Payroll Basics for First-Time Employers

Your first employee changes your relationship with the government. From the first paycheck you are collecting taxes on its behalf, and the penalties for getting that wrong are some of the harshest a small business can face. The good news: payroll is a repeatable process, and this guide walks through it in plain language.

Key takeaways

  • Payroll has four parts: registering as an employer, calculating pay and withholding, depositing taxes on schedule, and filing the returns.
  • The employer's own payroll taxes add a meaningful percentage on top of wages. Budget for them before you set a salary.
  • Payroll software or a provider is worth it from employee number one. The cost is small next to one late-deposit penalty.
  • Rules differ by country and by state. This guide uses US examples; check the rules where you operate.

Payroll feels intimidating because it mixes three things most owners have never done: tax withholding, government deposits and regulatory filings, each with its own deadlines. Break it into stages and it becomes routine. This guide covers the setup you do once, the cycle you repeat every pay period, the employer taxes you must budget for, and the mistakes that cost first-time employers the most. The examples use US federal rules. States add their own layers, and other countries have entirely different systems, so treat this as a map and confirm the details for your location.

Stage one: register before the first paycheck

Several registrations must be in place before you can legally pay anyone. In the US, the list typically looks like this:

  1. Get an Employer Identification Number (EIN). This is your business's federal tax ID, issued free by the IRS, usually within minutes online. You need it for every payroll filing.
  2. Register with your state. Most states require separate registration for state income tax withholding (if the state has an income tax) and for state unemployment insurance. Some cities and localities have their own payroll taxes as well.
  3. Set up workers' compensation insurance. Nearly every state requires it once you have employees, and the rules on who is covered vary. Your business insurance broker can usually arrange it.
  4. Collect the new-hire paperwork. Form W-4 tells you how much federal income tax to withhold. Form I-9 verifies the employee is eligible to work in the US and must be completed within three business days of the start date. Many states have their own withholding form.
  5. Report the new hire. Federal law requires employers to report new hires to their state's new-hire registry, generally within 20 days of the start date. Payroll providers often do this automatically.
  6. Choose a pay schedule. Weekly, biweekly, semimonthly or monthly. Some states restrict which schedules you can use for certain workers, so check before deciding.

Common mistake

Calling someone a contractor to avoid payroll. Whether a worker is an employee or an independent contractor depends on the facts of the relationship, not on what you call it or what the contract says. The IRS and labor agencies look at who controls the work, who provides the tools and whether the worker runs an independent business. Misclassification can lead to back taxes, penalties and claims for unpaid overtime and benefits.

Stage two: the pay-period cycle

Every pay period follows the same sequence. With software, most of this is automated once it is set up, but you should understand what the software is doing.

Calculate gross pay

For salaried staff, divide the annual salary by the number of pay periods. For hourly staff, multiply hours by rate, then add overtime. Under the federal Fair Labor Standards Act, non-exempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek. The federal minimum wage is $7.25 an hour, but many states and cities set higher minimums, and the higher rate applies. Some states also require daily overtime.

Subtract pre-tax deductions

Contributions to a traditional 401(k), health insurance premiums under a qualifying plan and similar items come out before taxes are calculated, which reduces the taxable wage.

Withhold employee taxes

  • Federal income tax: based on the employee's W-4 and IRS withholding tables. The amount varies with pay, filing status and the choices on the form.
  • Social Security: 6.2% of wages up to an annual wage base that the government adjusts each year (it was $176,100 for 2025).
  • Medicare: 1.45% of all wages, plus an additional 0.9% withheld from wages above $200,000 in a year.
  • State and local income tax: where applicable, based on state tables and forms.
  • Other withholdings: court-ordered garnishments, post-tax benefit contributions, union dues and so on.

Add employer taxes

These do not come out of the employee's pay. They are your cost on top of wages.

  • Social Security: you match the employee's 6.2%.
  • Medicare: you match the 1.45% (but not the additional 0.9%).
  • Federal unemployment (FUTA): 6.0% on the first $7,000 of each employee's wages, reduced by a credit of up to 5.4% for paying state unemployment tax on time, so most employers pay an effective 0.6%, or $42 per employee per year.
  • State unemployment (SUTA or SUI): a rate set by your state, applied to a state wage base. New employers get a standard rate that later changes based on your claims history.

Pay the employee and keep the records

Issue the net pay by direct deposit or check, provide a pay stub showing gross pay, each deduction and net pay (many states require this), and keep the payroll records. The IRS says to keep employment tax records for at least four years.

Worked example

Suppose you hire a salaried office manager at $48,000 a year, paid semimonthly, so gross pay is $2,000 per check. Imagine the W-4 and the IRS tables produce $160 of federal income tax withholding, and the state withholds $70. Social Security is $124 (6.2% of $2,000) and Medicare is $29 (1.45%). Total withholding is $383, so net pay is $1,617. On your side, you owe matching Social Security of $124 and Medicare of $29, plus FUTA on the first $7,000 of annual wages and state unemployment at your assigned rate, say 2.7% on a $9,000 state wage base in this example. Your payroll tax cost for this check is about $153 plus the unemployment taxes, and over a full year the employer taxes alone add roughly $4,000 to the $48,000 salary before benefits and workers' compensation. That is the number to budget, not the salary.

Stage three: deposit the taxes on schedule

This is where first-time employers get hurt. The money you withhold from employees is not yours; it is held in trust for the government, and you must deposit it along with your employer share on a fixed schedule.

