A client called me in a panic during tax season. Their CPA was preparing their return and asked for documentation on $8,400 in business expenses they’d claimed.
The problem? Those expenses were paid from the owner’s personal checking account and credit card—and they’d never recorded them in QuickBooks.
No record = no documentation = no deduction.
They lost $8,400 in legitimate business deductions because they didn’t know how to properly record personal payments for business expenses.
After 30+ years of bookkeeping, I can tell you this is one of the most common—and most expensive—mistakes business owners make. You grab your personal credit card for office supplies. You use your personal checking for a business lunch. You forget to record it properly.
Let me show you exactly how to record these expenses so you don’t lose thousands in deductions—and don’t create tax problems in the process.
Why This Happens (And Why It’s Costly)
Common scenarios:
- You’re at the store and realize you forgot your business card
- Your business credit card is maxed out
- You’re traveling and your personal card has better rewards
- It’s easier to just swipe your personal card for a quick purchase
The problem: If it’s not recorded in QuickBooks, it doesn’t exist for tax purposes.
Real cost: Every dollar of business expense you don’t record is 25-35 cents in taxes you shouldn’t be paying (depending on your tax bracket).
Miss $10,000 in expenses? That’s $2,500-$3,500 in unnecessary taxes.
The Wrong Way to Handle This
Mistake #1: Not Recording It At All
“I’ll just remember to tell my CPA at tax time.”
Reality: You won’t remember. And your CPA can’t deduct expenses without documentation.
Mistake #2: Recording It As Owner’s Draw
Some people record these as withdrawals from the business.
Problem: This doesn’t capture the expense, so you lose the tax deduction entirely.
Mistake #3: Recording It As Income to the Owner
This creates taxable income when you reimburse yourself.
Result: You pay taxes on money you used to pay business expenses. Double taxation.
The Right Way: Journal Entry to Owner Loan
The proper method records the expense AND tracks that you’re owed reimbursement—without creating taxable income.
Step 1: Create a Journal Entry
Click + Create, then select Journal entry.
Step 2: Enter the Transaction Date
Use the date of the actual charge. If you bought supplies on 06/30/2025, that’s your journal entry date.
Why this matters: Expenses need to be recorded in the correct period for accurate financial statements and tax reporting.
Step 3: Add a Description
Create a clear description: “Owner loan – 06/2025” or “Personal card – office supplies – 06/30/25”
Pro tip: Include enough detail so you remember what this entry was for six months from now.
Step 4: Debit the Expense Account
On the first line:
- Account: Select the appropriate expense category (Office Expenses, Travel, Meals, etc.)
- Debit: Enter the amount ($49.95 in our example)
- Description: “Paper from Office Depot” (or whatever the purchase was)
This step records the business expense, making it deductible.
Step 5: Credit the Owner Loan Account
On the second line:
- Account: “Loan to Owner” (or “Due to Owner” or “Owner Advances”)
- Credit: Enter the same amount ($49.95)
- Description: Same as above for consistency
This step tracks that the business owes you money.
Step 6: Attach Documentation
Click Attach and upload:
- Receipt photo
- Credit card statement showing the charge
- Any other documentation
Critical: The IRS requires documentation for all business expenses. Attach it now while you have it, not six months later when you’re preparing taxes.
Step 7: Save the Journal Entry
Click Save and close.
Why “Loan to Owner” Is Critical
The “Loan to Owner” account is key to avoiding tax problems.
How it works:
When you pay a business expense personally, you’re essentially loaning money to the business. The business now owes you that amount.
When you reimburse yourself later, you’re repaying the loan—which is not taxable income.
Tax implications:
- ✓ Loan repayment = not taxable
- ✗ Owner’s draw = potentially taxable depending on entity type
- ✗ Recorded as income = definitely taxable
Example:
You pay $5,000 in business expenses with your personal card throughout the year. You record them all as “Loan to Owner.”
At year-end, you write yourself a check for $5,000 and code it against “Loan to Owner.”
Tax result: You get a $5,000 business deduction (reducing your taxable income) and pay zero taxes on the $5,000 reimbursement.
If you’d done it wrong: You might pay $1,250-$1,750 in unnecessary taxes on that $5,000.
Setting Up the Owner Loan Account
If you don’t already have a “Loan to Owner” account in your chart of accounts, create one:
- Go to Settings → Chart of Accounts
- Click New
- Account type: Other Current Liabilities
- Detail type: Other Current Liabilities
- Name: “Loan to Owner” or “Due to Owner”
- Save
This account appears on your balance sheet, showing how much the business owes you at any time.
Best Practices for Managing Personal Business Expenses
1. Record Immediately
Don’t wait until month-end or tax time. Record the journal entry the same day you make the purchase.
Why: The longer you wait, the more likely you’ll forget or lose receipts.
2. Take Photos of Receipts Immediately
Use your phone to photograph receipts before they fade. Thermal paper receipts can become completely blank within weeks.
3. Create a Monthly Reimbursement Schedule
Once a month, write yourself a check for the total “Loan to Owner” balance.
Process:
- Review “Loan to Owner” account balance
- Write check to yourself for that amount
- Code the check to “Loan to Owner” (reducing the balance to zero)
This keeps personal and business funds appropriately separated.
4. Use Consistent Descriptions
Develop a naming convention: “Owner loan – [description] – [date]”
This makes it easy to identify these entries when reviewing reports.
5. Separate by Tax Year
If you’re paying personal expenses near year-end, be especially careful about dates. An expense in December should be recorded in December, not January.
Common Questions
Q: Can I just reimburse myself whenever I want?
Yes. The “Loan to Owner” account tracks how much you’re owed. Reimburse yourself whenever cash flow allows.
Q: What if I never reimburse myself?
The expense is still deductible. The “Loan to Owner” balance just grows. Eventually you can reimburse yourself, offset it against owner’s draws, or forgive the loan.
Q: Do I need my CPA’s approval for this method?
Your CPA will likely approve—this is standard accounting practice. But mention it during your year-end tax planning so they’re aware.
Q: What about business expenses on personal credit cards that earn rewards?
Many owners do this strategically. Just make sure you’re recording the expenses properly and reimbursing yourself regularly.
The Cost of Not Doing This
Real example:
Business owner pays $15,000 in legitimate business expenses throughout the year using personal funds. They never record them in QuickBooks because “it’s too complicated.”
Tax impact:
- Lost deductions: $15,000
- Additional taxes (at 30% rate): $4,500
They paid $4,500 more in taxes than necessary because they didn’t spend 10 minutes per month recording journal entries.
The Bottom Line
Personal payment of business expenses is normal. Not recording them properly is expensive.
The process takes 2 minutes per transaction:
- Create journal entry
- Debit the expense account
- Credit “Loan to Owner”
- Attach receipt
- Save
The payoff: You keep every dollar of legitimate business deductions and avoid creating taxable income when you reimburse yourself.
Action step: Right now, think about business expenses you’ve paid personally in the last 30 days. Go record them using this method before you forget.
Your tax return (and your bank account) will thank you.
