First, the conclusion
Blue tax return is a system that allows you to receive benefits such as special deductions for blue tax return, provided that certain bookkeeping and notifications are completed. The procedure for filing a white return is relatively simple, but it does not have the same tax benefits as filing a blue return.
| Check points | way of seeing |
|---|---|
| Blue declaration | Requires prior approval application, bookkeeping, and financial statement preparation. There are benefits such as deductions. |
| white declaration | A declaration by a person who has not been approved for a blue return. There is an obligation to keep records. |
| person for | Consider blue if you have continuous business income and can manage it with accounting software. |
| Points to note | You need to check the filing deadline for the year you want to start filing your blue tax return. |
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 it is best to choose the blue tax return when filing the tax return.
- I don't think you need a ledger if you file a white tax return.
- If you don't create accounting rules while your side business is small, it will become unorganized later.
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.
- Do you plan to continue as a business?
- Have you checked the deadline for the blue tax return approval application form?
- Can you organize your books and receipts every month?
- Have you decided whether to use accounting software?
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
If your side job is temporary, a white tax return may be sufficient, but if you want to continue it, it will be easier later if you consider filing a blue tax return early. It will make a difference not only in the amount of tax, but also in the habit of keeping records.
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.
