Few things are as certain in life as taxes. Sometimes things don't go as planned. In general, tax matters tend to focus on a few areas for small business and individuals, estate and gift, income, and state and local (including things like property taxes and employment tax). Tax law varies in each jurisdiction and generally having a good CPA or other tax specific professional goes a long way to preventing problems in the first place. However, sometimes, differences can become unavoidable.
Having an advocate to assist in audits, lien and levy processes, collections, appeals, and criminal tax matters is critical. Attorneys can go the distance from beginning of dispute, through administrative hearings and court processes, to appeal as required on a case by case basis.
Additionally, an attorney can integrate your tax and business or estate planning process allowing you to get a bigger picture, minimize taxes, and maximize the amount that you can pass to your family.
