Making Tax Digital is changing how UK businesses report tax, and 2026 will bring more small and medium-sized enterprises under the MTD rules. For businesses in Aberdeen, that means reviewing how you keep records, submit returns, and plan for tax payments.
Some SMEs already use accounting software and digital tools, but many others still rely on spreadsheets or end-of-year handovers to their accountant. MTD sets clear rules around digital record-keeping and reporting frequency. These changes will affect many existing processes, and SMEs need to understand them to stay compliant.
Let’s explore what the MTD rules mean in practice and how you can prepare without disrupting your day-to-day operations.
Why Making Tax Digital Matters for Aberdeen SMEs in 2026
What Making Tax Digital is designed to achieve
HMRC introduced Making Tax Digital to move businesses away from paper records and manual returns. The aim is to increase accuracy by linking accounting systems directly to tax submissions and by encouraging more consistent record-keeping throughout the year.
For SMEs, tax reporting will become part of regular financial management rather than a single annual task. You will need to keep digital records that connect directly to HMRC through compatible software, and the figures you submit must come from those digital records rather than manual re-entry.
Key compliance dates businesses need to know
Making Tax Digital for VAT already applies to most VAT-registered businesses. If you fall into that category, you must keep digital records and submit VAT returns using compatible software.
From April 2026, MTD for Income Tax will apply to self-employed individuals and landlords whose qualifying income exceeds the relevant threshold. Further changes are scheduled for later years, which means more businesses will need to follow the digital reporting rules over time.
The risks of delaying preparation
If you leave preparation until the last minute, you might be forced to rush key decisions. For example, you might choose software without properly testing it, move data across in a hurry, or submit early returns with mistakes.
You might also end up pushing urgent work onto your accountant, which can disrupt your workflow and lead to additional fees.
Who Needs to Comply — and When
VAT-registered businesses
If your business is VAT registered, you should already be following the Making Tax Digital rules for VAT. That means you need to keep digital records and submit VAT returns through compatible software rather than entering figures manually on the HMRC portal.
If you still rely on spreadsheets, you must check that they link digitally to your submission process. Manual copying and pasting of figures isn’t good enough. If you haven’t reviewed your VAT process recently, now is a good time to confirm that it meets MTD standards.
Income Tax Self Assessment under MTD
From April 2026, Making Tax Digital for Income Tax will affect self-employed individuals and landlords whose qualifying income exceeds the HMRC threshold. Many SMEs operate through sole trader structures, so bear in mind that this change may apply directly to you – it’s not just for larger organisations.
Under MTD for Income Tax, you will send quarterly updates to HMRC based on digital records, followed by a final declaration at the end of the tax year. This changes how often you report and how regularly you need to keep your books up to date.
Directors and sole traders — what changes for you
If you run your business as a sole trader, MTD for Income Tax will affect how often you report income and expenses. Instead of reviewing figures once a year before filing your return, you will need to keep digital records throughout the year and submit quarterly updates.
For many SME owners, the distinction between business and personal reporting is not always clear. MTD makes that separation more important, especially when you draw dividends, take a salary, or hold personal property alongside your company.
Step 1: Audit Your Current Financial Processes
How you currently record income and expenses
Before you change anything, look at how you record income and expenses today. Do you enter transactions into accounting software as they happen, or do you update figures at the end of each month? Do you reconcile bank accounts regularly, or do you rely on end-of-year adjustments?
For many SMEs, finance processes have grown gradually as the business has expanded. Bear in mind that what worked when turnover was lower may not work under quarterly reporting.
Identifying manual or spreadsheet-based gaps
Once you review how you record transactions, look closely at where manual steps still exist. Do you copy figures from one system into another? Do you calculate totals outside your main accounting software and then re-enter them?
Manual handling increases the chance of error, especially when you submit figures more frequently. If you rely heavily on spreadsheets, check whether they link digitally to your tax submission process or whether someone still needs to move data across by hand.
