Step 1: Usual treatment of goodwill.
When goodwill is brought in cash by a new partner, it is credited to the old partners’ capital accounts in their sacrificing ratio.
Step 2: Case of non-payment.
If the new partner does not bring goodwill in cash, then his capital account is debited (reduced), and the sacrificing partners are compensated by crediting their capital accounts.
Step 3: Conclude.
Hence, when goodwill is not brought in cash, it is debited to the New Partner’s Capital A/c.
Final Answer:
\[
\boxed{\text{New Partner’s Capital A/c}}
\]
