What LLC Payroll Actually Means (And Why It’s Not Optional)
If your LLC has employees, you need payroll. That’s not a suggestion — it’s federal and state law. Payroll means calculating wages, withholding taxes, filing reports, and paying both employee withholdings and your employer taxes on time, every time.
Here’s the part that trips people up: even if you’re the only person working in your LLC, you might still need payroll. It depends on how your LLC is taxed and whether you’re paying yourself a salary or just taking draws. We’ll get into that distinction below because it matters more than almost anything else in this guide.
Ignore payroll obligations and the consequences aren’t abstract. The IRS charges penalties for late payroll tax deposits that start at 2% and climb to 15% of the unpaid amount, depending on how late you are. States pile on their own penalties for unemployment insurance and withholding tax. And if you’re a corporation or an LLC taxed as one, the IRS can hold you personally liable for unpaid payroll taxes — even though the whole point of an LLC or corporation is to protect your personal assets. That’s called “trust fund recovery,” and it’s one of the few ways your liability shield gets pierced.
What You Need to Know
The basic requirement. If your LLC has W-2 employees — including yourself, in some cases — you must withhold federal income tax, Social Security, and Medicare from their paychecks. You also owe employer-side Social Security, Medicare, and federal unemployment tax (FUTA). Most states add their own income tax withholding and state unemployment insurance (SUI) on top of that.
Does this apply to your LLC? It depends entirely on tax classification, not on the fact that you formed an LLC.
- Single-member LLC taxed as a sole proprietorship (the default): You don’t run payroll for yourself. You pay self-employment tax on your profits when you file your personal tax return. If you hire employees, though, you run payroll for them.
- multi-member LLC taxed as a partnership (the default): Same idea. Members don’t take a “salary” through payroll — they take distributions and pay self-employment tax on their share of profits. Employees you hire go on payroll.
- LLC that elects S-corp taxation: This is where payroll becomes mandatory for owners. If you’re an owner working in the business, the IRS requires you to pay yourself a “reasonable salary” through actual payroll — with tax withholding, W-2s, the works. Skip this and pay yourself only through distributions, and you’re setting up an audit target. The IRS has pursued S-corp owners for years over unreasonably low salaries designed to dodge payroll taxes.
- LLC that elects C-corp taxation: Same as any corporation. Owner-employees go on payroll.
When it’s due. Payroll isn’t an annual filing — it’s ongoing. Federal payroll tax deposits are due either monthly or semi-weekly, depending on the size of your payroll (the IRS assigns your deposit schedule based on a lookback period). On top of deposits, you file:
- Form 941 (federal quarterly payroll tax return) — due the last day of the month following each quarter
- Form 940 (federal unemployment tax return) — due annually, January 31
- W-2s to employees and the Social Security Administration — due January 31
- State withholding and SUI filings — schedules vary by state, often quarterly
What happens if you’re late. Federal penalties for late deposits scale with how many days late you are: 2% if you’re 1-5 days late, 5% for 6-15 days, 10% beyond that, and 15% if the IRS sends a notice and you still haven’t paid within 10 days. Miss Form 941 entirely and you’re looking at a failure-to-file penalty of 5% per month, up to 25% of the unpaid tax. States layer on their own penalties and interest for late SUI and withholding filings. None of this is negotiable in the way some other paperwork is — the IRS treats payroll tax debt as serious because it’s technically money you withheld from employees and are supposed to be holding in trust for the government.
How to Handle It — Step by Step
1. Determine if you actually need payroll. Confirm your LLC’s tax classification (default, S-corp, or C-corp election) and whether you have or plan to hire W-2 employees. If you’re a single-member or multi-member LLC with no election and no employees, you likely don’t need payroll — you’re paying yourself through owner draws or distributions instead.
2. Get an EIN. You need a federal Employer Identification Number before you can run payroll. If you already have one for your LLC, you’re set. If not, you can apply for free directly through the IRS, and it’s usually issued immediately online.
