I'm Darrin Mish. For 32 years I've practiced federal tax litigation — routine audits, Tax Court cases, and everything in between. If you're facing an IRS issue, here's what you need to know first.
I'm Darrin Mish. Tampa tax attorney, 32 years in, more than $100 million in IRS debt resolved. What follows isn't theory – it's what I've actually watched work.
Most people call looking for a tax law lawyer after the IRS has already taken action. The notice arrived. The levy hit. The lien filed. You're trying to figure out if you actually need an attorney or if you can handle this yourself. The answer depends entirely on what the IRS wants and how much room you have to negotiate.
A tax law lawyer does three things that matter: represents you in disputes with the IRS, negotiates settlements you can't get on your own, and protects you from mistakes that turn manageable problems into financial disasters. Everything else is commentary.
What a Tax Law Lawyer Actually Does
The work breaks into three categories. First, representation in IRS proceedings. This includes audits, collections, appeals, and litigation in Tax Court. Second, negotiation of payment arrangements and debt reduction through offers in compromise, installment agreements, and currently not collectible status. Third, resolution of enforcement actions like wage garnishments, bank levies, and federal tax liens.
Most of the work happens in writing and over the phone. The IRS doesn't do a lot of in-person meetings anymore. Your attorney files powers of attorney, responds to IRS correspondence, and negotiates directly with revenue officers and appeals officers. You stop talking to the IRS. They talk to your attorney.

IRS Disputes and Audit Defense
When the IRS audits you, they're questioning specific items on your return. Deductions, income reporting, business expenses, charitable contributions. They want documentation. A tax law lawyer knows what documentation the IRS will accept and how to present it in a way that closes the audit with minimal adjustment.
You don't need an attorney for simple audits where you have all your records. You do need one when the IRS is proposing significant changes, questioning your filing status, or suggesting fraud penalties. The difference in outcome can be tens of thousands of dollars.
The IRS operates under well-defined primary sources of federal tax law including the Internal Revenue Code and Treasury regulations. A tax law lawyer uses these sources to argue your position. The IRS agent is bound by the same law. When you can point to specific code sections and regulations that support your position, audits resolve faster.
Negotiating Settlements and Payment Plans
The IRS would rather collect something than nothing. That creates negotiating room. But only if you know how to use it.
Offers in compromise let you settle tax debt for less than you owe. The IRS accepts them when they believe it's the most they can collect within the statute of limitations. Your attorney calculates your reasonable collection potential, submits the offer with supporting financials, and negotiates with the offer specialist. The acceptance rate is low because most people submit offers they don't qualify for.
Installment agreements spread payments over time. The IRS will approve most installment agreements under $50,000 without much review. Above that, they want detailed financial statements. Your tax law lawyer structures the payment plan to fit your actual budget while satisfying IRS requirements.
Currently not collectible status stops collection when you can't pay anything. The IRS verifies your income and expenses, then shelves your case. Interest and penalties continue accruing, but enforcement stops. Your attorney proves financial hardship with documentation the IRS will accept.
When You Actually Need a Tax Law Lawyer
You need representation when the IRS proposes adjustments over $10,000, when they're threatening criminal penalties, or when they've already started enforcing collection. Below that threshold, you can often handle it yourself or use a CPA. Above it, the cost of mistakes exceeds the cost of representation.
Collection Enforcement Actions
The IRS has broad collection powers. They can garnish wages, levy bank accounts, and seize assets without going to court first. When they've issued a final notice of intent to levy, you have 30 days to respond before enforcement begins. A tax law lawyer can request a collection due process hearing, which stops enforcement and gives you time to negotiate.
IRS wage garnishments take a significant portion of each paycheck until the debt is paid. The IRS leaves you with a small exemption based on filing status and dependents. Everything else goes to them. Your attorney can release the levy by negotiating an installment agreement or proving financial hardship.
Bank levies are one-time seizures. The IRS freezes your account for 21 days, then takes the balance. Unlike wage garnishments, they don't continue. But the IRS can issue multiple levies. Your tax law lawyer releases the levy and prevents future ones by resolving the underlying debt.

Complex Tax Situations
Certain situations require specialized knowledge. Business tax debt, international reporting requirements, trust fund recovery penalties, and innocent spouse claims all involve complex rules and high stakes.
