Question 1

I'd like to know about filing tax returns.

Accepted Answer

If you are using a specified account with "withholding tax," the securities company will declare and pay the withheld tax amount, so in principle, you do not need to file a tax return. For those who need to file a tax return, please see below.

*For details on tax regulations, please consult your nearest tax office or tax accountant.

Question 2

I'd like to know about the average acquisition cost.

Accepted Answer

1. What is the Average Acquisition Price in a Specified Account?

The average acquisition price in a specified account refers to the average price of all shares purchased during the period leading up to the sale. It represents the average price per share and is the purchase price required for tax calculations.

2. How to Calculate the Average Acquisition Price in a Specified Account

The average acquisition price in a specified account is calculated using the following method:

1. Calculate the settlement amount (acquisition cost) each time a purchase is made and divide it by the number of shares held.

*However, for transactions made before the elimination of commissions, the calculation includes the commission in the acquisition price.

*If the same stock is purchased two or more times during the period leading up to the sale, the calculation is performed using a method similar to the "weighted average method."

2. If the same stock is bought and sold on the same day, the average acquisition price is calculated in the order of ① buy ② sell, regardless of the actual order of the transactions.

3. Calculations are rounded up to the nearest yen (decimal place).

Question 3

I would like to know about changes regarding whether or not withholding tax is applied.

Accepted Answer

Woodstock and AlpacaJapan Co., Ltd. only accept applications to change whether or not withholding tax is applied for the following year between December 1st and December 20th each year.

Regardless of whether or not you have transactions, you cannot change whether or not withholding tax is applied during the current year. You can apply for a change by going to the sidebar in the app, then to Account Information > Withholding Tax Settings, and clicking the "Change Withholding Tax Settings" button.

Question 4

I'd like to know more about specific accounts.

Accepted Answer

A specified account is a system established to reduce the tax burden on individual customers, and only one specified account can be opened at a single securities company.
When opening a specified account, you will choose either "withholding tax applied" or "no withholding tax (tax return required)."

At our company, transactions are generally conducted only through specified accounts.

(【Details of Specified Accounts】Table)
*If you wish to offset gains and losses with securities accounts opened at other companies, a separate tax return will be required regardless of whether withholding tax is applied or not.
