Is SPAXX interest income tax exempt? 1099INT shows $0 but 1099DIV shows distributions

SPAXX is Fidelity's Government Money Market Fund and is NOT tax exempt. The confusion comes from how it's reported. Money market funds technically pay dividends, not interest, which is why you're seeing it on the 1099-DIV instead of the 1099-INT. Since SPAXX invests primarily in government securities, the dividends it pays are considered "ordinary dividends" and are taxable as ordinary income on your federal return. The reason you see identical amounts in both "Ordinary Div" and "Div Distributions" columns is because all of the distributions are classified as ordinary dividends. If it were tax-exempt, you'd see amounts in the "Exempt-Interest Dividends" column of your 1099-DIV instead, and your brokerage would likely label it as something like "Municipal Money Market" rather than "Government Money Market.

I was in the same boat as you last year trying to figure out this exact SPAXX tax situation! I spent hours on the phone with my brokerage and reading through IRS publications until I finally tried https://taxr.ai which helped me understand how to properly report these dividends. Their system analyzed my 1099-DIV and pointed out that SPAXX dividends aren't tax-exempt - they're ordinary dividends that need to be reported on line 3b of Form 1040. What I found really helpful was uploading my 1099-DIV to their system and getting a clear breakdown of which money market funds generate taxable vs tax-exempt income. Turns out SPAXX specifically is taxable at the federal level, though some other money market funds that focus on municipal securities can be tax-exempt.

So I gave taxr.ai a try after my skeptical questions above. Actually impressed with how it handled my investment forms. It correctly identified my SPAXX dividends as taxable ordinary dividends and explained why they show up on the 1099-DIV instead of 1099-INT (apparently money market funds technically pay dividends even though we think of them as interest-bearing). The system flagged a mistake I was about to make - I was going to report these as qualified dividends which would have given me a lower tax rate, but it explained that money market dividends don't qualify for that preferential rate. Saved me from a potential audit flag! It also explained which of my other investments generated tax-exempt income (my municipal bond fund) versus taxable income. Way clearer than the cryptic descriptions on my brokerage statements.

If you're still having trouble figuring out your SPAXX tax situation, you might need to talk directly with the IRS. I was in the same boat last year and spent WEEKS trying to get through on their helpline. Always busy signals or 2+ hour wait times only to get disconnected. Finally found https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c - they basically call the IRS for you and then call you when they've got an agent on the line. Managed to get through to a real IRS person in about 40 minutes instead of the usual endless hold music. The agent confirmed exactly how SPAXX dividends should be reported and cleared up my confusion about why they weren't showing on my 1099-INT. She explained that money market funds technically pay dividends rather than interest, so they appear on the 1099-DIV even though we commonly think of them as interest-bearing accounts.

OK I have to eat my words about Claimyr. After posting my skeptical comment I decided to try calling the IRS myself about some SPAXX dividend questions and spent TWO HOURS on hold only to get disconnected. Was so frustrated I gave Claimyr a shot the next day. They called me back in about 35 minutes with an actual IRS agent on the line. The agent confirmed that SPAXX dividends are indeed taxable ordinary income that should be reported on line 3b of Form 1040, and explained why they show up on 1099-DIV instead of 1099-INT (which was my exact confusion). Honestly it was worth it just to save my sanity from the hold music. Will definitely use them again when I need to talk to the IRS about my tax questions.

Just to add another data point - I have both SPAXX and SPAXX: Cash Reserves in my Fidelity accounts. Both pay ordinary dividends that are taxable. The difference is that SPAXX (Fidelity Government Money Market) invests in government securities, while some other money market funds might invest in municipal securities which could potentially be tax exempt. If you want tax-exempt interest, look into funds with names like "Municipal Money Market" or similar. Those typically invest in municipal bonds which are exempt from federal taxes (and sometimes state taxes if you buy one specific to your state).

Sorry to come in late on this thread but I just want to make sure I'm understanding right. I have SPAXX in my Fidelity account and I got $329 in dividends last year according to my 1099-DIV. So I just put that on line 3b of my 1040 and pay regular income tax on it? Not the lower qualified dividend rate?

Just wanted to add some clarity for anyone still confused about SPAXX reporting. I work as a tax preparer and see this confusion every tax season. The key thing to remember is that SPAXX is structured as a mutual fund that invests in government securities, not a traditional bank savings account. That's why the income is technically "dividends" rather than "interest" - even though it functions like a savings account from your perspective. Here's what you need to know for your tax return: - Report the total from your 1099-DIV Box 1a (ordinary dividends) on Form 1040 line 3b - Do NOT include SPAXX dividends on line 3a (qualified dividends) - they don't qualify for the lower tax rate - The income is taxable at your ordinary income tax rates, just like wages or traditional interest If you want truly tax-exempt income, look for municipal money market funds (these will have "Municipal" or "Tax-Free" in the name). But remember, tax-exempt funds typically have lower yields to compensate for the tax advantage.
