can I file my full years income through the LLC?
No. Assuming this is a single member LLC (you are the one and only owner of the business) your business income and expenses will be reported on SCH as a physical part of your personal 1040 tax return. Weather you're filing joint or single doesn't matter. It still gets reported on SCH C as a physical part of your personal 1040 tax return.
So can you file your income through the LLC? Absolutely not. It's exactly the opposite. All of your LLC income received in the tax year is reported on SCH C as a part of your personal tax return. Nothing gets filed "though" anything. It all gets filed "with" your personal 1040 return.
