What Is the Current Inheritance Tax Threshold?

Many people searching for inheritance tax when second parent dies UK want to know how much of an estate can be passed on before tax becomes payable.

The answer depends on the available inheritance tax allowances.

Nil-Rate Band (NRB)

Every individual has a tax-free allowance called the Nil-Rate Band (NRB).

The current allowance is:

£325,000

This means the first £325,000 of an estate can usually be passed to beneficiaries without inheritance tax.

Residence Nil-Rate Band (RNRB)

An additional allowance may be available where the family home is left to direct descendants, such as:

  • Children
  • Stepchildren
  • Adopted children
  • Foster children
  • Grandchildren

This additional allowance is known as the Residence Nil-Rate Band (RNRB).

The current maximum allowance is:

£175,000

What’s Exempt From Inheritance Tax?

Following are the scenarios where Inheritance Tax is exempted:

Residence Inheritance

If you leave your property or estate to your civil partner or your spouse, no inheritance tax is payable on it.  However, if they pass it on to someone else, tax may be due.

Charity or Funds

Anything you leave for charity, doesn’t apply Inheritance Tax. If you leave either 10% or more of your estate to charity, then the reduced rate of inheritance is from 40% to 36%.

Business Property

Some estates that run a business, or its assets, another relief is applied. This is totally depending on the nature of your business and how long all factors and interest had been held out. This business relief is applied at either 50% or 100%.

Gifts Relief

Gifts of prices up to £3000 in each tax year are exempt from the Inheritance Tax, as they are considered small gifts, like civil partnerships gifts or wedding gifts.

Paying Inheritance Tax When Second Parent Dies

Inheritance Tax is due within 6 months after the second parent’s death. In some scenarios, it can also be paid in installments. If your estate includes property, or any other non-liquid assets like vehicles, equipment or machinery etc, you may be able to delay these payments until they are sold.

If in any case, none of these are available it can also be possible to get an inheritance tax loan from any private finance company. This can help provide some relief during this stressful time.

You must complete an inheritance tax return, which will require details about the deceased’s assets, liabilities and any gifts made seven years prior to their death.

The type of return required depends on the complexity of the estate:

  • IHT205 – A simpler form used for estates below the nil-rate band and without any tax due.
  • IHT400 – A more complex form for estates exceeding the nil-rate band or involving trusts.

You can specify and claim the unused nil-rate band from the first parent against the estate of the second parent on these forms. Once submitted, HMRC will process the return and issue you with a code to use to apply for probate.

Managing Inheritance Tax When a Second Parent Dies

Managing Inheritance Tax when a second parent dies, involves professional skills and steps. They are explained in detail below:

Consulting a Professional

It is advised to consult a professional if you are unaware about the inheritance tax when a second parent dies. Probate solicitors can help you explore all the necessary available allowances, exemptions and ensure the unused nil-rate banks from the first parent are claimed properly.

Gathering Necessary Documentation

Collecting all the necessary documents like the will, property deeds and bank statements. This information is crucial for accurately recording the estate’s value and calculating the owed tax.

Maintaining Accurate Records

Keeping the records of all the financial transactions, valuations of the assets and communications about the estate would be really beneficial. This documentation will be baseless when preparing the inheritance tax return and can easily complete the process when dealing with HMRC.

Future Plans with Estate Planning

When the second parent is alive, discussing the estate planning options with an expert can be beneficial. Planning for the future can help manage the future inheritance tax liabilities when the second parent dies.

How Is Inheritance Tax Calculated When the Second Parent Dies?

Calculating inheritance tax when the second parent dies involves more than simply applying the 40% tax rate. HM Revenue & Customs (HMRC) first determines the total value of the estate before deducting any available allowances, exemptions, and reliefs.

The calculation generally follows these steps:

  1. Calculate the total value of the estate, including property, savings, investments, business assets, and personal belongings.
  2. Deduct outstanding debts, mortgages, funeral expenses, and allowable liabilities.
  3. Apply the available Nil-Rate Band (NRB).
  4. Add any transferable Nil-Rate Band from the first spouse or civil partner.
  5. Apply the Residence Nil-Rate Band (RNRB) if the qualifying home passes to direct descendants.
  6. Deduct any eligible reliefs, such as Business Property Relief or Agricultural Property Relief.
  7. Apply the standard 40% Inheritance Tax rate to the remaining taxable estate.

This process determines how much inheritance tax is payable on second death and whether any tax is due before probate can be granted.

Planning and Mitigation Strategies in this Scenario

Planning is crucial to minimise inheritance tax liability. Start by estimating the value of your estate and considering how you want to distribute your assets.

Make a Will

Having a valid Will is essential to ensure your wishes are carried out. A Will can also help reduce inheritance tax by specifying gifts to charity or setting up trusts.

Use the Nil-Rate Band

Make the most of the tax-free allowance (nil-rate band) by using it wisely. Consider gifting assets or setting up trusts to use up the allowance.

Life Insurance

Consider taking out life insurance to provide a tax-free payout for your beneficiaries. This can help cover inheritance tax liabilities.

Charitable Donations

Leaving a legacy to charity can reduce inheritance tax liability, as charitable donations are exempt from tax.
