My gran passed away and left me her house, which is now worth about £450k. I'm trying to figure out how much inheritance tax I'll actually have to pay. Does the RNRB (residence nil-rate band) apply if I plan to sell it soon, or do I have to live in it for a certain amount of time?
Quick Answer
The Residence Nil-Rate Band (RNRB) of £175,000 applies if your grandmother's main residence is passed to direct descendants, even if you intend to sell it. The criteria focuses on the property's status at death and the beneficiary's relationship, not your future occupancy.
## Understanding Inheritance Tax and the Residence Nil-Rate Band (RNRB)
Inheritance Tax (IHT) is levied on the value of a person's estate upon their death, exceeding certain thresholds. For the 2026/27 tax year, the standard nil-rate band (NRB) is £325,000 per individual. In addition to this, the Residence Nil-Rate Band (RNRB) allows for an extra tax-free allowance when a main residence is passed to direct descendants. The RNRB is currently £175,000 per person. This means an individual could potentially pass on an estate worth up to £500,000 (£325,000 NRB + £175,000 RNRB) free of IHT, and a married couple or civil partners can effectively combine their allowances, potentially passing on up to £1 million tax-free.
The key condition for the RNRB is that the deceased must have owned a home, or a share in one, and their direct descendants (children, grandchildren, step-children, adopted children, and their lineal descendants) inherit it. The property must have been the deceased's main residence at some point, though not necessarily at the time of death if they downsized or sold it to move into care. The RNRB can also be claimed if the property was sold before death, provided a qualifying property was owned. The value of the RNRB is capped at the value of the property or £175,000, whichever is lower.
### Does the RNRB apply if I plan to sell the property soon?
Yes, the Residence Nil-Rate Band (RNRB) can still apply even if you plan to sell the inherited property soon after receiving it. The primary criteria for the RNRB are that the property was the deceased's main residence and is inherited by direct descendants. Your intention to sell the property, or your subsequent occupancy of it, does not typically affect its eligibility for the RNRB. The RNRB is claimed by the deceased's estate, not by the beneficiary, and it is assessed at the point of death.
For example, if your grandmother's estate is valued at £600,000, including the £450,000 house, and she passes her full RNRB of £175,000 and standard NRB of £325,000 to you, the first £500,000 of the estate would be IHT-free. The remaining £100,000 would typically be subject to IHT at 40%, amounting to £40,000. Your decision to sell the house afterwards would not retrospectively invalidate the RNRB claim. The mechanism is designed to support the passing of family homes down generations, irrespective of the beneficiary's immediate plans for the asset.
### What are the main conditions for the RNRB to apply?
For the RNRB to apply, several conditions must be met. First, the deceased must have owned a residential property that was their main residence at some point. Second, the property, or a 'closely inherited' asset (like an interest in a property), must be passed to direct descendants. Direct descendants include children, grandchildren, step-children, adopted children, and their spouses or civil partners. There is also a 'downsizing addition' if the deceased sold their main residence before death and replaced it with a less valuable one, or did not replace it at all, provided their estate meets other criteria.
It is important to note that the RNRB is tapered for estates valued over £2 million. For every £2 that the net value of the estate exceeds £2 million, the RNRB is reduced by £1. This means for estates over £2.35 million, the RNRB is entirely lost. Also, if the property is passed into a discretionary trust, it will not qualify for the RNRB, as discretionary trusts are not considered direct descendants. However, certain types of trusts, like bare trusts or immediate post-death interest trusts, may still qualify. Always seek professional advice for complex trust structures.
### How does this affect Capital Gains Tax (CGT) if I sell the house?
When you inherit a property, its value for Capital Gains Tax (CGT) purposes is typically re-set to its market value on the date of death. This is known as the 'probate value'. If you sell the property shortly after inheriting it, and the sale price is very close to this probate value, there will likely be little or no capital gain, and therefore little or no CGT to pay. For example, if the property was valued at £450,000 on the date of death and you sell it for £455,000, your gain would be £5,000. After deducting your annual exempt amount of £3,000 (for 2026/27), you would have a taxable gain of £2,000.
