Quick answer
Setting up as a sole trader involves registration with HMRC for tax, NICs, and potentially VAT. This checklist ensures your new client has all the foundational elements of their business structure, compliance, and accounting process in place from day one.
Why should you provide a formal setup service?
Helping a client get it right from the start establishes you as a trusted advisor, not just a year-end filler.
Many new sole traders struggle with the basics, like separating business from personal finance.
Guidance early on prevents common tax traps like failing to register for VAT when thresholds are breached.
What should you cover in the first meeting?
Registering for self assessment, discussing NICs, VAT threshold monitoring, and advising on bookkeeping are all essential early steps.
Essential setup tasks
- Register for self assessment
- Discuss voluntary vs mandatory VAT
- Advise on separating bank accounts

- Mixing business and personal money
- Failing to register for tax until the year end

Frequently asked questions
Is a sole trader simple?
It is legally simple but tax-wise, it requires disciplined record-keeping.
Does every sole trader need VAT?
No, only if turnover exceeds the registration threshold, but voluntary registration may be beneficial.
What about NIC?
Sole traders pay Class 2 and Class 4 NICs—check the current rates.
Can I incorporate later?
Yes, many sole traders start small and incorporate as the business grows.
How do I do bookkeeping?
Start with digital software; it's a foundation for MTD compliance.
What if they are a landlord too?
They still register as a sole trader for self assessment and declare the rental income on the same return.

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.
