Introduction to Audi Company Car Tax: What You Need to Know
Company car tax (officially known as Benefit-in-Kind or BIK tax) represents one of the most significant financial considerations for both employers and employees when providing or receiving an Audi company car. This tax is calculated based on the car’s P11D value (its list price including VAT and delivery charges), its CO₂ emissions, and the employee’s income tax band.
The UK government uses company car tax as a mechanism to:
- Encourage the adoption of lower-emission vehicles through preferential tax rates
- Generate revenue from what’s considered a taxable benefit
- Reflect the environmental impact of different vehicle choices
For Audi drivers, understanding these calculations becomes particularly important because:
- Audi’s premium positioning means higher P11D values, which directly increase tax liability
- The brand’s diverse powertrain options (from high-performance petrol to fully electric e-tron models) create vastly different tax outcomes
- Many Audi models sit in higher tax bands due to their performance capabilities
This calculator provides precise, HMRC-compliant calculations that account for all these variables. Whether you’re considering an Audi A4 Avant as a practical company workhorse or an e-tron GT as an executive electric vehicle, our tool will show you exactly what your tax liability will be before you commit.
Step-by-Step Guide: How to Use This Audi Company Car Tax Calculator
Our calculator follows the exact methodology used by HMRC to determine company car tax. Here’s how to get accurate results:
-
Select Your Audi Model
Choose from our comprehensive list of current Audi models. The calculator includes both combustion-engine and electric vehicles, as their tax treatments differ significantly.
-
Specify Fuel Type
Select between petrol, diesel, electric, or plug-in hybrid. This is crucial because:
- Electric vehicles currently enjoy a 2% BIK rate (2024/25)
- Plug-in hybrids get preferential rates based on their electric range
- Diesel vehicles incur a 4% supplement unless they meet RDE2 standards
-
Enter CO₂ Emissions
For combustion-engine vehicles, input the official WLTP CO₂ figure in g/km. You can find this in the vehicle’s V5C logbook or on Audi’s official website. For electric vehicles, this will automatically be set to 0g/km.
-
Electric Range (for PHEVs)
If you’ve selected a plug-in hybrid, enter its official electric-only range in miles. The longer the range, the lower the BIK percentage (down to a minimum of 2% for ranges over 130 miles).
-
Input List Price
Enter the car’s full list price including VAT and delivery charges, but before any discounts. This is known as the P11D value. For accurate figures, use Audi’s official price lists or configurator.
-
Select Tax Year
Choose the relevant tax year. BIK rates change annually, with the government typically announcing rates several years in advance to allow for planning.
-
Income Tax Band
Select your income tax band (20%, 40%, or 45%). Your company car tax is calculated as a percentage of the BIK value at your marginal rate.
-
Capital Contribution
If you’re making a personal contribution towards the car (up to £5,000), enter this amount. This reduces the P11D value for tax purposes.
-
Review Results
The calculator will display:
- Your P11D value (after any capital contribution)
- The applicable BIK percentage
- Annual BIK value (P11D × BIK%)
- Monthly and annual tax liability
- Employer’s National Insurance contribution (13.8%)
Understanding the Formula: How Audi Company Car Tax is Calculated
The calculation follows this precise sequence:
1. Determine the P11D Value
The P11D value is the car’s list price including:
- Manufacturer’s recommended retail price
- VAT (currently 20%)
- Delivery charges
- Any optional extras fitted at first registration
Formula: P11D = List Price + VAT + Delivery - Capital Contribution (max £5,000)
2. Calculate the BIK Percentage
The BIK percentage depends on:
| Fuel Type | CO₂ (g/km) | Electric Range (miles) | 2024/25 BIK % |
|---|---|---|---|
| Petrol | 0 | N/A | 2% |
| 1-50 | N/A | 2-14% | |
| 51-100 | N/A | 15-24% | |
| 101+ | N/A | 25-37% | |
| Diesel | 0 | N/A | 2% |
| 1-50 | N/A | 6-18% | |
| 51-100 | N/A | 19-28% | |
| 101+ | N/A | 29-37% | |
| Plug-in Hybrid | 0 | 130+ | 2% |
| 0 | 70-129 | 5% | |
| 0 | 40-69 | 8% | |
| 1-50 | 30-39 | 11% | |
| 1-50 | <30 | 14% | |
| 51+ | Any | 14-37% | |
| Electric | 0 | N/A | 2% |
3. Calculate Annual BIK Value
Annual BIK Value = P11D × (BIK % ÷ 100)
4. Determine Tax Liability
Annual Tax = Annual BIK Value × Income Tax Rate
Monthly Tax = Annual Tax ÷ 12
5. Employer’s National Insurance
Employers must pay 13.8% Class 1A National Insurance on the BIK value:
Employer NI = Annual BIK Value × 0.138
All calculations are verified against official HMRC guidance and updated annually to reflect legislative changes.
