These rules affect a lot\u2014 tax obligations, employee benefit plans, and needed Form 5500 filings, to name a few. A misclassification can burden you with unexpected costs, IRS penalties, and compliance challenges, and since ownership structures often change, plan sponsors should regularly review business relationships to avoid potential risks.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Our guide breaks down controlled groups through a fictional case study, illustrating how specific ownership and control patterns can trigger group status.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Controlled Groups and Key Tests<\/h2>\n\n\n\n<p>Controlled groups exist when multiple companies share common ownership or control. There are three main types.&nbsp;<\/p>\n\n\n\n<p><strong>1. Parent-Subsidiary Controlled Groups<\/strong>: A controlled group exists when a parent company owns at least 80% of a subsidiary.\u00a0\u00a0<\/p>\n\n\n\n<p><strong>2.<\/strong> <strong>Brother-Sister Controlled Groups<\/strong>: In this group, five or fewer individuals must own at least 80% of each entity and have at least 50% identical ownership across businesses.\u00a0\u00a0<\/p>\n\n\n\n<p><strong>3. Combined Groups: <\/strong>This is a mix of parent-subsidiary and brother-sister groups, where one company has overlapping ownership in two related entities.\u00a0\u00a0<\/p>\n\n\n\n<p>If a business isn\u2019t a part of a controlled group, it may still be classified as an affiliated service group \u2014 and this can also change benefit plan compliance.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Case Study: The Consequences of Misidentifying a Controlled Group\u00a0<\/h2>\n\n\n\n<p>For over 25 years, the owners of Company Alpha, a successful children\u2019s clothing retailer, expanded their business interests. They launched a clothing manufacturing facility (Company Beta), a luxury hotel and spa (Company Kappa), and two restaurants (Companies Delta and Epsilon). Ownership was distributed among family members, with each individual holding shares across multiple companies. Some family members also worked across the businesses in various roles.&nbsp;<\/p>\n\n\n\n<p>Each company supported its own employee benefit plan, with different contribution levels, retirement plan structures, and health insurance offerings. Company Alpha\u2019s plan was the most generous, offering higher employer-matching contributions and broader healthcare options. The business owners and their plan administrator believed they were in full compliance with ERISA and tax regulations\u2014until an IRS audit revealed otherwise.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The IRS Findings and Financial Consequences\u00a0<\/h2>\n\n\n\n<p>During the audit of Company Alpha, the IRS found interwoven ownership structures and overlapping management responsibilities, ultimately determining that all five businesses formed a controlled group under ERISA rules.&nbsp;<\/p>\n\n\n\n<p>As a result &#8230;\u00a0<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The IRS mandated retroactive benefit inclusion, requiring all employees from the related entities to be covered under Company Alpha\u2019s generous benefit plan for past years.\u00a0<\/li>\n\n\n\n<li>The businesses were assessed fines and penalties for non-compliance with controlled group rules.\u00a0<\/li>\n\n\n\n<li>Employees who had previously received lower benefits had to be compensated retroactively, significantly increasing employment costs.\u00a0<\/li>\n\n\n\n<li>The companies had to revise their benefit plan structure to follow IRS and Department of Labor regulations moving forward.\u00a0<\/li>\n<\/ul>\n\n\n\n<p>This unexpected financial and administrative burden disrupted cash flow, strained business operations, and required extensive legal and compliance work to rectify the situation.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Could They Have Done Differently?\u00a0<\/h2>\n\n\n\n<p>Had the business owners and plan administrators conducted annual reviews of ownership structures and applied controlled group tests, they could have shown the issue early and adjusted their benefit plans accordingly. Collaborating with third-party advisors and legal professionals before expansion would have helped them avoid costly missteps.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Your Best Practices for Controlled Group Compliance\u00a0<\/h2>\n\n\n\n<p>Being in business, you know that business relationships evolve. That&#8217;s why it\u2019s essential for plan sponsors to regularly review ownership structures to figure out if it changes impact-controlled group status. When you conduct annual compliance reviews, you unearth shifts in ownership, stock attribution, or management that could affect a group classification. Given the complexity of ERISA regulations, collaborating with experienced advisors can help navigate these rules and reduce compliance risks. Overlooking controlled group requirements can result in costly penalties, retroactive benefit obligations, and legal challenges. Taking an initiative-taking approach to compliance helps you manage your benefit plans effectively and avoid unnecessary financial exposure.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How MGO Can Help\u00a0<\/h2>\n\n\n\n<p>Our <a href=\"https:\/\/www.mgocpa.com\/solution-industry\/employee-benefit-plan-audits\/\" target=\"_blank\" rel=\"noreferrer noopener\">employee benefit plan audits team<\/a> works with plan sponsors to find risks, improve governance, and meet reporting obligations under ERISA and IRS regulations.
