SGOV vs HYSA 2026: After-Tax Yield, Liquidity, and Safety Compared — June 2026

The Bottom Line

In a no-income-tax state, pick whichever pays more before tax. In a high-tax state, SGOV usually wins after tax unless your HYSA sits at the very top of the market. SGOV yields about 3.55% and its interest escapes state income tax; a California saver at a 9.3% marginal rate would need a HYSA paying 3.91% to match it. The tradeoffs: no FDIC insurance (direct Treasuries instead), a brokerage account requirement, and two to three business days to spendable cash. The hybrid most cash-heavy savers land on: one month of expenses in a HYSA, the rest in SGOV.

Key Facts — SGOV vs HYSA comparison

1.SGOV 30-day SEC yield: ~3.55% (June 4, 2026). Expense ratio 0.09%, already netted out of the yield.
2.HYSA range, June 2026: roughly 3.10% (Ally) to ~4.10% at the top of the market; Marcus pays 3.65%.
3.T-bill interest is exempt from state and local income tax. HYSA interest is fully taxable at both levels.
4.On $50,000, a California saver at 9.3% keeps about $1,775 from SGOV vs about $1,655 after state tax from a 3.65% HYSA, a $120/year edge for the ETF.
5.SGOV settles T+1 and needs a brokerage account; plan 2-3 business days to cash. HYSAs are FDIC-insured with 0-3 day transfers.

What is SGOV, and how does it pay you?

SGOV is the iShares 0-3 Month Treasury Bond ETF. It holds a rolling portfolio of Treasury bills maturing within three months, charges 0.09% per year, and pays the interest as a monthly dividend. The share price follows a sawtooth, climbing about 30 cents over the month as interest accrues and dropping back when the dividend pays out. Bills this short carry no meaningful price risk.

Two siblings deserve a mention. BIL (SPDR 1-3 Month T-Bill ETF) does nearly the same job for a higher 0.14% fee, yielding about 3.50%. USFR (WisdomTree Floating Rate Treasury Fund) holds floating-rate Treasury notes whose coupons reset weekly, charges 0.15%, and yields about 3.60%. SGOV's lower fee settles it for most savers, though USFR's weekly reset reflects Fed moves fastest, up or down.

One note on the fee: older articles still cite a 0.07% net figure from an iShares fee waiver, but that waiver lapsed in mid-2024. The current number is a flat 0.09%.

Which pays more before tax?

Depends on which HYSA. As of early June 2026, with the Fed funds target at 3.50% to 3.75%:

Option	Yield	Annual income on $50,000
Top-of-market HYSA	~4.10%	$2,050
Marcus HYSA	3.65%	$1,825
USFR	~3.60%	$1,800
SGOV	~3.55%	$1,775
BIL	~3.50%	$1,750
Ally HYSA	3.10%	$1,550

Before tax, SGOV sits mid-pack: ahead of Ally by $225 a year on $50,000, behind Marcus by $50, behind the market leaders by $275. If the comparison ended there, a rate chaser would just pick the top HYSA. Taxes change the ranking.

How does the state-tax exemption change the math?

Interest on U.S. Treasury obligations is exempt from state and local income tax under federal law; HYSA interest gets taxed like wages. In the nine states with no income tax, this section changes nothing. Everywhere else, it can flip the ranking.

Work through a California resident in the 9.3% state bracket (which starts around $73,000 of single-filer taxable income) holding $50,000 of cash for a year:

SGOV at 3.55%: $1,775 of dividends. California tax: $0, because the income comes from Treasury bills. Keep $1,775 (before federal tax, which both options owe equally).

Marcus HYSA at 3.65%: $1,825 of interest. California tax at 9.3%: $170. Keep $1,655.

SGOV wins by about $120 a year despite the lower headline yield. The cleaner way to see it is tax-equivalent yield: divide SGOV's 3.55% by (1 − 0.093) and you get 3.91%. A Californian in that bracket needs a HYSA paying at least 3.91% before the bank account genuinely pays more. In June 2026, only the top sliver of the market clears that bar; a 4.10% account keeps $1,859 after state tax and beats SGOV by about $84.

