[Summary]
Even small amounts of blog income may require tax verification. When you have multiple payment routes, such as advertising revenue, affiliate revenue, manuscript fees, etc., it is important to organize them.
In the office worker's side job blog, check the income by subtracting necessary expenses from sales. It is safer to not only check the 200,000 yen rule for income tax, but also to check resident tax.
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
In the office worker's side job blog, check the income by subtracting necessary expenses from sales. It is safer to not only check the 200,000 yen rule for income tax, but also to check resident tax.
| Check points | way of seeing |
|---|---|
| sales | Deposit amount for ASP, advertising distribution, article writing fee, etc. |
| expenses | Server fees, domain fees, interview fees, work tools, etc. |
| income | The amount after subtracting expenses from sales. |
| Caution | Don't force living expenses or hobby expenses into expenses. |
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
- Just look at the amount received and do not keep expense records.
- Confusing sales of 200,000 yen with income of 200,000 yen.
- Forgetting to check resident tax.
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 aggregated annual sales by ASP?
- Did you save evidence of server fees, etc.?
- Is your income over 200,000 yen?
- Have you checked the local government's resident tax declaration guidance?
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
While blogging income is easy to start small, as your income sources increase, it becomes difficult to tally it up. The best way to do this is to record your sales and expenses on a monthly basis.
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.
