When and How to Set Up Payroll for Your Business: CPA’s Timeline
Table of contents
When do you have to set up payroll? Before the first paycheck, which in practice means before your employee’s first day of work, and the safe plan is to start four or more weeks ahead.
The first paycheck lands on a fixed date. Your federal tax ID and state accounts have to exist before it, and your state’s processing time decides how early you start. So the work starts by counting backwards from payday.
We don’t run payroll ourselves. Our clients go to Jen Stevenson Payroll, and our advice to every owner is the same: use full-service payroll. Full service means the provider calculates each paycheck, deposits the taxes, files every federal and state payroll return, and cleans up when something goes wrong. Your part is sending in hours and any changes each pay period.
The Short Answer: Set Up Payroll Before Your Employee’s First Day
Starting four or more weeks ahead gives your state accounts time to arrive before anyone gets paid.
| Your situation | Do you need payroll? | When to set it up |
|---|---|---|
| Hiring your first W-2 employee | Yes | Before their first day, ideally 4 or more weeks ahead |
| S-Corp owner who works in the business | Yes, for your own salary | Before your first owner paycheck, and before the S-Corp election takes effect where possible |
| Sole proprietor or single-member LLC (default tax treatment), no employees | No payroll for yourself | When you hire your first employee |
| Partner in a partnership | No payroll for yourself | When you hire employees |
| Paying independent contractors only | No payroll, but you must classify them correctly | Review classification before the first payment |
| Switching providers | Already running | Start of a year or quarter where possible |
| Adding a state | Already running | Before the first wages paid in the new state |
When You Need Payroll: The Situations That Make It Mandatory, and the Ones Where You Can Skip It
You Hire Your First W-2 Employee, Even Part-Time, Seasonal or a Family Member: Payroll Is a Must
Working part-time or for one season doesn’t make someone a contractor. Whether a worker is your employee depends on the whole relationship, and no single fact decides it. The IRS groups the evidence into three areas: whether you control how the work gets done, whether you control the business side of the job, such as how the worker is paid and who covers expenses, and how the two of you treat the relationship, such as contracts and benefits. Our guide to contractors versus employees walks through the full test. (irs.gov)
A spouse you employ goes on payroll with full withholding, Social Security, and Medicare. In an unincorporated business, a spouse who shares ownership, control, and the work with you is a co-owner, not an employee, and the rules for sole proprietors and partners below apply. (irs.gov)
A child under 18 who works in a parent’s sole proprietorship is still a payroll employee: exempt from Social Security and Medicare, but not from income tax withholding. (irs.gov)
You Are an S-Corp Owner Who Works in the Business: Your Pay Must Run Through Payroll
If you work in the business, the S-Corp has to pay you reasonable compensation, meaning a salary in line with what the company would pay someone else to do your job, as wages. Only after that can you take distributions, the profit you take out on top of your salary. (irs.gov)
Our reasonable salary guide walks through how we set that number.
You Are a Sole Proprietor, Partner or Default Single-Member LLC Owner: You Take Draws, Payroll Isn’t Mandatory
Owners in these structures are self-employed, and the business can’t treat them as its own employees, so there’s no paycheck to run. You take owner draws instead, and you pay self-employment tax on the profit through quarterly estimated payments and your return. (law.cornell.edu)(irs.gov)
But when you hire your first employee, payroll starts for that employee, and you still stay off it yourself. Our comparison of sole proprietorships, LLCs, S-Corps, and C-Corps lays out how each one pays its owner.
You Only Use Independent Contractors: No Payroll, but Misclassification Can Create Payroll Tax Liability You Should Be Aware Of
Paying contractors keeps you off payroll only if they really are contractors. The central question is control. If you decide what a worker does and how the worker does it, that person is likely your employee, whatever the agreement calls them.
Misclassify an employee as a contractor and you can owe the Social Security, Medicare, and income tax you didn’t withhold. And contractors you pay get Form 1099-NEC, not a W-2. (irs.gov)
Some states add a reporting step even for contractors. Virginia, for one, requires you to report each new independent contractor within 20 days of the contract’s start. (law.lis.virginia.gov)
Our guide to contractors versus employees covers the control test.
