Your Bookkeeper Is Categorizing These 7 Expenses Wrong — And Costing You Real Money
I review a lot of P&Ls. Across our client base at Shahbaz & Associates — mostly business owners doing between $1M and $10M in revenue — I’d estimate that nine out of ten incoming P&Ls have at least three of the categorization errors below.
These are not obscure technical mistakes. They’re basic bookkeeping issues. And each one either inflates your tax bill, distorts your financials, or creates problems if you ever get audited.
If you’re paying a bookkeeper $40 an hour to manage this, you should at least know what “good” looks like.
1. Meals Coded As Entertainment (or Mixed Together)
After the 2017 Tax Cuts and Jobs Act, entertainment is no longer deductible. At all.
Client dinners are still generally 50% deductible as business meals, but entertainment expenses like golf, sporting events, or shows are not deductible.
The problem in practice is sloppy categorization. Most books fall into one of two traps:
- Everything gets lumped into “Meals & Entertainment,” which becomes an audit problem because the IRS can’t distinguish what’s deductible
- Or entertainment gets disguised as meals, which creates exposure if examined
The correct structure is more precise:
- Meals (50% deductible business meals)
- Meals 100% deductible (employee meals, office snacks, company events)
- Entertainment (non-deductible but still tracked for visibility)
If your bookkeeping system doesn’t separate these, your CPA ends up doing cleanup work at year-end that should have been handled monthly.
2. Owner Draws Coded Incorrectly
This is one of the most common and expensive classification errors, and it varies depending on entity type.
In an S-corporation, every dollar you take out is either wages (subject to payroll tax) or a distribution (not subject to payroll tax, but limited by basis). They are not interchangeable. If personal expenses are dumped into “distributions,” your payroll records and tax reporting start drifting apart immediately.
In a partnership or LLC taxed as a partnership, owner draws are not expenses. They are equity movements through capital accounts or guaranteed payments, depending on structure.
In a sole proprietorship, owner draws are not deductible at all and should never appear on the P&L.
A major red flag is seeing “Owner Expense” sitting inside operating expenses. That’s not bookkeeping. That’s confusion.
3. Repairs vs. Capital Improvements
This is where the tax impact can swing both directions, and mistakes are costly either way.
Repairs keep property operational: fixing a leak, replacing a broken component, servicing equipment. These are generally deductible immediately.
Capital improvements extend useful life, increase value, or adapt property for a new use: full roof replacement, HVAC upgrades, tenant buildouts, structural work. These must be capitalized and depreciated.
The distinction matters even more in 2026.
With 100% bonus depreciation permanently restored for qualifying property placed in service after January 19, 2025, properly classified capital improvements — especially Qualified Improvement Property (QIP) — can often be fully deducted in year one.
That creates a counterintuitive outcome:
Misclassifying a capital improvement as a repair may seem harmless
But it can actually increase audit risk while potentially losing structured bonus depreciation treatment
The IRS also provides relief mechanisms that are often overlooked:
- De minimis safe harbor (generally allows expensing items under $2,500 per invoice with a written policy)
- Routine maintenance safe harbor (recurring maintenance expected over the asset’s life can be expensed)
If your bookkeeper isn’t applying these deliberately, they’re guessing.
4. Loan Payments Expensed In Full
A loan payment is not a single expense. It has two components:
- Principal repayment (balance sheet movement, not deductible)
- Interest expense (deductible, subject to Section 163(j) limitations)
Yet I still regularly see full loan payments coded as “Loan Expense” or “Equipment Expense.”
The result is distorted profit, incorrect financial reporting, and reconciliation issues at tax time.
Proper accounting requires amortization schedules so each payment is split correctly between principal and interest.
If this isn’t happening, your financial statements are not reliable.
5. Sales Tax Recorded As Revenue
Sales tax collected from customers is not revenue. It’s a liability owed to the state.
It should be recorded as Sales Tax Payable on the balance sheet and removed when remitted.
When bookkeepers run it through revenue:
- Revenue is artificially inflated
- You may inadvertently cross reporting thresholds or tax regime limits
- Sales tax liabilities become unclear and underpaid over time
This is one of those errors that compounds silently until it becomes a compliance issue.
6. Credit Card Rewards Booked As Income
Business credit card rewards and cashback are generally treated as purchase rebates, not taxable income.
They should reduce the related expense category or be recorded as a contra-expense, not “Other Income.”
When booked incorrectly, they inflate revenue and distort profit metrics. Individually small, but across high-spend businesses, it adds up quickly.
7. Personal Expenses Run Through The Business
Every business owner does this occasionally. The problem is not the occasional mistake. It’s the pattern.
Once personal expenses start appearing regularly in business books, auditors tend to assume broader noncompliance and expand their sampling.
What might begin as a minor sales tax review can escalate into a full income tax examination if inconsistent personal expenses are identified.
A competent bookkeeper either:
- Flags and questions these items
- Or reclassifies them appropriately (often to owner draws)
A passive “book it and move on” approach creates unnecessary risk.
What Properly Cleaned Books Actually Look Like
When bookkeeping is done correctly, three things happen:
- Your P&L becomes a reliable tool for decision-making, not just tax compliance.
- Your tax return becomes faster, cheaper, and more defensible.
- And if you are ever audited, your CPA can support the return without reconstructing months of missing logic.
Conclusion
If you suspect your books are not quite right, but don’t want to escalate things internally, send over your last three months of P&L and balance sheet.
I’ll review it and tell you what I would fix. No pitch, no obligation.
The easiest time to correct these issues is before year-end, while there’s still time to properly classify expenses and capture any missed depreciation opportunities.
