What we do

Which of these sounds like you?

Most people who call us are dealing with one of six situations. Pick the one that fits and you will land on the page that explains what happens next, what it costs to wait, and how we handle it.

Crypto tax

You trade, stake, or hold crypto and the IRS is involved, or you are worried it will be

An IRS letter about crypto, a 1099-DA that does not match your records, years you never reported, or crypto lost to a scam. We have focused on this since 2014.

See how we help
Tax controversy

You are facing a tax dispute or investigation involving the IRS or the State of Illinois

A balance you cannot pay, an audit notice, a levy or lien, a sales tax audit, or a case that may become criminal. We take over the communication and the strategy.

See how we help
International tax

You have foreign accounts or income and are not sure you reported them

A bank account abroad, an inheritance from overseas, years living outside the U.S. without filing, or a form you just learned exists. Get compliant before the IRS asks.

See how we help
Opinion letters

You need a signed legal opinion someone else will rely on

A tax position your preparer will not sign without support, or a crypto theft loss you plan to deduct. A written opinion documents the analysis before you file.

See how we help
Business law

You want to protect what you own, or you are buying or selling a business

Asset protection for anyone with something to lose, business owner or not: structuring so creditors cannot easily reach what you own, done before the problem exists. And for owners, buying or selling a company with the tax consequences handled by the same team.

You want your returns done right by people who also defend them

Federal tax matters do not need a local attorney

Reviews are the opinions of individual clients and do not predict the outcome of any matter.

Why Gordon Law

How we are different

Since 2012

Fourteen years across the table from the IRS

Andrew Gordon opened the firm in 2012 after clerking at the IRS Office of Chief Counsel. Since then our attorneys have handled audits, collections, appeals, and Tax Court cases through every enforcement cycle, and we have added a former IRS attorney and a former prosecutor to the bench along the way.

Crypto tax and law

Focused on crypto since 2014, and still the core of the practice

Our first crypto matter came from an Ethereum developer in 2014, before most preparers had heard the word. Crypto tax and digital asset law are now the majority of what we do: audits, IRS letters, unreported years, theft loss opinions, and the policy work in Washington that shapes the rules.

Thousands of clients

We have helped thousands of clients, and the reviews are theirs

Individuals, investors, founders, and businesses in all 50 states, with 222 five-star reviews on Google to show for it. Every client works with an attorney, hears from us at least every 30 days, and knows that what they tell us is privileged.

The attorneys

Who you will actually work with

Every matter is staffed with the attorney whose background fits it. These are the people who sign the letters, sit in the audits, and stand up in Tax Court.

Results depend on the facts of each matter and are not a prediction of the outcome in your case.

Crypto exchanges now report to the IRS. Here is what that means for you.

Exchanges, brokers, and crypto payment platforms report your sales and trades to the IRS on Form 1099-DA, and the IRS matches those forms against your return. In the first years the forms often show proceeds with no cost basis, which can overstate your gain. If your records and the broker’s do not line up, the mismatch, not the trade, is what triggers the letter. Our attorneys and accountants reconcile the forms, fix prior years, and respond if the IRS has already written.
