Every UK accounting practice ends up spending hours a week logged into HMRC’s agent services account or the Companies House portal, and very little of that time involves technical judgement. If you’re weighing up whether to outsource HMRC and Companies House admin, the short answer is that most of the routine portal work can be safely delegated, as long as it’s handed to someone who understands agent authorisation, filing deadlines, and where the real compliance risk actually sits.
This guide sets out exactly which portal tasks are safe to delegate, which ones should stay with a qualified accountant, and what a well-run handover looks like once you decide to make the switch.
What HMRC & Companies House Portal Admin Actually Involves
Day-to-day portal admin covers a wide range of small, recurring tasks, including:
- Submitting VAT and PAYE returns
- Checking client account statuses
- Updating agent authorisations
- Filing confirmation statements
- Tracking correspondence and chasing up queries HMRC or Companies House raise after submission
None of it is complicated in isolation, but it adds up to a steady stream of low-value, high-frequency work that competes for the same hours as advisory client work.
Why This Work Piles Up on Senior Staff
In smaller practices, portal admin often defaults to whoever has agent access, usually a partner or senior accountant, simply because setting someone else up with the right permissions feels like more hassle than doing it themselves. Over a year, that habit quietly eats into billable hours that should be going toward advisory work, client meetings, and the parts of the practice that actually grow fee income.
What Can Be Safely Delegated vs What Needs a Qualified Accountant
The dividing line is judgement, not complexity.
Tasks That Can Be Delegated
- Submitting a return that’s already been reviewed and approved
- Checking a filing status or account balance
- Updating a client’s registered details
- Following up on an outstanding HMRC or Companies House query
Tasks That Should Stay With a Qualified Accountant
- Deciding how a transaction should be treated
- Resolving a technical query with HMRC
- Signing off a return before it’s submitted
A Worked Example
A typical split might look like this: an administrator checks that a client’s VAT return has been accepted, chases a missing Companies House filing receipt, and updates a registered office address, all without needing sign-off each time. If HMRC queries a figure on that VAT return, that query is flagged straight back to the accountant rather than answered independently. Good HMRC and Companies House portal admin support is built around that split, not around replacing accountant sign-off.
The Risk of Getting Portal Admin Wrong
Missed confirmation statement deadlines, lapsed agent authorisations, or an unanswered HMRC query can turn into penalties fairly quickly, and penalties are exactly the kind of work that then needs an appeal for late filing or payment to fix. A consistent portal admin process is one of the cheapest ways a practice can avoid that entire category of avoidable problems.
How Outsourcing HMRC & Companies House Admin Works in Practice
What a Typical Handover Looks Like
An outsourced administrator is set up with agent access inside your existing HMRC and Companies House logins, with no new software, no separate portal for your team to check. Submissions, status checks, and correspondence tracking happen on a set schedule, with anything outside normal process flagged back to the practice rather than actioned independently. It’s the same split used for client onboarding admin: the repeatable steps are handled end-to-end, and anything needing professional judgement is routed straight back to the practice.
Staying in Control of What Gets Submitted
Access can be set up so that anything outside a defined list of routine tasks needs a quick sign-off before it goes anywhere near HMRC or Companies House, so the practice always knows what’s been submitted and when.
People Also Ask About HMRC & Companies House Portal Admin
Can an agent submit accounts to Companies House on a client’s behalf?
Yes. Once an agent is properly authorised and set up with the correct access, they can file confirmation statements, update company details, and submit accounts through the Companies House portal on behalf of a client.
How do I authorise an agent with HMRC?
Agent authorisation is set up through HMRC’s agent authorisation process, which links a client’s tax records to an agent’s HMRC account so the agent can view and manage their affairs online.
What happens if a Companies House confirmation statement is filed late?
Companies House can take enforcement action against a company that fails to file its confirmation statement on time, including striking the company off the register in persistent cases, which is why a reliable tracking process matters more than it might first appear.
Does outsourcing portal admin mean giving up control of client accounts?
No. Access is granted, monitored, and can be revoked by the practice at any time, and every action taken should be visible and reportable; the practice stays in control of what gets submitted and when.
