3 Expert Tips for GIA Investing in 2026
- The “Income vs. Accumulation” Trap: In a GIA, “Accumulation” funds (where dividends are auto-reinvested) are an accounting nightmare. To make your tax return simpler, always buy “Distribution/Income (Inc)” versions of funds so you can clearly see the dividends received.
- Harvesting the £3,000 Allowance: In 2026, the CGT allowance is £3,000. Each year, you should sell enough of your winners to “realize” this £3,000 gain tax-free, then immediately buy a similar (but not identical) asset. This is known as “Bed and ISA” or “Bed and Breakfasting” (subject to 30-day rules).
- Prioritize the Wrapper: Never invest in a GIA until you have fully utilized your ISA and Pension allowances. A GIA is the “overflow” tank, not the primary engine.
