The number in your bank account is not your cash position. Some of that balance was collected on behalf of a tax authority, some belongs to a customer who has not received anything yet, and some is held by a processor against future chargebacks. Restricted cash is money sitting in your operating account that has already been claimed by someone else, and in a service or retail business it routinely accounts for 10% to 25% of the balance. Forecasts that start from the bank balance start from a number that is too high.
What Counts as Restricted Cash in a Small Business
Restricted cash is any balance in your possession that is legally or contractually committed to a third party before it is committed to you. It is not an accounting abstraction. Every category below leaves the account on a schedule you did not set.
| Category | Whose money it is | When it leaves | Common in |
|---|---|---|---|
| Sales tax or VAT collected | The state or revenue authority | Monthly or quarterly filing date | Retail, ecommerce, hospitality |
| Payroll tax withheld | The IRS and state agencies | Monthly or semiweekly deposit schedule | Every employer |
| Customer deposits and prepayments | The customer, until you deliver | Consumed as work is performed, or refunded | Construction, manufacturing, events |
| Client trust and retainer balances | The client | Drawn down against billed work | Legal, agencies, professional services |
| Merchant rolling reserve | The payment processor | Released on the processor’s schedule, often 90 to 180 days | Ecommerce, subscription, high-risk categories |
| Unredeemed gift cards and credits | The customer | On redemption, or escheat to the state | Retail, hospitality, fitness |
| Retainage held on subcontractors | The subcontractor | On project completion and sign-off | Construction |
Notice what these have in common. None of them appear as a payable that ages. They sit quietly in the bank balance, sometimes for months, and the business behaves as though the money is spendable. It usually is spendable, right up to the filing date.
Standard Setters Are Arguing About the Same Question
The Financial Accounting Standards Board issued a proposed Accounting Standards Update on 18 August 2026 addressing whether certain digital assets qualify as cash equivalents under Topic 230, with comments due 19 November 2026. The proposal would not change the definition of a cash equivalent, but it would add illustrative examples and require enhanced disclosure of the significant components and amounts within the cash equivalents line (Journal of Accountancy, 20 August 2026).
The technical question is about stablecoins. The underlying question is the one every owner should be asking about their own balance sheet: what exactly is inside the number labelled cash, and how much of it can be used to pay a supplier next week?
The Gap Between Bank Balance and Available Cash
Consider a retail business with $180,000 in the operating account on the last day of a quarter. Sales tax collected for the quarter is $22,000, due on the 20th of the following month. Payroll tax accrued since the last deposit is $9,000. Customer deposits on undelivered special orders total $14,000. The processor holds a $6,000 rolling reserve.
The business has $180,000. It has $129,000. The 28% difference is the entire margin of error in most decisions this owner will make next month, and none of it shows up in the bank app. This is the same failure mode that makes profitable businesses run out of money, and it sits alongside the more familiar gap between cash flow and working capital.
Four Ways to Model Restricted Cash Properly
- Move it out of the operating account. The cleanest fix is mechanical. A separate account for sales tax and payroll tax, funded on the day the liability is created, removes the judgment entirely. Businesses that do this stop having tax surprises.
- If you cannot separate it, deduct it in the forecast. Add a restricted cash line that reduces the opening balance in every period. The forecast should never show a figure you are not allowed to spend.
- Schedule the release dates, not just the amounts. Sales tax due dates, deposit schedules and processor reserve release windows are all known in advance. Model them as dated outflows, the same as rent.
- Reconcile the liability accounts monthly. Sales tax payable, payroll liabilities and customer deposits should tie to a filing or a contract. If they drift, the restricted number is wrong and so is everything downstream.
The Timing Trap in September
Third quarter estimated tax payments are due 15 September in the United States, and quarterly sales tax filings for many states land in the same window. For a business on a calendar quarter, that means two significant restricted balances clearing within days of each other, often in the same period the business is building inventory for the fourth quarter. A monthly forecast averages that away. A weekly one does not, which is why forecasting at weekly granularity is the only view that catches it.
The same pattern repeats in January and April. Any business on quarterly filings has four windows a year where two or three restricted balances clear inside a fortnight, usually alongside a payroll run. Owners describe these as bad months. They are not bad months. They are predictable weeks that nobody put on a schedule, and they are one of the warning signs that a cash flow crisis is building rather than arriving.
