The £100 Rule Explained

Important tax consideration for parents:

If a parent (or step-parent) gifts money to their child, and that money earns more than £100 in interest per year, ALL the interest is taxed as the parent’s income.

ScenarioTax Treatment
Interest under £100/yearChild’s income (usually tax-free)
Interest £100+/yearParent’s income (uses their PSA)
Money from grandparentsAlways child’s income
Junior ISAAlways tax-free

Example:

  • Parent gifts £5,000 earning 4% = £200 interest
  • This £200 is taxed as parent’s income
  • Solution: Use a Junior ISA instead

Who the £100 rule doesn’t apply to:

  • Grandparents
  • Aunts, uncles, family friends
  • Money the child earned
  • Child Trust Funds and Junior ISAs

Setting Up a Junior ISA

Step by Step

  2. Check child eligibility — UK resident, under 18, no existing JISA/CTF
  3. Apply online — parent/guardian applies as registered contact
  4. Verify identity — child’s birth certificate, parent’s ID
  5. Set contributions — lump sum, regular, or both
  6. Monitor and review — annually check if rate is competitive

Who Can Contribute

Anyone can add money to a Junior ISA:

  • Parents
  • Grandparents
  • Other relatives
  • Friends
  • The child (from pocket money, earnings)

Total across all contributors: Maximum £9,000 per tax year
