Furnished vs Unfurnished Rental: Key Tax Differences for Landlords

Whether you are a first-time landlord choosing how to present your property or a seasoned portfolio investor reviewing your tax position, understanding the furnished vs unfurnished rental tax difference matters. The rules affect what you can deduct, whether certain relief schemes apply, and even your Capital Gains Tax position when you eventually sell. This guide walks through every key distinction using verified 2026/27 UK tax figures.

What HMRC Considers Furnished

HMRC does not publish a rigid statutory checklist, but the working principle is straightforward: a property is furnished if a tenant can move in and live there without bringing their own furniture. In practice this means beds, seating, dining furniture, wardrobes, and typically white goods are all present.

A property with only curtains and carpets is generally treated as unfurnished. A property with a few basic items but no beds or seating will usually also be classed as unfurnished. If you are unsure, HMRC guidance suggests asking whether a reasonable tenant would consider themselves able to occupy the property as their home without supplementing the contents — if the answer is no, the property is probably unfurnished for tax purposes.

This distinction matters because several tax reliefs hinge entirely on whether the property meets the furnished threshold.

Replacement of Domestic Items Relief

The single biggest day-to-day tax difference between furnished and unfurnished lets is the Replacement of Domestic Items Relief, which has applied since April 2016.

If you let a furnished property, you can deduct the cost of replacing qualifying domestic items including:

• Furniture (sofas, beds, tables, wardrobes)
• Furnishings (curtains, carpets, floor coverings)
• Household appliances (washing machines, dishwashers, fridge-freezers)
• Kitchenware (crockery, cutlery)

The relief covers the cost of a like-for-like replacement only. If you upgrade — say, replacing a standard washing machine with a premium model — you can only deduct the cost of the equivalent standard item. The excess is a personal expense and not deductible.

Critically, you cannot claim the cost of furnishing the property for the first time. The relief is purely for replacements. So if you are fitting out a new buy-to-let, the initial furniture purchase comes from your own pocket with no tax offset.

Landlords of unfurnished properties cannot claim this relief at all. Even if tenants ask you to provide a washing machine mid-tenancy, and you comply, that cost is not deductible under the replacement relief rules.

Allowable Repairs and Maintenance (Both Let Types)

Regardless of furnishing status, all landlords can deduct genuine repairs and maintenance costs from their rental income. These include:

• Fixing a broken boiler or replacing a like-for-like boiler
• Repainting interior walls
• Repairing roof damage
• Fixing plumbing faults

The key word is repair — restoring something to its original working condition. Improvements are capital expenditure and cannot be deducted against rental income (though they may reduce your CGT bill when you sell). Replacing a single-glazed window with double-glazing is an improvement. Replacing a cracked single-glazed window with a new single-glazed window is a repair.

This rule applies identically to furnished and unfurnished properties.

The Rent-a-Room Scheme: Furnished Only

If you let a room in your own home rather than an investment property, the Rent-a-Room scheme allows you to earn up to £7,500 per year tax-free. If two people share the rental income (for example, a couple who both own the property), each person gets a £3,750 allowance.

This scheme is exclusively available for furnished accommodation in your main residence. If you rent out an unfurnished spare room, you cannot use the Rent-a-Room scheme and must instead declare the rental income through Self Assessment in the normal way.

The £7,500 threshold has not changed for 2026/27. If your gross rents exceed £7,500, you can either:

1. Pay tax on the profit above £7,500 (gross rents minus £7,500), or
2. Opt out and pay tax on actual profit (gross rents minus allowable expenses) — whichever is more beneficial.

Mortgage Interest: No Longer a Direct Deduction

It is worth clarifying a historic misconception still held by some landlords. Prior to April 2017, landlords — both furnished and unfurnished — could deduct mortgage interest directly from rental income. That system was phased out completely by April 2020.

Today, landlords receive a 20% basic-rate tax credit on mortgage interest payments regardless of furnishing status. This means:

• A basic-rate (20%) taxpayer effectively gets full mortgage interest relief, though it now comes as a credit rather than a deduction.
• A higher-rate (40%) taxpayer only gets 20% relief, meaning they pay tax on gross rental income before deducting interest.
• An additional-rate (45%) taxpayer is in the same position — only 20% credit available.

