Those with qualifying income over £50,000 must report digitally from April 2026, with those over £30,000 following in April 2027. This requires keeping digital records and sending quarterly updates using MTD-compatible software.

FAQ's

Do I need an accountant to do my tax return?

While not mandatory, hiring an accountant for your tax return can ensure accuracy, identify potential deductions, and navigate complex tax regulations, ultimately saving time and minimising errors.

Can I claim accountant fees on tax return?

Yes, accountant fees are generally tax-deductible. You can include them as a business expense on your tax return, potentially reducing your taxable income and lowering your overall tax liability.

Is it mandatory to file self-assessment in the UK?

You need to file if you had untaxed income, are self-employed, a landlord, a company director, or earned over £100,000. HMRC requires a return if your income isn’t taxed automatically through PAYE. That includes things like side gigs, dividends, crypto gains, or rental income. Even if you're not sure, it’s safer to check than to ignore it — HMRC fines for missing it aren't cheap.

What documents do I need for my tax return in the UK?

You’ll need proof of income, expenses, and any tax already paid. Bank statements, P60s, P45s, invoices, and pension summaries are common. If it shows money coming in or going out, it probably matters. The more accurate your records, the better we can file — and the lower your tax bill might be.

What happens I missed the deadline?

If you missed the 31 January deadline, HMRC will charge late penalties. But you can still file now to stop the fines from getting worse. They start at £100 and stack up fast. You’ve got 3 months before daily fines kick in. The sooner you act, the more you save. We’ll help you get it sorted.

How safe is your services at DASA Accountancy?

Yes — all your data is encrypted, stored safely, and only handled by qualified accountants. We use trusted tax software with bank-grade security. No shared logins. No outsourced handling. It stays between you and your assigned accountant. Your tax info stays locked up tighter than a drum.

Can you help if I’ve never filed a tax return before?

Yes — we work with first-time filers all the time and keep the process dead simple. You don’t need to know the forms or codes. We’ll ask you plain questions, explain what we need, and handle the rest. You’ll know what’s due and when — no guesswork.

What’s the deadline for self assessment returns?

The deadline to submit online is 31 January every year. Paper returns are due by 31 October. If you register late, the deadline still applies. And if you owe tax, it’s due the same day. HMRC doesn’t give reminders — but we do. We’ll keep you one step ahead.

What if I made a mistake on a previous return?

Mistakes can be corrected with an amended return — and we can help you fix it. HMRC lets you make changes for up to 12 months after the deadline. If you overpaid or underreported, we’ll sort it out. No panic, no long calls with HMRC.

Can I claim expenses?

Yes — if you’re self-employed or a landlord, you can claim allowable expenses to reduce your tax bill. This includes things like mileage, home office use, tools, subscriptions, and more. We’ll review your records and make sure you claim everything you’re entitled to — without crossing any lines.

Can you handle late or backdated returns?

Yes — we help clients catch up on late returns, whether you’re one year behind or several. You don’t need to go it alone. We’ll help you clean it all up, reduce penalties where possible, and deal with HMRC on your behalf. The sooner we file, the better.

What if I already paid tax through PAYE?

You might still need to file a return if you had other income — even if your main job used PAYE. This includes freelance work, crypto, dividends, or rental income. HMRC wants the full picture. If you earned extra and didn’t report it, you could still face fines later.
