One of the areas that raises the most questions and simultaneously creates optimization opportunities for companies subject to Estonian corporate income tax is the leasing of passenger cars. The new legal regime removes the previous tax restrictions for companies.
In the traditional tax system, entrepreneurs financing motor vehicles through leasing face a rigid statutory barrier: a limit of PLN 100,000 for combustion-engined vehicles and PLN 150,000–200,000 for vehicles with other engines. Any excess above these amounts cannot be considered a tax-deductible expense, drastically increasing the real cost of investing not only in premium vehicles but also in economy-class cars. The transition to the Estonian CIT completely eliminates these limits, as this tax formula eliminates the concept of tax-deductible expenses in the traditional sense. The tax base becomes the generated profit distributed to partners and specific categories of transfer or consumption expenses, which means that the full value of the lease payment and depreciation charges impact the financial result without "cutting" costs.
Balance sheet classification as a new foundation for settlements
The key to correctly accounting for a lease agreement in the Estonian Corporate Income Tax (CIT) is the strict subordination of settlements to accounting law. The Accounting Act becomes the sole guide for accountants at this point. Agreements that were classified as operating leases for income tax purposes often must be recognized as finance leases in the accounts of taxpayers settling their Estonian Corporate Income Tax (CIT). This is because the criteria specified in Article 3, Section 4 of the Accounting Act are much more stringent than tax regulations. As a result, the company must enter the leased asset in its fixed asset register and depreciate it according to balance sheet principles, dividing the lease payment into principal and interest. Any mistake at this stage, including maintaining a simplified accounting treatment of operating leases without meeting the statutory requirements, can result in incorrect accounting records, which poses a direct risk of questioning the accuracy of the net profit calculation.
Mixed Costs and the Hidden Profit Trap
The lack of a monetary limit on cars, however, does not mean complete freedom. The main sticking point in relations with tax authorities is the manner in which vehicles are used. If a passenger car is used for both business and private purposes of shareholders or employees, we are dealing with a so-called mixed use. In this scenario, the legislature has provided for flat-rate penalties. Exactly half of all expenses related to such a vehicle – including lease payments, insurance, fuel, and maintenance costs – are considered expenses unrelated to business activity or income from hidden profits. This half of the value is subject to Estonian corporate income tax (CIT), which is 10% for small taxpayers and 20% for other entities. The only way to avoid this taxation is to maintain detailed records of vehicle mileage and establish strict regulations excluding any private use, which in business practice can be extremely difficult to defend against the tax authorities.
Net or gross tax base?
One of the most complex and contentious technical issues is determining whether the taxable basis for the aforementioned 50 percent of mixed expenses is the net or gross amount resulting from the leasing invoice. In this regard, tax authorities and administrative courts have adopted a uniform, albeit restrictive, stance.
The basis for lump-sum taxation on corporate income is the expense in financial terms, meaning the real economic burden borne by the company. For taxpayers who are entitled to a 50% deduction of value added tax, the undeducted half of the VAT increases their balance sheet expense. Consequently, when calculating the Estonian CIT tax base for mixed expenses, the net amount plus the portion of VAT that was not deductible under VAT regulations should be taken into account. This means that exactly half of the sum of the net amount and undeducted value added tax is subject to taxation at a rate of 10 or 20 percent, which increases the effective tax burden of the leasing transaction.
Transition to the new system during the contract period
Particular caution should be exercised when a company decides to switch to Estonian CIT during the term of a long-term lease agreement. On the day preceding the transition to the new tax regime, financial statements must be prepared and a preliminary adjustment must be settled. If the agreement was considered an operating lease for tax purposes but a financial lease for balance sheet purposes, temporary differences between the tax and carrying amounts of the assets arose in the period before the transition to Estonian CIT. These differences must be identified and properly accounted for to prevent double taxation of the same financial flows or the complete omission of certain costs. Taxpayers must also remember that any modifications to lease agreements after the transition to Estonian CIT, such as assignments, shortening the contract period, or changing the repayment schedule, require reassessment for their impact on the net financial result, which has been the core of the entire accounting system since the transition to the Estonian tax regime.
