Tax Strategy for 1099 freelancers
A general freelancer has no single dominant deduction, so the discipline is in the record-keeping rather than the categories. Home office, health insurance, retirement plan contributions, and professional development are the four that most often go unclaimed, and the health insurance deduction in particular can be significant because self-employed workers are not covered by an employer plan.
General freelance income is the least predictable of any category here, often built from several unrelated clients. Because revenue concentration is itself a risk, base vouchers on the trailing twelve months and consider making quarterly payments even in a weak quarter, since the underpayment penalty is calculated on what you actually paid versus what you owed.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
