A tax lawyer is a representative of individual persons, businesses, and organizations in matters that relate to taxes. These lawyers are knowledgeable about tax law and often provide advice to their clients on how to deal with their financial issues in a way that is consistent with local and national tax rules. They may also help individual persons and businesses in case when an error has already been made in a tax-related situation.

One kind of tax lawyer is called an income tax lawyer. This sort of lawyer helps tax payers who have to pay taxes to a local or national agency depending on their income amounts. He may advise a taxpayer on tax law and check if he is paying the correct amount of money, assisting him with following the law requirements related to deductions and credits as well. An income tax lawyer may be especially helpful when a person has quite a few income sources or is self-employed, and has income amounts that might be hard to prove or keep record of. Now and then income tax lawyers do more than just advise taxpayers; an income tax lawyer may supply representation when a tax agency makes a decision to look into a taxpayer's return.

Some tax lawyers may work for law companies or start their own law offices. Some may be hired by government agencies while others choose to work for private institutions. When lawyers work for government agencies and businesses with private or public owners, they may either work as salaried employees or called on for occasional consultations.
