Is there a time limit for applying for a refund on Stamp Duty Land Tax on an Uninhabitable Property bought in February 2022? We paid Stamp Duty at the time of purchase at the higher rate due to owning a couple of other buy-to-let properties and we were unaware that due to the delict/uninhabitable state of the property it should not have been classified as a residential property. Despite research, I cannot establish if there is a time limit for applying for a refund. Please can you help?
