Understanding Tax Basics to Manage Your Finances Wisely
This is about a 3-minute read.
Understanding Taxes Is the First Step to Protecting Your Finances
Many people go through life without thinking deeply about taxes, treating them as amounts automatically deducted from their income. However, simply understanding how taxes work can open up opportunities to legally increase your take-home pay. Utilizing deduction systems in particular can make a difference of tens of thousands to hundreds of thousands of yen per year, depending on whether you know about them.
Taxes are often avoided as being too complicated, but grasping just the basics relevant to daily life is more than enough. Here, we organize the fundamental tax knowledge that salaried employees and freelancers should know.
Key Taxes You Should Know
Income Tax
Income tax is a national tax levied on individual income. Japan uses a progressive taxation system where the tax rate increases as income rises. Rates are divided into seven brackets ranging from 5% to 45%.
The important point is that the highest rate does not apply to all of your income. For example, if your taxable income is 5 million yen, the first 1.95 million yen is taxed at 5%, the next 1.35 million yen at 10%, and so on in stages.
Resident Tax
Resident tax is a local tax paid to your prefecture and municipality. The rate is a flat approximately 10% of income (4% prefectural tax plus 6% municipal tax). Since it is calculated based on the previous year's income, you may receive an unexpectedly large resident tax bill the year after changing jobs or retiring.
Consumption Tax
Consumption tax is an indirect tax charged when purchasing goods and services. The current rate is 10% (with a reduced rate of 8% for food and certain items). While it is the most familiar tax in daily life, the burden is far from trivial when you consider your total annual consumption.
Making Use of Deduction Systems
Income Deduction Basics
For instance, income deductions are systems that allow you to subtract certain amounts from your taxable income. The larger the deduction, the lower your taxable income, and consequently the lower your tax bill. Major income deductions include the basic deduction (480,000 yen), spouse deduction, dependent deduction, social insurance premium deduction, life insurance premium deduction, and medical expense deduction.
Medical Expense Deduction
If your annual medical expenses exceed 100,000 yen (or 5% of total income), the excess can be deducted from your income. Expenses for family members sharing the same household can be combined. Dental treatments, prescription medications, and transportation costs for hospital visits are also eligible, so be sure to keep all receipts. Books on tax fundamentals can help you understand the full picture of available deductions.
Furusato Nozei (Hometown Tax)
This system lets you receive return gifts in proportion to your donation amount with an effective out-of-pocket cost of just 2,000 yen. The portion of your donation exceeding 2,000 yen is deducted from your income tax and resident tax. The deduction limit varies by income and family composition, so check using a simulation website beforehand.
Key Points for Tax Filing
When Salaried Employees Need to File
Salaried employees typically have their taxes settled through year-end adjustment, but tax filing is required in certain cases: when claiming medical expense deductions, when side income exceeds 200,000 yen, for the first year of housing loan deductions, and when not using the one-stop exception for Furusato Nozei.
Using e-Tax
The National Tax Agency's e-Tax system allows you to file your tax return online from home. With a My Number card and smartphone, there is no need to visit the tax office. Simply follow the on-screen instructions to enter your information, and the tax amount is calculated automatically.
Tax Strategies for Freelancers and Side Workers
For freelancers and those with side income, recording business expenses is the key to tax savings. Expenditures necessary for your business, such as communication costs, transportation, books, and software, can be recorded as expenses to reduce taxable income. (Related books may also help)
Choosing blue-form filing (aoiro shinkoku) provides a special deduction of up to 650,000 yen. While bookkeeping is required, accounting software makes it manageable even without accounting knowledge. Practical guides on tax filing and tax savings are also worth consulting.
