Business expenses generally must be “ordinary and necessary” to qualify for a tax deduction. If personal purchases are recorded as business expenses, you could overstate deductions. On the other hand, if legitimate business expenses are paid with personal funds but never recorded, you could miss valuable deductions.
Mixing business and personal transactions also can distort your financial statements, making it harder to measure profitability, manage cash flow and make informed business decisions. For corporations and limited liability companies, maintaining separate finances helps reinforce the legal distinction between the business and its owners.
