This is possible. The companies need to be set up as a subsidiary.
One way to check whether this is already done:
Click **Access Digital Tax** and scroll down to your data sources.
Next to your data source, click the **pencil** icon and select your data source.
If your company has been set up as a subsidiary, you can select both companies for the data source so that both are covered under the one VAT return.
If this is not the case our support team will need to investigate, run scripts or liaise with the hosting or development teams. For help contacting us, see our Get support in Access Digital Tax.
