Offset of Losses

Omer AYDINLI

I am a little bit confused about setting off losses.

Can you offset trading losses against: a) Previous Year, Current Year and Future Year`s trading profit
and b) Current Year`s other incomes such as rental income?

Can you offset property losses against a) Previous, Current and Future Years property incomes and
b) other incomes such as trading incomes.

Can you set off capital losses against a) Previous, Current and Future years capital gains and b) other incomes.

Your helps are really appreciated.
