Frequently asked questions

What makes CirclesTax different from TurboTax or H&R Block?

CirclesTax is the only tax preparation software that links every calculation directly to IRS legal authority. Every deduction, credit, and computation cites the specific IRC section, Revenue Procedure, or IRS Publication that authorizes it. Other software tells you what your refund is — we show you exactly why.

Can I prepare my taxes online for free?

Yes. CirclesTax offers free federal tax preparation for Form 1040 returns. Every plan, including the free tier, includes IRS legal authority citations for all calculations. No credit card required to start.

What is the $29.99/year Records Vault fee?

Records Vault is optional. Filing preparation and PDF generation remain free. The $29.99 annual fee covers secure cloud record retention, prior-year retrieval, and audit-ready exports if you want us to host your records for you.

What does 'audit-proof' mean?

Audit-proof means every line of your tax return includes a reference to the specific IRS legal authority that supports it. If the IRS questions any deduction or calculation, you have the exact IRC section, Revenue Procedure, or IRS Publication ready as documentation.

What tax forms does CirclesTax support?

CirclesTax supports Form 1040 (Individual Income Tax Return) with Schedules A through SE, covering itemized deductions, interest and dividends, business income, capital gains, supplemental income, and self-employment tax.

Does CirclesTax submit my return to the IRS?

CirclesTax generates print-ready PDF documents with full IRS citation chains. You print and mail your return or use it with a separate e-filing service. Direct IRS e-filing integration is coming soon.

How do I know my deductions are legally defensible?

CirclesTax automatically cites the IRS legal authority for every deduction you claim. Each line item shows the specific IRC section number, Revenue Procedure, or IRS Publication. Your audit defense report compiles all of these into a single document.
