Best Bank Account Bonuses November 2026: Up to $1,000

Here is the short version: the best bank bonus available to new savers in November 2026 pays up to $1,000 in cash, on top of a 4.30% APY that is guaranteed for 90 days. It comes from Western Alliance Bank’s high-yield savings account, opened through the Raisin savings marketplace, using promo code STACK. The Motley Fool’s November 1 bonus roundup lists the same tiers, and Raisin’s own offer page confirms the 90-day promotional rate and the September 1 to November 30 window. You need at least $10,000 to qualify for any bonus at all, and the full $1,000 requires $200,000 parked for 90 days, split between savings and a CD.

That is a genuinely good deal for someone who already has idle cash sitting in a low-rate account. It is a mediocre deal for someone who would have to scramble, borrow, or lock up emergency money to reach a tier. The difference between those two people is the whole article. Below is the bonus table, the exact qualifying rules, the worked math on what you actually earn after 90 days and after tax, and the Raisin catches that trip people up.

A quick note on timing: this offer’s sign-up window runs from September 1 to November 30, 2026. If you are reading this after November 30, the STACK terms may have changed or ended. Rates are variable by nature, and the 4.30% figure is a 90-day promotional rate, not a permanent one. Check the current terms before moving money. This is general information, not professional financial advice.

The headline offer: Western Alliance Bank via Raisin

Western Alliance Bank, Member FDIC, offers its high-yield savings account through Raisin, a marketplace that lets you open savings products at more than 100 partner banks and credit unions under one login. The November 2026 promotion, code STACK, works like this:

• Sign up as a new Raisin customer and enter code STACK at registration.
• Make your first deposit between September 1 and November 30, 2026.
• Deposit additional funds within 14 days of that first deposit if you want them to count toward the bonus tier.
• Keep the qualifying funds with Raisin partner banks for 90 days from the initial deposit date.
• The bonus is credited to your Raisin Cash Account within 30 days after you meet all the terms.

There is no minimum balance to keep the account open, no monthly fee from Raisin, and the account itself can be opened with as little as $1. But the bonus tiers start at $10,000, and that is the number that matters.

The bonus tiers, tier by tier

The Welcome Bonus depends on how much you deposit and hold:

On top of that, there is a Savings + CD Boost: if you split your qualifying balance between a savings account and a CD, keeping at least $1,000 in each category through the 90 days, you earn an extra bonus. The boost is $10 on a $10,000 deposit and $100 on a $200,000 deposit, which is how the headline “up to $1,000” is reached: $900 welcome plus $100 boost at the top tier, and $50 total at the entry tier.

Notice what the table is really telling you. The bonus rate is not flat. At $10,000 with the boost, $50 is 0.50% of your deposit for 90 days. At $200,000, $1,000 is also 0.50%. But in the middle, the tiers wobble: $100 on $25,000 is 0.40%, while $425 on $100,000 is 0.425%. The practical lesson is to check which side of a tier boundary your deposit lands on. If you have $24,000 to park, finding another $1,000 to cross into the $25,000 tier more than doubles your welcome bonus, from $40 to $100. If you have $49,000, another $1,000 doubles it again, from $100 to $200. Tier boundaries are where bonus-chasing actually pays.

The bonus-vs-rate math: what you really earn in 90 days

A bonus is only half the return. During the same 90 days, your money also earns interest at 4.30% APY, guaranteed for that period, before dropping to the standard variable rate, currently 4.00%. Here is the full 90-day picture at the two ends of the table, calculated with simple interest math (deposit × APY × 90/365):

Parking $10,000, split between savings and a CD:
– Interest at 4.30% for 90 days: about $106
– Total bonus (welcome $40 + boost $10): $50
– Total earned in 90 days: about $156
– That works out to roughly 6.3% on an annualized basis for the quarter — the 4.30% interest plus about 2.0 points from the bonus.

Parking $200,000, split between savings and a CD:
– Interest at 4.30% for 90 days: about $2,121
– Total bonus (welcome $900 + boost $100): $1,000
– Total earned in 90 days: about $3,121
– Annualized, again roughly 6.3% for the quarter.

Now compare that with doing nothing. The FDIC national average for savings accounts is 0.38%, and Raisin’s own comparison page lists big-name savings rates around 3.20% for Marcus, American Express, and Capital One as of late October 2026. At 0.38%, that same $10,000 earns about $9 in 90 days. At 3.20%, it earns about $79, with no bonus. The Western Alliance deal beats both by a wide margin over the quarter — but only if you actually hold the money for the full 90 days. Pull out early and the bonus disappears, leaving you with just the interest, which is still competitive but no longer special.

One more comparison matters for the top tier. If you already have $200,000 in cash, you might wonder whether chasing a $1,000 bonus is worth the hassle versus simply moving to the highest-rate account you can find. At 4.30% versus 4.40% elsewhere, the rate gap on $200,000 over 90 days is only about $49. The $1,000 bonus dwarfs it. For large balances, the bonus is the decision, not the rate. For small balances, the opposite is true: on $10,000, a $50 bonus is nice, but a full percentage point of APY difference would matter more over a full year than a one-time $50.

The after-tax math nobody puts in the headline

Bank bonuses are taxable. The IRS treats a cash bonus for opening a deposit account as interest income in most cases, reported on Form 1099-INT when the amount is $10 or more, and taxed at your ordinary income rate. That is different from credit card rewards earned by spending, which are generally treated as a rebate and not taxed. The bonus counts in the tax year it is credited to your account, not the year you opened the account — so a bonus that posts in January after a November sign-up lands on next year’s return.

