The document summarizes new rules for corporate loss relief in the UK, comparing old and new rules. Under the new rules, there is increased flexibility to use losses but also more restrictions. Losses can now be offset against total profits up to £5 million and 50% of remaining profits, rather than just same trade/type profits as before. Group relief rules were also relaxed to allow surrender of carried-forward losses, not just in-year losses. However, more anti-avoidance rules were introduced to restrict loss utilization in certain sectors and circumstances.
