Four Sole Traders, Two Quarterly Updates: What MTD Really Costs on a Tuesday Night

Making Tax Digital for Income Tax stopped being a slide in a webinar and became a Tuesday-night reality in April 2026. If you are a sole trader or a landlord with qualifying income over £50,000, you are in scope. The first quarterly update was due 7 August 2026. The second was due 7 November 2026 — yesterday, if you are reading this on publication day. Four owners agreed to talk me through what the first two quarters have actually felt like. Not the software demo. The receipts in the footwell.

Four owners, four very different Tuesday nights

Priya is a plumber in Leeds. Turnover just under £80,000. She files her own updates using an accounting app linked to a business bank account. Callum is a consultant in Bristol, turnover around £95,000, and he has an accountant who reviews everything. Elaine owns four rental flats in Norwich and still keeps agent statements in a ring binder. Dara runs a market stall in Birmingham — cash, card reader, and a carrier bag of supplier invoices that used to live under the counter.

All four are in the same regime. Their experiences are not the same.

The deadline is not the problem

The 7th of the month is a date. The actual problem is the 20 receipts in your jacket pocket, the builder's invoice in your email, and the three statements your letting agent sends as PDFs that you cannot search. The quarterly update itself takes 10 minutes. The tidying up before it takes two hours if you have left it since the last one.

Habit one: the weekly sweep

Priya spends 15 minutes every Friday going through her jacket, her van, and her email inbox. Photos of receipts go into a folder in her phone. Supplier invoices get forwarded to her accounting app. 'It is boring,' she said. 'But it is 15 minutes instead of three hours on the 6th.'

Callum does his on a Monday morning with a coffee. Dara does his on Sunday evening after the stall is packed away. The day does not matter. The rhythm does.

Habit two: one digital in-tray

All three of the copers have one place where every business document lands. For Priya it is an email alias — receipts at her business domain — that forwards to her app. For Callum it is a shared folder his accountant can see. For Dara it is a WhatsApp chat with himself, which sounds chaotic but works because it is one place instead of four.

Elaine's problem was not that she was disorganised. It was that she had five places: the ring binder, the agent portal, her personal email, the glovebox, and a shoebox in the spare room. The shoebox is dead. Five places is just a shoebox with better Wi-Fi.

Habit three: the pre-deadline accountant call

Callum books a 20-minute call with his accountant two weeks before each quarterly deadline. They look at the numbers, flag anything odd, and he files. Priya does the same with her bookkeeper, but only every other quarter. Elaine started doing it after January.

What it actually costs

Software is not the expensive bit. Most sole traders will pay £12 to £25 a month for an accounting app. The bigger line is the accountant. A straightforward sole trader might see a new monthly fee of £30 to £60 for quarterly reviews. A landlord with several properties can pay £80 to £120 a month, depending on how many agents and accounts are involved.

Then there is your own time. The owners who coped spent one to three hours a month on bookkeeping. The one who struggled spent a full weekend in October trying to reconstruct the summer.

The one who paid a penalty

Elaine is the only one of the four who has paid a penalty so far. It was not an MTD penalty. It was a £100 late-filing notice in January 2026 for her 2024-25 self assessment — the shoebox year. The notice landed in the same week her accountant asked for the first quarterly update. She describes it as 'the kick up the backside I needed, but an expensive one.'

She changed three things. She moved her rental income to a separate bank account. She asked her letting agent to send a monthly statement instead of a quarterly PDF. And she put a recurring 30-minute slot in her diary every second Tuesday. She has not missed a quarterly update since.

What to do if you are already behind

Do not buy more software. That is the trap. Open your bank feed, export the last three months of transactions, and book a call with your accountant or bookkeeper. Ask them what they need from you and by when. Then set a recurring calendar reminder for the 20th of the month after each quarter ends — not the 7th. The 7th is the deadline. The 20th is the deadline for getting your paperwork to someone else.

Making Tax Digital is not a software problem. It is a habit problem. The shoebox is dead. The replacement is not clever. It is a Friday sweep, one in-tray, and a short call before the deadline.