You Hire in Another State: New Registrations and Unemployment Accounts May Be Required
An employee working outside your home state can bring a second set of state accounts, and your business may also have to register in that state as a foreign entity; our article on state income tax covers the registration risk. Before you pay the first wages there, find out which state’s withholding and unemployment accounts you need. Reciprocity agreements, which let some workers pay income tax only to the state they live in, and the rules about where the work is performed can change the answer, and a full-service provider checks this for you. (tax.virginia.gov)
When to Set Payroll Up in Practice: A Timeline That Works Backwards From Your Employee’s First Paycheck
Count back from the first payday, because each step depends on the one before it:
| When | What to do | Why it matters |
|---|---|---|
| 4 or more weeks before the first day | Get your EIN, register for state withholding and unemployment accounts, arrange workers’ compensation, and decide how you will run payroll | State accounts can take days or weeks, depending on the state, and payroll setup needs them |
| 2 weeks before | Choose your pay schedule, send new-hire forms, and complete onboarding with your payroll provider | Setup can take from a day to about two weeks, depending on the provider |
| First day and first week | Collect Form W-4, complete Form I-9 (Section 1 by the first day, Section 2 within three business days), gather direct deposit details, enter the employee in payroll | The W-4 sets withholding from the first check, and the I-9 has fixed deadlines |
| Within 20 days of hire, or sooner if your state says so | File the new-hire report, the notice that tells your state you hired someone | Federal law sets 20 days, and states can set less |
| By your provider’s cutoff before payday | Run payroll early if paying by direct deposit | Direct deposit settles the same day or one to two business days after the provider submits it |
| After the first payroll | Schedule your first federal and state tax deposits and put quarterly and annual filings on the calendar | The first payroll starts your deposit and filing clock |
An EIN, your employer identification number, is the federal tax ID that every business reporting employment taxes needs, and the IRS issues one immediately when you apply online. (irs.gov)
But state accounts take longer. Registration times vary by state, and California says mail-in registrations take 10 to 14 days. (edd.ca.gov)
And most states require workers’ compensation once you have employees, and each state sets its own trigger. Virginia requires it once you have more than two employees. (workcomp.virginia.gov)
Form I-9, the federal form that verifies a new hire can legally work in the U.S., has two hard deadlines:
- The employee completes Section 1 by the first day of work.
- You complete Section 2 within three business days of the start date. (uscis.gov)
The new-hire report runs on its own deadline. Federal law gives you 20 days from the hire date and lets each state set its own deadline. Iowa, for example, uses 15 days. (law.cornell.edu)(legis.iowa.gov)
ACH payments, the bank transfers behind direct deposit, settle the same day or one to two business days after the provider submits them, depending on the provider’s cutoff. So you run payroll by your provider’s cutoff. (nacha.org)
The Best Time of Year to Start or Switch to a Payroll
Starting Payroll: Whenever You Need It, and There Is No Catch-Up to Do If You Have Never Paid Employees
A business that has never paid anyone has no wage history to move, so any month works. The same four weeks for your EIN, state accounts, and provider onboarding still apply.
Switching Payroll Providers: Try to Time It
Moving from one provider to another is easiest at the start of a year, then at the start of a quarter:
- January 1 is the best to avoid migrating historical data
- Start of a quarter: the 2nd best option
- Mid-quarter: the messiest you should try to avoid
What counts is the first pay date of the new year or quarter, not the calendar date. A January 3 payday is still the year’s first payroll. Mid-quarter is the hardest because the new provider needs both providers’ records to file that quarter’s returns. (gusto.com)
Aligning Your First Owner Paycheck With an S-Corp Election Date
Your S-Corp election, the filing that tells the IRS to tax your company as an S-Corp, is made on Form 2553. You file it no more than 2 months and 15 days after the start of the tax year the election takes effect. (irs.gov)
Set owner payroll up before the S-Corp election takes effect, with wages starting on that date. Filing Form 2553 late is possible if you qualify for the IRS’s late-election relief, but talk to us first: a late election raises the question of the salary you didn’t take for the earlier months.
How to Set Up Payroll, Step by Step
Step 1: Get an EIN and Register for Federal and State Employer Accounts
Your EIN comes back immediately when you apply online, and your state withholding and unemployment accounts follow. Federal tax deposits must be made electronically, through EFTPS (the Electronic Federal Tax Payment System, the IRS’s online payment system, where you may already be enrolled from your EIN application), IRS Direct Pay, or an IRS business tax account. (irs.gov)
Step 2: Decide Who Will Run Payroll
Pick a full-service option: one that calculates pay, deposits the taxes, and files every return for you, whether that’s a payroll company or software on a full-service plan.
