Prior to this year (2019) maintenance (formerly called alimony) was tax deductible by the person paying the maintenance. It was taxable income for the person receiving it. This all changed on January 1, 2019.
Now, maintenance will no longer be tax deductible for the one paying it. And maintenance received will not longer be taxable income for the one receiving it.
This puts pressure on the higher income spouse to pay less maintenance because there is no longer a deduction. I doubt it will have much impact on the lower income spouse's efforts to obtain maintenance, especially in Colorado where the state has established presumptive guidelines for maintenance.
The takeaway from all this is to scrutinize divorce settlement proposals from every angle, including the tax angle. Check with your tax specialist to see your whole financial picture when negotiating the numbers in a divorce. You might find that seeing the actual tax burden will impact your decision making.
