Can HMRC see my Monzo account?
HMRC cannot access your Monzo account through open banking — that requires your explicit consent. However, HMRC has legal powers under the Finance Act and Tax Management Act to issue formal information notices to Monzo requiring the disclosure of account data in cases of suspected tax non-compliance. Monzo, as a fully licensed UK bank regulated by the FCA and PRA, must comply with such requests.
Does Monzo share data with HMRC automatically?
Monzo, like all UK banks, participates in automatic information exchange under the Common Reporting Standard (CRS) for accounts that meet reporting thresholds. It also reports interest earned on savings pots to HMRC. Monzo’s business accounts are subject to the same merchant income reporting obligations as traditional banks. Routine personal current account transactions are not automatically reported to HMRC.
What financial activity in Monzo might attract HMRC attention?
Significant unexplained deposits, high volumes of payments that appear to represent undeclared business income, or discrepancies between account activity and declared income can all attract HMRC scrutiny. HMRC’s Connect system cross-references data from multiple sources. This applies to Monzo in exactly the same way as it does to any high-street bank account — the bank’s app-based nature does not change HMRC’s legal access rights.
Open Banking in Practice: Monzo received its full UK banking licence in 2017 and is regulated by both the FCA and PRA. It operates under the same legal framework as Barclays or Lloyds with respect to HMRC data requests. Open banking connections to Monzo — for example, connecting your Monzo account to a budgeting app — are entirely separate from HMRC’s investigative powers.
