As a tax agent must I create both client and agent copies when using Ftax VAT and Ftax Cashbook?

No. There are several ways the Ftax MTD forms may be used:

1. You may advise your client to purchase the non-agent Ftax VAT or Ftax Cashbook package. These feature a single copy to be used solely by the client.
2. If you have purchased either an Ftax Agent VAT or an Ftax Agent Cashbook package then you may generate both the agent and client copies before securely transferring the latter to your client using the password provided. The two copies are designed to be ‘sync’ed when in use so that the agent and client view the same data. Either may complete the form or submit to HMRC. Typically, the client may enter the VAT data, (either directly into the Ftax Cashbook, or into their own spreadsheet before using the Ftax VAT Link to transfer the data to the Ftax VAT pdf form), under the supervision of the agent.
3. If you have purchased either an Ftax Agent VAT or an Ftax Agent Cashbook package then you may generate the agent copy only. You should do this if you plan to complete and submit the form on behalf of your client.
4. If you have purchased either an Ftax Agent VAT or an Ftax Agent Cashbook package then you may choose to only generate the client copy before securely transferring this form to your client using the password provided. The client would then be able to enter all VAT data and submit to HMRC themselves.