The effect scales with your state rate. A New York City resident facing roughly 10.9% state plus 3.9% city tax at top brackets needs a HYSA near 4.20% to match SGOV, which nothing mainstream currently pays. A Texan or Floridian needs only 3.55%, which several banks beat. Your marginal state rate is the single number that settles this comparison.

One refinement: the exemption applies to the portion of fund income derived from U.S. government obligations, which SGOV reports each January and which has historically run well above 95%.

How fast can you actually get the money?

This is the HYSA's strongest card. A savings account moves money to checking same-day within the same bank, or in one to three business days by ACH externally.

SGOV takes three steps: sell the shares (instant during market hours), wait for T+1 settlement, then ACH the cash to your bank. Call it two to three business days door to door, longer over a weekend; a Friday-evening emergency might not see cash until Wednesday.

In practice the gap matters less than it sounds. Drop-everything expenses, like a car repair or an emergency flight, usually go on a credit card first, and the statement won't close before your SGOV proceeds land. The case where the delay truly hurts, a wire needed within 24 hours, is rare and is exactly what the HYSA layer in a hybrid setup covers.

What happens when the Fed cuts?

Both yields fall; the difference is timing. T-bill markets price in expected Fed moves weeks ahead, so SGOV's yield drifts down before a widely expected cut even happens. Bank rates move on committee schedules: some banks trim within days of a cut, others hold for a month or more to attract deposits.

With futures markets pricing two cuts over the coming year, expect both yields to grind lower into 2027. Neither product locks anything in. To freeze today's rate on money you won't need for a year or more, see our CD ladder vs HYSA vs T-bills guide.

Is SGOV safe without FDIC insurance?

SGOV swaps one kind of safety for another of essentially equal strength. FDIC insurance protects you from a bank failing, up to $250,000, with the federal government behind the guarantee. SGOV holds Treasury bills directly, obligations of that same government, with no bank in the middle and no $250,000 cap. For sums above the FDIC limit, Treasuries are arguably the cleaner arrangement, which is why corporate treasurers park cash in bills.

What SGOV adds is paperwork: a brokerage login, a settlement schedule, a 1099-DIV, and a state-return adjustment to claim the exemption. None of it is hard, but a plain savings account asks nothing of you at all.

Watch Out:

The state-tax exemption is not automatic on your return. Tax software asks what percentage of each fund's dividends came from U.S. government obligations, and if you skip the question, you pay state tax you don't owe. iShares publishes the figure each January. California, New York, and Connecticut add a 50% asset test that SGOV passes easily but some bond funds fail; confirm your own state's rules.

Choose a HYSA if...

You live in a state with no income tax, where the exemption is worth nothing and the best HYSA rate likely beats SGOV outright
You can get a top-of-market rate (around 4.10%) that clears your tax-equivalent threshold anyway
You want same-day access, no brokerage account, and zero settlement mechanics
Simplicity at tax time matters more to you than roughly $100-$200 a year

Choose SGOV if...

You pay a state income tax rate of roughly 5% or more, where the exemption usually flips the after-tax ranking
Your cash exceeds $250,000 and you'd rather hold government obligations directly than juggle FDIC limits across banks
You already run your finances through a brokerage and prefer one less institution
You're tired of HYSA rate games: teaser rates, loyalty penalties, and quiet cuts that T-bill auctions don't play

Use both if...

You want yield without giving up the instant layer. The standard hybrid: one month of expenses in a HYSA, the remainder in SGOV. On a $50,000 fund with $6,000 sitting in the HYSA, a Californian at 9.3% gives up about $14 a year of after-tax yield on that slice in exchange for never waiting on a settlement. That is cheap insurance, and it is the setup we'd suggest for most readers in high-tax states.

What to do next

What to Do Now

Compute SGOV's tax-equivalent yield for your situation: 3.55% divided by (1 minus your marginal state rate). Compare that to your current HYSA APY.

If the ETF wins, buy SGOV in a brokerage account at Fidelity, Schwab, or Vanguard; commissions are $0 and the minimum is one share (~$100).

Keep one month of expenses in your HYSA before moving the rest, so a same-day need never depends on settlement timing.

Each January, enter the iShares U.S. government source income percentage in your tax software so the state exemption actually lands.

