Came to file a clients VAT return for 30th June - they are claiming exemption. The old portal shows no VAT returns are due even though neither the client or ourselves has signed up for MTD . When I call VAT helpline I am told they cant talk to me even though we have dealt with the clients for 20 years and when I write in to HMRC I have to either ask my MP to intervene or threaten them with court action. The last letter sent in took 102 days for HMRC to reply too. Any ideas as I am concerend HMRC might charge a penalty if the VAT is not paid plus the time one small firm are taking on this MTD initiative is getting worrying. Any constructive help ?
