If you’re self-employed or earn rental income anywhere in Royal Docks, Canary Wharf or the wider East London area, the way you report that income to HMRC has just changed — whether you’ve noticed yet or not. Making Tax Digital for Income Tax (MTD for ITSA) became mandatory from 6 April 2026, and it’s already reshaping how thousands of sole traders, freelancers and landlords across the capital keep their books.
This isn’t a future warning. It’s happening now. If your gross self-employment or property income was above £50,000 in the 2024/25 tax year, you should already be using MTD-compatible software instead of filing the traditional annual Self Assessment return. If you’re below that threshold, the rules will catch up with you in 2027 or 2028 — so it’s worth understanding now rather than scrambling later.
At Walden Way & Co, we’re chartered accountants in East London working with sole traders, contractors and landlords across Royal Docks, Canning Town, Canary Wharf and the wider Docklands area, and MTD has been one of the most common questions we’ve fielded this year. Here’s what it actually means for you.
What Is Making Tax Digital for Income Tax?
Making Tax Digital for Income Tax (often shortened to MTD for ITSA) replaces the old once-a-year Self Assessment tax return with a rolling cycle of digital record-keeping and quarterly updates sent directly to HMRC. Instead of gathering twelve months of receipts and invoices in January and hoping nothing’s gone missing, you keep digital records throughout the year and submit a summary roughly every three months, followed by a final declaration at year-end confirming your total income, expenses, reliefs and allowances.
It’s the income tax equivalent of Making Tax Digital for VAT, which has applied to most VAT-registered businesses since 2019. The principle is the same: HMRC wants real-time, software-based reporting rather than annual paper-style submissions.
Who Has to Comply, and When
MTD for ITSA is being phased in based on income, not business type:
- From 6 April 2026 — mandatory if your gross self-employment and/or property income was over £50,000 in the 2024/25 tax year
- From 6 April 2027 — mandatory if that gross income was over £30,000 in the 2025/26 tax year
- From 6 April 2028 — mandatory if that gross income was over £20,000 in the 2026/27 tax year
The detail that catches most people out is the word “gross.” HMRC looks at your turnover, not your profit. A self-employed graphic designer billing £55,000 a year but only taking home £38,000 after expenses is still over the £50,000 threshold and inside MTD from April 2026. The same applies to landlords — it’s rental income received, not net profit after mortgage interest and maintenance costs.
If you have both self-employment and rental income, HMRC adds the two together. A contractor earning £30,000 from consulting work and £25,000 from a buy-to-let in Custom House would have £55,000 of combined qualifying income — over the threshold, even though neither income stream alone would trigger it. You can check the current rules directly on GOV.UK’s Making Tax Digital eligibility guidance.
There’s genuine relief for many local business owners here too: limited companies are not affected. HMRC confirmed that Making Tax Digital for Corporation Tax is not proceeding, so if you trade through a limited company, your company’s tax return is unaffected by any of this — only personal income from self-employment or property counts.
What You’ll Actually Need to Do
Once you’re mandated into MTD for ITSA, the practical changes are:
- Choose MTD-compatible software — Xero, QuickBooks, FreeAgent and Sage are the most common — and authorise it to communicate with HMRC
- Keep digital records of business income and expenses as you go, rather than reconstructing them from paper receipts months later
- Submit a quarterly update roughly every three months, summarising income and expenses for that period
- Submit an End of Year Final Declaration, which performs the same function as the old Self Assessment return — confirming reliefs, allowances and your total tax position for the year
The quarterly updates are lighter-touch than a full tax return; they’re closer to a running total than a finished set of accounts, so you can correct figures before the final declaration without penalty. The bigger shift is behavioural: tax becomes something you manage continuously rather than something you deal with once a year in a January panic. The ICAS guide to Making Tax Digital is a useful technical reference if you want to work through the rules in more detail.
Once you’re mandated into MTD, you generally need to stay in it for at least three consecutive tax years, even if your income later drops back below the threshold.
What This Means If You’re Self-Employed or a Landlord Around Royal Docks or Canary Wharf
East London has changed a great deal over the past decade, and the people affected by MTD for ITSA reflect that. We see it across our own client base: events and exhibition contractors working the ExCeL London calendar, self-employed consultants servicing the financial and professional firms in Canary Wharf, tradespeople and freelancers based around Canning Town and Custom House, and a growing number of landlords letting out new-build flats in the regenerated areas around Royal Wharf and Silvertown.
Many of these clients are exactly the profile MTD is designed to capture — gross income comfortably over £50,000, but without an in-house finance team or existing digital bookkeeping habits. If that sounds like you, the sensible move is to get your software set up and your records digitised well before you’re forced into it by an HMRC letter.
Common Mistakes to Avoid
A few patterns come up again and again when self-employed individuals and landlords first move to MTD:
- Confusing turnover with profit when checking the threshold, and wrongly assuming they’re exempt
- Leaving software set-up until the deadline for their first quarterly update is already looming
- Mixing personal and business transactions in the same bank account, which makes digital record-keeping far harder than it needs to be
- Assuming MTD applies to limited companies, when in fact it’s a personal income tax measure only
Penalties for MTD for ITSA now run on a points-based system rather than an automatic fine for every late submission, but repeated lateness still adds up to financial penalties — it’s worth getting the habit right from the first quarter rather than treating it as optional.
How Walden Way & Co Can Help
If you’re a sole trader, contractor or landlord anywhere in Royal Docks, Canary Wharf, Stratford or the wider Docklands area and you’re not sure whether MTD for ITSA applies to you yet, that’s exactly the kind of question our personal tax return service is built to answer. We can check your qualifying income against the thresholds, get your digital records set up correctly the first time through our bookkeeping services, and handle your quarterly submissions and final declaration so you’re not learning new software while also running your business.

Frequently Asked Questions
Do I need to use Making Tax Digital if I’m self-employed? Only if your gross self-employment and/or property income exceeds the relevant threshold for your tax year — £50,000 from April 2026, £30,000 from April 2027, or £20,000 from April 2028. Below those thresholds, you can continue filing a standard Self Assessment return for now.
What counts as qualifying income for MTD for ITSA? Qualifying income is your gross, before-expenses income from self-employment and UK property, combined. It doesn’t include PAYE salary, dividends, savings interest, pension income or your share of partnership profits.
Does Making Tax Digital affect limited companies? No. HMRC has confirmed that Making Tax Digital for Corporation Tax is not proceeding, so limited company tax returns are unaffected. MTD for ITSA only applies to personal income from self-employment and property.
What happens if I don’t comply with MTD for Income Tax once I’m mandated? You’ll be required to use compatible software rather than the standard HMRC online portal, and late or missing quarterly updates are tracked under a points-based penalty system, which can lead to financial penalties if submissions are repeatedly late.
Can an accountant handle the switch to Making Tax Digital for me? Yes. An accountant can check whether you’re affected, set up MTD-compatible software correctly, and manage your quarterly updates and final declaration on your behalf, so the transition doesn’t fall entirely on you.
