TPR safe harbors: three provisions, different requirements

De minimis: review the item and accounting policy

The federal de minimis safe harbor generally uses a $2,500 per-invoice or per-item threshold for taxpayers without an applicable financial statement, and $5,000 for those with one. An applicable financial statement has a specific meaning; ordinary internal financial reports do not automatically qualify.

The expenditure must satisfy the applicable book-expensing policy and other requirements, and an annual election is generally needed. For taxpayers with an applicable financial statement, written accounting procedures are required. Land and inventory are among the exclusions.

• Identify the policy in effect at the beginning of the tax year.
• Keep invoices that substantiate separate item costs.
• Confirm the amounts were treated consistently in the books.
• Ask the CPA to check the timely original-return election.

Routine maintenance: document the expectation

For a building, the routine maintenance safe harbor considers whether qualifying recurring activities were reasonably expected to occur more than once during the ten-year period beginning when the relevant structure or system was placed in service. Nonbuilding property uses a different measurement period.

The expectation should be supported by the property’s facts, experience and maintenance information. Calling a major replacement “routine” does not settle qualification; exclusions and the actual scope still matter.

Small taxpayers: calculate the annual building total

This safe harbor generally requires average annual gross receipts of $10 million or less and an eligible building with unadjusted basis of $1 million or less. The annual amount paid for repairs, maintenance, improvements and similar activities must not exceed the lesser of $10,000 or 2% of the building’s unadjusted basis. Aggregation and special property rules also need review.

The calculation includes qualifying amounts otherwise covered by the de minimis and routine maintenance safe harbors. It is not a separate allowance to deduct the first $10,000 of a larger project. A qualifying election is made for the relevant building and tax year.

If a safe harbor does not apply

Return to the general repair-versus-improvement analysis. Prepare a list showing the provision considered, the facts supporting or preventing qualification, the filing action and unresolved questions. This lets your CPA assess the position without treating every failed safe-harbor item as automatically capital.
