1. Council tax or business rates: which one applies?

Every residential property in the UK pays either council tax or business rates. Not both. The distinction matters because it can mean the difference between paying thousands per year and paying nothing.

Council tax applies to domestic dwellings by default. If your Airbnb property is your second home or a buy-to-let, it sits on the council tax valuation list.

Business rates (non-domestic rates) apply when the Valuation Office Agency (VOA) classifies your property as a self-catering property and moves it to the rating list. This happens when you meet specific letting thresholds.

The financial incentive to be on business rates is significant. Most small holiday lets qualify for Small Business Rate Relief, which can reduce the bill to zero. Meanwhile, council tax on second homes is getting more expensive every year, with premiums of up to 100% now rolling out across England.

The VOA decides which list your property sits on. You cannot simply choose. You must meet the statutory criteria and provide evidence.

2. The 140/70-day rule (England)

Since 1 April 2023, a property in England qualifies for business rates only if it meets both conditions:

• Available for short-term letting for 140 days or more per year.
• Actually let for 70 days or more in the previous 12 months.

Before April 2023, the old test only required 140 days of availability. There was no actual-letting requirement. The 70-day rule was introduced under the Non-Domestic Rating (Definition of Domestic Property) (England) Order 2023 specifically to stop owners claiming rate relief on properties that were barely used.

2.1 What counts as evidence

The VOA can and does request proof. You should keep:

• Booking confirmations from Airbnb, Booking.com, Vrbo, or other platforms.
• Guest registers with dates and names.
• Bank statements showing rental income.
• Listing URLs and availability calendar screenshots.
• Marketing spend receipts.

The property must be furnished and genuinely available to the public. Letting to friends and family at mates' rates does not count. If you cannot prove 70 days of actual letting, the VOA will move your property back to council tax.

2.2 What happens if you fall below 70 days

The VOA reviews self-catering properties and has been doing so more actively since the 2023 rule change. If your letting activity drops below the threshold, the VOA removes the property from the rating list. You lose Small Business Rate Relief, revert to council tax, and may face the second home premium on top.

3. Small Business Rate Relief

Small Business Rate Relief (SBRR) is the main reason holiday-let owners want to be on business rates. The savings are substantial.

3.1 How it works

Once your property is on the business rates list, the VOA assigns it a rateable value (RV) based on what a competent operator could earn from it. Your relief depends on that value:

• RV £12,000 or below: 100% relief. You pay nothing.
• RV £12,001 to £14,999: Tapered relief, decreasing on a sliding scale.
• RV £15,000 or above: No SBRR.

Most small holiday lets fall under £12,000 rateable value. For context, a typical one or two-bedroom Airbnb in a non-prime area will usually have an RV well under this threshold.

3.2 How to claim

Apply to your local council (the billing authority), not the VOA. The council handles SBRR applications once the VOA has placed your property on the rating list.

3.3 Multiple properties

If you own more than one property, you can only claim SBRR if your additional properties each have an RV below £2,900 and the total RV across all your properties is below £20,000 (£28,000 in London). Hosts with multiple holiday lets are unlikely to qualify for SBRR on all of them.

3.4 The savings

A property with a rateable value of £8,000 would face a business rates bill of roughly £4,000 per year at the current multiplier. With 100% SBRR, that drops to zero. Compare that to council tax (Band D average around £2,100 in 2025-26, plus a potential 100% second home premium) and the case for being on business rates is clear. For a full breakdown of all the costs involved in running a short-term let, see our guide to costs of running a holiday let.

4. The 100% second home premium

Under the Levelling Up and Regeneration Act 2023, local authorities in England can charge a premium of up to 100% on council tax for second homes. That means double council tax.

4.1 Who is affected

The premium applies to properties on the council tax list that are not the owner's sole or main residence. If your Airbnb property is a second home and you have not moved it to business rates (or you tried and failed the 70-day threshold), the premium applies.

4.2 Which councils charge it

Councils must give at least 12 months' notice before implementing the premium. The earliest implementations began in April 2025. Councils that have adopted or announced the 100% premium include Cornwall, North Norfolk, Dorset, Somerset, Bath and North East Somerset, South Hams, North Devon, Westmorland and Furness, Cumberland, East Devon, and Torridge. The list is growing rapidly, particularly in tourist-heavy areas.

Check your local council's website for their current position. If your property is in a popular holiday area, assume the premium is coming if it has not arrived already.

