🤔 Still filing your tax return on paper? You’re not alone.
Plenty of people prefer paper, whether it’s familiarity, personal preference or simply habit. But paper comes with a much earlier deadline: 31st October 2026 for the 2025/26 tax year.
Here’s what many people don’t know:
👉 HMRC must receive your return by the deadline; posting it on the day isn’t enough
👉 The late filing penalty starts at £100, regardless of what you owe
👉 Penalties increase the longer your return is outstanding
At Advantax Accountants, we support individuals, landlords and the self-employed with accurate, stress-free Self Assessment. Whether you stick with paper or switch to online, we’ll make sure it’s done right.
