The OBBBA Payroll Changes Are Here: What Every Employer Needs to Get Right in 2026

The One Big Beautiful Bill Act, signed into law on July 4, 2025, was widely covered as a tax reform package. Most of the headlines focused on the employee-facing benefits — no tax on tips, a new overtime compensation deduction, expanded child tax credits. What received far less attention was the operational burden the law placed on employers, particularly in payroll processing and reporting.

The 2025 transition year provided some breathing room. The IRS offered penalty relief for employers that hadn't fully updated their reporting, and the core W-2 and W-4 forms didn't change until the 2026 tax year. That transition period is now over. Starting with the 2026 tax year, the new reporting requirements are mandatory, and employers who haven't updated their payroll systems are accumulating compliance risk with every pay cycle.

Here's what employers need to understand and what your HCM or payroll system needs to be doing right now.

The Three Big Changes That Affect Payroll Operations

New W-2 Reporting Codes

The 2026 Form W-2 includes new Box 12 codes that employers are required to populate. Code TT reports total qualified overtime compensation — specifically the premium portion of FLSA overtime pay, not the total amount paid during overtime hours. Code TP reports total cash tips reported by the employee. And Code TA reports employer contributions to a new savings account established under the Act.

For many employers, Code TT is the most operationally significant. The IRS requires reporting of the overtime "premium" — meaning the additional half-time rate paid above the employee's regular rate, not the full time-and-a-half amount. Your payroll system needs to isolate this premium from total overtime earnings and track it cumulatively throughout the year, since the employee deduction is capped at $12,500 for individual filers.

This distinction matters because many payroll systems historically tracked overtime as a single earnings category. They calculated the full overtime amount — base rate plus premium — and reported it together. Now, the system needs to decompose that calculation and separately track the premium portion. If your system can't do this natively, your payroll team is either doing it manually or it isn't being done at all.

Updated W-4 Withholding Options

The 2026 Form W-4 has been revised to allow employees to adjust their federal income tax withholding based on anticipated deductions for qualified tips and overtime compensation. This means employees may submit updated W-4s requesting lower withholding, which your payroll system needs to process correctly.

The practical implication is that HR teams should communicate these changes to employees — particularly hourly workers who earn regular overtime or receive tips — so they can make informed decisions about their withholding. Employees who don't update their W-4 may over-withhold throughout the year and won't see the benefit of the new deductions until they file their tax return.

Expanded 1099 Reporting Thresholds

The OBBBA also raised the reporting threshold for Forms 1099-MISC and 1099-NEC from $600 to $2,000 for payments made starting in 2026. This reduces the number of information returns employers need to file for contractors and other non-employee payments, but it requires system updates to ensure the new thresholds are applied correctly.

It's important to note that the higher reporting threshold doesn't change the taxability of the income. All compensation remains taxable regardless of whether a 1099 is required. The change is purely a reporting simplification, but your payroll or accounts payable system needs to reflect the updated rules.

What Your Payroll System Should Be Doing Right Now

If your HCM or payroll vendor has implemented the OBBBA requirements correctly, you should be able to verify the following in your current system configuration.

Your payroll system should have separate earnings codes for FLSA overtime premium compensation, distinct from base overtime pay and regular earnings. It should be able to generate a report showing cumulative qualified overtime by employee, tracking toward the annual cap. If you have tipped employees, the system should have codes configured for qualified tip income and should be populating the appropriate W-2 Box 12 code.

Your W-4 processing should reflect the updated form, and your system should be applying the new withholding calculations correctly for employees who have submitted revised forms.

Your year-end processing configuration should be set up to produce W-2s with the new Box 12 codes populated. While year-end is months away, the data needs to be tracking correctly now — you can't retroactively reconstruct overtime premium data in December if it wasn't captured starting in January.

If you're unsure whether your system is configured correctly, ask your vendor directly. Request a test W-2 for an employee with overtime earnings and verify that Code TT is populated with the correct amount. This is a simple test that will tell you immediately whether the configuration is in place.

The Multi-State Complication

The OBBBA changes interact with state tax laws in ways that vary significantly by jurisdiction. Some states automatically conform to federal tax law and have adopted the new deductions. Others have chosen to decouple and require employees to add back the federal deductions on their state returns. And some states are still in the process of determining their approach.

For employers operating in multiple states, this creates a complex matrix of compliance requirements. Your payroll system needs to apply the correct treatment for each state — withholding at the federal level may reflect the new deductions, while state withholding may not, depending on the jurisdiction.

This is an area where your payroll vendor's compliance capabilities are tested in a very practical way. A vendor that has mapped the state conformity landscape and configured your system accordingly is saving you significant research and risk. A vendor that hasn't is leaving you exposed.

The Compliance Cost of Getting This Wrong

The IRS has been clear that the transition relief provided for 2025 does not extend to 2026. Employers who fail to separately report qualified overtime and tip income on 2026 W-2s face potential penalties for incorrect information returns. More importantly, employees who receive W-2s without the required codes may be unable to claim deductions they're entitled to — which creates employee relations problems on top of compliance exposure.

The penalty structure for information return errors has also increased in recent years. Late or inaccurate W-2 filings carry per-form penalties that escalate based on how long the error goes uncorrected. For an employer with hundreds of employees, these penalties can add up quickly.

Beyond the direct penalty risk, inaccurate payroll reporting can trigger broader scrutiny. The IRS is increasingly using automated cross-matching between employer filings and employee returns, and discrepancies are flagged for follow-up more quickly than in the past.

Steps Employers Should Take Now

If you haven't yet confirmed that your payroll system is fully configured for OBBBA compliance, here's a practical action list.

Contact your payroll vendor and specifically ask whether your system has been updated to support the 2026 W-2 reporting codes — TT for overtime, TP for tips, and TA for the new savings accounts. Don't accept a general assurance. Ask for documentation or a demo showing how the codes are configured in your specific instance.

Review your earnings codes to confirm that FLSA overtime premium is being tracked separately. If your system uses a single overtime earnings code that blends the base rate and premium, that code structure needs to change.

Communicate with employees about the new withholding options on the updated W-4. Employees who work regular overtime or receive tips should understand that they may benefit from adjusting their withholding.

If you operate in multiple states, confirm with your vendor that state-specific conformity or decoupling rules are reflected in your tax configuration. This is particularly important in states that have explicitly decoupled from the federal overtime or tip deductions.

And document your compliance efforts. In the event of an IRS inquiry, demonstrating that you took proactive steps to implement the new requirements — even if the implementation wasn't perfect — is significantly better than having no documentation at all.

The Bigger Picture

The OBBBA is the most significant payroll compliance change in several years, but it's part of a broader trend toward more granular employer reporting obligations. State paid family leave programs are expanding, each with their own withholding and reporting requirements. Pay transparency laws are multiplying across jurisdictions. And the IRS continues to modernize its enforcement capabilities, narrowing the margin for error in everything from tax filing to information returns.

For employers, the message is clear: your payroll system isn't just a tool for paying people. It's a compliance engine that needs to stay current with an increasingly complex and rapidly changing regulatory landscape. If your system — or your vendor — can't keep up, the cost of that gap shows up in penalties, employee frustration, and operational risk.
