Frequently Asked Questions

Does this handle Section 121 exclusion?

Yes. If the property qualifies as a primary residence and holding requirements are met, exclusion is applied to taxable gain.

How is depreciation recapture treated?

Depreciation recapture is estimated at a 25% federal rate on allowable recaptured depreciation up to realized gain.

Should I rely on this for filing?

Use it for planning only. Final tax filing should be done with a CPA or tax advisor.

Key Terms (Plain English)

Adjusted Basis

Original tax basis adjusted for improvements and depreciation.

Example: Higher adjusted basis generally reduces taxable gain.

Depreciation Recapture

Portion of gain tied to depreciation deductions, often taxed at a separate rate.

Example: Depreciation claimed over ownership may be recaptured at sale.

Section 121 Exclusion

Potential exclusion on primary-residence gains if IRS tests are met.

Example: Many filers can exclude up to $250k (single) or $500k (married) in qualifying cases.
