This one's for the contractor, installer, or independent operator still running everything through a personal checking account. Job payments go in. Supply runs come out. At tax time, you're staring at a year of mixed transactions trying to remember what was what.
There's a better way. It starts with one move: a dedicated business bank account.
Key takeaways
- Mixing personal and business money can weaken your LLC's liability protection and cost you deductions.
- Open three things: business checking, business savings (for taxes and slow seasons), and later a business credit card.
- Bring your EIN, formation documents, operating agreement, and ID.
- FDIC insurance covers up to $250,000 per depositor, per insured bank, per ownership category. Fintech apps usually hold your money at partner banks, so read the fine print.
- Move a set percentage to savings the same day every payment lands.
Why separating your money isn't optional
It protects your LLC
The point of an LLC is that the business is separate from you. If you run personal groceries and job payments through the same account, you blur that line. In a lawsuit, the other side can argue the LLC was never really separate. Courts call it "piercing the veil." Clean accounts are one of your best defenses.
It makes taxes easier and cheaper
Every business expense buried in personal transactions is a deduction you might miss. A business account gives you, your bookkeeper, and your CPA a clean record.
It helps you get financing
When you want a work truck, equipment, or a line of credit, lenders want to see clear business income and expenses. Organized books make you look like the business you are.
What accounts you actually need
1. Business checking
Your operating account. All income goes in. All business expenses come out.
What to compare:
- Monthly fees and how to waive them
- ACH and wire fees
- Mobile deposit and how fast funds become available
- Integration with your bookkeeping software
- Cash deposit options, if customers pay you in cash
Options include big national banks, local banks, credit unions, and online business accounts. Credit unions are insured by the NCUA instead of the FDIC. Many online "business banking" apps are technology companies, not banks. They hold your deposits at partner banks. That can still be FDIC-insured, but check which bank holds your money and how coverage works before you deposit.
2. Business savings
Open it at the same place as your checking so transfers are instant. This account holds your tax money and your cushion for slow seasons, breakdowns, and surprise bills.
3. A business credit card (once you're established)
A dedicated business card keeps expenses separate and can help build business credit. Most small-business cards still require a personal guarantee, so you're on the hook if the business can't pay. Pay it off monthly. It's a tool, not a loan.
What to bring to open the account
Requirements vary by bank. Call ahead or check online. Most will ask for:
- EIN (Employer Identification Number). Get it free at IRS.gov. Never pay a third-party website for it. A single-member LLC with no employees may not technically need one for federal taxes, but most banks will ask for it, and it keeps your Social Security number off customer paperwork.
- Formation documents. Your Articles of Organization. If you're a sole proprietor using a trade name, bring your trade name registration.
- Operating Agreement (for an LLC). Some banks require it, especially with multiple owners.
- Government-issued ID for every owner on the account.
- Opening deposit. Amounts vary by bank and account.
FDIC insurance in plain English
The FDIC insures deposits up to $250,000 per depositor, per FDIC-insured bank, for each account ownership category. LLC and corporation accounts are insured separately from your personal accounts.
One catch for sole proprietors: the FDIC treats sole proprietorship accounts as the owner's personal single accounts. That means your business and personal money at the same bank share one $250,000 limit. Most tradespeople won't hit that, but it's worth knowing.
A simple money system that works
Set this up once. After a few weeks it runs on autopilot.
- Every payment goes into business checking. Even cash and payment-app transfers.
- Same day, move your tax percentage to savings. Many advisors start self-employed clients at 25–30% of each deposit for taxes, then adjust after the first year. Your CPA can give you a number based on your real income.
- Move a little more to an operating reserve. Build toward a cushion that covers a slow month.
- Pay business expenses only from business accounts. No personal card for business. No business card for personal.
- Pay yourself on a schedule. Transfer a set "owner's pay" to your personal account weekly or every two weeks. It feels like a paycheck and keeps the line clean.
- Pay estimated taxes from savings four times a year. See our guide to quarterly estimated taxes for tradespeople.
A note on payment apps
If customers pay you through Venmo, PayPal, Square, or similar apps, use a business profile and connect it to your business checking. Under current federal law, payment apps generally send a Form 1099-K when you pass $20,000 and 200 transactions in a year. All of that income is taxable whether or not you get a form.
Don't forget retirement
When you leave a W-2 job, you leave the company 401(k) behind. Self-employed people can open accounts like a SEP IRA or a Solo 401(k). Each has different rules and limits. Ask your CPA or financial professional which fits.
FAQ
Can I use my personal account if I'm a sole proprietor?
Legally you can, but you shouldn't. A separate account makes taxes, bookkeeping, and borrowing much easier.
Bank or credit union?
Either can work. Compare fees, deposit options, software integration, and whether they understand small business lending.
How much should I keep in savings for taxes?
A common starting point is 25–30% of each deposit, adjusted once your CPA sees a full year of numbers.
Do I need an EIN to open a business account?
Most banks ask for one for an LLC. It's free and takes minutes at IRS.gov.
