I formed an LLC this year but barely made money can I file those taxes when filing my personal taxes even though I will be filing those married joint since we got married this month?
It kind of depends on the classification of your LLC. The IRS will treat it an LLC as either a corporation, a partnership, or as part of their tax return (usually on a Schedule C).
If you do not have a partner and you didn't make the election to be treated as a corporation, then you may be able to file it on your individual income tax return as a disregarded entity. https://www.irs.gov/businesses/small-businesses-self-employed/limited-liability-company-llc
If that applies to you, most people report it on a Schedule C for self-employment/business tax return. There you can report your proceeds and your expenses to see if you have a profit or a loss.
