What Affects Your Take Home Pay in Chicago
Your net pay is determined by a chain of deductions applied to your gross biweekly salary. Here is how each one works:
FERS Pension Contribution
You contribute 0.8% (FERS), 3.1% (FERS-RAE), or 4.4% (FERS-FRAE) of gross pay depending on your hire date. This is deducted pre-tax from federal taxable income but does NOT reduce FICA wages. Authority: 5 U.S.C. §8422.
TSP (Thrift Savings Plan)
Traditional TSP contributions are pre-tax, reducing your federal taxable income. Roth TSP contributions are after-tax and do NOT reduce taxable income. The government matches: 1% automatic + dollar-for-dollar on first 3% + 50¢ per dollar on next 2%. Contribute at least 5% to maximize the match. 2026 limit: $24,500. Authority: 5 U.S.C. §8432(c).
FEHB Health Insurance
Under Premium Conversion (the default), FEHB premiums reduce both federal taxable income AND FICA wages — this is different from FERS and TSP. Your premium depends on the plan you choose. Authority: 5 U.S.C. Chapter 89.
FICA Taxes (Social Security & Medicare)
Social Security: 6.2% on wages up to $184,500. Medicare: 1.45% on all wages, plus an additional 0.9% on wages above $200,000 (single) or $250,000 (MFJ). FICA wages = Gross minus FEHB only. Authority: 26 U.S.C. §3101.
