MTD Countdown: Half of UK Small Businesses Unprepared for 7 August Deadline

The clock is ticking for small businesses and landlords across the UK. On 7 August 2026, the first mandatory quarterly update for Making Tax Digital (MTD) for Income Tax is due. Yet, recent reports suggest that nearly half of the UK's small business community is still caught in the "unprepared" camp.

If you are one of the thousands of sole traders or property owners feeling the pressure, you aren’t alone. At Accountant Search, we’ve seen a surge in inquiries from business owners looking for accountants for small business to help navigate this new digital landscape. While the shift to quarterly reporting is a significant change, it doesn't have to be a disaster.

In this post, we’ll break down exactly what you need to do before the 7 August deadline, explain the latest changes to the Capital Goods Scheme, and highlight the newly increased mileage rates that could put more money back in your pocket.

What Happens on 7 August 2026?

The 7 August deadline marks the end of the first "window" for submitting a quarterly digital update under the MTD for Income Tax rules. This update covers the period from 6 April 2026 to 5 July 2026 (the first quarter of the 2026/27 tax year).

If you are a sole trader or a landlord with a total qualifying income of more than £50,000, you are now legally required to:

1. Keep digital records of all your business transactions.

2. Use MTD-compatible software to send a summary of your income and expenses to HMRC every three months.

This is a major departure from the traditional once-a-year Self Assessment filing. Instead of one big tax "event" in January, you now have four smaller touchpoints throughout the year.

The "Soft Landing" – Why You Shouldn't Wait

The good news for those feeling behind is that HMRC has introduced a "soft landing" period for the 2026/27 tax year. There will be no financial penalties for late submissions of these quarterly updates during this first year.

However, don't let this leniency fool you into inaction. Submitting these updates is still a legal requirement. More importantly, these quarterly summaries are the building blocks for your final tax position. If you skip them now, you’ll face a massive digital backlog when it comes time to finalise your year-end return in January 2028: where full penalties will apply.

3 Actionable Steps to Take Today

If you haven’t started yet, here is your emergency "MTD Ready" checklist:

1. Verify Your Scope: Check your 2024/25 tax return. If your combined self-employment and property income was over £50,000, you are in scope. (Note: Those earning over £30,000 will join the scheme in April 2027).

2. Choose Your Software: You can no longer use spreadsheets alone or the old HMRC portal. You need software that talks directly to HMRC. Many business accountants in the UK recommend platforms like Xero, QuickBooks, or FreeAgent.

3. Link Your Bank Feed: The easiest way to keep digital records is to connect your business bank account to your software. This automates the data entry, meaning you only need to "categorise" transactions rather than type them in manually.

Beyond MTD: Two Other Big Changes You Need to Know

While MTD is taking the headlines, two other major tax updates have recently come into play that could impact your bottom line.

1. Capital Goods Scheme (CGS) Overhaul

As of 29 July 2026, the Capital Goods Scheme: which manages how VAT is recovered on large assets: has undergone a significant simplification.

• Computers are out: Computer equipment has been removed from the CGS entirely. This means you no longer have to track VAT adjustments on high-value IT kit over a five-year period.

• Property Threshold Increase: The threshold for land and buildings has jumped from £250,000 to £600,000. Only very large property projects will now fall under the complex CGS rules, significantly reducing the administrative burden for SMEs planning an office move or renovation.

2. Mileage Rates Hit 55p

In a move to support businesses facing high transport costs, the standard mileage rate for business travel has been increased to 55p per mile.

Crucially, this change is backdated to 6 April 2026. If you have been recording your business trips at the old 45p rate, you (or your accountant) should adjust your records now to claim the extra 10p per mile. This is a simple way to reduce your taxable profit and is especially beneficial for contractors and mobile small businesses.

How a Professional Accountant Can Help

Navigating MTD, CGS changes, and backdated mileage rates is a lot for any business owner to handle alone. This is where corporation tax accountants and SME specialists prove their value.

A good accountant doesn't just "do the books." They provide:

• Software Setup: Helping you choose and configure the right MTD-compatible tools so you don't waste time on data entry.

• Compliance Peace of Mind: Ensuring your quarterly updates are accurate so you don't trigger unnecessary HMRC enquiries.

• Tax Planning: Identifying opportunities, like the new mileage rates or CGS thresholds, to ensure you aren't overpaying.

Whether you are looking for accounting services for SMEs or need a comparison of the best UK accountants, getting professional advice is the best way to turn tax stress into business growth.
