What Does a Tax Attorney Do?

Tax attorney roles and responsibilities

A tax attorney is a lawyer who specializes in tax law and helps individuals and businesses deal with legal tax issues. That includes representing clients in disputes with the IRS, advising on complicated tax situations and helping resolve serious tax problems.

Unlike accountants or tax preparers, a tax attorney can give legal advice and represent you in court if needed. They specialize in situations where taxes overlap with legal risk.

According to Concepción, types of tax problems that would require a tax attorney include:

• Domestic and international structuring or restructuring of businesses, investments or ownership arrangements
• Reporting of international assets when the ownership structure or income is ambiguous
• Contract analysis
• Restructuring of an investment or a business
• Any issue that requires a legal analysis, such as when there is a question of law
• High-stakes audits or contested IRS positions
• Significant penalties or assessments
• Allegations of tax fraud, tax evasion or willful noncompliance
• Criminal tax investigations or referrals
• Tax issues tied to litigation, divorces, estates or business sales

How do tax attorneys assist in legal tax matters?

Tax attorneys can act as a legal buffer between you and the IRS. Your tax attorney can handle all communication and prevent any misstatements that could make your situation worse.

Additionally, they draft and review legal documents related to taxes, such as settlement agreements, tax opinions or closing agreements. And in more serious situations, such as tax fraud or evasion allegations, a tax attorney can provide legal representation.

Tax planning and compliance

Tax attorneys don’t just deal with tax problems after they happen. They can help you plan ahead and think through the tax impact of major financial decisions before they occur. This way, you can legally minimize your taxes and avoid triggering scrutiny and audits later.

Tax attorneys also help ensure compliance by advising you on filing requirements, reporting rules and documentation standards at the federal, state and local levels. Tax compliance is especially important if you own a business or have estates where mistakes can be expensive.

When tax laws change, a tax attorney can also explain how those changes affect your existing tax strategies and what adjustments you may need.

When to hire a tax attorney

Not everyone needs a tax attorney. But there are certain situations where their legal expertise could be helpful:

• You’re facing IRS legal action: Audits, tax liens, IRS levies, wage garnishments or court proceedings may warrant legal representation.
• You owe a large amount in back taxes: If you owe back taxes, a tax attorney can help you assess legal risks and negotiate options like settlements.
• You’re under criminal investigation for tax issues: If the IRS alleges tax evasion or fraud, you’ll want legal protection as well.
• Your case involves complex tax law questions: When the interpretation of federal or state tax law affects your liability or exposure, you should seek a tax expert.
• You’re dealing with business or payroll tax problems: Employment taxes, trust fund recovery penalties or business closures often come with legal consequences.

On the other hand, you may only need a certified public accountant (CPA) or enrolled agent in these scenarios:

• Filing routine individual or business tax returns
• Correcting minor errors or responding to standard IRS notices
• Negotiating with the IRS or entering into a payment plan if the tax due is not significant
• Managing payroll taxes or bookkeeping
• Setting up payment plans for relatively straightforward tax balances

Tax attorney vs. CPA

Knowing the difference between a tax attorney and CPA can help you decide which one to call when you need tax assistance.

Tax attorney vs. CPA key differences

A tax attorney is a lawyer trained in tax law who provides legal advice and representation. A CPA is an accounting professional who focuses on preparing tax returns, managing financial records and ensuring compliance from an accounting perspective.

The key difference is that tax attorneys can represent clients in court and provide attorney-client privilege. CPAs focus more on tax preparation, reporting and financial accuracy.

Tax attorney vs. CPA: How to decide which to hire

Hiring a CPA typically makes sense if you need help with routine tax filing, bookkeeping and basic tax planning. A tax attorney is a better choice for disputes, audits, legal questions or situations involving tax relief, penalties or enforcement actions.

How to choose between a CPA and a tax attorney

Often, it’s not an either/or decision on whether to hire a tax attorney or CPA. In more complicated tax situations, you may need to work with both.

Areas of expertise in tax law

Tax law covers a wide range of specialized areas, and many tax attorneys focus on specific niches based on their training, experience and the types of clients they serve.

Specialized areas within tax law

The specialized areas within tax law typically include:

1. Corporate tax: Advising corporations on tax compliance, structuring, mergers and acquisition and minimizing tax exposure under federal and state law
2. International tax: Handling cross-border income, foreign tax credits, transfer pricing and reporting requirements for overseas assets and income
3. Partnership tax: Managing tax issues related to partnerships, LLCs and pass-through entities, including allocations, distributions and compliance
