You can deposit money into your sole proprietor business account, but the bank controls who else can
As the sole proprietor, you have full authority to deposit into your business checking account. You can walk into the bank, use the ATM, make mobile deposits, or set up transfers from your personal account. The account is in your name or your business name (or both), and you own it outright.
Whether other people can deposit into that account depends entirely on how you set it up with the bank. Most banks allow you to add authorized users or signatories to a business account, but the rules vary by institution and by account type. Some banks restrict deposits to the account owner only unless you explicitly grant permission in writing.
The practical question most sole proprietors face is whether to let employees, contractors, or family members deposit customer payments, refunds, or loan proceeds directly into the business account. That decision affects your accounting, your fraud risk, and your ability to track money flow.
Key Takeaways
- You as the owner can always deposit into your sole proprietor business account through any method the bank offers.
- Other people can deposit only if the bank's account agreement allows it and you have authorized them in writing.
- Most banks allow you to name authorized users or signatories, but the specific permissions vary — some allow deposits only, others allow withdrawals too.
- Adding someone to the account creates a paper trail for the IRS and may affect your liability if that person makes unauthorized transactions.
- A safer alternative for employees or contractors is to have them deposit into a separate collection account that you control, then transfer the balance to your business account weekly.
What the bank's account agreement actually says about deposits
When you open a sole proprietor business checking account, the bank gives you an account agreement that spells out who can do what. Read the section on authorized users or signatories — this is where the bank defines deposit rights. Most agreements say the account owner can deposit at any time, but other people can deposit only if you have added them to the account in writing and the bank has approved them.
Some banks distinguish between "authorized users" (who can deposit and withdraw) and "signatories" (who can sign checks and withdraw but may not be able to deposit). Others use different terminology entirely. Chase, Bank of America, Wells Fargo, and regional banks all have different rules, so you cannot assume one bank's policy applies to another.
The key is that the bank, not you, decides what permissions each person gets. You cannot unilaterally decide that an employee can deposit but not withdraw. You can only choose from the options the bank offers, and you have to request the change in writing — usually by filling out a form at a branch or online.
How to add someone to your account so they can deposit
If you want an employee, contractor, or family member to be able to deposit into your account, contact your bank and ask for the form to add an authorized user. You will need that person's full legal name, date of birth, and Social Security number or tax ID. The bank will run a background check on them, which usually takes a few business days.
Once the bank approves them, that person can deposit via ATM, mobile app, or in person at a branch — depending on what the bank allows. They will typically receive a debit card or online access to the account. Make sure you understand what permissions they have before you hand them access. If the bank's default is to allow both deposits and withdrawals, and you only want deposits, ask the bank in writing to restrict their access to deposits only. Document this request in case there is a dispute later.
You remain liable for anything that person does on the account, even if they exceed the permissions you intended. If they withdraw money without your knowledge, the bank will look to you to resolve it, not to them. This is why many sole proprietors choose not to add employees to the account at all.
Why some sole proprietors avoid adding other people to the account
Adding an authorized user creates liability and accounting complexity. If that person makes a mistake — depositing a check twice, withdrawing money by accident, or depositing a fraudulent check — you are responsible for fixing it. The bank will not reverse the transaction just because you did not authorize it. You have to prove the person acted without your permission, which is hard to do if they are an authorized user.
From an accounting standpoint, adding someone to the account means you have to track their deposits separately from yours. If you are reconciling the account monthly, you need to know which deposits came from which person, because that affects how you categorize the income in your books. If the person deposits customer payments, refunds, or loan proceeds, you need a record of what they deposited and when, so you can match it to your invoices or loan documents.
The IRS also looks at business accounts during an audit. If multiple people are depositing into the account, the IRS may ask you to explain the source of each deposit. If you cannot, or if the deposits do not match your reported income, you may face questions about unreported income or commingling of personal and business funds.
A safer alternative: the collection account model
Many sole proprietors use a two-account system instead. They open a second business checking account (the "collection account") and give employees or contractors access to that account only. Customers, clients, or partners deposit into the collection account. Once a week or once a month, the sole proprietor transfers the balance from the collection account to the main business account.
This approach isolates the risk. If someone makes a mistake or commits fraud in the collection account, your main business account is not affected. You have a clear record of what went into the collection account and when, which makes reconciliation and tax reporting easier. The IRS sees two accounts, but the flow is clear: money comes in through the collection account, then moves to the main account.
The downside is that you pay for two accounts, which usually costs $10 to $30 per month depending on the bank. You also have to manage two sets of login credentials and reconcile two accounts. For a sole proprietor with one or two employees, this cost is usually worth the protection and clarity it provides.
What happens if someone deposits a fraudulent check into your account
If an authorized user deposits a bad check — one that bounces, is forged, or is stolen — you are responsible for the loss, not the person who deposited it. The bank will reverse the deposit and charge you a fee, usually $25 to $35. If the check was for a large amount, you may end up overdrawn.
You can sue the person who deposited the check to recover your loss, but that requires hiring a lawyer and proving they acted negligently or intentionally. Most sole proprietors cannot afford to do this, especially if the person is an employee they still need to work with. This is another reason to limit who has access to the account.
If you suspect fraud, contact your bank when ready. The bank has procedures for disputing fraudulent deposits, but you have to report it within a specific window — usually 30 to 60 days. After that, the bank will not reverse the transaction.
Deposits from your personal account to your business account
As the sole proprietor, you can transfer money from your personal checking account to your business account whenever you want. This is called a capital contribution or owner deposit. The IRS treats this differently from business income, so you need to categorize it correctly in your accounting software.
Most banks allow you to set up a standing transfer or a one-time transfer online. If you are depositing a check, you can deposit it to your business account directly — you do not have to deposit it to your personal account first. If you are moving cash, you can deposit it at a branch or through an ATM, depending on the amount and the bank's policies.
Keep records of these transfers. If you are audited, the IRS will want to know where the money came from. If you transferred it from your personal account, you should have a record showing the source of that money — a bonus, a loan, savings, or a side job. If you cannot explain where the money came from, the IRS may treat it as unreported income.
Frequently Asked Questions
Can a family member deposit into my sole proprietor business account?
Only if you add them as an authorized user and the bank approves them. You will need to fill out a form with their personal information and the bank will run a background check. Once approved, they can deposit through the methods the bank allows — usually ATM, mobile app, or in person.
What if I want someone to deposit but not withdraw?
Ask the bank in writing to restrict their access to deposits only. Not all banks offer this option, so confirm before you add the person. If the bank does not offer deposit-only access, you will have to choose between giving them full access or not adding them at all.
Do I have to report deposits from other people to the IRS?
It depends on the source. If someone deposits customer payments or business income on your behalf, that is business income and you report it as such. If someone deposits a personal loan or a gift, you do not report it as income, but you should categorize it correctly in your accounting so the IRS does not think it is unreported business income.
What if an employee deposits money and then quits?
Contact your bank and remove them as an authorized user when ready. The bank will revoke their access to the account, usually within one business day. If they have a debit card, it will stop working. If they have online access, their login will be disabled. Make sure you change any passwords or security questions they may have seen.
Can I deposit checks made out to my business name into a personal account?
Technically yes, but it is not a good idea. The check is made out to your business, so depositing it into your personal account comingles business and personal funds. The IRS may question this during an audit. Deposit business checks into your business account, even if you are the sole proprietor.
