Guide scope

This guide is a practical starting point for Australian landlords. Tenancy rules, authority processes and forms can change by state or territory, so use it to understand the workflow, then check the current authority process before issuing formal notices, lodging tribunal applications or making legal or financial decisions. Landlord Wise can help you organise records and ask Wise AI state-specific questions.

If you’re a self-managing landlord in Tasmania, increasing the rent is one of the few actions you take during a tenancy that is governed by its own dedicated set of rules in the Residential Tenancy Act 1997 (Tas). The Act does not cap the amount you can charge — Tasmania has no rent cap and no index-linked limit — but it does strictly control when you can increase the rent, how you must notify the tenant, and how long the tenant has to challenge the increase if they believe it is unreasonable.

Get any of these three things wrong and the increase is either invalid, challengeable, or both. A rent increase notice that fails to meet the Section 20 requirements simply does not take effect — the tenant continues to be liable only for the previous rent amount, and you cannot enforce the higher figure.

This guide covers every part of the rent increase process for landlords in Tasmania: the minimum notice period, the 12-month interval rule, what the notice must contain, the tenant’s right to apply to the Residential Tenancy Commissioner for an unreasonable rent increase determination, and what happens if either party takes the matter to the Magistrates Court.

If you’re changing rent during an existing tenancy, it helps to review the Tasmania lease agreement guide and the broader Tasmania residential tenancy act guide first. If money is later disputed at the end of the tenancy, our Tasmania rental bond guide guide is the other page you’ll most often need.

When You Can Increase the Rent

In Tasmania, your ability to increase the rent is governed by Section 20 of the Residential Tenancy Act 1997. This section sets out two preconditions that must both be satisfied before a rent increase can take effect.

Precondition 1: The Lease Must Allow It (Or There Must Be No Written Lease)

Under Section 20(1), an owner may increase the rent by written notice to the tenant only if the written residential tenancy agreement allows for an increase, or if there is no written residential tenancy agreement for the premises.

In practice, nearly every written lease in Tasmania contains a clause permitting rent increases in accordance with the Act — but if your lease is silent on the point, or contains a clause that prohibits increases during the term, you cannot increase the rent. If you are operating without a written lease (which is legally permissible but significantly disadvantageous to you as the owner), Section 20(1)(b) expressly permits rent increases.

If your lease does not allow for an increase, the only way to lawfully raise the rent is to wait for the fixed term to expire and enter into a new agreement with updated rent — and even then, the 12-month interval rule still applies.

Precondition 2: The 12-Month Interval Rule

This is the rule that catches the largest number of self-managing landlords. Under Section 20(3), an increase in rent may only take effect from a day that is more than 60 days after the day on which the notice is given AND is a day that is:

  • not less than 12 months after the residential tenancy agreement commenced or was extended or renewed; or
  • if rent has been previously increased, more than 12 months after the last increase; or
  • if the Commissioner has made an order under Section 23(3) reducing an increase, more than 12 months after the date of that order.

The 12-month clock is tied to the rent itself, not to the agreement. If the tenant has been in the property for three years and you last increased the rent 8 months ago, you cannot increase it again for another 4 months — even if the fixed term has just been renewed. Renewing the lease does not reset the 12-month clock if there was a prior increase within the last 12 months.

The interval applies to the effective date of the new rent, not the date you send the notice. You can send the notice earlier than 12 months out, provided the effective date on the notice satisfies both statutory thresholds — not less than 12 months after the tenancy commenced, was extended or renewed, and more than 12 months after the last increase — and is more than 60 days from the day the notice is given.

Social Housing Exception

Section 20(3A) creates a limited exception for residential tenancy agreements that relate to social housing. For social housing tenancies, the 12-month interval rule does not apply — but the 60-day minimum notice period still does. This exception has no application to a typical private landlord; it is specific to social housing providers under the Homes Tasmania Act 2022 and equivalent arrangements.

How to Give a Valid Rent Increase Notice

Unlike some other states, Tasmania does not prescribe a specific Government-issued form for rent increase notices. Section 20(1) simply requires “written notice to the tenant.” However, the content requirements in Section 20(2) are mandatory: the notice must specify both the amount of the rent as increased and the day from which the increase takes effect.

