The moment a UK landlord adds any taxable supply to an otherwise exempt residential portfolio, the simple "exempt-no-recovery" position ends. The portfolio becomes partially exempt: input VAT on costs that relate to the new taxable supply is recoverable, input VAT that relates to ongoing exempt residential rents is not, and input VAT on shared overhead (accountancy, software, central administration, professional fees, marketing) must be apportioned between the two. The apportionment rules sit in VAT Regulations 1995 regulations 99 to 110, with practical guidance in HMRC VAT Notice 706.
This page sets out the operational mechanic: direct attribution under reg 101(2)(b) and (c), residual apportionment by the output-values ratio under reg 101(2)(d), the de-minimis safety valve under reg 106, the annual adjustment under reg 107, and the special-method approval route under reg 102 for cases where the standard method gives an unfair result. The mechanic is calculation-heavy but the cash impact on a multi-property landlord can move several thousand pounds of recovery a year; on a developer holding zero-rated stock alongside continuing residential lets, the special-method case can move much more.
When Partial Exemption Arises
Partial exemption is triggered by mixed supplies. Specifically, a VAT-registered business is partially exempt for a period if it has made both taxable supplies (standard-rated, reduced-rated, or zero-rated) AND exempt supplies in the period, AND has input VAT incurred in the period.
For UK landlords the typical trigger is one of:
- A residential AST portfolio plus an opted commercial property.
- A residential portfolio plus a holiday-let business above the £90,000 VAT registration threshold.
- A residential portfolio plus opted parking spaces let separately from any dwelling.
- An ongoing residential rental business plus a commercial development held as zero-rated trading stock on first grant.
- A serviced-accommodation operator (standard-rated) plus continuing ASTs on the long-let element of the portfolio.
Without a taxable supply, partial exemption does not arise: a pure-residential landlord is fully exempt and cannot register for VAT (no taxable supplies to invoice). Without an exempt supply, partial exemption does not arise: a pure-commercial landlord with everything opted is fully taxable. The intermediate ground is the partial-exemption zone.
The Standard Method: Attribution Then Apportionment
Reg 101 sets out the standard method as a two-stage process.
Stage 1: Direct attribution
Each input invoice is categorised:
- Wholly taxable (reg 101(2)(b)): the input relates exclusively to taxable supplies. Input VAT is recovered in full. Examples: roof repair on the opted commercial unit; cleaning of the holiday-let; surveyor's fee for the opted property's refurbishment.
- Wholly exempt (reg 101(2)(c)): the input relates exclusively to exempt supplies. Input VAT is not recovered. Examples: boiler service on a residential AST flat; letting agent's fee on a residential property; communal-area cleaning of a wholly residential block.
- Residual: the input relates to both. Input VAT is partially recoverable per stage 2. Examples: accountancy fees for the whole portfolio; portfolio-management software; the landlord's marketing and website costs.
Direct attribution is the largest line of defence against unnecessary recovery loss. Where an invoice can be clearly tied to one side of the portfolio, the recovery is binary (100% or 0%). Only the genuinely residual lines fall into stage 2.
Stage 2: Residual apportionment
The standard-method formula under reg 101(2)(d):
Recovery percentage = (Value of taxable supplies in the period, VAT-exclusive) ÷ (Value of all supplies in the period, VAT-exclusive) × 100, rounded up to the next whole number.
The percentage is applied to the residual input tax pot to give the recoverable portion. The non-recoverable portion is treated as wholly exempt for that period.
The rounding-up rule (Notice 706 section 4) gives the taxpayer a small additional recovery each period. The rule is overridden where residual input tax exceeds £400,000 monthly average (a large-business threshold rarely hit by single-portfolio landlords); above that threshold, recovery is computed to two decimal places without rounding up.
