What is a government letter?
A government letter is official correspondence from a department or agency — tax, social security, immigration, local council, or a regulator — that usually falls into one of a few categories: a request for information, a decision or assessment, a notice of an obligation, or a penalty or infringement. Working out which one you've received is usually the first step to understanding what to do next.
Unlike most consumer correspondence, government letters often carry legally binding deadlines. Missing a response window can close off your right to object or appeal, even if the underlying decision was wrong — which is why identifying the deadline is usually more urgent than fully understanding every clause.
When you'll come across one
You'll receive one after lodging a tax return or benefit application, when a government database identifies a change in your circumstances, following an infringement or compliance check, or as a routine notice such as a rates or renewal reminder. Some are purely informational; others require action within a set number of days.
It's worth reading the entire letter once for context before acting on the first instruction you see — many government letters bury the actual required action, and the review or objection rights that apply to it, several paragraphs in.
Key terms to know
- Notice of assessment/decision
- The formal record of a decision that's been made about your situation (tax owed, benefit eligibility, a penalty). It usually starts a countdown for any right you have to request a review.
- Objection/review period
- A defined window, often 28 to 60 days depending on the agency, during which you can formally dispute a decision. Once it lapses, you may need to apply for an extension or lose the right altogether.
- Infringement notice
- A formal notice alleging a specific breach and setting a penalty, distinct from a criminal charge. Most allow you to pay, dispute, or in some cases request the matter go to a tribunal or court instead.
- Internal review
- A reconsideration of a decision carried out by the same agency, usually the first and fastest step before an external appeal body.
- External appeal/tribunal
- An independent body that can review a government decision after internal review is exhausted (or sometimes instead of it), separate from the original decision-maker.
- Compliance/verification check
- A request for supporting documents or evidence to confirm information you've already provided, not necessarily an accusation of wrongdoing.
- Debt/overpayment notice
- A notice that money paid to you (a benefit, a rebate) is now being reclaimed, often because of a data-matching discrepancy. These can usually be disputed or arranged into a payment plan.
- Service of notice
- The legal rule about when a letter is considered "received" for deadline purposes — often a fixed number of days after the date on the letter, regardless of when you actually opened it.
What to check before you agree to anything
The actual deadline, not just the letter date
Look for a specific response-by date, and separately check the assumed "service" date the agency uses to start counting — it may not be the day you opened the letter.
Which category of letter this is
A request for information usually just needs a response; a notice of a decision usually starts an objection clock. Treating one as the other can waste your window to formally dispute something.
Whether a review or appeal right is mentioned at all
Not every letter states its review rights clearly. If the letter doesn't mention one, it's still worth asking the agency directly whether a review process exists.
Any amount claimed or owed, and how it was calculated
Debt and overpayment notices in particular are often based on data-matching that can be wrong; ask for a full calculation before assuming the figure is correct.
Whether responding now waives your right to dispute later
Some infringement notices treat payment as an admission. If you intend to dispute something, check whether paying first forecloses that option.
Contact details for the actual case officer or reference number
Generic hotlines are often less useful than a direct reference number to quote, which the letter usually includes near the top.
Questions worth asking first
- What exactly do I need to do, and by what specific date?
- What happens if I miss this deadline — is there any way to request an extension?
- Do I have a right to a review or appeal of this decision, and how do I start that process?
- How was this amount or decision calculated, and can I see the basis for it?
- Will responding or paying now affect my ability to dispute this later?
Frequently asked questions
What should I do first when I receive a government letter I don't understand?
Identify which category it falls into — a request for information, a decision, or a penalty — and find the specific deadline. That determines how urgently you need to act and what your options are.
Can I still dispute a decision after the review period has passed?
Sometimes, through an extension request or an external appeal body, but it's harder and not guaranteed. Acting within the stated window is always the safer path.
Is it true that ignoring a government letter makes the problem go away?
No — most agencies proceed with the stated decision, debt recovery or penalty by default if you don't respond, and missing a deadline can close off rights you'd otherwise have had.
What's the difference between an internal review and an external appeal?
An internal review is handled by the same agency that made the decision, and is usually faster and simpler. An external appeal goes to an independent tribunal or body and is typically used after internal review, or when you disagree with its outcome.
Should I pay an infringement notice if I think it's wrong?
Not necessarily — check whether the notice allows you to dispute it instead of paying, and whether paying is treated as accepting the penalty, before deciding how to respond.
