If you are a landlord in Pontypridd, whether you let property in the town centre, along the Taff Vale, in Treforest, Rhydyfelin, or further out towards Llantrisant Road, and your rental income from property exceeded £50,000 in the 2024/25 tax year, you are now operating under Making Tax Digital for Income Tax (MTD for IT). That means quarterly reporting to HMRC is no longer optional. It is a legal requirement.
The first quarterly deadline of 2026/27, covering the period 6 April to 5 July 2026, passed on 7 August 2026. If you submitted on time, well done. But the next critical milestone is fast approaching: the Q2 quarterly update, covering 6 July to 5 October 2026, must be submitted to HMRC by 7 November 2026. That deadline is closer than it might feel, and this guide from Belvoir Pontypridd is here to help you stay on the right side of it.
Understanding the four MTD quarterly deadlines for 2026/27
MTD for Income Tax replaces the traditional self-assessment tax return with a system of quarterly digital updates. For the 2026/27 tax year, there are four submission windows landlords in Phase 1 must be aware of:
- Q1 covers 6 April to 5 July 2026, with a submission deadline of 7 August 2026. This has already passed.
- Q2 covers 6 July to 5 October 2026, with a submission deadline of 7 November 2026. This is your immediate priority.
- Q3 covers 6 October to 5 January 2027, due by 7 February 2027.
- Q4 covers 6 January to 5 April 2027, due by 7 May 2027, followed by your End of Period Statement and Final Declaration.
Missing any of these deadlines triggers HMRC’s points-based penalty system. Each missed submission earns one penalty point, and once you accumulate four points, a £200 fine is automatically issued. Points can also be carried over, so staying on top of every deadline matters from the very start.
Are you in scope for MTD Phase 1?
Phase 1 of MTD for Income Tax applies to landlords and self-employed individuals whose qualifying income from property, self-employment, or a combination totalled £50,000 or more in the 2024/25 tax year. HMRC has been actively writing to affected landlords, and many will have received letters featuring a QR code directing them to register and set up compliant software.
Across Wales, an estimated 3,000 landlords fall within Phase 1 scope. If you own a portfolio of properties across Rhondda Cynon Taf, perhaps a mix of terraced homes in Cilfynydd, flats near Pontypridd town centre, or HMO accommodation close to the University of South Wales Treforest campus, and your combined rental income clears that threshold, you are required to comply now.
If you have not yet registered or received a letter, do not assume you are exempt. Check your 2024/25 figures carefully.
What digital records do you need to keep?
MTD for Income Tax requires landlords to maintain digital records of all rental income and allowable expenses throughout the tax year, not just at year-end. These records must be held in HMRC-compatible software and submitted directly through that software each quarter.
Income records
You must record all rental income received from your occupation contracts, the legally binding agreements between you and your contract holders under the Renting Homes (Wales) Act 2016. This includes standard occupation contract payments, any additional charges, and any other property-related income.
Expense records
Allowable expenses, including repairs and maintenance, letting agent fees, insurance, mortgage interest (subject to the current tax relief rules), and Land Transaction Tax costs where applicable, must also be recorded digitally and categorised correctly within your software.
Choosing compatible software
HMRC maintains an up-to-date list of MTD-compatible software providers on its website. Options range from full accounting platforms to simpler landlord-specific tools. The key requirement is that your software can submit quarterly updates directly to HMRC’s systems. A manual spreadsheet alone will not be sufficient unless it is bridged with a compliant submission tool.
Pontypridd’s rental market: the income context for MTD
It is worth pausing to consider the local market backdrop in which these obligations now apply. Average monthly rents across Rhondda Cynon Taf stand at approximately £748 per month as of May 2026, reflecting annual growth of around 2.5% year-on-year. Gross rental yields in the Pontypridd area sit at approximately 5.2% to 5.3%, making it a genuinely attractive market for landlords managing single lets, multi-property portfolios, and purpose-built rental accommodation alike.
For landlords whose portfolio income across areas like Treforest, Graig, Glyncoch, or Ynysybwl pushes past the £50,000 threshold, the MTD obligations are a direct consequence of that rental income, and managing compliance carefully protects the returns you have worked to build.
Planning ahead: MTD Phase 2 from April 2027
If your qualifying income currently sits between £30,000 and £50,000, you are not yet in scope, but Phase 2 of MTD for Income Tax begins in April 2027 and will bring that lower threshold into the mandatory regime. Landlords approaching the £30,000 mark should begin preparing their digital record-keeping systems now, rather than scrambling at the last minute.
Belvoir Pontypridd is already helping landlords across the area plan for Phase 2 eligibility, and early preparation makes the transition considerably smoother.
How Belvoir Pontypridd can support your compliance
One of the practical challenges MTD creates for landlords is the need for accurate, up-to-date financial records throughout the year. When you work with a fully managed lettings service, your rental income and key financial transactions are already being tracked and documented professionally, giving you a much stronger foundation for quarterly digital reporting.
Belvoir Pontypridd offers fully managed lettings services that take the day-to-day complexity of letting property off your plate. From occupation contract management under the Renting Homes (Wales) Act 2016 to rent collection, property inspections, and compliance support, our team understands the specific responsibilities that come with letting property in Wales.
Whether you own a single rental property in Pontypridd town centre or manage a portfolio spread across Rhondda Cynon Taf, having a professional agent in your corner makes meeting HMRC’s quarterly deadlines far more manageable.
What to do right now before 7 November 2026
With the Q2 deadline approaching, here is your immediate action checklist:
- Confirm that your digital records for the period 6 July to 5 October 2026 are complete and accurate within your MTD-compatible software.
- Ensure all rental income from your contract holders and all allowable expenses have been logged digitally for this period.
- Submit your Q2 quarterly update to HMRC through your compliant software before 7 November 2026.
- If you have not yet registered for MTD for Income Tax, contact HMRC or your accountant immediately. Late registration does not remove your obligation to submit.
- Begin preparing your records for Q3, which covers 6 October to 5 January 2027 and is due by 7 February 2027.
