Investors & landlords

I question how Ally Invest is able to skirt IRS requirements to postmark all 1099s by midnight, Jan 31st? Effectively, they should be available electronically by the morning of Feb 1st.  This is a Federal requirement, subject to a $50 fine per occurrence.  How do they, year after year, only START mailing 1099Bs, DIV, etc, during the second or third week of February, without incurring, likely millions, of $50 penalties?
