Payroll for an LLC depends on how the LLC is taxed and whether you have employees.
A single-member LLC taxed as a sole proprietor has no payroll; the owner takes an owner’s draw from the LLC and reports the income on Schedule C. A single-member LLC that has elected S-corp has payroll: the owner-employee must be paid a “reasonable salary” through a payroll run, and the salary is subject to FICA and federal/state withholding like any other W-2 employee.
An LLC with regular W-2 employees (single-member, multi-member, or S-corp) has payroll exactly like any other employer, with the LLC or S-corp as the EIN holder on the payroll account.
Run a quick stress-test: the day you elect S-corp, your IRS obligations change.
The IRS requires that any officer (a single-member owner with employee status) be paid a reasonable salary through payroll.
Reasonable salary is what a hypothetical third-party would be paid to do the same work, less the profit distribution you take as an S-corp shareholder.
The salary goes through payroll with FICA, federal income tax withholding, state income tax, and a W-2 at year end; the profit distribution skips FICA entirely.
Payroll for an LLC starts the day the LLC elects S-corp, or the day the LLC hires its first non-owner W-2 employee. A single-member LLC without an S-corp election and without other employees does not need payroll; the owner takes owner’s draw.
Key facts: A single-member LLC without S-corp election: no payroll.
A single-member LLC with S-corp election: payroll for the owner-employee’s reasonable salary.
A multi-member LLC: owners report their share of LLC income on Schedule K-1, not on payroll (unless an owner is also an employee).
An LLC with regular W-2 employees: payroll for those employees under the LLC’s EIN.
Employer FICA match on the owner-employee’s salary is 7.65%; combined with the 7.65% employee-side FICA, the total FICA is 15.3% on the first $168,600 (2024) / $176,100 (2025) / subject to Social Security wage base adjustment each year.
An LLC owner-operator on S-corp with a $80,000 reasonable salary pays roughly $6,120 employer-side FICA in addition to the salary.
That’s $80k minus the matching FICA, paid to the employee W-2.
The remaining LLC profit is the S-corp distribution — no FICA on the distribution.
This is why S-corp election is the canonical tax optimization for an LLC whose profits are larger than the reasonable salary.
Which LLC configurations need payroll
The four configurations of LLC produce four different answers to “do I need payroll?”.
| LLC configuration | Need payroll? | Why |
|---|---|---|
| Single-member LLC, no election, no employees | No | Owner reports on Schedule C; takes owner’s draw |
| Single-member LLC + S-corp election | Yes for owner-employee | S-corp shareholder-employee requires reasonable salary via payroll |
| Single-member LLC + C-corp election | Yes for owner-employee | C-corp owner is W-2 employee of the corporation |
| Multi-member LLC | Only if employees, not for owners | Owners take distributions; income on K-1 not W-2 |
| Multi-member LLC with W-2 employees | Yes for employees | LLC files Form 941 for W-2 employees’ withholding and FICA |
For the LLC formation path itself (state of formation, registered agent, EIN, bank account), the opening US LLC as non-resident walkthrough covers those steps.
For the address half of the LLC’s public filings (registered agent, principal office), the best virtual mailbox service for small business page covers what a CMRA address unlocks.
For the receiving-money side of the LLC’s operations (how your customers pay the LLC, which processors work for ecommerce and recurring billing), the best payment processor for small business comparison runs the fee math at each card-volume tier.
The S-corp reasonable-salary requirement step by step
If your LLC elects S-corp, you owe yourself a “reasonable salary” through payroll. The mechanics are the same as any other W-2 employer-employee relationship, with the IRS watching more closely because of the FICA-saving incentive.
Step 1: elect S-corp by filing Form 2553. Form 2553 is the IRS election form. You must file it by the 15th day of the third month of the tax year for which the election takes effect (March 15 for a calendar-year LLC). Late filing is forgiven in some cases by filing Rev. Proc. 2013-30 relief, but the cleaner path is to file on time.
Step 2: open a payroll account at the LLC’s EIN. Apply for an EIN (free from IRS, 15 minutes online if you have SSN/ITIN). The EIN becomes the payroll account number with the IRS. Register with the state(s) where employees work.
Step 3: set up a payroll service. Gusto Simple ($40/month base + $6/employee) is the canonical entry-tier choice for an S-corp owner-operator. The service runs each pay cycle and files Form 941 quarterly and Form 940 annually.
Step 4: choose a reasonable salary. Reasonable is defined by industry, role, region, experience.
The IRS uses comparable salary data from the Department of Labor’s Occupational Employment Statistics, plus industry-specific compensation surveys.
For a software engineer in San Francisco running a single-member LLC: $150k-$200k is typical reasonable.
For a one-person consulting firm in Tulsa: $80k-$120k. The salary must be defensible to an IRS audit; document the rationale when you set it.
