There are four months left in the year. Most of what fixes an S-corp return has to happen before December 31, not when you file.
That's the part that catches people. The return gets prepared in the spring, but almost every lever moved months earlier, and by then it's a records problem instead of a planning one.
Payroll is the big one. If the business income comes from your own work, the IRS expects reasonable compensation to run through payroll as wages before anything comes out as a distribution. A W-2 you meant to run and didn't isn't something your accountant can fix in March.
The rest is unglamorous. Distributions recorded as distributions. Personal charges cleaned out of the business account. Loans to and from the company documented as loans. Books reconciled through the current month, not started in January.
Let's look at an example. An owner who takes money out all year without running payroll has a tidy bank account and a real problem. Same dollars, wrong treatment.
August is when this is cheap to fix. December is when it's expensive, and March is when it turns into a conversation about amendments.
