Council Tax and Business Rates for Landlords UK 2026: Complete Guide

Council tax and business rates are among the most misunderstood costs in UK property investment. Landlords frequently discover, often too late, that they are personally liable for council tax during void periods, that HMO properties carry permanent landlord liability, and that empty commercial property can attract punitive rate premiums of up to 300%. Getting these obligations wrong can cost thousands of pounds per year and create unexpected cashflow problems.

The rules governing who pays council tax and business rates on rental properties are spread across multiple pieces of legislation, modified by local authority discretion, and subject to frequent policy changes. This guide brings together everything UK landlords need to know about their council tax and business rates responsibilities in 2026, covering residential, HMO, commercial, and mixed-use properties.

Whether you own a single buy-to-let flat or a portfolio spanning residential and commercial property, understanding your council tax and business rates exposure is essential for accurate financial planning, proper expense tracking for tax purposes, and avoiding unexpected bills during void periods.

Who Pays Council Tax: Tenant or Landlord?

The general rule for council tax liability is straightforward: the resident pays. When a property is occupied by a tenant under an Assured Shorthold Tenancy (AST) or any other residential tenancy, the tenant is the 'liable person' for council tax purposes. The landlord is not responsible for council tax while the property is occupied by a tenant, regardless of what the tenancy agreement says. Council tax liability is determined by statute (the Local Government Finance Act 1992), not by contract.

However, there are several important exceptions where the landlord becomes the liable person even when the property is occupied.

Council Tax During Void Periods

When a rental property is empty between tenancies, the landlord becomes liable for council tax from the day the tenant vacates. Most local authorities offer a short exemption period for empty properties:

• Class C exemption (empty and unfurnished): Previously offered up to 6 months' exemption. However, most councils have now reduced or eliminated this exemption entirely. Many councils now charge 100% council tax from day one of vacancy.
• Class D exemption (left empty by someone in prison): Exempt while the liable person is detained.
• Uninhabitable property: Some councils offer a reduction (not exemption) of up to 50% for properties that are genuinely uninhabitable due to major structural repairs. This requires council inspection and approval.
• Furnished empty property: Generally no exemption available. Full council tax payable from the first day of vacancy.

Many councils now levy an empty property premium on properties that have been vacant for extended periods. Under the Rating (Property in Common Occupation) and Council Tax (Empty Dwellings) Act 2018, councils can charge the following premiums on top of the standard council tax rate:

HMO Council Tax Rules

Houses in Multiple Occupation (HMOs) represent the most significant council tax risk for landlords. Under the Council Tax (Liability for Owners) Regulations 1992, the owner of an HMO is liable for council tax, not the individual tenants. This applies whether the property is a licensed HMO or not; the definition for council tax purposes is based on occupation, not licensing.

A property is treated as an HMO for council tax purposes if it was originally constructed or subsequently adapted for occupation by persons who do not constitute a single household. The key indicators are: separate letting of individual rooms, shared kitchen or bathroom facilities, and tenants who have individual tenancy agreements rather than a joint tenancy.

Financial Impact

Landlord liability for HMO council tax can have a material impact on investment returns. For example, a 5-bedroom HMO in a Band D property in Manchester would attract annual council tax of approximately £1,800. This cost must be factored into rental yield calculations. The upside is that council tax paid by the landlord on an HMO is an allowable expense that can be deducted from rental income for income tax purposes.

• Verify whether your multi-let property is classified as an HMO for council tax purposes
• Budget for council tax as a landlord expense in your rental yield calculations
• Check if your tenants qualify for council tax discounts (single person, students) that reduce your bill
• Confirm the correct council tax band; HMOs are sometimes incorrectly banded
• Record council tax payments as an allowable expense against rental income
• Consider applying for a council tax reduction if the property is between tenants

Student Property Exemptions

Properties occupied entirely by full-time students are exempt from council tax under Class N of the Council Tax (Exempt Dwellings) Order 1992. This exemption is extremely valuable for landlords operating in university towns and cities. However, the rules are strict: if even one occupant is not a full-time student, the exemption is lost for the entire property.

• Full exemption: All occupants are full-time students enrolled on a course of at least one academic year's duration, with at least 21 hours per week of study.
• Disregard: If a property has a mix of students and non-students, the students are 'disregarded' for council tax purposes. If only one non-student remains after disregarding students, the single person discount of 25% applies.
• Summer vacation: The exemption continues during the summer vacation period, even if students are temporarily absent, provided they remain enrolled.
• International students: International students on student visas who are enrolled on qualifying courses are included in the exemption.

Landlords should collect council tax exemption certificates from their student tenants at the start of each academic year and submit them to the local council. Most universities and colleges issue these certificates automatically. If a student drops out or changes to part-time study during the tenancy, the exemption may be lost, and the landlord (as the HMO liable person) will receive a council tax bill.

Business Rates for Commercial and Mixed-Use Property

Business rates (also known as non-domestic rates) apply to commercial properties and the commercial elements of mixed-use properties. They are calculated based on the rateable value of the property, which is assessed by the Valuation Office Agency (VOA) and updated periodically through revaluations. The most recent revaluation took effect in April 2023.

Small Business Rate Relief

Small Business Rate Relief (SBRR) is a significant benefit for landlords who own and occupy small commercial premises. If your property has a rateable value below £15,000, you may qualify for relief:

Empty Commercial Property Rates

Empty commercial property rates are a major concern for landlords. As discussed in the commercial property management context, the exemption periods are 3 months for office and retail space, and 6 months for industrial property. After the exemption, full business rates are payable. There is no equivalent of the council tax empty property premium for business rates, but the base cost of empty rates can still be substantial.

Council Tax as an Allowable Expense

Council tax paid by the landlord is an allowable expense that can be deducted from rental income for income tax purposes. This applies in two main scenarios:

1. Void periods: Council tax paid while the property is empty between tenancies is a deductible revenue expense. Keep records of all payments and the dates of void periods.
2. HMO liability: Council tax paid by the landlord on an HMO property is fully deductible as a property business expense. This applies for the entire duration of the tenancy, not just void periods.
3. Inclusive rent arrangements: If you include council tax within an all-inclusive rent, the full rent received is taxable income, but the council tax payments you make on behalf of the tenant are a deductible expense. The net effect is tax-neutral.

Business rates on commercial property follow the same principle: rates paid by the landlord during void periods or under terms of the lease are allowable expenses. For landlords with significant void period costs, accurate tracking of council tax and business rates payments is essential for minimising tax liability.

Council Tax Band Appeals and Reductions

Council tax bands were set based on property values as at 1 April 1991 (in England) or 1 April 2003 (in Wales). If you believe your property is in the wrong band, you can challenge it through the VOA. Common grounds for appeal include:

• The property was valued incorrectly relative to comparable properties in the area
• There has been a material reduction in value (e.g., due to changes in the local area such as increased traffic or loss of amenities)
• The property has been physically altered in a way that reduces its value (e.g., conversion from a house to flats)
• A previous challenge on the same property was decided incorrectly

Be aware that an appeal can result in your band increasing as well as decreasing. The VOA will assess the property's value as at 1 April 1991 and may conclude that it was undervalued. Before appealing, research the council tax bands of comparable properties in your street or area using the VOA's online checker. If most comparable properties are in the same band, an appeal is unlikely to succeed.
