Can I transfer assets to my spouse to reduce our Capital Gains Tax bill?

Yes — transfers of assets between spouses or civil partners who live together are treated as 'no gain, no loss' for Capital Gains Tax, so the transfer itself doesn't trigger a tax bill and the receiving spouse inherits the original acquisition cost. This can be useful for using both spouses' annual exempt amounts, or shifting gains to whichever spouse pays tax at a lower rate, before a subsequent sale to a third party. The transfer needs to be a genuine, unconditional gift of ownership rather than just paperwork, so it's worth having an accountant document it properly.