Run the numbers before you celebrate:

Those figures are before state tax, which applies in most states. The $1,000 headline is really $780 at a 22% federal rate, or less once your state takes its share. That is still free money for cash you were holding anyway, but it is not $1,000 in your pocket. Set aside the tax slice when the bonus posts so next spring’s 1099-INT does not turn a windfall into a bill.

There is also a timing wrinkle worth knowing. Because the bonus posts up to 30 days after you complete the 90-day hold, a deposit made in early November may not produce a bonus until February. Plan for that lag, and do not count the bonus as available money until it actually lands.

The Raisin catches, stated plainly

Raisin is a marketplace, not a bank, and that structure comes with trade-offs that matter more than the bonus for some savers:

• One linked external account. You link a single outside bank account, and all money moves in and out through that account by ACH transfer. If your main bank changes, or you want to fund from a second account, you cannot just add another link on the fly.
• ACH only, no wires, no ATM, no branches. Deposits and withdrawals take one to three business days to settle. There is no debit card and no checkbook on these savings products. This is a parking spot for savings, not a spending account.
• Custodial structure. Your deposit sits in an omnibus custodial account at the partner bank and is eligible for FDIC insurance up to $250,000 per depositor at that bank, but you do not get a separate account number and routing number at Western Alliance itself. If you already hold other deposits at Western Alliance outside Raisin, check how the FDIC coverage adds up across both.
• New customers only, and one bonus per customer. If you already have a Raisin account, the STACK offer is not for you. The offer also cannot be combined with other Raisin bonus offers.
• The 90-day clock is strict. Only funds deposited within 14 days of your first deposit count, and they must stay put for 90 days from the initial deposit date. Dipping below your tier during the hold can cost you the bonus tier you were aiming for, so do not treat this account as your emergency fund during those three months.

None of these are deal-breakers for money you genuinely do not need for 90 days. All of them are deal-breakers for money you might need next week.

Who should take this deal, and who should skip it

Take it if: you have $10,000 or more sitting in an account paying under 3%, you will not need it for 90 days, you are comfortable with ACH-only access, and you are a new Raisin customer. The entry tier alone turns about $9 of national-average interest into about $156 over a quarter.

Consider it carefully if: you are near a tier boundary. Moving from $24,000 to $25,000, or $49,000 to $50,000, changes the bonus far more than the extra deposit itself earns. But never borrow money or raid an emergency fund to cross a boundary. A $60 bonus gain is not worth a cash-flow crisis.

Skip it if: you already have a Raisin account, you need instant access to the money, you want a checking account or debit card attached to the same balance, or your cash is already earning a comparable rate somewhere with terms you prefer. A bonus you cannot actually collect is worth zero, and an account structure you hate will cost you attention every time you need to move money.

How to claim it without tripping over the fine print

1. Confirm you are a new Raisin customer and that the STACK offer is still live. The window ends November 30, 2026.
2. Enter code STACK at sign-up, before you fund. Codes entered after the fact generally do not count.
3. Link the external account you actually want money to return to. Remember, it is the only one.
4. Make your first deposit, then complete any additional funding within 14 days so the full amount counts toward your tier.
5. If you want the boost, open a product in a second category (a CD alongside the savings account) with at least $1,000, within the same 14-day window.
6. Leave the money alone for 90 days from the initial deposit date. Set a calendar reminder for day 91, not day 89.
7. Watch for the bonus credit within 30 days after qualifying, and set aside the tax slice when it posts.

If you already read our October bank bonus roundup, this November offer is the same Western Alliance promotion in its final month, with the same tiers and the same 90-day hold. What changed is the clock: the sign-up window closes November 30, so this is the last call for STACK rather than a new deal. And if you are weighing this against other ways to make idle cash work harder, our guide to Treasury bills after tax compares a different low-risk parking spot, one whose interest is exempt from state tax.

Frequently Asked Questions

How much do I need to deposit to get any bonus?

At least $10,000, deposited and held for 90 days. Below that you still earn the account’s interest rate, but no welcome bonus and no boost.

When does the bonus actually arrive?

Within 30 days after you meet all the qualifying terms, which means after the full 90-day hold. A November deposit may therefore produce a bonus that posts in February, and it counts as income in the year it posts.

Is the 4.30% APY permanent?

No. It is a 90-day promotional rate. After 90 days the account earns the standard variable rate, currently 4.00%, which can change. The bonus is one-time; the rate after the promo period is what determines whether the account is worth keeping.

Are bank bonuses taxed?

Yes, generally as interest income. Banks usually report bonuses of $10 or more on Form 1099-INT, and the amount is taxed at your ordinary rate in the year it is credited. Credit card rewards earned by spending are treated differently and are generally not taxed, which is why a $300 bank bonus and a $300 card bonus are not worth the same after tax.

Can I withdraw my money during the 90 days?

You can withdraw savings, but doing so risks losing the bonus, since qualifying funds must be maintained for the full 90 days. Treat the deposit as locked for the quarter even though the account itself has no withdrawal penalty.

Is my money FDIC-insured through Raisin?

Deposits are held at the partner bank — in this case Western Alliance Bank, Member FDIC — and are eligible for FDIC insurance up to $250,000 per depositor at that bank. Raisin itself is not a bank. If you hold other deposits at the same bank outside Raisin, check your total coverage across both.
