Ini panduan pengurusan perbelanjaan untuk mereka yang bekerja sepenuh masa sambil mempunyai kerja sampingan. Menuntut perbelanjaan dengan betul memberi faedah cukai, tetapi fahami juga perkara utama untuk mengekalkan privasi daripada majikan anda.

Ambang Pemfailan Cukai

Bagi penerima gaji, jika pendapatan sampingan melebihi ¥200,000/tahun, pemfailan cukai diperlukan. Namun, pemfailan cukai kediaman diperlukan walaupun di bawah ¥200,000.

Cara Merahsiakan Kerja Sampingan Anda

Avoid Competing with Main Job

Side jobs competing with your main job may violate regulations. Also avoid using main job information.

Understand the ¥200,000 RulePenting

Even if side income is under ¥200,000/year, residence tax filing is required. File with your local municipality even if income tax filing is not needed.

Soalan Lazim

The most common cause is residence tax. If you leave the payment method as "Special Collection (payroll deduction)" when filing, your employer receives notification of residence tax including side income, which payroll staff may notice. By selecting "Direct Payment (self payment)", you pay side income tax directly and it is not notified to your employer.
Income tax filing is not required, but residence tax filing is. If you neglect residence tax filing, you may face additional taxes later. Either file directly with your municipality, or file income tax return (which automatically files residence tax). Also, if you want medical expense or furusato deductions, income tax filing is required even under ¥200,000.
Yes, if you work on your side job at home, you can claim part of your rent as an expense. Calculate by floor area. For example, if using 6㎡ for work in a 30㎡ room, 20% of rent can be expensed. Keep records of your calculation basis.
It depends on the scale of your side job. If you have continuous income at a certain level (roughly ¥1M+ annually), Blue Return is beneficial. You get a ¥650,000 special deduction and can carry forward losses. However, it requires double-entry bookkeeping. For small side income, White Return is fine.
