Why is tax research so important? Because it’s impossible to memorize the entire Internal Revenue Code (IRC) and the way it changes over time. Add to that the regulations and other interpretive rules that are necessary to implement the statutory rules of the IRC, and it can be extremely difficult to find everything you need to effectively communicate your findings to stakeholders. And that’s only federal tax law.
That’s why even experienced tax professionals turn to a comprehensive resource like Bloomberg Tax Research as they go through the steps of the tax research process. Bloomberg Tax Research pairs the proven expertise and perspective of its network of 1,000+ leading tax practitioners in our renowned Tax Management Portfolios with integrated news, in-depth analysis and insights, primary sources, and practice tools to help you understand complex tax topics and make informed decisions.

What is tax research and why is it necessary?
The purpose of tax research is to help you properly define the tax effect or impact of certain tax positions. The results help your company and/or your clients make informed decisions for tax strategies, planning, and compliance. Tax research can also help you prepare for an IRS audit.
Tax research identifies relevant binding and persuasive authorities for a specific point of tax law or issue. For tax issues, this includes legislative, administrative, and judicial authorities.
When you conduct tax research, you’re looking for binding authorities (also known as controlling or mandatory authorities) and persuasive authorities. Binding authorities are anything that a court must follow (such as constitutions, legislation, and some court decisions depending on the jurisdiction) because they bind the court. Persuasive authorities are anything that the court may follow (including some cases, statutes, and regulations, but also opinions, law review articles, and other secondary sources) but does not have to follow.
There’s another categorization as well. Primary sources are source law such as statutes, regulations, and case law. Secondary sources are discussions of source law such as law review articles.
Given all the different sources of information you’ll need for your research, the most efficient way to approach it is to rely on a comprehensive resource that brings together everything you need in one place.
When a complex question comes up, we can start with the code, go to the regulations, build an argument and be able to support and document it – all made possible by the tools within the Bloomberg Tax platform.

How can I conduct tax research if I’m new to the topic or issue?
The first steps in the tax research process are to analyze the available facts, pinpoint the legal issues involved, and formulate an appropriate tax question (or questions) to be researched. But what if you don’t have enough knowledge to be able to identify the specific issues to research?
That’s where it helps to have explanations and analysis from more than 1,000 expert tax practitioners at your fingertips. You can start with an overview of the more general topic in Bloomberg Tax Management Portfolios or Tax Practice Series.
The overview can help you formulate initial keywords and phrases to further explore the topic. Extensive planning points, practical examples, what-if scenarios, and comments by our expert authors help you confidently navigate and understand the issue.
Then, you can find the latest news on the topic from the Daily Tax Report, a comprehensive source for news on federal, state, and international legislative, regulatory, and judicial tax-related developments, including pensions and accounting.

How should I use technology to improve my tax research?
While the internet contains nearly 5 million terabytes of data, you shouldn’t rely on a service like Google for your tax research. That’s because Google doesn’t vet the information it’s indexing. There are no standards for quality and accuracy. There’s also no curation of content to make sure it’s relevant, up to date, and from trusted sources.
