I worked it out here[https://news.ycombinator.com/item?id=15625353 https://news.ycombinator.com/item?id=15625353] for the current tax regime. Yale's tuition is actually a bit more than $40k; they quote $47600 for this year. I believe the GOP plan replaces the current standard deduction ($6350) and personal exemption ($4050) with a $12,000 standard deduction, but the first $90k are taxed at 12%, instead of including 10% and 15% brackets. So...12% of ($30,000 stipend + 47,600 tuition - 12,000 deduction) is $7872. Connecticut (where Yale is) also has an income tax that's 3% of the first $10,000; 5% of the next $40,000, and 5.5% of the amount between 50k and 100k. Assuming tuition is also subject to state tax, it works out to 10000 * 0.03 + 400000.05 + 27600 0.055 = $3,818. That works out to a total of $11,690 from take-home pay of $30,000. Ouch.
