Frequently asked questions
- Do I need Schedule C for one small gig?
- If income is from a profit-motivated business activity, generally yes—report on Schedule C even without 1099.
- Can I file Schedule C myself?
- Tax software handles it for straightforward cases. Complex depreciation or multi-state work benefits from CPA review.
- What if Schedule C shows a loss?
- Losses may reduce total income on 1040. Repeated losses risk hobby classification—document business intent.
- Does LLC require different form?
- Disregarded LLC uses Schedule C like sole prop. Partnerships and S-corps use other returns.
- Where do 1099-K amounts go?
- Include in gross receipts but reconcile fees and duplicates so you do not double-count platform and client 1099s.
- Is Schedule C the same as Schedule SE?
- No—Schedule C is profit/loss; Schedule SE calculates self-employment tax on that profit.
- Can I amend Schedule C later?
- Yes via Form 1040-X if you missed expenses or income—generally within three years for refunds.
- What accounting method goes on Schedule C?
- Most freelancers check cash method unless inventory forces accrual—consult CPA if unsure.
- Do I attach receipts to Schedule C?
- Not when e-filing—keep receipts for seven years in case of IRS question or audit.
