What is a body corporate sinking fund?

A body corporate sinking fund is a long-term reserve fund used to pay for major capital works on common property in a strata scheme. It exists to ensure that large, infrequent expenses can be planned for and funded over time, rather than requiring sudden financial contributions from owners.

Unlike the administrative fund, which covers day-to-day running costs, the sinking fund is focused on future expenditure. Think of it as a structured savings plan for the building itself.

In practical terms, it ensures the body corporate has money available when significant repairs, replacements, or upgrades are required.

How the sinking fund is funded

The sinking fund is primarily funded through regular contributions, commonly known as levies, paid by all lot owners within the body corporate.

Unlike one-off charges, the sinking fund is planned using a long-term financial model called a sinking fund forecast. This forecast estimates the timing and cost of major capital works over a set period (often 5 of 10 years) and determines how much needs to be collected each year to meet those future obligations.

Each owner contributes based on their Contribution Schedule Lot Entitlement (CSLE), which is recorded in the Community Management Statement (CMS). This means owners do not pay an equal share, but rather a proportionate share based on their unit entitlement in the scheme.

What the sinking fund is used for

The sinking fund is specifically used for capital expenditure, meaning works that extend the life of an asset or replace it entirely.

Common examples include external repainting of buildings, roof replacement or major roof repairs, lift upgrades or full replacements, resurfacing driveways and basements, and replacing major infrastructure such as pipes, gates, or lighting systems. It may also be used for refurbishing shared facilities such as pools, gyms, or BBQ areas.

These are not routine maintenance items. They are planned, larger-scale projects that occur periodically over the life of a building.

What the sinking fund does not cover

The sinking fund is not used for ongoing operational expenses such as cleaning, gardening, insurance, utilities, and management fees. These are covered by the administrative fund instead.

The key distinction is that the sinking fund deals with long-term asset preservation, while the administrative fund deals with day-to-day operations.

Why sinking funds are important

A properly managed sinking fund plays a critical role in maintaining both the building and the financial stability of owners.

Because major works are expected in all buildings over time, the sinking fund allows costs to be spread across many years. This reduces the likelihood of sudden, large special levies when significant work becomes necessary.

When the sinking fund is adequately funded, bodies corporate can plan ahead, carry out works proactively, and avoid deferred maintenance that can lead to more expensive repairs later.

In simple terms, it protects both the building’s condition and owners’ financial predictability.

How sinking fund levies are calculated

Sinking fund contributions are not arbitrary. They are based on a structured financial plan known as a sinking fund forecast.

This forecast typically looks 10 years or more into the future and identifies:

  • What capital works are likely to be required
  • When those works are expected to occur
  • How much each project is likely to cost

The total projected cost of these works is then spread across time and funded through annual levies.

Each owner contributes according to their Contribution Schedule Lot Entitlement, which is set out in the Community Management Statement. This ensures contributions are proportionate to each lot’s share in the scheme.

How the sinking fund changes over time

A sinking fund forecast is not static. It is regularly reviewed and updated to reflect real-world changes such as construction cost inflation, changes in building condition, updated engineering advice, or unexpected capital works.

Because of this, sinking fund levies may increase or decrease over time depending on what the building needs and how cost estimates change.

This is normal and reflects the evolving nature of building maintenance planning.

What happens if the sinking fund is not sufficient?

If a sinking fund is underfunded, the body corporate may not have enough money available when major works are required. In these situations, the most common outcome is a special levy, where owners are asked to contribute additional funds outside the regular budget.

This can place financial pressure on owners and may also delay important works if funding is not immediately available. In some cases, it can also result in reactive rather than planned maintenance, which is typically more expensive in the long term.

Sinking Fund FAQs

The administrative fund covers day-to-day operational costs such as cleaning, insurance, and maintenance. The sinking fund is used for long-term capital works like roof replacement, repainting, and major infrastructure upgrades.

The sinking fund is forward-planned. Contributions are collected over time so that when major works are needed in the future, the funds are already available.

Your levy is based on a sinking fund forecast and your Contribution Schedule Lot Entitlement (CSLE), which determines your share of costs within the body corporate.

Yes. Levies can increase due to rising construction costs, updated forecasts, or additional capital works being identified for the scheme.

If the sinking fund does not have enough money to cover required capital works, the body corporate will usually address the shortfall in one of two ways.

Where the works are not urgent, the shortfall may be recovered over time by increasing future sinking fund levies. If the works are urgent or cannot be delayed, the body corporate will typically raise a special levy from owners to fund the shortfall immediately.

Can Owners Participate in Body Corporate Committee Meetings?

If you are not an elected committee member, you can usually attend body corporate committee meetings as an observer. However, you do not have automatic rights to speak or vote. Your level of participation depends on the meeting structure and approval from the committee.
