Making Tax Digital

What is MTD ITSA?

MTD ITSA stands for Making Tax Digital for Income Tax Self Assessment. It is HMRC’s initiative to upgrade the traditional tax system with a digital-first approach. Instead of filing one large tax return at the end of the year, individuals and businesses will submit smaller, more regular updates through HMRC-approved software. This helps keep your financial records accurate and up to date while reducing the stress of year-end deadlines.

From April 2026, anyone earning more than £50,000 from self-employment or property rental will be required to follow MTD ITSA rules. This threshold drops to £30,000 in April 2027. The phased rollout is designed to allow taxpayers time to prepare and transition smoothly.

Key Terms: Digital Records, Quarterly Updates, and End-of-Period Statements

Let’s break down the essentials:

• Digital records are a mandatory requirement. You must record your income and expenses using software that is compatible with HMRC’s system. This ensures your records are consistently maintained, accurate, and accessible.
• Quarterly updates are summaries of your financial activity submitted every three months. These updates help HMRC keep track of your income and give you a clearer view of your tax obligations throughout the year.
• End-of-period statement (EOPS) is a final annual submission that confirms your total income and includes any necessary adjustments, allowances, or reliefs. This is where your actual tax bill is finalised.

Differences from Traditional Self Assessment

The traditional Self Assessment process allowed individuals to keep their records manually and submit a single tax return once a year. While convenient for some, it often led to rushed submissions, errors, and missed deductions.

MTD ITSA replaces this with a system that encourages ongoing record keeping and timely reporting through digital means.

How MTD for Income Tax Works

Digital Record Keeping Explained

Gone are the days of scribbling expenses on scraps of paper or trying to make sense of crumpled fuel receipts from six months ago. With Making Tax Digital, you need to maintain digital records of all business income and expenses using compatible software. These tools are designed to simplify your life, not complicate it.

The software automatically logs your entries, categorises your transactions, and helps you stay compliant with HMRC’s format. Whether it’s daily fuel, supply purchases, or that cheeky bacon roll for the crew meeting, every business transaction should be digitally recorded. Think of it like having a digital foreman who never takes a smoke break and always keeps the books tidy.

Submitting Quarterly Updates to HMRC

Instead of waiting until the year ends and dealing with a mountain of paperwork, you’ll submit a financial update to HMRC every quarter. These updates contain basic summaries of income and expenses for that period. No complex tax calculations required. Just totals from your digital records.

Once submitted, HMRC uses these summaries to give you an idea of what your potential tax bill might look like. This lets you budget more effectively and avoid surprise tax bills come January. You’re not paying tax quarterly, just reporting.

Quarterly deadlines will be:

• 5 August
• 5 November
• 5 February
• 5 May

Each update covers a three-month window, and the deadline falls one month after the period ends.

Finalising Your Tax Return

After you’ve submitted all four quarterly updates, it’s time to wrap things up with an End-of-Period Statement (EOPS). This is where your actual tax position is finalised. You can add any adjustments for allowable expenses, reliefs, or tax deductions that weren’t included in your quarterly updates.

Following that, you’ll complete a Final Declaration. This replaces the old Self Assessment return and confirms that all the information you’ve provided throughout the year is accurate. It’s like doing a final sweep of the job site before signing off with the client.

If you have multiple businesses or sources of income, you’ll need to submit separate EOPS for each. Your software will guide you through this process so you don’t need to stress over technicalities.

Key Deadlines and Rollout Timeline

MTD for VAT: Already in Effect

If you’re VAT-registered with a taxable turnover above £85,000, then you’re already in the Making Tax Digital club. Since April 2019, MTD for VAT has been mandatory. As of April 2022, even smaller VAT-registered businesses were brought into the fold.

The process is similar to MTD ITSA. You must keep digital records and submit VAT returns through HMRC-compatible software. This was the first step in HMRC’s digital transformation strategy, and it set the groundwork for the Income Tax rollout.

April 2026: Income Over £50,000

If you’re self-employed or a landlord with income over £50,000 per year, MTD ITSA will apply to you starting from April 2026. This includes gross income, so even if your profits are under £50,000, you’ll still be required to comply if your total earnings from self-employment and property go over that mark.

That means by the 2025-26 tax year, you should already have your software in place, digital records up to date, and be ready to submit your first quarterly update.

