I don't think you understand my point or how taxation works as a closed system. If all these families with one spouse earning more get a new tax break (up to $30k as you say) there will be $XBillion less in revenues. A responsible government will need to raise somebody else's taxes to make up that money. Unlike cutting top marginal rates or corporate taxes this change would also not have any economic benefit. In fact it is likely to discourage some spouses from working so would further decrease revenues and the labour force.taxrage wrote: ↑Nov 4th, 2017 5:17 pmA joint return could be made optional. In the US, couples can file as individuals or as couples. Canada could do the same.
Currently, families with one spouse earning most/all of the income pay a lot more tax - as much as $30K more. This problem is why this entire thread exists. Business owners have used family members who have no involvement in the business to reduce their personal tax liability. They'll continue to try and exploit this "loophole" forever. Eventually, government will see the light.
I think if we are going to cut income taxes we should be incentivizing work not dis-incentivizing it.
