How Much Should I Save for 1099 Taxes?

There is no universal guaranteed percentage. A useful reserve starts with projected profit and the tax layers and household facts that apply to the year.

Last reviewed: August 6, 2026

Quick answer

Estimate self-employment tax and federal income tax separately, add state or local considerations, then subtract expected withholding, credits, and payments already made. Revisit the reserve as income and expenses change.

Why one percentage cannot fit everyone

Two workers with the same 1099 receipts can have different business expenses, filing statuses, household income, withholding, credits, states, and payment histories. Gross receipts also differ from net business profit.

Start with self-employment tax

Self-employment tax commonly relates to net earnings from self-employment and is distinct from federal income tax. W-2 wages and other facts can affect parts of the calculation.

Add federal income-tax planning

Federal income tax uses taxable-income concepts, filing status, deductions, brackets, credits, and other return-level facts. Applying one flat percentage to gross receipts hides those differences.

Review state, local, and household factors

State and local rules vary. Other household income, a spouse's income, withholding from another job, deductions, credits, and prior payments may raise or lower the uncovered amount.

Reserve cash is not final liability

A reserve is cash set aside for planning. It is not a filed payment, a safe-harbor conclusion, or the final amount shown on a return. Keep payment confirmations separate from money that remains in savings.

Build the estimate in layers

  1. Reconcile gross business receipts and supported expenses.
  2. Estimate self-employment tax on preliminary net earnings.
  3. Estimate federal income tax using the broader household projection.
  4. Add current state or local planning where applicable.
  5. Subtract expected withholding, credits, and payments already made.
  6. Divide the remaining reserve across realistic pay periods and update it after material changes.
