Retirement Plan Design Challenges Facing Architecture and Design Firms
Architecture and design firms face a unique set of retirement plan design challenges that differ significantly from those of other professional services organizations. Unlike firms with stable, predictable compensation structures, these firms often operate with project-based revenue, fluctuating bonuses, and gradual ownership transitions.
Senior leaders typically prioritize maximizing retirement plan contributions, while junior staff compensation may vary widely from year to year. This combination introduces complexity in plan administration and can increase compliance and fiduciary risk if not carefully managed.
Project-Based Bonuses and Nondiscrimination Testing Volatility
One of the most significant challenges is the impact of variable compensation on annual nondiscrimination testing. When compensation includes project completion bonuses, profit-based distributions, or irregular incentives, testing outcomes become highly sensitive to both timing and compensation definitions.
If these compensation elements are not applied consistently, issues can arise quickly. Inconsistent inclusion or exclusion of bonuses may lead to ADP/ACP testing failures, creating unexpected corrective contributions or refunds to highly compensated employees (HCEs).
Proactive testing projections and clearly defined compensation structures are essential to reducing volatility, avoiding additional costs, and maintaining compliance.
Partner Buy-Ins and Ownership Transitions
Ownership transitions are another defining characteristic of architecture and design firms. Many firms regularly admit new partners or implement phased buy-in structures over time. While these transitions support long-term continuity, they can significantly impact retirement plan compliance.
Changes in ownership may affect HCE status, introduce controlled group considerations, and shift contribution allocation strategies. Without coordination between ownership planning and retirement plan design, firms may unintentionally create compliance gaps or inefficient outcomes.
As a best practice, any ownership change should be reviewed alongside retirement plan provisions to avoid regulatory issues and unnecessary costs.
Growth and the Transition to Required Audits
As firms grow, they may exceed 100 eligible plan participants—triggering the ERISA requirement for an independent retirement plan audit. This milestone represents a meaningful shift in administrative complexity.
At the audit stage, documentation and procedural discipline become critical. Auditors closely review how compensation is applied, how eligibility is tracked, the accuracy of testing, and whether plan amendments are adopted on time.
Firms without strong administrative processes in place may face increased scrutiny, higher costs, and potential compliance findings during their first audit.
Proper plan operations and plan design can also help avoid this necessity as long as possible.
The Bottom Line
Architecture and design firms benefit most from retirement plans that are intentionally aligned with their compensation structures and ownership models. This includes accommodating variable income, anticipating ownership changes, and conducting testing projections before year-end.
A a retirement plan isn't just a benefit for your employees. Just as important is working with a retirement plan administrator who understands these nuances. The right partner can help identify risks early, guide plan design decisions, and ensure ongoing compliance—allowing firms to minimize surprises, control costs, and better support both leadership and staff over the long term.
