SGOV vs HYSA: Which Earns More After Tax in 2026?

Choosing between the iShares 0–3 Month Treasury Bond ETF (SGOV) and a high-yield savings account comes down to one number most people overlook: your state income tax rate. Both products hold ultra-safe, short-term assets and pay yields that track the federal funds rate. Before tax, a top savings account can pay more than SGOV. After state tax, the picture often flips, because Treasury-bill interest is exempt from state and local income tax under 31 U.S.C. § 3124, while savings-account interest is taxed like wages.

That single exemption can be worth $100 to $200 a year on a $50,000 balance for someone in California, New York, or any state with a marginal rate above roughly 5 points. In no-income-tax states like Texas and Florida, the exemption is worthless and the decision simplifies to whichever option pays the higher rate.

Beyond yield, the two products differ on liquidity, insurance, and convenience. A savings account gives you same-day access, FDIC coverage, and zero paperwork. SGOV requires a brokerage account, settles in one business day after you sell, and asks you to enter a tax-form percentage each January. This guide walks through the full SGOV vs HYSA comparison (yield, taxes, access speed, safety, and rate-cut behavior) so you can decide which mix fits your cash.

Quick answer

Your state income tax rate decides this one, not the headline yield. SGOV pays about 3.55% and that income is exempt from state and local tax; a high-yield savings account may pay more before tax but owes state tax like ordinary income. Divide SGOV's yield by (1 minus your marginal state rate) to get its tax-equivalent yield, then compare that number to the best savings APY you can open today. In a no-income-tax state the math is simple: take the higher pre-tax rate. In California, New York, or any state above roughly a 5% marginal rate, SGOV usually keeps more of your cash after tax even when its sticker yield looks lower. Most savers do best with a hybrid: one month of expenses in a savings account for instant access, the rest in SGOV.

SGOV vs HYSA: Side-by-Side Comparison

Before diving into specifics, here is the operational snapshot. Every difference that matters day-to-day is in this table.

The yield column alone doesn't settle the debate. The state-tax row is where money changes hands, as we'll show below.

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 a 0.09% annual expense ratio (already netted out of the quoted yield), and distributes interest as a monthly dividend. The share price follows a sawtooth pattern, climbing about 30 cents over the month as interest accrues, then dropping back when the dividend pays out. Bills this short carry no meaningful price risk, which is why the fund behaves more like a cash instrument than a bond fund.

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 makes it the default pick for most savers, though USFR's weekly reset reflects Fed moves fastest in either direction.

One note on fees: 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 savings account you compare against. As of early June 2026, with the Fed funds target at 3.75%:

Before tax, SGOV sits mid-pack: ahead of Ally by roughly $275 a year on $50,000, behind Marcus by about $50, and behind the market leaders by over $400. If the comparison ended there, a rate chaser would just pick the top savings account. Taxes change the ranking.

How the State-Tax Exemption Changes the Math

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

A Worked Example

Consider a saver named Maria, 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. Maria keeps $1,775 before federal tax (which both options owe equally).

Marcus savings at …: … of interest. California tax at 9.3%: ~$158. Maria keeps ~$1,542.

SGOV wins by roughly $233 a year despite a similar 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%. Maria needs a savings account paying at least 3.91% before the bank account genuinely pays more. Only the top sliver of the market clears that bar.

The effect scales with your state rate. A New York City resident facing roughly 10.9 points state plus 3.9 points city tax at top brackets needs a savings account near 4.20% to match SGOV, a rate 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%.

Dollar-Impact Ladder by Balance

Here is how the after-tax gap plays out across common balance tiers for a California saver at 9.3%, comparing SGOV at 3.55% to a … savings account:

At $100,000 the gap covers a nice dinner out every month, or a year of streaming subscriptions. In a no-tax state, these columns are identical and SGOV's lower pre-tax yield means it loses.

How Fast Can You Actually Get the Money?

This is the savings account'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 (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 savings-account layer in a hybrid setup covers. For help sizing that layer, see our emergency fund guide.

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.

For reference, the 3-month Treasury currently yields 4.30% and the best high-yield savings rate on our tracker pays 4.20% APY. See current savings rates for where your bank sits. Here is how savings yields have tracked recently:

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 rather than chasing savings-account rates.

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.

The "Tax-Free" Hook: Marketing vs. Reality

Banks and brokerages both play marketing games with SGOV vs HYSA positioning. Savings accounts advertise a big APY number in bold, but the fine print rarely mentions that your state takes a cut. Meanwhile, Treasury-ETF promoters lean on the phrase "tax-free interest," which is misleading: the interest is still fully taxable at the federal level. Only the state-and-local slice disappears.

Here is the reality check:

• Savings-account hook: "Earn 4.20% APY!" True, but after a 9-point state tax rate your effective yield drops by roughly 35–40 basis points.
• SGOV hook: "Tax-free Treasury income!" Only state-tax-free. Federal tax still applies at your ordinary income rate, and you need to enter a line item on your state return to actually claim the break.

Neither product is lying, but both are telling the half of the story that looks best. The honest comparison is always after-tax yield at your specific state rate, which is why the tax-equivalent yield formula (SGOV yield ÷ (1 − state rate)) is the only number worth memorizing.

Where SGOV Wins (Pros)

• After-tax yield in high-tax states. In any state with an income tax rate above roughly 5 points, SGOV's Treasury exemption usually produces more take-home income than a mid-tier savings account.
• No $250,000 cap. Treasury obligations carry the full faith and credit of the U.S. government with no balance limit, unlike FDIC coverage.
• No rate games. SGOV's yield is set by T-bill auctions, not a bank marketing team. No teaser rates, no loyalty penalties, no quiet cuts after the first six months.
• Consolidation. If you already use a brokerage for investing, SGOV keeps your cash in the same place instead of adding another institution.

Where SGOV Falls Short (Cons)

• Slower access. Two to three business days to spendable cash, versus same-day at many banks.
• Brokerage required. You need a Fidelity, Schwab, Vanguard, or similar account, an extra step if you don't already have one.
• Tax-filing burden. You must manually enter the government-obligation percentage on your state return or lose the exemption entirely.
• Worthless in no-tax states. If you live in Texas, Florida, or one of the other seven no-income-tax states, the exemption saves you nothing and a top savings account likely pays more.
• Expense ratio drag. The 0.09% fee is small but nonzero; a savings account charges nothing.

SGOV vs HYSA: How to Decide in 60 Seconds

Choose a high-yield savings account if...

• You live in a no-income-tax state, where the exemption is worth nothing and the best savings rate likely beats SGOV outright.
• You can lock in a top-of-market rate (around 4.20%) that clears your tax-equivalent threshold.
• You want same-day access, no brokerage account, and zero settlement mechanics.
• Simplicity at tax time matters more than roughly $100–$200 a year.

Choose SGOV if...

• You pay a state income tax rate of roughly 5 points 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 fewer institution.
• You're tired of savings-account 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 savings account, the remainder in SGOV. For example, consider David, a New York saver with $50,000 and $6,000 sitting in the savings account. He gives up about $20 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. For more on sizing a cash reserve, read our emergency fund guide.
