Clear, accurate Self-Assessment support – without confusion or last-minute stress
Submitting a Self-Assessment tax return is a legal requirement for many individuals, but it’s also one of the most common sources of confusion and stress. Knowing what needs to be declared, what can be claimed, and when payments are due isn’t always straightforward – especially if tax isn’t something you deal with regularly.
At Haupa Associates, we prepare and submit Self-Assessment tax returns for individuals with straightforward tax affairs. Our aim is to make the process clear, compliant and predictable, so you understand your tax position and meet HMRC deadlines without unnecessary worry.
We focus on accuracy, clarity and calm communication – not rushing returns at the last minute.

Why getting Self-Assessment right matters
A correctly prepared Self-Assessment tax return helps you:
- Stay compliant with HMRC
- Avoid late filing penalties and interest
- Reduce the risk of errors and future HMRC queries
- Understand your tax position clearly
- Get peace of mind that everything is done properly
For most individuals, the biggest benefit is removing uncertainty and knowing the return has been handled correctly.
Simple vs more complex tax situations
Our fixed-fee Self-Assessment service is designed for simple returns, such as:
- Employment income
- Single-source self-employment
- Straightforward director income
If your tax affairs are more complex – for example involving property income, multiple income streams, capital gains, foreign income or crypto activity – we’ll review the scope first and confirm pricing before proceeding.
This keeps things fair and transparent for everyone.

Standalone service with clear payment terms
Self-Assessment tax returns are provided as a standalone, fixed-fee service.
- The fee for simple returns is £200 per tax return
- The service is charged 100% upfront before work begins
This approach ensures clarity of scope and allows the work to be completed efficiently and on time.
What we need from you
To prepare your Self-Assessment efficiently, we’ll typically need:
- Income information (P60s, summaries, invoices)
- Expense details where applicable
- Any relevant HMRC correspondence
- Confirmation of any changes in circumstances
Providing complete information early helps avoid delays and last-minute issues.
When should you book?
Ideally, Self-Assessment shouldn’t be left until the deadline.
Booking earlier allows:
- Time to gather information
- Clear understanding of what you owe
- Better planning for tax payments
If you’re close to a deadline or already late, we may still be able to help – though late work is treated as priority and charged upfront.
