Rent Increase Laws in Tasmania: The 12-Month Rule

To combat volatile rent spikes and protect housing affordability, the Tasmanian Government maintains strict regulations over both the frequency and mechanism of rent increases under the Residential Tenancy Act 1997 (RTA).

The 12-Month Minimum Timeframe

In Tasmania, rent can only be legally increased if it has been at least 12 months since the start of the lease or since the last rent increase took effect.

A landlord cannot increase the rent every six months, regardless of whether the tenant signs a series of short, six-month fixed-term leases. The 12-month rule supersedes the lease duration.

When Can Rent Be Increased?

The legal ability to increase rent heavily depends on whether the lease is fixed-term or periodic, and whether the lease agreement explicitly allows for an increase.

Fixed-Term Leases

You cannot increase the rent during an active fixed-term lease unless the written lease agreement contains a specific clause that allows for an increase and states precisely how that increase will be calculated (e.g., tied to the CPI, or a flat dollar amount).

If you use a standard real estate institute lease without adding an escalation clause, the rent is permanently locked in for the entire fixed duration. When the fixed term is ending, you can offer a new lease renewal at a higher rate, provided you observe the 60-day notice period and 12-month limit.

Periodic (Month-to-Month) Leases

If the lease has transitioned to a non-fixed term (periodic) lease, or if there was never a written lease to begin with, the landlord has the legal right to increase the rent, provided 12 months have passed.

The Statutory Notice Period

Whenever a landlord increases the rent, they must provide the tenant with formal, written notice.

The landlord must provide 60 clear days' written notice before the new rental rate takes effect.

The written notice must explicitly state:

1. The exact amount of the new, increased rent.
2. The exact date on which the new rent will begin.

Note on "Clear Days": If you are posting the notice via mail rather than handing it to the tenant directly, you must add additional days for postage delays to ensure the tenant receives a full 60 calendar days between receiving the notice and the day the rent rises.

Disputing an Unreasonable Rent Increase

Tasmania allows tenants to formally dispute a rent increase if they believe it is excessive and out of step with the current market for comparable properties in the area.

A tenant can apply to the Residential Tenancy Commissioner (through CBOS) to have the rent increase reviewed. They must file this application within 30 days of receiving the 60-day rent increase notice. If the Commissioner deems the increase unreasonable, they can issue a binding order halting or lowering the increase.

Automating Tasmanian Compliance

Managing 60-day notice horizons and meticulously tracking the 12-month anniversary across a diverse portfolio is a logistical hurdle. A rent increase notice sent on day 59 instead of day 60 is legally invalid. Landager tracks the exact date of every rent increase at the property-level, blocking illegal mid-term increases in your ledger and automatically generating the mathematically precise, 60-day written notices exactly when the RTA allows.
