It’s April 1st. Usually, this is the day you cautiously check your chair for whoopee cushions or brace yourself for a “we’re moving the office to Mars” company announcement. But in the world of tax, April Fools’ Day isn’t just a 24-hour event; it’s a year-round season of misconceptions.
At E R Grove and Co, we’ve heard some absolute crackers over the years. To keep you from being the punchline of a very expensive joke, we’ve busted the top tax myths currently doing the rounds in 2026.
Making Tax Digital (MTD) means I’m filing four tax returns a year.
This is the big one for 2026. With MTD for Income Tax officially live for those earning over £50,000, many are panicking that they now have four times the paperwork. Don’t worry: you aren’t doing four full Self-Assessments. Think of the quarterly updates as a “quick check-in” rather than a deep dive. It’s more like sending a text to HMRC saying, “Here’s where I’m at,” rather than writing them an essay every three months. It’s designed to give you a clearer picture of your cash flow, not to ruin your weekends.
If I didn’t get a letter from HMRC, I don’t owe anything.
HMRC isn’t like that one friend who forgets you owe them £20 for pizza. Just because they haven’t sent a formal nudge doesn’t mean you’re off the hook. In the UK, the “Self” in Self-Assessment is there for a reason; it’s your responsibility to tell them if you’ve started a side hustle, rented out a room, or sold some particularly profitable crypto. Waiting for a letter is like waiting for a personal invitation to pay your train fare; the inspector is still going to fine you when they show up.
I can claim my entire house as an office because I occasionally check emails on the sofa.
We love the enthusiasm, but unless your sofa is used exclusively for business (which is highly unlikely), HMRC is going to say “no.” You can claim a proportion of your bills based on the area of your home used for work, but trying to claim the heated swimming pool you’ve always wanted because you “think best while treading water” is a one-way ticket to an audit.
Cash is invisible to the taxman.
In 2026, very little is truly invisible. HMRC’s “Connect” AI system is smarter than ever, cross-referencing everything from bank accounts to social media. If you’re posting photos of a brand-new Ferrari but reporting an income that suggests you live on 12p noodles, the algorithm is going to have questions.
My accountant will find a magic loophole to make my tax bill £0.
We’re good, but we’re not wizards. Our job at E R Grove and Co is to ensure you pay the right amount of tax; not a penny more, but certainly not a penny less than the law requires. Real tax planning is about smart, legal strategies (like pension contributions and ISA allowances), not “magic” tricks that end in a “please explain this” meeting with an inspector.
