Side Business

Open a Separate Account for Your Side Business

By Camille Laurent / November 11, 2026

Your side business does not need a fancy bank. It needs its own account. The IRS tells business owners to open a business checking account early, keep it apart from the personal one, deposit receipts into it and reconcile it monthly. A sole proprietor can typically use a Social Security number to open one, and large banks list monthly fees around $15, with waivers tied to a balance. It is the cheapest bookkeeping upgrade you will make this year.

Key takeaways

The IRS says to open a business checking account early, keep it separate from your personal one, and make business payments from it.
The IRS lets you choose your bookkeeping system, but you must be able to prove your income and deductions, and a tangled account makes that harder.
Sole proprietors generally do not need an EIN, but may use one; a bank will ask for an EIN or SSN and any formation or name paperwork.
The three large-bank examples checked in November 2026 list about $15 a month, with waivers tied to balances; compare cash-deposit and transaction limits too.
A separate account is not liability protection for a sole proprietor. An LLC changes that, but state filing and a new EIN come with it.

Why the IRS cares who paid for what

The IRS does not require a particular bookkeeping system. Its recordkeeping page says you may use any system suited to your business that clearly shows your income and expenses. What you cannot skip is proof: you must be able to substantiate the entries and deductions on your return. Publication 583 gives retention specifics: generally 3 years from filing, 6 years if you omitted more than 25 percent of the gross income shown on a return, and at least 4 years for employment tax records.

Publication 583 is blunter about the bank account than about almost anything else. It says one of the first things to do when you start a business is open a business checking account, keep it separate from your personal account, deposit all daily receipts in it and make payments by check so each expense is documented. It adds that you should reconcile the account every month.

Business versus personal expenses

A business expense must be ordinary and necessary, and personal expenses are not deductible. Where something is used for both, you split it. Publication 583’s example is a flower shop van driven 20,000 miles, 16,000 for business, so only 80 percent of the operating cost counts. If you pay a personal expense from the business account, it must still be recorded, but it cannot be deducted. A separate account makes that split visible. Without one, you sort a year of groceries from supplies in March.

What you can and cannot do with a personal account

The IRS pages I read do not forbid a sole proprietor from using a personal account. The concern is adequate records, not which account holds the money. The practical problems:

Proof. If business and personal transactions share a statement, every line becomes a question you have to answer later.
The bank’s own terms. Your account agreement may limit business use. I did not check any specific bank, so read yours.
The name on the check. A personal account has your name on it, not your business name, which can matter to customers.
Insurance. The FDIC treats a sole proprietorship’s account as the owner’s single account, combined with the owner’s other single accounts at the same bank, and insured up to $250,000 in total. A separate business account does not buy you a second $250,000 at the same bank.

The Small Business Administration adds a point that matters: a sole proprietorship has no separate legal existence, so the owner can be personally liable for business debts. A separate account is a bookkeeping tool, not a shield. The SBA describes a business account as offering limited personal liability protection, but its sole proprietor warning still applies.

What a business account needs

Requirements vary by bank. The SBA lists what is commonly requested: an EIN (or your Social Security number if you are a sole proprietor), business formation documents, ownership agreements and a business license, and notes that some banks ask for more.

EIN or SSN

The IRS Form SS-4 instructions say a sole proprietor generally needs just one EIN no matter how many businesses or trade names they use, and that an EIN is for business activities only. They do not say every sole proprietor must have one. You typically need an EIN if you hire employees or file certain excise, employment or similar returns, or have a qualified retirement plan. The instructions say an online applicant receives the EIN immediately.

Business name and DBA paperwork

The SBA says that if you operate under your own legal name, you typically do not need to register anywhere. A trade name, or “doing business as,” may need to be registered with the state, county or city. If you plan to deposit checks made out to a business name instead of yours, expect the bank to ask for proof you may use it. Rules differ by state and locality, so check yours.

Fees and minimums to compare (November 2026)

Bank fees change, so these are snapshots from the banks’ own pages in November 2026, listed as examples of what to compare and not as recommendations.

