I recently married (June 2014).  We’re an older couple.  I have no student loan debt, but my wife has about $78,000 in student loan debt and has been enrolled in Income Based Repayment for a couple years. We plan to file taxes this year married but filing separately based on the existing rule where her IBR is based solely on her income. If the proposed budget changes get passed, will our combined income be used to calculate her IBR, or will my income be excluded in calculating her IBR?  She makes about $16,000/year as a teacher, and pays something like $150/month right now.  But If my income is included, it would go up to something like $1200/month!

Wondering the same thing. I guess a divorce is in our future?

Short answer, no! Long answer below

I plan to begin IBR and file married filing separately in a few years.  Do you know if I would be able to apply under the old rules or would I have to apply under the new rules?