4.3 The compounding effect

If you fail to meet the 70-day actual letting threshold, the VOA moves you back to council tax. You lose SBRR. You gain a second home premium of up to 100%. The financial swing from paying nothing (SBRR) to paying double council tax can be £4,000 or more per year depending on the band and area. This makes the 70-day threshold a critical number to hit.

5. How to switch from council tax to business rates

5.1 The process

1. Confirm you meet the criteria: 140 days available, 70 days actually let (or credible bookings if the property is new).
2. Contact the VOA: Use the online service at GOV.UK or call the VOA directly.
3. Provide evidence: Booking records, listing URLs, income statements, marketing materials.
4. Wait for the VOA decision: There is no guaranteed turnaround. Historically 2 to 6 months, but the VOA has had backlogs since the 2023 rule change.
5. Once listed: Your council issues a business rates bill and removes council tax. Apply for SBRR with the council.

5.2 New properties

If you are setting up a new Airbnb and do not yet have 70 days of letting history, the VOA may accept a business plan and confirmed forward bookings as evidence of intent. However, they will review the property after the first year to confirm actual letting activity.

5.3 Timing

You cannot backdate the switch. The effective date is when the VOA determines the property met the criteria, which is usually the date of your proposal or the date the property became eligible.

6. Wales and Scotland

6.1 Wales

Wales has stricter thresholds than England. Since 1 April 2023, under the Non-Domestic Rating (Definition of Domestic Property) (Wales) Order 2022, a property qualifies for business rates only if:

• Available for letting for 252 days or more per year.
• Actually let for 182 days or more in the previous 12 months.

These thresholds are significantly higher than England's 140/70. Many properties that would qualify in England do not qualify in Wales.

Council tax premiums on second homes in Wales can reach 300%. Gwynedd charges 150%, with several other councils between 50% and 150%. Properties that fail the 252/182 test fall back to council tax and face these premiums.

6.2 Scotland

Scotland requires 210 days available and 70 days actually let per year for business rates. These thresholds were tightened from 1 April 2022.

Council tax premiums on second homes in Scotland can reach 100%. Edinburgh charges the full 100%.

Scotland also has a separate short-term let licensing scheme under the Civic Government (Scotland) Act 1982. All short-term lets require a licence from the local authority, with conditions covering safety standards, insurance, and maximum occupancy. This is an additional requirement on top of the business rates or council tax position. For more on how Scottish rules work, see our guide to avoiding second home council tax.

7. What the FHL abolition changes

The Furnished Holiday Lettings (FHL) tax regime was abolished from 6 April 2025. This was an income tax change, not a council tax or business rates change. The VOA thresholds are unaffected. You can still qualify for business rates and SBRR even though FHL status no longer exists.

However, the indirect impact is significant:

• Weaker financial case: Without FHL benefits (unrestricted mortgage interest deduction, capital allowances, Business Asset Disposal Relief), the overall return from short-term letting is lower for many owners.
• Reduced letting activity: Some owners may scale back, potentially falling below the 70-day actual letting threshold.
• Compounding loss: If you drop below 70 days, you lose SBRR, revert to council tax, and face the second home premium. Combined with the loss of FHL income tax benefits, the financial picture can deteriorate quickly.

The net effect is that hitting and maintaining the 70-day threshold matters more than ever. For a full breakdown of what changed with FHL, see our guide to Airbnb tax in the UK.

8. What to do now: a practical checklist

8.1 If you are already on business rates

• Confirm you are hitting 70 days of actual letting per year. Keep booking records in case the VOA asks.
• Check your rateable value and confirm you are claiming SBRR.
• If you own multiple properties, check whether you still qualify for SBRR across all of them.

8.2 If you are on council tax

• Check whether your property meets the 140/70 threshold (England), 252/182 (Wales), or 210/70 (Scotland).
• If it does, contact the VOA and start the switch process. Gather your booking evidence now.
• If it does not, check whether your council has implemented the second home premium. If so, you may be paying double council tax from April 2025 or 2026.

8.3 If you are not sure

• Run the numbers. Compare the cost of council tax (with potential premium) against business rates (with potential SBRR). The difference can be thousands per year.
• If your property is close to the 70-day threshold, a property manager can help increase occupancy. Management fees are a deductible expense against rental income. For more on what professional management involves, see our guide to property management fees.

8.4 Keep records

Whatever your position, keep detailed records of letting activity, booking dates, income, and availability. The VOA can request evidence at any time. HMRC now receives your platform income data automatically under the Sharing Economy Reporting Regime. Both systems are tightening, and good records protect you from unexpected bills.
