The company-type DC and the definitive contribution 、 are similar, but not the same range.

The final contribution is the name of the entire system.企業ing that, there is a company type DC introduced by the company, and an iDeCo that is enrolled individually.

In other words, corporate type DC is a type of definitive contribution. If you make a mistake, the company’s system, the individual system, the NA, the re。ement fee, and the DB will be mixed.

First Con まず

If you organize a relationship in a single word, it is:

Defined contribution = corporate type DC + iDeCo

Business type DC is a system to join if the workplace is introduced.

iDeCo is a system to select and join financial institutions.

Both of them are the same points that “operate by yourself and change the future payout depending on operational results.” What’s the difference is who makes a withdrawal, who chooses a financial institution or product line-up, and who pays a fee.

If you’re an employee, you’ll have a company-type DC to check it first.

If you have a company-type DC, check if you can use iDeCo next or how much your contribution limit is.

There is a difference in the company system. It is faster to see information about HR materials, corporate-type DCサイト sites and management agencies.

Difference between company-type DC and DB

The company's DB is well 。 as a corporate DB.

This two is quite different even if the name is similar.

DB is a system similar to "How much do you get in the future?"

How much is the company-type DC based?

If the re ement system transfers from DB to DC, some of the re ement funds that the company had entrusted will change to the money that you operate on your own. This is a big difference.

Difference between definitive contribution and NA

NA is a tax system for investment.

However, the usage is different.

If you don’t use the money until the old age, the final contribution is a strong system.

NA is more flexible if you have money that you might use on the way.

For example, if you put too much money in the final contribution, you will not be able to take any money that can be used for home purchases, educational expenses, independent funds, and jobの生活.

Which

Priority changes depending on household and work place system.

However, if you are a beginner, it is easy to organize if you think in the next order.

  1. Ensuring Living Defense Funds
  2. Check your company type DC
  3. Check whether matching or iDeCo is available
  4. Turn only the money that is not used until 60 years old
  5. NA also considers money that can be used on the way

If you think only with tax benefits, you will want to prioritize the final contribution.

However,歳s that cannot be withdrawn until the age of 60 are quite strong. When you can't afford a household account, you can see only tax savings and increase your 。.

Strong system. Therefore, it is necessary to judge that it is not too much.