Worked example: a mixed-portfolio landlord
An anonymised UK landlord operates: a residential AST portfolio generating £200,000 of annual exempt rent, plus a single opted commercial unit generating £100,000 of annual taxable rent (standard-rated). Annual residual input VAT (accountancy, software, central admin) is £8,000.
| Line | Calculation | Amount |
|---|---|---|
| Total taxable supplies (period) | Opted commercial rent | £100,000 |
| Total exempt supplies (period) | Residential AST rent | £200,000 |
| Standard-method recovery % | £100,000 ÷ £300,000 × 100 = 33.33%, rounded up | 34% |
| Residual input VAT | Pot | £8,000 |
| Recoverable residual | £8,000 × 34% | £2,720 |
| Non-recoverable residual | £8,000 × 66% | £5,280 |
On top of the residual recovery, the landlord also recovers in full any wholly-taxable directly-attributed input VAT (the cost of running the opted commercial property in isolation), and does not recover any wholly-exempt directly-attributed input VAT (the cost of the residential side). The residual recovery is the marginal line where attribution effort matters.
The De-Minimis Test
Reg 106 provides a safety valve: a partially-exempt business with a small exempt element is treated as fully taxable and recovers all input VAT, including the exempt-attributable element. Both legs of the test must be met in the period:
- Leg 1 (£625 monthly average): exempt input tax (the input VAT directly attributed to exempt supplies, plus the exempt-attributable portion of residual input VAT) must not exceed an average of £625 per month across the period. For a quarter, this is a £1,875 cap; for an annual longer-period, this is £7,500.
- Leg 2 (50% cap): exempt input tax must not exceed half of total input tax for the period.
If both legs are met, the period is "de-minimis" and recovery is 100% for the period. The exempt input tax is treated as if it were taxable-attributable. The annual adjustment then re-tests the position across the full longer-period.
For most pure-residential-with-one-small-commercial-let landlords, the de-minimis test will fail because the residential side's directly-attributed input VAT alone (boiler services, letting agent commission, repairs and decorations on multiple flats) will breach £625 per month easily. The de-minimis safety valve mainly helps businesses where the exempt element is genuinely incidental.
Worked example: a borderline de-minimis position
An anonymised landlord runs a single opted commercial property generating £180,000 of taxable rent plus three residential flats above it generating £60,000 of exempt rent. Quarterly input VAT analysis:
| Quarter | Wholly taxable VAT | Wholly exempt VAT | Residual VAT | Exempt-attributable total |
|---|---|---|---|---|
| Q1 (commercial routine only) | £1,200 | £400 | £900 | £400 + (£900 × 25% exempt) = £625 |
| Q2 (commercial routine + flat boiler replacement) | £950 | £2,100 | £900 | £2,100 + £225 = £2,325 |
| Q3 (commercial routine + flat redecoration) | £800 | £1,400 | £900 | £1,400 + £225 = £1,625 |
| Q4 (commercial routine only) | £1,100 | £350 | £900 | £350 + £225 = £575 |
Per-quarter de-minimis test (£625 × 3 months = £1,875 quarterly cap):
- Q1: £625 exempt-attributable ≤ £1,875 cap, and £625 ≤ 50% of total input VAT in the quarter. PASS. Full recovery permitted including the exempt-attributable element.
- Q2: £2,325 exempt-attributable > £1,875 cap. FAIL. Standard-method recovery applies.
- Q3: £1,625 ≤ £1,875 cap; second leg also met. PASS.
- Q4: £575 ≤ £1,875 cap; second leg met. PASS.
So in Q1, Q3, and Q4 the landlord recovers all input VAT including the exempt-attributable portion. In Q2 the standard-method recovery applies (around 75% on the residual pot only, and the £2,100 wholly-exempt is unrecoverable). The annual adjustment under reg 107 then re-tests the position across the whole longer-period: £625 + £2,325 + £1,625 + £575 = £5,150 total exempt-attributable for the year, against a £7,500 annual cap (£625 × 12 months). The annual position is PASS and full recovery is reinstated, with the Q2 standard-method outcome refunded in the annual-adjustment return.
