Hi Frankie22,
Please have a look at the guidance on gifts and examples at
How Inheritance Tax works: thresholds, rules and allowances.
£3000 can be gifted to one person or it can be divided between several people in a tax year.
Birthday or Christmas gifts you give from your regular income are exempt from Inheritance Tax.
You can carry any unused annual exemption forward to the next tax year - but only for one tax year.
Thank you.
