[Hometown Tax] What is my maximum amount? Calculation mechanism and safe upper limit simulation
Explaining the mechanism for calculating the ``maximum donation deduction amount (limit amount)'' that allows you to donate advantageously through hometown tax payments! We will introduce in detail how to calculate not only the annual income of salaried workers but also the income of self-employed business owners, the effect on the limit when using medical expense deductions and final tax returns, and how to use a simulator that allows you to safely calculate estimates without sending personal information externally.
1. I empathize with your concerns: I don't want to lose! Concerns about the “limit amount” of hometown tax payments
“I would like to receive an attractive return gift using my hometown tax, but I am not sure how much (limit amount) I can donate.”
"If you are a sole proprietor or freelancer, the calculation method is different from the annual income of a company employee, so it is difficult to know how to calculate it..."
I plan to file a tax return this year with medical expense deductions and mortgage deductions, but will these deductions lower the hometown tax payment limit?''
I looked for a simulator site to find out the limit, but I'm a little reluctant to send sensitive personal information such as my annual income and family composition online for calculation...''
Hometown tax payment is a very advantageous system that allows you to receive special products from various local governments for just 2,000 yen out of pocket. However, the maximum donation deduction amount (limit amount)'' in order to receive the maximum benefit varies from person to person.
There are many people who worry that they don't want to lose money, or that they don't want to do difficult calculations, or that they're afraid of sending personal information.

2. Explanation of the cause: How is the limit determined? How the calculation works
The maximum amount of donations that can be made under the 2,000 yen self-pay for hometown tax is determined by the amount of income tax and residence tax (income-based amount) you pay in that year.
The rough calculation logic is as follows.
1. Refund amount from income tax: (Donation amount - 2,000 yen) x income tax rate will be refunded.
2. Deduction from resident tax (basic portion): (Donation amount - 2,000 yen) x 10% will be deducted.
3. Deduction from resident tax (special portion): The amount that cannot be deducted in 1 and 2 above will be further deducted from resident tax. (However, this special portion has an upper limit of 20% of the income tax amount of the resident tax.'' The point at which this upper limit is reached becomes your limit amount.'')
Therefore, there are three main factors that determine the limit:
① Annual income/amount of income (difference between sole proprietorship and company employee)
- Company employee (salary earner): Calculated based on the "payment amount (annual face value stated on the withholding tax slip)". The higher the annual income, the higher the tax amount and the higher the tax limit.
- Sole proprietor (freelance): Calculated based on the
income amount'' obtained by subtracting expenses and various deductions (blue tax return special deduction, etc.) from sales, rather than the annual income (sales) itself. Please note that taxes are calculated based on take-home pay or profits.
② Family composition and various dependent deductions
If you have a large number of spouse deductions, dependent deductions (such as the number of children in high school or college age), or social insurance premium deductions, the amount of income to be taxed will be lower, so the limit on income will be lower than for single people.
③ Impact of other deductions (medical expense deduction, etc.) on final tax returns
In the year you pay hometown tax, if you also apply for Medical Expenses Deduction'' ** or Housing Loan Deduction (Special Deduction for Housing Loans, etc.)'' on your final tax return, the amount of resident tax and income tax you need to pay will be reduced. As a result, the "limit amount" that can be deducted for hometown tax payments will be lowered by several thousand yen to tens of thousands of yen (the limit amount will be lowered), so if you push the limit too much, you run the risk of increasing your out-of-pocket costs.
In this way, the limit amount is calculated based on very personal and detailed tax information (annual income, income, dependent status, other deductions, etc.).
If you use a simulator from a typical major portal site, there is a privacy concern that this sensitive annual income/income data will be sent to and collected by the portal site's server, which may cause you to receive a large amount of sales e-mail newsletters later.''**