The Annual Adjustment
Reg 107 requires a single annual reconciliation at the end of each VAT longer-period (typically 12 months ending 31 March, 30 April, or 31 May, depending on the landlord's VAT quarter structure):
- Add up taxable supplies for the full longer-period (VAT-exclusive).
- Add up all supplies for the full longer-period (VAT-exclusive).
- Compute the annual recovery percentage using the standard-method formula, rounded up.
- Compute the residual input tax for the full longer-period.
- Apply the annual recovery percentage to the annual residual input tax to give the annual recoverable.
- Compare against the sum of quarterly recoverable amounts already claimed.
- Account for the difference (positive or negative) in the next VAT return.
The annual figure is the final position. The quarterly figures are provisional. The annual adjustment also re-tests the de-minimis position across the longer-period: a business that passes de-minimis quarter-by-quarter can fail on the annual aggregate, triggering a partial-exemption adjustment for the year as a whole.
Acceleration is permitted (since April 2009): the annual adjustment can be performed in the final return of the longer-period rather than the first return of the next longer-period. This is the cleaner approach for businesses with predictable quarterly patterns; it requires no HMRC notification.
Worked example: an annual adjustment with a refurbishment year
An anonymised landlord has a typical mixed portfolio: £400,000 of exempt residential rent and £200,000 of opted commercial rent (annual). In a steady year, residual input VAT of £15,000 is apportioned on a 34% recovery percentage (£200,000 ÷ £600,000 rounded up), so £5,100 of residual is recovered.
In a refurbishment year a £300,000 (VAT-exclusive) refurb on the opted commercial unit produces an extra £60,000 of input VAT. That £60,000 is wholly-taxable directly-attributed (the refurb is for the opted property), so it is recovered in full from the relevant quarter. The annual output values are unchanged (the refurb itself does not generate output until the next year's rent). The standard-method recovery percentage is unchanged at 34%. The residual input VAT pot grows modestly with additional accountancy and project-management overhead, perhaps to £18,000. Residual recovery: £18,000 × 34% = £6,120.
Quarter-by-quarter the landlord recovered residual VAT at percentages between 33% and 36% depending on quarterly input VAT and quarterly mix; the annual adjustment recomputes a single 34% on the full-year residual of £18,000, gives £6,120 of total residual recovery, compares against the £5,800 already recovered cumulatively across quarters, and the £320 difference is recovered in the annual-adjustment return.
The same refurb under a special method that uses floor-area allocation (where the commercial element occupies 60% of the building by floor area) would produce a 60% recovery percentage on residual, giving £18,000 × 60% = £10,800 of residual recovery, a £4,680 uplift on the standard method. The special-method modelling case is in the next section.
When the Standard Method Is Unfair: Special Methods
The standard method assumes that residual input tax follows the output-values ratio. In practice that is sometimes a poor proxy. Where the standard-method recovery percentage does not fairly reflect the use of inputs in the business, reg 102 permits an approved special method.
Common landlord triggers for a special method:
- Floor-area methods. A landlord with mixed-use buildings (residential above, commercial below) where the commercial element's input VAT recovery is genuinely tied to its floor-share rather than its rent-share. Output values may underweight the commercial element; floor-area may be a fairer proxy.
- Transaction-count methods. A serviced-accommodation operator with high transaction volume on the standard-rated side and few long-let transactions on the exempt side. Output values may inadequately reflect the operational burden of the taxable side.
- Sectorised methods. A landlord operating multiple distinct business sectors (residential lettings, commercial lettings, holiday-let, development) where a single output-values ratio is too coarse.
- Time-apportioned methods. A property with mixed-use occupancy patterns where the commercial element is in use only during business hours.
The application is on form VAT (PE2) submitted in writing to HMRC, with a declaration that the method is fair from the effective date and for the foreseeable future (Notice 706 section 6). HMRC approval is required before the method takes effect; backdating is not generally available. The method then runs until either party withdraws it (with at least 60 days' notice typically required).
