If you've earned rental income you haven't declared to HMRC — whether by mistake, oversight, or simply not knowing you needed to — the Let Property Campaign gives you a chance to come forward voluntarily and put things right, often with significantly reduced penalties compared to being caught first. Direct Assist Accountants guides landlords across Slough through the entire disclosure process, calculating exactly what's owed and handling communication with HMRC on your behalf.
The penalties HMRC applies depend heavily on whether you come forward first or whether they catch you. Voluntary disclosure through the Let Property Campaign typically results in penalties as low as 0-20% of the tax owed, while HMRC-initiated investigations can result in penalties up to 100% (or more for offshore income), plus the risk of criminal investigation in serious cases. The longer undeclared income goes unreported, the larger the tax, interest, and penalty bill grows — and the harder it becomes to present it as an innocent oversight. We help you act early, calculate accurately, and disclose on the best possible terms.

Criminal prosecution is rare and generally reserved for deliberate, large-scale fraud — voluntary disclosure through the Let Property Campaign is specifically designed to resolve genuine oversights without criminal consequences.
Typically up to 6 years for careless errors, but this can extend to 20 years if HMRC considers the non-disclosure deliberate — voluntary disclosure generally results in a shorter, more favourable review period.
Penalties under the Let Property Campaign are usually significantly lower than HMRC-initiated penalties, often in the 0-20% range depending on whether the error was careless or deliberate, and how promptly you disclose.
Yes, this is one of the most common situations the Let Property Campaign is designed for.
Yes, HMRC will often agree to a Time to Pay arrangement, and we can help negotiate a plan that fits your circumstances.
