Running a small business is a marathon, not a sprint. Between managing inventory, keeping customers happy, and trying to find five minutes to eat lunch, the administrative side of things can easily pile up. We all know how hard it can be to keep your head above water when the IRS starts sending notices about payroll discrepancies.
Payroll isn’t just about writing a check or hitting "send" on a direct deposit. It is a complex web of federal, state, and local regulations that change almost every year. In 2026, the stakes are higher than ever with increased scrutiny on worker classification and updated reporting thresholds. If you are handling your own payroll or using a "set it and forget it" service without oversight, you might be sitting on a tax time-bomb.
Here are the seven most common mistakes small businesses make with payroll and the technical steps you need to take to fix them.
1. Misclassifying Employees as Independent Contractors
This is the "Big One." The IRS and the Department of Labor (DOL) are obsessed with the distinction between a W-2 employee and a 1099 independent contractor. Why? Because when you hire a contractor, you don’t pay half of their Social Security and Medicare taxes (FICA), you don’t pay unemployment taxes (FUTA/SUTA), and you don’t provide benefits.
The Mistake: Labeling someone a contractor just because they work remotely or because "they want to be paid 1099."
The Technical Reality: The IRS uses a three-category test to determine status:
Behavioral Control: Does the business direct how the worker does the task?
Financial Control: Does the business control the business aspects of the worker’s job (e.g., providing tools, unreimbursed expenses)?
Type of Relationship: Are there written contracts or employee-type benefits?
How to Fix It: If you realize you’ve misclassified someone, don’t wait for an audit. You may need to file Form SS-8 to get an official determination or look into the Voluntary Classification Settlement Program (VCSP), which allows eligible taxpayers to reclassify their workers for future tax periods with partial relief from federal payroll taxes.
2. Failing to Track "Compensable Time" Correctly
The Fair Labor Standards Act (FLSA) is very strict about what counts as working hours. Many small business owners think they only have to pay for the time spent "on the clock" at a desk or job site.
The Mistake: Not paying for prep time, travel between job sites, or "off-the-clock" emails.
The Technical Reality: Under the FLSA, if an employee is "suffered or permitted" to work, they must be paid. This includes those five minutes they spent answering a client text at 9:00 PM. Additionally, for non-exempt employees, overtime must be calculated at 1.5 times the "regular rate of pay," which includes non-discretionary bonuses and commissions: not just their base hourly wage.
How to Fix It: Implement an automated time-tracking system that integrates directly with your payroll software. This eliminates manual entry errors and provides a digital paper trail if an employee ever disputes their hours. If you need help setting up these systems, check out our Tax & Bookkeeping Insights.
3. Missing Critical Tax Deposit Deadlines
The IRS does not play around when it comes to their money. Payroll taxes: specifically the federal income tax, Social Security, and Medicare you withhold from employees: are considered "trust fund taxes." This means you are holding that money in trust for the government.
The Mistake: Treating payroll tax funds as extra cash flow for the business and missing deposit windows.
The Technical Reality: Most small businesses are either Monthly or Semi-weekly depositors.
Monthly: Taxes on payments made during a month are due by the 15th day of the following month.
Semi-weekly: If your total taxes were more than $50,000 during the lookback period, you typically have to deposit within three business days of the pay date.
How to Fix It: Set a recurring calendar alert for the 15th of every month. Better yet, ensure your payroll service is bonded and guaranteed to make these deposits on your behalf. Failure to deposit can result in a Trust Fund Recovery Penalty, where the IRS can hold business owners personally liable for the unpaid taxes.
4. Neglecting State and Local Tax Reciprocity
If your business is based in San Marcos but you have an employee living over the state line (or even just in a different city with local income tax), you have entered a world of tax pain.
The Mistake: Only withholding taxes for the state where the business is physically located.
The Technical Reality: You are generally required to withhold taxes for the state where the work is performed. However, many states have "reciprocity agreements" that allow employees to pay taxes only to their state of residence. In 2026, with the rise of hybrid work, the "nexus" (the physical or economic presence that triggers tax obligations) has become much easier to trigger.
How to Fix It: Audit your employee addresses quarterly. Ensure you are registered with the Department of Revenue and the Unemployment Insurance agency in every state where you have employees. If this sounds overwhelming, we all know how hard it can be to keep up with 50 different sets of rules. You can find more about our specialized Accounting and Tax Services to help manage multi-state compliance.
