LET PROPERTY CAMPAIGN AND DISCLOSURE
How the Let Property Campaign Helps Landlords Put Things Right
If you've let out a property and not declared all the rental income to HMRC, you are far from alone — and the good news is there's a recognised, relatively gentle way to put it right. As a specialist Let Property Campaign accountant, Pro Tax Accountant helps landlords across the UK make a clean, accurate disclosure with the lowest possible penalties. The Let Property Campaign is HMRC's long-running voluntary disclosure facility, open since 2013 and still active in 2026 with no announced end date. It's designed specifically for individual residential landlords, whether you have a single buy-to-let, a portfolio, a holiday let, a room let above the Rent a Room threshold, a property abroad, or income from an "accidental" letting after moving in with a partner.
(It doesn't cover companies, trusts or commercial property, which need different routes.) The process runs in three stages: you notify HMRC of your intention to disclose, you then have 90 days to calculate and pay what you owe, and HMRC reviews and accepts the disclosure. How far back you go depends on your behaviour, but for most cases involving a simple failure to take reasonable care, you'll typically need to cover six tax years. The financial logic is compelling: HMRC's data-matching is more powerful than ever, drawing on letting agent reports, Land Registry records and deposit scheme data, so coming forward voluntarily attracts far lower penalties than waiting to be caught.
Property Tax Specialists Who Get the Numbers Right
Making a disclosure sounds straightforward until you actually sit down to do it — and that's where getting expert help genuinely pays for itself. Backed by a CEO with more than 18 years of tax experience, our property tax team handles Let Property Campaign disclosures regularly and knows precisely how to structure them to put you in the strongest possible position. We start by confirming your correct look-back period, because disclosing too many or too few years can both cost you money. We then work carefully through your records to calculate the rental profit for each year, making sure every allowable expense is properly claimed — letting agent fees, repairs, insurance, mortgage interest relief under the current rules, and more — so you don't end up paying tax on income you never really kept.
We assess the right penalty position based on whether the non-disclosure was careless or simply an honest oversight, and we present the disclosure to HMRC clearly and professionally. For landlords with overseas property or more tangled affairs, our experience really comes into its own, as these cases need a careful, methodical hand. Just as importantly, we look forward as well as back: once your historical position is sorted, we make sure you're set up correctly going forward, whether that means registering for Self Assessment or preparing for Making Tax Digital. The result is a complete, accurate disclosure and a landlord who can finally stop worrying.
Discreet, Reassuring Help for Landlords Throughout the UK
The landlords we help through the Let Property Campaign almost always arrive feeling anxious and leave feeling enormously relieved — and that transformation is exactly what we aim for. Many are ordinary people who simply didn't realise rental income needed declaring, or who let things slide and then felt too frightened to come forward. We never judge; we just sort it out. Because our disclosure service runs entirely online as well as from our London office, we look after clients wherever they are, from landlords in Birmingham to expats letting out a former UK home from overseas. Secure portals let you share statements and records safely, and we keep you informed and reassured at every stage of the 90-day window.
We stay completely up to date with HMRC's evolving compliance approach, including the steady stream of "nudge" letters and the ever-widening data sources HMRC now uses, so our advice always reflects the current landscape rather than how things worked a few years ago. We also use modern accounting software to pull your rental figures together quickly and accurately, which keeps the process efficient and our fees fair. Speaking of which, our pricing is transparent and agreed upfront, so you'll know the cost before we begin. If you've received a nudge letter, or if you've simply been losing sleep over undeclared rental income, the smartest move is to talk to us before HMRC contacts you — a voluntary, prompted disclosure always beats being found out. A confidential, no-obligation chat is the easiest first step.
FAQs
1. What is the Let Property Campaign?
It's HMRC's voluntary disclosure facility for individual residential landlords who haven't declared all their rental income, allowing them to come forward with reduced penalties.
2. Is the campaign still open in 2026?
Yes. It has been open since 2013 and remains active, with no announced closing date — though HMRC's ability to detect undeclared income keeps growing.
3. Who can use it?
Individual residential landlords, including those with single or multiple properties, holiday lets, rooms let above the Rent a Room threshold, overseas property, and "accidental" landlords. It doesn't cover companies or commercial property.
4. How many years do I need to disclose?
It depends on your behaviour. Most cases involving a failure to take reasonable care require around six tax years; we confirm your exact look-back period.
5. How does the process work?
You notify HMRC, then have 90 days to calculate and pay what you owe, after which HMRC reviews and accepts the disclosure. We manage each stage for you.
6. Will I get a penalty?
Usually, but voluntary disclosure attracts far lower penalties than being caught. We assess the correct penalty position and aim to keep it as low as possible.
7. What if I can't pay it all within 90 days?
You can apply for a time-to-pay arrangement to spread the cost. We help you put this to HMRC where appropriate.
8. What if I've received a nudge letter from HMRC?
Act quickly. We assess your position and make a prompt, accurate disclosure, which still results in better treatment than ignoring it.
9. Do I need to register for Self Assessment going forward?
Often yes, if you'll continue receiving rental income. We set you up correctly for the future, including preparing for Making Tax Digital.
10. Can this be done online?
Yes. Our disclosure service is fully available online across the UK, as well as from our London office, with secure document sharing.
