HMRC self assessment helpline 0300 200 3310
In a recent development, HMRC caused a stir by announcing the closure of their self-assessment helpline for six months of the year, starting from April this year. However, the decision was temporarily paused less than a day later following a significant backlash.
The self-assessment helpline receives around 5m calls each year, with nearly 4m people staying on through the recorded messages to speak to an HMRC adviser, according to the HMRC quarterly performance figures.

If you experience any issues while using HMRC's online services, you can contact their online services helpdesk.
