Most Tax Efficient Money Market Fund for NYC Resident

Submitted by CopperQuilt t3_127wfcd in personalfinance

What is the most tax-efficient Money Market Fund based on my marginal tax rates? I am a NYC resident. Also, if it makes sense for me to buy a MMF that is fed and or state/local exempt, do I need to do any calculations on my eventual tax forms or does the broker do that on the 1099? I currently am in SPAXX so I know I'll have at least some taxable interest from MMF when I file taxes next year

Fed: 24%

NY: 6.25%

NYC: 3.876%

Context: I have invested most of my emergency money in t-bills but want to stash a few thousand in money markets in case I need the money more quickly and don't want to risk selling t-bills on the secondary market

I believe the state income tax rate that corresponds to 24% federal in California is 9.3%.

When you are on Fidelity, click News & Research, Mutual Funds. Then screen the funds to only money market funds, Fidelity funds only, require less than 2.5k initial investment, you get 11 funds in the list.

Switch the view to "Daily pricing / yields" to see the 7-day yields. Sort by this 7-day yield.

Apply the "50% rule" (If a fund contains less than 50% of the thing that makes it tax-exempt, it is completely not tax-exempt). I know only FDLXX has >50% in US Treasury and US Gov Obligations. All of the funds above it in the list are dominated by Repurchase Agreements, which are not state tax exempt.

Then it's just a matter of multiplying the numbers. Example: 4.54% x (1 -0.24 -0.093) = 3.03%
