Taxation of Aircraft Leasing

Statutory definition

“Where a domestic corporation enters into a lease transaction, its income for each business year, as lessor or lessee, shall be calculated as if the asset subject to the transaction (hereinafter ‘leased asset’ in this paragraph) were sold when delivered by the lessor to the lessee.”

Corporation Tax Act Article 64-2 requires a domestic corporation entering into a “lease transaction” to calculate income as if a sale occurred upon delivery. Even a rental-form contract is treated as a sale if it meets the Article's definition of a lease transaction. Income Tax Act Article 67-2 provides a similar rule for residents.

Is an aircraft lease automatically treated as a “lease” for tax purposes?

Tax treatment of an aircraft rental contract depends on whether it meets the “lease transaction” requirements of Corporation Tax Act Article 64-2. The Article covers asset leases, excluding land leases without ownership transfer and other leases prescribed by Cabinet Order, and sets two requirements: noncancelability during the lease term or equivalent conditions, and substantive enjoyment of economic benefits and bearing of costs by the lessee.

The Article also addresses sales conditional on leaseback from buyer to seller, limited to qualifying lease transactions. Where the asset type, circumstances leading to the sale and lease, and other factors show the series of transactions to be substantively lending, income is calculated as if no asset sale occurred and a monetary loan was made. Income calculation depends on the statutory requirements and circumstances, regardless of whether the contract is labeled a lease or sale.

Are losses from partnership investments automatically deductible?

Article 67-12 governs the extent to which corporations may deduct partnership business losses. Its definition of “partnership agreement” includes Civil Code partnerships, investment limited partnerships, and silent partnerships, etc. Where an investor is a “specified partner” or “specified beneficiary” and liability for partnership business or similar debts is limited to partnership property value or similar circumstances apply, the portion exceeding an amount calculated under Cabinet Order based on contribution value, etc. is nondeductible. In cases prescribed by Cabinet Order where no substantive loss is expected, the entire partnership or similar loss is nondeductible.

LLP investments are separately governed by Article 67-13. Where a corporate partner's partnership business loss prescribed by Cabinet Order exceeds an amount calculated under Cabinet Order based on contribution value, the excess is nondeductible. Both Articles also provide, for corporations filing final returns and other required documents, for deductions up to an amount prescribed by Cabinet Order out of profits.

What happens if an individual invests in the same arrangement?

For individuals, Article 41-4-2 applies only where partnership or trust income is classified as real estate income; the statutory basis for classification is beyond this article's scope. It deems prescribed partnership or trust real estate losses of specified partners or beneficiaries not to have arisen. Unlike Articles 67-12 and 67-13, it treats the loss itself as nonexistent. Its “partnership agreement” means Civil Code Article 667(1) agreements, investment limited partnership agreements under Article 3(1) of the relevant Act, and similar foreign agreements including those prescribed by Cabinet Order; unlike Article 67-12, it does not list silent partnership agreements, etc.

Points that require care in practice

  • The scope of “land leases without ownership transfer and other leases prescribed by Cabinet Order” must be checked in the relevant corporation tax Order provision.
  • For “cases prescribed by Cabinet Order” under Article 67-12, the nondeductible amount is the entire partnership or similar loss, rather than only the excess over the contribution-based amount. Those cases and calculation methods for each prescribed amount must be checked in the Order for Enforcement of the Act on Special Measures Concerning Taxation.
  • Whether a person is a “specified partner” depends on involvement in decisions on important property disposals or acquisitions or substantial borrowing, personal conduct of contract negotiations and similar matters, and whether the person is an “other partner prescribed by Cabinet Order.” The latter must be checked in the Special Measures Act's Enforcement Order.
