The good news is that the process, while genuinely involved, is learnable. If you set things up correctly before your first paycheck goes out, ongoing payroll is manageable – whether you run it yourself or use a payroll service. Here's what you need to know before you pay anyone a cent.
Before You Pay: The Setup You Can't Skip
Paying an employee legally isn't just a matter of writing a check. Several registrations and accounts need to be in place first, and trying to process payroll without them creates compliance gaps that are harder to resolve retroactively than to set up correctly the first time.
Obtain an Employer Identification Number (EIN). If you don't already have one, apply for an EIN through the IRS website – it's free and takes about 15 minutes online. Your EIN is the business equivalent of a Social Security number and is required for all federal tax filings, payroll tax accounts, and most state registrations. You can't run payroll legally without one.
Register with your state's tax and labor agencies. Federal taxes are only part of what you owe as an employer. Most states have their own income tax withholding requirements (some don't – more on that shortly), and every state with a payroll tax system requires you to register as an employer before you start withholding. You'll also need to register for state unemployment insurance (SUI), which is funded by employer contributions rather than employee withholding. The registration process varies by state but is typically done through your state's department of revenue and department of labor – often as separate registrations. Some states have combined these into a single employer registration portal. Find your state's requirements before your employee's first day.
Open a dedicated payroll bank account. This isn't legally required in most states, but it's strongly recommended. Keeping payroll funds separate from your operating account makes it dramatically easier to reconcile payroll, ensure tax deposits are funded, and track labor costs accurately. It also reduces the risk of accidentally spending payroll tax funds – a common and consequential mistake for first-time employers.
Understand What You're Actually Withholding and Paying
Payroll isn't just paying someone their wage. As an employer, you're responsible for withholding certain amounts from the employee's paycheck and for contributing additional employer-side taxes on top of their wages. Getting these numbers right is fundamental to legal compliance.
Federal income tax withholding is the amount you withhold from the employee's gross pay for federal income taxes. The exact amount depends on the employee's filing status and allowances, which they declare on their W-4 form. You must collect a completed W-4 from every new employee before or on their first day. The IRS Publication 15-T provides the withholding tables you use to calculate the correct amount, though payroll software handles this automatically if you use it.
FICA taxes – Social Security and Medicare – are split between the employer and employee. The employee pays 6.2% toward Social Security (up to the annual wage base) and 1.45% toward Medicare. You as the employer pay an identical match: 6.2% for Social Security and 1.45% for Medicare. This means FICA alone costs 15.3% of each employee's wages split evenly between you and them. You withhold the employee's share from their paycheck and pay both portions to the IRS.
Federal Unemployment Tax (FUTA) is employer-only – you don't withhold anything from the employee for this. The standard FUTA rate is 6% on the first $7,000 of each employee's wages, though you receive up to a 5.4% credit if you pay your state unemployment taxes on time, reducing the effective rate to 0.6%. For one employee earning more than $7,000 per year, FUTA amounts to about $42 in annual federal unemployment tax once the credit applies.
State income tax withholding applies in most states. Nine states currently have no state income tax – Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. In all other states, you'll withhold state income tax from employee paychecks at rates set by your state, again using tables your state provides or that payroll software incorporates automatically.
State unemployment insurance (SUI) is employer-funded and varies significantly by state and by your individual employer account rating over time. New employer rates typically range from 1% to 4% depending on the state, applied to the first $7,000–$40,000 of each employee's wages (the taxable wage base varies by state). You'll pay this quarterly to your state's unemployment agency.
The Employer's True Cost Per Employee
One of the most common surprises for first-time employers is discovering that the true cost of an employee is meaningfully higher than their stated wage. Before you agree to a compensation figure, calculate the fully loaded cost.
