IRS intermediate sanctions for nonprofit executive compensation create a comparability data vacuum where small nonprofits cannot prove 'reasonableness' without expensive consultants

IRC Section 4958 imposes a 25% excise tax (first tier) and a 200% excise tax (second tier) on 'excess benefit transactions' where a nonprofit insider -- board member, CEO, CFO, or other 'disqualified person' -- receives compensation exceeding fair market value. To establish a 'rebuttable presumption of reasonableness,' the board must document reliance on comparable compensation data from similarly situated organizations. So what? Small and mid-size nonprofits operating in niche sectors or rural areas often cannot find comparable salary data because surveys from Guidestar, NTEN, or regional associations lack granularity for their specific geography, budget size, and mission type. So what? Without valid comparables, boards either underpay executives (losing talent to better-paying organizations) or approve compensation they cannot defend if challenged by the IRS. So what? Hiring a compensation consultant to produce a defensible comparability study costs $5,000-$25,000, a prohibitive expense for organizations with budgets under $1M. So what? Board members who approve compensation without adequate documentation face personal liability for excise taxes -- the 25% first-tier tax and potential 200% second-tier tax fall on the individual who received the excess benefit, not the organization. So what? The threat of personal liability chills board service, making it harder for small nonprofits to recruit qualified directors, which degrades governance quality across the sector. The structural root cause is that the IRS adopted a market-based 'reasonableness' standard for nonprofit compensation but did not create a public, freely accessible compensation database. The rebuttable presumption safe harbor requires reliance on 'appropriate comparability data,' but what counts as 'appropriate' is left to board judgment, creating legal uncertainty that only expensive professional advice can mitigate.
