Best Time to Contact HMRC

Many people experience long waiting times when calling HMRC. To improve your chances of speaking to an adviser quickly:

• Call shortly after the phone lines open.
• Tuesday to Thursday are usually quieter.
• Avoid Mondays where possible.
• Avoid lunchtime.
• Try to avoid calling during January if your enquiry is not urgent, as this is the busiest period for Self Assessment.

If your enquiry can be completed online, this is often the fastest option.

These include:

• Personal Tax Account

Instead, they recommend using:

• Secure online forms
• Personal Tax Account
• Business Tax Account
• Live Chat
• Telephone support

This helps protect your personal information and ensures enquiries are handled securely.

HMRC Postal Address
