Should the government tighten regulations on tax deductions claimed for historic building conservation easements?
The U.S. Tax Court has disallowed charitable contribution deductions claimed by partnerships for façade conservation easements. The court determined these easements failed to protect conservation purposes in perpetuity as required by tax law.
Why it matters
The ruling underscores the strict adherence required for charitable deductions, specifically regarding the proportionate share of extinguishment proceeds in conservation easements. Failure to comply with these statutory requirements can lead to the denial of substantial tax benefits.
The court found that deeds for historic office buildings failed to include the value of development restrictions in the required extinguishment-proceeds formula. This non-compliance violates the proportionate share standards under I.R.C. §170(h).
The players
U.S. Tax Court
This federal court specializes in adjudicating disputes between taxpayers and the Internal Revenue Service regarding federal income tax deficiencies.
Internal Revenue Service
The federal agency responsible for tax collection and the enforcement of the Internal Revenue Code throughout the United States.
The details
Partnerships owning historic office buildings had claimed large deductions based on appraisals that assumed the potential construction of residential towers. The court held that because the deeds restricting development did not properly account for these values, they failed the perpetuity requirement.

Market Dynamics
This ruling highlights the ongoing tension between aggressive tax planning through conservation easements and federal regulatory enforcement. It signals a continued effort by the Internal Revenue Service to tighten oversight on complex real estate tax deductions.
Taxpayers who utilize conservation easements for historic preservation must ensure their deeds strictly adhere to federal proportionate share formulas. Failure to satisfy these technical requirements can result in the loss of deductions and subsequent IRS adjustments to tax returns.
The takeaway
Taxpayers should consult with tax professionals to ensure all conservation easement documentation meets current statutory standards for perpetuity. Relying on aggressive appraisals that do not account for legal deed restrictions can lead to costly disallowances during an audit.
