Extension of time for acquiring a replacement asset starts from receipt of compensation, enabling deposit under CGAS. Where an asset is compulsorily acquired, time limits for acquiring a new asset or depositing capital gains are reckoned from the date compensation is received, not the date of transfer. Deposits into the Capital Gains Accounts Scheme can be made in the previous year compensation is received or by the due date of filing that year's return; proof must accompany the return. Amounts applied plus deposits are deemed cost of the new asset subject to statutory ceilings and scheme withdrawal rules.
