Filing taxes on AdMob revenue, for first-timers

Your app made a little money through AdMob and now there is a payment from Google sitting in your account. The tax part feels heavier than the build ever did. It is more manageable than it looks once you break it into steps.

1. Know what kind of income this is

AdMob pays you as a publisher for ads shown in your app. For an individual, this is income that needs to be reported. The amount, timing, and category determine how it is treated, so keep every payment statement Google gives you.

2. Keep records from day one

Save the monthly earnings reports from the AdMob dashboard and the actual deposit records from your bank. Matching "what Google said it paid" against "what landed in the account" is the single most useful thing you can do before any filing.

3. Decide when registration matters

Small, occasional income and steady, growing income are treated differently. As revenue becomes regular, business registration and the right reporting path start to matter. This is the point where a short conversation with a tax professional saves hours later.

4. File through the official channel

In Korea, reporting goes through Hometax. Use the official site rather than secondhand summaries, the rules and thresholds change, and the official source is the only one that is current.
