Woodlands Relief IHT UK: Timber Deferral, s125 IHTA 1984, How It Works and When to Claim (2026)
Woodlands relief defers — not eliminates — IHT on the value of timber at death. The land is still taxed; the timber charge is postponed until disposal. For commercially managed forestry, 100% Business Property Relief is usually a better outcome.
| Feature | Detail | What is Included | Key Notes |
|---|---|---|---|
| What is deferred | The value of the TIMBER and TREES (underwood) growing on the woodland at the time of death. The timber/trees value is excluded from the IHT calculation on the death — it does not form part of the chargeable transfer at death. | Trees, underwood, standing timber, growing timber. Also any income generated by the woodland between death and disposal (though this is not directly an IHT point — it is subject to income tax in the hands of the personal representatives or beneficiary) | The LAND itself is NOT excluded — the land value IS included in the IHT estate at death and taxed normally. Only the value of the trees/timber growing on the land is deferred. A valuer will need to separate the land value from the standing timber value for the estate accounts. |
| What is NOT deferred — land value | The market value of the bare land (without timber) is included in the deceased's estate and bears IHT at the normal rates at death. If BPR or APR applies to the land, those reliefs reduce the land value for IHT — but woodlands relief itself only applies to the TIMBER, not the underlying land. | The land value is on IHT405 (land and buildings supplement to IHT400). Woodland land may qualify for APR (agricultural property relief — ss115-124 IHTA) if it is part of a farm and managed as part of the agricultural unit — in which case APR applies to the land AND potentially to the trees/underwood (APR and s125 are not mutually exclusive but APR takes precedence where it applies) | For amenity woodland with no agricultural character: the land is valued as bare land (relatively low value) and only the standing timber adds significant value; s125 defers the (often higher) timber value effectively |
| Who makes the election | The personal representatives (PRs/executors) of the deceased's estate, or the person who has taken the woodland under the estate, can elect for woodlands relief within 2 years of the death (s125(1) IHTA 1984). The election is made on IHT400 supplementary page D36. | The 2-year deadline runs from the date of death, not from the grant of probate. Election is irrevocable once made — the PRs or beneficiary cannot change their mind after the election. They must decide within 2yr whether to elect for s125 or pay the IHT on the timber value at death. | Advisability of election: if the timber is likely to fall in value (e.g., market conditions; disease; felling cost increases), paying IHT on the current timber value at death may be better than deferring to a lower future disposal value. If the timber is likely to appreciate, deferral is better — the charge when triggered is at the original death rate, not the future higher rate. |
| When the deferred charge is triggered (s127 IHTA) | The deferred IHT on the timber value becomes chargeable when: (a) the timber or trees are DISPOSED OF — sold, transferred for consideration, or otherwise disposed of (including felled timber sold from the land); (b) the woodland is GIFTED (without consideration) — treated as a disposal for s127 purposes; (c) on the DEATH of the person who inherited the woodland (the charge is triggered on their death — the timber value is assessed again and IHT applied at the original rate) | Disposal of just the TIMBER (felling and selling the logs) triggers the charge. The land itself being sold is NOT a disposal of timber for s127 purposes — only the timber/trees. However, if the land is sold with the timber standing, that includes the timber value in the sale proceeds and triggers s127. | Planning: the family can time the triggering of the deferred charge by timing when timber is felled/sold. In poor markets, delay felling — no disposal = no IHT charge. Sell timber in years when the family's income/estate tax position makes the charge more manageable. |
| Rate of deferred charge (s128 IHTA) | The deferred charge is NOT at the current IHT rate at the time of disposal — it is at the EFFECTIVE RATE applicable at the ORIGINAL DEATH when woodlands relief was first claimed. Effective rate at original death = IHT that WOULD have been payable on the full estate (including timber value) ÷ full estate value (including timber). This gives a percentage rate (e.g., 20%, 15%, etc.). | Example: original death in 2024; full estate including timber = £900k; NRB = £325k; RNRB = £175k; threshold = £500k; IHT at 40% on £400k = £160k. Effective rate = £160k / £900k = 17.8%. Deferred charge rate = 17.8%. When timber later sold for £200k: IHT charge = 17.8% × £200k = £35,600. | The deferred charge rate is usually LOWER than 40% because the effective rate calculation accounts for the NRB/RNRB thresholds. This is often advantageous. If IHT rates increase in the future, the original lower effective rate applies to the deferred charge — a potential benefit of deferral. |
