I've seen other threads on this but just wanted a definitive answer. I was waiting to submit my vat reclaim until the building control sign off, this will likely be within the next two weeks. However, I have a VOA letter with 'effective date of alteration: 24th Jan 23'. Therfore, can I wait until my completion cert before submitting the vat claim or must I do it before 3 months is up from VOA letter? I'd need to post it off next week if this is the case and would miss out on about £1k of vat on stuff I was planning on buying, but it's better than potentially being messed around by HMRC over £40k of vat.
Many thanks
