Making Tax Digital for Income Tax has been in force since 6 April 2026 for those within scope — and if you are a landlord in Pontypridd, the question is no longer whether MTD applies to you, but whether you are fully set up to meet your new ongoing obligations.
For many buy-to-let landlords across Treforest, Rhydyfelin, and Hawthorn, the shift to digital record-keeping and quarterly reporting is unfamiliar territory. Whether you own a single student let near the University of South Wales campus in Treforest or a small portfolio of properties across the Rhondda Cynon Taf area, this guide is designed to walk you through exactly what you need to do right now to stay compliant.
What Making Tax Digital for Income Tax actually means for you
Making Tax Digital for Income Tax requires individuals with qualifying income above the relevant threshold to maintain digital records of their property and self-employment income and expenses, and to submit quarterly updates to HMRC through compatible software. Quarterly updates do not replace the annual tax return.
If your total qualifying income from property and self-employment was more than £50,000 in the 2024–25 tax year, you were required to comply from 6 April 2026. If your qualifying income is more than £30,000 in the 2025–26 tax year, your mandatory start date is 6 April 2027. A further threshold of more than £20,000 follows from 6 April 2028.
Even if your mandatory start date has not yet arrived, getting your systems in place now will save you significant stress later.
Why Pontypridd landlords need to act now
Pontypridd has one of the most active private rental markets in South Wales. The University of South Wales campus in Treforest continues to drive consistent demand for student accommodation, with contract holders filling properties along Coedpenmaen Road, Forest Road, and the surrounding streets year-round.
Rhydyfelin and Hawthorn attract working professionals and families seeking more affordable alternatives to Cardiff, with strong rental yields and low void periods making these areas popular with individual buy-to-let landlords.
Many of these landlords — particularly those managing one or two properties — have historically relied on spreadsheets or paper records to track their finances. MTD requires qualifying landlords to keep the required records digitally using compatible software. Spreadsheets may still be used where they form part of a compatible digital system.
Your August 2026 MTD compliance checklist
Confirm your income threshold and obligations
Start by reviewing your qualifying income for the 2024–25 tax year. This is your total gross income from self-employment and property before expenses and tax.
If your qualifying income was more than £50,000, you should already be using MTD for Income Tax and submitting quarterly updates. If you have not yet submitted your first update, take action now. HMRC will not apply penalty points for late quarterly updates during the 2026–27 tax year, but you must still submit the required updates before you can submit your tax return.
Choose HMRC-compatible software
You must use software that is compatible with MTD for Income Tax. Popular options suitable for individual landlords include:
Xero, QuickBooks, FreeAgent, and Hammock (designed specifically for landlords) are all widely used and offer varying price points. Many have free trials, and some accountants can provide access through their own licences.
When choosing your software, look for a platform that allows you to categorise rental income, log allowable expenses (such as maintenance, letting agent fees, and mortgage interest), and submit quarterly updates directly to HMRC.
Organise your records from 6 April 2026 onwards
Your digital records must cover the current tax year from 6 April 2026 if you use standard update periods. If you have been keeping paper or spreadsheet records since April, make sure the required information is transferred or digitally linked into your compatible MTD system.
The four quarterly submission deadlines for the 2026–27 tax year are 7 August 2026, 7 November 2026, 7 February 2027, and 7 May 2027. The first deadline has now passed, so landlords within scope who have not yet submitted their first quarterly update should take action now.
Understand your obligations under Welsh housing law
As a landlord operating in Wales, your responsibilities extend beyond tax compliance. Under the Renting Homes (Wales) Act 2016, your contract holders have specific rights regarding the standard of their accommodation, written occupation contracts, and notice periods.
Ensuring your properties are compliant with the Renting Homes (Wales) Act 2016 — including providing written occupation contracts and meeting fitness for human habitation standards — is part of your wider legal duty as a Welsh landlord. Belvoir Pontypridd can advise on how these obligations interact with your day-to-day property management.
Appoint or review your accountant
MTD for Income Tax is not simply a bookkeeping task — it changes how your tax affairs are managed throughout the year. If you do not currently work with an accountant, now is the right time to appoint one who is familiar with MTD requirements and with the Welsh rental market specifically.
An accountant can help you identify allowable expenses you may be missing, ensure your quarterly updates are accurate, and help you prepare and submit your tax return at the end of the tax year.
Common mistakes Pontypridd landlords are making right now
Common errors include failing to get compatible software ready, not keeping the required digital records, and mixing personal and rental income records in a way that makes reporting harder.
Another common issue is underestimating the volume of quarterly reporting. MTD requires four quarterly updates during the tax year, while the annual tax return remains in place. Building these dates into your calendar now will help prevent missed deadlines.

Take action after the first August quarterly deadline
The first MTD quarterly submission deadline of 7 August 2026 has now passed. Making Tax Digital for qualifying landlords in Pontypridd is no longer a future concern — it is a present obligation.

Review your income threshold, choose your software, get your records in order, and speak to a qualified accountant if you have not already done so. The earlier you act, the less disruptive the transition will be.
