens are all-day. The alternative for working parents is warehousing in daycare for the afternoon.
And ... in the national scheme of things, the money is small potatoes. A half-day at my private kindergarten of choice is $2,250 for the whole year - in many places that won't buy your more than a few months of daycare. Paying for that out of a flexible spending account would save me all of $900.
The flexible spending account offers no flexibility at all for 5 year-olds. A 4 year-old can a get a free ride in daycare or preschool, while a 6 year-old gets no ride whatsoever during regular school hours. But ... the parents of a 5 year-old get screwed.
