[Summary]
The first thing beginner investors get confused about is the difference between a NISA account and a specified account. Both are in a securities account, but the tax treatment is quite different.
NISA is a system in which investment profits within the tax-exempt limit are tax-free. Although the specified account is a taxable account, it is an account that makes it easy to manage profits and losses because the securities company prepares an annual transaction report for you.
In this article, we will organize the points that beginners should check first in the order in which they are most likely to stumble in practice. Since taxes vary depending on individual circumstances, please confirm the final decision with an official or specialized contact such as the National Tax Agency, local government, tax office, or tax accountant.
First, the conclusion
NISA is a system in which investment profits within the tax-exempt limit are tax-free. Although the specified account is a taxable account, it is an account that makes it easy to manage profits and losses because the securities company prepares an annual transaction report for you.
| Check points | way of seeing |
|---|---|
| NISA | Investment profits are tax exempt. Losses cannot be added up. There is an upper limit to the tax exemption limit. |
| Specified account/withholding tax | Taxes are deducted at source and often do not require filing. |
| Specified account/No withholding tax | Declaration confirmation is required based on the annual transaction report. |
| General account | You may need to calculate your own profit and loss. |
The important thing when reading tax articles is not just memorizing the system name. It's about looking at your income, accounts, deductions, and reporting methods separately.
common misconceptions
- I think NISA is advantageous in terms of taxes even if you lose money.
- Do not check whether or not a specific account has withholding tax.
- The NISA limit is used up by short-term trading.
This is an area where it is easy to get confused just by reading the search article. In particular, "sales" and "income," "income tax" and "resident tax," and "NISA" and "taxable account" need to be treated as different things.
Order of actual checking
If you are confused, it will be easier to organize if you check them in the following order.
- Is NISA suitable for products you want to hold for a long time?
- Do I need a taxable account if I want to consider short-term trading and profit and loss aggregation?
- Have you confirmed the withholding tax classification of the specific account?
- Have you confirmed the dividend receiving method?
If it is still difficult to make a decision after looking at the above, it is safer not to leave it to your own judgment. Please check through official channels such as consultation with the tax office, the National Tax Agency's tax return preparation corner, and consultation with a tax accountant.
Summary
NISA and specified accounts are not always the correct answer. If you consider the strength of tax exemption and the ease of calculating profits and losses and managing them, it will be easier to use them properly.
While it's hard to get away with not knowing about taxes, there's no need to fear them too much if you sort them out early. When your income increases, when you start investing, or when you want to use deductions, it is most practical to prepare your records early rather than at the end of the year.
