Inside advice: You can, however, write off the cost of removing mold as a current business expense. That’s because a new IRS private letter ruling establishes a slightly different rationale for this type of environmental hazard. (IRS LR200607003)
As you know, your business can deduct “ordinary and necessary” expenses. That includes expenses for regular repairs that don’t prolong the property’s life or cause it to significantly appreciate in value. (You can’t deduct expenses for permanent improvements.)
The IRS case: One wing of a nursing home became mold-ridden due to excessive moisture. The owner removed the mold by tearing out most of the drywall and fixtures, then replaced the moldy drywall with new drywall of similar quality. The owner then painted the drywall and reinstalled the old fixtures.
Based on these facts, the IRS determined that the owner could deduct the mold-remediation expenses as ordinary and necessary business expenses. The IRS cited four reasons: the building use stayed the same, no structural alterations were made, the mold problem didn’t appear until after the owner bought the building and the work didn’t cause the building to appreciate in value or prolong its life.
Tip: While this private letter ruling technically can’t be cited as precedence, in the absence of more authoritative guidance, you’re on solid ground in claiming current deductions for mold removal if your circumstances are similar to those in the IRS movement.
