Section 115 — SPECIFIED-ACTIVITY LOSS (TONNAGE-TAX-STYLE COMPARTMENT)
Section 115 is the substantive equivalent of 1961 s. 73B / s. 115VC-VR (Tonnage Tax) carry-forward rules. It creates a SEPARATE COMPARTMENT for losses from 'specified activities' — typically tonnage-tax shipping / racehorse owning / etc. — that may be set off ONLY against income from another specified activity. Carry-forward limits as prescribed (typically 4 / 8 years depending on activity-type). Compartmentalisation is a recurring theme in Chapter VII: speculation (s. 113), specified-business (s. 114), specified-activity (s. 115).
PLANNING NOTES
(i) Tonnage-tax shipping companies (s. 116 PGBP-equivalent specified-activity) have isolated loss treatment. (ii) For racehorse-ownership business (1961 s. 74A), loss compartment historical; verify s. 115 inclusion. (iii) For lottery / horse-race / gambling LOSSES — NOT loss-set-off-permitted at all (s. 94 disallowance plus s. 115 isolation).
