Legal analysis: At present, the limited liability company adopts the subscribed capital system. The amount and time of capital contribution subscribed by shareholders shall be completely agreed by shareholders themselves and specified in the articles of association. Shareholders can complete their capital contribution in full at the agreed time. When the agreed investment time expires, but shareholders think it is necessary to postpone it, they can adjust the investment time by amending the articles of association. Therefore, the payment time of capital increase should also be agreed by shareholders and stated in the articles of association, and the full payment of capital increase should be completed within the agreed time.
Legal basis: Article 178 of the Company Law of People's Republic of China (PRC). When a limited liability company increases its registered capital, the contribution of the newly-increased capital subscribed by shareholders shall be implemented in accordance with the relevant provisions of this Law on the establishment of a limited liability company. When a joint stock limited company issues new shares to increase its registered capital, shareholders shall subscribe for new shares in accordance with the relevant provisions of this Law on the establishment of a joint stock limited company and the payment of shares.