Trust fund recovery penalties make business owners personally liable for unpaid payroll taxes. The IRS can assess these penalties against anyone responsible for paying the taxes who willfully failed to do so. A tax law lawyer challenges the penalty by proving you either weren't responsible or the failure wasn't willful. The burden of proof is on the IRS, but they win most of these cases without proper representation.
Innocent spouse relief protects you from liability for your spouse's tax errors. You must prove you didn't know about the understatement, had no reason to know, and would suffer hardship if held liable. The IRS denies most innocent spouse requests on first submission. Your attorney appeals and presents evidence at a hearing.

|---|---|---|
| Simple audit with records | Yes | Proposed changes over $10,000 |
| Installment agreement under $25,000 | Yes | Multiple prior agreements or defaults |
| Offer in compromise | Rarely | Always (acceptance rate under 25%) |
| Wage garnishment release | Sometimes | IRS rejected your request |
| Trust fund penalty | No | Always (personal liability at stake) |
| Tax Court litigation | No | Always (rules of evidence apply) |
How to Choose the Right Tax Law Lawyer
Not all tax attorneys handle IRS controversy work. Many focus on tax planning, business structuring, or estate planning. You need someone who regularly represents clients before the IRS. That's a specific skillset.
Experience and Practice Focus
Ask how many IRS cases they handle per year. The answer should be in the dozens, not the single digits. Ask what percentage of their practice is IRS controversy work. You want someone who does this full-time, not occasionally.
Geographic location matters less than you'd think. Most IRS work happens remotely. But local knowledge helps when dealing with specific IRS offices and revenue officers. A Florida tax attorney knows the Jacksonville and Tampa IRS offices. That can move cases along faster.
Check their background. Law school doesn't teach much tax procedure. Most tax attorneys learned by working at firms that specialize in it or at the IRS itself. Former IRS attorneys understand how the agency thinks and what arguments work. That experience is valuable.
Fee Structures and Cost
Tax law lawyers typically charge hourly rates or flat fees for specific services. Hourly rates for experienced tax attorneys run $300 to $500 per hour in most markets. Flat fees for offers in compromise typically range from $3,000 to $7,500 depending on complexity. Audit representation might cost $2,500 to $10,000.
Be skeptical of unusually low fees. The work takes time. If someone quotes significantly below market rates, they're either inexperienced or planning to hand your case to a junior associate. Ask who will actually handle your case.
Most tax attorneys offer free initial consultations. Use that time to explain your situation and ask specific questions about their approach. A good attorney will tell you whether you need representation or can handle it yourself. IRS forgiveness programs have specific qualification requirements. Your attorney should know immediately if you're a candidate.

Common Tax Problems That Require Legal Help
Some problems require representation almost immediately. Others give you time to explore options. Understanding the difference helps you act appropriately.
Unfiled Tax Returns
The IRS can file substitute returns for you if you don't file. These substitute for return assessments typically show much higher tax liability than what you'd actually owe. They don't include deductions you're entitled to. They use single filing status regardless of your actual status. They create massive tax bills that may be entirely inaccurate.
Your tax law lawyer files original returns to replace the substitutes. The IRS recalculates your liability based on actual income and deductions. This often reduces the debt by 40% to 60%. But you need accurate records going back years. Your attorney works with forensic accountants to reconstruct income when records are missing.
Criminal Tax Investigations
If the IRS Criminal Investigation Division contacts you, stop talking immediately and call a tax law lawyer. These investigators aren't trying to collect taxes. They're building a criminal case. Anything you say will be used against you.
Most criminal tax cases involve willful tax evasion or filing false returns. The government must prove intent. A tax law lawyer protects your rights during the investigation and negotiates with prosecutors to avoid indictment when possible. If charges are filed, they coordinate with criminal defense counsel on trial strategy.
Criminal tax exposure is rare compared to civil collection cases. But when it happens, the consequences include prison time. Don't try to handle this yourself.
Business Tax Debt and Payroll Tax Issues
Business tax debt accumulates faster than personal tax debt. Monthly payroll tax deposits, quarterly estimated taxes, and annual returns all create compliance obligations. Miss any of them and the debt compounds quickly.
The IRS prioritizes payroll tax debt. These are trust fund taxes collected from employees. The IRS views failure to remit them as theft from employees and the government. They're aggressive about collection and quick to pursue trust fund recovery penalties against responsible persons.