Real-World Examples: Audi Company Car Tax Scenarios
Example 1: Audi A4 40 TFSI S line (Petrol)
- Model: A4 Saloon 40 TFSI S line
- List Price: £42,310
- CO₂ Emissions: 148 g/km
- Fuel Type: Petrol
- Tax Year: 2024/25
- Income Tax Band: 40%
- Capital Contribution: £0
Results:
- BIK Percentage: 32%
- Annual BIK Value: £13,539.20
- Annual Tax: £5,415.68
- Monthly Tax: £451.31
- Employer NI: £1,868.31
Analysis: This represents a typical mid-range Audi company car. The 32% BIK rate reflects its petrol engine and 148g/km CO₂ emissions. The 40% tax band significantly increases the liability compared to a basic-rate taxpayer.
Example 2: Audi e-tron 55 quattro (Electric)
- Model: e-tron 55 quattro
- List Price: £71,520
- CO₂ Emissions: 0 g/km
- Fuel Type: Electric
- Tax Year: 2024/25
- Income Tax Band: 40%
- Capital Contribution: £2,500
Results:
- P11D Value: £69,020
- BIK Percentage: 2%
- Annual BIK Value: £1,380.40
- Annual Tax: £552.16
- Monthly Tax: £46.01
- Employer NI: £190.50
Analysis: The electric e-tron benefits from the 2% BIK rate, making it extremely tax-efficient despite its high list price. The £2,500 capital contribution further reduces the P11D value.
Example 3: Audi Q5 55 TFSI e quattro (Plug-in Hybrid)
- Model: Q5 55 TFSI e quattro
- List Price: £58,735
- CO₂ Emissions: 45 g/km
- Electric Range: 34 miles
- Fuel Type: Plug-in Hybrid
- Tax Year: 2024/25
- Income Tax Band: 20%
- Capital Contribution: £1,000
Results:
- P11D Value: £57,735
- BIK Percentage: 11%
- Annual BIK Value: £6,350.85
- Annual Tax: £1,270.17
- Monthly Tax: £105.85
- Employer NI: £875.42
Analysis: The Q5 PHEV demonstrates how plug-in hybrids occupy a middle ground. Its 34-mile electric range qualifies it for an 11% BIK rate, which is significantly better than a pure petrol Q5 (which would be 32-34%) but higher than a full EV.

Expert Tips to Minimise Your Audi Company Car Tax
1. Choose the Right Powertrain
- Electric Models: Audi’s e-tron range qualifies for the 2% BIK rate through 2024/25, offering massive savings. The e-tron 50 starts at £60,990 but costs just £487.92 annually in tax for a 40% taxpayer.
- Plug-in Hybrids: Models like the A6 TFSI e or Q5 TFSI e can achieve 11-14% BIK rates if they meet the 30+ mile electric range threshold.
- Avoid High-Emission Petrols: A petrol A8 with 200g/km CO₂ incurs a 37% BIK rate – nearly double that of an equivalent diesel meeting RDE2 standards.
2. Time Your Vehicle Change
- New BIK rates are announced in advance. If rates are increasing, consider changing your car before the new tax year.
- The 2024/25 rates were published in 2022, allowing for long-term planning.
- Electric vehicle rates remain at 2% until 2024/25, then increase by 1% annually to 2027/28.