Step 3: Pick a Pay Frequency That Fits Your Cash Flow and Your State’s Pay-Frequency Rules
States set minimum pay frequencies, and your schedule has to meet yours. Virginia, for example, requires salaried employees to be paid at least once a month and hourly employees at least every two weeks or twice a month. (law.lis.virginia.gov)
Step 4: Collect Form W-4, Form I-9, Direct Deposit Authorization and Any State Forms Before the First Payroll
Form W-4 is the employee’s federal withholding certificate, and you ask for it when the employee starts. It governs withholding from the first wage payment. Does a missing W-4 stop you from paying? No. Without one, you withhold as if the employee checked Single or Married filing separately with no other entries. (irs.gov)
Collect the direct deposit authorization and your state’s withholding form, if it has one, before the first payroll runs.
Step 5: Enter Wages, Deductions, Benefits and Time-Off Policies
Before the first run, your provider sets up pay rates, retirement contributions, garnishments, health premiums, reimbursements, and paid time off from what you give it.
Step 6: Consider a Dedicated Payroll Bank Account So Taxes and Wages Are Never Mixed With Operating Cash
Do you need a separate payroll account? No federal rule requires one, but we recommend it. Because the withheld taxes sit apart from operating cash, you can see at a glance that the tax money is untouched until it’s deposited.
Step 7: Run the First Payroll Early, Review Every Line, and Confirm That Tax Deposits Are Scheduled
The first run is where setup errors show up. Check each paycheck’s gross pay, every withholding line, the net pay, and the employer taxes against what you expected, and confirm your first tax deposit date.
Step 8: Calendar the Ongoing Work
Confirm that your provider already has these dates:
- Monthly federal tax deposits in your first calendar year
- Form 941 on April 30, July 31, October 31, and January 31
- Form 940, the annual federal unemployment tax return, by January 31
- W-2s to employees and the Social Security Administration by January 31
When January 31 falls on a weekend, as it does in 2027, those deadlines move to the next business day. Form 941 is quarterly unless the IRS tells you to file the annual Form 944 instead. (irs.gov)
Setting Up Payroll for Yourself as an S-Corp Owner: Key Considerations
Set a Reasonable Salary First, Then Run It on a Regular Schedule
An S-Corp has to pay you reasonable compensation as wages before you take distributions, so the salary figure comes before the first owner paycheck. (irs.gov)
Why Distributions Alone Are Not Enough When You Work in the Business
Distributions aren’t wages, and when an owner who works in the business takes no salary, the IRS can treat those distributions as wages and assess the payroll taxes.
How to Choose a Salary and a Pay Frequency That Fit a Single-Owner Company
Your salary figure comes from the reasonable salary guide, not from whatever is left in the account at month-end. Pay yourself at least as often as your state’s minimum, and pick a schedule you’ll actually keep.
What Your First Owner Payroll Triggers
Your first owner paycheck starts these obligations at once:
- Deposits: the federal withholding and payroll taxes on your salary start going to the IRS, on the monthly schedule at first; the schedule can change each year, and right away if taxes reach $100,000 during a deposit period.
- Quarterly filings: Form 941 is due for the first quarter you’re paid and every quarter after it.
- Annual filings: Form 940 and your W-2 are due each January.
- State accounts: state withholding deposits start with that first check, and state unemployment returns start once you’re registered.
Who Should Do Your Payroll?
A full-service provider should run your payroll. Anything less leaves too much risk in your lap, and the IRS still holds you responsible no matter who touches the buttons.
Imagine an owner who runs payroll alone and assumes withheld taxes go in once a quarter. By the time the IRS notices arrive, the bill is already over $1,000.
| Option | Best for | You still handle | Watch out for |
|---|---|---|---|
| DIY by hand, spreadsheet, or calculation-only software | No one; we advise against it | Deposits, filings, and year-end forms, plus the calculations if you do them by hand | The cheaper software plans only calculate pay and leave the tax work to you; errors and missed deadlines carry penalties |
| Payroll software (self-serve) on a full-service plan | Owners who are comfortable entering each payroll themselves | Running each payroll in the app: hours, changes, and approval | Confirm the plan deposits the taxes, files the returns, and watches for compliance changes such as a new deposit schedule on its own, not only when you report them |
| Full-service payroll provider | Owners who want someone else to run payroll for them | Sending hours and any pay-rate or staff changes | Confirm the provider watches for compliance changes such as a new deposit schedule on its own, and fixes its own errors |
| Accountant or CPA firm | Setup advice and setting the right salary for S-Corp owners, not running payroll | Approvals and data | Ask whether the firm runs payroll or refers it out; we refer it out |
Common Setup Mistakes That Cost New Employers Time and Penalties
Paying the First Employee Before Payroll Exists, Then Trying to Fix It Afterward
Wages paid before payroll is set up are still wages, so the withholding and payroll taxes on them were due on the normal schedule. Fixing it later means working out what should have been withheld, catching up the deposits, and correcting the filings, on top of doing the setup anyway.
