Separating business money from personal money is the single change that makes freelance bookkeeping manageable. It is also the one most people skip for the first year and regret at tax time.
Do you actually need one?
Sole proprietor: not legally required. You can run everything through a personal account. But at tax time you will be going through a year of mixed transactions separating a client payment from a grocery shop, and that is where most self-employed bookkeeping hours disappear.
LLC: effectively required. The liability protection of an LLC depends on treating it as separate from you. Running business income through a personal account is the textbook example of what lets a court disregard that separation. A separate account is the cheapest part of keeping it intact.
What the fees actually look like
| Account type | Monthly fee | Typical conditions |
|---|---|---|
| Online-only business checking | $0 | Usually no minimum balance |
| Traditional bank, fee-waived | $0 | Waived at a $1,500–$5,000 balance |
| Traditional bank, standard | $10 – $25 | No minimum required |
| Business account with bookkeeping built in | $15 – $30 | Includes invoicing or tax tools |
A solo freelancer has little reason to pay a monthly fee. Fee-free online business checking is widely available, and the trade-off — no branch, no cash deposits — rarely matters for someone paid by transfer.
Watch instead for the charges that are easy to miss: incoming wire fees ($10–$20 each, which matters if overseas clients pay you by wire), cash deposit limits, and transaction caps on cheaper accounts.
The feature worth choosing on
Not the interest rate. On a balance that gets spent every month, the rate is noise.
What actually changes your year is automatic sub-accounts or envelopes — the ability to route a fixed percentage of every incoming payment straight into a pot you do not touch. Set it at 25–30% and your quarterly estimated tax payments stop being a shock, because the money was never in your spending balance.
Freelancers who fail at tax time almost never fail because they did not know the rule. They fail because the money was spent before the bill arrived. Automating the split fixes that in a way discipline does not.
After that, in order of usefulness: integration with your accounting software, free incoming transfers, and fast payout on card payments if you invoice clients that way.
What you need to open one
Sole proprietor: photo ID, Social Security number, and usually a DBA (“doing business as”) registration if you trade under a name that is not your own.
LLC: photo ID, the EIN from the IRS (free, issued online in minutes — never pay a service for this), your articles of organisation, and the operating agreement if you have one.
The EIN is worth getting even as a sole proprietor. It lets you put an EIN rather than your Social Security number on every W-9 you hand a client, which is a meaningful reduction in how many businesses are holding your SSN.
A sensible setup
- One business checking account, fee-free, for all client income and business spending
- A sub-account or second account holding the tax percentage, funded automatically
- A regular transfer to your personal account — your “pay” — on a fixed date
- Optionally, a business credit card used only for business expenses, cleared monthly
That fourth item is optional and only worth it if you clear the balance every month. The point is the clean expense record, not the credit.
The bottom line
Get a separate account, pay nothing for it, and pick it on whether it can automatically hold back your tax money. A sole proprietor can skip it legally but shouldn’t; an LLC owner who skips it is undermining the protection they formed the LLC for.
