Determined contribution is a private system that operates the contribution stake by itself and changes the future payout depending on its operational results.

Typically, it is "business type DC" introduced by the company and "iDeCo" which is subscribed individually.

Both of them are the system of making post-age funds, but who decides whether to withdraw funds, who will pay fees, and who will decide the product lineup.歳 N。, it is also a great feature that can not be pulled up to 60 years old.

Defined contribution is used as a system to compensate for the shortage of re ement and public.

However, there is a 、 in the institution name, but the contents of the operation are investment trusts, period deposits, insurance products, etc. Risk changes depending on how you choose.

Even if you are a company member of the company type DC, you may be able to use iDeCo if you meet the conditions.

However, the contribution limit varies depending on occupation, work place system, or other corporate 。. Since there is an annual system revision, it is better to think about the latest information.

Tax benefits of fixed contribution

Major features of the final contribution are tax benefits.

There are three main stages.

TimingTax Benefits
When withdrawing a stakeIndividual contribution is subject to income deduction
While operatingNon-taxable
When you receiveT payment may be deducted from re ement income and may be subject to public, etc.

In iDeCo, the stake will be covered by a small-scale corporate repayment.

In the case of a matching contribution, the principal's contribution is the subject of income deduction.

Tax benefits are strong. However, it is easy to fail if you decide only tax saving. In principle, it is not a system to put money in the near future because it is not possible to pull up to 60 years old.

Differences between Nと

Both determined contribution s and NAs are compared to the tax system of investment.

However, the usage is quite different.

If you don't use any money until the old age, the final contribution is strong.

NA is more flexible if you have money that is not determined when you use it, money that can be turned into residential funds and educational funds.

It is practical to divide it for the purpose of finance, not inferior to the system.

What to do

Products selected by the final contribution are the original securing type and investment trust when largely divided.

In long-term operation, the lower, distributed and share ratio of trust rewards are effective.

It is easy to avoid the value drop if only the original type is reserved, but it is possible to lose to inflation. On the other hand, if you make 100% of shares, long-term growth is easy to target, while the downward of the middle is large.

I would like to decide my age, period of re ement, and risk tolerance.

How to receive

As a general rule, we receive the final contribution after 60 years old.

However, if you are under 10 years of age, you may be at the beginning of receiving.

There are three ways to receive.

How to receiveTaxes
Paymentmay be subject to re ement income deduction
Tagmay be subject to public, etc. deductions
併用e temporary and

T who have a large amount of re ement may not use re ement income deductions if they receive a temporary fee.

If you receive a public or corporate, you may receive annual income and social insurance premiums.

The way to receive is more likely to be later than in operation, but it is actually quite useful.

Notes when changing jobs

The final contribution may require procedures for changing jobs and re ement.

If you are in a company-type DC, you need to transfer your assets to iDeCo or the following worker system.

If left, it may become automatic transfer. When automatic transfer, assets may not be operated, and only fees may be運用.

If you have a company-type DC guide in your re ement document, it is better not to go back.

Common differences

Make sure to make a final contribution

It is not a system to make money.

If you choose the investment trust, you may crack the original. If you choose a periodic deposit, it is difficult to crack the original book, but it is difficult to understand largely.

It is the person who chooses an operational product even with a company-type DC.

The company prepares a system, but the future receipt depends on the individual’s choice.

Same as iDeCo and NA

Change to Nature

Transfer procedure is required. If left, it may be automatic transfer.
