The P&L your tax preparer is asking you for
A preparer asking for a profit and loss is asking for the totals that go onto your return, sorted the way the return sorts them. For a sole proprietor those totals land on Schedule C, which is literally titled Profit or Loss From Business, and the categories on it are the categories your preparer needs — gross receipts, then expenses broken out by kind. They are not asking for something formal. They are asking for numbers they can rely on, with supporting records behind them, because whatever gets filed has to be substantiated if the IRS ever asks.
Why they want it from you rather than building it themselves
A preparer can only report what you tell them happened. They were not there when you spent the money, and a bank statement on its own does not say whether a payment was materials, a repair, or something personal. Somebody who was there has to say which, and that somebody is you.
This is also why preparers charge more when you hand over a shoebox instead of totals. Sorting a year of transactions is work, it is billable, and it is work you can do or have done more cheaply than at a preparer's hourly rate.
The IRS publishes what it expects a small business to be able to show, and the through-line is that your records exist to support the figures on the return. A profit and loss is the summary; the statements and receipts underneath it are what makes the summary defensible.
What has to be true about the numbers you hand over
They have to cover the whole tax year, not the months you happen to have. A year with three months missing produces a return that understates or overstates, and the gap is the first thing that unravels later.
They have to separate money that arrived but is not income. Transfers between your own accounts, money you put into the business yourself, and loan proceeds all land in the bank looking exactly like sales. Counting them as revenue inflates your income and you pay tax on money you did not earn.
And they have to be consistent with anything else you have already given anyone — a lender, a landlord, a previous year's return. Two different profit figures for the same year is the problem that takes the longest to explain.
If you have statements but no books
That is a normal situation and it is solvable, because the bank statements are a complete record of what moved. Every dollar the business received and spent through that account is on them, in order, with dates.
The work is deciding what each line is, grouping the lines into the categories the return uses, and totalling them by month so the year adds up. Doing it month by month rather than as one pile is what makes errors visible — a month where meals triple or revenue halves is usually a miscategorised transaction rather than a real event.
Hand your preparer the summary and keep the statements. They will ask about specific lines, and being able to point at the transaction behind a total is the whole reason the summary is worth anything.
Upload one statement and see the categories before your preparer bills for them. Start from your bank statements.
Questions people ask
Does a tax preparer need a formal profit and loss statement?
Usually not a formal one. What a preparer needs is reliable totals sorted into the categories the return uses, with supporting records behind them. A clear summary by month, produced from your bank statements, answers the request as well as anything more elaborate would.
Can my preparer just use my bank statements?
They can work from statements, but somebody still has to say what each transaction was, and only you know that. Preparers generally bill for that sorting work, which is why handing over categories and totals rather than raw statements usually costs less.
What if some deposits were not income?
Then they must be separated out before the totals mean anything. Transfers between your own accounts, money you put in yourself, and loan proceeds all look like sales on a bank statement, and counting them as revenue means paying tax on money the business never earned.
What if I am missing part of the year?
Get the missing statements from the bank before you file rather than estimating around the gap. A year with months missing produces totals that do not reflect the business, and the gap is the thing that becomes expensive to explain later.
