Further phases will follow from 2027 and beyond, steadily bringing more UK taxpayers into the regime.
Alongside this, frozen tax thresholds, new penalty systems and an ongoing shift to digital bookkeeping UK wide are reshaping how small and medium sized businesses manage tax and accounting. Doing nothing until 2026 is no longer a neutral choice. It risks higher admin costs, more stress and a greater chance of penalties and poor decisions.
This guide from bes accountancy, a London based accounting company serving clients across the UK, explains the key 2026 tax changes UK business owners need to know, who is affected, and how to turn compliance into a long term advantage.

Key Tax And Compliance Changes By 2026
Making Tax Digital for Income Tax
MTD for Income Tax 2026 will apply first to sole traders and landlords with qualifying income over fifty thousand pounds, based on the 2024 to 2025 tax year. From April 2027 it will extend to those with qualifying income over thirty thousand pounds, with further plans to bring in those over twenty thousand pounds in later years.
If you fall into scope you will need to
keep digital records in compatible software
send quarterly digital updates to HMRC
submit an end of period statement and a final declaration each year, instead of a single annual tax return.
This is a major mindset shift. Quarterly becomes the new normal for self employed people and landlords, and the quality of your digital bookkeeping will directly affect your tax estimates.
Frozen thresholds and fiscal drag
Personal allowances and higher rate thresholds have been frozen for several years. In real terms, that means more business owners and directors drift into higher rates of tax without earning more after inflation. Over the next few years this fiscal drag will quietly increase the number of people inside Self Assessment and within scope of 2026 tax changes UK.
The push towards digital bookkeeping
Banks, software providers and HMRC are converging on real time, digital data. Open Banking feeds, cloud platforms like Xero and QuickBooks, and electronic invoicing are becoming standard small business accounting trends 2026 rather than optional extras.
To help you see the landscape, here is a simple overview you can adapt into your own planning.
Change or trend | Who it affects most | From when | What must change |
MTD for Income Tax 2026 | Sole traders and landlords over fifty thousand pounds income | Six April 2026 | Move to compatible software, send quarterly updates, submit digital year end statements |
MTD for Income Tax 2027 | Those over thirty thousand pounds income | Six April 2027 | Same as above, with extra groups entering scope |
Ongoing fiscal drag | Company directors, landlords, higher earning staff | Already happening | More people file Self Assessment, more need for planning and cash flow forecasts |
Shift to digital bookkeeping | Almost all SMEs | Now and accelerating | Replace manual spreadsheets with cloud systems, live bank feeds, digital receipt capture |
The Hidden Costs For Self Employed People, Landlords And Small Companies
Self employed people and landlords
If you run a professional services practice, creative studio, online shop or property portfolio, the new rules will change how you work with your accountant. Missing quarterly updates can trigger penalty points and eventually fines under the new points based late submission regime.
Poor quality digital data can also hurt you even if you file on time. Mis coded transactions or incomplete records can create misleading profit and tax estimates through the year.
That can lead to:
surprise tax bills at the final declaration
over payments that damage cash flow
higher fees to fix records under time pressure
Landlords with multiple properties face extra risk. Mixed income from rent and self employment may push them into MTD for Income Tax 2026 earlier than expected if total qualifying income crosses the threshold.
Limited companies and employers
Even if your limited company is not directly in MTD for Income Tax, the wider digital shift still matters.
You will need:
robust digital records to back up Companies House filings and corporation tax returns
clean links between company accounts, director Self Assessment and payroll
systems that can provide lenders and investors with timely, accurate numbers
Weak records close off funding options and slow growth. Strong, real time data makes it easier to secure finance, negotiate with suppliers and plan investment.
As Besnik Vata, director of bes accountancy, a London based accounting company, puts it, “The real cost of ignoring 2026 is not just penalties. It is years of decisions made on guesswork rather than live numbers.”

The Hidden Costs Of Staying Offline And Spreadsheet Based
Some owners hope they can keep using spreadsheets and paper, then ask an accountant to convert everything once a year. By 2026 that approach will become both risky and expensive.
Paper and spreadsheet records increase the risk of error and missing information. They make HMRC enquiries harder to defend, because you may not be able to show clear audit trails and digital evidence on request. Even when you outsource bookkeeping, directors remain responsible for the accuracy of records and submissions.
Decision making also suffers. Without cloud dashboards showing cash, debtors, creditors and tax forecasts you are always looking in the rear view mirror. That makes it harder to:
spot margin erosion early
adjust prices when costs move
plan dividends, drawings and tax payments with confidence
If you ever want to sell your business or bring in investors, poor historic data can directly reduce your valuation. Buyers will discount for uncertainty and build in extra caution if the numbers are patchy or hard to verify.
This is why bes accountancy already uses Xero and QuickBooks to give London and UK clients real time visibility, not just end of year reports. You can see an example of how we embrace modern tools in our Instagram post on Xero for small and medium sized businesses.

Minimal Compliance Versus Proactive Planning
To bring this to life, imagine two different approaches to Making Tax Digital 2026.
Scenario A, bare minimum, last minute compliance
A business waits until early 2026, then rushes to pick software from a list. The team is trained under pressure, historic data is imported imperfectly, and the first quarterly update is treated as a test. Mistakes slip through, staff are confused and the owner has to pay both for software and for emergency fixes. Penalty points become a real risk.
Scenario B, proactive cloud adoption with bes accountancy
In 2025 the same size business books a 2026 readiness review with bes accountancy.
Together we:
review current records and tax position
select the right digital bookkeeping UK solution, such as Xero or QuickBooks
migrate data and set up bank feeds and digital receipt capture
build quarterly habits before they become mandatory
Over three to five years the difference is clear. The proactive business pays modest software and support fees, but avoids penalties, saves admin time, and gains better cash flow from real time reporting. The last minute business spends more on rushed support, operates in constant uncertainty and may still face fines.

Frequently asked questions, 2026 tax and accounting changes
1. Who will MTD for Income Tax 2026 affect first?
From six April 2026 MTD for Income Tax will apply to sole traders and landlords with qualifying income over fifty thousand pounds, based on the 2024 to 2025 tax year. Those with income over thirty thousand pounds are due to follow from April 2027, with further phases planned. If you are close to these levels now it is sensible to prepare.
2. Will MTD for Income Tax 2026 mean more admin for my business?
If you stay on spreadsheets and paper, yes. You will need to keep digital records and send quarterly updates, which can feel like extra work if you are doing everything manually. If you adopt cloud software with bank feeds and receipt capture, much of the data entry happens automatically and quarterly becomes a light review rather than a full rebuild.
3. What software will I need to comply with MTD for Income Tax 2026?
You will need compatible software that can keep digital records and send quarterly updates to HMRC. Xero and QuickBooks are two leading options that bes accountancy uses for small and medium sized businesses across London and the UK. We help you choose the right platform, set it up and train your team so it becomes a daily tool, not a yearly chore.
4. When should I start preparing for UK 2026 tax changes?
In our view the best time is during 2025 accounts and tax work. That gives you at least a full year to migrate, clean data and build quarterly habits. Leaving everything to early 2026 compresses training, migration and your first MTD submissions into a short, stressful window.
5. How can bes accountancy support my transition to digital bookkeeping UK?
