Leave Your Minpaku Property Management to the Experts
Free Online ConsultationIf you’re running a minpaku (private lodging) business, filing your annual tax return is an unavoidable part of the job. Minpaku income is subject to income tax, but whether it’s classified as “miscellaneous income” or “business income” makes a huge difference to your tax burden. Understanding how to properly handle minpaku expense deductions also allows you to file accurately while legally minimizing your tax bill.
In this article, we’ll walk through the criteria for classifying minpaku income, the types of expenses you can actually deduct and how to think about them, and key points to watch out for when filing—all practical information hosts can put to immediate use.
The Basics of Correctly Deducting Expenses on Your Minpaku Tax Return
Minpaku income is generally classified as either “miscellaneous income” or “business income.” Which category applies makes a major difference to your tax treatment—including whether you’re eligible for the blue-form tax return special deduction (up to ¥650,000) and whether you can offset losses against other income. Determining your income classification correctly is the essential first step toward an accurate filing.
As a general guideline, you’re required to file a tax return if your minpaku income minus necessary expenses exceeds ¥200,000 per year. This applies even to salaried employees—if you’re running minpaku as a side business, you still have a filing obligation. Even if your side income is ¥200,000 or less, you’ll still need to file a resident tax return, so don’t forget to handle both the tax office and your local municipal office.
Criteria for Distinguishing Miscellaneous Income from Business Income
For tax purposes, whether minpaku income falls under one category or the other is determined by comprehensively weighing factors such as “continuity and repetition,” “profit motive,” “social recognition,” and “scale of operation.” According to the National Tax Agency’s guidance, small-scale operations run as a side business tend to be classified as miscellaneous income, while continuous operations run as a primary business tend to be classified as business income.
As a rough benchmark, hosts with annual revenue of ¥3 million or less who don’t keep formal books are increasingly being classified under miscellaneous income. On the other hand, if you operate multiple properties, generate substantial annual revenue, and consistently maintain books and financial statements, you’re more likely to be recognized as having business income. When the classification isn’t clear-cut, consulting a tax accountant is the safest route.
Characteristics of Miscellaneous Income
Miscellaneous income applies to cases where annual revenue is relatively low and minpaku is run as a side business on a one-off or limited basis. You cannot apply the blue-form special deduction (up to ¥650,000 or ¥100,000), nor can you offset losses against other types of income. That said, only the “income amount”—revenue minus actual expenses incurred—is subject to tax, so deducting expenses properly still matters even under miscellaneous income.
For example, if your annual lodging revenue is ¥800,000 and your expenses total ¥500,000, your taxable miscellaneous income is ¥300,000. Miscellaneous income is reported on “Form 2” of your tax return and filed using the standard Tax Return Form A or Form B.
Characteristics of Business Income
If your operation is recognized as business income, choosing to file a blue-form return lets you claim the special deduction of up to ¥650,000. If you post a loss, you can also offset it against other income, such as salary, and carry forward losses for up to three years. This classification offers significant advantages for operators managing multiple properties with annual revenue in the millions of yen.
To file as business income under the blue-form system, you must submit a “Blue Return Approval Application” to the tax office in advance—within two months of starting your business, or by March 15 of the relevant tax year. Miss this deadline, and you won’t be eligible for blue-form filing that year. It’s also standard practice to submit a “Notification of Business Commencement” (sole proprietorship opening notification) at the same time.
Types of Deductible Expenses in Minpaku Operations and How to Think About Them
The basic rule for minpaku-related expenses is that they must be costs directly incurred for running the minpaku business. To avoid mixing personal spending with business costs, always keep receipts and itemized statements, and clearly document what each expense was for. Below, we’ll walk through the major expense categories in detail.
If you’re using part of your own home for minpaku, the concept of “apportionment” becomes important. You calculate the ratio of floor space used for minpaku relative to the total floor space, and only deduct that proportion of related costs. For example, if you use 30 square meters of a 90-square-meter home as minpaku space, roughly 33% of related expenses can be claimed.
Property Costs (Rent and Management Fees)
If you’re using a rental property for minpaku, rent, common area fees, and management fees can all be deducted as expenses. For a property used exclusively for minpaku, you can deduct the full amount; for a home used partly for personal living, you’ll need to apportion as described above. For example, if you use 50% of a property with ¥150,000 monthly rent for minpaku, that’s ¥75,000 per month, or ¥900,000 per year, in deductible expenses.
Note that when running minpaku out of a rental property, it’s essential that your lease agreement permits subletting or minpaku use. Operating in violation of your lease creates legal risk, so confirm with your landlord and clarify your contract terms before proceeding.
Utility Costs
Electricity, gas, and water costs incurred during guest stays are deductible expenses. For a property used exclusively for minpaku, you can deduct the full amount; for a shared home, you’ll apportion based on occupancy days or floor area ratio. For example, a property with average monthly utility costs of ¥20,000, operating at a 60% annual occupancy rate, would yield roughly ¥144,000 in deductible expenses per year.
Electricity costs in particular can vary significantly based on air conditioner usage, so installing a smart meter or IoT devices to visualize usage patterns can serve as supporting documentation for your apportionment calculations—and help you stay prepared in case of a tax audit.
Consumables (Amenities, Cleaning Supplies, etc.)
