Absolute NNN vs. triple net lease depreciation does not turn on the marketing label. A lease may shift roof, structure, maintenance, insurance, and property-tax obligations to the tenant without resolving every question about which party can depreciate a particular asset. Buyers should connect the executed lease with the property conveyed and their independent advisers’ tax analysis.

This guide focuses on how lease clauses enter the depreciation review. For the broader eligibility framework, read Stonecliff’s net lease bonus depreciation guide.

Start with the contract, then map the assets

In brokerage usage, a triple net lease generally allocates taxes, insurance, and maintenance to the tenant. An absolute net arrangement may extend tenant obligations further, including significant structural work or replacement responsibilities. Terminology varies, so the actual provisions, exceptions, amendments, guaranties, and enforceability matter more than the listing description.

Build the investment model from those provisions. Identify who bears roof replacement, parking work, environmental obligations, casualty restoration, and expenses during a vacancy. Then give the same documents to tax and legal advisers so their ownership conclusions reflect the commercial agreement.

What the IRS says about leased property

IRS Publication 946 explains that a lessor can generally depreciate property it owns even when a tenant undertakes preservation, renewal, replacement, and maintenance. It also describes an exception involving an obligation to return the property or equivalent value in the same condition and value. Advisers should assess the complete arrangement rather than infer a result from a maintenance clause alone.

The publication discusses legal title, payment obligations, operating expenses, taxes, and exposure to loss among the incidents of ownership. These are considerations for professional review, not a checklist that automatically establishes tax ownership when a set number of boxes is checked.

A practical clause-to-question framework

• Maintenance and replacement: Does the tenant maintain existing landlord property, acquire new property, or fund an improvement? Keep acquisition and later expenditure records separate.
• Removal and surrender: Can equipment or trade fixtures be removed? What happens at expiration, default, casualty, or early termination?
• Casualty and condemnation: Who bears economic loss, controls restoration, and receives proceeds? Are there termination rights?
• Purchase options: Do options, financing terms, or other provisions warrant additional tax-ownership analysis?
• Third-party rights: Does a franchisor, equipment lessor, fuel supplier, or lender have ownership or security interests?

For a restaurant, compare the building and site with kitchen equipment and digital signage. For a fuel property, compare the real estate with tanks, dispensers, canopies, and supply agreements. These examples identify diligence questions; they do not assign tax lives or determine who owns an asset.

Where bonus depreciation enters the review

Once the buyer’s advisers establish ownership and basis, they can test each asset’s classification and eligibility. Land is not depreciable. The ordinary structural portion of commercial real estate generally remains 39-year property. Certain shorter-life assets may qualify for bonus depreciation when the applicable acquisition and placed-in-service requirements are met.

The lease does not convert the entire purchase price into an immediate deduction. A qualified cost-segregation analysis can help classify supported depreciable basis, while the investor’s tax professional evaluates elections and limitations. Review land allocation and placed-in-service timing as separate parts of that work.

Two illustrative lease comparisons

Same building, different expense clauses: Two buyers consider similar properties. One tenant handles ordinary maintenance; the other has broader replacement duties. Those clauses can materially change projected capital spending, but they do not alone establish different depreciation classes for the building.

Same lease label, different assets: Two offerings are both described as absolute NNN. One sale includes specified landlord equipment, while the other excludes tenant trade fixtures. The buyer’s depreciation review can differ because the conveyed assets differ, even though the marketing labels match. Neither example calculates a deduction or predicts a tax result.

Prepare a consistent adviser handoff

Provide the executed lease and amendments, purchase agreement, bills of sale, asset schedules, work letters, surrender provisions, title materials, relevant financing documents, improvement invoices, and available condition reports. Flag conflicts between the offering memorandum and the legal documents. Use the documentation checklist to organize unresolved questions.

Underwrite tenant credit, rent, location, capital exposure, financing, and exit independently. Any tax scenario should also address deduction usability, state treatment, adjusted basis, and potential recapture over the expected hold.
