What Is SEC Form TA-1? Transfer Agent Registration Explained

Form TA-1 is the application a company files with the SEC to register as a transfer agent, the entity that keeps the official record of who owns a company's securities. It must be filed and accepted before the applicant can lawfully start performing transfer agent work for any security registered under Section 12 of the Securities Exchange Act of 1934.

What a transfer agent does, and why it registers

A transfer agent maintains the record of registered shareholders for an issuer, processes the transfer of shares between owners, pays dividends and interest, and handles related tasks like replacing lost certificates and mailing proxy materials. Because it sits between public companies and their shareholders, Congress added transfer agent registration and oversight to the Securities Exchange Act of 1934 through Section 17A, after settlement problems in the registered-securities system in the late 1960s and early 1970s.

Section 17A makes it unlawful for an entity to perform a transfer agent function for a security registered under Section 12 without first registering with the appropriate regulatory agency. For most transfer agents, that agency is the SEC. A transfer agent that is itself a bank registers instead with its own banking regulator (the Office of the Comptroller of the Currency, the Federal Reserve Board or the FDIC, depending on the bank's charter), using the same uniform form.

What Form TA-1 asks for

Form TA-1 collects the information the relevant regulator needs to decide whether to accept the registration and to keep a current picture of who operates in the transfer agent business:

An applicant that outsources every transfer agent function to a service company (a firm that performs the mechanics of transfer agent work for others) only has to complete a short part of the form plus the signature section. An applicant that keeps some functions in house fills in the whole form and reports zero for whatever it has outsourced.

How registration actually proceeds

Filing Form TA-1 does not register the applicant immediately. Under the rule, registration becomes effective 30 days after the regulator receives an acceptable Form TA-1, unless the regulator takes action sooner to accelerate the effective date, or acts to postpone or deny the registration. In practice, an applicant should treat the 30-day window as the earliest it can lawfully begin transfer agent work, not a guarantee that it will be able to.

Once registered, a transfer agent has to keep the form accurate. Amendments are due within 60 days of any change to the information reported on the original Form TA-1 or a later amendment, filed as a Form TA-1/A.

TA-2 and TA-W: the rest of a transfer agent's EDGAR paperwork

Form TA-1 is only the entry point. Two related forms cover the rest of a registered transfer agent's life cycle:

• Form TA-2 is the transfer agent's annual report, required under SEC Rule 17Ac2-2, covering the prior year's activity (volume of items processed, turnaround performance and similar operational figures). It is due by March 31 following the year it reports on, and since 2007 every registered transfer agent has had to file it electronically through EDGAR, including transfer agents whose primary regulator is a bank regulator rather than the SEC.
• Form TA-W withdraws a transfer agent's registration when it stops acting as one. You can read more about Form TA-2's annual reporting detail and Form TA-W withdrawals on the transfer agent dataset page.

Together, TA-1, TA-1/A, TA-2 and TA-W give a full public record of who is registered to act as a transfer agent, when they registered, what changed, and when they left the business, the same way EDGAR tracks registration and deregistration events for other market participants.

Finding transfer agent filings instead of reading them one at a time

EDGAR's company search works filer by filer: look up one transfer agent's CIK, then browse its filings. That is fine for checking a single company, but it does not let you watch new registrations or withdrawals across the whole transfer agent population as they happen.

SecFeed indexes every EDGAR filing by form type, so you can pull current TA-1, TA-1/A or TA-W filings in one query instead:

curl -G "https://secfeedapi.com/v1/filings" \
  --data-urlencode 'query=formType:"TA-1" OR formType:"TA-1/A" OR formType:"TA-W"' \
  --data-urlencode "sort=desc" \
  --data-urlencode "size=20" \
  -H "Authorization: Bearer YOUR_API_KEY"

Each row comes back with the filer's CIK, name, form type and filing date, the same shape as any other filing search result:

{
  "accessionNo": "0001234567-26-000041",
  "cik": "1987654",
  "ticker": null,
  "companyName": "EXAMPLE TRANSFER SERVICES LLC",
  "formType": "TA-1/A",
  "filedAt": "2026-10-14",
  "linkToFilingDetails": "https://www.sec.gov/Archives/edgar/data/1987654/000123456726000041/0001234567-26-000041-index.htm"
}

Filtering that result set to formType:"TA-1" alone gives new registrations, "TA-1/A" gives amendments to watch for ownership or control changes, and "TA-W" gives withdrawals, which is the closest public signal to a transfer agent exiting the business. In Python, the same search reads as:

from secfeed import Client

sf = Client("YOUR_API_KEY")
withdrawals = sf.filings(query='formType:"TA-W"', sort="desc", size=20)
for f in withdrawals["filings"]:
    print(f["filedAt"], f["companyName"], f["accessionNo"])

Because every result carries an accessionNo, you can follow up with the full filing index for any other form the same filer has submitted, which is useful if a transfer agent's withdrawal coincides with other corporate changes at the companies it served.

Frequently asked questions

Who has to file Form TA-1?

Any entity that performs a transfer agent function for a security registered under Section 12 of the Securities Exchange Act of 1934 must register before doing so. Most file with the SEC; transfer agents that are banks file with their own banking regulator instead.

How long does Form TA-1 registration take?

Registration becomes effective 30 days after the regulator receives an acceptable Form TA-1, unless the regulator accelerates, postpones or denies it before then.

What is the difference between Form TA-1 and Form TA-2?

Form TA-1 is the initial registration (and its amendments, filed as TA-1/A). Form TA-2 is the annual report a registered transfer agent files afterward, due by March 31 each year, covering the prior year's activity.

How does a transfer agent deregister?

By filing Form TA-W, the notice of withdrawal from registration. It is the form that removes a transfer agent from the registered population on EDGAR.

Is Form TA-1 the same everywhere a transfer agent operates?

The form itself is uniform across regulators, but which regulator receives it depends on the applicant: the SEC for most transfer agents, or the applicant's banking regulator if it is a bank.