For higher/additional rate taxpayers, this £2,000 gain would be taxed at 24%, resulting in a CGT liability of £480. If you are a basic rate taxpayer, it would be taxed at 18%, costing £360. However, if the property's value significantly increases between the date of death and the sale, you could face a higher CGT bill. Your annual exempt amount for CGT is £3,000. Residential property gains are taxed at 18% for basic rate taxpayers and 24% for higher/additional rate taxpayers. You also need to report and pay any CGT on residential property within 60 days of completion of the sale.
## Potential IHT Reliefs for Property Investors
* **Transferable Nil-Rate Band:** Spouses or civil partners can transfer any unused standard nil-rate band (NRB) to their surviving partner. This can effectively double the NRB to £650,000 for a surviving partner's estate. The same applies to the RNRB; an unused RNRB can also be transferred, potentially giving a couple up to £1 million in tax-free allowances.
* **Business Property Relief (BPR):** Certain businesses or shares in businesses can qualify for 50% or 100% relief from IHT. This primarily applies to trading businesses, not typically to properties held for investment purposes unless they are part of a qualifying trading business (e.g., a furnished holiday let that provides significant services).
* **Agricultural Property Relief (APR):** Agricultural land, woodlands, or buildings can qualify for 50% or 100% relief from IHT, provided certain conditions regarding ownership and use are met. This is highly specific to agricultural assets and not general investment properties.
## Common Pitfalls to Avoid
* **Assuming full RNRB:** The RNRB is tapered for estates above £2 million. Many investors assume the full £175,000 applies, but if the estate's value exceeds this threshold, the relief is reduced or removed entirely. For example, an estate worth £2.1 million would see the RNRB reduced by £50,000, leaving only £125,000 available.
* **Discretionary Trusts:** Placing a property into a discretionary trust can prevent the RNRB from being claimed, as such trusts are not considered direct lineal descendants. This is a common planning error that can result in higher IHT liabilities. For example, passing a £400,000 house into a discretionary trust would mean that the £175,000 RNRB cannot be used against its value.
* **Missed Transferable Allowance:** Failing to claim the transferable nil-rate bands (both NRB and RNRB) from a deceased spouse or civil partner can lead to significantly higher IHT payments. Many estates overlook this, potentially paying 40% tax on an additional £500,000 that could have been exempt.
* **Ignoring 60-Day CGT Reporting:** If you sell the inherited property and realise a capital gain, you must report this to HMRC and pay the CGT within 60 days of completion. Missing this deadline can result in penalties and interest charges. For example, selling a property with a £20,000 gain will incur a penalty if not reported promptly.
## Steve's Rule of Thumb
When inheriting property, always establish the exact market value at the date of death for both IHT and future CGT calculations; this probate value forms your new cost base for the asset.

Steven's Take
Inheriting a property, especially from a grandparent, can feel like a windfall, but it's often accompanied by complex tax questions. What I've seen repeatedly is that while the RNRB is generous, many people overlook its specific conditions or the transferable allowances. It's not just about the value of the house, but the overall estate and how previous allowances were used. Importantly, the RNRB is about the deceased's main residence passing to a direct descendant; your plans for the property post-inheritance don't impact its eligibility. However, your plans absolutely dictate your own Capital Gains Tax liability. Get the probate value locked down for your cost basis.
What You Can Do Next
Obtain a professional valuation of the inherited property as of the date of your grandmother's death to establish the 'probate value'. This is critical for both Inheritance Tax calculations and for your future Capital Gains Tax basis. You can contact an RICS-accredited surveyor for this.
Review your grandmother's will and any estate planning documents to confirm how the property is bequeathed and to whom, and to ascertain the total value of her estate. This will determine the applicability of the RNRB and any transferable allowances.
Consult with a specialist probate solicitor or an Inheritance Tax accountant to accurately calculate any IHT liability on your grandmother's estate, ensuring all available allowances (NRB, RNRB, and any transferable elements) are correctly applied. Search 'probate solicitor' on The Law Society's website or 'IHT accountant' on ICAEW.com.
If you decide to sell the property, keep meticulous records of all acquisition costs (e.g., solicitor's fees, estate agent's fees) and any enhancement works you undertake before the sale, as these can be deducted from the sale price to reduce your Capital Gains Tax liability. Also remember the 60-day reporting window for residential property CGT.
Consider the wider implications of inheritance on your own financial planning, particularly if the inheritance significantly increases your net worth or income. Speak to a qualified financial adviser (search 'financial adviser' on Unbiased.co.uk) to review your personal tax position and investment strategy.
