The short answer: get every statement first, reconcile month by month starting with the oldest, settle shareholder-employee payroll before you touch owner money, then sort what the owner took out into wages, distributions and loans, and end with a short list for your CPA. The order is the point. Each step produces something the next one needs, and catching up out of order means sorting the same transactions twice.
Collect, for the full period: statements for every bank and card account (including closed ones and any personal card the business used), payroll reports, loan and lease statements, the prior year’s closing trial balance or return from your CPA, and a list of every account the owner pays business bills from. Missing statements are the usual reason a catch-up stalls in month eight, so find them now. If you want the wider picture first, our catch-up bookkeeping page and the cost of catching up a year guide cover scope and effort.
Start from the prior-year closing balances and reconcile each account to its statement, one month at a time, before moving on. If the opening balance does not agree with the last return or closing trial balance, stop and find out why; do not plug the difference. A reconciled month that is wrong will carry into every later month. The review checklist shows what to look for in the finished months, and the month-end close checklist is a good template for signing each month off.
Before you classify any owner money, confirm what the shareholder-employee was paid through payroll. The IRS states: “S corporations must pay reasonable compensation to a shareholder-employee in return for services that the employee provides to the corporation before non-wage distributions may be made to the shareholder-employee” (IRS, S Corporation Compensation and Medical Insurance Issues, reviewed 3 March 2026). The same page says the IRS has the authority to reclassify payments from non-wage distributions to wages. We do not tell you what number is reasonable; that is a question for your CPA. What the bookkeeping must show is what was actually run through payroll, by period. If payroll was missed for months, flag it now, because everything in Step 4 depends on it. Our owner and officer compensation guide covers the QuickBooks payroll side.
List every transaction between the business and the owner for the year, then give each one exactly one home:
| Bucket | What belongs in it | Where it lives |
|---|---|---|
| Wages | Pay run through payroll | Payroll expense and liabilities |
| Distributions | Money taken out as an owner, with no loan terms | Equity |
| Shareholder loans | Money the owner put in to cover the business, or took out with a repayment expectation | Balance sheet liability or asset |
Anything you cannot place with confidence goes on a question list for the CPA. A guess that is wrong costs more to unwind than an open question costs to ask.
For each business loan, take the lender statement and split each payment into principal and interest. A payment booked entirely to expense overstates costs and leaves the loan balance wrong; one booked entirely against the loan hides the interest. Tie the ending balance to the lender’s year-end figure.
With bank and card accounts reconciled, payroll confirmed and owner money sorted, scan each month for uncategorized items, duplicate bills and anything sitting in a catch-all account. Resolve or list it, then move to the next month.
Your CPA prepares the return. The IRS describes Form 1120-S as the form used “to report the income, gains, losses, deductions, credits, etc.” of an S corporation (IRS, About Form 1120-S, reviewed 21 July 2026). Ask your CPA for the filing and extension dates that apply to your situation; we have not restated them here.
Illustrative only. An S-corp owner brings twelve months of books. After reconciling, the bookkeeper lists eighteen transfers to the owner. Eleven are clearly distributions, four are repayments of a loan the owner made to the company, and three have no explanation. The first fifteen are booked. The three go on the CPA’s question list with dates and amounts. The payroll summary shows the owner was paid wages in only nine of the twelve months, which goes at the top of the same list.
Each step feeds the next. Reconciled bank and card accounts tell you which owner transfers actually happened, owner payroll decides which of them can be distributions, and only then can the remaining transfers be sorted into distributions or loans. Doing them out of order means re-sorting the same transactions twice.
Not safely. The IRS says S corporations must pay reasonable compensation to a shareholder-employee for services before non-wage distributions may be made, and that it can reclassify payments from distributions to wages. Put transfers you cannot explain on a question list for your CPA rather than guessing.
The trial balance, signed-off bank and card reconciliations, a payroll summary showing shareholder-employee wages, a list of every shareholder transaction by bucket, loan schedules and your question list. Ask your CPA for the filing and extension dates that apply to your return.
No. This is a bookkeeping sequence. Your CPA decides how items are treated on the return, including shareholder basis and officer compensation.
