SIE Municipal Fund Securities

Municipal fund securities are 529 plans, ABLE accounts and local government investment pools. The wrinkle the SIE tests is that although a 529 invests in mutual funds, it is regulated as a municipal security under MSRB rules rather than as an investment company.

FAQ

Municipal Fund Securities questions

Is a 529 plan a mutual fund?

No. It invests contributions in mutual funds, but the interest the investor holds is a municipal fund security regulated by the MSRB.

Who regulates 529 plans?

The MSRB writes the rules; FINRA enforces them for broker-dealers that sell the plans.

What happens on a non-qualified 529 withdrawal?

The earnings portion becomes taxable and is generally subject to a penalty. The contributions themselves were made with after-tax money.