For cash you won't touch for 12+ months, compare locking a rate instead, since both SGOV and HYSA yields will follow the Fed down.

Key Takeaways

✦SGOV yields ~3.55% (0.09% expense ratio already deducted); HYSAs run 3.10%–4.10%, with Marcus at 3.65%.
✦T-bill interest is exempt from state and local income tax; HYSA interest is not. That exemption is the entire case for SGOV.
✦For a Californian at 9.3%, SGOV's 3.55% equals a taxable 3.91%. On $50,000 it keeps ~$1,775 vs ~$1,655 from a 3.65% HYSA.
✦SGOV is not FDIC-insured but holds 0-3 month Treasuries directly, with no $250K ceiling.
✦Liquidity is the tradeoff: 2-3 business days from sale to spendable cash, vs 0-3 days for a HYSA.
✦The hybrid that fits most savers in taxed states: one month of expenses in a HYSA, the rest in SGOV.

Frequently Asked Questions

Which pays more right now, SGOV or a high-yield savings account?

Before tax, it depends on which HYSA. SGOV's 30-day SEC yield is about 3.55% (as of June 4, 2026). HYSAs range from roughly 3.10% (Ally) through 3.65% (Marcus) up to about 4.10% at the top of the market. After state income tax, SGOV gains ground: in California at a 9.3% marginal state rate, SGOV's 3.55% is equivalent to a fully taxable 3.91%, which beats every mainstream HYSA except the very highest payers.

Is SGOV FDIC-insured?

No. FDIC insurance covers bank deposits, and SGOV is an ETF, not a deposit. Instead of insurance, SGOV holds Treasury bills maturing in zero to three months, which are direct obligations of the U.S. government. The credit risk is the same federal credit standing behind FDIC itself. The practical risks are different ones: a brokerage step between you and your cash, and a NAV that fluctuates by small amounts within each month.

How fast can I get money out of SGOV?

Plan on two to three business days to spendable cash. Selling shares executes instantly during market hours, the trade settles the next business day (T+1), and the ACH transfer from your brokerage to your bank typically takes one to two more days. Some brokerages with linked debit cards or checking features shorten this. A HYSA gets money to an external bank in zero to three days and same-day within the same bank.

Why is T-bill interest exempt from state tax?

Federal law (31 U.S.C. § 3124) bars states from taxing interest on U.S. government obligations. Treasury bill income is still fully taxable at the federal level, but states and cities cannot touch it. SGOV passes this through: the fund reports each year what percentage of its dividends came from U.S. government obligations (typically well above 95% for SGOV), and that portion is exempt on your state return.

What about BIL and USFR instead of SGOV?

All three hold short-term Treasuries and behave similarly. SGOV (0-3 month T-bills) charges 0.09% and yields about 3.55%. BIL (1-3 month T-bills) charges 0.14% and yields about 3.50%. USFR holds floating-rate Treasury notes that reset weekly, charges 0.15%, and yields about 3.60%. SGOV's lower fee makes it the default pick; USFR's floating-rate structure tracks Fed moves fastest in both directions.

What happens to SGOV's yield when the Fed cuts rates?

It falls, and usually before the cut itself, because T-bill yields price in expected Fed moves weeks ahead. HYSA rates fall too, but banks move on their own schedule, sometimes lagging a cut by weeks, sometimes front-running it. Over a full cutting cycle the two end up in roughly the same place. Neither product protects you from falling rates; for that you need to lock a CD or longer Treasury.

Is there a minimum to invest in SGOV?

One share, currently around $100, and many brokerages (Fidelity, Schwab, Robinhood) allow fractional shares for less. There are no account minimums at major brokerages, no monthly fees, and trading commissions on ETFs are $0 at every mainstream broker. The only ongoing cost is the 0.09% expense ratio, about $45 per year on a $50,000 position, which is already reflected in the quoted yield.

Should I keep my whole emergency fund in SGOV?

Most people shouldn't. A common and sensible hybrid keeps one month of expenses in a HYSA for instant access and holds the rest in SGOV for the after-tax yield. The HYSA layer covers anything that genuinely cannot wait two or three business days; in practice, true same-hour emergencies are usually charged to a credit card and paid off when the transfer lands.
