Let me be absolutely clear with the House that we are not talking about quarterly tax returns. This is not about having to do a full tax return but about reporting; indeed, the purpose of the changes is ultimately to reduce the burden on businesses. It will start to be introduced in 2018. I hope that we will set out further information about the plans in the coming weeks. The intention is to ensure that we reduce the tax gap and, ultimately, help businesses to comply with the tax system.
