Rental income was omitted

Expert perspective
The quality of the disclosure matters as much as the calculation.
The Let Property Campaign is a route for individuals to disclose previously undeclared residential property income. It may cover UK or overseas property depending on the facts, but companies and some other taxpayers need a different route.
A disclosure requires more than total rent less guessed expenses. We reconcile bank records, agent statements, mortgage interest and ownership, distinguish capital works and decide how far back the review must go based on the taxpayer’s behaviour and legal time limits.
The accompanying explanation should be candid, consistent with the numbers and supported by evidence. We help notify HMRC, calculate tax, interest and an appropriate penalty offer, submit within the required window and bring subsequent returns up to date.
When this matters
Recognise the point at which advice adds value
The best result usually comes from reviewing the position before documents are signed, money moves or a filing deadline becomes urgent.
Only part of the income was declared
One property, platform, period or owner’s share was missed, or expenses and finance costs were handled incorrectly.
HMRC has written to you
A prompted letter, data-matching query or compliance check means the response route and deadlines need immediate attention.
You want to sell or refinance
Historic compliance needs resolving before a transaction, mortgage application or due-diligence process exposes inconsistencies.
The technical review
The areas we bring into one review
Good advice connects the tax analysis to the records, legal steps, cash position and longer-term objective.
Correct route
Let Property Campaign eligibility versus an amended return, contractual disclosure facility or other HMRC process.
Years in scope
When the obligation began, filing history, HMRC discovery rules and behaviour that determines statutory time limits.
Rental reconstruction
Gross income, ownership shares, agent deductions, allowable expenses, finance costs, losses and capital items.
Behaviour and penalties
Reasonable care, carelessness or deliberate conduct assessed from the real history, with disclosure quality and cooperation considered.
Interest and payment
Tax by year, payments on account, late-payment interest, penalty offer and ability-to-pay communication where needed.
Future compliance
Registration, current-year records, digital processes and returns aligned so the same problem does not repeat.
What changes the answer
How the omission happened changes both the period and the penalty.
Behaviour must be explained honestly and supported by the sequence of events, not selected simply to produce the lowest percentage.
- 01Which taxpayer and ownership share should have reported the income in each year?
- 02When was the error first understood, and has HMRC already made contact or opened an enquiry?
- 03What records exist and where are reasonable estimates genuinely unavoidable?
- 04What conduct led to the omission and what steps were taken once it was identified?

Questions worth asking
Frequently asked questions
Who can use the Let Property Campaign?
It is principally aimed at individual landlords, including people letting a single property. Companies, trusts and certain other cases need a different disclosure or return route.
How many years must be disclosed?
The period depends on filing history and whether the behaviour was reasonable, careless or deliberate. It is not automatically the same for every taxpayer and should be assessed before figures are finalised.
What if I do not have complete records?
We use bank data, agent statements, mortgage records, invoices and third-party evidence. Reasonable estimates may be needed, but the methodology and limitations should be disclosed rather than presenting guesses as exact.
Can I claim expenses in the disclosure?
Yes, to the extent they were allowable for the relevant year and can be supported. Capital improvements and mortgage principal are not annual rental expenses, and finance-cost rules changed over time.
Is an HMRC letter still a voluntary disclosure?
A disclosure after HMRC contact may be prompted, which can affect penalty ranges and negotiation. The exact letter and any response deadline should be reviewed immediately.
What happens after the disclosure is submitted?
HMRC may accept it, ask questions or propose changes. You must also ensure current and future returns are correct. We can manage agreed correspondence and ongoing compliance.
