Form 7203 item C What is Stock Block

like if you were to purchase stock through a broker each time you buy that s a block.

in theory, every time you put money in that's a block. however, for an s-corp that would require tracking separate basis or each block and would require per share per day allocations.

most of the time there is no stock actually issued. so the easiest is to assume you only have 1 block. this would be especially true for an LLC that elected S-corp taxation because there is no stock.

When I did a recent return, that box was highlighted on the review. I had never had it prompted before and didn't have a clue what it wanted. So glad I found it here.
