Who Must File Form 5500?
Form 5500 (Annual Return/Report of Employee Benefit Plan) must be filed for most qualified retirement plans (401(k), profit-sharing, defined benefit, SIMPLE IRA, SEP-IRA) that cover at least one employee other than the owner and the owner's spouse. The filing requirement applies to both funded and unfunded plans.
Form 5500-EZ is a simplified version of Form 5500 for one-participant plans (plans that cover only the owner and the owner's spouse). Form 5500-EZ must be filed for solo 401(k) plans and solo defined benefit (cash balance) plans if the total plan assets exceed $250,000 at the end of the plan year. If total plan assets are $250,000 or less, no filing is required.
Practitioners should advise solo 401(k) and cash balance plan clients to track their plan assets carefully and begin filing Form 5500-EZ when total plan assets exceed $250,000. The failure to file Form 5500-EZ is subject to a penalty of $250 per day (up to a maximum of $150,000 per year). The IRS has a Delinquent Filer Voluntary Correction Program (DFVCP) that allows late filers to pay a reduced penalty.
Large Plan Audit Requirement
Plans with 100 or more participants at the beginning of the plan year are considered 'large plans' and must attach an independent qualified public accountant (IQPA) audit report to Form 5500. The audit must be performed by a CPA who is independent of the plan and the plan sponsor. The audit covers the plan's financial statements (statement of net assets available for benefits, statement of changes in net assets available for benefits) and tests for compliance with ERISA and the IRC.
Plans with 80–120 participants may be eligible for the '80-120 rule,' which allows a plan that was a small plan in the prior year to continue filing as a small plan (without an audit) if it has fewer than 120 participants at the beginning of the current plan year. Practitioners should advise plan sponsors who are approaching the 100-participant threshold to plan for the audit requirement.
EPCRS: Correcting Plan Errors
The IRS Employee Plans Compliance Resolution System (EPCRS) is a program that allows plan sponsors to correct qualified plan errors and avoid plan disqualification. EPCRS has three components: (1) the Self-Correction Program (SCP), which allows plan sponsors to correct certain plan failures without IRS involvement; (2) the Voluntary Correction Program (VCP), which allows plan sponsors to correct plan failures by submitting a VCP application to the IRS and paying a compliance fee; and (3) the Audit Closing Agreement Program (Audit CAP), which allows plan sponsors to correct plan failures discovered during an IRS audit.
Common plan errors that can be corrected under EPCRS include: excess contributions, missed required minimum distributions (RMDs), failure to include eligible employees in the plan, and failure to follow the plan document. Practitioners should advise plan sponsors to review their plan documents and operations annually to identify and correct any errors before they are discovered in an IRS audit.
Late Filing Penalties and DFVCP
The penalty for late filing of Form 5500 is $250 per day (up to a maximum of $150,000 per plan year). The IRS Delinquent Filer Voluntary Correction Program (DFVCP) allows plan sponsors who have failed to file Form 5500 to come into compliance by filing the delinquent returns and paying a reduced penalty. The DFVCP penalty is $250 per day (up to $1,500 per plan year for small plans, or $2,500 per plan year for large plans), which is significantly less than the maximum penalty of $150,000 per plan year.
Frequently Asked Questions
Form 5500 must be filed for most qualified retirement plans (401(k), profit-sharing, defined benefit) that cover at least one employee other than the owner and the owner's spouse. Solo plans (owner only) with assets over $250,000 must file Form 5500-EZ.
Form 5500-EZ is a simplified version of Form 5500 for one-participant plans (solo 401(k) and solo defined benefit plans). It must be filed if total plan assets exceed $250,000 at the end of the plan year.
Form 5500 is due 7 months after the end of the plan year. For calendar-year plans, this is July 31. An automatic 2.5-month extension is available by filing Form 5558.
Plans with 100 or more participants at the beginning of the plan year must attach an independent qualified public accountant (IQPA) audit report to Form 5500.
The IRS Employee Plans Compliance Resolution System (EPCRS) is a program that allows plan sponsors to correct qualified plan errors and avoid plan disqualification. EPCRS has three components: the Self-Correction Program (SCP), the Voluntary Correction Program (VCP), and the Audit Closing Agreement Program (Audit CAP).
More Tax Planning FAQs
What is the penalty for failing to file this form on time?
Failure-to-file penalties are generally 5% of unpaid tax per month (up to 25%). Failure-to-pay penalties are 0.5% per month (up to 25%). Interest accrues on unpaid tax at the federal short-term rate plus 3%. Penalties can be waived for reasonable cause (illness, natural disaster, IRS error). First-time penalty abatement is available for taxpayers with a clean compliance history.
What is the statute of limitations for IRS assessment related to this form?
The IRS generally has three years from the later of the return due date or filing date to assess additional tax. If the taxpayer omits more than 25% of gross income, the statute is extended to six years. There is no statute of limitations for fraudulent returns or failure to file. Taxpayers should retain tax records for at least seven years to cover the extended statute of limitations.
Can this form be filed electronically?
Most IRS forms can be filed electronically through IRS e-file or through tax preparation software. Electronic filing is faster, more accurate, and provides confirmation of receipt. Some forms (such as Form 2553 and Form 8832) must be filed on paper. The IRS mandates electronic filing for businesses that file 10 or more information returns (1099s, W-2s) starting in 2024.
