Treasury Bonds vs Corporate Bonds

Compare US Treasury bonds and corporate bonds — credit risk, yield, and tax treatment.

Overview

Treasuries are issued by the US government and considered the safest fixed-income asset. Corporate bonds carry credit risk and pay a higher yield to compensate. Treasuries are also exempt from state income tax — a meaningful edge in high-tax states.

Choose Treasury Bonds when...

Choose Treasuries (or Treasury-only funds) for the safest portion of your portfolio, or in a taxable account in a high-tax state.

Choose Corporate Bonds when...

Add corporate bonds (usually via a total-bond-market or investment-grade fund) for higher yield and broader diversification within fixed income.

Our Verdict

For the safe portion of your portfolio, Treasuries are unmatched — zero credit risk and state tax exempt. For broader fixed-income exposure, a total-bond-market fund mixes Treasuries, agency MBS, and investment-grade corporates. Avoid concentrating in junk bonds unless you understand the equity-like risk.
