> Why a 1099-K vs bank deposits never match: gross amounts, fees, refunds and timing, and a worksheet that explains the gap to the client's preparer.
A 1099-K and the client's bank deposits rarely match because the form reports gross payments before the processor takes fees, refunds and chargebacks, while the bank only sees the net payouts. Timing adds more gap at year end, and other deposits never touch the processor. A short worksheet walks from the 1099-K total to the deposits in the books.

## Why does a 1099-K total never match the bank deposits?

A 1099-K total and the bank deposits measure different things. The form counts what customers paid through a card processor or payment platform during the calendar year. The bank statement counts what the processor actually sent to the client's account, after its deductions, on the dates the money landed.

Four kinds of difference account for almost every gap:

1. **Fees.** The processor keeps its fee before paying out.
2. **Refunds and chargebacks.** Money returned to customers comes out of later payouts.
3. **Timing.** Sales on the last days of December often pay out in January.
4. **Other deposits.** Checks, ACH payments from customers, transfers and loans reach the bank without passing through the processor.

The first three make the bank deposits from the processor smaller than the form. The fourth makes total bank deposits larger. A client with a lot of check income can see total deposits above the 1099-K even though the processor deposits alone are below it, and the two effects can partly cancel and hide each other.

That is why comparing one total against another proves little. The useful comparison is the 1099-K against the processor's own payouts, with the other deposits listed separately.

## Gross 1099-K amounts and the fees taken before deposit

The amount on a 1099-K is gross. The [IRS instructions for Form 1099-K](https://www.irs.gov/instructions/i1099k) say the gross amount is reported without regard to any adjustments for credits, cash equivalents, discount amounts, fees or refunded amounts. Every dollar a customer paid counts, even the part the processor kept.

Fees are the most predictable part of the gap. A processor that charges a percentage plus a fixed amount per transaction produces fees that move with sales, so a client with steady volume sees a steady fee share each month. The processor's monthly or annual statement normally shows total fees, and that figure belongs on the worksheet.

The books should show the fees too. If the bookkeeper records only the net payout as sales, revenue is understated by the fees and the fee expense is missing. Recording the gross sale, with the fee as a separate expense, keeps the books in step with the form and makes the year-end comparison much shorter.

Gross can also include amounts the client never keeps as income. Customers pay the full ticket, so sales tax collected and tips passed to staff can sit inside the processor's total. Those need their own line on the worksheet so they are not mistaken for unreported sales or missing deposits.

## Refunds, chargebacks and timing gaps between a 1099-K and deposits

Refunds and chargebacks reduce what the processor pays out but not what the 1099-K reports, because the form ignores refunded amounts. Timing differences come from the gap between a sale and its payout, which pushes some December sales into January deposits. All three should be listed separately on the worksheet, with their own totals.

### Refunds

A refund issued through the processor is usually netted against the next payout. On the bank statement it is invisible: the deposit is simply smaller. The processor's report shows each refund, and the year's total is a line on the worksheet.

### Chargebacks

A chargeback is a customer dispute the processor reverses, often with an added fee. It behaves like a refund on the payouts, and the dispute fee adds to the fee line. If the client later wins the dispute, the money comes back in a later payout, which can cross a year boundary.

### Timing at both ends of the year

Payouts often land one or more business days after the sale. Sales on December 30 and 31 are on this year's 1099-K but arrive in the bank in January. The same thing happened a year earlier, so the first January deposits on this year's statements include last December's sales. The worksheet subtracts the first and adds the second.

Look at the processor's payout report for the first and last week of the year to size these amounts. The bank statement alone cannot tell you which sale a payout belongs to.

## Bank deposits a 1099-K never sees

Many bank deposits have nothing to do with the processor, and the 1099-K never sees them. Customer checks, ACH and wire payments, transfers from the owner's personal account, loan proceeds, tax refunds and interest all arrive in the bank directly. Some are income and some are not, so each needs its own category in the books.

Sort these deposits into two groups:

- **Income outside the processor**: customer checks, ACH and wires, cash deposits and interest. These are taxable sales or income that no 1099-K will report.
- **Money that is not income**: owner contributions, loan proceeds, transfers between the client's own accounts, refunds of deposits and similar items.

The second group is where mistakes hide. An owner who moves money in from savings, or who deposits a personal retirement account distribution into the business account to cover a slow month, creates a deposit that looks like a sale. Code it to equity, not revenue. Owner retirement money moving through the books comes up in [recording retirement contributions in client books](/blog/retirement-contributions-in-client-books), including which side of the books it belongs on.

