    Accounting profit in spainish legislation
    2019-05 - Aldeia, Susana
    The main goal of this paper is to study the accounting profit in the spanish jurisdiction. For this purpose the accounting profit and its integration in accounting and tax legislation of Spain were analized. In accounting terms the study focus on the Comerce Code and Accounting law. On the one hand, the assumption of accounting profit in corporate income tax law and the significance of its economic periodization were investigated. The results show that the spanish Comerce Code recognizes a relevent role to accounting profit. It also recognizes that it is very important for the companies to give financial information about their economic lives. It establishes specific issues, such as the elements of the annual accounts, and how the net profit should be determined. On the other hand, an effort was made to understand and analyse the relevence of the periodization of the corporations´ economic life. It happens having as underlying the accrual basis' accounting principle. This may occur due to several economic, financial and legal reasons. Concerning the economic reasons it is necessary to define economic periods for management evaluation and the distribution of the results to the company's owners. Financially, the company has to assure all the financial needs to maintain its activity. In legal terms, it is important to determine tax periods that can establish the tax due by the entity's economic performance. The analysis of article 10 of the spanish corporate income tax law allows us to conclude that the spanish tax legislator recognizes the tax direct valuation method to determine the taxable profit. It means that the net profit determined under accounting rules is used to calculate the taxable basis that will be subjected to pay income tax by the national economic entities.

    2019 - Aldeia, Susana
    The main goal of this paper is to understand how the “true and fair view” concept was incorporated in the Spanish and Portuguese national laws, comparing the national legal dispositions and understanding how this concept was accepted in each of these countries. For this purpose, the business and tax law of both European countries were investigated. In Spain, the Commerce Code (Código de Comercio), the Capital Companies Law (Ley de Sociedades de Capital), the Accounting law (Plan General de Contabilidad) and the Corporate Income Tax Law (Ley del Impuesto sobre Sociedades) were studied. In Portugal was made an analysis of the Code of Commercial Companies (Código das Sociedades Comerciais), the Securities Code (Código dos Valores Mobiliários), the Accounting law (Plano Oficial de Contabilidade and Sistema de Normalização contabilística) and the Corporate Income Tax Law (Código do Imposto sobre o Rendimento das Pessoas Coletivas). The results show that the true and fair view concept was incorporated by both national laws, mainly because as member states of the European Union they were obliged to integrate it. This integration occurred in both business and tax law. The business legislation has a general understanding of the concept as an overriding principle, being the accounting principles simple means to reach it. In the corporation income tax law, this concept is implicitly recognized in both laws by inherent acceptance of generally accepted accounting principles under Articles 10.3 of the Ley del Impuesto sobre Sociedades and 17.3 of the Código do Imposto sobre o Rendimento das Pessoas Colectivas.

The accounting legal framework can represent consequences in the tax sphere. The manager has two tax options in the personal income tax domain, according to the simplified regime and the organised accounting system. The second option implies that workers have an accountant to certify the activity accounts. In the social security domain, the law foresees a lot of legal obligations that are of frequent accomplishment, including the social security payment. Each scope has specific requirements that need to be observed and needs substantial knowledge that marketing people sometimes do not have, thus, it is frequent to recur to an accountant service to get help. This decision represents the increase of the context costs to the employee. The research of this case study evidences how the Portuguese tax system is complex and the difficulties the self-workers can feel when making-decision to develop the activity on their one.
