Why Japanese Property Gains Are Not Simply Sale Price Minus Purchase Price

The sale price itself is not the taxable profit

It is tempting to describe a property bought for JPY100 million and sold for JPY120 million as producing a JPY20 million taxable gain. Japanese tax calculations are more detailed. Acquisition cost and qualifying disposal expenses must be considered, which makes documentary evidence from both the original purchase and the eventual sale important.

Keep acquisition documents

Purchase agreements, receipts, brokerage documents, registration-related expense records, acquisition tax documentation and records of expenditure on the building or equipment may become important when determining acquisition cost years later. This does not mean that every payment made at purchase is automatically deductible. The tax treatment depends on the nature of each expense.

Land and buildings require different considerations

Land and buildings are not treated identically for all tax-calculation purposes. For a building, depreciation attributable to the ownership period can affect the acquisition cost used when calculating a subsequent gain. Buyers should therefore preserve documents showing not only the total transaction price but also, where available, the allocation between land and building.

Document selling expenses as well

Certain expenses directly required for the disposal, including qualifying brokerage expenses, may be relevant as disposal costs. Ordinary ownership and maintenance expenses are not automatically treated in the same way. Keep invoices and receipts together with a record explaining why each expense was incurred.

Non-resident sellers face an additional cash-flow issue

Where the seller is a Japanese tax non-resident, qualifying transactions can also involve 10.21% withholding from the consideration. The cash received at closing and the seller’s final tax liability should therefore be analyzed separately.

Practical conclusion

The best time to prepare for the tax consequences of a future sale is when the property is purchased. Maintain a permanent transaction file and obtain professional advice before disposal regarding acquisition cost, disposal expenses and any exemption or special rule applicable to the particular seller.
