HMRC has a useful online tool to help agents and taxpayers know when they can expect to receive a reply from HMRC regarding a query or request that they have made. The online tool is updated weekly.

The online tool has recently been extended to include information about employers’ PAYE and National Insurance.

The full list of taxes the tool can be used for are as follows:

• Child Benefit
• Corporation Tax
• Employers’ PAYE
• Income Tax
• National Insurance
• Self-Assessment
• Tax credits
• VAT

Agents can also check how long it will take HMRC to:

• register you as an agent to use HMRC online services;
• process an application for authority to act on behalf of a client; and
• amend your agent details.

The online tool can be accessed at the following address, and you do not have to be logged in to receive an answer: https://www.tax.service.gov.uk/guidance/Check-when-you-can-expect-a-reply-from-HMRC/start/are-you-an-agent
