A buy-back is a contractual arrangement in asset finance where the seller, or another party, agrees to repurchase an asset at a future date or under agreed conditions.

Also known as: buyback, buy back, buy-back agreement

Key points

  • Common forms: the vendor buy-back, a guaranteed buy-back or residual value guarantee, a sale and leaseback with a repurchase clause, and put/call options.
  • It lets a business free up cash or manage balance sheet outcomes now while keeping a defined route to get the asset back later.
  • Widely used for vehicles, plant and equipment, and fleets where predictable residual values matter.
  • The repurchase price is set by contract: a fixed sum, an indexed amount, market value less a margin, or a percentage of original price.
  • GST can apply to both the sale and the repurchase, and disposing of the asset can trigger a balancing adjustment for tax.

Example

Not to be confused with

Sale and leaseback
a sale and leaseback raises cash by selling and leasing back an asset; a buy-back adds an agreed repurchase mechanism, and the two can overlap
Residual value guarantee (RVG)
a residual value guarantee is one form of buy-back, where a party promises a minimum resale value rather than agreeing to repurchase the asset outright
Manufacturer buy-back
a manufacturer buy-back is the vendor form, where the maker agrees to repurchase its own product; buy-back is the umbrella term

Frequently asked questions

Is a buy-back the same as a sale and leaseback?

Not always. A sale and leaseback is a cash-raising transaction where you sell an asset and lease it back. A buy-back specifically includes an agreed mechanism for the asset to be repurchased. The two overlap when a sale and leaseback contract also includes a repurchase option at the end of the lease or at a set point.

How is the buy-back price set?

By contract. It can be a fixed amount, an indexed amount, a depreciation schedule, market value less an agreed margin, or a percentage of the original price. Ask for worked examples showing the cash and GST effect of the formula, and negotiate the right to an independent valuation if market value is the trigger.

Do you pay GST on a buy-back?

Usually, yes. The initial sale typically attracts GST if the seller is registered, and the later repurchase can attract GST again unless an exception or adjustment applies. Both legs can also have income tax and capital gains consequences. Document the GST treatment in the contract and confirm it with the ATO's guidance or your tax adviser.

What happens if the buyer becomes insolvent before the buy-back?

If the party that agreed to repurchase the asset is insolvent, you may end up as an unsecured creditor with no practical way to enforce the buy-back. Protections negotiated up front, such as escrow, a bank guarantee or a security interest registered on the PPSR, are what put you in a stronger position.

Is a residual value guarantee the same as a buy-back?

A residual value guarantee is a type of buy-back mechanism. Instead of agreeing to repurchase the asset outright, a party guarantees a minimum resale value at the end of the lease and pays any shortfall if the market value comes in lower. It limits residual risk and is common in fleet programs.
