Top 9 Common Payroll Mistakes to Avoid in 2027

For small business owners who handle payroll themselves or oversee a small team, payroll mistakes are common, costly, and usually preventable. These mistakes are particularly serious because they can trigger heavy IRS fines, legal liability, and a severe loss of employee trust. If you will handle payroll in 2027, you need to be aware of common small business payroll issues and how to avoid them.

This article covers the most common payroll mistakes for 2027, along with guidance for avoiding each one.

9 Common Payroll Mistakes to Avoid

Employee compensation can be challenging for any business owner, and discovering a payroll discrepancy can be discouraging when you already have a long to-do list. Depending on the type and severity of your payroll mistakes, you might ask:

• How can I resolve a payroll discrepancy?

• How long does an employer have to fix a payroll error?

• What are the consequences of payroll errors?

Here are some common payroll mistakes anyone can make, along with tips for avoiding them.

1. Incorrect employee classification

When hiring for your business, it's essential to understand which classification to use - employee or independent contractor. One of the main differences between these classifications is the type of tax form they'll file for the wages you pay. An independent contractor should receive the appropriate 1099 tax form once their pay meets the reporting threshold, while an employee will receive a W-2.

The IRS states that an employer can be liable for taxes if it misclassifies an employee as a contractor. If you need help classifying a worker, the IRS provides guidance through common law rules. IRS common law rules test behavioral control, financial control, and the type of relationship between the worker and your business. Classification rules have been subject to regulatory change, so a current review with a professional is worth doing rather than assuming a past determination still holds.

2. Misunderstanding exempt and non-exempt status (and miscalculating overtime)

In addition to proper employee classification, you also need to confirm whether an employee is exempt or non-exempt. This exemption status refers to the federal FLSA, which sets requirements about minimum wages and overtime. As a small business owner, this means you must pay non-exempt employees minimum wage and overtime (time-and-a-half after 40 hours in a workweek under the FLSA). For more information on who should be exempt, review this Department of Labor Fact Sheet.

Violating the FLSA can lead to hefty fines, regulatory action, and even employee lawsuits, so it's essential to understand the difference between these two employee categories.

3. Disorganized records

Maintaining organized business records is essential. It helps you find documents quickly when you need them. Saving your documents in different locations and using inconsistent file names will only cause frustration and waste time. This is especially true for pay stubs and tax forms.

If you fail to keep organized records, this will complicate audits and investigations. Accurate records are one of your best defenses should the IRS ever have questions. When regulators request specific documents, you must comply. A simple way to avoid this mistake is to ensure an efficient organizational strategy. Keeping an organized database of employee documents can help prevent payroll issues and keep your business running smoothly.

Keep employment tax records for at least four years after filing the fourth-quarter return for the year. Keep records tied to COVID-era sick leave, family leave, and employee retention credit wages for six years.

4. Forgetting about remote and multi-state employees

Another common payroll mistake is forgetting that some employees may be in a different state. The number of remote employees has increased drastically over the past few years, creating new challenges for remote payroll and taxes. Hiring even one employee in a new state can trigger state payroll tax registration, unemployment insurance, and withholding obligations.

If you make this type of payroll error, the consequences will depend on local laws and regulations. Always know where your remote employees work by requesting relevant tax forms with their addresses. If your remote employees move around and work in different states, you may need additional incorporations, so it's best to work with a professional who can advise on next steps.

5. Mistake on paycheck

Some payroll mistakes may not be apparent right away, but an employee will notice an inaccurate paycheck immediately. A paycheck includes many details, such as pay rate, hours worked, and sick leave, which can change regularly so that the total amount may differ each pay period.

A mistake on a single paycheck might not cause disaster, but it's still important to strive for accuracy. Several approaches can make payroll more efficient and reduce the risk of errors, and one of the best strategies is outsourcing the task to a payroll professional.

6. Inconsistent pay periods

Pay periods vary by business location, but it's a good idea to set a regular payday so employees know what to expect. Most business owners will choose weekly or bi-weekly pay periods, though the exact payday doesn't necessarily have to fall on the same date. For example, some paydays will inevitably occur on weekends or holidays, so you might need to adjust a day or two.

Processing payroll sporadically throughout the month will cause sloppy records and unhappy employees. You may also need to comply with specific regulations. Establishing a consistent pay schedule and informing your employees is good practice.

7. Not using direct deposit

Some employees and small business owners still prefer paper checks. While direct deposit is a more convenient and secure payroll method, the decision ultimately rests with the employee. Employers cannot mandate direct deposit, but it remains the preferred method when possible. A small number of states set specific rules on which pay methods an employer must offer, so direct deposit generally cannot be the only option.

Not using direct deposit can lead to payroll discrepancies, especially with handwritten checks. Human error is always a risk with manual work, so automation helps ensure consistency.

8. Missing payroll tax deposit deadlines

Federal payroll taxes (income tax withholding, Social Security, and Medicare) must be deposited on an IRS-set schedule. The IRS applies a monthly or semi-weekly schedule based on your business’s total tax liability. Missing a deposit deadline can trigger a failure to deposit penalty that scales with how late the payment is, up to 15% of the unpaid amount.

A payroll provider or dedicated accountant can help confirm which deposit schedule applies to your operations and handle the payroll process for you, so deposits are always made on time.

9. Failing to report new hires

Federal law requires employers to report newly hired employees, including their name, address, Social Security number, and hire date, to a state new hire directory. Most states expect this within 20 days of the hire date, though some require faster reporting.

This requirement aids in child support enforcement and helps prevent improper unemployment insurance payments. Missing this step is an easy oversight that can lead to serious state penalties.

FAQs About Common Payroll Mistakes

Can a dedicated payroll team make mistakes?

Yes, even a dedicated payroll service team can make mistakes due to manual data entry, miscommunications, or human error. Complex tax laws and sudden changes in employee withholding statuses can also lead to accidental miscalculations. Automated payroll systems minimize these risks, but oversight and review remain essential. If your provider makes frequent payroll mistakes, consider switching.

How do you overcome common payroll errors?

You can overcome common errors by auditing payroll records, communicating transparently with affected workers, and swiftly adjusting pay. Modern payroll software and a compliance calendar help prevent future mistakes. Regularly double-checking data before final submission also catches discrepancies.

How long does an employer have to fix a payroll error?

There is no specific federal deadline to fix a payroll error, but employers should correct mistakes by the next scheduled pay period. State laws often dictate faster timelines or require immediate action for underpayments to avoid labor board complaints. Quick corrections help maintain employee trust and reduce potential legal liabilities.

What penalties can the IRS charge for payroll tax mistakes?

The IRS charges a failure to deposit penalty of up to 15%, depending on how late the payment is made. Additional penalties between 2% and 10% apply for inaccurate tax forms or calculation errors. Monthly return penalties of 0.5% can also accrue for late filings.

Do payroll mistakes affect W-2s or 1099s?

Yes, unresolved payroll errors directly impact year-end tax documents like Form W-2 for employees or Form 1099 for contractors. Employers must file corrected forms, such as Form W-2c, to reconcile the discrepancies with the IRS. Failing to correct these forms can trigger tax notices or audits for both the business and the worker.

What’s the deadline to report a new hire?

Employers must report a new hire to their state’s designated agency typically within 20 days of the employee's start date, though some states have tighter deadlines. Timely reporting helps state agencies enforce child support orders and track employment data. Check local tax authorities and state guidelines to ensure full compliance with specific reporting timeframes.
