Sole proprietorships checklist: 12 points to review in 2027

Because nothing forms a sole proprietorship, there is no filing to work through and no confirmation to wait for. What there is instead is a set of things that should be true about how you operate, and the only way to find out whether they are true is to check them one at a time.

This is that check. It is written as conditions rather than steps, because the order is not fixed and most people arrive with half of it already done.

What to take away

• Nothing on this list creates the business. It already exists. The list is about whether it is being run in a way that survives contact with a bank, a client, an insurer or a tax return.
• Four of the items come from authorities that are not the same authority, and none of them tells the others.
• The insurance line does more real work than any other line, and it is the one most often skipped.
• Anything that looks like a rule below is a question for the body named, not a statement of what applies to you.

Money and records

• A bank account used only for the business, opened in whatever name you actually trade under.
• No personal transaction in that account since it was opened, and if there has been, a note explaining it.
• Invoices going out under one consistent name, with one consistent set of details.
• Receipts and statements kept somewhere you could retrieve a specific one from a year ago.
• Some record of what the business earned and spent that is not a shoebox, checked at least monthly.
• A written note of anything you bought for the business that you also use personally, because that split has to be explained sooner or later.

The federal expectation for what a business should be able to produce is described by the IRS under business recordkeeping. Read it once. It is short, and it settles most arguments about what is enough.

Names

• If you trade under anything other than your own legal name, the name filing your state or county requires has been made.
• The name on the bank account, the invoices, the website and any filing all match.
• A search has been done for anyone else using the name in your trade, which is a separate question from availability at a registry.

What a name filing does and does not give you is set out in name filings explained, and the distinction between a registration and a right in trade is the part worth reading twice.

Permissions

• Every license and permit your activity requires, at state, county and city level, identified and held.
• Any trade or professional board registration that applies to your work.
• Where you work from checked against local rules, particularly if that is home.

Licenses follow what you do and where you do it, never what structure you chose. The SBA's overview of licenses and permits explains how the layers stack up, and each layer has to be asked separately.

Tax registrations

• Whether your situation calls for a federal identifier has been settled, rather than assumed. The reasoning is in what the number does, and the IRS issues it at no charge.
• Your state's own tax registrations checked, because state and federal are separate systems that do not tell each other anything.
• Whoever prepares your return has been asked what they need from you, and when.

Protection

• Insurance quoted for the actual exposures of your work, not for a generic version of it.
• A written note of what the cover excludes, read at the time rather than at claim time.
• Contracts that say what happens when something goes wrong: what you are responsible for, to what limit, and what the client is responsible for.

This section is short and it carries most of the weight. In a structure with no separation, insurance and contract terms are the protection, and they are the two things most often bought last.

Review triggers

Write these down, with the date you last looked.

Event	What it changes	Where to take it
Someone else works under your name	Exposure changes in kind	A lawyer, before the first job
A contract you could not absorb losing	The size of the downside	A lawyer and your insurer
Holding client money or property	A new category of risk	A lawyer, and any trade board
Working in a second state	New registrations, possibly new rules	That state's own offices
Another owner joins	You are no longer a sole proprietor	A lawyer and an accountant

Each of those is a reason to revisit the structure question rather than to answer it yourself, and the shape of that comparison is in weighing the options. If the answer turns out to be an entity, what has to be moved across is in handling the handover.

Common questions

How much of this is legally required?

Some of it, and which parts depends entirely on your work and your location. That is why every item above names a body rather than a rule. The permissions and tax sections are where genuine requirements live; the money and protection sections are practice rather than law, and they are the ones that decide how the business actually goes.

Can I do all this in a weekend?

The records, the account and the name usually yes. Licenses and insurance take longer because someone else is involved, and both are worth starting first for that reason.

What if I have been trading for years without any of it?

Then work the list in the order above and expect the permissions section to take longest. Nothing here penalizes you for arriving late, and most of it is easier to fix than to discover during a claim.

Is there anything on this list I can skip if I am very small?

The insurance line is the one people skip and the one that is least safe to skip, because it does not scale down with size. A single bad job is a single bad job whatever the turnover.

Who signs off that this is done?

Nobody. That is the honest answer and the reason to date the list yourself and look at it once a year.