Amenities such as towels, shampoo, body soap, and toothbrushes, as well as cleaning supplies like toilet paper and detergent, can be fully deducted. For example, if amenity costs run ¥1,000 per stay and you operate 200 nights per year, that’s ¥200,000 in deductible consumables expenses.
Each time you make a purchase, note the purpose (minpaku use) on the receipt, or manage a dedicated purchase history for your minpaku business—this makes it easy to explain your records smoothly in the event of a tax audit. Online shopping purchase histories and order confirmation emails also serve as valid supporting documents.
Cleaning and Outsourcing Costs
If you hire a cleaning company or individual to clean after guest checkout, that cost is fully deductible. For example, if each cleaning session costs ¥5,000 and you have it done 200 times per year, that’s ¥1,000,000 in deductible outsourcing costs. It’s recommended to pay cleaning contractors via bank transfer or cashless payment methods so a clear record remains.
If you’re hiring an individual for cleaning and their annual compensation exceeds ¥500,000, you may be required to submit a payment record statement. Also, if payments to a specific individual occur on an ongoing basis, be careful about how you classify the payment—as “salary” or as “outsourcing expense”—since this distinction matters for tax purposes.
Platform Fees and Management Outsourcing Fees
Host fees paid to OTAs (online travel agencies) such as Airbnb or Booking.com can be fully deducted as costs necessary for conducting your business. Airbnb’s host fee is generally around 3% of revenue, though this varies by platform. For annual revenue of ¥2,000,000, that works out to roughly ¥60,000 in deductible fees.
If you outsource management to a minpaku property management company, those management fees are also fully deductible. Management fees typically range from 15–30% of revenue, so for annual revenue of ¥2,000,000, that’s ¥300,000–¥600,000 in deductible expenses—delivering a substantial tax-saving effect.
Depreciation Expenses
The purchase cost of a minpaku property, as well as investments in furniture, appliances, and equipment, are expensed through a method called “depreciation.” Assets worth ¥100,000 or more generally cannot be deducted in full in a single year; instead, a fixed amount is expensed each year according to the statutory useful life of the asset. For example, if you purchase a washing machine for ¥120,000 (useful life of 6 years, straight-line method), you can deduct ¥20,000 per year as depreciation expense.
Blue-form filers can take advantage of the “special provision for small depreciable assets,” which allows assets valued under ¥300,000 to be expensed in full in the year of purchase, up to an annual cap of ¥3,000,000. Taking advantage of this in your first year of operation—when initial investment tends to be high—can significantly reduce your tax burden.
Communication and Internet Costs
Wi-Fi provided for guests, as well as communication costs for the smartphone or PC you use to manage bookings and respond to guest messages, are deductible expenses. If the Wi-Fi line is dedicated solely to minpaku use, you can deduct the full amount. For a shared home line, apportion based on business-use percentage (e.g., 50%). For instance, apportioning 50% of a ¥6,000 monthly fiber-optic line comes to ¥36,000 per year in deductible expenses.
The purchase cost of a smartphone itself can also be deducted as depreciation, based on the percentage used for minpaku business. Monthly service charges are similarly apportioned by business-use ratio, so keeping clear records that separate business use from personal use will help substantiate your calculations.
Insurance Premiums
Premiums for liability insurance or contents insurance taken out for your minpaku operation are recognized as deductible expenses. Airbnb’s “AirCover” is a protection program, but many hosts also take out dedicated minpaku insurance separately, and those premiums are fully deductible. If your annual premium runs around ¥30,000–¥50,000, you can simply declare that amount as insurance expense.
If you’ve added a minpaku rider to your home’s fire insurance policy, only the portion of the premium attributable to that rider should be apportioned and deducted. The premium breakdown issued by your insurance company serves as supporting documentation, so be sure to keep these documents whenever your policy renews.
Expenses That May Not Be Recognized—and Key Points to Watch
Even when related to minpaku income, certain costs may not be recognized as deductible expenses for tax purposes. The most common issue is mixing personal consumption with business costs. For example, if you combine a personal trip with an inspection visit to your minpaku property, the travel costs are intertwined with personal travel expenses, making the basis for apportionment weak—and full deduction is unlikely to be accepted.
Similarly, some hosts try to deduct gifts for guests (souvenirs, sweets, etc.) as “entertainment expenses,” but since minpaku hospitality differs in nature from entertaining business associates, this carries a risk of being disallowed. It’s safer to keep such items within the scope of amenities or consumables. Additionally, the principal portion of mortgage repayments cannot be deducted (only the interest portion can be claimed, as either rent-equivalent expense or loan interest).
Bookkeeping and Preparing Your Tax Filing Documents
Accurate tax filing requires keeping daily records of income and expenses in a ledger. If you’re filing as business income under the blue-form system, double-entry bookkeeping is mandatory, and to qualify for the ¥650,000 deduction, you must file electronically via e-Tax or maintain electronic bookkeeping records. Even under miscellaneous income, you still need to keep income and expense records, preparing a “statement of income and expenses” that documents revenue, necessary expenses, and net income.
Useful accounting software for minpaku operators includes freee, Money Forward Cloud Tax Return, and Yayoi Online Accounting. All are available for roughly ¥1,000–¥3,000 per month and offer robust features for linking directly with OTA sales data. The filing deadline generally runs from February 16 to March 15 of the following year, but preparing early strengthens your ability to respond confidently should a tax audit arise.
