Small Business Taxes
The taxes that surprise the self-employed: self-employment tax and both halves of FICA, quarterly estimated payments, 1099 versus W-2, what you can write off, the home-office deduction, how LLCs are actually taxed, the QBI deduction, recordkeeping, and paying contractors on a 1099-NEC. The framework is durable, but the dollar figures change every year — always confirm current amounts at irs.gov.
