For years, a non-resident Pakistani running a US LLC from Lahore could operate with a reasonable expectation of limited scrutiny. Income held offshore, accounts in Pakistan, a UK bank account from your time in Manchester - none of it was automatically visible to anyone.
That is no longer the case.
Pakistan joined the Common Reporting Standard (CRS). That decision means Pakistani banks - HBL, MCB, UBL, all of them - are legally required to report account holder information to the Federal Board of Revenue (FBR). The FBR then shares that data with participating foreign tax authorities, including HMRC. Under separate FATCA agreements, similar data flows toward the IRS.
"The mismatch that gets NRPs flagged is not always some complex offshore structure. It can be as simple as a Lahore-based founder reporting modest UK consulting income on their SA100 while their Meezan Bank account shows a significantly larger balance."
The system flags the gap. An inquiry follows.
By 2026, both the IRS and HMRC have expanded their use of machine-learning tools to cross-reference CRS-reported data against self-filed returns at scale. The gap between what your bank reported and what you filed is not a private discrepancy anymore. It is a queue item in an automated system.
The only position with any real control left is disclosure before the flag is generated.