What records should be retained to support this form?
Taxpayers should retain all records supporting the information reported on this form for at least seven years (to cover the extended statute of limitations for omission of income). Records include: receipts, invoices, bank statements, brokerage statements, contracts, and correspondence with the IRS. Electronic records are acceptable if they are accurate, complete, and accessible.
What is the first-time penalty abatement (FTA) program?
The IRS First-Time Penalty Abatement (FTA) program waives failure-to-file, failure-to-pay, and failure-to-deposit penalties for taxpayers who have a clean compliance history (no penalties in the three prior years, all required returns filed, and no outstanding tax debt). FTA is available by calling the IRS or submitting a written request. It is one of the easiest ways to get a penalty waived.
How does this form interact with state tax returns?
Federal tax forms often have state counterparts that must be filed separately. State tax laws do not always conform to federal tax law, so the state return may require different calculations or additional schedules. Taxpayers should review their state’s conformity to federal tax law changes and file all required state returns by the applicable deadlines.
What is the difference between a tax deduction and a tax credit?
A tax deduction reduces taxable income, saving taxes at the marginal rate. A tax credit directly reduces tax liability dollar-for-dollar. A $1,000 deduction saves $370 for a taxpayer in the 37% bracket; a $1,000 credit saves $1,000 regardless of the tax bracket. Refundable credits can reduce tax liability below zero, resulting in a refund. Non-refundable credits can only reduce tax liability to zero.
How does the alternative minimum tax (AMT) affect this form?
The AMT is a parallel tax system that disallows certain deductions and adds back preference items. Taxpayers who owe AMT must complete Form 6251 to calculate their AMT liability. Common AMT triggers include: ISO exercises, large state tax deductions, accelerated depreciation, and passive activity losses. Taxpayers should model both regular tax and AMT before making decisions that could trigger AMT.
How do I determine if my Solo 401(k) plan requires filing Form 5500 for 2026?
For 2026, a Solo 401(k) plan generally must file Form 5500-EZ if plan assets exceed $250,000 at the end of the plan year, per DOL regulations related to ERISA. If plan assets are below this threshold, filing is not required, which is common for many self-employed individuals. However, once plan assets surpass $250,000, filing Form 5500-EZ is mandatory to maintain compliance and avoid penalties.
What are the key steps to properly set up a Defined Benefit Plan alongside a Solo 401(k)?
To set up a Defined Benefit Plan alongside a Solo 401(k), first conduct an actuarial feasibility study to determine the appropriate benefit amount and funding requirements under IRC §412. Next, draft a plan document compliant with §401(a) standards and obtain IRS approval if necessary. Finally, coordinate contribution limits under §415(c) to avoid exceeding aggregate limits and ensure proper integration of both plans' funding obligations for 2026.
When must Form 5500-EZ be filed for a Solo 401(k) plan for the 2026 plan year?
Form 5500-EZ for a Solo 401(k) plan covering the 2026 plan year must be filed by the last day of the seventh month after the plan year ends, typically July 31, 2027, if the plan year aligns with the calendar year. Extensions may be requested using Form 5558, granting an additional 2.5 months, but failure to timely file risks penalties under ERISA enforcement. Accurate filing timelines are critical to avoid compliance risks.
What documentation should be maintained to substantiate Form 5500 filings for combined Solo 401(k) and Defined Benefit Plans?
Maintain detailed plan documents, actuarial valuations, contribution schedules, and participant census data supporting both the Solo 401(k) and Defined Benefit Plan. Per §6058 and DOL guidance, accurate records of plan assets, participant benefits, and funding status must be retained for at least six years. This documentation supports the accuracy of Form 5500 filings and defends against audit or examination triggers.
What triggers an audit or examination related to Form 5500 filings for small employer plans in 2026?
Triggers for audit include discrepancies between reported plan assets exceeding $250,000 without a Form 5500-EZ filing, inconsistent participant counts, and mismatches between IRS Form 5500 data and tax returns. Additionally, late filings, missing schedules, or failure to report required information under §6058 can raise red flags with the DOL or IRS. Proactive compliance minimizes risk of costly audits.
Can a taxpayer contribute to both a Solo 401(k) and a Defined Benefit Plan in 2026, and how do contribution limits interact?
Yes, a taxpayer can contribute to both plans concurrently; however, aggregate contribution limits under §415(c) must be observed. The Solo 401(k) allows up to $72,000 total contributions ($80,000 with catch-up for ages 60-63), while Defined Benefit Plan contributions depend on actuarial calculations but are subject to overall IRC limits. Coordination ensures total contributions do not exceed permitted maximums, optimizing tax benefits.
How should I explain to my client the differences between filing requirements and contribution limits for Solo 401(k) versus Defined Benefit Plans in 2026?
Explain that Solo 401(k) plans typically have simpler filing requirements, including no Form 5500 filing if assets remain under $250,000, and defined contribution limits under §402(g) and §415(c). In contrast, Defined Benefit Plans require annual actuarial valuations, mandatory Form 5500 filings regardless of asset size, and potentially much higher contribution limits based on projected benefits. Clarify that combining plans offers enhanced tax deferral but increases administrative complexity and compliance obligations.
