Question one: how many people will take money out?
One owner is simplest under any structure. With two or more owners, you need capital accounts, an agreement that sets how profit is shared, and per-person tracking of every contribution and distribution. Ask whether your partners are willing to keep that discipline.
If you are bringing in a partner later, ask what happens to the books at that moment, because mid-year changes in ownership mean splitting the year into periods.
Question two: will the owner be on payroll?
A sole proprietor or default single-member LLC owner is paid by draws. An S corporation owner who works is generally paid through payroll. Payroll means registering with tax agencies, depositing withholding, filing quarterly and year-end forms, and paying for software or a provider. Ask your CPA to estimate the added cost against any tax benefit.
A bookkeeper can handle the recording, but the filings have deadlines and penalties for being late.
Question three: how formal must the records be?
Corporations and LLCs benefit from separate accounts, written agreements, minutes or written consents, and annual state filings. A sole proprietor has fewer formalities but also fewer protections. Ask your attorney what happens if formalities are skipped.
State annual reports and fees apply to many entities and are easy to overlook. Put them on a calendar the day you form.
Question four: what changes in my accounting?
Each structure adds or removes equity accounts, payroll accounts and sometimes a separate tax return. Request a sample chart of accounts for each option from your bookkeeper so you can see the differences. The shape of the equity section is often the clearest sign of the structure.
Ask about the cost of a switch in year two. Converting after a year of mislabeled owner payments is harder than choosing correctly at the start.
Question five: who files what?
Make a table with three columns: the return or report, who prepares it, and the due date. Ask for it for each structure you are considering. Some structures add a business-level return, some add state taxes, and some add shareholder statements.
Once you have chosen, tell your bookkeeper in writing. They need the exact structure and any election date so they can set the books correctly from day one.
What to bring to the conversation
Bring last year's profit and loss, a list of expected owners, a rough forecast of income, and a list of any employees or contractors you plan to hire. Mention your state, since fees and filings vary. The more concrete your numbers, the more useful the advice from your attorney or CPA will be.
Ask each advisor to say what they are not covering. An attorney may not address tax, and a CPA may not address liability. Knowing the gaps tells you whom to ask next.
Common questions
Which structure is cheapest to keep up?
Generally a sole proprietorship has the least administration, but cost has to be weighed against liability and tax considerations that a professional should assess.
Can I change structure later?
Usually yes, but it can have tax and legal consequences and requires fresh paperwork and books adjustments.
Do I need an attorney or a CPA?
Often both play a role: an attorney for legal formation and liability, a CPA for tax treatment.
