A corporate-type DC is a corporate pension plan introduced by a company as a part of its benefit programs while an individual-type DC (iDeCo) is a self-help scheme for building assets for post-work life.
The main differences are as follows.

■ Implementing organization
(1) Corporate-type DC: Company
(2) Individual-type DC (iDeCo): National Pension Fund Association

■ Income deduction for contributions
(1) Corporate-type DC: No income deduction is applied.
In principle, the company makes contributions (plan sponsor contributions), so income deduction is not applied to participants themselves.
＊If you use employee matching contribution (participant contributions) in a corporate-type DC, contributions are deducted from the income of participants.
(2) Individual-type DC (iDeCo): Income deduction is applied.
As participants make contributions, the full amount of contributions is subject to income deduction and income tax and residential tax are reduced.
＊If you use employee matching contribution in a corporate-type DC, you are not allowed to join an individual-type DC (iDeCo).

■ Fees
(1) Corporate-type DC: borne by company (in some cases, may be borne by the individual)
(2) Individual-type DC (iDeCo): borne by the individual
