First, the conclusion
To calculate taxes, first calculate income by subtracting necessary expenses from sales. Confirmation of income tax, resident tax, and in some cases social insurance and consumption tax is required for that income.
| Check points | way of seeing |
|---|---|
| Sales 1 million yen | Total deposit amount. |
| Expenses 200,000 yen | In this case, the income is 800,000 yen. |
| income tax | Combine this with other income, such as salary from your main job, to see the tax rate. |
| Resident tax | Affects municipal calculations. |
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 the sales of 1 million yen will be treated as taxable income.
- All tax funds are used up.
- We do not look at the relationship with the income tax rate of the main business.
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.
- Have you tallied your annual sales?
- Have you organized your expenses with evidence?
- Did you leave tax funds aside?
- Have you checked the resident tax and company regulations?
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
A side job of 1 million yen is a big plus for the household budget, but it also increases taxes and records. If you look ahead at how much money you'll have left over, you can avoid overspending.
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.
