Landlords

1) Reform or replace Stamp Duty Land Tax (SDLT)

Options:

• Restore higher nil-rate thresholds or re-profile bands to reduce upfront buying costs for first-time buyers and mover chains.
• Replace SDLT for owner-occupiers with an annual/property wealth tax or an annual charge payable on sale (proposals reported this autumn would target homes above a threshold such as £500,000)

Likely market effect:

• Cutting SDLT thresholds (or reinstating more generous first-time buyer reliefs) would likely boost transactional activity quickly because SDLT is an upfront, purchase-time wedge block. Buyers would respond to lower up-front costs.
• Replacing SDLT with an annual or “moving” charge spreads the cost over time and can reduce the disincentive to move created by a high one-off tax, but it risks making some homeowners (particularly in high-value areas but with low incomes) worse off, and could depress high-end sales if it’s perceived as a recurring wealth charge. Lower property transactions / house moves would significantly impact tax revenue in the wrong way because of losing the revenue from current stamp duty and vat charges by service providers working in the house market, and of course the loss of vat from the vast amount of services created by a house moves such as new kitchens and bathrooms.

2) Higher or more targeted rates for second homes / buy-to-let investors

Options:

• Increase the surcharge on second homes / additional properties (currently an extra SDLT percentage for additional dwellings), raise it further, or extend similar surcharges to more transactions.
• Introduce a landlord-specific levy or higher effective tax on portfolio owners.

Likely market effect:

• Further targeting landlords would likely accelerate some small-scale exits from the sector (already under pressure), reduce investment demand and could tighten supply in the private rented sector, pushing rents higher in the short term. Without a meaningful social housing level in the UK targeting landlords would not help tenant because rents would increase and supply of housing stock availability would reduce due to landlords exiting the market.

3) Capital Gains Tax (CGT) changes on property

Options:

• Raise CGT rates or reduce the annual exempt amount (AEA) — both would raise the tax burden on gains when properties are sold.
• Tighten or reduce Principal Private Residence (PPR) relief for high-value homes (for example limiting relief above a threshold) — a targeted approach that raises revenue from the most valuable homes without touching ordinary households.

Likely market effect:

• Higher CGT or a reduced AEA would increase the cost of selling investment and second-home property. This could potentially lock in existing owners and reduce transactions.
• Cutting PPR relief for expensive homes would mainly hit the top end — potentially cooling top end market segments and raising effective holding costs for high-value owners. This could impact high-end prices because buyers are sensitive to potential future taxes. Lower property transactions / house moves would result and less tax revenue because of losing the revenue from current stamp duty and vat charges by service providers working in the house market. Result, a less mobile and flexible house market.

4) Measures aimed directly at landlords’ tax treatment and rental incomes

Options:

• Introduce National Insurance on rental profits or allow some form of additional tax on landlord income.
• Rollback of tax breaks — although mortgage interest relief was largely reformed previously, further tweaks could be considered (for example reintroducing some relief, or increasing taxes on rental income).

Likely market effect:

• New employer-style taxes on rental profits or higher effective rates would make more and more small landlords financially unviable, likely reducing rental supply. This would put upward pressure on rents and increase housing insecurity for tenants.

5) Council tax / local property taxation reform

Options:

• Reform or revalue council tax bands, or begin a gradual move toward a more modern local property tax (often mooted as a replacement for council tax).
• Offer reliefs or targeted support for low-income homeowners in high-value areas.

Likely market effect:

• Revaluation or an annual local property tax increases the ongoing cost of homeownership (especially for those currently paying low council tax relative to property value), which can reduce mobility as owners stay put to avoid higher bills, depressing transactions in affected areas.

Likely short-term market responses

• Transaction volumes are likely to fall pre-announcement and remain subdued until the policy details are known — sellers delay listings, buyers wait for clarity. Data show buyers already pulling back ahead of the Budget.
• Upper-end weakness: rumours of wealth-targeting measures have already led to a steeper slowdown at the top of the market. If the Government confirms higher recurring or one-off charges on expensive homes, the prime market could see further correction.
• Rental squeeze: any measures that raise landlords’ costs (higher tax on rental profits, restricted reliefs, or higher transaction taxes on replacement purchases) could reduce supply and raise rents in the short term. Targeting landlords will be detrimental.

Political and administrative constraints

• Revenue vs incentive trade-off. Taxes that raise quick revenue (raising CGT rates, lowering CGT allowances) are administratively straightforward but can chill transactions and lock in property owners. Structural reforms (replacing SDLT with an annual tax) could be fairer economically but are complex to implement and politically sensitive. 
• Distributional optics. Targeting high-value homes is politically popular in some quarters, but any policy that hits “ordinary” homeowners in expensive areas (for example an annual property charge) risks backlash.
