About tax planning
Information for Cardiff and South Wales households.
Most UK households leave money on the table each tax year by not using simple allowances. The point of tax planning is not aggressive avoidance schemes (which usually do not work); it is the routine use of the personal allowance, the ISA allowance, the pension annual allowance, the capital gains tax annual exempt amount, and the dividend allowance through the tax year. We set out the 2026/27 numbers and the timing decisions that move them. Where the tax planning crosses into ongoing accountancy work or regulated advice on pension contributions, we refer households to the right specialist.

FAQs
Frequently asked questions on tax planning
What is the most common tax planning mistake UK households make?
+
Not using the ISA allowance. The £20,000 per adult per year ISA allowance is use-it-or-lose-it; you cannot carry it forward. A couple with two adult ISAs leaves £40,000 of tax-free wrapper space on the table for every year they do not contribute, with knock-on effects on capital gains tax and dividend tax on assets held outside ISAs instead. The second most common mistake is leaving employer pension match on the table by not contributing enough to capture the full employer contribution.
How do I crystallise capital gains efficiently?
+
Use the £3,000 annual exempt amount each tax year. Where holdings sit in a general investment account, you can sell up to £3,000 of gains per individual without paying CGT, then buy back the same exposure inside an ISA (bed-and-ISA) or your spouse can buy it back outside the 30-day matching rules (bed-and-spouse). Over a 5-year horizon, a couple can crystallise £30,000 of embedded gains tax-free using these allowances. Above the £3,000, CGT rates are 10% for basic-rate taxpayers and 20% for higher-rate taxpayers on most assets, with 18% and 24% on residential property.
Is salary sacrifice still worth doing for pension contributions?
+
Yes, in most cases, particularly for higher-rate taxpayers. Salary sacrifice converts gross salary into employer pension contributions, saving both income tax and National Insurance on the sacrificed amount. For a higher-rate taxpayer that is roughly a 42% saving on contributions, versus 40% relief on personal contributions made from net pay. Many employers also pass on some of their employer NI saving as an additional pension contribution. The mechanics depend on the employer's scheme rules; check the disclosure pack from your scheme provider before electing.
