Let's say a farmer in 1 harvest (3-4 month) earns $2000, he will remain tax free if not registered or he doesn't register it
You're from Indonesia right? That doesn't mean they're exempt from taxes, the law provides for that with some sanctions. It's just that sanctions aren't properly implemented, especially for the general public (non-civil servants).
For those who are trying to be registered as a taxpayer, they may have administrative interests where a tax card is one of the requirements.
And you must also be from Indonesia right? because you understand a little what I mean. As for the farmer's problem, so far there hasn't been any problem with the tax office and that's true. Even though their income can be said to have exceeded the minimum wage of employees. And from this difference between agency employees or government employees and farmers or freelancers, is this fair for the tax rules?
