Giving wealth away well is harder than it looks. The rules reward those who start early, keep records, and think about the recipient as much as the tax.
Passing wealth on during your lifetime can be one of the most satisfying things you do with it, and one of the most efficient. But it rewards planning, and it punishes the last-minute.
Most larger gifts to individuals are potentially exempt: they fall outside your estate for inheritance tax if you survive seven years. Survive fewer, and a tapered charge can apply. The practical lesson is simple. The clock only helps those who start it, so the value of a gift made at seventy-five and one made at eighty-five can differ a great deal, for no other reason than timing.
Beyond the big gifts, there are annual allowances that quietly do useful work: the yearly exemption, small gifts, and gifts on marriage. Most valuable and most overlooked is the ability to make regular gifts out of surplus income, which can be immediately effective if the pattern and the affordability are documented properly.
Two things separate gifting that works from gifting that causes trouble later. The first is records: dates, amounts, and the income the regular gifts came from. The second is judgement about the person receiving. A gift that lands on someone unready for it is not a kindness. We tend to plan the tax and the readiness together, because the point was never only to save tax.
