Are abortive property purchase costs tax deductible for a limited company?
Short version. A limited company cannot treat every cost of a failed buy-to-let purchase as a deductible rental expense. Abortive capital acquisition costs retain their capital character for tax. Qualifying costs of arranging borrowing can fall under separate loan-relationship rules, even if the mortgage never completes. The purpose of each cost matters.
1. Are legal fees and a buyer's premium deductible if a property purchase falls through?
Costs directly attributable to acquiring an investment property, such as a buyer's premium or conveyancing fees, are normally capital for tax. Failure to complete does not turn them into revenue expenses. See HMRC BIM35325 on abortive expenditure.
Do not classify every professional fee by its name alone. Acquisition work, borrowing arrangements and preliminary investment appraisal can have different treatment. HMRC CTM08260 distinguishes investment appraisal from costs after deciding to acquire a particular investment. It does not make every unsuccessful purchase cost a management expense or an allowable capital loss.
2. Can a company claim mortgage application, valuation and broker fees?
Fees incurred directly in arranging the company's borrowing can qualify under the loan-relationship rules. This may include arrangement fees, broker fees and a valuation required for the proposed loan. A survey obtained for the purchase itself is not automatically a borrowing expense.
HMRC CFM33060 explains the qualifying-expense conditions and CTA 2009 section 329: qualifying abortive borrowing expenditure can be taken into account even when the company never becomes party to the loan. General investment advice does not qualify merely because borrowing was contemplated.
For a company with no trade, qualifying financing debits are non-trading loan-relationship expenses. If they exceed the relevant credits, the result is a non-trading loan relationship deficit, not a property loss. Read HMRC CFM32030 and our guide to non-trading loan deficits.
3. Why can the accounts show a loss but the property tax calculation show none?
An expense written off in the accounts does not necessarily qualify for a tax deduction. A tax add-back reverses the deduction in the computation without deleting the expense from the accounts. Moving a financing cost to the finance heading changes its classification, not the total accounting loss.
If the first property was never acquired or let and the rental business never began, entering the costs as ordinary rental expenses can create the wrong category of loss. Read can a company claim a property loss before letting starts? A nil Corporation Tax bill does not establish that the loss classification is correct.
4. How to enter abortive property costs in the filing wizard
SimpleCompanyTax provides separate rent and expense rows, a property add-back field and finance entries. We provide filing software, not accounting or tax advice. You choose the treatment from your circumstances. The following is an example of recording that choice, not a finding that your costs qualify.
Suppose a company has no rent, £4,200 of acquisition costs written off in the accounts and £450 of fees it has classified as qualifying borrowing expenses:
| Wizard field | Example entry |
|---|---|
| Other charges, within property expenses | £4,200 |
| Property disallowable expenses, under Tax adjustments → Property tax treatment | £4,200 |
| Interest payable and similar charges | £450 |
| Your property tax base (optional override) | Leave blank to use the calculation |
Remove the £450 from any other expense total when moving it to finance. Property disallowable expenses covers non-deductible costs already entered in the property expense rows. It is not limited to entertaining or fines. The separate trading Disallowable expenses and Qualifying pre-trading expenditure rows are hidden for a company with no trade.
With no other figures or adjustments, this example retains a £4,650 accounting loss, gives a nil calculated property tax base and a £450 non-trading financing deficit. If the company instead decides all £4,650 is non-deductible, both property Other charges and Property disallowable expenses would be £4,650, with none of these costs in the finance field. Failure to qualify as a borrowing cost alone does not decide its alternative treatment.
Check the calculation for each return when accounts cover more than 12 months. Box 795 reports the financing deficit arising in that return. Box 805 reports a property loss arising, while box 250 reports property loss relief used. Carry-forward balances are separate. See the HMRC CT600 guide.
New filings use the separate rent and expense rows described here. If an older saved draft only shows a net property figure, do not put a gross expense total into it. See property income and losses or contact support for help with the available fields.
