Which money market fund pays you most in Alaska?
On today’s yields, VMSXX leaves a single filer earning $150,000 a year in Alaska the most after tax: 3.34% a year, as good as a savings account paying 4.39%.
How Alaska taxes each fund
Alaska has no income tax, so it takes nothing from any fund. Federal tax decides the answer: government and Treasury funds pay it, with the 3.8% on investment income above $200,000 single or $250,000 joint, and municipal funds don't.
Today VMSXX yields 3.34% and VMRXX 3.80%, so the muni fund comes out ahead once federal tax takes more than 12.1% of the interest.
| Fund | Federal | State | Yield |
|---|---|---|---|
| VMFXX Government | Taxed | No income tax | 3.79% |
| VMRXX Government | Taxed | No income tax | 3.80% |
| VUSXX Treasury | Taxed | No income tax | 3.80% |
| VMSXX National muni | Free | No income tax | 3.34% |
| VYFXX New York muni | Free | No income tax | 3.30% |
| VCTXX California muni | Free | No income tax | 3.06% |

Asked about Alaska
Which money market fund is best in Alaska?
On Vanguard's yields for October 1, 2026, it is VMRXX for a single filer earning $60,000 a year. It is VMSXX for a single filer earning $150,000 a year and a married couple filing jointly on $400,000. The answer moves with yields and with your bracket, which is why the calculator works it out on the day.
Are Treasury money market funds taxed in Alaska?
Not by the state: Alaska has no income tax. A Treasury fund like VUSXX is still taxed federally.
Does Alaska tax municipal money market funds?
No. Alaska has no income tax, and a muni fund's income is free of federal tax too, so VMSXX keeps all of its yield.
What is the tax-equivalent yield in Alaska?
It is what a savings account, taxed federally, would have to pay to leave you as much as a fund does. For a single filer earning $150,000 a year in Alaska, VMSXX at 3.34% is as good as 4.39% in savings today.
