Do I need to enter an acquisition date for my Capital Gains?

When adding Capital Gains you do need to enter an acquisition date for an SA900 but not for an SA100.

SA900

If you don't enter a date of acquisition on an SA900, online submission will fail.

You can enter either the actual or approximate date, as the date is no longer relevant to the calculation of chargeable gains.

NOTE: If the date of acquisition is before 31 March 1982, you'll need to revalue the asset as of that date.

SA100

On an SA100 the box for the acquisition date is for your own use. You can either leave it blank or use it for your own records.

Since the removal of taper relief and indexation allowances for 2008–09, HMRC no longer requires a date of acquisition on an SA100.
