Self Assessment tax returns in Norwich
If you’re a freelancer, self-employed, a company director, or you earn income that isn’t taxed at source, you’ll almost certainly need to file a Self Assessment tax return.
Plenty of people find out about this the hard way — usually via a letter from HMRC. If that’s you, or if you’re simply not sure where you stand, we can help. ATF Accountancy handles the whole process, from working out what you owe to filing on your behalf, and we look for every legitimate way to reduce your bill along the way.
What Self Assessment actually is
Self Assessment is how HMRC collects Income Tax on money it doesn’t already know about.
If you’re employed, your tax is deducted automatically through PAYE — your employer takes it from your salary before you see it, and sends it straight to HMRC. Nothing further required from you.
But if you earn money outside that system — profits from a business, rental income, dividends, gains from selling assets — HMRC has no visibility of it. A tax return is how you tell them.
Your return sets out what you earned during the tax year, where it came from, and what deductions or reliefs you’re entitled to claim.
The deadlines:
31 October — paper returns
31 January — online returns, and the date any tax owed must be paid
Do you need to file one?
You’ll need to submit a return if any of these apply:
You’re self-employed and earned more than £1,000 in the tax year
You’re a director of a limited company with untaxed income
You’re a partner in a partnership
You earn income from property
You earn over £100,000
You earn over £50,000 and claim Child Benefit
You have income from savings, dividends, or investments
You’ve sold assets during the year — a second property, shares, cryptocurrency
You want to claim certain tax reliefs
There are other circumstances that trigger a filing requirement, and the rules aren’t always obvious. If you’re unsure, ask us — a five-minute conversation is cheaper than a penalty.
Making Tax Digital: what’s changing for sole traders and landlords
Self Assessment as you know it is being replaced.
Under Making Tax Digital for Income Tax, sole traders and landlords above a certain income threshold will need to keep digital records and send quarterly updates to HMRC through compatible software, rather than filing one return a year.
It’s a significant shift in how you record and report income, and it’s being phased in by income level over several years.
We can tell you whether it applies to you and when, help you choose software that fits how you actually work, move your existing records across, and handle the quarterly submissions once you’re up and running. The aim is that the transition costs you a couple of conversations, not a stressful quarter.
Who we work with
Anyone who needs to file. Whether you’ve had a letter from HMRC, you’ve just gone self-employed, or you’ve been filing your own returns and would rather not anymore — we can help.
Every situation is different, so we start by looking at yours properly before recommending anything.
How we help
You’ll work with qualified accountants who do more than fill in boxes.
We prepare and file your return, but we also look at your wider position — what you’re paying, what you could legitimately be claiming, and how your decisions this year affect your bill next year. That context is usually where the value is.
We can also act as your agent with HMRC, which means we deal with them directly. Letters, queries, deadlines — all handled.
On penalties: missing the filing deadline triggers an automatic £100 fine, even if you owe no tax. Leave it longer and daily penalties start accruing, followed by further charges at six and twelve months. Late payment carries separate penalties and interest on top.
It’s an avoidable expense, and one of the more common reasons people call us in January.

Frequently Asked Questions
Who needs to file a Self Assessment tax return?
You usually need to file if you are self employed, a landlord with rental income, or you have other untaxed income such as dividends or foreign earnings. If you are unsure whether it applies to you, we can check in a few minutes.
What is the deadline for Self Assessment?
For online returns, the deadline to file and pay is 31 January following the end of the tax year on 5 April. If you need to register for Self Assessment for the first time, do that by 5 October after the tax year ends.
What happens if I file or pay late?
An immediate penalty applies for filing late, even if you owe no tax, and interest builds on tax paid late. The penalties increase the longer it is left, so it is worth acting early.
Can you handle the whole return for me?
Yes. We prepare and file the return for you, make sure you claim everything you are entitled to, and tell you exactly what to pay and when.
What is Making Tax Digital for Income Tax?
Making Tax Digital for Income Tax changes how self employed people and landlords report to HMRC. Instead of one annual return, you keep digital records and send quarterly updates using compatible software, followed by a final declaration after the tax year. It began in April 2026 for those with qualifying income over £50,000, extends to over £30,000 from April 2027, and to over £20,000 from April 2028. Qualifying income is your gross income from self employment and property, not your profit. We set up the software and handle the submissions so it runs smoothly.