What the Notice Must Contain

Section 20(2) requires your written notice to specify:

  • the amount of the rent as increased — the new weekly, fortnightly, or monthly rent figure (not the dollar increase, but the new total)
  • the day from which the increase in the rent takes effect — a specific calendar date

A notice that fails to specify either of these elements does not comply with Section 20 and will not lawfully increase the rent. The tenant remains liable only for the previous rent amount.

How to Deliver the Notice

“Written notice” in Tasmania is a broad term. Email is generally accepted as written notice, provided you can prove the tenant received it. Post (with evidence of posting and allowing for postage delivery time) and hand delivery are also valid. Whichever method you use, keep a dated copy of the notice and evidence of when and how it was sent — if the tenant later challenges the increase or the notice period, you need to be able to prove what you sent and when.

A practical rule: allow additional days beyond the 60-day minimum if you are sending by post. The 60-day clock runs from the day the notice is given to the tenant, which is the day they receive it — not the day you posted it.

A Sample Notice Structure

A compliant rent increase notice typically contains:

  • the property address
  • the tenant’s full name
  • your name and contact details (or your agent’s)
  • the current rent amount and payment frequency
  • the new rent amount and payment frequency
  • the specific date from which the new rent takes effect (being a date more than 60 days after the notice is given, not less than 12 months after the tenancy commenced or was last extended or renewed, and more than 12 months after any previous rent increase)
  • a reference to Section 20 of the Residential Tenancy Act 1997 as the statutory authority for the notice
  • the date the notice is given and your signature

The Act does not require the reference to Section 20 or a signature block to be included, but both strengthen the notice’s evidentiary value if the tenant later challenges it.

Counting the 60 Days

Section 20(3) requires the effective date to be more than 60 days after the day the notice is given — not 60 days, not “at least 60 days,” but more than 60 days. The conservative approach is to count 61 days or more from the day the tenant receives the notice. A notice sent today with an effective date exactly 60 days from now does not satisfy Section 20.

When working backwards from a desired effective date, allow at least 63–65 days to account for delivery time, the strict “more than 60 days” requirement, and any risk that the tenant disputes when the notice was received.

The Tenant’s Right to Challenge an Unreasonable Increase

Section 23 of the Residential Tenancy Act 1997 gives the tenant the right to apply to the Residential Tenancy Commissioner for an order declaring that a rent increase is unreasonable. This is the primary mechanism through which rent increases are contested in Tasmania, and every landlord increasing the rent should understand how it works.

Who Can Apply and When

Under Section 23(1), only the tenant can apply to the Commissioner for an unreasonable rent increase order. The owner has no equivalent right to seek confirmation that an increase is reasonable before imposing it.

Section 23(1B) sets a strict 60-day limitation period: the tenant must make the application within 60 days after being notified of the increase under Section 20. If the tenant does not apply within this window, they lose the right to challenge the increase through the Commissioner — although they retain the right to simply give notice and leave if the new rent is unaffordable.

The application must be made on the Residential Tenancy Commissioner’s prescribed form (titled “Application for unreasonable rent increase”), must be accompanied by the prescribed fee under Section 23(1A), and must be supported by evidence. The Commissioner publishes the application form on the MyBond website.

What Evidence the Tenant Must Provide

The Commissioner’s application form requires the tenant to submit the lease agreement and the notice of rent increase as mandatory documents. The tenant is also asked to provide information about why they believe the increase is unreasonable, which typically includes:

  • examples of rental prices for similar properties in a comparable area
  • background information about the tenancy
  • details of any other rent increases during the tenancy
  • outstanding maintenance issues at the property
  • improvements made to the property (or the absence of any)

Tenants who engage with the Residential Tenancy Commissioner tend to present a structured case comparing your rent to local market evidence and raising any maintenance or condition issues. A landlord who has been diligent about repairs, condition reports, and rent-comparison research before serving the increase is in a much stronger position when this evidence is tested.

How the Commissioner Decides

Section 23(2) sets out the test the Commissioner must apply. In determining whether an increase in the rent is unreasonable, the Commissioner is to have regard to:

  • the general level of rents for comparable residential premises in the locality or a similar locality; and
  • any other relevant matter.

The “any other relevant matter” limb is broad. In practice, the Commissioner will consider factors such as the condition of the premises, whether the owner has complied with maintenance obligations, the length of the tenancy, whether recent improvements have been made, and the reason (if any) given for the increase. A large increase on a property with unresolved repair issues is more vulnerable to challenge than a modest increase on a well-maintained property.

