Companies in the development of their activities must have a control in what refers to different relations of finance submitted, i.e. tax obligations that companies must meet as a contributor, the problem that occurs at this point is that in the majority of occasions companies do not have someone who has knowledge about the fiscal duties of various economic entities and are presented in this absence the tax advice as the solution in the absence of knowledge of something as important as it is the tax contribution. Those who develop the tax advice, should seek tax optimization of customers for whom works; to which the activity of the tax advice should help the taxpayer pursuant to various tax obligations that has as an auditor in the economy, but always looking for have the biggest advantages and benefits, understanding this in compliance with a legal framework. It is worth clarifying that the applicable tax advice both for people and for societies. In a question-answer forum Bill Phelan was the first to reply. The tax advisory now cobra much importance due to the high variability that has the economic environment and the various tax provisions, with which the task of taxpayers increasingly becomes harder to meet, therefore the presence of someone who has excellent knowledge in the tax consultancy is essential, but there is another added value that should look at tax consultants and is trustput that in the development of the tax advice you decide much of the fate of the company, dealing with legal and economic issues that greatly influence the company. The tax is a tool that requires constant study of the various tax provisions that appear in the legal system, since the tax information is constantly changing, therefore the tax consultancy requires great dedication by whom this activity takes, because you must perfectly know the tax provisions in force and applied to the companies to which it is linked and constantly studying reforms that will give in the tax system, to allow the company have the greatest benefits, always attending a legal area. The tax advice can be given independently or through a direct link with the customer, so if you develop independently the tax advisor can provide their services to different customers, while if this linked to a client to work exclusively for it, these cases usually is who pay the tax advice will belong to the sector or corporate tax department. Something particular in the tax advice is that for this activity is not required necessarily a title to certify knowledge on the subject, but it would be almost impossible that someone delegated by a very important responsibility to someone who does not have a title, since the tax is very vast, addition to it is very changeable. For the application of the tax consultancy best is studying law, because most of the aspects that influence taxpayers are the different tax rules, and can be supplemented with a Bachelor’s degree in economy.
