Yes the current chatter is that they are going to consider both incomes even for people who filed separately. So you miss out on the joint filing benefits AND still have higher payments.
I assume there will be lawsuits over this if it moves forward, because allowing married borrowers to file separately and therefore have income based repayment calculated only on their individual income is written into the law.
It may not even move forward because of that, sometimes this administration talks about doing things before talking to their lawyers. But it's definitely going to cause some anxiety in the meantime.
The Trump administration said married couples filing separate tax returns would have their spousal incomes used for monthly student-loan payments.
