From 2017 UK brokers including Interactive Brokers have started to automatically report information on account balances, interest, dividends, gross proceeds etc. to the tax authorities in other EU countries. When I compare the account balance and interest that Interactive Brokers UK has reported to the tax authorities in my country, it corresponds to the equivalent reported on IB’s default activity statement except for what can be attributed to rounding error on FX. However, I find it difficult to reconcile dividends. I have of course omitted payments in lieu of dividends, and I have added dividend withholding tax, but still a discrepancy larger than what can be attributed to rounding error remains. Has anyone experienced difficulties reconciling dividends reported to the tax authorities with dividends stated on IB’s default account statement?
