Clear, accurate Self-Assessment support for individuals – filed correctly and on time
Not everyone who needs to submit a Self-Assessment tax return is running a business full-time. Many individuals are required to file because of additional income, director responsibilities, or changes in personal circumstances. The process can feel confusing, especially when you’re unsure what HMRC expects, what can be claimed, or when payments are due.
At Haupa Associates, we prepare and submit Self-Assessment tax returns for individuals with straightforward tax affairs. Our approach is simple: we keep the process clear, make sure everything is compliant, and explain your tax position in plain English, so you know exactly where you stand.
Who this service is for
This service is suitable for individuals who need to submit a Self-Assessment tax return, including:
- Company directors
- Individuals with additional income alongside employment
- Contractors working independently
- People with occasional self-employed income
- Anyone who has received a notice to file from HMRC
If you’re unsure whether you need to file, we can help you understand your obligations during a free review call.

Common reasons individuals need Self-Assessment
Individuals often need Self-Assessment due to:
- Director income (including dividends)
- Self-employed income alongside employment
- Side income that HMRC requires to be declared
- Situations where HMRC has issued a filing requirement
Even when finances are straightforward, the stress usually comes from uncertainty – not knowing what’s required, what documents are needed, or what you’ll owe.

Why it’s worth getting Self-Assessment done properly
A correctly prepared and on-time return helps you:
- Avoid late filing penalties and interest
- Reduce the risk of errors and future HMRC queries
- Understand your tax position clearly
- Ensure income is declared correctly
- Get peace of mind that everything is compliant
For most individuals, the real value is removing uncertainty and getting it done properly without stress.
Fixed-fee service with clear scope
We offer Self-Assessment as a standalone, fixed-fee service for simple returns.
- £200 per Self-Assessment tax return (simple cases)
- Charged 100% upfront before work begins
This is standard practice and ensures the work is completed efficiently and on time.
Simple returns typically include:
- Employment income
- Single-source self-employment income
- Straightforward director returns
If your situation is more complex (e.g., multiple income streams, property income, capital gains, foreign income), we’ll review and quote separately so scope and pricing remain fair.

What we need from you
To complete your Self-Assessment efficiently, we’ll typically ask for:
- Income information (e.g., P60s, summaries, invoices)
- Expense records (if applicable)
- Any relevant HMRC correspondence
- Confirmation of any changes in circumstances
Providing complete information early helps us file accurately and avoid delays.
When should you book?
Ideally, don’t leave Self-Assessment until the last minute. Booking early gives you:
- Time to gather information
- A clear view of what you owe
- More flexibility and less stress
If you’re close to a deadline or late, we may still be able to help – but late work is handled as priority and charged upfront.