If you're paying an employee $20 per hour and they work 40 hours per week, their gross weekly wage is $800. On top of that, you're paying the employer's share of FICA (7.65% of their wages), FUTA, and SUI. At an average SUI rate of 2.7% and FUTA at its effective 0.6% rate, the employer-side payroll taxes alone add roughly $82–$85 per week to the cost of that employee – about 10–11% on top of their wage.
Add workers' compensation insurance (required in most states for any employee), any benefits you're offering, and any paid leave, and the true weekly cost of that $800-per-week employee is closer to $900–$950 in most situations. For small business budgeting, planning for employer costs of 110–115% of gross wages is a reasonable rule of thumb. In states with higher SUI rates, workers' comp rates for higher-risk industries, or where you're offering benefits, the multiplier is higher.
How and When to Deposit Payroll Taxes
Withholding money from employee paychecks creates a tax liability that must be deposited to the IRS on a specific schedule – and late deposits incur penalties. The IRS assigns every employer a deposit schedule based on your "lookback period" (the prior 12 months of employment tax liability). New employers are automatically assigned monthly depositors: you deposit payroll taxes by the 15th of the month following each payroll.
If you hire someone and run payroll in January, your first federal tax deposit is due February 15th. That deposit covers the federal income tax you withheld plus both sides of FICA for all payrolls run in January.
All federal payroll tax deposits are made electronically through the IRS's EFTPS (Electronic Federal Tax Payment System). You'll need to enroll at EFTPS.gov before making your first deposit. State tax deposits follow their own schedules, which vary by state and are typically quarterly for new employers with small payrolls.
Missing deposit deadlines carries a tiered penalty structure: 2% for deposits 1–5 days late, 5% for 6–15 days late, and 10% for deposits more than 15 days late. These percentages apply to the full deposit amount, which can add up quickly even on a small payroll. Setting calendar reminders for deposit deadlines is not optional if you're running payroll manually.
Payroll Software vs. Doing It Yourself
For most first-time employers with one or two employees, using payroll software is worth the monthly cost simply because the compliance burden of manual payroll is significant. The three most widely used options for small businesses are Gusto, QuickBooks Payroll, and ADP RUN.
Gusto is the most popular choice for small businesses with straightforward payroll needs. It handles federal and state tax calculations, automatic tax filing and deposits, direct deposit, W-2 generation at year-end, and new hire reporting. Pricing starts around $40 per month plus $6 per employee – for one employee, roughly $46–$50 per month. Gusto is particularly strong for businesses that want HR features like benefits administration alongside payroll.
QuickBooks Payroll is a natural fit if you're already using QuickBooks for accounting, since the integration eliminates manual reconciliation between payroll and books. Core payroll with tax filing starts around $45 per month plus $5 per employee. The integration with QuickBooks Accounting is the primary reason to choose it over Gusto; as a standalone payroll product for a new user, it's comparable in capability but slightly less intuitive.
Running payroll manually is possible if you're willing to track withholding tables, calculate taxes each pay period, set deposit reminders, file quarterly 941s (federal payroll tax returns) and annual 940s (FUTA), handle state filings separately, and generate W-2s at year-end. Some business owners prefer this level of control and find it manageable with one or two employees. The risk is that manual errors and missed deadlines are your responsibility, and the cumulative time cost is higher than most business owners estimate.
For a first employee, the $46–$50 per month that Gusto or QuickBooks Payroll costs is almost certainly worth it. The first time you file a quarterly 941 correctly or handle a year-end W-2 without a problem is a return on that investment.
Legal Requirements You Can't Overlook
Beyond taxes, several other legal requirements apply when you hire your first employee.
New hire reporting. Every state requires employers to report new hires to a state directory within a specified number of days (typically 20 days) of their hire date. This information is used to enforce child support orders and detect unemployment fraud. Most payroll software handles this automatically; if you're running payroll manually, you'll need to submit new hire reports through your state's reporting portal.
