Resigning as a company director in Australia

A director of an Australian company resigns by giving the company written notice at its registered office (unless the constitution sets a different method). Then they, or the company, must tell ASIC within 28 days. Miss the 28 days and ASIC records the date the notice was lodged, not the date you left. And if you are the only director, your resignation has no legal effect until someone else is appointed.

This guide is written for the departing director. If you are the company and your resident director has resigned, read replacing a resident director instead.

Step 1: Read the constitution and your engagement terms

Section 203A of the Corporations Act is a replaceable rule. It says a director may resign by giving a written notice of resignation to the company at its registered office. A constitution can change that, for example by requiring notice to the chair or allowing email. Also check:

• Your appointment letter or service agreement. Professional and nominee directors usually have a contractual notice period. Ignoring it doesn't stop the resignation taking effect, but it may put you in breach of contract.
• A shareholders' agreement that gives a particular shareholder the right to nominate your seat. They may need to know first.
• Any role tied to the directorship, such as bank signatory, public officer or secretary. Resigning as director doesn't end those roles automatically. Resign from each one separately.

Step 2: Write the resignation letter

Keep it short and unambiguous:

• the company's full name and ACN
• a clear statement that you resign as a director
• the date the resignation takes effect (today, or a future date)
• your signature and the date.

Deliver it to the registered office, keep proof of delivery, and email a copy to the other directors. Don't put your reasons in the letter. If you are leaving because of governance or solvency concerns, record those separately in a letter to the board, keep a copy, and take legal advice.

Step 3: Make sure ASIC is told within 28 days

There are two ways ASIC learns of a resignation.

If you lodge a valid Form 370, the company doesn't also have to lodge its notice (s205B(6)). In practice, don't rely on the company to do it. ASIC's officeholder page confirms you cannot remove yourself through the company officeholder portal, so if relations with the other directors are poor, Form 370 is your safeguard. ASIC's Form 370 page has the current PDF and postal address. Allow for postal time.

Why the 28 days matters so much

Since 18 February 2021, s203AA fixes when a resignation takes effect:

• If ASIC is notified within 28 days of the day you stopped being a director, the resignation takes effect on that day.
• If ASIC is notified later, the resignation takes effect on the day the notice is lodged.

ASIC's announcement of the reforms gives the example of a director who resigned on 1 March but whose resignation wasn't notified until 1 August. ASIC records 1 August. For those five months you remain a director in law, with the duties and exposure that go with it.

The law was aimed at illegal phoenix activity, where directors backdated resignations to escape liability. It now also catches honest directors whose companies simply forgot to lodge.

If the deadline was missed

You or the company can ask for the real date to be fixed:

• within 56 days of the day you stopped being a director, by applying to ASIC on Form 502
• after that, by court application, generally within 12 months, with the order then lodged with ASIC on Form 105 within 2 business days.

ASIC must consider the reasons for the delay, and a court must be satisfied it is just and equitable. Don't count on it. Lodge on time. See ASIC's cessation date guidance.

The last director cannot walk away

Under s203AB, a resignation does not take effect if, at the end of the day it is due to take effect, the company would have no director. The only exception is a resignation taking effect once the company is in winding up. ASIC will reject a Form 370 or Form 484 that would cease the last director without a replacement.

That leaves a sole director with three real options:

1. Find a replacement and have them appointed first, then resign the same day or later.
2. Close the company if it has no future: see closing a company.
3. If the company is insolvent, get insolvency advice about appointing a liquidator or administrator. See insolvent trading and safe harbour.

This is why a professional resident director should never be the only director of a foreign-owned Pty Ltd. If the owners stop responding, a sole resident director is legally stuck in the role. A well-drafted engagement requires the owners to keep at least one other director on the board for exactly this reason.

Resident directors: the s201A angle

If you are the only director who ordinarily lives in Australia, your resignation can take legal effect (there are other directors), but it puts the company in breach of s201A from that day. That is the company's problem to fix, not yours. Still, it is good practice and common in service agreements to:

• give the agreed notice period so the owners can line up a replacement
• tell the board in writing that the company will need a new resident director
• cooperate with the handover (records, portal access, bank mandates).

Exposure doesn't end on the resignation date

Tax

The ATO says a former director can still be personally liable for director penalties relating to:

• company liabilities that fell due before the resignation, and
• liabilities that fell due after it but relate to a period when you were a director. For GST and super guarantee charge, that covers a reporting period that ended before you resigned. For PAYG withholding, it covers a period in which the first withholding event happened before you left.

The ATO's own example: a director resigns on 1 October, the day after the quarter ends. The company lodges its BAS on 28 October showing $20,000 of GST and doesn't pay. The former director gets a $20,000 director penalty. Before resigning, ask for evidence that BAS, PAYG withholding and super are lodged and paid up to date. See director penalty notices.

Duties and insolvency

Your duties attach to decisions made while you held office. Resigning doesn't cure a past breach, and leaving a company you know to be insolvent can attract scrutiny of your conduct beforehand.

Access to records

Under s198F, a former director may inspect the company's books, including financial records, for the purposes of certain legal proceedings, for 7 years after ceasing to be a director. Keep your own copies of board papers and minutes from your time on the board as well.

Resignation checklist

• [ ] Constitution and engagement terms checked for method and notice period
• [ ] Tax, super and solvency position reviewed, with concerns recorded
• [ ] Signed resignation letter delivered to the registered office
• [ ] Separate resignations from secretary, public officer or bank signatory roles

• [ ] ASIC company extract checked to confirm the cessation date
• [ ] Copies of board papers kept

When we hand over to a replacement director, we lodge the resignation once the new director is in place, so the company is never left without a resident director. See how it works.
