That New Tax Rule Might Cost You Money

The government is raising the 'income wall,' but it's a trap for anyone making near ¥1.3 million.

I saw someone online ask a question that made my blood run cold. They heard the government was raising the 'income wall' by ¥200,000, so they asked: "If I'm trying to stay under the ¥1.3 million wall now, does this mean I can earn up to ¥1.5 million next year and still be a dependent?"

No. Oh my god, no. It's an easy mistake to make, but it's a financially devastating one.

What's Actually Changing

So, the government is looking to raise the "¥1.03 million wall" to ¥1.23 million, probably from 2025. This is the number that matters for your *income tax*. If you earn less than this, you pay ¥0 in income tax, and if you're a dependent, your spouse gets a nice tax deduction.

This change is happening because they're increasing the Basic Deduction and Salary Income Deduction amounts. It's a purely tax-related move. That's it.

The Trap Everyone's Falling Into

The ¥1.3 million wall is a completely different beast. It has nothing to do with income tax. This wall is for *shakai hoken*—your mandatory health insurance and pension.

This wall is not changing. It is staying right where it is.

If you earn ¥1,299,999, you can stay on your spouse's health insurance for free. If you earn ¥1,300,000, you are legally required to enroll in your own plan. That means paying monthly premiums that can easily eat up ¥250,000 or more of your annual salary. Your take-home pay will actually go *down*.

So that person who thinks they can earn ¥1.5 million? They will suddenly find themselves with a much smaller paycheck than if they had just stayed under ¥1.3 million. It's a brutal lesson in Japanese bureaucracy.

So, What Are All These 'Walls'?

It's not just one wall. It's a whole maze designed to confuse you. Right now, you basically need to keep all these numbers in your head:

* **¥1.00 million:** You start paying resident tax.

* **¥1.03 million (soon ¥1.23M):** You start paying income tax.

* **¥1.06 million:** You might have to enroll in social insurance anyway, depending on your company's size and your hours. Yes, another trap.

* **¥1.30 million:** The big one. You're kicked off your spouse's social insurance.

* **¥1.50 million:** Your spouse's tax deduction starts getting smaller.

It feels like they want you to work more, but not *too* much more, you know?
