There isn’t one single “best” calculator for everyone, but for self-employed filers who expect an estimated balance due, the best option is usually the IRS Online Payment Agreement/Installment Agreement tools plus a separate estimated tax calculator.

Best choices depending on what you need

1) If you want the most reliable, official option:

  • IRS Estimated Tax Worksheet (Form 1040-ES)
    • Best for figuring out how much to pay each quarter.
  • IRS Online Payment Agreement calculator/tools
    • Best if you already have a balance due and want to spread it out.

2) If you want an easy-to-use planning calculator:

  • TaxAct Estimated Tax Calculator
  • TurboTax Self-Employed tax estimator
  • 1040.com estimated tax calculator
  • SmartAsset tax calculators
    These are usually easier to use than IRS forms, but they’re not as authoritative as IRS tools.

What I’d recommend

  • For ongoing self-employment tax planning: use an estimated tax calculator.
  • For a tax bill you already owe: use the IRS payment plan / installment agreement tool.

Important note

If you’re self-employed, you generally need to account for:

  • income tax
  • self-employment tax
  • possible state estimated taxes

If you want, I can help you pick the best calculator based on your situation:

  • how much you owe
  • whether it’s federal only or state too
  • whether you want monthly payments or quarterly estimates
