Do You Use a Personal Credit Card for Business Expenses? Read This Tax Court Case First.
Many small business owners regularly pay company expenses with personal credit cards. Others personally borrow money when the business cannot obtain financing. Most assume that if the money was used for business purposes, the related interest expense is automatically deductible by the business.
A recent Tax Court case demonstrates why that assumption can be costly.

United States Tax Court DAWSON System
The Court's decision provides an important lesson for business owners, particularly those operating LLCs and S corporations.
What Happened In Simmons?
The taxpayers operated a specialty retail store through an LLC taxed as a partnership. Because the business had difficulty obtaining credit, the owners frequently opened credit cards in their personal names and used those cards to pay business expenses.
The business also received funding from loans obtained personally by the owners. Interest associated with those loans and credit card balances was recorded in the company's accounting records and deducted on the partnership tax return.
During an IRS examination, the agency challenged numerous deductions, including the claimed interest expense.
The taxpayers argued that the debt was incurred to support business operations and that the related interest should therefore be deductible.
The Tax Court disagreed.
The Real Issue Was Ownership Of The Debt
Under Internal Revenue Code Section 163, interest is generally deductible only by the taxpayer that is legally obligated to pay the debt.
The Court found that the credit cards were opened in the owners' individual names rather than in the name of the LLC. While the business may have made payments on the balances, the taxpayers failed to establish that the LLC itself was legally liable for the debt.
This distinction proved critical.
Many business owners assume that using borrowed funds for business purposes automatically creates a business deduction. In reality, the legal structure of the borrowing arrangement often matters just as much as how the funds are used.
QuickBooks Was Not Enough
The taxpayers maintained accounting records and recorded interest expense in QuickBooks. Unfortunately, bookkeeping entries alone were not sufficient to satisfy the Court.
The Tax Court repeatedly focused on the lack of supporting documentation.
The taxpayers could not adequately demonstrate:
- That the debt legally belonged to the business
- That all underlying charges were business related
- That personal expenses were never commingled with business expenses
- How the interest expense was calculated and allocated
- That the accounting records matched the underlying source documents
The Court noted inconsistencies between certain accounting records and credit card statements and ultimately concluded that the taxpayers failed to meet their burden of proof.
Why This Matters For LLC And S Corporation Owners
The facts in Simmons are common.
Many small business owners:
- Pay business expenses with personal credit cards
- Use personal funds to cover cash flow shortages
- Personally guarantee business obligations
- Transfer money between personal and business accounts without documentation
- Record transactions after the fact based solely on bank activity
These practices often work without issue until an IRS examination occurs.
Once an auditor requests supporting documentation, weaknesses in the recordkeeping process become apparent.
Better Planning Alternatives
Business owners can significantly strengthen their position by implementing proper procedures before problems arise.
Consider the following best practices:
- Use dedicated business credit cards whenever possible
- Maintain separate business and personal bank accounts
- Document owner loans with written promissory notes
- Maintain detailed reimbursement records
- Implement an accountable plan when appropriate
- Retain receipts and supporting documentation
- Reconcile accounting records monthly
- Document the business purpose of significant expenditures
These steps not only improve bookkeeping accuracy but also provide stronger support if deductions are later challenged.
The Hidden Audit Risk
One of the most important aspects of the Simmons case is that the taxpayers lost despite operating what appeared to be a legitimate business.
The Court did not conclude that the business was fictitious or that the owners intentionally violated the tax law. Instead, the taxpayers failed to adequately document their position and prove entitlement to the deduction.
That distinction matters because many IRS disputes arise from insufficient documentation rather than improper tax planning.

Final Thoughts
The Simmons case is not really a credit card interest case. It is a documentation case.
The taxpayers deducted nearly $17,000 of interest expense but could not prove that the debt belonged to the business or adequately substantiate the underlying transactions. As a result, the deduction was denied.
For business owners, the lesson is clear. Proper documentation, separate accounts, and well structured reimbursement procedures are often just as important as the deduction itself.
