Should You Contribute 6% to Your Labor Pension Even on a Salary Under $1 Million? A Real-Life Calculation Shows Some People Are Better Off Buying 0050

Contributing 6% of your salary to the labor retirement fund can build additional savings for retirement, but the reduction in monthly take-home pay leaves many young workers hesitant. Recently, a 28-year-old netizen posted online, saying their annual income hasn't yet reached 1 million yen and they're torn after elders repeatedly advised them to 'self-contribute 6% to accumulate a substantial retirement fund.' The post quickly sparked heated discussion.

The original poster (OP) shared on Threads that at age 28 with an income below 1 million yen, they're unsure whether they should 'self-contribute 6%.' They added that for someone with modest income like themselves, losing 6% of monthly pay is a noticeable burden. Yet, older relatives insist on self-contributing, saying the long-term accumulation of retirement funds can be significant. This dilemma prompted them to ask others in similar situations how they would decide.

The 'Self-Management & Investment' Camp: With Low Tax Rates, Better to Invest in ETFs

Many net users advised against mandatory self-contribution, suggesting that managing funds personally could yield higher returns. They emphasized the flexibility of accessing funds when needed, without being restricted by retirement age. Comments included: 'My university professor recommended self-contributing only if your income tax rate exceeds 20%; otherwise, just buy 0050 yourself,' 'Try calculating the difference between self-contributing and receiving dividends,' 'Skip self-contribution and invest in ETFs—you can withdraw funds whenever needed,' 'With personal dollar-cost averaging, you can immediately withdraw for emergencies or home purchases,' and 'Not being able to withdraw until age 60 is inconvenient, and who knows if withdrawal age requirements will change in the future?'

Others pointed out that the tax-saving advantage of 6% self-contribution benefits higher-income earners more. One user said, 'Self-contribution is mainly for tax savings, but you don’t pay much tax anyway,' while others noted, 'Tax savings only matter when income exceeds the threshold (e.g., over 1 million yen annually, entering higher tax brackets),' 'You don’t need to self-contribute until tax avoidance becomes necessary,' and 'Wait until your income tax bracket reaches 12% before starting self-contribution.'

The 'Forced Savings' Camp: Ideal for Those Lacking Discipline, a Dedicated Risk Hedge

Conversely, another group argued that self-contribution serves as forced savings, ideal for those lacking financial discipline to avoid spending impulsively. Users commented: 'Self-contribution is forced savings plus investment,' 'If you don’t self-contribute, you’ll just spend the money instead of investing it,' 'Retirement funds won’t become dramatically large, but this can serve as a risk-hedging channel,' 'First, ask yourself if you can consistently invest 6% monthly in 0050 until age 60–65,' and 'People who spend money like water must self-contribute (me?). Stocks or ETFs are too easy to cash out. At least protect that 6% as retirement savings.'

Some users with lower incomes or childcare responsibilities shared that they choose to contribute only 3% or 4%, maintaining a habit of forced saving without excessive burden.

Ministry of Labor Reminder: Workers’ Exclusive 'Guaranteed Returns' and Tax Benefits

The Ministry of Labor reminds that under the Labor Pension Act, employed workers, self-employed business owners who perform labor, and freelancers can voluntarily contribute up to 6% of their monthly wages or professional income to their retirement fund.

Self-contributing offers three key advantages:

- Tax benefits: Contribution amounts are fully deductible from annual gross income. - Guaranteed returns: Individual accounts receive guaranteed returns no lower than local banks’ 2-year fixed deposit rates. - Participation in fund earnings: Contributors participate in the labor pension fund’s returns. For example, the fund has achieved a 28.19% return so far this year, earning it nicknames like 'Worker’s ETF.'

Since financial strategies vary by individual, young workers should first calculate their income tax rate and financial capacity to assess whether this 'forced savings' retirement safety net is necessary for them.
