A sole proprietorship is an unincorporated business owned and run by one person, with no legal distinction between the owner and the business. Because there's no separate legal entity, you and the business are legally the same person, and you remain personally responsible for all of its obligations, debts, and liabilities.
This structure is the default for freelancers, consultants, and independent contractors who start earning income without registering an entity with the state. It's easy to set up and offers complete control, but it also means your personal assets are exposed to any business claims. Before signing a high-exposure contract, identify which commitments begin with the contract and which require advice specific to your state, profession, taxes, or insurance coverage.
How a sole proprietorship works
In a sole proprietorship, contracts and federal income-tax reporting both stay tied to you. There's no entity between you and the work, so the paperwork follows the person.
Legal treatment of a sole proprietorship
Sign a client contract in your own name and the law treats you and the business as the same person. The obligations in that contract are your obligations. If a claim comes out of the work, nothing structural sits between it and your personal assets.
Client payments show up as business income on your personal return. Plenty of freelancers and consultants run this way for years—invoicing under their own name, working as independent contractors, and never registering an entity. Sole proprietorships are also common among businesses without employees.
Every client payment and business expense should tie back to an invoice, receipt, bank statement, or contract, and the running totals of income and spending are what your tax forms use to show the business's profit or loss. Clients, lenders, and the IRS all eventually ask questions those same records can answer.
If you operate under a doing business as (DBA) name, keep your legal name connected to it on contracts and tax records so the business activity stays traceable.
Tax treatment of a sole proprietorship
When a client pays you $5,000, you report that income on Schedule C attached to your personal federal return instead of filing a separate business income-tax return. If you have $1,500 in business expenses, Schedule C records both amounts to calculate your business profit. Payroll, excise, information, state, or local filings may still apply.
Schedule SE calculates self-employment tax on the profit reported on Schedule C. If withholding and credits won't cover your expected tax, you'll likely need to make quarterly estimated payments to the Internal Revenue Service (IRS). None of these forms sets money aside for you.
Self-employment tax covers Social Security and Medicare alongside income tax. It includes both the employer and employee shares because no employer pays half on your behalf.
Setting aside tax cash
Without employer withholding, you must reserve and pay taxes yourself. A deposit that lands in your account looks spendable, but you already owe part of it. Move a set percentage of every deposit into a dedicated tax account, then base each owner draw on the cash left rather than on the full deposit.
Relay's automated transfers can move that percentage into a separate tax reserve account on every deposit, so the money is already set aside when quarterly taxes come due. Sole proprietors get up to 10 checking accounts on every plan—Starter, Grow, and Scale—which means the tax reserve, operating cash, and owner draws can each live in their own account without an upgrade.
Set a recurring time to compare the reserve with your year-to-date profit and upcoming payment dates. If income or expenses change, the amount you need to reserve may change too. Keeping the reserve separate helps prevent ordinary spending from consuming cash intended for taxes.
Before an accountant review, reconcile your year-to-date income and expense totals to the supporting records. Then provide the profit calculation, estimated-payment history, reserve balance, and upcoming payment dates together. This gives the accountant the same figures used for Schedule C, Schedule SE, and the reserve review instead of requiring those amounts to be reconstructed from individual transactions.
Pros and cons of sole proprietorships
Sole proprietorships trade easy setup and direct control for personal liability and fewer documents for client onboarding. The structure can work well for low-risk solo work, but contracts, hiring, financing, or client onboarding can change that balance.
Pros
No state formation fees: You don't file entity formation documents with the state.
Complete control: No partners, boards, or operating agreements sit between you and a decision.
Relatively simple federal income-tax reporting: Business profit or loss generally flows through your personal federal income-tax return.
Easy to convert or wind down: The business itself has no entity dissolution filing, though you may need to close any DBA, licenses, permits, or tax and banking accounts you opened.
Income without corporate formalities: You don't need board minutes or distribution paperwork.
These pros hold up while the business has low liability, no employees, and little need for outside financing.
Cons
The main cons come from the lack of legal separation between you and the business:
Personal liability exposure: Insurance can cover specific risks named in a policy, but it doesn't change your legal structure or replace careful contract review. A contract can make you responsible for a specified client loss the policy doesn't cover, leaving you to pay it personally.
Harder to borrow: Without a separate legal entity or business credit history, lenders often evaluate sole proprietors primarily on personal credit and personal assets, which can limit the size and type of financing available.
Client and vendor preference for registered entities: Some larger clients and vendors prefer contracting with a registered entity. This preference often surfaces during vendor onboarding, the process a client uses to approve and document a new vendor. The client may ask for entity documents that a sole proprietor can't provide.
Before signing a high-exposure contract, mark each indemnification obligation, list the required coverage, and compare those items with the risks described in your policy documents. Where a requirement and the available coverage don't line up, name the mismatch before deciding whether to sign. Repeat that comparison whenever the contract or policy changes so anything new surfaces before you sign.
