Failure to Notify Investigations
UK tax law places a clear obligation on individuals and businesses to notify HMRC of their tax liabilities. This includes registering for taxes such as Income Tax, Corporation Tax, VAT, and PAYE at the right time. If you fail to notify HMRC — whether by mistake or deliberately — you may face an investigation.
Why HMRC Investigates Failure to Notify
HMRC takes a tough stance on taxpayers who don’t come forward to declare their obligations. Common reasons investigations are triggered include:
- Starting a business but failing to register for tax.
- Not registering for VAT once turnover passes the threshold.
- Failing to register for PAYE when employing staff.
- Omitting rental or overseas income from self-assessment.
- Deliberate concealment of taxable activity.
HMRC cross-checks information from banks, employers, property transactions, and other government departments. If they find inconsistencies, they will often open a full enquiry.
What’s at Risk in a Failure to Notify Investigation The consequences can be serious and far-reaching:
- Backdated tax bills covering all undeclared years.
- Substantial penalties, which can be up to 100% of the unpaid tax.
- Interest charges on late payments.
- Increased scrutiny in future, with HMRC monitoring your tax affairs more closely.
- In severe cases, criminal prosecution for deliberate tax evasion.
Even if your failure to notify was unintentional, HMRC may still impose penalties unless you can demonstrate reasonable care.
