But that’s not enough, is it. So, let us walk you section by section through the letter, explain what it really means and give you practical steps to ensure you stay compliant without stress or confusion.

What Is HMRC’s MTD Letter?
HMRC letters can feel intimidating. The language is formal, confusing and full of dates and deadlines. Let’s take it apart and make it easy to understand.
Exact Wording from the HMRC Letter:
You will need to change the way you report your income and expenses to HMRC.
You'll need to use Making Tax Digital for Income Tax from 6 April 2026 as your total
income was over £50,000 from self-employment and property in your 2024 to 2025
tax return. This is your qualifying income which is worked out before expenses or taxes are
deducted.
What This Means?
HMRC is telling you that the way you report your income and expenses is changing. From 6 April 2026, you can no longer submit your tax returns through the current HMRC Self Assessment online portal or on paper. You’ll also not be reporting your taxes just once a year, as you’ll be within the scope of Making Tax Digital for Income Tax (MTD ITSA), not the traditional Self Assessment Tax Return process. Further, you will need to use HMRC-recognised software like RentalBux to submit your tax returns.
We’ll expand more on all this in later sections but what you need to understand right now is that you received this letter because your total income from property and/or self-employment in the 2024–2025 tax year was above £50,000. That figure, which HMRC calls your ‘qualifying income,’ is calculated before you deduct any expenses or tax allowances.
Key Point: |

This is not a tax demand. You are not being told you owe money. This is a notice that the way you submit your tax information is changing. There is nothing to panic about, but you do need to take some actions before 6 April 2026. These actions are:

What Is Making Tax Digital (MTD) for Income Tax?
Making Tax Digital for Income Tax, or MTD for ITSA, is the UK government’s ambitious plan to modernise how landlords and sole traders report their income and expenses to HMRC. Think of it as moving from annual catch-up accounting to real-time, organised financial reporting by keeping everything digital, up-to-date and in the hands of HMRC before your tax return is even due.
If you’re a landlord used to filing once a year, this represents a big shift. But don’t worry, it’s manageable with the right tools and preparation.
Under the Current System | Under MTD for Income Tax from 6 April 2026 |
|---|---|
You submit one Self Assessment Tax Return per year (by 31 January) | You must use HMRC-recognised software |
You can submit your return either via the HMRC online portal or on paper forms | You must keep digital records of your income and expenses |
You can file all your records at once at the end of the year | You must send four quarterly updates to HMRC each year |
| Despite quarterly updates, a Final Declaration is still required by 31 January following the end of the tax year |
Exact Wording from the HMRC Letter:
Making Tax Digital for Income Tax is a new way for sole traders and landlords to
report income and expenses to HMRC. You, or your agent if you have one, will need
to use software that works with Making Tax Digital for Income Tax to:
create, store and correct digital records of your self-employment and property
income and expenses
send your quarterly updates to HMRC
submit your tax return by 31 January the following year.
What Is ‘Qualifying Income’ for MTD?
This is one of the most common points of confusion. Your qualifying income is not your profit. It is your total gross income from property and/or self-employment before any deductions.
What Counts as Qualifying Income | What Does Not Count as Qualifying Income |
|---|---|
Rental income from Buy-to-Let properties | Your PAYE salary or employment income |
Rental income from holiday lets | Pension income |
Income from Airbnb or short-term lets | Dividend income |
Income from self-employment (sole trader) | Savings interest |
Income from furnished holiday lettings | Capital gains from property sales |
Lets Learn With Example
If you earn £42,000 in rental income and £12,000 as a self-employed contractor, your qualifying income is £54,000, which is above the £50,000 threshold, even if your taxable profit after expenses is much lower.
What Are Quarterly Updates?
Under Making Tax Digital for Income Tax, landlords must submit four quarterly updates each tax year. These updates give HMRC a running view of your income and expenses.
Each quarterly update is a summary of your income and expenses, and it works like this:
Cumulative Reporting - Each update includes income and expenses for the current quarter plus all previous quarters in the tax year. This ensures HMRC sees your total financial picture as the year progresses.
Not a Tax Payment - You do not pay tax every quarter. The updates are just a way to track and report figures before submitting your Final Declaration.
Final Tax Return Still Required – You must submit a Final Declaration, analogous to the present Self Assessment Tax Return by 31 January following the end of the tax year.
Even “Nil” Quarters Count - If a quarter has no income or expenses, you still submit a “nil” update. This keeps your reporting up-to-date and avoids penalties for missing a quarter.
Quarterly Update Deadlines
What You Need to Know About the Penalty System?
HMRC has put in place a new penalty regime for missing quarterly updates and missing payments, as suggested by the letter.
Exact Wording from the HMRC Letter:
Under the new late submission penalties, a penalty point is awarded where a quarterly
update or tax return deadline is missed. Once a four-point threshold is reached, a
financial penalty will be issued.
There are also new penalties for late payment of tax from the 2026 to 2027 tax year which are more proportionate to how long it takes you to pay what you owe..
Late Submission Penalties
Each time you miss a quarterly update deadline or your final tax return (Final Declaration) deadline, you receive one penalty point
Once you accumulate four penalty points, HMRC issues a financial penalty
Keep filing on time for a while, and the points reset, so one slip-up isn’t the end of the world if you get back on track
Important for 2026–2027 (the First Year):
You will not receive a penalty point even if a quarterly update is submitted late during the first year (2026-2027 tax year) of MTD implementation. However, you must still submit all quarterly updates before you can submit your final tax return.

