Autumn Budget Sheds Light on CGT Surge – Why ISAs Stay Protected

Autumn Budget Sheds Light on CGT Surge – Why ISAs Stay Protected

Tax Surge in the UK Budget: A Mixed Bag of Numbers

After months of guessing games, Rachel Reeve’s Budget announced a whopping £40 billion increase in taxes, a splash higher than most thought.

Who’s Paying and How Much?

The most wild part of the new plan is the steep rise in employers’ National Insurance:

  • The earnings threshold for the tax moves from £9,100 down to £5,000 starting April 2025.
  • The rate jumps to 15 %, hitting businesses hard.

Other hikes include:

  • DC pension assets will count as part of estates for Inheritance Tax (IHT) from April 2027.
  • A tighter Business Relief and Agricultural Relief for alleviating IHT.

A Glimmer of Relief

Despite the blow, a few bright spots emerge:

  • There’s no cut or new lifetime cap on ISAs— a sigh of relief for savers.
  • The tax‑free cash withdrawable from pensions remains unchanged, keeping many mornings less stressful.
  • Those who pulled out their pension cash recently might revisit their decisions, depending on their providers’ 30‑day cooling‑off periods.

Capital Gains Tax (CGT) Takes a Step Up

Commissioners had already hinted at a CGT hike, so rumours weren’t a surprise—but:

  • Higher‑rate and additional‑rate taxpayers will see a jump from 20 % to 24 %.
  • Basic‑rate taxpayers face a rise from 10 % to 18 %.

The twist? Today’s rates start right now. A mid‑year rise is rare; the previous Gordon Brown era took a similar step but from midnight. That means anyone selling shares this morning might have to pay the higher rate.

A Silver Lining?

Even though the jump is closer to the high end, it doesn’t match the full alignment with Income Tax that some had wanted. The government still keeps a pro‑investment stance.

In practice, though, the higher CGT and trimmed annual exemptions make the tax landscape a bit less friendly for investors. Your ISAs and pensions are now more valuable, as they shield gains and dividends from tax. If you’re married or in a civil partnership, make sure to use both allowances and consider transferring savings between partners to avoid extra taxes.
