How this calculator works

Estimate a potential taxable residential property gain under the two-year bright-line test.

Formula

A gain is tested against dates and user-confirmed exclusions before entering the individual tax brackets.

Worked example

Other land-sale rules may still apply outside bright-line.

Scope and edge cases

Eligibility, tax codes, certificates, multiple income sources and annual reconciliation can change the final outcome. Missing components are disclosed instead of silently becoming zero.
