Section 198 Elections
Explained

The critical rules for property transactions — and when they don't apply.

What Is a Section 198 Election?

Section 198 of the Capital Allowances Act 2001 provides a mechanism for allocating capital allowances between a buyer and seller in property transactions. It allows the parties to agree how unclaimed allowances should be split.

The election must be made within 2 years of the property sale and is binding on both parties.

When Does Section 198 Apply?

A Section 198 election is relevant when:

  • A commercial property is sold
  • The seller had unclaimed capital allowances attached to the property
  • The buyer wishes to claim those allowances

What Can Be Allocated?

Through a Section 198 election, the parties can:

  • Transfer all unclaimed allowances to the buyer
  • Split the allowances between buyer and seller
  • Leave allowances with the seller (though this is rare)

The Critical Clarification: What It Does NOT Apply To

This is where many accountants go wrong. A Section 198 election is only relevant to property purchases where there is a seller to make an election with.

Section 198 Does NOT Apply To:

  • Leasehold Improvements — Where a tenant has funded improvements to a rented property. There is no "seller" — the tenant owns the embedded allowances.
  • Renovation or Conversion Costs — Where a property owner has renovated or converted a building. The allowances belong to them alone.
  • New Build Construction — Where the property was constructed by the owner. Again, no seller exists.
Key Point: In these scenarios, there is no Section 198 election to make. The person who incurred the expenditure owns 100% of the allowances.

Practical Implications

When advising clients on property transactions:

  • For buyers: Check if the seller has unclaimed allowances and negotiate accordingly
  • For sellers: Consider whether to retain or transfer allowances to maximise value
  • For leasehold improvements: Don't wait for a Section 198 election — it doesn't apply

Common Mistakes to Avoid

  • Assuming Section 198 applies to all property transactions
  • Waiting for a seller to make an election on leasehold improvements
  • Failing to identify unclaimed allowances before a property sale
  • Missing the 2-year deadline for making an election