The Commissioner has discretion under Section 23(1C) to conduct a hearing, but may also decide the application on the papers without convening a hearing. If a hearing is held, both parties typically have the opportunity to present evidence and respond to the other party’s submissions.

What the Commissioner Can Order

If the Commissioner is satisfied that the increase is unreasonable, Section 23(3) allows the Commissioner to order that the increase be changed to an amount not exceeding a specified figure. This is not an “all or nothing” determination — the Commissioner can reduce the increase rather than disallow it entirely. For example, if you increased the rent by $60 per week and the Commissioner finds $30 per week would be reasonable, the order would cap the new rent at the current rent plus $30.

Under Section 23(4), the Commissioner’s order remains in force until the day on which rent may be next increased under Section 20 — which means the 12-month clock resets from the date of the Commissioner’s order rather than the date of your notice.

The Magistrates Court Pathway (Section 23(5))

If either the tenant or the owner is dissatisfied with the Commissioner’s determination, Section 23(5) provides a pathway to the Magistrates Court. This is an important provision to understand correctly, because it operates differently from the bond appeal pathway under Section 30.

It Is Not an Appeal — It Is a Fresh Determination

A Section 23(5) application to the Court is not a review of the Commissioner’s reasoning. Under Section 23(7), if an application is made under Section 23(5):

  • any order made by the Commissioner under Section 23 is of no effect (unless the application is withdrawn); and
  • the Court is to determine the application as if the Commissioner had not determined an application at all — with the statutory test in Section 23(2), (3) and (4) applied by the Court as if each reference to “the Commissioner” were a reference to “the Court.”

This is a fresh, first-instance hearing on whether the increase is unreasonable — not an appeal examining whether the Commissioner made an error. Both parties effectively start over. The 7-day appeal window under Section 30 (which applies to security deposit determinations under Section 29G) and the Notice of Appeal Form RT03 are not the correct pathway for rent increase matters — Section 23(5) is a separate mechanism with its own 60-day window and its own fresh-determination procedure.

Who Can Apply and When

Unlike the Commissioner application, which is tenant-only, Section 23(5) allows either the tenant or the owner to apply to the Court. Section 23(6) imposes a 60-day limitation: the application must be made within 60 days after the party is notified that the Commissioner has determined the original application.

For a landlord, this matters in two scenarios. If the tenant has succeeded at the Commissioner level and obtained a reduction in the increase, you have 60 days to apply to the Court for a fresh determination. If the tenant has lost at the Commissioner level but you want certainty, you generally would not apply — the Commissioner’s decision already favours you, and an application to the Court would reopen the question for the Court to determine afresh.

How the Court Hears the Matter

The Magistrates Court hearing under Section 23(5) applies the same statutory test as the Commissioner (comparable rents in the locality, and any other relevant matter), but the hearing is more formal. Evidence and submissions are presented in open court, and the Court may consider expert valuation evidence if either party wishes to present it. Costs can be awarded, and Court proceedings carry greater practical and financial risk than the Commissioner pathway.

What the Act Does Not Say About Rent Increases

It is equally important to understand what Section 20 and Section 23 do not do, because several common misconceptions cause self-managing landlords to make avoidable mistakes.

There Is No Rent Cap

Tasmania does not cap rent increases at any percentage, CPI figure, or dollar amount. You can increase the rent by any amount you consider appropriate, subject only to the tenant’s right to challenge the increase as unreasonable under Section 23. The practical ceiling is set by what the market supports and what the Commissioner considers reasonable against comparable properties — not by a statutory cap.

There Is No Requirement to Justify the Increase on the Notice

Section 20 does not require you to give reasons for the increase on the notice itself. You are not legally obliged to explain market rises, council rate increases, insurance costs, or any other driver of the increase. The notice simply needs to specify the new amount and the effective date.

That said, if the tenant challenges the increase, your reasoning and any supporting evidence will become relevant. Landlords who have thought through the basis for the increase and can point to comparable market rents, CPI movement, and any capital improvements made to the property are better positioned than landlords who imposed an increase based on a gut feel.

The Act treats a rent increase as a unilateral act by the owner, effected by written notice. The tenant does not need to sign anything, agree to the increase, or return an acknowledgement. Under Section 20(4), the notice automatically operates to vary the residential tenancy agreement — the increased rent becomes payable from the effective date specified in the notice, regardless of whether the tenant formally agrees.

