Busy season burnout: how accountancy firms can protect their teams
For many accountancy firms, the months leading up to the 31 January self-assessment deadline are the most demanding of the year. Long hours, back-to-back deadlines and pressure from clients can push even the most resilient teams to the point of burnout. And the effects often carry on well into spring.
Busy season is predictable, so burnout doesn’t have to be. This article sets out practical steps firms can take before, during and after the peak to protect their people. For a wider look at the pressures facing the profession, read our guide to mental health in accountancy.
Key takeaways
January is a pressure point: 74% of accountants say they feel stressed about returning to work in January (Caba, 2026).
Burnout is becoming normalised: 41% of accountants believe burnout is now a normal part of workplace culture (Caba, 2026).
Deadlines are stacking up: Making Tax Digital quarterly updates now fall due on 7 February, a week after the self-assessment deadline, for many self-employed and landlord clients.
Planning makes the biggest difference: Resourcing, realistic targets and clear priorities set before busy season starts reduce pressure later.
Recovery matters: Time to rest after the peak helps prevent stress turning into long-term absence.
What is busy season burnout?
Burnout is a state of physical and emotional exhaustion caused by prolonged stress. In accountancy, it often builds during busy season, when people work long hours for weeks at a time with little chance to recover between deadlines.
Unlike a single stressful day, burnout develops gradually. Someone who starts busy season motivated and productive can end it exhausted, detached from their work and making more mistakes than usual. Without support, it can lead to longer-term mental health problems and time off work.
Why busy season is getting harder
Stacked deadlines
The self-assessment deadline of 31 January has always been the main peak. For many practices, Making Tax Digital for Income Tax has added more. Since 6 April 2026, sole traders and landlords with qualifying income over £50,000 must send quarterly updates to HMRC. The update covering the period to 5 January is due by 7 February, giving teams only days to recover after the self-assessment deadline.
Client behaviour
Late paperwork, last-minute questions and clients who leave everything until January concentrate the workload into a few weeks. Difficult conversations about tax bills add to the emotional strain.
Stretched teams
Recruitment challenges mean many firms go into busy season with fewer people. The same volume of work spread across a smaller team means longer hours for everyone.
The return from the festive break
Many accountants go straight from the holidays into the busiest weeks of the year. Caba research found that 74% of accountants feel stressed about returning to work in January.
Before busy season: plan ahead
The best time to tackle busy season burnout is in the autumn, before the pressure builds.
Review capacity early: Compare expected workload with the hours your team can realistically deliver. Use temporary staff, outsourcing or support from other teams where needed.
Chase client information early: Set clear deadlines for clients to send records, and follow up from October onwards to avoid a January rush.
Agree priorities: Make it clear which work must be finished by each deadline and what can wait.
Set expectations on hours: Agree what is reasonable, and remember that the Working Time Regulations limit average weekly working hours to 48 unless an employee has chosen to opt out.
Remind staff about support: Make sure everyone knows how to access confidential help before they need it.
During busy season: protect your people
Monitor workloads and hours: Check in regularly on who is working the longest hours, especially junior staff and high performers who may not speak up.
Protect breaks and rest: Encourage people to take proper breaks and leave on time where possible. Workers are entitled to a 20-minute break when they work more than 6 hours, and to 11 hours’ rest between working days.
Keep communication open: Short, regular team check-ins help managers spot problems early and redistribute work before someone reaches breaking point.
Lead by example: If partners and managers send emails late at night and never take breaks, staff will feel they must do the same.
Recognise effort: A simple thank you, small rewards or team lunches go a long way during the hardest weeks.
Watch for warning signs: More mistakes, irritability, withdrawal and exhaustion are signs that someone may need support.
After busy season: build in recovery
Many firms focus on getting through the deadline and forget about what comes next. Without time to recover, the stress of one busy season carries into the next.
Encourage time off: Prompt staff to book leave once the peak has passed, and consider time off in lieu for extra hours worked.
Ease back gradually: Avoid scheduling another heavy project straight after the deadline where you can.
Hold a review: Ask your team what worked, what didn’t and what would make next year easier. Use the feedback to plan ahead.
Check in individually: Some people will feel the effects of busy season weeks later. A private conversation can help identify anyone who needs more support.
How managers can spot burnout
Managers play a key role in noticing when someone is struggling. Look out for:
Working long hours but achieving less
More errors, missed details or difficulty concentrating
Irritability, cynicism or withdrawing from the team
Frequent short absences, lateness or illness
Comments about feeling exhausted, overwhelmed or unable to switch off
If you notice these signs, have a private, supportive conversation. Focus on what you have observed, ask how the person is doing and explain the support available. Our HR advice for managers can help with difficult conversations.
How an Employee Assistance Programme helps during busy season

Our EAP for accountancy firms includes:
24/7 confidential counselling and emotional support
Computerised CBT programmes for stress, anxiety and low mood
Legal and financial information
Wellbeing resources through the Wisdom app
A management support line for leaders handling difficult situations

Frequently asked questions
When is busy season for accountants?
For most UK practices, busy season runs from autumn through to the 31 January self-assessment deadline. Many firms have other peaks around company year-ends, VAT deadlines and, since April 2026, Making Tax Digital quarterly updates, with one due on 7 February.
What is the difference between stress and burnout?
Stress is usually short-term and linked to a specific pressure, such as a deadline. Burnout develops when stress continues for a long time without recovery, leaving people exhausted, detached from their work and less effective. Busy season can turn everyday stress into burnout if there is no chance to rest.
How many hours can accountants work during busy season?
Under the Working Time Regulations, average weekly working hours are limited to 48, usually averaged over 17 weeks, unless an employee chooses to opt out. Workers are also entitled to rest breaks and daily rest. Even where people have opted out, firms should monitor hours to protect wellbeing.
How should firms support staff after busy season?
Encourage people to take leave, avoid scheduling heavy work straight after the deadline and hold individual check-ins. A team review of what worked and what didn’t helps firms plan a better busy season next year.
