Getting payroll right is one of the most important — and unforgiving — responsibilities a small business owner faces. Pay someone late or miscalculate a deduction and you’re looking at penalties from the IRS, unhappy employees, and potential legal exposure. Do it consistently and correctly, and you build trust with your team and stay on the right side of federal and state agencies.
This guide is built for small business owners, HR managers, and anyone running payroll for the first time in 2026. Whether you have two employees or twenty-two, the fundamentals are the same. We’ll walk through every step — from the paperwork you need before you start, to filing year-end tax forms — so nothing falls through the cracks.
What You Need Before Running Payroll
Before you process your first paycheck, make sure you have the following in place. Missing any one of these can delay payroll or create compliance problems down the line.
- Employer Identification Number (EIN) — Your federal tax ID, issued by the IRS. Required to report employment taxes. Apply free at IRS.gov.
- State tax ID — Most states require a separate state employer ID for withholding and unemployment taxes. Check your state’s department of revenue or labor website.
- W-4 forms from every employee — Employees complete Form W-4 to tell you how much federal income tax to withhold from their paychecks. Collect a new one when someone is hired, and whenever their withholding situation changes.
- I-9 verification — Federal law requires you to verify every employee’s identity and work authorization using Form I-9. Keep these on file for at least three years after hire or one year after termination, whichever is later.
- Bank account set up for direct deposit — Most employees expect direct deposit. You’ll need your business checking account details and, ideally, ACH payroll capability through your bank or payroll software.
- Payroll schedule decided — Choose how often you’ll pay employees: weekly, biweekly, semi-monthly, or monthly. Some states mandate a minimum pay frequency — confirm your state’s requirements before you decide.
You’ll also want a dedicated payroll process — whether that’s a spreadsheet, payroll software, or an outsourced provider. We’ll cover the tradeoffs in a later section.
How to Do Payroll — Step-by-Step
Here’s the complete payroll process from start to finish. Follow these steps every pay period to stay accurate and compliant.
- Classify your workers (employee vs. contractor)
Before anything else, determine whether each worker is a W-2 employee or a 1099 independent contractor. The IRS uses a behavioral, financial, and relationship test to make this determination. Misclassifying an employee as a contractor is a costly mistake — the IRS can assess back taxes, penalties, and interest. If in doubt, file Form SS-8 to request an IRS determination, or consult an employment attorney. - Gather employee information
For each employee, collect their full legal name, address, Social Security Number (SSN), W-4 withholding elections, pay rate (hourly or salary), and any voluntary deductions (health insurance, retirement contributions, etc.). Store this information securely — payroll data is sensitive. - Determine pay periods
Your pay period determines how often employees receive paychecks and how you structure your payroll calculations. The four most common options:
Weekly — 52 pay periods per year. Common in industries with hourly workers like construction and retail.
Biweekly — 26 pay periods per year. The most common choice for small businesses.
Semi-monthly — 24 pay periods per year, paid on fixed dates (e.g., the 1st and 15th).
Monthly — 12 pay periods per year. Simplest to manage, but less frequent pay can create cash flow issues for employees.
Check your state’s pay frequency requirements — some states require at least biweekly pay for certain employee types. - Calculate gross pay
Gross pay is the total amount earned before any deductions.
For salaried employees: Divide the annual salary by the number of pay periods. A $60,000/year salary paid biweekly = $2,307.69 per paycheck.
For hourly employees: Multiply the hourly rate by hours worked. Don’t forget overtime — under the Fair Labor Standards Act (FLSA), non-exempt employees must receive 1.5x their regular rate for hours worked over 40 in a workweek. Review the FLSA Overtime Rules Guide for full details on who qualifies and how to calculate it correctly. - Calculate payroll deductions
Deductions fall into two buckets: mandatory and voluntary.
Mandatory deductions:- Federal income tax — based on the employee’s W-4 and the IRS withholding tables (Publication 15-T)
- State income tax — varies by state; some states have no income tax
- Social Security — 6.2% of wages up to the 2026 wage base ($176,100)
- Medicare — 1.45% of all wages (plus 0.9% Additional Medicare Tax on earnings above $200,000)
Voluntary deductions (pre-tax or post-tax):- Health, dental, and vision insurance premiums
- 401(k) or other retirement plan contributions
- HSA or FSA contributions
- Life insurance premiums
- Wage garnishments (child support, student loans, etc.)
Pre-tax deductions (like 401k contributions and health premiums under a Section 125 plan) reduce the employee’s taxable income, which lowers the amount of tax withheld. - Calculate net pay
Net pay is what the employee actually takes home: Gross Pay − All Deductions = Net Pay.
Double-check your math every pay period. A single calculation error compounds quickly and is frustrating for employees to sort out after the fact. Payroll software handles this automatically — one of the strongest arguments for using it. - Pay employees
Distribute pay on the scheduled pay date via direct deposit or paper check. Direct deposit is faster, more secure, and preferred by most employees. If you use a payroll platform, direct deposit is typically initiated 2–4 business days before the pay date to allow for ACH processing — don’t miss this window or employees will get paid late.
