VBIL
Vanguard 0-3 Month Treasury Bill ETF
stock NASDAQ ETF

Yes they are all, or almost all, state tax exempt - 95.14% state tax exempt for 2025 taxes. VBIL was 100% state tax exempt. Treasury bond interest is guaranteed 100% state tax exempt and the info to claim that is on the 1099. Mut fund and ETF dividends state tax exemption is not on the 1099 and require a manual calculation and extra entry in tax software. It's still not hard.
It varies from year to year and isn't known until the end of the year. Ca/NY/? also have a requirement that 50% of the dividends have to come from federal obligations for each quarter of the year to be state tax exempt. Some MMFs will pass that requirements some years.
State tax exemption can increase the taxable equivalent yield significantly.

I'd move the entire emergency fund into sgov. Shorter duration. I wouldn't bother trying to maximize returns on the emergency fund. Sure, you probably will do better with SHV with a rate cut, but you don't know that for sure and the whole point of the E-fund is you need to be able to cash out tomorrow without getting screwed if rates rise (however unlikely).
I'd replace sgov with Vangaurd's VBIL. Same duration but cheaper 0.06 ER. Saves you about $30 bucks per 100k. It's a free lunch every year so why not?
401k looks good.
Roth looks good too. One caveat; if you believe SCG is a drag, something to be avoided, you may want to snip the small cap tails off your core indexes and fully address them with Avantis ETFs. ie pair VOO or SCHK with AVUV instead of VTI.
The international allocation is light. But 20% is more than a lot of people. It's acceptable. Vanguard would recommend you double it to 40%. They are big on the classic investing ideas where P/E ratios matter. Lot's of people shit on Vanguard for "being wrong" on expected returns for the past several years. But loading up on value is not about winning today, it's about loading up the spring cheaply for several years and then experiencing an incredible era of out-performance when the spring is sprung.

Others have covered not to invest money you may need within the next 5 years. One thing I'd add is you could consider moving the funds from the HYSA to a treasury ETF like VBIL or SGOV as the interest may be more tax advantaged than in the HYSA.

VBIL

VBIL is government treasuries and it changes the lowest fee

Exactly, I chose VBIL. It’s a little bit smaller expense than SGOV but the yields are the same.

$100k to VT for growth with total global market exposure, ultimate set and forget, self market weight adjusting. $90k to QQQI/SPYI 50/50 for income pulls $11,925 a year, $993.75 a month. $10k into Vbil for emergency fund pulls $354 a year, $29.50 a month. ***This is based on current rates. VT also pays a div quarterly, last year was 0.3852, 0.5947, 0.4781, and 1.1152 per share, December has a track record of the highest. At current price $100k would get around 683 shares. And for just for a visual example using last year numbers 683 shares: March $263.09, June $406.18, Sept $326.54, Dec $761.68. If you honestly don't need the divs, $190k into VT, VTI, or VOO is perfectly fine, let it grow for 20-30 years, and keep $10k EF in VBIL.

You are not comparing the correct yields.
- The SEC yield for VMFXX is 3.59%
- The SEC yield for VBIL is 3.54%

VBIL is basically vanguard version of SGOV?

\> so I was thinking of asking Fid to switch to FDLXX which states it's around 3.9%.
FDLXX is not available as core position / cash sweep, so don't waste your time ... if you want to buy manually something resulting in higher yield there many options , to name few of them
1. Fidelity's own MMF ( FLDXX and many noticeably better than FDLXX, specifically when you do not care about state taxes ... plus they will be self-liquidating, but manual purchases ... procuring some might involve one time actions that you need to google for )
2. non Fidelity's MMF ( you can buy VUSXX for example in Vanguard and transfer shares to Fidelity - so manual buy with extra move to ACATS in, dividends reinvestment are free ... not self liquidating but buy sell does not generate possible wash sales, etc )
3. ETFs like SGOV, VBIL, etc - manual buy ( in Fidelity, no need for an extra step like with VUSXX, manual sale, might result in wash sales if you do not watch what you do, extra tax reporting as you buy and sell ETFs )
4. buy/sell treasuries directly, can use auto-roll, better to do in separate dedicated account
etc, etc, etc
PS: most of what mentioned above involve stuff using treasuries in some form or shape just because it is as close to FDIC insured as possible ... but certainly if you want more risk / reward you can go for ultra-short bonds, etc - but that will become already not exactly cash position
