HMRC Contact Details 2026: Full List for Self Assessment, PAYE, Corporation Tax, CIS & Debt Collection
HMRC provides dedicated helplines and online services for every type of tax and query. Whether you need to speak to someone about Self Assessment, Corporation Tax, PAYE, the Construction Industry Scheme (CIS), or debt collection, having the correct phone numbers, opening hours, and direct GOV.UK links saves time and avoids frustration.
Updated March 2026: All main HMRC helplines remain free from UK landlines and mobiles (standard rates apply). Most lines now have improved callback options and extended online self-service, but phone waiting times can still be long during peak periods (January and July). Always have your UTR, National Insurance number, or Company Registration Number ready when you call.
At Filing Accounts, we regularly contact HMRC on behalf of clients for Self Assessment, Corporation Tax, PAYE, CIS, and debt queries. If you need help contacting HMRC or resolving any tax issue, contact us today — we can assist you directly and often get faster results.
