The tax legislation passed in 2025 — commonly referred to as the "One Big Beautiful Bill" — introduced several payroll and tax changes that are now in effect for 2026. Some of these changes create new administrative complexity for small businesses. Others create genuine opportunities if you understand how to take advantage of them.
Here is a plain-language breakdown of what changed and what it means for your payroll, your employees, and your bottom line.
No tax on overtime — what it means for your payroll
One of the most discussed provisions of the 2025 tax law is the overtime tax deduction, which took effect for the 2025 tax year. Under this provision, employees can deduct qualifying overtime wages from their federal taxable income.
For employers, this does not change how you calculate or pay overtime — that is still governed by the Fair Labor Standards Act and applicable state laws. What it does change is the information employees need from you. The IRS requires overtime amounts to be reported in Box 14 of the W-2, and employees need accurate records of their qualifying overtime hours to claim the deduction.
If your payroll system is not configured to separately track and report overtime, that is something to address now. Errors in this area directly affect your employees' ability to claim a deduction they are legally entitled to, which creates friction and potential liability.
For businesses operating in multiple states, the complexity increases — some states calculate overtime differently and those differences affect both withholding and the deductible amount for state tax purposes.
Tips tax treatment changes
The 2025 law also introduced a deduction for tips income for qualifying employees. For businesses in hospitality, food service, and other tip-dependent industries, this changes how you communicate with employees about their total compensation and what needs to be tracked and reported.
Tips are still subject to payroll taxes at the time they are received. The deduction applies at the employee's individual tax return level. But accurate reporting of tip income on W-2s is essential for employees to claim the deduction correctly.
If your business has tipped employees and your payroll processes are manual or inconsistent, this is a year to get that cleaned up.
Dependent care benefits limits increased
Effective January 1, 2026, the annual pretax contribution limit for dependent care flexible spending accounts increased from $5,000 to $7,500 for joint filers. The employer deduction for child care expenses also expanded — employers can now deduct 40 percent of child care expenses up to $500,000, up from 25 percent up to $150,000.
This is a meaningful benefit enhancement for employees with young children — and a meaningful recruiting and retention tool for employers who offer it prominently.
If you offer a dependent care FSA, your plan documents and employee communications should be updated to reflect the new limit. Employees who were maxing out at $5,000 may not know they can now contribute more.
If you do not currently offer a dependent care FSA, this is a good time to consider it. The increased limits make it a more compelling benefit, and a PEO can help you add it to your benefit package without significant administrative overhead.
Multistate payroll complexity is increasing
The 2025 federal changes layer on top of an already complex patchwork of state-level changes. The combination creates real administrative burden — particularly for businesses with employees in multiple states.
Overtime calculations vary by state. Minimum wage rates changed in more than two dozen states on January 1, 2026. Exempt salary thresholds increased in California, Colorado, and others. Paid family leave contribution rates changed in several states. Each of these affects payroll configuration, withholding calculations, and reporting.
For a business running payroll in-house across multiple states, getting all of this right requires constant monitoring and frequent system updates. Missing one change — an updated exempt salary threshold in a state where you have two employees, for example — can create back pay liability that far exceeds the cost of getting help.
Retirement plan changes under SECURE Act 2.0
The SECURE Act 2.0, passed in 2022, continues to roll out provisions that affect small business retirement plans in 2025 and 2026. Employers with 10 or fewer employees and those that have been in business for fewer than three years have additional time to phase in auto-enrollment requirements for new 401(k) and 403(b) plans.
Catch-up contribution limits also changed for 2025 and 2026, with higher limits for employees aged 60 to 63. If you have older employees and offer a retirement plan, these provisions may matter to them — and communicating them proactively is a meaningful employee benefit moment.
What this means for how you run payroll
The common thread across all of these changes is that payroll in 2026 requires more precision, more configuration, and more ongoing monitoring than it did in prior years. The combination of the 2025 federal tax law changes and state-level employment law updates creates a compliance environment that is genuinely difficult to manage without dedicated HR and payroll expertise.
For small businesses managing payroll internally, the risk of misconfiguration is higher than most owners appreciate. Payroll errors compound — an incorrect overtime calculation in January generates a gap that widens through every subsequent payroll run, creates W-2 discrepancies at year end, and can trigger IRS or state agency scrutiny.
How a PEO handles this for you
A Professional Employer Organization processes payroll as the employer of record, filing taxes under their own EIN and taking on responsibility for accuracy and compliance across all applicable jurisdictions.
When the 2025 tax law changes took effect, a good PEO updated their payroll systems to separately track and report overtime wages, configured dependent care FSA limits to reflect the new $7,500 ceiling, updated withholding tables and exempt salary thresholds in every state, and briefed their client companies on what changed and why.
You did not have to monitor the IRS for guidance updates or figure out how Box 14 reporting changes affect your payroll vendor. That was handled.
For businesses currently running payroll in-house who are feeling the complexity of 2026's changes, this is worth thinking about seriously. The cost of a PEO is often offset in part by the administrative time it reclaims — and the penalty and back pay exposure it eliminates.
