The Canada Child Benefit presents a new wrinkle in my tax optimization efforts (this isn't new news, except that the program is a go; details were available during the election campaign.) The way it seems to be structured, for family income over $65,000 there's a reduction in CCB received equivalent to 5.5% of that additional income (based on two kids under six.)
I'm in the midst of some lower income years and have been de-registering some RSP investments to take advantage of the lower tax bracket. If I was refunded 31.15% tax on that RSP contribution and now only pay 20.05% when de-registering, great! Saved 11.1%!* But if the CCB reduction in benefits really means I've saved only 5.6%, well, that's not nearly as attractive, mathematically**. I could make a good argument for waiting to de-register, once CCB isn't a factor (though gambling on future tax rates not being dramatically higher.)
Something for me to think about for 2016 tax year.
* And possibly more, depending on Ontario Health Premium.
** Other questions do come into it. Do I feel right trying to optimize receipt of benefits primarily intended to assist impoverished children? Are we really wealthy enough to reasonably forego some of this benefit by not optimizing?