Assessing digital readiness across your team
MTD doesn’t just affect software; it affects the people who use it. So, look at who records transactions, who reviews the figures, and who submits returns. For example, if only one person understands the bookkeeping system, that’s a risk. Check whether your team understands how transactions move through the system and how figures reach HMRC. If there are gaps, address them before the changes come into force.
Step 2: Move to Compatible Digital Record-Keeping
What qualifies as MTD-compatible software
Not all accounting software meets the Making Tax Digital rules. To comply, your system must keep digital records and link directly to HMRC for submission. It must also maintain a digital audit trail rather than relying on manual re-entry of totals.
If you currently use basic bookkeeping tools, check whether they connect directly to HMRC or whether you rely on a workaround. HMRC publishes a list of approved systems, which can help you confirm whether your current setup meets the standard.
The difference between bridging software and fully integrated systems
Some SMEs use bridging software to link existing spreadsheets to HMRC for submission. This can work if your underlying records meet the digital rules and the digital link stays intact from start to finish. However, a fully integrated accounting system records transactions, stores supporting data, and submits returns from the same platform. That means you do not need to move figures between systems, and you can see your tax position more clearly throughout the year.
How to choose a solution that fits your business size and sector
Start by thinking about how your business actually operates. For example, a small consultancy in Aberdeen will have different reporting needs from a construction firm or a retail business. Look at your transaction volumes, VAT complexity, and whether you will need project or job costing built into the system.
Then, consider how many people will use your Making Tax Digital software and what level of access each person will need. For example, if only one person handles the books, a straightforward system may work, but if several team members input data, you will need clearer controls and more defined permissions.
Finally, think about growth. If turnover increases or you hire additional staff, your reporting process should be able to cope and scale without forcing you to change systems again within a year.
Step 3: Prepare for Quarterly Reporting
What information must be submitted?
Under MTD for Income Tax, you will send HMRC a quarterly summary of your business income and allowable expenses. The figures must come directly from your digital records, not from totals you calculate separately.
That means you will need to record income and costs accurately throughout the year. If you code expenses to the wrong category, your quarterly update will reflect that mistake.
How quarterly submissions affect cash flow planning
Quarterly updates do not automatically mean quarterly tax payments, but they will give HMRC more regular visibility of your profits. That means you will also see your projected tax position more often.
If you review those figures properly, you can set money aside across the year rather than scrambling when a payment deadline approaches. For many SMEs in Aberdeen, that shift alone will change how you manage working capital, especially if your income is prone to fluctuating.
Building reporting into your internal finance calendar
It’s a good idea to add MTD reporting dates to your internal finance calendar now. If you don’t plan for your quarterly submission dates in advance, they are likely to compete with payroll runs, supplier payments, and other deadlines.
Common MTD Mistakes SMEs Should Avoid
Waiting until the last minute to transition
If you delay system changes until a deadline approaches, you may rush your software decision, move incomplete records across, and submit your first return without fully testing your process. If, on the other hand, you give yourself time to prepare, you can compare your options properly and train your staff before quarterly submissions begin.
Assuming your accountant will “handle it all”
If you assume that your accountant will take full responsibility for MTD compliance, you risk overlooking your own role in keeping accurate records. Your accountant can review and submit figures, but they rely on the data you provide. As such, it’s important to be clear about who records transactions, who checks them, and who signs off on each submission.
Underestimating staff training needs
If you introduce new Making Tax Digital software without properly training your team, you and your team could end up making costly mistakes. Remember, even small errors can carry forward into quarterly submissions. If several people input data, you need a shared understanding of categories, approval processes, and reporting deadlines.

A Practical MTD Action Plan for Aberdeen Businesses
Making Tax Digital will change how many SMEs record and report financial data. The shift is not complex in theory, but it does mean you need early planning and consistent execution.
Start by reviewing your current processes and looking at where people still move data by hand. Then check that your software meets HMRC’s digital link rules and that your team understands how figures flow through the system. Finally, add quarterly reporting dates to your internal calendar so that submissions become part of your regular finance routine rather than a last-minute task.
If you approach MTD in a structured way, you can meet the rules without disrupting your day-to-day operations or putting unnecessary strain on your team.