In the US, federal income tax, Social Security and Medicare are deposited electronically through the Electronic Federal Tax Payment System (EFTPS). The IRS assigns you either a monthly or a semiweekly deposit schedule based on how much tax you reported in a prior "lookback period." New employers with modest payrolls typically start on the monthly schedule, with deposits due by the 15th of the following month. Very small employers whose annual liability is under a set threshold may be allowed to pay with their return instead. FUTA is deposited quarterly once the amount owed exceeds a threshold. States set their own deposit rules for withholding and unemployment.

Pro tip

Open a separate bank account just for payroll taxes and move the withheld and employer amounts there every pay run. The money is then visibly not available for anything else, and a deposit deadline never collides with a slow sales month.

Stage four: file the returns

Deposits pay the tax; returns report it. In the US, the main federal filings for most small employers are:

FormWhat it reportsWhen
Form 941Federal income tax withheld, Social Security and Medicare for the quarterQuarterly, by the last day of the month after the quarter ends
Form 940Federal unemployment tax for the yearAnnually, by January 31
Form W-2 and W-3Each employee's annual wages and withholding, and the summaryTo employees and the Social Security Administration by January 31
Form 1099-NECPayments of $600 or more to contractors (threshold is set by law and may change)To contractors and the IRS by January 31
State returnsState withholding and unemploymentVaries by state, often quarterly

Some very small employers may qualify to file Form 944 annually instead of quarterly 941s; the IRS tells you if that applies. Thresholds and forms change, so check the IRS and your state's current instructions each year.

Should you use software, a provider or do it by hand?

Manual payroll is possible with the IRS tables and a spreadsheet, but almost no one should do it. The arithmetic is easy; remembering every deposit date, rate change and form revision is not. Three options are common:

  • Payroll software: products such as Gusto, QuickBooks Payroll, ADP and Paychex calculate pay, withhold taxes, make deposits, file returns and produce W-2s. Most charge a monthly base fee plus a fee per employee. Plans and prices change, so compare current offerings.
  • Your accountant or bookkeeper: many offer payroll as a service, often running one of the products above on your behalf.
  • A professional employer organization (PEO): the PEO becomes the employer of record for tax purposes, handles payroll and benefits, and can offer group insurance rates. More expensive, more hands-off, and usually relevant once you have a handful of staff.

Why most first-time employers choose software

  • Automatic tax calculations, deposits and filings
  • Employee self-service for pay stubs and tax forms
  • Direct deposit included
  • Low monthly cost relative to penalty risk

What software does not do for you

  • Decide whether a worker is an employee or a contractor
  • Keep enough cash in the bank to cover the deposits
  • Track hours accurately unless you set that up
  • Know your state's leave, break and final-pay rules

Beyond the US

Other countries structure payroll very differently. The UK uses the PAYE system with real-time reporting to HMRC on or before each payday. Canada requires remittances to the CRA for income tax, pension and employment insurance. Australia has Single Touch Payroll and compulsory superannuation. Many European countries have high social contributions and mandatory payslip formats. The stages are the same everywhere: register, calculate, remit, report. The rates, forms and deadlines are not, so use a local provider or accountant from the first hire.

Mistakes that cost first-time employers the most

  • Late tax deposits. The IRS charges a failure-to-deposit penalty that rises with the number of days late, and trust fund taxes can be assessed personally against owners. This is the single most important deadline in your business.
  • Ignoring overtime. Salaried does not automatically mean exempt from overtime. Exemption depends on job duties and a minimum salary level set by regulation.
  • Skipping the I-9. It must be completed for every employee, including family members and part-timers, and kept on file.
  • Forgetting state and local rules. Paid sick leave, final paycheck timing, pay stub contents and pay frequency are all set at the state or city level in the US.
  • Not budgeting for the full cost. Wages plus employer taxes plus workers' compensation plus benefits. A rough rule many owners use is to add 10% to 20% on top of salary for taxes and insurance before benefits, but calculate your own figure.

First-hire payroll checklist

  • Obtain an EIN and register for state withholding and unemployment
  • Arrange workers' compensation insurance
  • Collect W-4, I-9 and state forms; report the new hire within the deadline
  • Choose a pay schedule allowed in your state
  • Set up payroll software or a provider and enter the employee
  • Open a separate account for payroll taxes and fund it every pay run
  • Put deposit and filing deadlines on your calendar, even if software handles them
  • Confirm the worker's employee or contractor status and overtime exemption with your accountant

Frequently asked questions

Can I pay myself through payroll?

It depends on your business structure. Owners of S corporations in the US generally must pay themselves a reasonable salary through payroll. Sole proprietors and partners usually take draws rather than wages. Ask your accountant, because the answer affects both taxes and retirement contributions.

What if I cannot afford the taxes one month?

Deposit the payroll taxes anyway and delay something else. Unpaid trust fund taxes carry severe penalties and can be collected from owners personally. If you are consistently short, the business cannot afford the employee at that wage, and it is better to face that early.

Do I need to run payroll for a part-time employee who works a few hours a week?

Yes. Employee status does not depend on hours. Part-time employees are subject to withholding, employer taxes and reporting like anyone else, although some benefit requirements are tied to hours.

How much time does payroll take each period?

With software and a salaried employee, a few minutes to review and approve. Hourly staff add the time to collect and check hours. The setup is the real work; the cycle is light once it runs.

The bottom line

Payroll is a set of fixed obligations on a fixed calendar: register, calculate, deposit, file. Use software or a provider from your first hire, keep the tax money separate, budget for the employer's share on top of wages, and confirm your state and country rules with a professional. Do that, and payroll becomes one of the most predictable parts of running your business.