| Interaction with APR (ss115-124 IHTA) | APR takes precedence over woodlands relief (s125) where the woodland qualifies as agricultural property. APR can cover woodland that is 'ancillary to' or 'forming part of' an agricultural holding. If APR applies to the trees (e.g., coppice forming part of a farm), no s125 election is needed. If APR covers only the LAND but not the TIMBER value, s125 can apply to the timber (the land is covered by APR; the timber by woodlands relief). | Agricultural relief rates: 100% for owner-occupied agricultural land (s117(a) IHTA); 50% for tenanted land under AHA 1986 (s116(3) IHTA). Where APR is 100%: the land value is IHT-free; s125 would then be claimed for the separate timber value. Where APR is 50%: the land bears IHT on 50% of its value; s125 defers the timber IHT. | For large farming estates: APR + s125 may be combined; BPR may also be available for the farming business. Get specialist advice on which reliefs apply to which parts of the estate (land, timber, farm business, farmhouse) |
| Interaction with BPR (ss103-114 IHTA) | A commercially managed forestry business (planting, harvesting, selling timber as a trading business) may qualify for 100% Business Property Relief (BPR) under s105(1)(a) IHTA as a 'business or interest in a business'. BPR, if available, is a PERMANENT EXEMPTION — not a deferral. The entire business (land + trees + machinery + other business assets) is exempt from IHT. This is better than s125 woodlands relief (which only defers the timber IHT). | BPR conditions for commercial forestry: (1) it must be a business (trading — not purely investment); (2) the business must have been owned by the deceased for at least 2 years (s106 IHTA); (3) the £1m combined BPR/APR cap (Finance Act 2026) applies from April 2026. Subject to April 2026 cap: first £1m at 100% BPR; above £1m: 50% BPR only. | Amenity woodland (not commercially managed): does NOT qualify for BPR; s125 is the appropriate relief. Commercial forestry: consider BPR first; if BPR is available, it is more beneficial than s125. If BPR is doubtful (borderline trading vs investment): consider claiming both BPR and s125 in the alternative (HMRC will accept one or the other; the PRs can make the election for s125 as a fallback if BPR is challenged) |

Woodlands Relief IHT: Complete Guide
What woodlands relief is and is not — the deferral misconception
Woodlands relief (s125 IHTA 1984) is widely misunderstood. It is NOT a permanent IHT exemption — the timber value is not exempt from IHT forever. It is a DEFERRAL: the IHT charge on the value of trees and timber at the time of the deceased's death is postponed until a later date, specifically until the timber is sold, given away, or until the person who inherited the woodland dies. When the deferred charge is eventually triggered, IHT is paid at the effective rate that applied at the original death — not the current rate. Compare this with Business Property Relief (BPR) or Agricultural Property Relief (APR): these reliefs permanently exempt the qualifying property from IHT. A 100% BPR claim means no IHT ever on that property (subject to the April 2026 £1m cap). Woodlands relief (s125) means: no IHT now on the timber value — but IHT later, when the timber is disposed of. The practical benefit of woodlands relief: it gives the estate time to manage and sell the timber on favourable terms, rather than forcing a timber sale at the date of death (which may be at an unfavourable market price) to fund the IHT bill. The family can manage the woodland for 5, 10, or more years, felling and selling timber gradually and paying the deferred IHT from proceeds at a manageable pace.
The conditions for claiming woodlands relief
Woodlands relief (s125 IHTA 1984) is available where: (1) The land is woodland — trees or underwood growing on land in the United Kingdom. The woodland does not need to be managed as a commercial forestry business; amenity woodland and recreational woodland qualify. (2) The woodland is NOT already covered by APR — if Agricultural Property Relief (ss115-124 IHTA) applies to the trees (because they are part of an agricultural holding), APR takes precedence. APR does not preclude s125, but the two do not overlap on the same asset. (3) The woodland passes on death — s125 only applies on death. There is no equivalent for inter vivos (lifetime) gifts of woodland. Lifetime gifts of woodland are Potentially Exempt Transfers (PETs — s3A IHTA) if to individuals; they escape IHT entirely if the donor survives 7 years. (4) The election is made within 2 years of death — by the personal representatives (PRs) or the person who takes the woodland (if the woodland has been appropriated to that person before the election). The election is on IHT400 supplementary page D36. (5) The election is irrevocable — once made, the PRs cannot change their minds. The deferred charge then hangs over the timber until it is eventually triggered.
