Hi HMRC Admin 25, 32,
This is shocking level of incorrect information from HMRC agents.
If an individual works in the UK for a non-UK employer and the overseas company has no tax presence in the UK, they need to report the income on a DPNI scheme, not on a self-assessment tax return.
If they report it on a self-assessment tax return, class 1 NIC would not be calculated.
Also, if a UK based employee works in the UK, remittance basis CANNOT be claimed. If remittance basis is not claimed overseas workday relief cannot be claimed.
How are taxpayers expected to pay tax correctly if HMRC staff gives incorrect information?
