Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter E— Accounting Periods and Methods of Accounting › Part II— METHODS OF ACCOUNTING › Subpart C— Taxable Year for Which Deductions Taken › § 470
You cannot take a tax deduction in a year for a loss tied to property that is used by a tax-exempt group. If a loss is denied for a year, the denied amount is carried forward and can be treated as a deduction for that same property in the next year. Key terms: "tax-exempt use loss" — when the deductions tied to the property (including interest) are more than the income from it; "tax-exempt use property" — property treated as used by tax-exempt entities under the rules in section 168(h) with a few technical changes. Some leases are NOT subject to this rule. That includes leases where only a small amount of cash-like support is set aside (usually 20% of the lessor’s basis when the lease starts, with regs allowing up to 50% for very creditworthy lessees), leases where the lessor keeps at least 20% real equity at risk and the property is expected to be worth at least 20% at the end, leases where the lessee does not face meaningful loss risk under set tests, and certain long-life property leases with a purchase option. If property stops being tax-exempt use property, any carried-forward deduction for it can only be used up to the net income from that property each year, and leftover amounts keep carrying forward. Special rules apply if the whole interest is sold, for certain like-kind exchanges or involuntary conversions (including limits tied to leases entered before March 13, 2004), and related-party definitions and lender/loan rules are set out. The Treasury must write rules to handle grouping property under the same lease and how to split interest costs.
