Tax Publications
If we talk about tax tools, there is one in particular, but we cannot leave aside the resolutions and unique regulatory decrees that support us with the normative bases in tax decisions. Now, just as the doctor has his vademecum, we accountants can also say that we have our “Tax Vademecum” which is nothing more and nothing less than the tax statute, I invite you to download the latest version of this given by the secretary of the senate, it does not come with concordances, but that is the challenge to take the document and unravel it to review its changes from one year to the next.
But if you want to go further, I invite you to look for the tax tools offered by the American government, which are completely free offered by the IRS (internal revenue services). In this link you will find a series of tools in Spanish if you want to explore the North American tax system.