The tenant’s remedies are (1) to pay the new rent, (2) to challenge it as unreasonable under Section 23, or (3) to end the tenancy using the normal termination process. Refusing to pay the increase without taking steps to challenge it is a breach of the agreement and can lead to a rent arrears process.

A Rent Increase Is Not the Same as a New Agreement

Section 20 is a variation mechanism, not a renewal mechanism. When you issue a valid rent increase notice, the existing agreement continues on all other terms — the bond does not need to be topped up (Section 25(4)(b) allows only one security deposit per agreement, and there is no provision in the Act for the bond to be recalculated when the rent increases), the condition report is not redone, and the fixed term (if any) continues to run on its original timing. Only the rent amount changes.

If you want to renew the lease for a further fixed term AND increase the rent, that is a separate process involving a new or extended written agreement signed by both parties — with the rent increase taking effect under Section 20 timing rules.

Common Mistakes Landlords Make

Giving Notice With Less Than 60 Days Before the Effective Date

This is the single most common error. Section 20(3) requires more than 60 days, which in practice means 61 days or more. A notice giving exactly 60 days does not comply, and neither does a notice dated 60 days before the effective date but actually received by the tenant a day or two later. Always count forward from the day the tenant receives the notice, and always build in a buffer of at least 3–5 extra days for safety.

Forgetting the 12-Month Interval Rule When Renewing a Lease

Self-managing landlords often treat a lease renewal as a blank slate for the rent — assuming that a new fixed term means a new rent baseline. This is wrong. The 12-month interval in Section 20(3) is tied to when the rent itself was last increased or when the tenancy first commenced, not to the lease term. If you increased the rent 8 months ago, you cannot increase it again when renewing the lease today — regardless of whether you and the tenant are signing a fresh fixed-term agreement.

Using the Wrong Form or Language

Tasmania has no prescribed rent increase form, but the notice must contain the two mandatory elements under Section 20(2): the new rent amount and the effective date. Notices that are ambiguous (e.g. “the rent will increase by approximately 5% in the new year”) do not satisfy the section and cannot be enforced. Use a specific dollar figure and a specific calendar date.

Missing the Distinction Between Commissioner and Court Pathways

A surprising number of landlords (and tenants) assume that a challenge to a rent increase follows the same “appeal to the Magistrates Court within 7 days” pathway as a bond decision. It does not. Rent increase challenges go to the Residential Tenancy Commissioner in the first instance, with a 60-day tenant application window under Section 23(1B). The Court pathway under Section 23(5) is a fresh determination with a separate 60-day window, and either party can use it. The Notice of Appeal Form RT03 is for Section 30 bond appeals, not rent increase matters.

Not Keeping Evidence of Comparable Rents

If the tenant applies to the Commissioner to challenge the increase as unreasonable, the Commissioner’s test under Section 23(2) is the general level of rents for comparable properties in the locality. A landlord who has already pulled together evidence of comparable rents (from realestate.com.au, Domain, local agents, or the Property Council of Tasmania) before serving the notice can respond quickly and confidently to a challenge. A landlord who has done no market research is often caught out when the tenant presents a well-prepared comparison.

Failing to Maintain the Property

The Commissioner’s “any other relevant matter” discretion under Section 23(2)(b) is where maintenance problems become rent increase problems. Outstanding repair issues, failure to comply with minimum housing standards, or general neglect of the premises all weigh against the reasonableness of a rent increase. If you have been ignoring repair requests, fix them before you serve the rent increase notice — not after the tenant applies to the Commissioner.

Frequently Asked Questions About Rent Increases in Tasmania

How often can I increase the rent in Tasmania? Rent can be increased no more often than once every 12 months. Section 20(3) requires the effective date of the new rent to be not less than 12 months after the tenancy commenced, was extended or renewed, and more than 12 months after any previous rent increase (or any Commissioner’s order under Section 23(3)). The 12-month clock is tied to the rent itself, not to the lease term.

How much notice do I need to give for a rent increase? More than 60 days’ written notice, under Section 20(3) of the Residential Tenancy Act 1997. The effective date on the notice must be more than 60 days after the day the notice is given to the tenant. The conservative approach is to allow at least 63–65 days to account for delivery time and the strict “more than 60 days” requirement.

