S-Corps are a favored entity structure for their combination of limited liability and passthrough taxation, which prevents double taxation. Shareholders of an S corporation receive compensation and distributions based on their roles within the company. S-Corp owners, for instance, are required to pay themselves reasonable compensation via W-2 wages before taking any distributions.

This compensation is subject to employment taxes, including for Social Security (6.2%) and Medicare (1.45%), with the employee and employer portions combined totaling 15.3% (as Federal Insurance Contributions Act (FICA) tax). If a shareholder-employee is not paid reasonable compensation, the IRS may recharacterize distributions made to the employee as compensation.

Basically, reasonable compensation refers to the amount an S-Corp owner would pay someone else to perform the same services they provide to their own business. Think of it as your “replacement cost.” 

How much would you need to pay a qualified individual to handle your responsibilities? This might vary depending on your industry, location, and the scope of work you handle personally.  Reasonable compensation is crucial because the IRS requires S-Corp owners to take a salary that accurately reflects the value of the services they perform. This prevents S-Corp owners from underpaying themselves in wages, thereby reducing their taxable income and avoiding Social Security and Medicare taxes. 

What Is Optimal Compensation for an S-Corp? 

Meanwhile, optimal compensation is a concept often discussed in tax circles as the sweet spot that minimizes tax liability. This approach focuses on adjusting an owner’s salary for the best tax outcome, not necessarily the fair market value of their work. It’s often a moving target, with suggestions ranging from keeping salaries as low as possible to pushing them higher in specific cases to maximize tax benefits. 

Optimal compensation may sound appealing, but it’s important to remember that it doesn’t always line up with the IRS’s standard of reasonable compensation. Attempting to tweak salary figures solely to minimize taxes can trigger unwanted attention from the IRS and potentially result in costly penalties. 

The Relationship Between Reasonable and Optimal Compensation 

So, can reasonable compensation for an S-Corp ever be the same as optimal compensation? In some cases, yes. If your reasonable compensation aligns with tax-efficient strategies, then your reasonable compensation is effectively your optimal compensation. 

However, they aren’t always the same. Here’s why: 

  • Reasonable Compensation Reflects Fair Market Value: Reasonable compensation is a standard set by the IRS based on what it would cost to hire someone with your skillset and duties. This figure is grounded in industry standards and professional norms, not in tax optimization optics. 
  • Optimal Compensation Prioritizes Tax Minimization: Optimal compensation, on the other hand, is a strategy that seeks to reduce taxes. Before the introduction of the Qualified Business Income Deduction (QBID), some S-Corp owners would keep salaries as low as possible to avoid payroll taxes. But QBID changed the landscape, as certain S-Corp owners now increase their salaries strategically to gain additional tax benefits. 

Why Reasonable Compensation Is Optimal for S-Corp Owners 

As tempting as it may be to fine-tune your salary to the lowest taxable figure, there’s a risk: by underpaying yourself, you can attract IRS scrutiny. The IRS’s stance is clear. Optimal compensation for tax purposes should be your reasonable compensation. 

Here’s why aligning with reasonable compensation benefits you: 

  • Reduces Audit Risk: Setting your salary at a level that genuinely reflects your contributions means the IRS is less likely to flag your tax return. Underpaying yourself, especially if done year after year, can raise red flags with the IRS, leading to audits, back taxes, penalties, and interest payments.
  • Maximizes Deductions Within Compliance: Under the QBID, some S-Corp owners saw benefits from adjusting their reasonable compensation. For example, certain thresholds and limitations apply based on W-2 wages. By paying yourself a fair wage that reflects your duties, you may find that your reasonable compensation aligns with a tax-efficient QBID strategy. 
  • Ensures Proper Retirement Contributions and Benefits: Your compensation affects contributions to Social Security, Medicare, and retirement plans. By taking a low salary, you may be inadvertently limiting your future Social Security benefits and retirement contributions. Reasonable compensation ensures that your tax contributions are balanced with the benefits you receive down the line.  

Penalties for Violating Reasonable Compensation

Despite the allure, attempting to “game” your salary can have serious drawbacks. When owners intentionally manipulate compensation, they risk unintended financial consequences. 

Some S-Corp owners try to reduce or avoid payroll taxes by setting a minimal salary. However, the IRS can reclassify funds taken as distributions instead of salary as taxable wages. This can result in significant back taxes and penalties. 

On the flip side, some push their salaries higher than necessary to maximize contributions to retirement accounts like a 401(k). While beneficial in some cases, the IRS may challenge an inflated salary if it doesn’t reasonably align with the business’s actual needs, potentially resulting in costly retirement plan penalties. 

To avoid potential issues, tax professionals and business owners should analyze the IRS guidelines and standard industry pay rates, as well as an S corporation’s gross receipts and total assets, to ensure compensation is set at a reasonable level.
