My Bookkeeper and Tax Preparer Gave Me Different Numbers — Who’s Right?
When Lauren’s tax preparer handed her a Schedule C showing $23,000 more profit than her bookkeeper’s year-end report, her first thought was that someone had made a $23,000 mistake. Neither of them had.
Key Takeaways
- A bookkeeper records what happened. A tax preparer decides what’s deductible. Two jobs, and they can land on two different numbers.
- The gap usually isn’t a mistake — it’s the cost of books that were never built to match the tax return.
- Money you pay yourself (owner’s draw) is not a deductible expense, even if it’s sitting in your books as one.
- Materials can be deducted when bought or when sold, depending on the accounting method you elect — but your books and your return have to use the same one.
- Your 1099-K reports gross sales. If your books show only the deposits that hit your bank, your revenue won’t match the IRS’s copy.
- Books built to Schedule C from the start make the surprise — and the gap — disappear.

1. Two Numbers, One Panicked Email
Lauren runs a small online home-goods shop out of her garage. Candles, ceramics, a few seasonal bundles that sell well in November. She’d done the responsible thing: hired a bookkeeper to keep her QuickBooks tidy all year, and a separate tax preparer to file the return. Two professionals. She figured that meant two layers of safety.
Then her preparer’s draft came back. Net profit on the Schedule C: $61,000. Her bookkeeper’s year-end profit-and-loss said $38,000. Same business, same year, a $23,000 difference — and the bigger number was the one she’d owe tax on.
That was the email I got. And it’s the part most people get backwards: she assumed the gap meant an error. It almost never does. The gap is information. It tells you exactly where your books and your tax return stopped speaking the same language.
2. Why Two Professionals Get Two Answers
A bookkeeper’s job is to record what moved through your accounts. Money came in, money went out, here’s the category. They work from what they can see — bank feeds, card statements, the labels you (or they) chose.
A tax preparer’s job is different. They take that record and ask a second question the bookkeeping never asked: is this actually deductible? Owner’s pay, personal charges, inventory timing, depreciation — none of that is obvious from a bank feed. It only shows up when someone applies the tax rules.
Bottom line
When books aren’t built to the tax return’s rules, the preparer has to re-sort everything at filing time — and that re-sorting is the gap you’re seeing.
So the question isn’t “who’s right.” It’s “what did the return change, and why.” Once you can name each adjustment, the mystery turns into a checklist. Here’s Lauren’s.
3. Where the $23,000 Actually Went
I rebuilt the bridge between her two numbers line by line. Every dollar of the difference came from three categorization choices — not one of them a math error.
| Item | Adjustment | Why |
|---|---|---|
| Bookkeeper’s P&L net profit | $38,000 | The starting point |
| Owner’s draws booked as “contract labor” | +$12,000 | Paying yourself isn’t a deductible expense |
| Personal charges on the business card | +$6,500 | Personal spending was never deductible |
| Materials expensed when bought, not when sold | +$4,500 | Her books didn’t match her own accounting method |
| Tax preparer’s Schedule C net profit | $61,000 | What actually gets filed |
Look at what each line really is. The $12,000 she’d been calling “contract labor” was Lauren paying herself — that money belongs in equity as a draw, not in expenses. The $6,500 was groceries, a flight, a vet bill that happened to ride on the business card.
The $4,500 was wax and jars she’d bought in December but hadn’t turned into sold candles by the 31st. Here’s the nuance most write-ups skip: a small business like Lauren’s usually isn’t forced into strict inventory accounting at all. Under current rules, a business under the gross-receipts threshold can elect to treat materials as non-incidental supplies and deduct them when used or consumed, rather than capitalizing them as inventory. The problem wasn’t that she couldn’t deduct the wax — it’s that her books expensed it on purchase while her return was being prepared on a sold-not-bought basis. The two weren’t using the same method, so the preparer had to reconcile them at the end.
Her bookkeeper hadn’t lied about any of it. The entries were faithful to what showed up in the feed. They just weren’t sorted the way a Schedule C reads them — so the preparer did the sorting at the end, all at once, and it landed as a $23,000 shock.
The method matters more than the rule: Small businesses get real flexibility in how they handle materials — deduct when bought or when sold, depending on the method elected. Neither is “wrong.” What causes the gap is picking one method on the return and keeping the books on the other. Consistency between the two is the whole game.
4. The Revenue That Didn’t Match the 1099-K
There was a second mismatch hiding underneath the profit one, and it worried me more.
