An S-Corp can save your small business quite a bit in self-employment taxes, but there are definitely some drawbacks and things to watch out for. Here are three of the biggest drawbacks involved in converting to or becoming an S-Corp—because no one likes discovering problems after it’s too late.
It’s like that scene in The Wedding Singer when Adam Sandler’s character gets stood up at his own wedding. The next day, his ex-fiancé tells him she never loved him, and he shouts: “Again, that’s something that should have been brought to my attention… YESTERDAY!”
So let’s make sure you know the drawbacks before diving into S-Corp status. Let’s dive into the key drawbacks of S-Corps that many people only learn about too late.
1 – The Formalities Can Be a Headache
S-Corps come with legal and tax compliance requirements that you need to stay on top of.
a. Accounting and Bookkeeping for Salary and Distributions
You’re required to take a “reasonable salary” based on your net profit, and then you can take the remaining profits as a distribution. To make these decisions properly, you need accurate, up-to-date bookkeeping and accounting.
At Nuance Financial, we manage this for our clients by connecting them to QuickBooks Online and keeping books updated weekly.
b. Payroll Systems Are Mandatory
Because the IRS is strict about Social Security and Medicare tax compliance, you’ll need a formal payroll system. ADP and Intuit are solid options (and we offer wholesale pricing).
Unlike DIY setups, we provide full-service payroll as part of an all-in-one monthly service—bookkeeping, taxes, payroll, and strategy—at a price that often beats piecing it all together.
c. More Complex Tax Returns (Form 1120S)
You’ll need to file an 1120S return, which can cost anywhere from $200 to $1,500 depending on your tax preparer.
We include this as part of our monthly fee, so there are no surprises.
d. Legal Requirements
S-Corps also come with legal formalities—Board of Directors, shareholder meetings, operating agreements, stock issuance, and more.
While we’re not attorneys, services like LegalZoom or a local business lawyer can help you get set up.
2 – Reduced Social Security Benefits
Your Social Security retirement benefits are based on your salary—not your distributions.
Since S-Corp owners lower their self-employment taxes by minimizing salary and maximizing distributions, this means you’ll likely pay less into Social Security over time. And that means a smaller benefit later in life.
To qualify for Social Security, you need 40 work credits (roughly 10 years of work), and your benefit is based on your 35 highest-earning years. In an S-Corp, only your W-2 salary counts toward this.
The good news? You can invest the tax savings in better-yielding options like a Solo 401(k), rental properties, or index funds.
Just make sure you’re intentionally planning for retirement—because the government won’t be doing it for you.
3 – Limits on Retirement Contributions and Mortgage Approvals
Here’s what else gets tied to your W-2 salary:
a. Retirement Contributions
If you want to max out a Solo 401(k), SEP IRA, or Defined Benefit Plan, the amount you can contribute is largely based on your salary—not your distributions.
For example, with a Solo 401(k), employer contributions are a percentage of your W-2 income, up to annual limits. So if your salary is low, you’ll hit those limits faster.
Want to contribute more? You’ll need to increase your W-2 salary—which also increases your payroll tax liability.
b. Home Loan Approvals
When applying for a mortgage, lenders usually only consider your salary—not your S-Corp distributions. Business income often needs to be seasoned for two years before it counts.
So if you’re hoping for a high mortgage approval, know that a lower W-2 salary could limit your borrowing capacity.
Some private lenders or small banks may consider the full picture, but that often comes with higher interest rates.
Our advice: plan ahead. Save more. Don’t stretch for a mortgage just out of reach because of your S-Corp setup.
In Summary
Here are the three major drawbacks of S-Corps:
- Tax and legal formalities (bookkeeping, payroll, 1120S, legal structure)
- Lower Social Security benefits (due to reduced salary)
- Retirement contribution and mortgage approval limits (based on salary, not distributions)
