The RAP Marriage Penalty: Jointly vs Separately
RAP bases your payment on the AGI from your tax return. File jointly and it counts both incomes; file separately and it counts only yours. For two earners, that difference is the marriage penalty.
A worked example
Two spouses each earning $50,000, no dependents:
| Filing status | AGI used | RAP payment |
|---|---|---|
| Married filing separately | $50,000 (your income) | $167/mo |
| Married filing jointly | $100,000 (combined) | $750/mo |
Filing jointly costs about $583/month more here — roughly $7,000 per year — because the combined income lands in a higher RAP bracket.
Estimate your own payment
Enter your individual AGI (filing separately) or your combined AGI (filing jointly):
The trade-off
Filing separately can shrink your RAP payment, but it often raises your taxes and disqualifies you from credits like the student loan interest deduction. Weigh the monthly RAP savings against the extra tax — for many couples the student-loan savings only win when both spouses earn similar amounts and carry large balances.
Frequently asked questions
Does RAP have a marriage penalty?
Yes. If you file taxes jointly, RAP bases your payment on your combined household AGI, which usually pushes you into a higher bracket. Filing separately lets RAP look only at your own income, which can lower the payment — but you may lose other tax benefits.
Should I file separately to lower my RAP payment?
It can help if both spouses earn similar incomes, because each payment is then based on a single income in a lower bracket. But married-filing-separately can raise your tax bill and reduce credits. Compare the student-loan savings against the extra tax before deciding, ideally with a tax professional.
Does my spouse’s income count under RAP?
If you file jointly, yes — RAP uses your joint AGI. If you file separately, RAP uses only your individual AGI. This is the core lever behind the RAP marriage penalty.
