Get the definition wrong and the whole debate goes sideways
You see this all over social media:
National burden rate: 45.7%. Almost half of what you earn gets taken in taxes and social insurance premiums.
That's half right and half misleading.
According to Japan's Ministry of Finance, the national burden rate for fiscal 2026 is projected at 45.7%. It's the tax burden rate plus the social security burden rate added together, and it shows public burdens as a share of national income.
So it does not mean that 45.7% is deducted directly from an office worker's pay slip.
That part matters.
But that doesn't make the burden light, either. Not even close.
There's the share you can see on your pay slip. There's the employer's share, paid behind the scenes. And then there's consumption tax every time you spend money.
If you only judge by what's visible, you miss the full picture.
You pay a bit over 20%, and your employer quietly pays around 15%
For a salaried employee, the main things taken out of your pay are:
- Employees' pension (kosei nenkin)
- Health insurance
- Employment insurance
- Income tax
- Resident tax (a local tax)
The current employees' pension premium rate is 18.3%, split evenly between you and your employer. That's 9.15% for you and 9.15% for the company. Health insurance varies by which plan you're in and which prefecture you live in, but for Kyokai Kenpo (the national health insurance plan for employees of small and mid-sized companies), the fiscal 2026 medical portion averages around 9.90% nationwide, again basically split 50/50. Employment insurance in fiscal 2026, for general businesses, is 0.5% paid by the worker and 0.85% paid by the employer.
Roughly speaking, your social insurance premiums alone come to about 14 to 15%. Then income tax and resident tax go on top.
It depends on your income and whether you have dependents, but as an employee it feels like this:
Your share: a bit over 20% The employer's hidden share: around 15%
So if you ever thought,
"I pay about 20% as an employee, and the company pays another 10 to 20%?"
you're pretty close.
Of course, the exact numbers shift with your income, region, health insurance plan, age and dependents. But it isn't only you getting hit. The company shoulders a big chunk as labor cost, too.
That's the key point.
The employer's share also eats into room for raises
The social insurance premiums a company pays never show up on your pay slip.
But from the company's side, it's plain labor cost.
Say a company pays an employee a gross salary of 1 000 000 yen. The employee has taxes and premiums taken out of that. The company pays pension, health insurance, employment insurance, workers' accident insurance and so on on top of that 1 000 000 yen.
So from the company's point of view,
even if you think you're paying 1 000 000 yen gross, the real labor cost is around 1 150 000 yen.
That means when a company tries to raise pay:
- Gross salary goes up
- The employee's social insurance premiums go up
- The company's social insurance premiums go up
- Total labor cost goes up even more
And the company ends up thinking:
"I'd love to give raises, but labor costs are already heavy..."
The employee ends up thinking:
"My gross pay went up, so why is my take-home barely any higher?"
And then you spend your money and get hit with consumption tax too.
Taken from the front. Taken from behind. Taken again when you spend.
Your poor wallet is getting squeezed from three directions.
Social insurance premiums have gotten heavier than they used to be
Looking at the Ministry of Finance's historical figures, the national burden rate was 26.6% in fiscal 1976 and is projected at 45.7% for fiscal 2026. The social security burden rate in particular has climbed from 7.8% in fiscal 1976 to a projected 17.6% in fiscal 2026.
In short,
taxes are heavy, but the rise in social insurance premiums is the really big part.
That's exactly what working-age people feel in their bones.
You can't help wondering whether that money used to stay with companies and workers back then. Have salaries actually grown by that much since? Has everyday life become any more secure?
And that's where you go, "Hmm..."