3. Register for state payroll accounts. You’ll typically need two separate state registrations: one for state income tax withholding and one for state unemployment insurance (SUI). Some states combine these into one application; others keep them separate with different agencies. Do this before your first payroll run, not after.
4. Choose how you’ll actually run payroll. Your options are:
- Payroll software (Gusto, QuickBooks Payroll, ADP, and similar) — handles calculations, tax deposits, and filings for a monthly fee
- A payroll service or bookkeeper who processes it for you
- Doing it manually — technically possible, but genuinely risky given how easy it is to miscalculate withholding or miss a deposit deadline
For almost every small LLC, payroll software is worth the cost. The penalties for a missed deposit deadline usually exceed a year of software fees.
5. Set up direct deposit and collect employee tax forms. Every employee fills out a federal Form W-4 and, in most states, a state equivalent. You’ll need their bank information for direct deposit and their Social Security number for tax reporting.
6. Run payroll on a consistent schedule. Weekly, biweekly, semi-monthly, or monthly — pick a schedule and stick to it. Your payroll system calculates gross pay, withholds the right taxes, and sends net pay to employees.
7. Make your tax deposits on schedule. Whether monthly or semi-weekly, deposits are typically made electronically through the IRS’s EFTPS system (or automatically, if your payroll software handles it).
8. File your quarterly and annual returns. Form 941 each quarter, Form 940 annually, W-2s at year-end, plus your state equivalents. Keep copies of everything for at least four years — that’s the IRS’s standard recordkeeping window for employment taxes.
9. If you elected S-corp status, set a reasonable owner salary. Base it on what you’d pay someone else to do your job, industry norms, and how much time you spend actively working in the business. Document your reasoning. If the IRS ever questions it, you want a paper trail showing you thought it through rather than picked a low number to save on taxes.
What It Costs
Government costs. There’s no fee to register for an EIN or most state payroll tax accounts — those are typically free. Where the cost comes in is the taxes themselves: employer-side Social Security and Medicare (7.65% of wages), FUTA (generally a small percentage on the first $7,000 of wages per employee, often reduced by state credits), and SUI, which varies by state and by your unemployment claims history — usually somewhere between 1% and 6% of taxable wages, though new employers often start at a flat rate before their history is established.
Payroll software or service fees. Expect to pay somewhere in the range of $35–$60 per month as a base fee, plus $4–$10 per employee per month. Full-service payroll providers that also handle new-hire reporting and year-end filings sit at the higher end of that range.
Penalties if you get it wrong. As covered above, late federal deposits run 2%–15% of the unpaid amount. Late 941 filings add 5% per month up to 25%. State penalties vary but often include both a flat fee and interest accruing daily. These add up fast — a single missed deposit on a modest payroll can easily cost more than a year of software fees.
Professional help. If you’d rather have someone else own this entirely, a bookkeeper or accountant running payroll for a small LLC typically charges in the range of $100–$300 per month, depending on employee count and complexity.
How BusinessFormations.com Helps
Payroll itself — the actual withholding, deposits, and filings — isn’t something we run for you. That’s specialized, ongoing work best handled by dedicated payroll software or a bookkeeper who’s watching your account every pay period.
Where we do help is everything that leads up to it and surrounds it. When you form your LLC with us, we get you your EIN, help you understand which tax classification fits your situation (including whether an S-corp election makes sense once you’re profitable enough), and keep track of the state-level compliance deadlines that often get missed — annual reports, registered agent renewals, franchise tax filings. Missing those can put your LLC in bad standing with the state, which creates its own headaches even if your payroll is perfectly clean.
Is a compliance service worth it? If you’re running payroll for even one or two employees, we think yes on the software side — the cost is small relative to the penalty risk. On the entity-compliance side, if you’re managing deadlines across one state, you can probably track them yourself with a calendar reminder. If you’re registered in multiple states or you know you tend to let paperwork slide, automated reminders and filing support earn their keep quickly.
