Your Quick-Start Guide to MTD for Income Tax: Do This Before the August 7th Deadline

01 Jun Your Quick-Start Guide to MTD for Income Tax: Do This Before the August 7th Deadline

If you feel like you’ve only just got your head around the last tax year, we’ve got some news: the rules of the game have officially changed. Making Tax Digital (MTD) for Income Tax is no longer a "coming soon" warning, it’s here.

For many sole traders and landlords across the UK, the first big milestone is fast approaching. August 7th, 2026, is the date when the very first mandatory quarterly update is due for those who joined the scheme in April.

At Harrison’s Accountancy, we know that "new HMRC rules" usually sounds like a headache. But honestly? With the right tools and a bit of prep, it’s actually a chance to get way more control over your business finances. As a Xero accountant firm with Platinum Champion status, we’ve seen first-hand how moving to digital can turn a stressful tax season into a quick, painless "check-and-click" job.

So, let’s break down exactly what you need to do to stay on the right side of the taxman before that August 7th deadline hits.

What is this August 7th deadline anyway?

Is this just another way of saying "pay your tax"?

Not quite. If you’re a sole trader or a landlord with a qualifying income of over £50,000, you officially entered the MTD for Income Tax Self-Assessment (ITSA) regime on April 6th, 2026.

Under the old rules, you’d wait until January the following year to tell HMRC what you earned. Under MTD, you have to send a Quarterly Update.

The first quarter of the 2026/27 tax year runs from 6th April to 5th July. The deadline to submit the data for that period is 7th August.

Think of it as a "digital check-in." You aren’t necessarily paying your tax bill on this date, but you are legally required to provide a summary of your income and expenses via MTD-compatible software.

Does this apply to you right now?

HMRC loves a threshold, so let’s see if you’re in the "August 7th club."

The current rollout of MTD for Income Tax is phased based on how much you earn. You need to follow these rules if:

• You are a sole trader or a landlord (or both).
• Your combined gross income is over £50,000. (This is based on your 2024/25 tax year figures).

If your income is between £30,000 and £50,000, you don’t have to join until April 2027. If it’s under £30,000, you’ve got even longer. But for the "£50k plus" crowd, the clock is ticking for that August submission.

If you’re unsure which bracket you fall into, especially if you have multiple streams of income like a consulting business and a rental property, it’s worth booking a call with us to double-check your status.

What exactly do you need to submit?

So, do I have to send every single receipt to HMRC?

Thankfully, no. HMRC doesn't want to see a photo of every coffee you bought for a client. What they want is a summary.

By August 7th, you must submit:

1. Total Income: All the money your business or property has brought in between April 6th and July 5th.
2. Total Expenses: A breakdown of what you’ve spent, categorised into the standard buckets HMRC uses (like "rent," "travel," or "cost of goods").

The catch? You must use software to do it. You can’t log into a government website and type the numbers in manually. The information has to flow directly from your records to HMRC via "digital links."

Why a Xero Accountant is your best friend right now

Can’t I just keep using my spreadsheet?

Well, technically you can use a spreadsheet, but it has to be "bridged" to HMRC with special software. Honestly? That’s doing things the hard way.

This is where being a Xero accountant makes our lives (and yours) so much easier. Xero is built for MTD. Because we are Platinum Champion partners, we know all the shortcuts to make this process seamless.

When you use Xero:

• Bank feeds do the heavy lifting: Your transactions flow automatically into the software. No more typing in bank statements.
• Categorisation is a breeze: Xero learns your patterns. It knows that "Shell" is probably travel and "Adobe" is a software expense.
• The August 7th submission is a few clicks: Once your transactions are reconciled, the software generates the summary and sends it straight to HMRC.

If you’re still working from a shoebox of receipts or a giant Excel file, now is the time to make the switch. It’s not just about compliance; it’s about seeing your profit in real-time. Check out our accountancy services to see how we can get you set up on the cloud.

Step-by-Step: Your MTD Quick-Start Checklist

Don’t leave it until August 6th! Here is how to prepare today.

1. Confirm your income: Look at your 2024/25 tax return. Was your total turnover (not profit, but total sales/rent) over £50,000? If yes, you're in.
2. Get the right software: If you aren't on Xero yet, let's talk. You need MTD-compatible software that "talks" to HMRC.
3. Clean up your records: Ensure your bookkeeping is up to date from April 6th onwards. Every transaction from that date needs to be recorded digitally.
4. Categorise as you go: Don't wait until July to categorise three months of spending. Spend 10 minutes a week in Xero clicking "OK" on your bank feed.
5. Sign up for MTD for ITSA: You usually need to sign up via the government gateway (or have your accountant do it for you).
6. Submit by August 7th: This is your first "Quarterly Update."

The "Media & Entertainment" Factor

If you’re a freelancer in the TV, film, or media industry, your accounts can be… well, complicated. Between varied contract types, weird expense rules, and specific VAT requirements, MTD can feel like a nightmare.

We specialise in the media and entertainment industry, so we understand the specific nuances of your "qualifying income." We don't just help you meet the deadline; we make sure you’re claiming every legitimate expense allowed in your field.

What happens if you miss the deadline?

HMRC has promised a bit of a "grace period" while everyone gets used to the new system. They are using a points-based system for late submissions. If you miss a quarterly update, you’ll get a point. Once you hit a certain threshold of points, you’ll get a financial penalty.

However, while they might be soft on points in Year One, they are still very keen on the data. Being "that person" who misses the very first deadline isn't the best way to start your relationship with the MTD regime.

Don't Panic, Just Plan

MTD for Income Tax is a big shift, but it’s manageable. If you’re a sole trader or landlord who is feeling a bit anxious about the August 7th deadline, remember: you don’t have to do this alone.
