S Corporation Tax Preparation: Advantages, Requirements, and Filing Tips

Why More Business Owners Are Electing S Corporation Status

An S Corporation Tax Preparation offers one of the most effective ways for small business owners to reduce self-employment taxes, build retirement wealth, and structure their finances more strategically. But to benefit from this structure, you must follow specific IRS and state requirements—and make sure your books are clean and accurate.

Whether you’re an LLC considering S Corp election, or already operating as one, this guide breaks down everything you need to know about S Corporation tax preparation, especially for Texas-based businesses.

What Is an S Corporation Tax Preparation?

An S Corporation is not a business entity in itself—it’s a tax election that a qualifying LLC or corporation can make with the IRS using Form 2553. This election allows income and losses to pass through to the owners’ personal tax returns, avoiding double taxation.

LLC vs. S Corporation: What’s the Difference?

FeatureLLC (Default Taxation)LLC with S Corp Election
Tax FilingSchedule C (single-member) or Form 1065 (multi-member)Form 1120S
Self-Employment Tax15.3% on entire net incomeOnly on salary paid to owner paid via payroll taxes
Tax SavingsLimitedPotential savings on payroll taxes
Payroll RequirementNoYes – must pay reasonable compensation
FlexibilitySimple, minimal complianceAdditional IRS and state compliance required

Important for Texas Businesses:
In Texas, LLCs can elect to be taxed as S Corporations and still enjoy protection under state LLC laws. Texas does not require a separate S Corp designation at the state level, but franchise tax and Public Information Report requirements still apply.

Who Should Consider an S Corp?

  • Net income is consistently over $40,000 per year
  • You’re already running payroll or are comfortable doing so (don’t worry about this one – we can help you!)
  • You want to reduce self-employment taxes

S Corporation Tax Filing Requirements

Once you elect S Corp status, your business must:

  • File Form 1120S annually
  • Issue Schedule K-1s to shareholders
  • Run payroll and withhold taxes for owner-employees
  • Provide a reasonable compensation to all shareholder-employees
  • Comply with state filings, including Texas Franchise Tax

Reasonable Compensation: A Critical IRS Requirement

The IRS requires that shareholder-employees of S Corps pay themselves a reasonable salary before taking any distributions. This salary is subject to employment taxes, while distributions are not—making this the cornerstone of S Corp tax savings.

Factors to Determine Reasonable Compensation:

  • Industry standards
  • Time and effort spent working in the business
  • Comparable salaries for similar roles
  • Revenue and profitability

Underpaying yourself increases audit risk. Overpaying defeats the purpose of electing S Corp status. At Molen & Associates, we help business owners document and defend their reasonable compensation through proper benchmarking and planning.

Accountable Plans: Reimburse Without Taxing Yourself

An accountable plan allows your S Corporation to reimburse business-related expenses to employees (including owner-employees) tax-free. These include:

  • Mileage
  • Travel
  • Meals
  • Office supplies
  • Home office expenses

Without an accountable plan, reimbursed expenses may be treated as taxable income. Setting one up properly ensures compliance and boosts after-tax income.

Retirement Contributions for S Corp Owners

One of the major advantages of S Corp status is the ability to contribute more toward retirement through the business.

Common Options Include:

  • Solo 401(k): Up to $23,000 employee deferral (or $30,500 if 50+), plus 25% of W-2 wages as employer contribution, capped at $69,000 (2024)
  • SEP IRA: Up to 25% of W-2 wages, capped at $69,000 (2024)
  • Defined Benefit Plans: For high-income earners looking to contribute even more

Note: Contributions are based on W-2 salary only—not distributions. This is another reason establishing reasonable compensation is key to maximizing retirement benefits.

Bookkeeping and Tax Planning: Critical to S Corp Success

  • Maintain clean, monthly bookkeeping
  • Track shareholder basis and distributions
  • Stay current on payroll filings and tax deposits
  • Reconcile W-2 wages to 1120S returns
  • Schedule quarterly tax planning reviews

An S Corporation can quickly become a liability if compliance is ignored. Proactive planning prevents penalties, missed deductions, and reclassification risks.

Common S Corp Tax Mistakes to Avoid
  • Taking distributions without paying yourself a salary
  • Mixing personal and business expenses
  • Failing to file the annual 1120S or K-1s
  • Missing the S Corp election deadline (within 75 days of formation or year start)
  • Not tracking shareholder basis for distributions and losses
Conclusion

The S Corporation structure can provide substantial tax benefits—but only if managed properly. From payroll and accountable plans to retirement contributions and IRS compliance, it’s a powerful tool in the hands of a well-informed business owner.
