Multi-Member LLC or S-Corp? Revisiting the Entity Question for 2027
The multi-member LLC versus S-corp question isn't a decision made once and forgotten. With a new tax year approaching and profits shifting for many businesses, this is a reasonable time to revisit whether the current structure still fits, rather than assuming the original choice is still the right one.
The Core Difference: Self-Employment Tax
A multi-member LLC taxed as a partnership generally passes business income through to the members, but the self-employment tax result depends on the member's status and the nature of the income. General partners and many active LLC members can have substantial amounts subject to self-employment tax, while section 1402(a)(13) and related authority can produce different results for some limited-partner-type interests. It is not accurate to assume every active member's entire distributive share is automatically subject to self-employment tax. An S-corp, by contrast, only subjects the shareholder-employee's reasonable W-2 wages to payroll tax; profit distributed beyond that reasonable salary generally isn't subject to self-employment or payroll tax at all. This difference is the entire reason the S-corp structure is attractive for profitable service businesses.
Where the Savings Actually Show Up — and Where They Don't
The payroll tax savings from an S-corp election only materialize once profit is comfortably above a reasonable salary for the work being done. For a business with modest profit, the added cost and complexity of running payroll, filing a separate corporate return, and maintaining more formal recordkeeping can outweigh the tax savings entirely. There's no fixed profit threshold where the switch automatically makes sense — it depends on what a reasonable salary would actually be for the specific role, which varies significantly by industry and responsibilities.
What an S-Corp Election Doesn't Change
Electing S-corp treatment for federal tax purposes doesn't change the underlying LLC or its state-law liability protections — it's a federal tax election layered on top of the existing entity. An eligible LLC that timely files Form 2553 generally does not also need a separate Form 8832; the S election can carry a deemed election to be treated as a corporation. It also introduces new administrative obligations: payroll for the working owners, a separate Form 1120-S, and generally more attention to formalities like properly documented distributions and reasonable compensation.
The QBI Deduction Adds Another Layer
Because the qualified business income deduction interacts with W-2 wages paid by the business, the entity choice and the QBI calculation aren't independent decisions — increasing salary to satisfy reasonable compensation can, in the right situation, also affect the QBI wage limitation for higher earners. This is one more reason the analysis needs to run actual numbers rather than a rule of thumb.
Why Now Is a Reasonable Time to Revisit It
An S-corp election generally needs to be made within 2 months and 15 days of the start of the tax year it's meant to cover, which means a decision for next year needs to happen well before next March if it's going to apply to the full year. Revisiting the analysis now, with a real profit projection for this year in hand, gives enough lead time to actually implement a change if the numbers support it.
