Are You an Expat in Portugal Considering Buying a Company Car? Here’s What You Need to Know

Before you make that decision, it’s essential to understand which vehicle type offers the best tax advantages under Portugal’s tax code.

From autonomous taxation to VAT deductibility, the kind of car you choose — electric, hybrid, or thermal — can significantly impact your company’s tax bill.

Portugal’s tax framework rewards businesses that invest in green fleets, while imposing higher tax burdens on traditional petrol and diesel vehicles. And if you’re running a small or medium-sized enterprise (SME), these tax considerations aren’t just important — they’re strategic.

Portuguese Corporate Taxation for SMEs in 2025

As of January 1, 2025, the standard Corporate Income Tax (CIT) rate applicable in mainland Portugal is 20%. This rate applies to corporations engaged in commercial, industrial, or agricultural activities, as well as branches of permanent establishments of non-resident entities.

Micro and small to medium-sized enterprises (SMEs) benefit from a preferential tax treatment, with a reduced 16% tax rate for their taxable income up to EUR 50,000. Any income exceeding this initial threshold is then subject to the standard 20% rate.

Autonomous taxation, or Tributação Autónoma, is a distinct tax applied to specific costs and expenses incurred by corporate taxpayers in Portugal. It is levied independently, meaning it is due even if the company reports a tax loss for the fiscal year. This makes it a crucial consideration in financial planning, as it represents a fixed cost that tax losses cannot offset.

The purpose of autonomous taxation is to disincentivise specific types of expenditures that tax authorities deem to be potentially ambiguous and not linked to generating taxable income or maintaining the production source, but rather remunerating in kind their employees, directors or shareholders. It aims to discourage “excessive” or non-essential business spending. It is payable in addition to any Corporate Income Tax that may be due.

2025 Autonomous Taxation Rates for Company Vehicles

For 2025, autonomous taxation rates for specific vehicles have seen slight reductions, and the acquisition value thresholds for each tax bracket have increased. These rates apply to expenses associated with light passenger vehicles, light commercial vehicles, and motorcycles.

Plug-in Hybrids — Autonomous tax rates according to acquisition cost

Up to 37,500: 3%

Up to 45,500: 8%

Excess of 45,500: 15%

Other vehicles — Autonomous tax rates according to acquisition cost

Up to 37,500: 8%

Up to 45,500: 25%

Excess of 45,500: 32%

Battery Electric Vehicles — Autonomous tax rates according to acquisition cost

Up to Euro 62,500: Exempt

In excess of Euro 62,500: 10%

The tax basis in the expense related to each vehicle is its depreciation per accounting standards. Please note that the highest depreciation rate allowed per the Portuguese Corporate Tax Code is 25%.

For newly established businesses, including SMEs, a highly beneficial measure is in place for the 2025 fiscal year: the standard 10-percentage point increase in autonomous tax rates, typically triggered by a company reporting a tax loss, will not apply if the tax loss occurs in the fiscal year of the company’s commencement of activity or in one of the two subsequent fiscal years. This provision offers critical relief to new businesses during their initial, often less profitable, operational period, mitigating financial risk and encouraging new business formation in Portugal.

The autonomous taxation rates primarily apply to “light passenger vehicles, light commercial vehicles and motorcycles”. While explicit legal definitions are not provided in the available material, these classifications generally align with vehicle registration categories.

SMEs should consult official vehicle registration documents and, if in doubt, seek clarification from a tax advisor to ensure correct classification for tax purposes.

The differentiated and significantly lower autonomous taxation rates for PHEVs, coupled with a full exemption for BEVs, demonstrate a strong governmental policy to accelerate the adoption of electric and hybrid vehicles within corporate fleets.

This policy aligns with environmental sustainability goals and offers a powerful financial incentive for businesses to choose greener vehicles. The subtle nature of the rate and threshold changes means that while some vehicles might fall into a lower percentage bracket, careful financial modelling is necessary to accurately determine the actual tax impact of vehicle choices.

VAT Deductions on Company Cars in 2025

Value Added Tax (VAT), known as Imposto sobre o Valor Acrescentado (IVA) in Portugal, is a consumption tax levied on the value added at each stage of the production and distribution chain for goods and services. Businesses collect VAT from customers on sales and deduct VAT paid on purchases (input VAT), remitting the net difference to the Portuguese Tax and Customs Authority (AT). VAT generates government revenue and aims to ensure an equitable distribution of the tax burden.