Commercial forestry — when BPR is better than woodlands relief
For woodland managed as a commercial forestry business, Business Property Relief (BPR — ss103-114 IHTA) is a far better outcome than s125 woodlands relief. BPR at 100% permanently exempts the qualifying business property from IHT — the timber value is NOT deferred; it is permanently exempt. There is no later deferred charge; no IHT ever on the business value (within the £1m cap from April 2026 under Finance Act 2026). For BPR to apply to a forestry business: the business must be a genuine trading business (not purely an investment), which means active commercial management — planting, managing, harvesting, and selling timber for profit. The business must have been owned by the deceased for at least 2 years immediately before death (s106 IHTA). Professional advice from a rural land agent or timber valuer is essential to determine whether the forestry operation qualifies as a trading business for BPR or is investment-type. HMRC's guidance: HMRC has distinguished between: commercial forestry (BPR potentially available) and investment holding of timber land (BPR not available — the business of holding investments, s105(3) IHTA — excluded from BPR). Where the position is uncertain: PRs may claim BPR AND elect for s125 woodlands relief as an alternative claim — HMRC will accept whichever is available and the PR can rely on s125 if BPR is rejected.
How the deferred charge is calculated — the effective rate explained
When the s127 deferred charge is triggered (on disposal of the timber, on a gift, or on the death of the inheritor), the IHT is calculated using the EFFECTIVE RATE from the original death at which woodlands relief was claimed — not the current IHT rates or the current estate values. The effective rate is calculated as: (IHT that would have been payable on the full estate including the timber value at the original death) ÷ (full estate value including timber value). This gives a percentage. That percentage is then applied to the proceeds or value of the timber at the time of the triggering disposal. Example: original death in 2023; full estate (including timber value of £300k) = £900k; threshold (NRB + RNRB) = £500k; IHT at 40% on £400k = £160k; effective rate = £160k / £900k = 17.78%. Timber later sold in 2030 for £350k (the timber has grown in value): deferred IHT charge = 17.78% × £350k = £62,222. Note: the 17.78% rate is applied to the 2030 DISPOSAL PROCEEDS — not to the original 2023 timber value. If timber prices rise significantly, the deferred charge (expressed as a £ amount) can exceed what the IHT would have been at death (at the lower 2023 value). This is a risk of deferral for appreciating timbers. Conversely, if timber prices fall or the timber is sold for less than the 2023 value, the deferred charge (£ amount) is lower than the 2023 IHT would have been.
Practical planning — when to elect for woodlands relief
The decision to elect for s125 woodlands relief (or not) depends on several factors: (1) Scale of the timber value relative to the estate: if the timber value is large (e.g., £500k timber on a £600k total estate), the immediate IHT on the timber value at death would be significant. Deferral saves cash flow for the estate and allows the woodland to be managed and sold at the right time. (2) Market conditions at death: if timber prices are high at death, deferring the charge means the deferred IHT is calculated on future sale proceeds (which may be lower if prices fall). If timber prices are low at death, paying the IHT now (on the lower value) and getting the timber IHT-free on future sale may be better. (3) Succession planning: if the woodland will pass to the next generation and is expected to be a long-term family asset (not sold for decades), electing for s125 and then eventually the deferred charge being triggered on the next death (at the original effective rate) can work well if the estate is structured correctly. (4) BPR availability: if commercial forestry BPR is available, ALWAYS consider BPR first — it is permanently better. S125 is the fallback for non-commercial woodland. (5) APR availability: if the trees are part of an agricultural holding and APR applies to them, s125 is not needed and the trees are either APR-exempt (100%) or partially exempt. (6) Tax rates: if IHT rates are expected to increase in future years (speculation), deferring at the current lower effective rate locks in a known charge — potentially an advantage. The election must be carefully considered before making — it is irrevocable. Tax advice should be taken before electing.
Frequently Asked Questions
What is woodlands relief for IHT?
Woodlands relief (s125 IHTA 1984) is an inheritance tax deferral for the value of trees and timber growing on woodland that passes on death. It is NOT a permanent exemption. When woodlands relief is claimed: the land value IS included in the IHT estate and taxed normally; the timber/trees value is EXCLUDED from the IHT calculation at death — it is deferred. The deferred charge (under s127 IHTA) arises when the timber is subsequently disposed of (sold or given away) or on the death of the person who inherited the woodland. The rate of the deferred charge (s128 IHTA) is the effective rate applicable at the original death (not the current rate). The election must be made within 2 years of death on IHT400 supplementary page D36, and is irrevocable. Woodlands relief is most useful for amenity woodland where Business Property Relief (BPR) is not available — for commercially managed forestry, 100% BPR (s105(1)(a) IHTA) is a permanent exemption and is a better outcome.
