Don't forget you can give away up to £3,000 a year, thereby reducing the value of your estate for inheritance tax purposes

But if you do forget you can carry the £3000- gift exemption forward to next year (but for 1 year only)
Also, if you made no gifts last year (6 April 2020 - 5 April 2021) you can carry that year's exemption forward and gift £6,000- this tax year without affecting inheritance tax.
