Is iDeCo Really Worth It?

— The “Exit Strategy” You Should Understand Before Joining —

iDeCo (Individual-type Defined Contribution Pension Plan) has been attracting attention as a system for building retirement savings.

Its advantages are widely known, such as:

  • “It provides tax savings”
  • “It helps prepare for retirement”

Indeed, iDeCo offers significant tax benefits.

However, there are also institutional restrictions and important points that are often overlooked.

In this article, we will summarize the key features of iDeCo.



The Biggest Advantage of iDeCo: Income Tax Deductions

The greatest feature of iDeCo is that:

  • Contributions are deductible from taxable income
  • Investment gains are tax-free

In other words, contributions can reduce income tax and resident tax, creating tax-saving benefits.

In particular, people with higher incomes tend to benefit more from these tax advantages.


On the Other Hand: “You Cannot Withdraw Until Age 60”

One of the most important aspects of iDeCo is that funds cannot be freely withdrawn midway.

As a general rule, you cannot access the money until the age of 60.

Because of this, some people later feel burdened by the fact that the funds are locked in, even if they initially joined for the tax benefits.

It is also necessary to consider:

  • Monthly management fees
  • Price fluctuations of investment products

Is There Taxation Even If You Lose Principal?

In iDeCo, the “receiving stage” is also very important.

There are several ways to receive the funds, including:

  • Lump-sum payment
  • Pension-style installments

Depending on the method chosen, the tax treatment may differ.

Furthermore, even if your investments result in a loss of principal, there are cases where taxes may still apply when receiving the funds.

In other words, it is important to think not only about:

“The tax-saving benefits when contributing”

but also about:

“How much money you will ultimately receive.”


The Ability to Continue Long-Term Is Essential

iDeCo is not a system designed for short-term results.

That is why it is important to consider in advance whether you can:

  • Continue contributing over the long term
  • Tolerate having your funds locked up
  • Accept fluctuations in principal value
  • Do you understand that, because the account cannot generally be closed midway, account management fees will continue to be charged even if you stop making contributions?

The Important Thing Is Not Simply “Following the System”

iDeCo is an excellent system, but it does not necessarily mean that:

“Everyone will always benefit from it.”

What matters is considering factors comprehensively, such as:

  • Tax-saving effects
  • Household financial situation
  • Future financial plans
  • Fees
  • Risk tolerance

Rather than starting with the system itself, it may be more important for long-term asset building to ask:

“Does this fit my lifestyle and financial goals?”

Furthermore, iDeCo has unique structural characteristics: once you enroll, you generally cannot cancel the plan midway. While you can stop your contributions, you must continue to pay the monthly administrative fees, and you cannot withdraw the assets you have accumulated until that point. Therefore, it is essential to fully understand the gravity of this commitment before joining.
