Let Property Campaign Accountant for Undeclared Rental Income

The Let Property Campaign gives individual landlords a route to disclose previously undeclared residential rental income to HMRC. The disclosure needs to identify the correct years, rental profits, interest, penalties and other relevant undeclared liabilities rather than simply total up rent received.

We begin with the ownership and reporting history. A landlord who never registered for Self Assessment can have a very different look-back period from someone who filed returns but made a careless error, and recent years may need to be dealt with through an outstanding or amended tax return rather than included in the campaign disclosure.

Direct answer

What Does a Let Property Campaign Accountant Review First?

The first questions are who owns the property, when letting began, whether Self Assessment returns were filed and why the rental income was not correctly reported.

The practical answer

A Let Property Campaign Accountant Should Reconstruct Rental Profit Year by Year

HMRC needs the tax liability, not simply gross rent. Each relevant year should reflect rental income, allowable expenditure, the applicable finance-cost treatment, losses, the taxpayer's other income and any tax already paid.

Ownership The disclosure should follow the individual's actual taxable share of the rental income.
Years The look-back period depends on filing history, failure to notify and taxpayer behaviour.
Rental profit Allowable expenses and relevant property losses need to be reconstructed for each tax year.
Penalties Behaviour and whether HMRC has already prompted the disclosure can affect the penalty position.
Service scope

Let Property Campaign Disclosure Work We Can Review

The service covers the historic property calculation, disclosure mechanics and the landlord's ongoing tax reporting so that the position is brought fully up to date.

01 / OWNERSHIP

Property ownership

We establish who owned the property and how rental income should be allocated between joint owners.

02 / RENT

Historic rental income

Letting-agent statements, bank deposits and direct rental receipts are reconstructed for each relevant year.

03 / COSTS

Allowable expenditure

Repairs, management, insurance, finance costs and other expenditure are reviewed under the rules applying to the relevant year.

04 / YEARS

Disclosure period

The filing history and behaviour are reviewed before deciding how many historic years belong in the disclosure.

05 / PENALTIES

Interest and penalties

Late-payment interest and the appropriate penalty position are calculated alongside the underlying tax.

06 / FUTURE

Ongoing landlord compliance

Current and future rental income is brought into the appropriate Self Assessment or MTD process rather than left inside the historic disclosure.

How the engagement works

From Undeclared Rent to a Complete Let Property Campaign Disclosure

The campaign has a notification stage followed by a defined disclosure period, so the underlying records should start being reconstructed as soon as the disclosure route is confirmed.

01 / REVIEW

Establish the history

We identify the properties, ownership, first letting dates, tax-return history and HMRC contact.

02 / NOTIFY

Notify HMRC

Where the campaign is appropriate, HMRC is notified of the intention to disclose and issues the relevant references.

03 / CALCULATE

Reconstruct the liability

Rental profits, other relevant undeclared income, tax, interest and penalties are calculated.

04 / DISCLOSE

Submit and settle

The formal disclosure and offer are submitted with payment or an agreed payment arrangement within the applicable deadline.

Who the campaign is for

The Let Property Campaign Is Primarily an Individual Landlord Disclosure Route

The campaign is designed for individual landlords with undeclared residential letting income. The property can be in the UK or overseas, but the taxpayer must have a UK tax liability requiring disclosure.

01 / UK PROPERTY

UK residential landlords

Individuals who have failed to declare all or part of the taxable income from residential property in the UK can potentially use the campaign.

02 / OVERSEAS

Overseas residential property

The campaign can also cover an individual landlord's undeclared taxable income from residential property located outside the UK.

03 / JOINT

Joint property owners

Each owner makes a separate disclosure for their own share. A husband and wife or civil partners do not make one combined campaign disclosure.

04 / OTHER OWNER

Companies and trusts

The individual-landlord campaign should not simply be used for company or trust liabilities. The correct entity-specific disclosure or tax-return process needs to be identified instead.

The campaign is not limited to landlords who own a large portfolio. A single inherited home, former main residence, jointly owned house or property rented while working elsewhere can all create undeclared taxable rental income.

Years and deadlines

The Number of Years in a Let Property Campaign Disclosure Depends on Why the Tax Was Underpaid

The historic period is not automatically the same for every landlord. HMRC's current campaign guidance distinguishes reasonable-care errors, careless errors, failure to notify and deliberate behaviour.

90 days After HMRC acknowledges the campaign notification, the disclosure and payment are normally due within 90 days of the acknowledgement date.
Up to 4 years Where the taxpayer registered on time and took reasonable care but still underpaid tax, HMRC's campaign guidance refers to a maximum four-year period.
Up to 6 years Where the taxpayer registered on time but the error resulted from careless behaviour, the campaign guidance refers to a maximum six-year period.
Up to 20 years Failure to notify HMRC of the rental income or deliberate behaviour can extend the disclosure period to a maximum of twenty years.

Recent tax years need particular care. HMRC's guidance states that current-year rental income should be dealt with through the appropriate current return, and income for a recent year may belong on an outstanding or amendable Self Assessment return rather than being duplicated in the campaign disclosure.

Frequently asked

Let Property Campaign Questions

The years, tax and penalty result depend on the landlord's reporting history and why the rental income was not correctly declared.

Who can use the Let Property Campaign?

HMRC's campaign is aimed at individual landlords with undeclared taxable income from residential property in the UK or abroad. Other ownership structures can require a different correction route.

How long do I have after notifying HMRC?

Once HMRC acknowledges the notification, the disclosure and payment are normally due within 90 days of the acknowledgement date.

How many years does the Let Property Campaign go back?

It depends on why the tax was underpaid. HMRC's current campaign guidance refers to a maximum of four years for reasonable-care errors, six years for careless errors and up to twenty years in relevant failure-to-notify or deliberate cases.

What if my property is jointly owned?

Each owner should disclose their own taxable share. HMRC requires separate notifications and disclosures for separate individuals rather than one joint disclosure.

Can I use the campaign for an overseas rental property?

Yes, an individual can potentially use the campaign for undeclared taxable rental income from residential property abroad. Residence, foreign tax and offshore penalty issues may require additional review.

What if I do not have old letting statements or bank records?

The records should first be reconstructed as far as reasonably possible. HMRC permits reasonable estimates where records genuinely cannot be obtained, but the basis of those estimates should be retained and capable of explanation.

Does a rental loss need to go into the disclosure?

HMRC's campaign guidance states that a year with no additional tax liability because the rental business made a loss does not itself need to be included as a tax-paying disclosure year, although the loss calculation can be relevant to later rental profits.

What if HMRC has already contacted me about the property?

The correspondence should be reviewed before notifying under the campaign. Prior HMRC contact can affect the penalty position and, depending on the stage and nature of HMRC's action, may affect how the matter should now be handled.
