E-Commerce Sole Prop to S-Corp Entity Restructuring

The Problem

This client had built a thriving e-commerce business selling specialty outdoor equipment through their own website and third-party marketplaces. With $1.2 million in annual revenue and roughly $384,000 in net profit, they were filing everything on Schedule C as a sole proprietor and paying full self-employment tax on the entire amount.

Their prior CPA had never raised the question of entity restructuring. The client was paying approximately $29,000 per year in unnecessary self-employment taxes alone. Beyond that, they had no retirement plan, no accountable plan for business expense reimbursements, and no strategy for separating business and personal finances in a tax-efficient manner.

The client came to AE Tax Advisors after reading about S-Corp elections online but was unsure whether the savings would justify the additional compliance costs and payroll requirements.

AE Tax Strategy

1. S-Corp Election Under IRC §1362

We filed Form 2553 to elect S-Corporation status under IRC §1362. By establishing a reasonable compensation of $120,000 (supported by comparable salary data for e-commerce operations managers in the client's market), we removed approximately $264,000 from the self-employment tax base. At the combined 15.3% FICA rate, this produced immediate payroll tax savings of approximately $24,800 per year.

2. Solo 401(k) with Employer Match Under IRC §401(a)

With the S-Corp in place, we implemented a Solo 401(k) plan under IRC §401(a). The client contributed the maximum employee deferral of $23,500 and the S-Corp made an employer contribution of 25% of W-2 wages ($30,000), sheltering a total of $53,500 from current-year income taxation. At the client's marginal federal rate of 32% plus state-equivalent savings, this produced approximately $17,100 in income tax reduction.

3. Accountable Plan Under IRC §62(a)(2)(A)

We established a compliant accountable plan under IRC §62(a)(2)(A), allowing the S-Corp to reimburse the client for home office expenses, business use of vehicle, internet, cell phone, and travel costs that had previously been non-deductible personal expenses post-TCJA. This shifted approximately $16,000 in annual expenses from personal non-deductible to corporate deductible, producing an additional $5,100 in tax savings.

Before & After Comparison

Key Takeaways

• Sole proprietors with consistent net income above $80,000 should evaluate S-Corp election for self-employment tax reduction under IRC §1362.
• Reasonable compensation must be documented and defensible — we use industry salary surveys and comparable data to support the W-2 amount.
• Retirement plan contributions through an S-Corp create both income tax deferrals and wealth accumulation that a sole prop alone cannot optimize.
• Accountable plans restore deductions eliminated by the Tax Cuts and Jobs Act for unreimbursed employee business expenses.
