TSP contributions
Up to $24,500
Can You Write Off TSP Contributions?
Short answer: Traditional TSP contributions are already excluded from your W-2 wages; Roth TSP isn't deductible.
Catch-up adds $8,000 at 50+, or $11,250 at ages 60–63.
Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
