Readers are reminded that HMRC have developed a number of toolkits across a range of technical areas which can be used to assist agents when completing their clients’ income and corporation tax Returns. The latest toolkits to be updated are the Small Profits Rate and Marginal Relief Toolkits.

These toolkits are intended to provide guidance on areas of error that HMRC frequently see in returns and set out the steps that agents can take to reduce the incidence of those errors.

Therefore the toolkits should help to:

• ensure that returns are completed correctly, minimising errors
• focus on the areas of possible error that HMRC consider key
• demonstrate reasonable care

Before using the toolkits it is recommended that Agents read the essential information guide on using the toolkits and reasonable care under HMRC's penalty system.