Common Landlord Scenarios
| Scenario | Typical partial-exemption position |
|---|---|
| Pure residential AST portfolio | Fully exempt; partial exemption does not arise; no VAT registration |
| Residential portfolio + single small opted commercial unit | Partial exemption; standard method likely fine; de-minimis usually fails |
| Residential portfolio + holiday-let trade above £90k | Partial exemption; standard method on residential vs holiday-let ratio |
| Residential portfolio + opted parking spaces let separately | Partial exemption; standard method; review for de-minimis quarterly |
| Developer holding zero-rated trading stock + residential AST portfolio | Partial exemption; standard method may underweight zero-rated supplies; consider special-method application |
| Serviced accommodation operator + long-let residential | Partial exemption; output-values method usually adequate; sectorised method considered for portfolios above £2-3m turnover |
| Mixed-use single building (commercial below, residential above) | Partial exemption; consider floor-area special method where output-values does not reflect input use fairly |
Interaction with the Capital Goods Scheme
Partial exemption is the period-by-period recovery framework on input VAT. The Capital Goods Scheme is the 10-year re-test framework on capital expenditure over £250,000 VAT-exclusive (for land and buildings). The two run in parallel: each CGS item's annual interval recovery percentage uses the partial-exemption recovery method (standard or approved special) applied to that year's supplies. Changes in the portfolio's partial-exemption percentage flow through to each CGS item's annual interval adjustment.

OTT Interaction
Opting to tax under VATA 1994 Sch 10 converts an exempt commercial supply into a taxable supply. The immediate consequence in partial-exemption terms: taxable supplies increase, the standard-method recovery percentage rises, and previously residual-attributable input VAT becomes more recoverable. Inputs directly attributable to the newly-opted property move from "wholly exempt" to "wholly taxable" from the effective date of the option.
The depth treatment of the OTT mechanic is in our option-to-tax guide. For partial-exemption purposes the operational point is that the OTT moves the recovery ratio in the period of the election and onwards.
Records and MTD
MTD for VAT (mandatory for every VAT-registered business since 1 April 2022 per VAT Notice 700/22) requires digital records of every input invoice with the attribution decision flagged: wholly taxable, wholly exempt, or residual. Most MTD-compatible software handles this through a per-invoice categorisation field with the standard-method computation built into the period-end function.
Reg 106A and Notice 706 section 8 set the partial-exemption record requirements: enough detail to demonstrate, on inspection, the basis for each attribution decision and the calculation of the recovery percentage. Records must be retained for six years from the end of the period.
Common Partial-Exemption Mistakes
- Assuming exempt rent does not affect overhead recovery once a property has been opted. The exempt residential side still pulls the recovery percentage down on residual input VAT.
- Missing the annual adjustment. The quarterly figures are provisional only; the annual figure is the final position. Failing to compute it at the longer-period end leaves a misstatement that HMRC will pick up on inspection.
- Lazy direct attribution. Treating everything except clearly-taxable invoices as residual maximises the exempt-attributable pot and depresses recovery. Tight invoice-by-invoice attribution materially improves recovery.
- Applying the de-minimis test once a year instead of every period. The test must be applied every VAT return period AND at the annual adjustment. A quarter that passes does not mean the year passes.
- Not modelling a special method for portfolios where the standard method is clearly unfair. The special method requires effort to apply for but can lift recovery materially for developer-and-landlord hybrids or mixed-use single-building portfolios.
- Forgetting the rounding-up rule. The standard-method percentage is rounded up to the next whole number (under £400,000 monthly average residual): a 33.33% calculation becomes 34%, not 33%. The small uplift compounds across a year of residual recovery.
- Treating zero-rated supplies as exempt. Zero-rated is taxable (at 0% VAT) for partial-exemption purposes. A developer making zero-rated first-grant sales is making taxable supplies; the supplies count in the numerator of the standard-method ratio.
