Do identical twins need to take immunosuppressants if an organ transplantation happens between them?

If they are genetically identical, does that mean that they can freely donate organs to each other with no negative consequences?

No. In fact, the first transplant was a kidney between identical twins.  The doctor did not consider this the start of anything because he felt that the situation was so rare that it would not be duplicated.

There was a test using a skin graft before they tried the transplant to confirm transplanted material would not be attacked by the immune system.
