Tax Tip: Mixing personal and business expenses (aka commingling transactions) is one of the most common mistakes small business owners make, and it can cause big headaches later.

Why it matters:
- It muddies your financial records
- Makes tax filing harder (and riskier)
- Can jeopardize legal protections if you're an LLC or corporation

Solution:
- Open a dedicated business bank account
- Use a separate credit/debit card for business
- Record transfers clearly if you move money between accounts

Keeping things separate isn’t just neat. It protects your business, your sanity, and your bottom line.