Payroll deposits also deserve a look. A refund of overpaid payroll tax, for example, lands in the bank but is not a sale. The year-end payroll forms are worth gathering in the same pass, and the [year-end payroll forms checklist](/blog/year-end-payroll-forms-checklist) lists what to collect.

## A 1099-K to bank deposits reconciliation worksheet

A reconciliation worksheet starts at the gross 1099-K total and adjusts it, line by line, until it reaches the processor deposits in the bank for the year. Then it adds the other deposits to reach total deposits. Each line names its source, so the preparer can check any number against a report.

The worksheet below is an example for a made-up retail client with one processor and one checking account. All figures are illustrative.

| Line | Amount | Source |
| --- | --- | --- |
| Gross payments per 1099-K | 128,400.00 | Form 1099-K, box 1a |
| Less refunds | (3,150.00) | Processor annual report |
| Less chargebacks | (620.00) | Processor annual report |
| Less processor fees, including dispute fees | (3,880.00) | Processor annual report |
| Net payouts for sales in the year | 120,750.00 | Subtotal |
| Less this December's sales paid out in January | (1,450.00) | Payout report, last week of year |
| Plus last December's sales paid out this January | 1,210.00 | Payout report, first week of year |
| Processor deposits in the bank this year | 120,510.00 | Bank statements, processor lines |
| Plus customer checks and ACH | 22,300.00 | Bank statements, categorized |
| Plus owner contribution (not income) | 5,000.00 | Bank statements, equity |
| Total deposits per bank statements | 147,810.00 | Twelve statements |

Read it from the top. The processor deposits of 120,510.00 are 7,890.00 below the form, and every dollar of that is explained by refunds, chargebacks, fees and timing. Total deposits are 19,410.00 above the form, explained by check and ACH income and one owner contribution.

If the client collects sales tax at the register, add a line for it between gross payments and net payouts, so the preparer sees that part of the gross belongs to the state.

When the bottom line of the worksheet does not equal the total deposits in the books, the remainder is unexplained. Show it as its own line rather than folding it into another one.

## When should a 1099-K gap worry the bookkeeper?

A 1099-K gap should worry the bookkeeper when it cannot be explained line by line, or when it runs the wrong way. Processor deposits higher than the gross 1099-K, a gap far larger than the fees and refunds support, or a form from a platform the client never mentioned all point to a real problem.

Some signs to treat as red flags:

- **Processor deposits above the 1099-K gross.** Deposits after fees should not exceed gross sales. A second processor account, a deposit miscategorized as processor income or a wrong form is likely.
- **A 1099-K the client did not expect.** A form from a marketplace or app nobody mentioned means an account outside the statements you have. The IRS page on [understanding your Form 1099-K](https://www.irs.gov/businesses/understanding-your-form-1099-k) notes that a form may be issued even when payments fall below the reporting threshold, so a small side channel can still produce one.
- **Personal payments on a business form.** Friends repaying a dinner through the same app account can end up in the total. The client needs to document those, and the preparer decides how to handle them.
- **No form at all.** A client with real sales through a payment app or online marketplace may receive no 1099-K if the threshold is not met. The instructions set it at gross payments over $20,000 and more than 200 transactions for third party network transactions. No form does not mean no income.

Bring these to the preparer early, with what you know and what you do not.

## Sending the 1099-K worksheet to the client's preparer

The 1099-K worksheet goes to the preparer with the form itself, the processor's annual report and the year's categorized deposits. That package lets the preparer accept the gap as explained, or ask about one specific line, instead of starting from two totals that disagree.

Include, for each processor account:

1. The 1099-K, or a note that none was received.
2. The processor's annual or monthly summary showing refunds, chargebacks and fees.
3. The completed worksheet.
4. A list of any unexplained remainder, with dates and amounts.

Not every client needs this work. A consultant paid only by ACH has nothing to reconcile, while a retailer or restaurant on card sales needs it every year. Sorting clients by how they get paid helps plan the season, and [client segmentation for bookkeepers](/blog/client-segmentation-for-bookkeepers) shows ways to group a client list for that kind of planning.

The bank side of the worksheet depends on every deposit being categorized. [AutoBankConvert](/) converts the year's statements in a batch and assigns each line to an account, so processor payouts, customer checks and owner transfers are already separated when the 1099-K arrives.
