Why People Choose the S-Corp — and Why Bookkeeping Gets More Complex
The S-corp election saves self-employment tax. A sole proprietor or single-member LLC owner pays 15.3% self-employment tax on all net profit. An S-corp owner pays FICA only on their salary — distributions above salary are not subject to the 15.3% SE tax. On $100,000 net profit with a $60,000 salary, the FICA savings is approximately $6,000 per year.
That saving comes with a cost: more complex bookkeeping. An S-corp must maintain payroll records, separate salary from distributions, track shareholder equity accounts, and produce Form 1120-S workpapers. This is why S-corp bookkeeping costs more — and why you should not attempt it without a qualified bookkeeper.
The 5 Things That Are Different About S-Corp Bookkeeping
| Requirement | What It Involves | IRS Consequence If Ignored |
|---|---|---|
| Owner payroll | W-2 salary, FICA withholding, quarterly Form 941, annual W-3 + W-2 by Jan 31 | IRS reclassifies distributions as wages — back FICA + penalties |
| Salary vs distribution tracking | Salary flows through payroll account; distributions recorded against shareholder equity | Commingled salary/distribution triggers audit and FICA reclass |
| Shareholder loan accounts | Any non-salary, non-distribution payment to/from owner needs a documented loan with interest | Constructive dividends — taxed as income with no basis offset |
| Shareholder basis tracking | Running annual calculation: start + income + contributions − losses − distributions | Losses claimed beyond basis disallowed; distributions over basis = capital gain |
| Form 1120-S workpapers | Trial balance, shareholder equity schedule, K-1 allocations, payroll reconciliation | CPA cannot prepare return without complete workpapers |
The Reasonable Salary Question
The IRS requires S-corp owner-employees to pay themselves a salary that is "reasonable" for the services they perform — comparable to what you would pay an outside hire for the same work. There is no formula, but here is how your CPA typically approaches it:
- Bureau of Labor Statistics wage data for your occupation and region
- Industry benchmarks (e.g., 40–60% of S-corp net profit for working owners)
- What the business would pay a replacement employee
IRS audit trigger: Zero or very low salary with large distributions is a top S-corp audit red flag. The IRS has successfully reclassified distributions as wages in many court cases. At Sharma Jyoti and Co, when we onboard an S-corp client with zero payroll, we flag it immediately and connect you with your CPA to set the right salary before the end of the tax year.

Frequently Asked Questions
An S-corp requires owner payroll (W-2 + quarterly Form 941), clean separation of salary vs distributions, shareholder loan documentation for any other payments, and annual basis tracking. The CPA needs a full shareholder equity schedule and Form 1120-S workpaper package at year-end. At Sharma Jyoti and Co we handle it from $300/month.
Comparable to what you would pay an outside hire for the same work. A common benchmark is 40–60% of S-corp net profit for working owners. Your CPA determines the right amount using BLS wage data. If the IRS determines your salary was too low, they reclassify distributions as wages — back FICA plus penalties.
The IRS reclassifies distributions as wages and charges back FICA (15.3%) plus interest and penalties on the reclassified amount. Zero salary with large distributions is a top S-corp audit trigger. We flag this on day one for every new S-corp client.
Your at-risk amount: initial investment + income + contributions − losses − distributions. You cannot deduct S-corp losses beyond your basis. Distributions in excess of basis are taxed as capital gains. Your bookkeeper tracks the running basis calculation annually as part of the year-end workpaper package.