Is woodlands relief better than business property relief for timber?
No — Business Property Relief (BPR) is almost always better if it is available. BPR at 100% (s105(1)(a) IHTA — business or interest in a business) permanently exempts the qualifying property from IHT — there is no deferred charge; no IHT ever on the qualifying value (subject to the April 2026 £1m combined BPR/APR cap under Finance Act 2026). Woodlands relief (s125 IHTA) only defers IHT — the charge is later triggered on timber disposal. BPR applies to commercially managed forestry businesses (planting, harvesting, selling timber for profit); the business must have been owned for at least 2 years (s106 IHTA). Woodlands relief applies to woodland that does NOT qualify for BPR or APR — typically amenity woodland or timber land managed purely as investment. Strategy: claim BPR for commercial forestry; use s125 as a fallback if BPR is challenged or unavailable; consider claiming both in the alternative.
When does woodlands relief apply and when does APR apply?
Agricultural Property Relief (APR — ss115-124 IHTA) takes precedence over woodlands relief (s125 IHTA) where the trees/underwood form part of an agricultural holding. APR may cover: (1) woodland that is ancillary to agricultural land (e.g., coppice on a farm, shelter belts around fields); (2) trees managed as part of the farm husbandry. APR is 100% for owner-occupied agricultural land (s117(a) IHTA — occupied for agricultural purposes by the owner or a company owned/controlled by the owner for at least 2 years before death) or 50% for tenanted AHA 1986 land (s116(3) IHTA). Where APR applies to the trees: woodlands relief is not needed. Where APR applies to the LAND only (not the timber): s125 woodlands relief can be claimed for the timber value separately. For woodland that has no agricultural character (purely amenity or investment woodland not part of a farm): APR does not apply; s125 is the available relief. For commercial forestry (active trading business): BPR (not APR, not s125) is the most beneficial relief.
How is the IHT charge calculated when woodlands relief timber is sold?
The deferred IHT on woodlands relief timber is triggered when the timber is sold (s127 IHTA) and calculated using the EFFECTIVE RATE from the original death (s128 IHTA) — not the current IHT rate. Effective rate calculation: (IHT that would have been payable on the full estate including timber at the original death) ÷ (full estate value including timber). This percentage is then applied to the DISPOSAL PROCEEDS of the timber when sold. Example: original death 2024; full estate including £300k timber = £900k; NRB £325k + RNRB £175k = £500k threshold; IHT at 40% on £400k = £160k; effective rate = 17.78%. Timber sold in 2030 for £400k: deferred charge = 17.78% × £400k = £71,111. If timber falls to £250k by 2030: deferred charge = 17.78% × £250k = £44,444. Note: for partial timber sales (e.g., felling a section of the woodland and selling only some timber), the deferred charge applies proportionally to the sale proceeds from that disposal.
Does woodlands relief apply to a lifetime gift of woodland?
No — woodlands relief (s125 IHTA 1984) is a death-only relief. It applies only when woodland passes on the death of the owner — not on a lifetime gift. A lifetime gift of woodland to an individual is a Potentially Exempt Transfer (PET — s3A IHTA). If the donor survives 7 years from the date of the gift, the transfer falls out of the estate entirely and no IHT applies to the woodland. If the donor dies within 7 years, the PET is drawn back into the estate and IHT is charged (subject to taper relief for years 3-7 — s7(4) IHTA). For lifetime planning: a PET of woodland (with the 7yr survival clock) avoids IHT altogether if the donor survives 7 years — which is better than woodlands relief (which merely defers the charge). However, a lifetime gift of woodland may trigger CGT (gifted at market value — not BPR/holdover exempt unless BPR applies — s165 TCGA holdover applies to gifts of business assets; woodland with BPR may qualify for s165 holdover). Take specialist advice before gifting woodland.
Woodland and Rural Estates Need a Will That Reflects the Assets
A rural estate with woodland, agricultural land, and business interests needs a will that works alongside IHT reliefs — not against them. WillSafe will kits from £39.99.