3. Maximise Capital Contributions
You can make a capital contribution of up to £5,000 to reduce the P11D value. For a £50,000 Audi:
- £5,000 contribution reduces P11D to £45,000
- At 30% BIK, this saves £1,500 in annual BIK value
- For a 40% taxpayer, that’s £600 less tax per year
4. Consider Optional Extras Carefully
Any optional extras fitted at first registration increase the P11D value. For example:
| Optional Extra | Cost | Impact on Annual Tax (30% BIK, 40% taxpayer) |
|---|---|---|
| Panoramic sunroof | £1,200 | £144 |
| Bang & Olufsen sound system | £850 | £102 |
| Virtual cockpit plus | £500 | £60 |
| Matrix LED headlights | £1,500 | £180 |
5. Utilise Salary Sacrifice Schemes
Many employers offer salary sacrifice schemes where you give up part of your salary in exchange for a company car. This can:
- Reduce your income tax liability by lowering your taxable income
- Potentially move you into a lower tax band
- Provide National Insurance savings for both you and your employer
According to research from the Institute of Chartered Accountants, salary sacrifice can reduce the effective cost of a company car by 30-40% compared to personal ownership.
6. Monitor Real-World Electric Range
For plug-in hybrids, the official electric range determines the BIK rate. However:
- Real-world range is often 20-30% less than the official WLTP figure
- HMRC may challenge rates if the vehicle isn’t charged regularly
- Keep charging records to demonstrate compliance
7. Consider Used Company Cars
While most company cars are new, some employers offer used vehicles. The tax calculation changes:
- P11D value is based on the car’s market value when first made available
- For cars over 4 years old, the market value is used instead of original list price
- This can significantly reduce tax for premium models that depreciate quickly
Interactive FAQ: Your Audi Company Car Tax Questions Answered
How does Audi’s quattro all-wheel drive system affect company car tax?
Audi’s quattro system itself doesn’t directly impact company car tax calculations. However, it can have indirect effects:
- Increased P11D Value: quattro models typically cost £1,500-£3,000 more than equivalent front-wheel drive models, increasing the P11D value.
- Higher CO₂ Emissions: The additional weight and mechanical complexity of quattro can increase CO₂ emissions by 5-15g/km, potentially moving the car into a higher BIK band.
- Performance Impact: Some high-performance quattro models (like the S and RS lines) have significantly higher CO₂ emissions due to their powerful engines.
For example, the A4 35 TDI (FWD) has CO₂ emissions of 114g/km (26% BIK), while the A4 35 TDI quattro emits 124g/km (28% BIK).
What’s the difference between P11D value and the price I actually pay for the car?
The P11D value is specifically defined for tax purposes and often differs from the actual purchase price:
| Component | Included in P11D? | Notes |
|---|---|---|
| Manufacturer’s list price | Yes | Before any discounts |
| VAT (20%) | Yes | Always included |
| Delivery charges | Yes | Standard delivery fees |
| First registration fee | Yes | Included in initial cost |
| Optional extras fitted at first registration | Yes | Even if added later but before first use |
| Road tax (VED) | No | Not part of P11D calculation |
| Insurance | No | Separate running cost |
| Fuel costs | No | Not included in benefit calculation |
| Discounts or fleet pricing | No | P11D uses list price, not actual price paid |
| Capital contribution (up to £5,000) | Deducted | Reduces the P11D value |
For example, you might negotiate a £3,000 discount on a £40,000 Audi A4, paying £37,000. However, the P11D value remains £40,000 (plus VAT) for tax purposes.
How does the 4% diesel supplement work, and does it apply to all Audi diesel models?
The 4% diesel supplement applies to all diesel vehicles unless they meet the RDE2 (Real Driving Emissions Step 2) standard. For Audi models:
- Pre-September 2019: Most Audi diesel models registered before September 2019 do NOT meet RDE2 and incur the 4% supplement.
- Post-September 2019: Newer Audi diesel models (particularly those with SCR and DPF systems) typically meet RDE2 and avoid the supplement.
- Impact: The supplement increases the BIK percentage by 4 percentage points, up to a maximum of 37%.
Examples:
- An Audi A6 40 TDI (130g/km) normally has a 30% BIK rate. Without RDE2 compliance, this increases to 34%.
- For a 40% taxpayer, this adds £806.40 to the annual tax bill (based on a £50,000 P11D value).
To check if your Audi diesel meets RDE2, consult the Vehicle Certification Agency or your Audi dealer.
Can I claim back VAT on my Audi company car?
VAT recovery on company cars depends on how the vehicle is used:
If the car is used exclusively for business:
- You can reclaim 100% of the VAT on the purchase price
- You can reclaim 100% of the VAT on running costs (fuel, servicing, etc.)