How to establish a sole proprietorship
Before client onboarding, confirm whether the client requires an EIN, proof of insurance, or an account that keeps business transactions separate, then complete the applicable steps:
Register a DBA if you'll operate under any name other than your legal name. A DBA changes the name customers see without creating a separate business entity. Your state or county sets the rules and fees.
Get the licenses or permits your state, county, or profession requires.
Get an employer identification number (EIN) from the IRS. The IRS issues it at no charge. Sole proprietors without employees often can skip it, but other IRS requirements may apply to your situation. An EIN keeps your Social Security number (SSN) off client tax paperwork. Many banking applications also ask for one.
Open a separate business account so business income and spending never mix with personal transactions. Relay is built around this split—one login, multiple checking accounts, and clear boundaries between what's business and what's yours.
Get insurance matched to the work, whether you need general liability, professional liability, or both. For a sole proprietor, insurance can help cover specific risks.
A separate business account makes tax records and any future entity change easier to manage. At year-end, mixed business and personal transactions take more work to sort. Store your EIN confirmation, DBA registration, licenses, permits, policy documents, and account records together so you can provide applicable client onboarding paperwork without searching across personal files.
When to consider switching from a sole proprietorship to an LLC
Consider switching when a contract, new hire, tax plan, client requirement, or debt changes the risk or paperwork you can accept. No single test controls the decision. The five signs below can help you decide when to request a focused review.
Five signs it may be time to switch
Contract exposure exceeds what you can accept personally. If the contract-and-policy comparison described above turns up a mismatch you can't resolve, treat it as a trigger for an LLC review.
You're hiring your first employee. Hiring means running payroll and following employment law. You may also need workers' compensation coverage for employee injuries.
Your accountant raises the question of tax structure. An LLC can choose certain federal tax treatments. The IRS calls these choices tax elections, and they may change how self-employment tax applies. Consider whether an LLC supports the plan your accountant recommends.
Entity status blocks an opportunity. Consider switching when the onboarding or financing requirement described above prevents you from proceeding.
You're taking on debt or financing equipment. Longer-term repayment obligations may make an LLC worth reviewing.
Any one of these changes can justify a focused review with the appropriate adviser before you take on the new obligation.
How to make the switch
Switching to an LLC is largely an administrative sequence, but the order matters because contracts signed under the wrong name or payments deposited to the wrong account can undermine the liability protection you're forming the LLC to gain.
File articles of organization with your state. This is the document that creates your LLC. LLC formation costs vary by state.
Apply for a new EIN if the IRS requires one for the new entity.
Update your accounts, contracts, and business records once the state approves your LLC. Put the new entity's name on invoices, payment instructions, licenses, permits, and DBA records.
Use the LLC to sign contracts, receive payments, and hold accounts so clients and agencies see the correct business name.
Time the switch around a natural break, like a new contract, renewal, or the start of a tax year, so you're not renaming accounts and reissuing invoices in the middle of active client work.
Review your structure before your next contract
Remain a sole proprietor only while the personal exposure, client requirements, and administrative work stay acceptable for the contracts you take on. Write down the decision, list the documents and accounts that need updating, assign each follow-up, and keep setup cash separate from operating cash. If the contract, insurance, hiring, or financing picture changes, review the structure again with the appropriate adviser.
If separate tax and setup cash would make the next contract easier to manage, consider starting with Relay. Sole proprietors can use up to 10 checking accounts across Starter, Grow, and Scale, while automated transfers move set percentages into tax or other purpose-based accounts on every plan.
Frequently asked questions
How is a sole proprietorship taxed?
Business profit or loss flows through to your personal federal return. You report income and expenses on Schedule C, and if net earnings from self-employment are $400 or more, you also file Schedule SE to calculate Social Security and Medicare tax on that profit. Because no employer withholds tax on your behalf, you're generally responsible for quarterly estimated payments to the IRS.
What are the disadvantages of a sole proprietorship?
There's no legal wall between you and business claims, so your personal assets can be exposed. Borrowing is often harder without a separate entity or business credit history, and some larger clients and vendors prefer contracting with a registered entity. Hiring, taking on debt, or signing higher-exposure contracts are all reasons to re-evaluate the structure.
Do I need an EIN to run a sole proprietorship?
Not in every case. You can use your SSN when no IRS rule requires an EIN, but clients or account providers may still request the federal identifier. The setup steps explain when getting one may be necessary.
Is a sole proprietor the same thing as an independent contractor?
No. Independent contractor describes your working relationship with a client, while sole proprietor describes your business structure. You can be both at the same time.
Can a sole proprietorship have employees?
Yes. The structure doesn't prevent you from hiring, though becoming an employer adds payroll and legal duties. That added workload can be a reason to reassess the structure.
Does a sole proprietor legally need a separate business bank account?
Federal law doesn't require one. Other rules or contract terms may still apply, and keeping business transactions apart can make your records easier to review. A separate account doesn't change your liability.
