Can I transfer shares to my son without tax implications?

Can You Gift Shares to Your Son Without Paying Tax?

Passing on shares to the next generation can be a smart way to help your family while potentially reducing inheritance tax bills — but the timing and rules matter a lot.

If you gift shares to your son, it’s not entirely tax-free from the start. The transfer is considered a "potentially exempt transfer" (PET) for inheritance tax purposes. This means the gift starts out as part of your taxable estate, but if you live for at least seven years after making it, the shares usually fall outside your estate completely. If that happens, no inheritance tax is due when you pass away.

However, there are a few key things to keep in mind. If you don’t survive the full seven years, the tax liability decreases on a sliding scale — known as the "taper relief" — depending on how long you lived after the gift. For example, if you pass away between three and four years later, 20% of the original tax may still apply.

Also, while inheritance tax is the main concern, capital gains tax could come into play if the value of the shares has increased between the time you bought them and when you gift them. You might be hit with a capital gains bill if you’ve used up your annual allowance.

Gifting shares can be a powerful part of long-term financial planning, especially when done well in advance. But because the rules can be tricky, it’s wise to speak with a financial adviser to ensure you’re making the most of tax reliefs and avoiding unintended consequences.

Ultimately, timing and transparency are key — the earlier you act, the greater the potential benefit for your son.