A tax law lawyer can negotiate payment plans for business tax debt, but the IRS requires current compliance. You must file all returns and stay current on ongoing deposits. Without that, no payment plan. Your attorney helps you get compliant while negotiating on past debt.
Tax Law Research and Legal Authority
Understanding tax law requires access to primary and secondary sources. The Internal Revenue Code contains all federal tax statutes. Treasury regulations interpret and implement the code. Revenue rulings and revenue procedures explain IRS positions on specific issues. Case law from Tax Court and federal courts establishes precedent.
Your tax law lawyer uses specialized research tools to analyze your situation. Tax law databases like Checkpoint and Bloomberg Tax provide comprehensive access to primary sources, legislative history, and practice aids. Understanding how to navigate these resources separates effective tax attorneys from those who wing it.
Secondary sources like treatises and practice guides provide analysis and strategy. Tax law research guides compiled by law libraries help practitioners find relevant authority quickly. Your attorney should be able to cite specific code sections and cases that support your position.
How Tax Law Applies to Your Case
Every tax controversy involves applying general law to specific facts. The Internal Revenue Code provides the framework. Treasury regulations fill in details. Revenue rulings show how the IRS interprets the law. Court cases establish boundaries on IRS authority.
Your tax law lawyer analyzes your situation against this legal framework. They identify arguments the IRS is required to accept based on controlling authority. They distinguish unfavorable precedent. They know which arguments work with which IRS employees.
Most taxpayers don't realize how much discretion IRS employees have in applying the law. Revenue officers can approve or deny installment agreements based on their evaluation of your financials. Appeals officers can settle cases based on hazards of litigation. Offer specialists can accept or reject compromise offers based on their calculation of reasonable collection potential. Your attorney knows how to present information that maximizes the chance of favorable exercise of that discretion.
The Tax Law Lawyer Process
Once you hire a tax law lawyer, the process follows predictable steps. Understanding what happens next reduces anxiety.
Initial Case Evaluation
Your attorney reviews all IRS notices, tax returns, and financial documentation. They identify issues, calculate potential liability, and outline resolution options. This evaluation determines strategy.
They'll need several years of tax returns, recent pay stubs, bank statements, asset documentation, and expense records. The more complete your documentation, the faster they can act. Missing information requires reconstruction, which takes time and costs more.
They file Form 2848, Power of Attorney and Declaration of Representative. This authorizes them to represent you before the IRS. Once processed, the IRS deals directly with your attorney. You stop receiving IRS calls and letters.
Negotiation and Resolution
Your tax law lawyer contacts the assigned IRS employee. This might be a revenue officer, appeals officer, or automated collection system employee depending on your case stage. They present your position, submit supporting documentation, and negotiate terms.
Negotiation timelines vary. Simple installment agreements might resolve in weeks. Offers in compromise take months. Tax Court cases can take years. Your attorney manages deadlines and keeps your case moving.
Most cases settle without litigation. The IRS settles about 85% of cases at the administrative level. Tax Court is expensive and time-consuming for both sides. Settlement usually makes sense when there's a reasonable basis for compromise.
Compliance and Follow-Through
After resolution, you must stay compliant. Miss future filing deadlines or payments and the agreement defaults. The IRS can immediately resume collection on the full balance.
Your tax law lawyer often helps you establish systems to maintain compliance. This might include estimated tax payment schedules, quarterly review of withholding, or coordination with your accountant on filing deadlines. Prevention is cheaper than resolution.
Some resolutions require annual financial reviews. Partial payment installment agreements and certain offers in compromise remain contingent on your financial situation. Your attorney helps you prepare these annual submissions.
Questions to Ask Before Hiring
Walk into the consultation with specific questions. The answers tell you whether this attorney can actually help you.
How many cases like mine have you handled? You want specific numbers, not generalizations. If they've handled five offers in compromise, they're learning on your dime. If they've handled five hundred, they know what works.
What's your success rate with this type of case? No attorney wins every case. But they should know their track record. If they can't answer, they're not tracking results.
Who will actually work on my case? Some firms have senior attorneys who sell the case and junior attorneys who work it. Others have experienced attorneys handling everything. Know who you're getting.
What's your fee and what does it include? Get this in writing. Understand what triggers additional fees. Know when you pay and what happens if the case resolves quickly.
What are realistic outcomes for my situation? A good attorney gives you a range of possibilities, not guarantees. They explain best case, worst case, and likely case. They're honest about your chances.
