What S Corp Owners Must Do Each Year

A Big Misconception

One of the biggest misconceptions about S Corporations is that business owners simply elect S Corp status and immediately begin saving money on taxes. In reality, S Corps come with ongoing responsibilities that require organization, compliance, and consistent financial management.

At Barklee Financial Group, we often help business owners clean up S Corp issues that could have been avoided with proper planning and ongoing maintenance.


1. Run Payroll Properly

One of the most important S Corp requirements is payroll.

If the owner actively works in the business, the IRS generally expects them to:

  • Be on payroll
  • Receive reasonable compensation
  • Pay payroll taxes appropriately

This includes:

  • Payroll processing
  • Payroll tax filings
  • W-2 preparation
  • Tax deposits

Failing to run payroll properly is one of the most common S Corp compliance problems.


2. Maintain Accurate Bookkeeping

S Corps require clean, organized accounting records so bookkeeping are especially important because:

  • Owner salary and distributions must be tracked separately
  • Expenses must be documented properly
  • Shareholder basis matters
  • Financial reporting becomes more important

Poor bookkeeping can quickly create tax filing issues and increase audit risk.


3. File Form 1120-S

  • S Corporations must file: IRS Form 1120-S
  • The business also issues: Schedule K-1s to shareholders

Even though profits pass through to the owner’s personal return, the S Corp itself still files a separate business tax return.


4. Pay Attention to Quarterly Taxes

Many S Corp owners still need to make quarterly estimated tax payments depending on:

  • Business profitability
  • Payroll withholding
  • Other income sources
  • Personal tax situations

Failing to plan for quarterly taxes can lead to penalties and unexpected tax bills.


5. Keep Business and Personal Finances Separate

Business owners should maintain:

  • Separate bank accounts
  • Separate credit cards
  • Separate accounting records

Mixing personal and business expenses creates both accounting and legal problems.


6. Stay Compliant (State Requirements)

In addition to federal requirements, states may require:

  • Annual reports
  • Franchise taxes
  • State payroll filings
  • State corporate registrations


Requirements vary depending on the state where the business operates.

  • An S Corporation is not a “set it and forget it” structure.
  • The tax advantages can be meaningful, but they only work properly when the business maintains accurate records, follows payroll requirements, and stays compliant throughout the year.
