VAT registration UAE businesses frequently stumble on one specific issue: how to recover input tax on costs that serve both taxable and non-business or exempt purposes. Getting this wrong is one of the most common reasons the FTA raises queries during a VAT audit, and it directly affects how much you can legitimately claim back on every VAT return. This guide breaks down how mixed-use input tax recovery actually works, with practical examples relevant to UAE businesses.
What counts as a "mixed-use" cost for VAT purposes?
A mixed-use cost is any expense that relates partly to activities where you can recover VAT (taxable supplies at 5% or 0%) and partly to activities where you cannot (exempt supplies, or non-business/private use). Common examples include:
- Office rent and utilities for a business that also earns exempt rental income from residential property
- Company vehicles used for both business trips and personal errands
- Mobile phones, laptops, or software licences shared between directors' personal use and business use
- Marketing or admin overheads covering both a taxable trading division and an exempt financial services arm
If a cost relates wholly to taxable supplies, input tax is fully recoverable. If it relates wholly to exempt supplies or private use, it is not recoverable at all. The complexity — and the risk of errors in VAT return filing — arises only with costs that straddle both categories.
How do you apportion input tax correctly?
The standard method
The UAE’s standard method is the inputs-based apportionment method, not the output-based method. First, directly attribute input tax to the relevant activities: input tax wholly related to recoverable supplies is fully recoverable, while input tax wholly related to exempt supplies or non-business activities is not recoverable. Input tax that cannot be directly attributed is treated as residual input tax.
Under the standard method, the recovery percentage is calculated as:
Wholly recoverable input tax ÷ (Wholly recoverable input tax + Wholly non-recoverable input tax) × 100
The resulting percentage, rounded to the nearest whole number, is applied to the residual input tax for that tax period. Input tax specifically blocked under UAE VAT rules must be excluded from this calculation.
Alternative methods
Where the standard inputs-based method does not produce a fair and reasonable result, certain eligible businesses may apply to the FTA for approval to use a special apportionment method. The FTA guide describes methods including:
Outputs-based method: based on the value of taxable supplies compared with total supplies.
Transaction-count method: based on the number of taxable transactions compared with total relevant transactions.
Floorspace method: based on the allocation of premises used for different activities.
Sectoral method: allocates residual input tax across different business sectors.
These methods are not freely interchangeable options for every VAT-registered business. Eligibility depends on the nature of the business and the conditions prescribed by the FTA. A registrant generally must have been VAT-registered for at least six months to apply for a special method and must demonstrate why the standard method does not give a fair and reasonable result. The method can be used only after FTA approval.
For example, the outputs-based method is available to specified categories such as educational institutions, certain entities conducting non-business activities, financial institutions, insurance companies and local passenger transport providers. Businesses should review the applicable eligibility criteria and obtain approval before applying a special method.
What about VAT on cars, entertainment, and employee costs?
Some input tax is blocked outright regardless of apportionment, because UAE VAT law specifically disallows it. Key blocked categories include:
Motor vehicles available for personal use: Input tax on a motor vehicle is generally blocked where it is available for private use by the business owner or an employee. Exceptions may apply to vehicles used in specified business activities or where the vehicle is not available for private use.
Entertainment expenses: Input tax on entertainment provided to persons who are not employees, such as customers, potential customers, shareholders and other business contacts, is generally not recoverable, subject to the exceptions under UAE VAT law.
Employee-related expenses: Input tax on goods or services provided to employees for their personal benefit is generally blocked, unless the employer is legally or contractually required to provide the benefit, or another prescribed exception applies.
Many businesses mistakenly include these in their recoverable input tax, which overstates refund claims and creates exposure in a future audit. If your bookkeeping doesn't flag these categories separately, your accountant may miss them during VAT return filing — this is a strong argument for proper accounting and VAT support rather than relying on raw bank exports.
How does this affect your VAT return and refund position?
Mixed-use apportionment directly changes the input tax figure you report on your periodic VAT return. Getting it wrong in either direction causes problems:
Over-claiming: Incorrectly recovering input tax may result in an understated VAT liability or an excessive refund claim. The FTA may assess the tax shortfall and impose applicable administrative penalties and other amounts under the relevant rules.
- Under-claiming input tax means you're paying more VAT than legally necessary, quarter after quarter, which adds up over a financial year
If you have already filed VAT returns using an incorrect apportionment calculation, you should assess whether a correction or voluntary disclosure is required under the UAE Tax Procedures rules. The appropriate action depends on the nature and amount of the error and the applicable correction requirements. Do not assume that every apportionment difference automatically requires a voluntary disclosure. Review the affected returns and supporting calculations promptly to determine the correct treatment and any potential penalties.
Frequently Asked Questions
Do all VAT-registered businesses need to apportion input tax?
No. A business generally needs to apportion only where it incurs residual input tax that relates partly to activities allowing VAT recovery and partly to exempt supplies or non-business activities. Input tax that can be directly attributed to taxable or other qualifying recoverable supplies is generally fully recoverable, while input tax directly attributable to exempt supplies or non-business activities is generally not recoverable. Businesses making only taxable supplies generally do not need residual input tax apportionment, although blocked input tax rules still apply.
Can I change my apportionment method mid-year?
A business cannot simply switch to a special apportionment method whenever it considers another method more beneficial. The standard inputs-based method applies unless the FTA approves the use of a special method or a specified recovery percentage. Businesses must follow the approved method and its conditions. Under the standard method, an annual wash-up is also required to reconcile the input tax recovered during the tax year with the annual calculation.
What happens if the FTA disagrees with my apportionment?
The FTA can request supporting calculations and documentation during a review. If they find the method unreasonable or unsupported, they may reassess your input tax recovery, apply penalties, and require you to use a different method going forward. Keeping clear workings for every tax period is essential.