If there’s any private use (including home-to-work travel):
- You can reclaim 50% of the VAT on the purchase price
- For fuel, you can either:
- Reclaim all VAT and pay a fuel scale charge (currently £27,800 × BIK% for 2024/25)
- OR reclaim VAT only on business mileage (with detailed records)
- You can reclaim 100% of VAT on servicing and repairs
Special Cases:
- Pool Cars: If the Audi is a pool car (used by multiple employees, not kept overnight, no private use), you can reclaim 100% VAT.
- Electric Vehicles: Same rules apply, but the lower BIK rates often make VAT recovery more valuable.
Always consult with a VAT specialist, as HMRC’s rules are complex. The GOV.UK VAT on motoring expenses guide provides official guidance.
How does company car tax work if I have my Audi for only part of the tax year?
If you don’t have the company car for the full tax year, the BIK value is pro-rated based on the number of days you had the car. The calculation is:
Pro-rated BIK = (Annual BIK Value ÷ 365) × Number of Days Available
Examples:
- You receive an Audi A6 (£50,000 P11D, 30% BIK) on 1 October 2024. You’ll have it for 184 days of the 2024/25 tax year.
Annual BIK = £15,000
Pro-rated BIK = (£15,000 ÷ 365) × 184 = £7,556.16 - You return your Audi Q5 on 31 January 2025. You had it for 212 days.
Annual BIK = £18,000 (assuming £60,000 P11D, 30% BIK)
Pro-rated BIK = (£18,000 ÷ 365) × 212 = £10,479.45
Important Notes:
- The day the car is first made available counts as a full day
- The day it’s returned doesn’t count
- If you have multiple company cars in a year, each is calculated separately
- HMRC provides a detailed guide on pro-rata calculations
What happens to my company car tax if I get promoted and move into a higher tax band?
Your company car tax is calculated based on your income tax band at the end of the tax year (5 April). If you’re promoted during the year:
- Mid-Year Promotion: If you move from basic rate (20%) to higher rate (40%) on 1 November, you’ll pay:
- 20% on the BIK value for the period 6 April – 31 October (209 days)
- 40% on the BIK value for the period 1 November – 5 April (156 days)
- Calculation: For an Audi with £10,000 annual BIK value:
First period: (£10,000 × 209/365) × 20% = £1,145.21
Second period: (£10,000 × 156/365) × 40% = £1,712.33
Total tax = £2,857.54 (equivalent to 28.58% effective rate) - Practical Impact: The tax is collected through PAYE, so your monthly deductions will increase after the promotion. HMRC will automatically adjust your tax code.
- Planning Opportunity: If you’re near the threshold, consider timing a car change to avoid being taxed at the higher rate for a full year.
The HMRC employer guide provides detailed examples of how tax codes are adjusted for changes in circumstances.
Are there any exemptions or reductions for low-emission Audi models?
Yes, several exemptions and reductions apply to low-emission Audi models:
1. Electric Vehicles (e-tron models):
- 2% BIK rate for 2024/25 (increasing to 3% in 2025/26 and 4% in 2026/27)
- 100% first-year capital allowance (writing down allowance)
- No diesel supplement
- Exempt from London Congestion Charge and ULEZ
- Eligible for 100% electric vehicle grant (where available)
2. Plug-in Hybrid Vehicles (TFSI e models):
- BIK rates as low as 8% for models with 70+ mile electric range
- Reduced rates for 30-69 mile range (11-14%)
- Potential for 100% first-year allowance if CO₂ <50g/km and electric range >130 miles
- Lower fuel benefit charges if charged at work
3. Ultra-Low Emission Petrol/Diesel Models:
- Models with CO₂ ≤50g/km qualify for reduced BIK rates
- Audi’s mild hybrid (MHEV) models often achieve 10-20g/km lower CO₂ than equivalent non-hybrids
- Diesel models meeting RDE2 standards avoid the 4% supplement
4. Special Cases:
- Pool Cars: If an Audi is used as a pool car (no private use, not kept overnight), it’s exempt from BIK tax entirely.
- Classic Cars: Audi models over 15 years old with CO₂ ≤100g/km may qualify for reduced rates.
- Disabled Drivers: Special rules apply if the car is adapted for a disabled employee.
For the most current information, refer to the HMRC advisory fuel rates and plug-in grant guidance.