Is there a maximum rent increase amount in Tasmania? No. Tasmania does not cap rent increases at any percentage, CPI figure, or dollar amount. However, the tenant has the right to apply to the Residential Tenancy Commissioner under Section 23 for an order declaring an increase unreasonable. The Commissioner will compare the increase against rents for comparable properties in the locality.

Is there a prescribed Government form for rent increase notices in Tasmania? No. Section 20(1) simply requires “written notice” and Section 20(2) requires the notice to specify the new rent amount and the effective date. Unlike some states, Tasmania does not prescribe a specific form. Any written document containing the two mandatory elements and delivered with more than 60 days’ notice is compliant.

Can I increase the rent if my lease doesn’t mention rent increases? Only if there is no written lease at all. Section 20(1) requires either a written agreement that allows for increases, or no written agreement. If your written lease is silent on rent increases, you cannot increase the rent during the term — you would need to wait until the term ends and enter into a new agreement, subject to the 12-month interval rule.

Does renewing the lease reset the 12-month clock? No. Section 20(3)(c) ties the 12-month interval to the last rent increase, not to the lease term. If you increased the rent 8 months ago, you cannot increase it again for another 4 months — even if you and the tenant are signing a brand new fixed-term agreement today.

What happens if the tenant thinks the increase is unreasonable? The tenant can apply to the Residential Tenancy Commissioner within 60 days of being notified of the increase, under Section 23(1) and (1B). The tenant uses the Commissioner’s “Application for unreasonable rent increase” form and must pay the prescribed fee. The Commissioner will consider the general level of rents for comparable properties in the locality and any other relevant matter.

How does the Commissioner decide whether an increase is unreasonable? Under Section 23(2), the Commissioner considers (a) the general level of rents for comparable residential premises in the locality or a similar locality, and (b) any other relevant matter. “Any other relevant matter” typically includes property condition, outstanding repairs, improvements, the reason for the increase, and the length of the tenancy.

What can the Commissioner order if the increase is unreasonable? Under Section 23(3), the Commissioner can order that the increase be changed to an amount not exceeding a specified figure. The Commissioner can reduce the increase rather than disallow it entirely. The order remains in force until the next date on which rent can lawfully be increased under Section 20.

Can I appeal a Commissioner’s decision on a rent increase? Section 23(5) is not strictly an appeal — it is a pathway to the Magistrates Court for a fresh determination. Either the tenant or the owner can apply within 60 days of the Commissioner’s decision. Under Section 23(7), the Court determines the question from scratch as if the Commissioner had never heard the matter. The Section 30 appeal pathway and Notice of Appeal Form RT03 are for bond decisions under Section 29G, not rent increase matters.

Does a rent increase affect the bond? No. The 4-week cap in Section 25(4)(c) applies to the rent payable under the agreement, and Section 25(4)(b) allows only one security deposit per agreement. There is no provision in the Act for the bond to be topped up or recalculated when the rent increases — the bond stays at the amount originally lodged.

What if the tenant refuses to pay the increased rent? A valid rent increase notice automatically varies the agreement under Section 20(4). The increased rent is legally payable from the effective date, regardless of whether the tenant signs anything. If the tenant pays the old amount after the effective date, they are accruing rent arrears — which you can address through the normal rent arrears process (Notice to Vacate on rent arrears grounds after the statutory waiting period, then the Magistrates Court vacant possession process if needed).

Summary

Increasing the rent in Tasmania is a structured, legally prescribed process governed by two short but strict provisions of the Residential Tenancy Act 1997. Section 20 sets the mechanics — written notice, more than 60 days’ notice, 12-month interval, two mandatory content elements (new amount and effective date). Section 23 gives the tenant a challenge mechanism through the Residential Tenancy Commissioner, with a further pathway to the Magistrates Court under Section 23(5) for a fresh determination.

Tasmania has no rent cap, no requirement to justify the increase on the notice, and no prescribed Government form for the notice itself. What it does have is a tight statutory framework where miscounting the 60 days, miscounting the 12-month interval, or producing an ambiguous notice will invalidate the increase entirely. The most common cause of challenged rent increases at the Commissioner level is not the amount of the increase — it is the absence of landlord preparation: no market research, unresolved repair issues, and no documented basis for the new rent.

Self-managing landlords who plan rent increases carefully — researching comparable rents in the locality, confirming the 12-month clock, issuing a precise written notice with a safety margin on the 60-day count, and maintaining the property to the Act’s minimum standards — rarely face a successful challenge. The framework rewards diligence and punishes assumptions.
