The due dates for the payment of your Capital Gains Tax liability arising in the tax year 2015 are as follows:

1. 15^th December 2015 if you made any disposals or transfer of assets in the period 1^st January 2015 to 30th November 2015 inclusive.
2. 31^st January 2016 for all asset disposals and transfers made between 1^st and 31^st December 2015 inclusive.

In Summary

If an asset was disposed of or transferred between 1^st January to 30^th November 2015 giving rise to a chargeable gain then any liability to CGT is due and payable by 15^th December 2015. If, on the other hand, it was disposed of or transferred in the month of December 2015 then any liability arising will be due for payment on or before 31^st January 2016.

Other Points

1. If you have made a disposal under an unconditional contract, the date of disposal is deemed to be the date the contract is signed.
2. If the contract is subject to a condition, then the date of disposal is deemed to be the date the condition is satisfied.

What about CGT Refunds?

Please be aware that there is a 4 year time limit or Statute of Limitations for claiming tax refunds. If, for example, you are entitled to a refund from the tax year 2011, then you must ensure that you complete and send your refund claim to the Revenue Commissioners before 31st December 2015 otherwise you will forfeit this refund.
