The envelope comes from the IRS. It sits on the kitchen table for three days before anyone opens it. Inside is a number that looks like a typo, plus a deadline that is closer than it should be. Thousands of Atlanta households and small businesses face that moment every year. Some owe back taxes. Some got audited. Some are dealing with a Georgia Department of Revenue bill on top of a federal one.
A good tax lawyer changes how that story ends. Here are six Atlanta firms with real depth in IRS and state tax problems, laid out so you can compare them fast.

How This List Came Together
Every firm here works on tax problems as a core practice, not a side line. We looked at who leads each firm, what they did before, public recognition, and the kinds of cases they take. A firm that fits a Fortune 500 audit may not fit a family with $30,000 in back taxes, so each entry names who it serves best.
1. Wiggam Law
Jason Wiggam built this firm on one idea: people with tax problems deserve lawyers who do nothing but tax. He earned his law degree magna cum laude from Georgia State and later his tax LL.M. from NYU. In law school, he spent a year and a half at Georgia State’s low-income taxpayer clinic, helping people who could not pay for a lawyer. He still sits on that clinic’s advisory board.
Today the firm has a deep bench of attorneys and enrolled agents. They handle IRS collections, offers in compromise, audits, unfiled returns, payroll tax, innocent spouse relief, and conservation easement disputes. One client with an innocent spouse denial saw the IRS reverse course on appeal, dropping a bill of over $1 million to $200,000. Free case reviews start the process.
Best for: anyone facing IRS or Georgia tax debt who wants a full team focused only on tax.

Before You Hire Anyone
Bring every IRS letter you have to the first meeting. Ask who will do the actual work on your file. Ask whether the fee is flat or hourly, and what it covers. And do not call the IRS yourself before you talk to a lawyer.
FAQ
How much does a tax lawyer cost in Atlanta? Many charge between $200 and $600 an hour. Some offer flat fees for set tasks, like an offer in compromise. Ask for the fee in writing.
Can I go to jail for owing the IRS? Owing taxes is not a crime. Jail is for rare cases of willful fraud or evasion. A lawyer can help you fix the debt long before that is a risk.
Should I hire a tax lawyer or a CPA? A CPA is great for filing returns. A tax lawyer can take your case to Tax Court, and your talks with them are protected by attorney-client privilege. That matters most if a case could turn criminal.
How long do I have to respond to an IRS notice of deficiency? You usually have 90 days to file a petition in Tax Court. Miss it and you lose that option, so act fast.
Can the IRS settle for less than I owe? Yes. An offer in compromise lets some people settle for less than the full balance. The IRS looks at your income, expenses, and assets to decide.
Parting Word
That IRS envelope does not get smaller while it sits unopened on the table. Pick a firm from this list, make the call this week, and let someone who does this every day carry the weight with you.
