A year behind on the books? Schedule C from bank statements
It's tax time, the preparer wants your numbers, and the bookkeeping never happened. The good news: for a cash-basis sole proprietor, most of the year is sitting in your bank and card statements — it just needs to be reconstructed correctly.
What Schedule C actually needs
Schedule C is, at heart, a profit & loss statement in IRS clothing: gross receipts at the top, expenses by category in Part II, net profit at the bottom. The categories your preparer needs — advertising, contract labor, insurance, rent, supplies, utilities, and so on — map directly from a categorized P&L. What no preparer wants is a stack of raw statements at their hourly rate.
So the catch-up job is: turn twelve months of statements into categorized, reconciled totals, then let the preparer handle the judgment calls (depreciation, home office, mileage, meals limits) that statements can't answer.
The three mistakes that inflate your tax bill
- 01Counting transfers as income. Moving money from savings to checking looks like a deposit. It isn't revenue — but statement-by-statement eyeballing counts it as revenue constantly, and you pay tax on money you already had.
- 02Double-counting card spending. If you expense the credit-card payment from the bank account AND the individual purchases on the card statement, every card dollar deducts twice — an audit flag, not a bonus.
- 03Missing months. A gap in the statements is a gap in the deductions. Every account, every month, or the reconstruction understates expenses and overstates profit.
The catch-up process
- 01Download all 12 monthly PDF statements for every account business money touched — checking, savings, and business credit cards. Per-bank instructions.
- 02Categorize every transaction into income and expense buckets.
- 03Exclude transfers, card payments, and owner draws — money movement, not income or expense.
- 04Reconcile each statement to the penny.
- 05Hand your preparer the categorized P&L plus the transaction ledger (RapidPnL's Excel export), and a separate list of cash expenses, mileage, and anything that never hit the bank.
Upload the PDFs and get a management-use profit & loss in minutes — every statement reconciled to the penny. $49 for 3 months, then $9 each additional month. Full refund if we can't reconcile.
Get your P&L · $49What this costs versus the alternative
Catch-up bookkeeping services commonly price by the month — often hundreds of dollars for a year of reconstruction — and DIY in a spreadsheet costs a weekend you don't have in March. A year of statements through RapidPnL is $49 for the first three months plus $9 per additional month (about $130 for a full year), delivered in minutes with every statement reconciled, plus an Excel ledger your preparer will actually thank you for.
Common questions
For many cash-basis sole proprietors, bank and card statements capture nearly all business activity, so they're the right starting point. What statements can't show: cash income that never hit the bank, mileage, home-office use, and depreciation. Reconstruct the banked activity from statements, then add those items with your preparer.
Categorized totals, not a shoebox. A year P&L with income and expenses by category — plus the transaction detail behind it — is exactly the summary preparers work from. Handing one over usually costs less in prep fees than handing over twelve loose statements.
No — and counting them is the most expensive mistake in statement-based reconstruction, because it overstates your revenue and your tax. Transfers, credit-card payments, and owner draws are money movement, not income or expense. They must be excluded, which is exactly what RapidPnL's transfer matching does automatically.
They won't appear on business statements, so track them separately and give the list to your preparer. If a personal card carried real business spending, its statements can be included so those expenses are captured.
No. It's a management-use, cash-basis P&L reconstructed from your statements — the organized starting point you or your preparer maps onto Schedule C, adding non-bank items like mileage and depreciation. It is not tax advice and not a substitute for a preparer's judgment.
