Year-End Compliance: Wrapping Up & Planning Ahead 

For HR and benefits teams, December comes with two equally predictable things: holiday cheer…and year-end compliance. And while we’d all love nothing more than to settle comfortably into the food comas, twinkling lights, and festive chaos of the season, ACA reporting, data accuracy, and regulatory deadlines don’t take time off — no matter how heavy the snow falls. 

The good news? Getting ahead of your year-end compliance now can save you from the biggest post-holiday headache of all: starting the new year off behind. 

This guide walks you through the essential steps, key risks to avoid, and the resources available to help you wrap up 2025 smoothly — including our free Year-End Benefits Compliance Checklist 
  

Why Year-End Compliance Matters More Than You Think 

Even though Open Enrollment may be behind you, compliance remains front and center. December is your final chance to validate data, finalize ACA data for reporting, and tackle discrepancies before they snowball into costly issues in Q1. According to our Year-End Roadmap, staying ahead of compliance protects your organization from penalties, builds trust with employees, and positions your benefits program for success next year.  

Step 1: Audit and Reconcile Your Benefits Data 

Before you deck another hall or unwrap another peppermint truffle, it’s time for a full data audit. Our Ultimate Open Enrollment Roadmap lays out the must-do steps to close the year cleanly: reviewing employee information, verifying eligibility, and reconciling enrollment data.  

Here’s what needs to happen now: 

Confirm Employee Information 

• Names, SSNs, addresses 
• Eligibility classifications 
• Hire dates & status changes 

Reconcile Enrollment Data with Carriers 

• Ensure elections match BenAdmin platform + payroll 

• Clear discrepancy reports before they pile up 

Verify File Feed Timing 

• Ensure new plan year feeds are scheduled and correct 

It’s not the flashiest holiday task, but it’s the one that keeps January from becoming your personal nightmare before (and after) Christmas. 

Step 2: Finalize ACA Reporting Before Deadlines Hit 

Whether you’re sipping hot cocoa or trying to remember where you hid the last roll of wrapping paper, ACA deadlines are inching closer by the day. And the IRS? Not known for its festive flexibility. 

Accurate reporting relies on: 

• Correct eligibility determinations 
• Clean 1095-C and 1094-C data 
• Precise coding 
• Error-free TIN validation

Don’t leave this on your “after the holidays” list — that’s like waiting until December 24th to start gift shopping. 

Step 3: Conduct a Full Compliance Audit 

December is full of surprises (flight delays, last-minute shopping, relatives who show up unannounced), but your compliance shouldn’t be one of them. 

A thorough year-end audit means reviewing: 

Multi-State Compliance 

• Deduction rules 
• Mandated notices 
• State ACA filing requirements 

HIPAA & Data Security 

Keep your data as tightly protected as a gift hidden from the kids. 

Automation Tools 

Leverage automation wherever possible to reduce errors and simplify submissions. 
  

Step 4: Deliver Required Year-End Notices and Communications 

Employees may be drifting into vacation mode (or the fog of their third holiday potluck), but they still need timely benefits communications. 

Send: 

• Updated benefit summaries 
• Required notices 
• Renewal guides 
• Ability to make final changes before deadlines 

Clear year-end messaging reduces January confusion — and we’re all trying to avoid that, aren’t we? 

Step 5: Align Vendors, Payroll, and Internal Teams 

In the holiday spirit, think of this step as your version of coordinating a massive family dinner: everyone plays a part, and timing matters. 

• Verify vendors’ readiness for reporting 
• Sync benefits deductions with payroll 
• Review timelines across partners 
• Ensure your systems are aligned and accurate 

A smooth handoff now sets the tone for a frictionless new year.  

Step 6: Debrief & Plan for Next Year—Before the Ball Drops 

Before you officially close the books on the year, gather your team for a quick OE debrief. 

Ask: 

• What went well? 
• What broke? 
• What could be automated? 
• What do employees need more clarity on? 

Document those insights while they’re fresh — don’t wait until February, when the memory is as fuzzy as a post-party New Year’s Day. 

Then, begin setting compliance and OE goals that align with next year’s roadmap. Future-you will be grateful. 

Tools & Technology That Make Compliance Easier 

Efficient HR Teams prioritize the importance of smart technology all year long — but especially during year-end, when accuracy matters and deadlines will be here before you know it. 

This is where ACA software and partnerships make life infinitely easier for HR teams. Instead of wrestling with spreadsheets, reconciling data manually, or worrying whether your codes are correct, the right ACA software can automate the heavy lifting and help you stay confidently compliant.

Final Thoughts — Start the New Year on the Right Foot