State-by-State Differences
Payroll tax obligations vary more than people expect, mostly around SUI and state income tax withholding.
- No state income tax states (Texas, Florida, Nevada, Washington, Wyoming, South Dakota, and a few others) — you skip state income tax withholding entirely, but you still owe SUI in every one of these states.
- California — has some of the strictest and most complex payroll compliance in the country, including additional disability insurance withholding (SDI) and aggressive enforcement around worker classification. Misclassifying an employee as a contractor here carries steep penalties.
- New York — requires an additional payroll tax in some downstate counties (the MCTMT, for employers in the MTA region) on top of standard withholding.
- Pennsylvania — has local earned income taxes on top of state withholding, meaning your withholding can vary block by block depending on municipality.
Most lenient in terms of complexity tends to be the no-income-tax states — fewer forms, fewer moving pieces, though SUI registration is still required everywhere.
Multi-state challenges. If you have even one remote employee working in a different state than your LLC’s home state, you generally need to register for payroll taxes in that employee’s state too. This trips up a lot of small businesses that hire remote workers without realizing each state has its own withholding and SUI registration requirements. One employee working from a different state can mean an entirely new state payroll registration.
Common Mistakes and How to Avoid Them
Treating owner draws as payroll (or vice versa) under S-corp election. If you’ve elected S-corp status, you must run actual payroll for yourself with tax withholding. Taking only distributions to avoid payroll taxes is one of the most commonly flagged issues in IRS audits of small S-corps.
Missing the first deposit deadline because you didn’t know your schedule. The IRS assigns you a monthly or semi-weekly deposit schedule based on your payroll size. New employers often don’t realize which schedule applies until they’ve already missed a deadline.
Forgetting state SUI registration when hiring your first employee. People remember federal EIN and withholding but forget the separate state unemployment insurance registration, which is often a different agency with its own login and deadlines.
Not registering in an employee’s home state when hiring remote. As covered above, one remote hire in a new state can trigger a whole new payroll registration. Skipping it means you’re out of compliance in that state from day one.
Using a bank account instead of payroll software for a “quick fix.” Manually calculating withholding and mailing checks feels simpler at first, but it’s the easiest way to miscalculate taxes or miss a filing deadline. The cost of software is almost always lower than the cost of a mistake.
Losing track of year-end deadlines. W-2s and 1099s are due January 31 — earlier than most people expect, right after the holidays. Waiting until “tax season” to think about payroll paperwork often means scrambling to meet a deadline that’s already passed.
FAQ
Do single-member LLCs need payroll?
Not by default. If you’re taxed as a sole proprietorship, you pay yourself through draws and pay self-employment tax on your return. You only need payroll if you elect S-corp or C-corp taxation, or if you hire employees.
Can I pay myself a salary from my LLC without an S-corp election?
Not through formal payroll withholding. Under default LLC taxation, owners take draws or distributions, not W-2 salaries. Paying yourself “payroll” without the right tax election creates a mismatch the IRS will eventually question.
What’s a reasonable S-corp salary?
There’s no fixed formula, but the IRS expects it to reflect what you’d pay someone else to do your job, adjusted for your time and industry. Document how you arrived at the number.
How often do I need to make payroll tax deposits?
Either monthly or semi-weekly, based on your total tax liability during a lookback period the IRS calculates for you. Most new, small employers start on a monthly schedule.
What happens if I miss a 941 filing?
You’ll face a failure-to-file penalty of 5% per month on the unpaid tax, up to 25%, plus interest. File as soon as you can — the penalty stops growing once you do.
Do I need payroll if I only hire independent contractors?
No. Contractors aren’t employees, so you don’t withhold taxes for them. You do need to issue 1099s and be careful that they’re genuinely classified as contractors and not employees in practice — misclassification carries its own penalties.
Getting This Right From the Start
