Quick answer
A self assessment workflow is a standardised process for tracking every client's personal tax return from information request through to submission, applied consistently across the whole client bank ahead of the 31 January online filing deadline. It replaces a single busy-season spreadsheet with an ongoing, trackable pipeline.
What is a self assessment workflow and why does it matter for UK practices?
It is the repeatable structure that moves every self assessment client from data request to filing, visible across the whole practice rather than tracked informally.
The online Self Assessment filing deadline is 31 January, and for many practices this creates the single busiest period of the year. A workflow that starts in April, rather than in December, spreads the workload and reduces the number of clients still outstanding as January closes in.
Each client needs the same broad stages: information requested, information received, return prepared, return reviewed, return approved by the client, return filed. Tracking that consistently for hundreds of clients is difficult without a shared system.
Why does self assessment workflow break down every January?
Everything starts too late
Requests for information often go out in November or December, leaving little time to chase non-responsive clients before the deadline.
Status is tracked in someone's head
Without a shared view, only one person may know which clients have responded and which are still outstanding.
Chasing is inconsistent
Some clients get chased repeatedly while others slip through simply because nobody happened to follow up with them.
Staff are overloaded unevenly
Without visibility of who holds how many outstanding returns, workload piles up on some staff while others have capacity.
Late clients cause a January pile-up
Clients who provide information late compress the preparation and review time into the final days before the deadline.
What does a poor self assessment process cost an accounting firm?
The direct cost is the automatic penalty for a missed 31 January deadline, and the indirect cost is a stressful January that risks staff burnout and rushed, error-prone work.
HMRC applies an automatic penalty for a Self Assessment return filed after 31 January, regardless of whether tax is owed, which makes even a single missed client a real cost.
The bigger cost for many firms is the human one: an unmanaged rush in January leads to burnout, mistakes and a January that everyone dreads rather than a period that runs to plan.
How do you run a self assessment workflow? Step by step
- 1
Start requesting information early
Send the first information request well before the busy period, ideally from April, rather than waiting until the final quarter of the year.
- 2
Track status for every client
Record where each client stands, from not yet requested through to filed, so nothing depends on memory.
- 3
Chase on a fixed schedule
Set a consistent reminder cadence for clients who have not responded, rather than chasing only when someone remembers.
- 4
Prioritise complex returns early
Identify clients with more complex affairs and start their preparation earlier, leaving simpler returns for closer to the deadline.
- 5
Distribute workload evenly
Spread outstanding returns across the team based on actual capacity rather than letting them accumulate with whoever usually handles a client.
- 6
Get client approval before filing
Send the completed return for client approval with enough time left to file, rather than seeking approval on the final day.
- 7
File and confirm
Submit the return and record confirmation of filing against the client so the job can be closed with certainty.
How does Remindoo help with self assessment workflow?
Remindoo's recurring tasks and reminders let you set the self assessment cycle to start well ahead of January, so information requests go out in good time rather than at the last minute. Task filters give a live view of every client's status across the whole practice, so partners can see exactly how many returns are outstanding and who holds them, rather than asking around. Bulk task actions make it possible to chase, reassign or prioritise groups of clients at once when the deadline is approaching. Task and subtask templates keep the steps consistent for every client, and the client timeline records every interaction so handovers between staff during the busy period do not lose context. Detailed task creation captures priority so complex returns can be flagged and started earlier than straightforward ones. Try Remindoo free for 60 days ahead of your next January to see the difference a tracked pipeline makes.

Frequently asked questions
When is the Self Assessment online filing deadline?
The online Self Assessment deadline is 31 January following the end of the tax year, and returns filed after that date attract an automatic penalty from HMRC regardless of whether tax is owed.
How early should information requests go out?
Many practices start requesting information from April, as soon as the previous tax year has ended, to give clients the maximum amount of time to respond before the busy period.
Does Remindoo submit the return to HMRC?
No, Remindoo manages the workflow, deadlines and client communication around self assessment; it does not prepare tax returns or submit them to HMRC.
Can I see which staff member holds the most outstanding returns?
Yes, task filters and employee reporting let you see how outstanding work is distributed across the team, so you can rebalance before the deadline gets close.
Is there a free trial before the busy season?
Yes, Remindoo offers a 60-day free trial, which is enough time to set up and run a self assessment workflow before your busiest weeks arrive.
What happens to MTD for Income Tax and self assessment workflow?
Making Tax Digital for Income Tax becomes mandatory from April 2026 for qualifying income over £50,000, which will add quarterly reporting alongside the annual return, making an organised workflow even more important.

Why recording every task matters in an accountancy practice
Accounting firms run on deadlines: VAT returns, payroll, confirmation statements, accounts and Self Assessment. Recording every job as a task, with an owner and a date, is the simplest way to make sure nothing is missed.
Avoid penalties
HMRC and Companies House charge penalties for late filing. A task for every deadline, with an internal date before it, gives the team a buffer.
Nothing depends on memory
Recorded tasks mean work continues when someone is off sick, on leave or has left the firm.
Consistent quality
Subtask checklists make every job follow the same steps and reviews, whoever does the work.
Visibility for managers
Filters by owner, status and deadline show at a glance what is late, what is due and who needs help.
Practical tips from UK practice
- Set an internal deadline two to four weeks before every statutory deadline.
- Use recurring tasks for repeat work such as VAT, payroll and bookkeeping.
- Break larger jobs into subtasks, including a review step.
- Comment on the task instead of by email, so the history stays with the work.
