If you want to split one savings account into labeled pots for different goals, the banks that offer sub accounts are mostly digital: Ally Bank calls them Buckets, SoFi calls them Vaults, Chime calls them Savings Goals, and Sallie Mae’s SmartyPig is built entirely around goal-based saving. Capital One 360 gets you a similar result by letting you open multiple separate savings accounts under one login. Most large traditional banks don’t offer true sub accounts at all; they offer goal-tracking overlays on an undivided balance, with PNC’s three-bucket Virtual Wallet as a partial exception.
What a Sub Account Actually Is
A sub account is a virtual label inside a single savings account, not a separate account. The bank sees one account with one balance. You see named segments like “Emergency Fund,” “Vacation,” or “New Car.” The money never leaves the main account; the bank just tracks how much you’ve assigned to each label.
Because they’re internal bookkeeping, sub accounts don’t have their own routing or account numbers. You can’t direct-deposit a paycheck into a specific bucket or write a check against one. To spend from a bucket, you move the money back to your main balance first, then withdraw or transfer. That extra step is part of the appeal: enough friction to keep you from raiding your vacation fund for takeout.
Online Banks With True Sub Accounts
Ally Bank: Savings Buckets
Ally is the best-known name here. You can create up to 30 buckets inside one Savings Account, each with its own name, target amount, and target date.1Ally Financial. What Are Ally Bank’s Savings Buckets and Boosters? Ally also offers Boosters, which include recurring transfers and round-up tools that automatically funnel money into a chosen bucket. The whole combined balance earns Ally’s high-yield APY.
SoFi: Vaults
SoFi’s checking and savings product includes Vaults, which work the same way as Ally’s buckets. You name each vault and set a goal. Members with qualifying direct deposit earn a higher APY on savings including vault balances; without direct deposit, the rate drops significantly, so SoFi works best if you route your paycheck through it.
Chime: Savings Goals
Chime’s Savings Goals feature lets you separate money into labeled categories within one savings account. Chime also offers automatic round-ups on debit card purchases, with the spare change deposited to savings.
SmartyPig by Sallie Mae
SmartyPig is built specifically around goal-based saving. Each goal has a target amount and timeline, and the account tracks your progress toward it. It currently pays one of the higher APYs among accounts with built-in goal features. It’s a good fit if goal-tracking is what you care about and you don’t need a full banking relationship.
Capital One’s Multi-Account Alternative
Capital One 360 takes a different route. Instead of virtual buckets inside one account, Capital One lets you open multiple separate 360 Performance Savings accounts under one login. Each has its own balance, its own account number, and its own nickname, all managed from a single dashboard. Because they’re technically distinct accounts, each one can receive direct deposits or external transfers independently, which buckets cannot.
The tradeoff is paperwork. Each account is a real account on your records, and closing one you no longer need takes more steps than deleting a bucket. If you want true separation where money assigned to one goal can’t accidentally get swept into another, this structure delivers it.
Traditional Banks: Goal Trackers, Not Sub Accounts
Most large brick-and-mortar banks don’t offer true sub accounts. They offer goal-tracking overlays: digital tools that let you set targets and watch progress bars, without actually partitioning your money.
Bank of America’s Life Plan is the usual example. It helps you identify priorities and set steps toward them, but it doesn’t carve your savings into isolated segments.2Bank of America. Over 10 Million BofA Clients Use Life Plan to Pursue Financial Goals Through Personalized Digital Experience Your money sits in one undivided pool, and the app shows you a progress bar against it.
PNC Bank’s Virtual Wallet is closer to real separation. It bundles three accounts, Spend, Reserve, and Growth, under one product, giving you genuine partitioning between everyday money and longer-term savings. The structure is fixed at three categories, though. If you want custom goals or more than three, an online bank’s bucket system will serve you better.
How Interest Works Across Buckets
Because sub accounts divide a single savings account, the entire aggregated balance earns interest at the same APY. If your account pays 3.30% APY and you have $5,000 split across four buckets, interest is calculated on the full $5,000, not separately on each bucket’s share. The interest is credited to the main account balance, and most banks don’t report how much interest each individual bucket “earned.”
FDIC Insurance Does Not Multiply With Buckets
Sub accounts do not increase your FDIC coverage. The FDIC insures $250,000 per depositor, per insured bank, for each ownership category.3FDIC.gov. Understanding Deposit Insurance Buckets are internal labels within one savings account, not separate ownership categories, so the FDIC treats them as one combined balance. $200,000 spread across ten buckets at one bank is $200,000 in FDIC-insured savings, not ten separately insured pots.
Ownership categories that do qualify for separate coverage include single accounts, joint accounts, certain retirement accounts like IRAs, and trust accounts.4Federal Deposit Insurance Corporation (FDIC). Your Insured Deposits If your savings at one bank approach $250,000, opening a joint account or an account at a second FDIC-insured bank adds coverage. More buckets at the same bank do not.
Buckets Don’t Protect Money From Your Own Bank
Labeling $3,000 as “Emergency Fund” feels like putting it in a safe, but your bank doesn’t see it that way. If your checking account at the same bank goes negative, the bank can pull money from your savings, including from any bucket or vault, to cover the shortfall. This is called the right of offset, and it’s built into the account agreements you signed when you opened the account.
Many banks also offer overdraft sweep arrangements that automatically tap savings to cover checking overdrafts. The bank’s agreement spells out what triggers a sweep, how much transfers, and what fees apply. A sweep can drain a bucket you were carefully building, without any additional authorization from you beyond the original agreement. If overdraft protection matters to you, read the sweep terms carefully; your labeled buckets offer no legal protection against these transfers.
Withdrawal Limits
The federal six-withdrawal-per-month cap on savings accounts was eliminated in April 2020, and as of 2026 there are no plans to reinstate it. Many banks still enforce their own limit, often six electronic transfers per month, as a matter of bank policy.
Banks that keep this limit typically count online transfers, mobile transfers, and automatic sweeps toward the cap, while ATM withdrawals and in-person transactions usually don’t count. Exceeding the limit can trigger fees in the range of $5 to $15 per extra transaction, depending on the bank. Before choosing a bank for sub accounts, check whether it still enforces a monthly cap, because moving money between buckets and checking can burn through those transfers fast.
Tax Reporting
At tax time, your bank issues a single Form 1099-INT for the whole savings account, not one per bucket. The IRS requires the form when a bank pays you $10 or more in interest during the year, and the account number field corresponds to the parent account.5Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID You get one lump interest figure. If you want to know how much interest came from your “Wedding Fund” versus your “Tax Payments” bucket, you’ll need to calculate it yourself from each bucket’s average balance over the year.
The interest is taxable as ordinary income in the year it’s earned, regardless of which bucket holds it or whether you withdrew it. There’s no special tax treatment for money in a goal-based bucket.
Setting One Up
Setup is nearly identical across every bank that offers the feature. Open the mobile app, go to your savings account, and look for Buckets, Vaults, Goals, or a similar label. Create a new one, name it, and optionally set a target amount and date. The app will calculate how much you need to save per week or month to hit the goal on time.
Fund the bucket with an instant internal transfer from your main balance, then set up recurring automatic transfers: a fixed weekly amount from checking, a percentage of each direct deposit, or round-ups on debit card purchases, depending on what the bank supports. Automation is the most valuable part. People who transfer money to savings manually do it inconsistently; people who automate tend to hit their targets.
When you reach a goal or decide to repurpose the money, close the bucket and the funds flow back to your main savings balance instantly. You can rename buckets, adjust targets, or delete them at any time, with no penalty, no waiting period, and no paperwork.
