My SO and I are dealing with double taxes for our second year since we moved to Montreal (he is dual, I will become dual soon). I'm wondering if anyone has figured out strategies to leverage retirement funds, specifically RRSPs and IRAs, in both countries to lower taxes as much as possible. In general, Canadian taxes should be higher and offset the US taxes. However, we are both regarded as self-employed here (grantees, actually) and not in the US (just me, lower salary) so cannot write off all our expenses for the US taxes.
My idea is to have my SO max out his RRSP contributions to lower Canadian taxes, and I will continue to put money into my IRA to lower US taxes. I should add that we made around $55K USD in 2015. That is likely to increase going forward, which is why I'm trying to figure this out now.
Does this idea make sense? Open to any and all strategies and ideas. I would love to know what anyone else in this awkward, annoying position is doing to make this work. Thanks!
