Yes, my opinion is kinda same. But chance to get audited is not so low. Total transferred amount is few hundred thousand usd and I was asking RD about that, so they probably remember me.
I'm curious about possible penalties if RD has different opinion (fifo vs lifo). Because the correct method isn't written anywhere, isn't it? Even when I asked their lawyer, she couldn't answer and said something like "I should know myself (?!) where is the capital and the income".
To be honest I think that any confrontation with them is lose-lose situation with high risks. I'm thinking about pay now and try to clarify it later (deadline is 9th April, so no time now). Can I request a refund later if I believe that tax was paid by mistake? They probably won't return it unless proper documentation is provided. This looks like a "safe" decision.
