Questions firms ask before using this calculator.
Does this cover every Section 121 edge case?
No. It is built for planning and discussion, not as a substitute for final return-level review of every residence or mixed-use detail.
Can this help explain the rule to clients visually?
Yes. The tool is designed to make timing tests and gain exclusion easier to explain in a client meeting or follow-up.
Is this only for homeowners?
The public page speaks to CPA firms and advisors, but it is especially useful when a client needs quick guidance before a primary residence sale.
