Key points

The Job Accommodation Network states that there is generally no obligation to disclose disability-related information until an accommodation is needed.
The EEOC says an employer that learns of a mental health condition must keep the information confidential, even from co-workers.
Disclosing after a poor review or discipline does not erase what has already happened, which is why JAN advises asking before job performance suffers.
A New York City employer with four or more persons must engage in a cooperative dialogue and issue a written final determination once you request an accommodation.
HIPAA limits what your clinician may release to an employer without your authorization; it does not govern what the employer does with information you hand over yourself.

Whether to tell an employer about ADHD is a personal decision with legal consequences in both directions. Staying quiet keeps the diagnosis private. It also means the employer has no known disability to accommodate. The rules below are current as of October 2026 and are general information, not legal advice. An employment attorney or the Job Accommodation Network can talk through an individual situation.

Are you ever required to disclose?

In most jobs, no. The Job Accommodation Network (JAN) puts it this way: "Generally there is no obligation to disclose disability-related information" until an accommodation is needed. Before a job offer, an employer usually cannot require disclosure.

The EEOC's guidance on mental health conditions says you can usually keep a condition private. Under the ADA an employer may ask medical questions in four situations:

when you request a reasonable accommodation;
after a job offer but before work starts, if everyone entering the same job category is asked;
for affirmative action purposes, where answering is voluntary;
on the job, when there is objective evidence that you may be unable to do the job or may pose a safety risk.

Some regulated jobs have their own medical rules, which are covered separately in ADHD rules for pilots, commercial drivers and military service.

What you gain and what you risk

	Disclosing	Not disclosing
Accommodations	Starts the employer's duty to consider reasonable accommodation	No formal accommodation; you rely on your own strategies and informal flexibility
Legal protection	Creates a record that the employer knew of the condition and the request; retaliation for requesting an accommodation is unlawful under New York Executive Law 296(7)	Harder to show later that a decision was connected to a disability the employer did not know about
Privacy	The employer must keep the information confidential, but a supervisor or HR will know	The diagnosis stays between you and your clinician
Timing risk	Early disclosure can come before problems appear on the record	If performance slips first, disclosure does not undo discipline already issued
Perception	Reactions vary by workplace and manager, and the law cannot fully control them	No change in how colleagues see you

JAN's advice on timing is that it is "better to disclose a disability and request accommodation before job performance suffers." Disclosure does not automatically cancel a poor review or a warning that has already been given.

There is a middle route. Many useful changes (written follow-ups after meetings, a quieter desk, calendar reminders) can be requested as ordinary work preferences without naming a medical condition. That keeps your privacy but gives you no legal claim if the answer is no.

Who has to keep it confidential

Once an employer has medical information, several rules apply:

Under the ADA, employers must keep medical records and information confidential and in separate medical files.
EEOC guidance allows sharing only in limited circumstances with supervisors, managers, first aid and safety personnel, and government officials investigating compliance with the ADA.
The EEOC's mental health guidance says the employer "must keep the information confidential, even from co-workers."
The state regulation says: "The employer must maintain the confidentiality of individuals' medical information" (9 NYCRR 466.11(j)(5)).

JAN adds that there is no requirement to inform coworkers about a disability or a need for accommodation. A colleague who asks why you have a different schedule is not entitled to a medical answer.

HIPAA plays a smaller part than most people expect. The federal Department of Health and Human Services explains that the Privacy Rule generally does not apply to the actions of an employer. It does stop your clinician from giving information to your employer without your authorization. The full picture is in who can see your ADHD diagnosis and prescriptions in New York.

How to make the request

EEOC guidance says a request can be in plain English and does not need the phrase "reasonable accommodation." It does need to connect the change to a medical condition. JAN recommends telling someone who can act on it, such as a manager, supervisor or HR, and notes that a written request helps if there is later a dispute about when you asked.

Pick the recipient. HR is often the better first stop if you would prefer that your direct manager know only the accommodation and not the reason.
Decide how much to say. The EEOC notes that if you do not want the exact diagnosis shared, a more general description from your provider may be enough.
Name the work problem and the change. Be specific about the task and the fix.
Offer documentation. An employer may ask for a letter from your clinician. It generally cannot demand your complete medical records.
Keep a copy with the date sent.

A short written request might read: "I have a medical condition that affects my concentration in open-plan settings. I am requesting two changes as a reasonable accommodation: a desk away from the main walkway, and written confirmation of assignments given verbally. I can provide a letter from my doctor. Could a time be set this week to discuss?"

The laws behind the request, and a list of accommodations commonly used for ADHD, are in ADHD workplace accommodations in New York.

The New York City cooperative dialogue

If your employer has four or more persons and is covered by the New York City Human Rights Law, an extra procedure applies. Since October 15, 2018 (Local Law 59 of 2018), it is an unlawful discriminatory practice to refuse or fail to engage in a cooperative dialogue within a reasonable time with a person who has requested an accommodation or who the employer has notice may require one.

The city code defines the dialogue as engaging in good faith, in writing or orally, about your accommodation needs, potential accommodations including alternatives to the one requested, and the difficulties they may pose for the employer. Three points are worth knowing:

At the end, the employer must give you a written final determination identifying any accommodation granted or denied (NYC Admin. Code 8-107(28)(d)).
An employer can conclude that no reasonable accommodation exists only after the dialogue has happened or been attempted.
Holding the dialogue is not, by itself, a defense to a claim that a reasonable accommodation was not provided.

Outside New York City this procedure does not apply. The state regulation still says the employer "has a duty to move forward to consider accommodation once the need for accommodation is known or requested."

If disclosure goes badly

Write down what was said, by whom and when, and keep copies of emails outside your work account where your employer's policies allow it. Retaliation for asserting disability rights is unlawful under the ADA and state law. Agencies and deadlines are set out in how to file a disability discrimination complaint in New York. For the clinical side, including treatment that may reduce how much accommodation you need, see the ADHD at work resources.

Questions

Can an interviewer ask whether I have ADHD?

Before a job offer an employer usually cannot require you to disclose a disability. After an offer, medical questions are allowed only if everyone entering the same job category is asked.

Will my coworkers be told?

They should not be. The EEOC says an employer must keep information about a mental health condition confidential, even from co-workers, and there is no requirement that you tell colleagues yourself.

Do I have to give my employer the exact diagnosis?

Not always. EEOC guidance says that if you do not want the exact diagnosis shared, a more general description from your provider may be enough. The letter still has to show that a medical condition creates the need for the change.

Can I disclose after I have already received a warning?

Yes, you can ask for an accommodation at any time. The Job Accommodation Network cautions that disclosure does not automatically erase discipline or a poor review that came first, so earlier is generally safer.

Does HIPAA stop my employer from asking for a doctor's note?

No. HIPAA restricts what your health care provider can release without your authorization. It does not restrict the employer's question, and an employer may ask for reasonable documentation when you request an accommodation.
