The Problem
This client had formed a single-member LLC in early January to operate a growing digital marketing agency. The client's attorney had mentioned the possibility of an S-Corp election but never filed the paperwork, and the CPA who prepared the prior year's return did not raise it either. By the time the client came to AE Tax Advisors in September, the March 15 deadline for filing Form 2553 had passed by six months, and the client had already earned $210,000 in net profit on which full self-employment tax was being accrued.
The client believed the opportunity was lost for the entire tax year and was resigned to paying approximately $23,800 in self-employment tax on projected net income of $280,000. The client was unaware that the IRS provides multiple avenues for late S-Corp elections, including Rev. Proc. 2013-30 (for elections filed within 3 years and 75 days of the intended effective date) and the reasonable cause standard under Treas. Reg. §301.9100-3. The prior advisors' failure to file was itself reasonable cause for the late election.
AE Tax Strategy
1. Late S-Corp Election Under Rev. Proc. 2013-30
We prepared and filed Form 2553 with a statement requesting late election relief under Rev. Proc. 2013-30, Section 4.01. The filing included a detailed explanation that the sole member intended to elect S-Corp status at formation, that the failure to file timely was due to the member's reasonable reliance on professional advisors who failed to act, and that the LLC had no prior tax returns filed inconsistent with S-Corp treatment. The election was approved retroactive to January 1, effectively treating the entire year as an S-Corp year. We established payroll with reasonable compensation of $72,000 based on comparable digital marketing agency owner-operators in the Florida market.
2. Payroll Setup and Reasonable Compensation Analysis Under IRC §3121
With the late election approved, we retroactively set up payroll and issued catch-up W-2 wages of $72,000 for the year. This removed $208,000 from the self-employment tax base. The FICA savings at 15.3% on the difference (capped at the Social Security wage base, with 2.9% Medicare on the full amount) totaled approximately $14,600. We documented the reasonable compensation with a formal analysis referencing PayScale data, Glassdoor salary comparisons, and Bureau of Labor Statistics occupational data for advertising and marketing managers.
3. Solo 401(k) Implementation Under IRC §401(a)
With the S-Corp election in place, we established a Solo 401(k) before the December 31 plan establishment deadline. The client contributed $23,500 in employee deferrals plus an employer contribution of 25% of W-2 wages ($18,000), sheltering $41,500 from current taxation. At the 24% federal marginal rate (no state income tax in Florida), this produced $4,400 in additional net tax savings after accounting for the payroll processing costs of approximately $1,800 for the remainder of the year.

|---|---|---|---|
| Self-Employment / FICA Tax | $23,800 | $9,200 | $14,600 |
| Retirement Plan Tax Savings | $0 | $4,400 | $4,400 |
| Total | $23,800 | $4,800 | $19,000 |
Key Takeaways
- Missing the March 15 S-Corp election deadline is not fatal — Rev. Proc. 2013-30 provides a straightforward path to late election relief when reasonable cause exists.
- Reliance on a professional advisor who failed to file is itself a recognized form of reasonable cause under both Rev. Proc. 2013-30 and Treas. Reg. §301.9100-3.
- Late elections can be filed up to 3 years and 75 days after the intended effective date, meaning some business owners can recover multiple years of overpaid self-employment tax.
- The Solo 401(k) plan establishment deadline is December 31, but contributions can be made until the tax return filing deadline — creating a narrow but valuable window for late-year planning.
