I have a client who does payroll and taxes and is looking for a web app to easily communicate and transfer tax related documents for clients. I would assume that the IRS or someone would have some standard on how this type of data should be handled. I haven't been able to find any good information on the subject and I don't know enough about the business domain of taxes yet to know how to ask for the information I am looking for. Any help, resources, suggestions would be great.

The IRS has published Publication 1075 which provides "Safeguards for Protecting Federal Tax Returns and Return Information"

Internal Revenue Code Section 6103 stipulates that IRS must protect all the personal and financial information furnished to the agency against unauthorized use, inspection or disclosure. Other Federal, State and local authorities who receive federal tax information (FTI) directly from either the IRS or from secondary sources must also have adequate security controls in place to protect the data received.

Publication 1075 is very broad and deep. Section 4 discusses Secure Storage, and Section 9 focuses on Computer Security Systems.

You should also look at FIPS 140-2 for additional encryption details.