From the 2027–2028 tax year onwards, late quarterly updates will attract penalty points.
Late Payment Penalties
In addition to submission penalties, there are new late payment penalties that you need to be aware of. These are proportionate to how long you take to pay what you owe.
Days Late | Penalty |
|---|---|
0 to 15 | No automatic penalty (interest still applies) |
16 to 30 | 2% of the outstanding tax |
31+ | 4% of the outstanding tax, plus daily charges after 31 days |
Note: Filing updates on time doesn’t mean you avoid payment penalties; paying late will still get you fined. | |
Don’t Confuse the Two:
|
Do I Need to File My Self Assessment Tax Return If I’m Eligible for MTD?
Exact Wording from the HMRC Letter:
You should still submit your tax return for the 2025 to 2026 tax year as normal. Financial penalties will be applied where a tax return or payment is made after
the due date.
Nothing changes for your 2025–2026 Self Assessment Tax Return. Submit it as you normally would by 31 January 2027. MTD only changes things from the 2026–2027 tax year onwards.
Making Tax Digital Exemptions
The HMRC letter mentions exemptions but does not go into much detail.
But, worry not, here is a clear breakdown of who may be exempt from Making Tax Digital.
Digitally Excluded
If HMRC has already confirmed you are digitally excluded (meaning you cannot use digital tools due to age, disability, location or religious beliefs), you do not need to comply with MTD requirements.
As the letter states:
If we've already confirmed that you're digitally excluded for Making Tax Digital
for Income Tax, please ignore this letter.
If you believe you qualify for digital exclusion but have not yet applied, you can apply to HMRC for an exemption. Approval may be permanent or reviewed periodically, depending on your circumstances.
Aside from digital exclusion, HMRC notes a few other scenarios where MTD might not apply immediately or at all.
Your qualifying income drops below the stated MTD thresholds (£50,000 for 2026, £30,000 for 2027 and £20,000 for 2028) in later tax years
You are in the final year of your self-employment or letting business
If, on 31 January before a tax year starts, you do not have a National Insurance number, you are automatically exempt from MTD for Income Tax for that year
Some trustees, personal representatives or other specific circumstances can also qualify for MTD exemptions

Step 2: Sign up for MTD for Income Tax
Selecting the right software is only the first step. You also need to formally register for MTD for Income Tax through HMRC. You can do this via GOV.UK. After registering, you’ll also need to authorise your software, i.e., RentalBux, to access the your HMRC account for the purpose of submitting MTD-compliant updates on your behalf.

Here’s what to do:
Keep your income and expense records accurate and up-to-date
Log all allowable expenses; repairs, insurance, mortgage interest, agent fees, everything counts
Keep digital copies of all receipts and invoices; snap photos, scan documents or upload PDFs into your software
The more organised your records, the smoother your MTD experience will be and the less likely you are to make mistakes that could trigger penalties.
