Practical guide

How to spend less time on hold to HMRC

Four things that genuinely work — from timing and line choice to online alternatives and full hold automation.

Call at the right time

Queue length on the HMRC Agent Dedicated Line varies enormously by day and hour. The quietest windows, based on verified calls:

  • 8:00–9:00am, Tuesday to Thursday — consistently the shortest queues
  • Avoid Mondays — the highest call volume of the week, as queries build over the weekend
  • Avoid post-bank-holiday mornings — queues surge on the first working day back
  • Avoid 12–2pm — call volume picks up as advisers break for lunch, increasing per-adviser load

Use the Agent Dedicated Line, not the public line

The HMRC Agent Dedicated Line (0300 200 3311, 8am–6pm Mon–Fri) is shorter, faster, and staffed by advisers who understand agent queries. The public Self Assessment line (0300 200 3310) is not for agent use — hold times on the public line routinely exceed 60 minutes and advisers are not briefed for third-party interactions.

For debt and Time to Pay matters, use the Debt Management agent line: 0300 200 3887.

Use HMRC online services for tasks that do not need a call

A surprising number of agent tasks can be completed online without picking up the phone:

View client tax positions Check SA and PAYE balances, coding notices, and payment history through Agent Services Account
Submit and amend returns File SA100, SA800, and employer returns; amend in-year via Government Gateway
Manage authorisations Create, view, and remove client authorisations (64-8 equivalent) online
Claim repayments Request SA repayments and track their status without a call in most cases
PAYE coding notices View and query P2 coding notices for clients through the agent dashboard
HMRC webchat Webchat is available for some query types on GOV.UK — check before dialling

That said, complex queries — account corrections, disputed penalties, formal appeals, or anything requiring HMRC to action a change — still require a phone call. No online route substitutes for speaking to an adviser in those cases.

Use hold automation for calls that cannot be deferred

When a call is necessary and you cannot afford to wait, holdNavigator handles the hold. It dials 0300 200 3311, navigates the IVR menus, sits in the queue, and rings your phone when an adviser answers. You join the call before the security check and answer it yourself — holdNavigator exits immediately once you are connected.

You get your time back. The call is yours. From £10.

holdNavigator never hears, records, or stores your call with HMRC. It disconnects the moment you are connected to the adviser. Client data is never at risk.

What holdNavigator does not do

holdNavigator is a queue automation tool, not a call service. It does not:

You make the call. We hold the phone.

Try holdNavigator

Dial HMRC, navigate the menus, and hold — without touching your phone. From £10 per call. No subscription required to start.
