Timing and Possible Delays
Set by the transaction and filing period
The work is planned around the asset, acquisition history, disposal documents, residence facts, reinvestment evidence and relevant tax period.
What delays it
The work takes longer when ownership records, acquisition costs, improvement invoices, disposal statements, residence dates or foreign tax documents are incomplete.
What to prepare now
You gather your asset, acquisition, improvement, disposal, residence, reinvestment and prior-filing records before the work begins.
Acquisition Evidence, Residence and Reinvestment Records
Acquisition and improvement evidence
You record when each cost was incurred and which asset or improvement it concerns. You attach each improvement invoice to its contract, proof of payment and description so a certified accountant can test the cost against the relevant transaction.
Residence evidence at the disposal date
You separate the evidence for each residence period and mark travel dates that overlap the acquisition, disposal or reinvestment events. A certified accountant uses that file to test the Article 16 position against each residence period.
Reinvestment record sequence
You record the disposal proceeds, each later payment and the legal document for the asset or purpose connected with the claimed reinvestment. A certified accountant compares that sequence with the relevant statutory conditions before the agreed filing is prepared.
Set out your capital gains position
State what you acquired and disposed of, where you lived, which costs you can document and how you used the proceeds.
