Short answer: A restaurant book cleanup done in October is a project. The same cleanup started in February is an emergency with a filing deadline attached. Work backwards from the dates: W-2s and 1099s at the end of January, Form 8027 in late February or March depending on how you file, entity returns in March, individual returns in April. Everything upstream of those dates has to be finished before them, and the last clean month you have is the one that sets the pace.
This guide is the calendar. If you want the repair work itself, step by step, that is a different piece. Here we are answering a narrower question: what has to be true by when.
| Deadline | What is due | What has to be finished first |
|---|---|---|
| End of January (next business day if it falls on a weekend) | W-2s to employees, 1099-NEC to contractors and the IRS | Payroll reconciled for all four quarters, tips and occupation codes correct, contractor records complete with W-9s on file |
| Late February (paper) or end of March (electronic) | Form 8027 for large food and beverage establishments | Gross receipts and reported tips by establishment for the full year, allocated tips calculated if reported tips came in under 8 percent |
| March 15 | Partnership and S corporation returns | Every month closed, balance sheet reconciled, owner draws and distributions sorted out |
| April 15 | Individual and C corporation returns | K-1s issued, which means the entity return above actually happened |
Notice that three of the four have the same prerequisite: the books have to be closed. That is the work, and it does not compress.
Quiet. You issue W-2s and 1099s, close December on your normal timeline, hand the CPA a reconciled trial balance, and answer questions. That is the entire month.
If the above did not happen, January is when you discover that the last eight months of delivery deposits were booked as revenue, and the cleanup and the filing deadline are now running at the same time. We wrote about that scramble in how restaurants catch up before tax season.
To the last period that was both reconciled and filed on. In practice that usually means the start of the current tax year, sometimes the prior one if a return was filed on numbers that have since changed. Going further back than that is usually academic unless you are selling, refinancing, or facing an audit, in which case three years is the working assumption.
They can, at their rates, in their busiest season, without knowing your operations. You will get a filed return rather than usable books, and you will be in the same position next year.
For a single location with reasonable records, two to four weeks of concentrated work. For a small group with mixed systems and no reconciliations, six to ten weeks. Both estimates assume your bank feeds and statements are available, which is the usual bottleneck.
Bank and card statements plus vendor statements will reconstruct nearly everything. Document the method you used and be consistent. Missing paper is a substantiation problem, not a reason to stop.
Close every month. A single annual entry produces a return and nothing else. Monthly closes are what make the year comparable and what let you manage the business while it is happening.
Year end inventory, followed closely by W-9s. Both are trivial in December and expensive in March.
