Quick answer
The ATO says the 21 days on a director penalty notice start on the day it posts the notice or leaves it at the address registered with ASIC. If that address is out of date, or mail sits unopened at an accountant's office, days disappear before you know. Check your company and director addresses on the ASIC register, update changes within 28 days, and set up a weekly mail and inbox routine.
Key points
- A DPN's 21 days run from posting, not from when you open it.
- DPNs are generally sent to the director's address on the ASIC register.
- Companies must tell ASIC about address changes within 28 days.
- A weekly routine for post, myGov and ATO online services protects every deadline.
Here’s a scenario we hear more often than you’d think. A director moves house. The company’s registered office is still the old accountant’s address from five years ago. A director penalty notice is posted, sits in a tray for a week, gets forwarded to the wrong place, and finally lands on the director’s kitchen table with a handful of days left out of 21.
Nothing about the debt changed. What changed was the time available to deal with it. This guide is about making sure that never happens to you.
Why does the address matter so much?
Because several of the most serious letters start their clocks when they’re sent or left, not when they’re read.
The ATO’s own wording on director penalty notices is clear: the 21 days start on the day it posts the DPN or leaves it at the address registered with ASIC. For current directors, it will generally send the DPN to the address registered with ASIC.
Statutory demands are served on the company, commonly at its registered office. The company’s 21 days run from service. If the registered office is an address nobody checks, the company’s time is quietly ticking away.
| Letter | Where it’s typically sent | When the clock starts |
|---|---|---|
| Director penalty notice | Director’s address on the ASIC register | The day it’s posted or left there |
| Statutory demand | Company’s registered office | Service on the company |
| ATO reminders and warnings | Your nominated addresses, myGov inbox, SMS | When sent — act promptly |
| Notice of intent to disclose | ATO records | 28 days from receiving it |
Our debt letter triage tool counts these clocks for you, but it can only count from the date you enter. If you find a letter late, use the date printed on it.
What should I check on the ASIC register?
Set aside ten minutes to look up your company on the ASIC register and check:
- Registered office address. Is it an address where mail is opened promptly?
- Principal place of business. Is it current?
- Each director’s residential address. Is yours up to date? This is where a DPN will generally go.
- Officeholders. Are former directors removed and current ones listed correctly?
ASIC says companies must notify it within 28 days when the registered office or principal place of business changes, or a late fee applies. Changes lodged through the officeholder portal take effect seven days after submission. Put a reminder in your calendar to recheck the register whenever you move.
What if my accountant is the registered office?
That’s common and perfectly sensible — as long as there’s a clear arrangement. Agree in writing:
- Turnaround time. Mail opened and scanned to you within one business day.
- Priority flags. Anything from the ATO, ASIC, a court, a lawyer or a lender gets a phone call, not just an email.
- Holiday cover. Who checks the mail when the office closes over Christmas or Easter?
- Change of accountant. If you move firms, update the registered office before the relationship ends.
How do I stop digital notices slipping through?
Physical mail is only half of it. The ATO says it may contact you by SMS, phone, myGov inbox or letter about overdue lodgements. Build a weekly routine:
- Monday: open all physical mail, including anything forwarded from the registered office.
- Monday: check your myGov inbox and ATO online services for business.
- Monday: scan your email for anything from the ATO, ASIC, courts or lawyers (and check your spam folder).
- Monthly: confirm the ATO balance by tax type, as part of the monthly check.
It sounds dull. It’s also one of the highest-value habits a director can have.
What if a letter has already arrived late?
Don’t waste time on how it happened. Work out how many days are genuinely left:
- Find the date on the letter and enter it in the triage tool.
- Read what the letter requires and the consequences if the date passes.
- Start on the solution immediately. For a DPN, that’s usually payment — see the director penalty notice page. For a statutory demand, it’s paying, settling or applying to set aside — see the statutory demand page.
- Get advice on your specific position, especially if you believe the letter wasn’t validly given.
If the fix involves funding and the deadline is close, contact a lender straight away rather than after you’ve gathered every document. You can start an enquiry in about a minute, with no credit check involved.
An illustrative example
Illustrative only. A Newcastle electrical contracting company uses its former accountant’s office as its registered office. One director moved house two years ago and never updated ASIC. When the company falls behind on PAYG withholding, the ATO posts a DPN to the director’s old address. The new owners of the house drop it back in the mail, and it reaches the director eight days after the posting date.
The director uses the remaining time well: she confirms the ATO balance, arranges a second mortgage over an investment property, and pays the ATO before the deadline. Then she updates both the registered office and her residential address with ASIC, and sets up a Monday mail routine. The next letter from the ATO — a routine reminder months later — is dealt with the day it arrives.
What else belongs in a “never miss a deadline” setup?
- A shared deadlines calendar with your bookkeeper or accountant: BAS dates (21st of the month for monthly lodgers; 28 October, 28 February, 28 April and 28 July for quarterly), payday super deadlines, lease reviews and loan expiries.
- Mail redirection whenever you move, for at least 12 months.
- An up-to-date contact list of who to call when a serious letter lands: accountant, lawyer, and a funder.
- A document folder you can send quickly — see the debt rescue document pack.
How do I know a letter or message is genuine?
Scammers imitate the ATO and ASIC, especially around tax time. If a letter, email or text asks for urgent payment, be careful:
- Check the debt in ATO online services or with your tax agent rather than using a link or number in the message.
- Call the ATO on its published number, 13 11 42, if you’re unsure.
- Be wary of unusual payment methods — gift cards, cryptocurrency, or bank details that don’t match the ATO’s official payment options.
- Look for real details. Genuine ATO correspondence about a debt should match what you see in online services.
The goal is balance: act fast on genuine notices, but verify before you pay anything unexpected.
Who should own the mail routine in a small company?
Write it down, even if it’s one line each:
| Task | Owner | Backup |
|---|---|---|
| Open physical and forwarded mail | Director or office manager | Second director |
| Check myGov inbox and ATO online services | Director | Bookkeeper or tax agent |
| Update ASIC details after any move | Company secretary or director | Accountant |
| Log deadlines in the shared calendar | Whoever opens the letter | Bookkeeper |
When it’s everyone’s job, it’s nobody’s job — and deadlines slip through exactly that gap.
Want a plan in place before the next letter?
The best time to know your funding options is before a deadline starts ticking. A short conversation now means that, if a DPN or demand ever does arrive, you’ll spend the 21 days acting instead of researching.
It takes about a minute to enquire, with no credit check when you do. We don’t pass your details around a pack of lenders — a real person looks at your situation and calls you. Please be accurate about what the business owes, any letters received and the property you own, so we can give you a clear picture of what’s possible.
Frequently asked questions
Where does the ATO send a director penalty notice?
For a current director, the ATO says it will generally send the DPN to the address registered with ASIC. The 21 days start on the day it posts the notice or leaves it at that address.
What if I never received the DPN because my address was out of date?
The clock generally still runs from the date the notice was posted or left at the registered address. That's why keeping your ASIC details current matters so much. If you find a DPN late, act immediately and get advice.
How long do I have to update my company address with ASIC?
ASIC says companies must notify it within 28 days of a change to the registered office or principal place of business, or a late fee applies. Changes lodged through the officeholder portal take effect seven days after submission.
Can my accountant's office be the registered office?
Yes, many companies use their accountant's address. If you do, agree how quickly mail will be scanned and sent to you, because deadlines can start when a letter arrives there.
Does the ATO send letters by email or myGov?
The ATO says it may contact you by SMS, phone, myGov inbox or letter about lodgements. Check your myGov inbox and ATO online services regularly alongside physical mail.
