Most taxpayers know that interest from U.S. Treasury securities is taxable on the federal return. What many do not realize is that this income is generally exempt from state and local income tax.

The exemption can apply to:

• Interest received directly from Treasury bills, notes, and bonds.

• The portion of a mutual fund or money market fund dividend attributable to qualifying U.S. government obligations.

That second category is where the deduction most often gets missed.

So if you’ve ever wondered, “Why does my tax professional charge so much?” or “Why did my fee go up this year?” this post is for you.

The short answer is this: complexity takes time, and during tax season, time is the scarcest resource in the building.

The good news? There are practical ways to make your return easier, cleaner, and sometimes less expensive to prepare.

When you’re a physician, consultant, or small business owner with income that crosses state lines, the rules start to feel like an interstate turf war.

Each state wants its cut — and unfortunately, they’re not always good at sharing.