Some states require that you provide employees with pay stubs showing gross pay, deductions, and net pay. Even where it’s not required, it’s good practice. - File and deposit payroll taxes
This is where many small business owners get into trouble. Federal payroll tax deposits must be made on time — and the IRS doesn’t give much grace.
Deposit schedules:- Monthly depositors — deposit taxes by the 15th of the following month
- Semi-weekly depositors — deposit within 2–3 business days of each payday, depending on the day of the week
Your deposit schedule is determined by your total tax liability in the lookback period (the 12-month period ending June 30 of the prior year). New employers start as monthly depositors.
Federal returns to file:- Form 941 — Quarterly payroll tax return (due April 30, July 31, Oct 31, Jan 31)
- Form 940 — Annual FUTA return (due January 31)
- State payroll returns — varies by state
- Maintain payroll records
Federal law requires you to keep payroll records for at least three years. State requirements may be longer. Records to retain include: employee W-4s, time and attendance records, gross wages, deductions, net pay, tax deposits, and copies of all filed returns.
Storing these securely — preferably digitally with backups — protects you in an audit and simplifies year-end reporting. - Prepare year-end forms
At the end of each calendar year, you’ll need to prepare and distribute:
W-2 forms — Sent to each W-2 employee by January 31. Shows total wages paid and taxes withheld for the year. You must also file Copy A with the Social Security Administration.
1099-NEC forms — Sent to each independent contractor you paid $600 or more during the year, also by January 31.
File W-2s electronically if you have 10 or more (as of the 2024 tax year, the IRS lowered the e-file threshold from 250). Use the IRS Business Services Online portal or your payroll software to submit.
Payroll Tax Rates for 2026
Here’s a quick reference for 2026 federal payroll tax rates. State rates vary — check your state’s department of labor or revenue website for current rates.
| Tax | Employee Rate | Employer Rate | Wage Base / Notes |
|---|---|---|---|
| Social Security (OASDI) | 6.2% | 6.2% | Up to $176,100 (2026 estimate) |
| Medicare (HI) | 1.45% | 1.45% | No wage base limit |
| Additional Medicare Tax | 0.9% | None | On wages over $200,000 |
| Federal Unemployment (FUTA) | None | 6.0% (up to 5.4% credit) | First $7,000 of wages per employee |
| State Unemployment (SUTA) | Varies by state | Varies by state | Rate depends on experience rating |
Note on FUTA: Most employers qualify for a 5.4% credit against the 6.0% FUTA rate, resulting in an effective rate of 0.6% — but only if you pay your state unemployment taxes on time. States with outstanding federal loans may have a reduced FUTA credit (credit reduction states) — the IRS publishes this list annually.
Common Payroll Mistakes to Avoid
Even experienced payroll administrators make these errors. Knowing what to watch for helps you catch issues before they become costly.
- Missing tax deposit deadlines. The IRS penalty for late deposits ranges from 2% to 15% depending on how late the deposit is. Set calendar reminders and automate deposits wherever possible.
- Misclassifying employees as contractors. As noted above, this triggers back taxes and penalties. When in doubt, classify as an employee.
- Calculating overtime incorrectly. Overtime must be based on the regular rate of pay — which includes certain non-discretionary bonuses and shift differentials, not just the base hourly wage. Get this wrong and you’re exposed to FLSA liability.
- Not updating W-4s. When an employee’s life situation changes (marriage, new dependent, second job), they should submit a new W-4. Outdated withholding leads to surprises at tax time — and unhappy employees.
- Failing to account for state-specific rules. Some states have their own withholding forms, additional payroll taxes, specific pay stub requirements, or unique overtime rules. Multi-state employers need to stay on top of each state where employees work.
- Ignoring garnishment orders. If you receive a wage garnishment order (for child support, tax levy, or student loans), you are legally required to comply. Ignoring it exposes you to liability.
- Poor recordkeeping. If you’re audited and can’t produce payroll records, the assumption is rarely in your favor. Keep organized, backed-up records for the required retention period.
Should You Do Payroll Yourself or Use Software?
For a solo founder paying one or two people, manual payroll with a spreadsheet is technically possible. For most small businesses with five or more employees, payroll software pays for itself in time saved and errors avoided.
Here’s an honest breakdown:
Manual Payroll
- Pros: No software cost. Full control over the process. Works for very small teams with simple pay structures.
- Cons: Time-consuming — calculating taxes, deductions, and net pay manually takes hours per pay period. High error risk. You’re solely responsible for knowing and following all federal and state rules. Scales poorly as your team grows.
Payroll Software
- Pros: Automates tax calculations and filings. Direct deposit built in. Handles W-2 and 1099 preparation. Keeps up with tax law changes automatically. Many platforms offer HR features alongside payroll. Audit trail built in.
- Cons: Monthly subscription cost (typically $40–$150/month + per-employee fees). Requires some setup time upfront. You still need to input hours and review each pay run — software isn’t entirely hands-off.
For most small business owners, the cost of payroll software is minor compared to the time it saves and the penalties it helps avoid. If you’re processing payroll for more than 3–4 employees, software is almost always the right call. Check out our full guide to what payroll software is and how it works.