April 2027: Income Over £30,000

Those earning more than £30,000 but less than £50,000 from combined self-employment or property will be required to follow MTD rules starting in April 2027. This phase captures a significant portion of the UK’s sole traders and landlords, many of whom operate small but stable businesses.

It’s worth using the earlier timeframe to prepare. Get familiar with MTD-compatible software now so you’re not scrambling as the deadline approaches.

April 2028: Income Over £20,000 (Expected)

While not officially confirmed by HMRC at the time of writing, it’s widely anticipated that MTD ITSA will eventually extend to those earning over £20,000. This will bring a vast number of micro-businesses and part-time landlords into the system.

The earlier you prepare, the easier the transition will be. Don’t wait for the official letter to land before you act.

What Happens if You Miss a Deadline

Under MTD, compliance isn’t optional. Missing deadlines could trigger:

• Late submission penalties
• Interest on unpaid tax
• Points-based penalty system where repeated offences lead to fines

HMRC is implementing a more lenient system early on, giving some leeway as taxpayers get used to quarterly reporting. But don’t take that as a free pass. Staying ahead of the game means fewer headaches down the road.

Use the deadlines as motivators to clean up your bookkeeping, switch to digital tools, and get into the habit of regular updates.

Benefits of MTD for Taxpayers and Professionals

Save Time and Reduce Errors

For tradespeople and small business owners who’d rather be on-site than squinting at spreadsheets, MTD is a game-changer. Digital software automates much of the grunt work that used to eat up your evenings. Say goodbye to transposing numbers from one form to another or misplacing receipts when the van doubles as your filing cabinet.

Because the system pulls your data directly into HMRC’s format, there’s less chance of human error. This means fewer mistakes, fewer corrections, and fewer sleepless nights before tax deadlines.

Improve Accuracy and Compliance

MTD software does more than just digitise your records. It checks for discrepancies, flags missing data, and keeps everything compliant with current tax rules. Think of it as having a tax-savvy assistant who doesn’t take breaks and doesn’t forget to carry the one.

This accuracy builds trust with HMRC and protects you from unexpected tax bills or compliance checks. It also helps you understand your business better, giving insights that were previously buried in piles of paper.

Enhanced Data Security

Storing your tax records in the cloud might sound risky if you’re used to filing cabinets or USB sticks. But in reality, MTD-compatible software providers use bank-level encryption and secure data centres to protect your information.

If your laptop crashes or your phone takes a dive off the scaffold, your financial records are still safe and accessible. No more sweating over lost receipts or fried hard drives.

Easier Collaboration Between Clients and Accountants

If you work with an accountant or bookkeeper, MTD makes teamwork a breeze. You both use the same software platform, so your accountant can see your records in real time. This cuts down on back-and-forth emails, last-minute panics, and those awkward calls about mystery transactions.

Instead of hauling a box of papers into an office once a year, your accountant can offer support throughout the year, spotting tax-saving opportunities and giving proactive advice.

What MTD Means for You

If You’re a Sole Trader or Landlord

If you’re working for yourself or earning rental income, MTD might feel like one more hoop to jump through. But in reality, it gives you more control over your finances. You’ll track your income and expenses in real time, get fewer nasty surprises at tax time, and potentially spot ways to save money before it’s too late.

Instead of facing a once-a-year paperwork panic, you’ll handle bite-sized updates using software that simplifies the whole process. You can also set reminders for upcoming deadlines, monitor your cash flow, and access all your financial records from your phone or laptop.

For landlords with multiple properties, MTD helps keep your income streams separate and organised. No more second-guessing which expense belongs to which property.

If You Run a Small Business

For builders, mechanics, decorators, and mobile hairdressers, managing books often comes second to running the actual business. MTD shifts the heavy lifting onto software that handles receipts, invoices, and tax reporting in one go.

You’ll also be able to issue invoices straight from your phone, get paid faster, and even link your business bank account to your bookkeeping software. Less admin means more time to focus on your jobs and your customers.

And here’s a bonus. By maintaining cleaner records and submitting them regularly, you’ll look more professional to lenders, insurers, and potential business partners.

If You’re an Accountant or Bookkeeper

MTD makes your job easier and more efficient. Instead of being buried under year-end client emergencies, you can offer real-time services and keep everyone’s records clean and up to date.