Eligibility verification. Federal law requires you to verify every new employee's identity and work authorization using Form I-9. You must complete this within three days of the employee's first day of work. Keep completed I-9 forms on file for at least three years from the hire date or one year after employment ends, whichever is later. I-9 audits do occur, and incomplete or missing forms result in fines.
Workers' compensation insurance. Most states require employers to carry workers' compensation coverage from the first employee. Requirements vary by state – a handful of states exempt very small employers or specific industries – but for most small businesses, workers' comp is legally required before the employee's first day. Premiums are based on your industry's risk classification and your payroll volume. Shop this through a commercial insurance broker or through your state's assigned risk pool if private market options are limited.
Posted notices. Federal and state labor laws require you to post specific notices in your workplace where employees can see them. Required federal posters cover minimum wage, OSHA rights, FMLA, and other employee protections. Most state labor departments provide required state notices. The Department of Labor's poster advisor tool at dol.gov helps you identify which posters are required for your specific business type and size.
Mistakes to Avoid
The most consequential mistake first-time employers make is misclassifying an employee as an independent contractor to avoid payroll taxes. The IRS and state agencies apply specific tests to determine worker classification, and businesses that misclassify employees face back taxes, interest, penalties, and sometimes employment law liability. If you control how, when, and where someone does their work, they're almost certainly an employee, not a contractor. When in doubt, a business attorney or CPA can help you classify workers correctly before any tax liability accumulates.
Missing quarterly 941 filing deadlines is the second most common compliance error. Federal payroll tax returns are due four times per year: April 30, July 31, October 31, and January 31. Failing to file on time, even if your deposits were made correctly, results in failure-to-file penalties. Calendar these dates before your first payroll run.
Underfunding payroll tax deposits by using withheld employee taxes to cover short-term cash flow needs is a serious error that many first-time employers make under pressure. The IRS treats withheld payroll taxes as trust fund taxes – meaning they're held in trust for employees and the government, not available as working capital. Misusing these funds can result in personal liability for business owners, piercing the corporate veil even in entities that would otherwise provide liability protection.
FAQ
Do I need to pay employees by check or can I pay by direct deposit? Direct deposit is not legally required in most states, but it's strongly preferred by employees and is included in every major payroll software platform. Some states prohibit employers from requiring direct deposit without the employee's consent, but most employees will actively prefer it. Paper checks require more handling, create more administrative work, and are slower for employees to access funds.
What's the difference between salary and hourly pay for a first employee? Beyond the obvious pay structure, the key difference is overtime eligibility. Hourly employees who are non-exempt under the Fair Labor Standards Act must be paid 1.5x their hourly rate for all hours worked beyond 40 in a workweek. Salaried employees may or may not be exempt from overtime depending on their salary level and job duties. The FLSA salary threshold for exemption is currently $684 per week ($35,568 annually). Pay careful attention to this if your employee's role may involve overtime hours.
When do I need to pay employees – is there a legal requirement? Yes. Most states have minimum pay frequency laws. Some require weekly payroll; others permit biweekly or semimonthly. Check your state's payday laws before setting a pay schedule. Changing pay frequency after the fact requires notice to employees and sometimes state notification.
Do I owe payroll taxes on employee tips? If your business receives tips, tip income is generally taxable wages subject to FICA and federal income tax withholding. Employees who receive more than $20 in tips per month are required to report them to you, and you as the employer must include reported tips in the payroll tax calculation. This is a specific compliance area where consulting a payroll professional or CPA familiar with your industry is worthwhile.
Get It Right From the First Paycheck
Payroll compliance is one of those things where the cost of doing it right upfront is far lower than the cost of fixing it after the fact. The registrations, the tax calculations, the deposit schedules, the quarterly filings – none of them are complicated once you understand the structure, but all of them carry consequences if they're ignored or rushed. Setting up a payroll service before your employee's first day, handling the registrations in the right order, and treating payroll taxes as untouchable funds from day one puts you in a position where running payroll becomes routine rather than stressful. That's the foundation your growing team deserves.
