A Complete Guide to Understanding POP Docs for Small Businesses
You've been offering pre-tax health insurance benefits to your employees for years. Every payday, you deduct their portion of health premiums before calculating taxes, helping them save money while reducing your payroll tax burden.
But there's one problem: If you don't have the right paperwork in place, the IRS could hit you with thousands in penalties. And worse, all those "pre-tax" benefits could suddenly become taxable income for your employees.
So what’s missing? A Premium-Only Plan (POP) document. While most business owners assume their payroll provider handles all the compliance details, the truth is that offering pre-tax benefits without proper documentation puts your business at serious risk.
In this guide, we'll explain exactly what a Section 125 Premium-Only Plan is, why you need it, and how to avoid costly penalties that could derail your business finances.
What Is a Premium-Only Plan Document?
A Premium-Only Plan document (POP Doc) is a written Section 125 cafeteria plan that legally allows employees to pay their portion of insurance premiums with pre-tax dollars. It’s the foundation that makes pre-tax benefit deductions legally compliant.
When your employees contribute to health, dental, vision, or other eligible insurance premiums through payroll deduction, those contributions can only be tax-free if you have a compliant POP Doc in place. Without it, every "pre-tax" deduction you've been processing is technically taxable income.
Key benefits of a POP plan include:
- Employee tax savings: Reduces federal, state, and FICA taxes on premium contributions
- Employer payroll tax savings: 7.65% reduction in FICA taxes for every pre-tax dollar contributed
- Increased take-home pay: Employees keep more of their earnings without increasing gross wages
- Simple administration: The most basic form of a Section 125 plan available
Understanding Section 125 Compliance Requirements
Section 125 of the Internal Revenue Code governs all cafeteria plans, including Premium-Only Plans. These regulations exist to ensure that pre-tax benefit programs don't unfairly favor highly compensated employees while providing genuine tax advantages to all participants.
Core Section 125 compliance requirements include:
- Written plan document outlining all terms and conditions
- Summary Plan Description (SPD) distributed to eligible employees
- Proper employee elections and enrollment procedures
- Annual nondiscrimination testing to ensure fairness
- Detailed record keeping for IRS audit purposes
The most critical requirement is that you have a written POP Doc before you begin offering any pre-tax benefit deductions. Many businesses operate for years without realizing they're missing this essential compliance piece.
Is a POP Doc Required for Your Business?
If you offer any pre-tax benefit deductions to employees, you must have a compliant Section 125 POP Doc. There are no exceptions.
Common scenarios requiring a POP document:
- Employees pay a portion of health insurance premiums pre-tax
- Dental or vision insurance contributions are deducted pre-tax
- Group life insurance premiums are paid with pre-tax dollars
- Any employer-sponsored insurance with employee contributions
What if you don't offer employee benefits? Well, you don't need a POP Doc. But the moment you start deducting any insurance premiums from employee paychecks on a pre-tax basis, Section 125 compliance becomes mandatory.
The confusion often arises because payroll providers automatically process deductions as "pre-tax" without verifying that proper documentation exists. They assume you have the required paperwork, but that responsibility actually falls entirely on you as the employer.
Penalties for Operating Without a POP Document
Operating a pre-tax benefit program without proper Section 125 documentation exposes your business to significant financial penalties and compliance risks.
Department of Labor (DOL) penalties:
- $100 per day for missing SPD
- Maximum $1,000 penalty if SPD isn't provided within 30 days of employee request
IRS penalties for willful violations:
- $110 per day for failure to distribute required plan information
- Fines up to $5,000 or imprisonment up to one year
- Fines up to $10,000 and/or imprisonment up to 5 years for false statements
- Plan disqualification resulting in all contributions becoming taxable income
The worst-case scenario? If the IRS disqualifies your plan, every "pre-tax" contribution your employees made could be reclassified as taxable income. This means amended W-2s, back taxes, interest, and penalties…and it could potentially affect multiple years of employee payroll.
Even beyond formal penalties, lacking proper documentation makes you vulnerable during IRS audits and creates liability if employees sue over inaccurate plan information.
Who Creates Premium-Only Plan Documents?
Third-party administrators (TPAs) specializing in employee benefits typically create Section 125 POP documents. These professionals understand the complex IRS requirements and can customize documentation to fit your specific business needs.
The TPA process typically includes:
- Benefit program review: Analyzing your current insurance offerings and contribution structures
- Plan design: Creating a compliant POP plan that meets your business objectives
- Document drafting: Writing the formal plan document with all required IRS provisions
- Ongoing administration: Providing compliance support, record keeping, and plan maintenance
What to look for in a TPA:
- Specialized expertise in Section 125 regulations
- Strong reputation and client references
- Comprehensive service offerings beyond just document creation
- Transparent pricing with no hidden fees
- Ongoing compliance support rather than one-time document delivery
Cost considerations: POP Doc services typically range from $100-$600 annually, though many payroll providers and HR outsourcing companies include this as part of their comprehensive service packages.

Take Action to Protect Your Business
Operating without proper Section 125 documentation isn't worth the risk. The potential penalties, back taxes, and compliance headaches far outweigh the cost of getting compliant.
If you're currently offering pre-tax benefits without a POP document:
- Stop processing pre-tax deductions until you have compliant documentation.
- Consult with a qualified benefits professional or TPA immediately.
- Review your payroll processes to ensure all deductions are properly documented.
- Consider working with a provider that includes compliance support in their services.
Remember, your payroll provider processes what you tell them to process. They can't make your benefit deductions legally compliant. Only proper Section 125 documentation can do that.
Don't wait for an IRS audit or employee complaint to discover you're missing critical compliance documents. Protect your business and your employees by ensuring your Premium-Only Plan is properly documented and legally compliant.