You’ll work on shared software with your clients, access live data, and eliminate the frustrating paper chase. You can offer more strategic advice, identify risks early, and even grow your client base with scalable systems.

MTD also reduces the risk of errors and allows you to prepare reports, forecasts, and compliance checks with greater speed and confidence.

Case Studies: Real Businesses Using MTD

Danny, a Self-Employed Roofer from Leeds:
Before MTD, Danny handed his accountant a pile of receipts every January. Since switching to digital software, he logs expenses on-site and receives reminders when quarterly updates are due. “I used to dread tax season. Now, I don’t even think about it until the software pings me.”

Sandra, a Landlord in Birmingham:
Managing four assets used to be exciting. With MTD tools, Sandra links each asset to its own account. “I can see those things doing in seconds.”

Lund & Plumb’s Plumbing Business:
This team used to spend time rethinking their invoices and invoicing. Now they use an MTD app that tracks payments and pings their reminders. “We’ve reclaimed our time.”

How to Get Ready for MTD

Choosing the Right Software

The first step is choosing software that’s officially recognised by HMRC. Popular options like Sage, QuickBooks, Xero all offer features tailored for sole traders.

The right software should be:

• compatible with MTD for Income Tax.
• Allow for easy input of income and expenses.
• Offer features like invoicing, receipt capture, and bank integration.
• Include mobile access so you can manage things on the go.

If you’re not sure where to start, many software providers offer free trials or discounted plans for small businesses. Think of it like test-driving a new work van before committing.

Bridging Software vs Fully Compatible Solutions

Not all software is created equal. There are two main types to choose from:

• Bridging software: This acts as a digital bridge between your existing spreadsheets and HMRC’s system. It’s ideal if you already use Excel but want to stay compliant without changing your workflow too much.
• Fully compatible software: This is an all-in-one solution built specifically for MTD. It’s easier for most users and eliminates the risk of errors. These systems often come with extra features like invoicing tools and bank reconciliation.

If you’re comfortable with spreadsheets and just want a stopgap, bridging software works. But if you want a smoother ride with fewer headaches, go fully digital.

Registering for MTD with HMRC

To use MTD for Income Tax, you must register with HMRC before you start submitting updates. This isn’t automatic—you’ll need to sign up manually.

Here’s how:

• Visit the HMRC MTD ITSA registration page.
• Provide your Government Gateway ID and password.
• Enter your business information, including UTR and National Insurance number.
• Link your chosen software to your HMRC account.

Once registered, you’ll receive a confirmation email, and your software will be able to submit quarterly updates directly to HMRC.

Accountants and agents can also sign up clients through their own portals. If you’re not comfortable with the tech side, your accountant can handle registration and software setup for you.

Final Thoughts

Making Tax Digital might sound like just another bureaucratic hurdle at first, but it’s actually a smart, forward-thinking step that can make your financial life easier. Whether you’re a solo plasterer tracking expenses from your van or an accountant managing dozens of clients, MTD reduces stress, increases accuracy, and helps keep HMRC off your back.

The sooner you embrace digital tools, the sooner you’ll stop dreading tax time. The software does the heavy lifting so you can get back to doing what you do best—serving customers, growing your business, and getting paid.

Don’t wait until the deadlines are staring you in the face. Get ahead of the curve now, test a few tools, register early, and build confidence with each quarterly update.

Frequently Asked Questions (FAQs)

What is MTD compliance?

MTD compliance means keeping digital records and using HMRC-recognised software to submit quarterly updates and final declarations for your taxes. If you’re a sole trader, landlord, or small business earning over the threshold, this will soon be a legal requirement.

Do I need to register again for MTD ITSA if I already use MTD for VAT?

Yes, you do. MTD for VAT and MTD for Income Tax are separate schemes. Even if you’re already submitting VAT digitally, you’ll need to register again for MTD ITSA when it becomes mandatory based on your income.

Can I opt out of MTD?

Only in rare circumstances. You can apply for an exemption if you can’t use digital tools due to age, disability, or remote location with no internet access. Most people, however, will need to comply.

How can Sage help?

Sage is one of the leading MTD-compatible software providers. It helps users record income and expenses, generate invoices, automate bank feeds, and submit updates to HMRC with ease. It’s especially user-friendly for small businesses and tradespeople.
