What is the Purpose of a Schedule C?

It is to be filled and filed by sole proprietors, running their own small business or working as independent contractors. If there are extra income sources that don’t come from your primary business activity, you need to fill corresponding schedules along with Schedule C. The IRS still accepts paper forms and schedules and even has printable PDFs and its own Form 1040 instructions.

Do I need to sign Schedule C 1040 form?

Yes, it has to be signed to be legit. An electronic signature (or an e-sign) is just as legit as your handwritten one.

What are tax schedules at all? Why not a simple form?

Schedules are just meant to make declaring easier. Instead of having one bedsheet of text to figure out, you only fill out and file the schedules that fit your income sources and activity.

Does the IRS accept electronic signatures on Schedule C?

The one who files a Schedule C for you should be your tax representative or an agent; yes, their signature will be legit. But in this case, you:

  1. need a reason to have someone do your work;
  2. must be sure that a person is eligible to practice before the IRS in order to represent you;
  3. are still responsible for the correctness of the data provided.
