While Poi-Katsu is simple, accumulating significant points triggers income tax obligations and requires tax filing (確定申告) under Japanese tax law. We break down the tax classifications of loyalty points.

How Points Are Classified for Taxes

Under the National Tax Agency, points fall into different categories:

• Temporary Income (一時所得): Points earned via credit card spending or general web shopping cashbacks.
• Miscellaneous Income (雑所得): Points earned as direct compensation for tasks (surveys, game testing, friend invites).

Thresholds for Filing a Tax Return

For Salaried Workers (Company Employees)

• If your side-hustle earnings (including Miscellaneous point incomes) exceed 200,000 JPY annually, you must file a tax return.
• Temporary Income has a special deduction limit of up to 500,000 JPY, so returns are not required below this threshold.

For Dependents (Housewives/Husbands and Students)

• If your total annual income (including points) exceeds the basic deduction of 480,000 JPY, you must file, and you may lose dependent tax status.

Proactive Record-Keeping

The taxable event occurs when you convert points into cash, vouchers, or digital currencies. Maintain a ledger of your point redemption histories to avoid auditing problems.
