I bond and Treasury interest

Federally taxable

Is I bond interest Taxable?

Short answer: Yes federally, but exempt from state income tax; I bond interest can be deferred until you cash out.

I bond interest can be tax-free if used for higher education under income limits.

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.
