If you receive Personal Independence Payment PIP and rely on your vehicle because of mobility needs, a car tax reduction can significantly reduce your annual costs.
At Purpl, we regularly hear from disabled people who did not realise they qualified for 50% off car tax or even full exemption. Some only discover it months after receiving their award decision.
Vehicle tax is not a small expense. Depending on your car, the saving can be hundreds of pounds each year.
This guide explains:
- Who qualifies
- The difference between 50% reduction and full exemption
- How to apply correctly the first time
- What happens if your award changes
If you receive the standard rate mobility component of Personal Independence Payment, you qualify for a 50% car tax reduction. If you receive the enhanced rate mobility component, you qualify for free vehicle tax. You must apply through a Post Office the first time and provide your award letter as proof.

What is a car tax reduction?
Vehicle Excise Duty VED, often called car tax or road tax, is a legal requirement for most vehicles kept or driven on UK roads.
A car tax reduction means you either:
- Pay 50% of the usual rate
- Or pay nothing if you qualify for exemption
Rates vary depending on emissions, fuel type and registration date.
Because many disabled people rely on a car for essential travel rather than convenience, the government provides this relief through the mobility component of certain benefits.
Official GOV.UK guidance:
https://www.gov.uk/vehicle-tax
Purpl tip: Before applying, check your vehicle’s current tax band on GOV.UK so you understand exactly how much 50% would save you.
Who qualifies for a car tax reduction or free car tax?
Eligibility is based strictly on the mobility component of specific benefits.
You qualify for full exemption if you receive:
- Enhanced rate mobility component of PIP
- Higher rate mobility component of Disability Living Allowance
- Armed Forces Independence Payment
- War Pensioners Mobility Supplement
You qualify for a 50% car tax reduction if you receive:
- PIP standard rate mobility component
- ADP standard rate mobility component
If you receive only daily living PIP, you do not qualify.
You cannot get a reduction for getting the DLA lower rate mobility component.
Many people assume a Blue Badge automatically entitles them to free car tax. It does not.

Purpl tip: Always check your most recent award letter. The exact wording of your mobility rate determines whether you receive 50% reduction or full exemption.
50% tax reduction for PIP explained
If you receive the standard rate mobility component of PIP, you are legally entitled to pay half the normal rate of Vehicle Excise Duty.
DVLA confirms this here:
https://www.gov.uk/vehicle-exempt-from-vehicle-tax
Key rules:
- The reduction applies to one vehicle only
- You must register the vehicle in the disabled person’s name.
- You must still renew the tax annually
We regularly see confusion around this point. A reduction does not mean automatic exemption. You must apply.
Official Government source:

Purpl tip: If your award increases to enhanced mobility after a review, inform DVLA immediately so you can move from 50% reduction to full exemption.
Full car tax exemption for enhanced mobility PIP
If you receive the enhanced rate mobility component of PIP, you qualify for free vehicle tax.
You still need to go through the vehicle taxing process. The amount payable will be zero.
The vehicle must:
- Be used for the disabled person’s needs
- Be registered correctly
- Not be used mainly for unrelated purposes
Motability vehicles are taxed automatically within the scheme:
https://www.motability.co.uk
Purpl tip: The exemption can only be applied to one vehicle at a time. Choose the vehicle that supports your essential independence.
Which vehicles qualify?
To qualify for a disabled car tax reduction:
- The vehicle must be registered correctly with DVLA
- It must meet MOT and insurance requirements
- It must be used for the disabled person’s benefit
You cannot apply the relief to multiple vehicles simultaneously.
This is an area where mistakes can lead to penalties if the vehicle is misused.
Purpl tip: If you are buying a new vehicle, inform the dealership before registration so the correct tax class is applied from the start.
How to apply for a disabled car tax reduction
You must complete your first application at a Post Office that handles vehicle tax.
You must apply at a Post Office branch that handles vehicle tax.
What you will need:
- Your benefit award letter
- Your V5C logbook
- A completed V10 form
- Valid MOT certificate if required
- Payment method if applying for 50% reduction
After the first successful application, renewal can usually be completed online or by phone.
Official application guidance:

https://www.gov.uk/government/publications/ins216-how-to-apply-for-free-disabled-tax
Purpl tip: Not all Post Offices process vehicle tax. Check the branch finder tool before travelling to avoid unnecessary journeys.
Refunds and backdating explained
Many people ask whether they can backdate a car tax reduction.
If you become eligible during a tax period, DVLA may refund any full remaining months after it changes your vehicle’s tax class.
However, DVLA does not automatically backdate refunds to the start date of your PIP award.
Therefore, you should apply as soon as you receive your award letter to avoid losing refundable months.
Official refund guidance:
https://www.gov.uk/vehicle-tax-refund
Purpl tip: Apply as soon as your award letter arrives. Waiting can reduce the amount you are refunded.
Common mistakes people make
From conversations within the disabled community, several common mistakes appear repeatedly.
These include:
- Assuming a Blue Badge gives automatic exemption
- Forgetting to update DVLA after a PIP review
- Not realising first applications must be done at a Post Office
- Believing refunds are fully backdated
Understanding these rules reduces the risk of penalties or missed savings.
Purpl tip: Keep digital and paper copies of your award letter so you can respond quickly if DVLA requests evidence.
Frequently asked questions (faqs) about car tax exemptions
Do I still need to tax my vehicle if I qualify for free car tax
Yes. You must still complete the vehicle taxing process even if the cost is zero.
Can someone else drive the car
Yes, as long as the vehicle is used for the disabled person’s benefit.
Can I apply online the first time
No. First applications must be completed at a Post Office that handles vehicle tax.
Does daily living PIP qualify
No. Only the mobility component qualifies.
Is car tax reduction automatically applied
No. You must apply and provide evidence.
In summary
A car tax reduction can reduce your Vehicle Excise Duty by 50 or remove it entirely if you receive the enhanced rate mobility component.
Eligibility depends strictly on the mobility component of qualifying benefits.
For many disabled people and those with long term health conditions, this support helps offset the unavoidable costs of essential travel.
