California Home-Seller Tax Planning Checklist
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
Tax planning should begin before closing because basis records, withholding forms, foreign-seller documentation, ownership issues, and professional review can take time to resolve.
Before listing

- Gather improvement records
- Review rental or business use
- Obtain depreciation schedules
- Document inheritance, gift, trust, or divorce history
- Estimate adjusted basis
- Estimate selling expenses
- Identify all owners
- Consult a qualified tax professional
Before accepting an offer
- Estimate gain separately from net proceeds
- Review potential home-sale exclusion
- Confirm residence and ownership dates
- Consider partial-exclusion questions
- Review California-source income
- Evaluate multistate tax issues
- Identify FIRPTA concerns
- Review Proposition 19 timing if applicable
- Avoid relying on an agent or escrow officer for tax advice
During escrow
- Review the current California Form 593
- Determine whether an exemption may apply
- Compare permitted withholding methods
- Confirm taxpayer identification information
- Coordinate foreign-seller documentation
- Update the estimated gain for credits and expenses
- Preserve signed documents
- Verify wire instructions independently
After closing
- Save the final settlement statement
- Save Form 593 and FIRPTA records
- Confirm proceeds and withholding
- Provide records to the tax preparer
- File required federal and state returns
- Claim available withholding credits correctly
- Preserve the complete property file
- Update estate and financial records
Frequently Asked Questions
Can the brokerage tell me exactly how much tax I will owe?
No. The brokerage can help organize transaction information, but tax calculations belong with qualified tax professionals.
Should tax planning affect my listing date?
Possibly. Ownership, residence, exchange, installment-sale, Proposition 19, residency, and tax-year timing may matter.
What is the most important distinction?
Do not confuse sale price, equity, net proceeds, taxable gain, withholding, and final tax. They are different numbers.

A note on legal advice: These guides provide general, educational information about California real estate practice. They are not legal advice and do not create an attorney-client relationship. Mortgage information is general education, not individualized lending, tax or legal guidance. For advice about your specific offer, contract, closing or financing, consult a qualified California real estate attorney and a qualified mortgage professional.
A note on these tax guides: The California home-sale tax articles provide general educational information and have been reviewed by a qualified California tax professional. They are not tax, legal, accounting, financial, or insurance advice, and JC Pacific Corp and its real estate professionals are not tax advisers. Sale price, equity, net proceeds, taxable gain, withholding, and final tax are different numbers, and withholding is a collection mechanism, not a determination of final tax liability. Verify current IRS and California Franchise Tax Board forms and rules with a qualified tax professional before making decisions.