Bank and account	Monthly fee	Waiver or minimum	Limits worth noting
Chase Business Complete Banking	$15	Waiver criteria not shown on the page; an “avoid fee” link is provided	Up to 20 paper and teller transactions; $5,000 in-branch cash deposits included
Capital One Basic Checking	$15	Waived if the prior 30- or 90-day balance averages $2,000 or more	Unlimited digital transactions; teller cash deposits above $5,000 a month cost $1 per $1,000
Wells Fargo Initiate Business Checking	$15 or $0	$25 minimum opening deposit; waiver terms are in a separate document	Mobile deposit limits apply; amounts not stated on the page

The fees look alike, the waiver rules do not, and cash-heavy sellers should read deposit limits first, since a $1-per-$1,000 teller fee adds up. The SBA also suggests comparing introductory offers, transaction fees, early termination fees and minimum balance fees.

Where payment processor payouts land

If you sell through a card processor or payment app, payouts must land somewhere. Stripe’s payout documentation, as an example, says you can link checking and savings accounts, and that payouts scheduled for a weekend or holiday arrive the next business day. It describes US settlement as roughly two business days after the initial period, and says manual payouts typically take one to four business days. Check your own provider’s page for timing.

Point payouts at the business account and the money trail stays in one place. Under rules the IRS describes for 2026, a payment platform generally must file a Form 1099-K only if your payments exceed $20,000 and you have more than 200 transactions. But a platform may send one below that, and the IRS Taxpayer Advocate Service notes that income must be reported whether or not you receive a form. Personal payments between friends and family, and gifts, are not taxable, and the service suggests labeling them clearly.

Bookkeeping habits that actually stick

Personal versus business account

Question	Personal account used for the side business	Separate business account
Proof of income and expenses	Sorted line by line later	Statement is a clean record
Name on checks	Your personal name	Business or DBA name, if registered
ID needed to open	Already have it	EIN or SSN, plus any name or formation paperwork
Monthly fee	Varies by bank	Often about $15 at large banks, waivable
Deposit insurance	Insured as your single account	Also insured as your single account, combined with the rest
Liability protection	None	None, for a sole proprietor

Habits matter more than software. Pay business costs only from the business account, and take money out only as a withdrawal for personal use, which Publication 583 says to do by writing a check to yourself; a personal withdrawal is not a business expense. Keep a receipt or written note for every cash payment, and reconcile monthly on a fixed date. If you pay a personal bill from the business account by mistake, record it instead of burying it.

When an LLC changes the picture

An LLC is a legal structure formed under state law, usually by filing articles of organization with the state, often through the Secretary of State, and naming a registered agent. The SBA says LLC members are generally shielded from personal liability for business debts “in most instances,” while a sole proprietor is not. Under IRS rules, a domestic LLC with one member is disregarded as separate from its owner by default, so income and expenses still go on your own return, such as Schedule C, and the instructions say to write “disregarded entity” on the EIN application. The Form SS-4 instructions note an LLC can elect corporate status, which changes the tax picture.

For the bank account, the change is that the account opens in the LLC’s name, and a bank will typically want your formation documents and EIN. Keeping funds apart matters even more, since the SBA ties the account’s limited protection to separating business and personal money. Whether an LLC is worth its state fees and paperwork depends on your state and risk.

Setup checklist

Decide the name you will operate under; check whether your state, county or city requires registering a trade name.
Decide whether to get a free EIN from the IRS website or use your SSN as a sole proprietor.
Gather ID, EIN or SSN and any name or formation papers the bank lists.
Compare monthly fee, waiver rules, cash-deposit and transaction limits across two or three banks.
Open the account and point payment processor payouts and customer payments to it.
Set a monthly date to reconcile and file receipts.

Frequently asked questions

Do I need a separate account if I make only a little money?

The IRS pages I read set no income minimum for this advice. They say to open a business checking account early and keep it separate, and that you must be able to prove your income and deductions. Small side income still has to be reported.

Do I need an EIN to open one?

Not necessarily. The SBA says a sole proprietor can use a Social Security number. Banks differ, so ask first. You may need an EIN if you hire employees or file certain tax returns.

Will a separate account protect my personal assets?

Not by itself. The SBA says a sole proprietorship is not a separate legal entity, so you can be personally liable for business debts. An LLC changes this in most instances.

Can I pay myself out of the business account?

Yes, as a withdrawal for personal use, which Publication 583 says to do by writing a check to yourself. A personal withdrawal is not a business expense, so record it as one.

Before you decide

Open the account before you need it. Pick it by waiver rules and cash limits, not the sign-up bonus. If you are weighing an LLC, ask an accountant or attorney in your state.