Lauren’s books recorded revenue from the deposits that actually hit her checking account — net of her payment processor’s fees. That came to $142,000. But her 1099-K reported gross sales: $149,500. The $7,500 difference was the processing fees, which had never been booked as an expense at all.
Important: Booking only your net deposits doesn’t change your profit — the missing fees cancel out. But your revenue line ends up $7,500 below what the IRS already has on file. That gap is exactly the kind of thing the IRS’s matching system flags, and it can arrive months later as a CP2000 notice asking why your reported sales came in short.
So one mismatch (profit) costs money. The other (revenue) invites a letter. Both come from the same root: books that weren’t reconciled to the documents the IRS receives.
5. What If Your Situation Is a Little Different?
“I’ve been filing the bookkeeper’s number for years.”
This is the version that keeps me up. If draws and personal charges were buried in expenses on past returns, those returns may have understated your profit — which means tax that was under-reported. That’s not something to brush off because the number feels small. Whether a prior year rises to the level of needing an amended return depends on the amounts and the facts, and that’s a judgment worth making deliberately rather than assuming either way. The point isn’t to panic; it’s to look back with clear eyes before you decide, instead of discovering the pattern a third year in a row.
Practical point
A higher profit on this year’s return often points to the same pattern on last year’s. Fix the cause once, and you stop re-living the surprise every spring.
“My preparer’s number came out lower than my books.”
That happens too — usually when deductions live on the return but never made it into the bookkeeping. Mileage, the home-office calculation, depreciation on equipment. The direction of the gap doesn’t tell you who’s right. The mapping does. A lower preparer number isn’t a “win”; it just means the missing pieces were caught somewhere other than your books.
“The profit matches, but the revenue doesn’t.”
Treat these as two separate checks. You can have a perfectly correct bottom line and still have a revenue figure that won’t tie to your 1099-K. Reconcile the top line to the form first — it’s the one with a notice attached to it.
6. What to Check Right Now
- Pull your 1099-K(s) and compare the gross total to the revenue line on both your P&L and your draft Schedule C.
- Hunt for “owner’s draw,” “owner pay,” or “contract labor” lines that are really you paying yourself — those belong in equity, not expenses.
- Scan your business card statements for personal charges that slipped into the books.
- Confirm your books and your return treat materials the same way — both when bought, or both when sold, not one each.
- Confirm where mileage, home office, and depreciation live — in the books, on the return, or (the dangerous one) counted in both.
EA Insight
The mistake I see most often isn’t a wrong number. It’s two roughly-right numbers that were never built to meet. When a client sends me both, I don’t ask which one to trust — I rebuild the bridge between them, because the bridge is where the real answer lives.
My order of operations is deliberate. I reconcile revenue to the 1099-K first, because a profit error costs money but a revenue mismatch invites a letter. Then I move owner’s pay out of expenses, strip the personal charges, and line up the inventory method — in that sequence, because that’s the order the IRS reads them.
What I don’t do is blame the bookkeeper or tell anyone to fire their preparer. The bookkeeper entered what they saw; no one had told them a draw isn’t an expense. The preparer’s number was perfectly defensible. It only felt like a betrayal because the books were speaking a different language than the return — and that’s a fixable problem, not a people problem.
EA Summary
Two professionals can hand you two different numbers and both can be doing their jobs. The gap isn’t a mistake to catch — it’s a sign your books and your tax return were never speaking the same language. Build the books to the Schedule C from the start, and the gap disappears, taking the springtime surprise with it.

Frequently Asked Questions
Does a gap mean my bookkeeper did something wrong?
Usually not. A bookkeeper records what comes through your accounts; deciding what’s deductible is a separate, tax-specific job. The gap is most often the difference between those two jobs — not a sign of carelessness.
Which number do I actually file?
The one that follows the tax rules — draws out of expenses, personal charges removed, materials handled consistently with your accounting method. That’s usually closer to the preparer’s figure, but the point isn’t to pick a side. It’s to confirm every adjustment is correct so the number you file is one you can defend.
Why doesn’t my revenue match my 1099-K?
A 1099-K reports your gross sales, before any processor fees come out. If your books record only the deposits that reach your bank, your revenue will sit below the form by the amount of those fees. Book the fees as an expense and report the gross — your profit stays the same, and your revenue ties to the form.
Can one person keep my books and file my return?
Yes. An Enrolled Agent is federally authorized to practice before the IRS, so the same person can both maintain your books and prepare your return. When one set of standards runs through both, there’s no year-end re-sorting and no surprise gap to explain.
