Where to keep your tax reserve: your bank, or ExactSplit Wallet

The reserve only works if the money is somewhere you do not spend from. For most people that is a savings account at their own bank. For people who want it inside ExactSplit, there is now an optional wallet. Here is how the two compare, honestly.

The instruction nobody finishes

Every guide to quarterly taxes ends with the same instruction: put the money somewhere you will not spend it. It is good advice, and it is the part people most often skip, because it leaves the question of where entirely to you.

This post is about that question. The short answer is that a savings account at the bank you already use is the right place for most people, and nothing in ExactSplit needs you to do anything else. The longer answer is that some people want the reserve inside the same product that tells them how much it should be, and for them there is now an optional wallet.

It is also the part no software can do for you, and until recently it was the part ExactSplit handled least well. The dashboard could tell you precisely how much to move from each deposit and whether you had, but the where was left as an exercise. That was fine for people with a savings account already set up and a habit of using it. It was not fine for the larger group who meant to open one and never did.

What a reserve account needs

The requirements are simple. The account should be separate from the one you spend from, so the money is not visible every time you pay for something. Moving money into it should take seconds, because the reserve only works if each deposit is split while it is fresh. Moving money out should be easy on the day a payment is due and slightly annoying on every other day. And it should be insured, because this is money that already belongs to the IRS in all but name.

Interest is nice but secondary. At a few percent a year, the difference between accounts on a reserve that rarely exceeds a quarter's payment is small. Getting the money there at all is worth far more than where it earns an extra quarter of a point.

There is one more requirement people tend to discover the hard way: the account should be boring. A reserve that sits next to an investment account, or inside an app that also offers trading, is a reserve that gets borrowed from when the market looks good. The best reserve account is the one you forget about between deadlines.

A useful test: imagine the day before a quarterly deadline. You open your banking app to make the payment. Is the reserve sitting there, one tap away, clearly labelled, with no reason to hesitate? Or is it mixed in with the operating balance, where paying the IRS feels like paying from your rent? The first arrangement gets paid on time. The second gets paid late, or in part, or from a credit card.

Option one: your own bank

A savings account at your own bank meets every requirement. Transfers between accounts at the same bank are instant and free. The deposit is FDIC insured directly, up to the usual limits, with no intermediary. And ExactSplit tracks it through the same read-only connection it uses for everything else: pick it as the reserve account in settings and the dashboard compares its balance with what should be there, proposes a transfer when it falls behind, and confirms the transfer when the deposit lands.

If you already have one, use it. If you do not, opening one at the bank you already use is usually a five-minute job in their app. This remains the option we recommend first.

One practical note. Some banks cap the number of withdrawals from a savings account in a month, or charge for going over. With a reserve you move money in often and out four times a year, so the cap rarely bites. If your bank's savings account is awkward, a second checking account works just as well; ExactSplit does not care what kind of account it is, only that it is separate.

Whichever bank you choose, name the account for what it is. Most banking apps let you rename accounts, and an account called "Taxes, do not touch" is surprisingly effective. It sounds trivial. It is the cheapest behavioural nudge available, and it costs nothing to set up.

And if you run the business through a dedicated business checking account, the reserve can live beside it at the same bank. Transfers between the two are instant, the statements line up for your accountant, and the reserve stays out of your personal finances entirely.

Option two: ExactSplit Wallet

Some people would rather not open another account at their bank, or want the reserve to live in the same place as the number that governs it. For them we built ExactSplit Wallet. It is opened from a page inside the dashboard, it is optional, and it does one job.

You open it by reading a short disclosure and ticking a box. Nothing happens before you do. Identity verification follows, run by Whop, which provides the wallet; we never see your documents. Once verified, you can deposit from your bank and withdraw back to it. The wallet can do more, including sending money, converting to crypto, issuing cards and taking payments, but for the reserve we suggest using none of that. Money owed to the IRS should sit still.

Opening takes a couple of minutes. Verification usually completes in one sitting, though Whop may ask for a document if something does not match, and the page will show what it needs. Until verification is approved, the wallet can show you a balance of zero and nothing else. That is by design: no money moves into an account whose owner has not been confirmed.

The wallet has a home screen with your balance, actions and activity, plus sections for cards, payments, reports and settings if you want them. Everything that decides how much should be in the reserve lives on the main ExactSplit dashboard, where it always has; the wallet only holds it.

When your reserve falls behind, the main dashboard still proposes a transfer exactly as before. If the reserve is the wallet, you can make the transfer from the wallet page's deposit button rather than from your bank's app. The confirmation arrives the same way either way.

Who holds the money

The wallet is provided by Whop, Inc., a technology platform, through its financial institution partners, who hold the funds. ExactSplit is not a bank and never holds your money, in the wallet or anywhere else. Balances held with a partner bank may be eligible for pass-through FDIC insurance, which protects against the failure of that bank within the usual limits. It does not protect against the failure of Whop or of ExactSplit.

That is a real difference from a savings account at your own bank, where the insurance is direct and there is no intermediary, and it is the main reason we still recommend the bank first. After 2024, when the collapse of an intermediary left insured deposits at other fintech products inaccessible for months, it would be wrong to present the two as equivalent. They are not. The wallet is convenient; the bank is simpler.

We would rather say this plainly than bury it. If the insurance arrangement is the deciding factor for you, and for money you owe the IRS it is reasonable for it to be, the bank is the better choice. The wallet exists for convenience, and convenience is a legitimate reason to choose it, as long as it is chosen knowingly.

It is also worth knowing what happens if something goes wrong on a normal day rather than in a collapse. Whop's terms allow it and its partner banks to place a hold on funds for compliance or risk reasons. That is standard across the industry and it applies to your own bank as well, but it means a withdrawal can occasionally take longer than you expect. If a deadline is days away, move the money in good time.

What the wallet can and cannot do

Each visit to the wallet page receives a token that works only on your wallet and expires within minutes. What that token can do is fixed in code and checked by a test: the wallet's own features, and nothing that changes our platform's settings or acts as anyone else.

Your wallet balance is shown to you by Whop's components directly. Our servers do not store it. The only thing we store is the identifier of your wallet account, so we can find it again when you come back.

Opening the wallet also sends Whop your email address, so it can create your account. The disclosures page lists exactly what passes between us and Whop, and the privacy policy names Whop as a processor. If you close the wallet, the reserve tracking in ExactSplit carries on against whatever account you point it at next.

Choosing

Use your bank if you have a savings account there, if you want the simplest insurance arrangement, or if you would rather not add another company to the chain. Use the wallet if you want the reserve in the same place as everything else and are comfortable with the arrangement above. Either way the set-aside rate, the per-deposit split and the quarterly figures work identically, because they never depended on where the money sits.

What matters is that the money moves, every time, while the deposit is fresh. The place is a detail. The habit is the whole thing.

If you are unsure, start with the bank. Moving the reserve into the wallet later is a single transfer, and nothing in your history, your quarterly figures or your accountant's view depends on where it sat before.