This change hit higher-rate taxpaying landlords hardest and applies equally whether the property is furnished or unfurnished.

Capital Gains Tax When You Sell

When you eventually sell a rental property, CGT applies to the gain — the difference between the sale price and your original purchase cost (plus qualifying improvement expenditure). For 2026/27 the rates are:

• 18% if the gain falls within your basic-rate income tax band
• 24% if you are a higher or additional-rate taxpayer

The Annual Exempt Amount is £3,000 per person for 2026/27.

Furnishing status does not directly affect the CGT rate. However, there is an indirect effect through capital expenditure:

• Permanent fixtures you install (fitted kitchen, built-in wardrobes, bathroom suite) can be added to your cost base, reducing the taxable gain.
• Moveable furniture (sofas, beds, freestanding appliances) does not affect your CGT cost base, even if you leave the items with the property on sale.

So while furnishing a property does not change the CGT rate, investing in fitted improvements rather than freestanding furniture is more tax-efficient from a CGT perspective.

Private Residence Relief (PRR) can reduce CGT if the property was once your main home, and Lettings Relief may apply in limited circumstances. Both reliefs are available regardless of whether the property was furnished or unfurnished during the letting period.

Income Tax on Rental Profits

Rental income from both furnished and unfurnished properties is subject to income tax at exactly the same rates. Your rental profit (income minus allowable deductions) is added to your other income and taxed at:

• 20% (basic rate) on income between £12,571 and £50,270
• 40% (higher rate) on income between £50,271 and £125,140
• 45% (additional rate) on income above £125,140

The Personal Allowance of £12,570 tapers for those earning above £100,000 and disappears entirely at £125,140.

The practical difference is that furnished property landlords can reduce their taxable profit more effectively through the Replacement of Domestic Items Relief, while unfurnished landlords rely solely on repairs, management fees, insurance, and other property-running costs to reduce their bill.

If your rental income plus other income keeps you in the basic-rate band, you may be able to use the £1,000 Property Income Allowance instead of deducting actual expenses — though this is rarely beneficial if you have significant mortgage interest or maintenance costs.

Furnished Holiday Lettings: The Abolished Regime

Before April 2025, short-term holiday lets that met specific criteria (minimum availability and actual letting days) qualified as Furnished Holiday Lettings (FHL). The FHL regime offered generous tax advantages:

• Capital allowances on furniture and equipment (instead of replacement relief)
• Profits counting as earnings for pension contribution purposes
• Access to certain CGT business reliefs

The FHL regime was abolished from 6 April 2025. Holiday lets — whether let on Airbnb, through agents, or directly — are now taxed identically to standard residential lettings. There are no additional allowances for furnishing holiday properties, and the FHL capital allowance pool was closed.

This change removed the most significant tax incentive for furnishing a property to a high standard for short-term letting.

Practical Decision: Furnished or Unfurnished?

From a pure tax perspective, the decision is nuanced:

Furnished makes sense if:

• You are letting to young professionals or students who expect a ready-to-move-in property
• You plan to replace items regularly, generating ongoing Replacement of Domestic Items Relief claims
• You are renting a room in your own home and want Rent-a-Room eligibility

Unfurnished makes sense if:

• Your target tenant is a family or couple who have their own furniture and prefer to personalise their home
• You want to avoid the ongoing management burden of maintaining and replacing furniture
• Void periods are unlikely and tenants tend to stay long-term, so replacement relief opportunities are infrequent anyway

Neither approach is inherently more tax-efficient in isolation. The furnished advantage comes from the regular deductions generated by replacement, not from any structural tax rate difference.

Summary of Key Differences

Both types of landlord must file a Self Assessment return if rental income exceeds £1,000 per year, and both are subject to the same record-keeping requirements. The furnished vs unfurnished rental tax difference boils down to one key relief: the ability to deduct replacement furniture costs — and for room renters, access to the Rent-a-Room scheme.
