Separate Your Money: Business Banking From Day One
Why mixing personal and business money costs you at tax time, weakens your liability protection, and makes lenders nervous, plus the simple setup that fixes it.
When you are just starting, it feels easier to run everything through one account. A client pays you, you buy groceries, you pay for supplies, and it all blends together. Then tax season or a loan application arrives, and untangling it takes days.
Mixing personal and business money is called commingling, and it is one of the most common (and fixable) mistakes new owners make.
Why commingling hurts
| Area | What goes wrong |
|---|---|
| Taxes | Hard to prove which expenses were business, so deductions get missed or questioned |
| Liability | Courts may disregard an LLC that is treated like a personal piggy bank |
| Lending | Lenders cannot see true business revenue in your statements |
| Decisions | You cannot tell whether the business actually made money |
The three-part setup
- 1
Get an EIN
An Employer Identification Number is a free federal ID for your business. Apply directly on IRS.gov (avoid sites that charge for it). Even without employees, it lets you open accounts and keep your Social Security number off client forms.
- 2
Open business checking
All business income goes in and all business costs come out. Compare monthly fees, minimum balances, deposit options, and how well it connects to your bookkeeping software.
- 3
Use a business card
A dedicated card keeps purchases separate, simplifies records, and over time can help build your business credit.
Paying yourself
Move money from business to personal with a regular, recorded transfer (an owner's draw or payroll), not by swiping the business card for personal items. See paying yourself for ways to set the amount.