Step 5: run payroll through your service. Enter the salary each pay cycle (or each month for monthly semi-monthly or bi-monthly schedules). The service calculates withholdings, files forms, deposits taxes with the IRS and state.
Step 6: take S-corp distribution for the remaining profit. The distribution goes on Schedule K-1; no FICA is owed. The owner takes this as the LLC owner-employee’s “pass-through” income after paying the salary through payroll.
The tax math: S-corp distribution vs owner’s draw
The S-corp election makes payroll a real cost that comes with a real tax savings. The math is straightforward.
| Scenario | LLC profit, sole-prop | LLC profit, S-corp with $80k salary |
|---|---|---|
| LLC profit (Year 1) | $200,000 | $200,000 |
| Reasonable salary paid via W-2 | $0 | $80,000 |
| Self-employment / FICA on salary | SE tax 15.3% on $200k | FICA 15.3% on $80k (employee + employer split) |
| Total FICA + SE tax | $30,600 | $12,240 |
| Tax savings vs sole-prop | — | $18,360 |
That $18,360 in FICA savings is the headline reason to elect S-corp, and it’s why every “open an LLC for tax savings” article eventually reaches the S-corp conversation. The catch: payroll service costs ($800-$1,200/year), additional form filings (Form 1120-S, Schedule K-1, state-level S-corp tax filings), and the IRS-reasonable-salary audit risk add real overhead.
The breakeven point is roughly $40,000-$60,000 of net LLC profit; below that, sole-prop is the cheaper route; above that, S-corp election typically wins.
What payroll does NOT do, even for an LLC owner on S-corp
Three things payroll services do not do, even when the LLC has S-corp election and runs payroll for the owner.
Set your reasonable salary defensibly. The IRS does not provide a magic formula. Reasonable salary must be set based on industry salary data, regional wages, role complexity, and the LLC’s profit. Most business owners consult a CPA at S-corp election to set the initial salary, then revisit annually.
File Form 1120-S or Schedule K-1. Payroll services handle payroll-related forms (Form 941, Form 940, W-2, W-3). The S-corp income tax return is Form 1120-S, and Schedule K-1 reports the owner’s share. That’s a tax return, not a payroll return; it’s filed by a CPA or by the owner annually with Form 1120-S software (TurboTax Business, TaxAct Business, or a CPA).
Make state-level S-corp filings (in states that tax S-corps). Many states (California, New York, Georgia, Illinois, Tennessee, and a growing list) require a separate state-level S-corp tax return, often with a minimum franchise tax ($800 in California). Payroll services file the state payroll withholding returns but not the S-corp income tax return.
The catch with S-corp payroll: audit risk
The single biggest mistake an LLC owner makes at S-corp is paying a salary that’s too low. The IRS audits S-corps with disproportionate frequency because the FICA-savings incentive is well-known and frequently abused. If the salary is materially below what a third-party would be paid, the IRS reclassifies the distribution as salary, back-charges the FICA, and adds a negligence penalty.
The defense: document the salary decision at the time of the election. Industry data, regional wage data, comparable-role salary, and the LLC’s financials at the time all matter. Most CPAs keep a “reasonable salary memo” on file for each S-corp client.
Pick the payroll service that fits the LLC configuration
Decision rules for each LLC configuration.
Sole-prop LLC with no employees: no payroll needed. The owner takes owner’s draw, reports on Schedule C, pays self-employment tax annually via Form 1040-ES estimated payments. The Payroll service question is moot.
S-corp LLC with one owner-employee: entry-tier full service. Gusto Simple at $40/month base + $6/employee is the canonical sub-$100/month option for a single-person S-corp. OnPay at $49/month + $6/employee is the alternative with multi-state included.
LLC with multiple W-2 employees but no S-corp: entry-tier full service scaled to headcount. Gusto Simple at $40 + $6 per employee. Move to premium tier (Gusto Plus at $80 + $12) when you cross 15 employees or want HR consulting.
LLC with both owner on S-corp AND W-2 employees: premium tier or PEO. The combined cost and audit risk at this scale benefits from the per-employee fee discount and dedicated support of a higher tier or PEO.
For the cost math at each plan tier and the per-employee fee math the vendor sites hide, the payroll service cost page runs the per-state and per-add-on math.
For the broader payroll definition and why the math works, the what is a payroll service page walks through the gross-to-net and the deposits.
For the specific full-service scope (what each plan tier includes and excludes line by line), the full service payroll page covers the boundary between full-service and PEO.
For the per-vendor comparison at each tier (Gusto, OnPay, QuickBooks Payroll, Patriot Full Service, ADP RUN, Paychex), the best payroll service for small business comparison covers the realistic monthly bill at each employee count.
Verify the S-corp election details with a CPA or enrolled agent. The figure numbers in this article are from publicly available IRS wage base and Social Security Administration FICA tables, but the choice to elect S-corp and the salary amount are decisions for a tax pro, not an editorial recommendation.
