What Is the Connecticut Attorney Occupational Tax?

The Connecticut attorney occupational tax is a flat $565 annual charge that most lawyers admitted to the Connecticut Bar must pay by January 15 for the preceding calendar year under Connecticut General Statutes Section 51-81b.¹ The amount does not change with your income or caseload. If you practiced law in Connecticut at any point during the year, you owe it unless you fit one of a handful of specific exemptions: government employment, judicial service, retirement from practice, active military duty of more than six months, or earning less than $1,000 in legal fees.

Who Owes the Tax

If you were admitted to the Connecticut Bar and practiced law in the state during the previous calendar year, the tax applies. Your setting does not matter. Solo practitioners, firm associates, partners, and in-house counsel are all on the same footing, and the $565 is the same for everyone.¹

Attorneys licensed in another state can owe the tax too. The statute reaches anyone admitted pro hac vice by a Connecticut Superior, Appellate, or Supreme Court judge who then practiced law in the state during that year.¹

Attorneys in non-legal jobs sometimes assume they are off the hook. Not always. If you hold an active Connecticut law license and give legal advice or exercise legal judgment in your role, you are likely practicing law for this purpose even if your title says otherwise. A business executive with a J.D. who never does legal work sits in a different place than a “vice president” who reviews contracts and advises on regulatory compliance. The Department of Revenue Services (DRS) looks at what you actually do.

Who’s Exempt

The statute carves out several groups, but the exemptions are not automatic. For most categories you still need to file Form 472, the Attorney Occupational Tax Return, and affirmatively claim the exemption on it.²

Government Attorneys

This is the exemption people get wrong most often. Under subsection (h), no one owes the tax solely because they practiced law as an employee of the state, a political subdivision of the state, or a probate court.¹ Prosecutors, public defenders, and municipal attorneys fall within this exemption when their legal work is entirely through government employment. Take on private clients on the side and the exemption disappears.

Judges

Judges, senior judges, referees, family support magistrates, probate court judges, and federal judges who worked exclusively in a judicial capacity and did not otherwise practice law in Connecticut during the year are exempt.³

Retired or Removed Attorneys

Retired attorneys are exempt, but retirement here is a formal act. You must file written notice of retirement with the clerk of the superior court for the judicial district of Hartford. Simply closing a practice or taking no clients does not count. Attorneys whose names have been removed from the attorney roll kept by that same clerk are also exempt.¹ If you later return to practice, the tax applies again starting in the year you resume.

Minimal Practice and Military Service

Two more exemptions catch narrow situations. Attorneys who do not practice law as an occupation and earn less than $1,000 in legal fees or other legal compensation during the year are exempt. So is any attorney who served on active duty with the U.S. armed forces for more than six months during the tax year.¹

If you paid the tax and later realize you qualified for an exemption, you can file an amended Form 472 to request a refund within three years of the original due date.⁴

How and When to Pay

Form 472 and payment are due by January 15 each year for the preceding calendar year. Connecticut does not mail invoices or reminders, so the deadline is on you. The DRS Taxpayer Service Center (TSC) is the most efficient route and gives immediate confirmation. You file Form 472 whether you owe the full $565 or are claiming an exemption.²

Changing firms or stopping work partway through the year does not reduce the amount. If you practiced at any point during the year, you owe the full $565 unless an exemption applies.

Many firms and corporate employers reimburse the tax. If yours does, the IRS generally treats that reimbursement as taxable compensation that should appear on your W-2.⁵

Penalties for Missing the Deadline

Missing January 15 triggers interest at 1% per month starting January 16, plus a late penalty.¹ On a $565 bill, interest adds up faster than people expect. The DRS can escalate: tax warrants, bank levies, wage garnishments, and in serious cases a tax lien against personal or business assets.

Beyond money, nonpayment can lead to administrative suspension of your Connecticut law license. That is the consequence that blindsides attorneys who treat this as a minor billing matter. A suspension stops you from practicing until the matter is resolved.

The statute does include a safety valve. If the commissioner is satisfied that a failure to file or pay was due to reasonable cause and was not intentional or due to neglect, the DRS can reduce or waive penalties.¹ Do not count on it, but raise it if you have a genuine explanation.

Federal Deductibility

Whether the $565 is deductible on your federal return depends on your status. Self-employed attorneys, including solo practitioners and partners, can deduct it as a business expense on Schedule C, Line 23, which covers licenses and regulatory fees paid to state or local governments.⁶

For W-2 employees, the Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee expenses from 2018 through 2025, so employed attorneys could not deduct the tax at all during those years. That suspension expires at the end of 2025, meaning starting in 2026, employed attorneys who are not reimbursed may again claim the tax as an unreimbursed employee expense on Schedule A, subject to the 2% adjusted gross income floor. Congress could still modify this before it takes effect, so confirm with your tax preparer.

If You Think an Assessment Is Wrong

If you receive an assessment or penalty notice you believe is incorrect, you have 60 days to file a written protest with the DRS Commissioner, setting out your grounds and attaching supporting evidence such as exemption filings or employment records.⁷ If the commissioner rules against you, you have 30 days from that decision to appeal to the Superior Court for the judicial district of New Britain, which requires filing a complaint along with a citation to the commissioner and posting a bond.⁸

A Separate Fee to Know About

The occupational tax is not the only annual obligation. Connecticut attorneys also pay a Client Security Fund Fee administered by the Judicial Branch, not the DRS. It has its own amount, deadline, and payment process, and paying the occupational tax does not satisfy it. Check the Connecticut Judicial Branch website for the current figure and due date so you do not accidentally fall behind on one while handling the other.
