⚠️ Critical for Student Loan Borrowers:
This AGI calculation includes the complex Social Security provisional income rules that most calculators ignore. Your final AGI determines eligibility and payment amounts for IBR, PAYE, REPAYE/SAVE, and ICR plans. Maximizing above-the-line deductions while understanding Social Security taxation can significantly reduce your monthly payments.
📚 Legal References & Key Information
IRC § 62: Definition of adjusted gross income and complete list of above-the-line deductions
IRC § 86: Taxation of Social Security benefits based on provisional income thresholds
34 CFR 682.215 & 685.209: Use of AGI for income-driven student loan payment calculations
Provisional Income Formula: AGI (before SS) + ½ Social Security + Tax-exempt interest
SS Thresholds: Single/MFS: $25,000 & $34,000 | MFJ: $32,000 & $44,000
Student Loan Impact: AGI determines discretionary income which directly affects payment amounts. Married filing separately excludes spousal income but may include more Social Security income in AGI.