Treating an Employee as a Contractor to Avoid Setup
A contract that calls someone a contractor doesn’t settle it; the whole working relationship does, under the test described above. Get it wrong and you can owe the employment taxes you didn’t withhold. If you qualify, the IRS’s Voluntary Classification Settlement Program lets you reclassify those workers as employees going forward for a payment of 10% of one year’s reduced liability. (irs.gov)
Missing State Registrations or the New-Hire Report
Your state withholding account has to be open before the first paycheck. A state unemployment account follows once your payroll crosses the state’s threshold; in Virginia, that’s $1,500 or more of payroll in a calendar quarter or an employee working in 20 or more weeks of a year. The new-hire report is due within 20 days of the hire date, or sooner if your state says so. (vec.virginia.gov)
Choosing a Pay Frequency the State or Cash Flow Cannot Support
Pick a pay frequency that meets your state’s minimum and that your cash can cover every payday. If weekly payroll would leave you short some weeks, run it biweekly, as long as biweekly meets your state’s rule.
Forgetting That the First Payroll Starts the Deposit and Filing Schedule
A new employer deposits monthly in its first calendar year, and if taxes reach $100,000 during a deposit period, they’re due the next business day and the employer moves to the semiweekly schedule. Form 941 then follows every quarter.
The annual returns start with that first payroll too. Imagine an owner whose software calculates paychecks but never files the annual Form 940. By the first IRS notice he’s three years behind, with penalties and interest for each year, and he has to ask the IRS to waive them with no guarantee it will.
Pre-Launch Payroll Checklist: What to Have Ready Before the First Paycheck
Have each of these in place before you run the first payroll:
- EIN issued
- State withholding account open
- State unemployment account open, once your state’s threshold applies
- Workers’ compensation coverage in force, if your state requires it
- Full-service payroll provider chosen and set up
- Pay frequency set
- Form W-4 requested (without one, default withholding applies), Form I-9 started, and state forms collected
- Direct deposit details entered
- New-hire report filed or on the calendar
- First deposit date and quarterly filing dates on the calendar
Conclusion
Four weeks of lead time lets the EIN, the state accounts, workers’ compensation, and provider setup land before your employee’s first day. Then put a full-service provider on the deposits and filings, and check its work.
Keep your own login to EFTPS and confirm that every deposit your provider reports actually shows up there, because the IRS still looks to you. (irs.gov)
FAQ: Setting Up Payroll for a Small Business
When Do I Need to Start Running Payroll?
You need payroll running before the first paycheck to an employee. For an S-Corp owner, payroll has to be running before your first salary payment.
Do I Need Payroll If I’m the Only Employee?
An S-Corp owner who works in the business needs payroll for their own salary, even with no other employees. A sole proprietor, a partner, or the owner of a single-member LLC taxed as a disregarded entity doesn’t.
How Long Does It Take to Set Up Payroll?
An EIN comes through immediately when you apply online. State accounts take longer, 10 to 14 days by mail in California, and provider setup can take from a day to about two weeks. Start four or more weeks before the first day to cover all three.
What Do I Need to Set Up the Payroll?
You need an EIN, a state withholding account, a state unemployment account once your state’s threshold applies, and workers’ compensation coverage if your state requires it. From each employee, collect a Form W-4, a Form I-9, any state withholding form, and direct deposit details. You also need a pay schedule that meets your state’s minimum.
When Is the Best Time to Switch Payroll Providers?
The first pay date of a new year is the best time to switch providers, because no year-to-date wages have to move. The start of a quarter is the next best. Mid-quarter is the worst, because the new provider needs the old provider’s records to file that quarter’s returns.
Can I Start Payroll in the Middle of the Year?
Yes, if you’ve never paid employees before, because there’s no history to carry over. Switching providers mid-year is different, because it means moving year-to-date wages into the new system.
Do I Have to Report a New Hire to the State?
Yes. Federal law sets a deadline of 20 days from the hire date, and a state can set a shorter one. Iowa uses 15 days. (law.cornell.edu)(legis.iowa.gov)