5. Errors in Form 941 and Form 940 Filings
Every quarter, employers must file Form 941 (Employer's Quarterly Federal Tax Return) to report income taxes, Social Security tax, and Medicare tax withheld from employee wages.
The Mistake: Numbers on the quarterly 941s don't match the year-end W-2 totals.
The Technical Reality: The IRS uses automated systems to cross-reference your 941s with the W-2s sent to the Social Security Administration. If there is even a $1.00 discrepancy, you will likely receive a notice (Notice CP210 or similar).
Important 2026 Deadlines:
Q1 (Jan-Mar): Due April 30
Q2 (Apr-Jun): Due July 31
Q3 (Jul-Sep): Due October 31
Q4 (Oct-Dec): Due January 31 (following year)
How to Fix It: Perform a "941 to W-3 Reconciliation" at the end of every year before you hit "file" on your W-2s. This involves adding up all four quarters of 941 data and ensuring it matches the totals on your W-3 (the summary form for W-2s).
6. Improper Handling of Fringe Benefits
Not all compensation comes in a paycheck. Gym memberships, company cars, and even certain types of life insurance are considered "fringe benefits."
The Mistake: Giving employees "perks" without realizing they are taxable income.
The Technical Reality: According to IRS Publication 15-B (Employer's Tax Guide to Fringe Benefits), most perks are taxable unless specifically excluded (like de minimis meals or health insurance). If you provide a company car for personal use, that value must be calculated and added to the employee’s W-2 as "other compensation."
How to Fix It: Review your "benefits" list annually. If you are paying for an employee’s cell phone or health club membership, ensure the value is being properly imputed into their gross pay so taxes are withheld correctly. For a deep dive into what is deductible for the business versus taxable for the employee, see our Pricing and Services page.
7. Ignoring the "New" 1099-K and 1099-NEC Rules
For 2026, the reporting landscape has shifted significantly. While 1099s aren't strictly "payroll" for employees, they are part of your labor cost reporting.
The Mistake: Failing to collect Form W-9 from contractors before paying them.
The Technical Reality: If you pay a contractor more than $600 in a year, you must issue a Form 1099-NEC. However, with the new thresholds regarding 1099-K (payment apps like Venmo and PayPal), there is a lot of double-reporting happening. If you pay a contractor via credit card, you actually don't issue a 1099-NEC because the bank issues a 1099-K.
How to Fix It: Never send a payment to a new contractor until you have a signed Form W-9 on file. This prevents the "January Scramble" where you are chasing down former contractors for their Social Security numbers. If you are an S-Corp or Partnership, remember that your business tax deadline is March 15th, and you need your contractor totals finalized well before then to get an accurate return.

Texas Payroll Notes (San Marcos & Central Texas)
If you employ people in Texas—especially in and around the San Marcos business community—payroll still has a few state-specific “gotchas” worth planning for:
No Texas state income tax withholding (but don’t confuse that with “no state payroll rules”). Texas doesn’t require state income tax withholding, but you still have federal withholding, FICA, and federal unemployment (FUTA) to handle correctly.
Texas unemployment tax (TWC) still applies. Texas employers generally need to register with the Texas Workforce Commission (TWC), file required wage reports, and pay state unemployment tax (SUTA) when they have employees performing services in Texas. Rate notices, reporting frequency, and “new employer” rates can vary, so it’s important to confirm your account setup is correct.
New hire reporting is required. Texas employers must report newly hired (and rehired) employees to the state’s new hire reporting program within the required timeframe. Missing new hire reporting can create compliance issues and can complicate child support withholding orders.
Local hiring can create multi-jurisdiction complexity fast. San Marcos sits between Austin and San Antonio, and it’s common for small businesses to hire across nearby cities or county lines—or to use hybrid/remote workers. Even when Texas is your home base, expanding your workforce across state lines can trigger additional state withholding and unemployment registrations (and may create nexus and payroll tax exposure elsewhere).
If you’d like, ProTaxMasters can help you confirm your Texas payroll registrations, review your filing cadence, and set up a clean compliance process that’s scalable as your San Marcos-area team grows.
