Key highlights

  • Initial steps to take after a loss: understanding the practical steps you’ll need to consider such as registering the death, finding the will, and valuing the estate.
  • Tax allowances and reliefs: careful planning could allow for the transfer of unused allowances.
  • Maximising your tax allowances: claiming available allowances, such as the nil-rate band and residence nil-rate band, can help you manage your inheritance tax (IHT).

The upset of losing a second parent is an emotionally difficult time, and understanding the potential implications of estate planning and IHT can also feel extremely daunting.

Here are some of the main considerations to help you through this time.

Working out the initial steps you should take after your loss

At such an emotional time, it’s difficult to turn your mind to the practical steps you need to take after losing a loved one. Here are the key steps you could start with:

  • Register your parent’s death: the first step is to register the death and obtain a death certificate.
  • Check to see if they had a will: you should locate the will, if there is one, if not, the rules of intestacy will apply.
  • Ensure the estate is professionally valued: you’ll need to get a professional valuation of all assets, for example savings and investments, property, art etc.
  • Apply for probate (if needed): this is the legal process of managing your parent’s estate.

Understanding IHT and why it matters

IHT is a tax on the transfer of wealth. In the UK, most people benefit from a nil-rate band (currently £325,000) and residence nil-rate band (currently up to £175,000) – meaning you typically don’t pay IHT on estates up to this value (currently £500,000).

It’s important to note that each estate is assessed independently, following each passing. This is where a key difference arises compared to the first loss in a couple. While the first passing triggers the possibility of using the nil-rate band and residence nil-rate band, with the second loss, any unused portion from the first parent’s estate can be transferred, potentially doubling the tax-free amount available. This means that a couple could potentially pass on up to £1m before IHT becomes due.

Making the most of tax allowances and reliefs

Several allowances and reliefs can help you manage your IHT liability, these include:

  • A deed of variation: this allows you to make changes to a will after your parent has passed away. This could help you manage your IHT.
  • Unused nil-rate band allowances: you can claim unused nil-rate band allowances from the first parent’s estate.
  • The residence nil-rate band: this applies when a property is passed to direct descendants (children or grandchildren). Certain conditions apply.
  • Donating to a charity: leaving a portion of the estate to charity can reduce IHT.

Some common challenges you may face

You may have to deal with an estate with numerous assets or international holdings, which often require specialist advice. There may be family or beneficiary disputes which may need open communication and mediation. There’ll also be deadlines to meet, such as IHT payment deadlines – making sure your make payments within six months will prevent interest charges.
