S-Corp Tax Strategies
How S-corporations reduce payroll taxes and what compliance steps are required.
S-corporations can reduce payroll taxes by splitting income into salary and distributions, but they come with stricter compliance requirements.
Key Takeaways
- S-corps require reasonable W-2 compensation.
- Distributions may avoid payroll taxes.
- Payroll setup and bookkeeping must be more formal.
Why S-Corps Can Save Taxes
Payroll taxes apply to wages, not distributions. By paying a reasonable salary and taking remaining profit as distributions, total payroll tax can drop.
How the Savings Work
Social Security tax applies to wages up to $176,100 (2025) or $183,000 (2026). Medicare tax of 2.9% has no cap. When you take profit as distributions rather than salary, you avoid both taxes on the distribution amount.
Example: Your LLC earns $150,000 in profit.
| Scenario | Salary | Distribution | SE/Payroll Tax |
|---|---|---|---|
| Sole Prop (no S-corp) | N/A | N/A | ~$21,194 (15.3% on 92.35%) |
| S-corp, $70,000 salary | $70,000 | $80,000 | ~$10,710 (15.3% on salary only) |
| Savings | ~$10,484 |
Reasonable Compensation
The IRS requires S-corp owners who perform services to take a reasonable salary before distributions. Factors that determine reasonable compensation include:
- Industry salary data for your role
- Hours worked and responsibilities
- Company revenue and profitability
- Geographic location
- Training and experience
Tip: Document your salary rationale. Use salary surveys (BLS, Glassdoor, PayScale) and keep written records.
Compliance Must-Haves
- Run payroll and file payroll tax forms (quarterly Form 941, annual Form 940).
- Maintain clean books separating personal and business finances.
- Document the basis for salary decisions.
- File Form 1120-S by March 15 (calendar year S-corps).
- Issue K-1s to all shareholders.
QBI Deduction Interaction
S-corp owners may also qualify for the Qualified Business Income (QBI) deduction of up to 20% on pass-through income. However, the QBI deduction applies to business income after subtracting reasonable compensation. Higher salary means a lower QBI deduction, so there is a balancing act. See the QBI deduction guide for details.
Common Forms
- Form 1120-S for the S-corp return
- Form W-2 for owner compensation
- Schedule K-1 for pass-through income to shareholders
- Form 941/940 for payroll taxes