Portugal operates a multi-rate VAT system, varying rates by goods/services and region. Certain transactions, such as medical services, education, and specific financial transactions, are exempt from VAT.

For VAT incurred on business expenses, including company vehicles, to be deductible, it must be appropriately documented with a valid invoice or import document. The VAT must be directly related to the company’s taxable business activities. Suppose a company engages in both VAT-deductible and non-deductible activities. In that case, either the direct allocation method or the prorate method must be used to determine deductible VAT.

Portugal continues to offer significant VAT incentives for environmentally friendly vehicles:

Battery Electric Vehicles (BEVs): Companies can claim a 100% VAT deduction on the purchase, import, lease, or conversion of EVs, provided the acquisition cost does not exceed €62,500.

Plug-in Hybrid & Hybrid Vehicles: A 100% VAT deduction is allowed on purchase, import, lease, or conversion, as long as the acquisition cost is €50,000 or less.

Additionally, 100% VAT deduction is permitted on electricity costs for charging both BEVs and Plug-in Hybrid & Hybrid Vehicles.

“Exclusively for Business Use” Criterion

For a company to fully deduct VAT on vehicle-related expenses, the vehicle must, in principle, be used exclusively for the company’s taxable business activities. This criterion implies the vehicle is indispensable for business operations and not available for any personal use. Any demonstrable private use can jeopardise full VAT deduction.

Meticulous documentation is essential to substantiate exclusive business use. This includes detailed logbooks, GPS tracking data, fuel records, maintenance invoices, and clear internal company policies prohibiting or strictly limiting private use.

Lack of documentation can lead to disallowance of VAT deductions during tax audits. If private use is unavoidable, businesses may need to apply a prorate method for VAT deduction, making a portion of the VAT an unrecoverable cost. Non-exclusive use can affect both VAT and CIT deductions.

The 100% VAT deductibility for EVs and PHEVs is a substantial financial incentive. Still, it depends entirely on the stringent “exclusively for business use” criterion.

Strategic Considerations and Recommendations

Fully Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs) offer company fleets the most advantageous tax treatment. This is due to their 100% VAT deductibility (up to specified limits), significant exemptions or discounts on Vehicle Tax (ISV), and, for BEVs, a full exemption from the annual road tax (IUC) and autonomous taxation.

SMEs should conduct a detailed financial analysis encompassing acquisition cost, applicable autonomous taxation, potential VAT recovery, ISV and IUC liabilities, and ongoing operational costs.

Robust record-keeping and documentation are paramount for compliance. To ensure successful VAT recovery, especially for vehicles requiring “exclusive business use,” meticulous records are essential. This includes all original invoices, detailed logbooks or GPS tracking data to prove business mileage, and clear internal company policies on vehicle usage. Lack of proper documentation can lead to disallowance of VAT deductions during tax audits. All tax-related records must be retained for a minimum of 10 years and be readily accessible for inspection by the Portuguese Tax and Customs Authority (AT).

Navigating vehicle imports and associated taxes, specifically ISV (Imposto Sobre Veículos — Vehicle Tax) and IUC (Imposto Único de Circulação — Annual Road Tax), also requires careful attention. Fully Electric Vehicles (BEVs) are entirely exempt from ISV. Plug-in Hybrid Electric Vehicles (PHEVs) and standard hybrids receive substantial discounts (75% and 40%, respectively) if they meet specific electric range and CO2 emission criteria.

General advice for expat-owned SMEs on managing Portuguese tax obligations includes seeking professional advice. Given the complexities and frequent legislative updates in Portuguese tax law, engaging with a qualified local tax advisor specialising in corporate and international taxation is highly advisable. Staying informed and proactive is crucial, as tax laws can change annually.

Conclusion

For 2025, Portugal’s tax framework includes favourable adjustments for company car taxation, particularly benefiting electric and plug-in hybrid vehicles. These benefits include reduced autonomous taxation rates, increased acquisition cost thresholds, and continued strong VAT deductibility. A crucial reinstatement for new expat-owned SMEs is the exemption from increased autonomous tax rates during their first three fiscal years of activity, even if the company incurs tax losses.

For businesses navigating the Portuguese tax landscape, a thorough understanding of these tax provisions is indispensable for optimising fleet costs, ensuring full compliance, and maximising available incentives. Proactive tax planning, involving careful vehicle selection aligned with tax benefits, diligent record-keeping, and consistent consultation with a knowledgeable Portuguese corporate tax specialist, will be key to successfully leveraging the available tax advantages and navigating the complexities of company car taxation.
