I have a Schedule C income and a separate (but same business) Schedule K partnership loss on running the office for the business. How can I get the loss to offset Schedule C income, thus reducing SS tax I have to pay?
The partnership losses on the K-1 and the Sch C income will net automatically on the Sch SE.
Not on Schedule C but on Schedule SE for the self employment tax.
Here is Schedule SE. See page 2 line 2
