If you need to get in touch with HMRC, here are all the numbers you need – albeit HMRC have closed their Self Assessment helpline, to the public, until September 2023… but thankfully Accountants & Tax Agents still have acess to an Agent Line and all other HMRC helplines are open

Getting in touch with HMRC can seem daunting which is why many people opt to engage with an accountants or tax adviser to do this leg work for them. Here is our guide with details of who to call at Gov.UK to speak to about your tax affairs
