California Form 593 Real Estate Withholding: What Sellers Should Review Before Closing

Review the primary official source.
What California Real Estate Withholding Actually Is
When a California property changes hands, state law generally requires that a portion of the seller's proceeds be withheld and sent to the Franchise Tax Board. This mechanism exists to collect estimated tax from sellers who might otherwise have no further California filing obligation after the sale closes.
It is important to understand from the outset that withholding is a prepayment toward potential tax liability, not a final tax determination. Whether you ultimately owe California tax on the gain, and how much, depends on your complete tax picture for the year — not on the withholding amount alone. The FTB's 2026 Form 593 instructions make this distinction explicit.
Form 593 is the document that drives this process. It serves two related purposes: it allows sellers to certify a qualifying exemption from withholding, and it supports the calculation of the correct withholding amount when no full exemption applies. Escrow officers rely on the completed form to determine what, if anything, to remit to the FTB on your behalf.
Because errors on Form 593 can result in over-withholding that ties up your proceeds or under-withholding that creates compliance problems, reviewing the form carefully before closing is worth the time. This article is general education, not legal or tax advice, and your specific facts will determine what applies to you. Consider consulting a qualified professional — see our overview of tax attorneys, CPAs, and enrolled agents to understand which type of help fits your situation.
Seller Identity, Ownership Records, and Exemption Certifications
Form 593 begins with seller identification, and the information entered there must match your ownership records precisely. If title involves a trust, LLC, partnership, corporation, or multiple owners, the seller information and ownership allocation require careful review under the form instructions.
Several exemptions can reduce or eliminate withholding, and each requires a certification that you can support with documentation. Common exemptions addressed in the 2026 instructions include:
- Principal residence exemption: The property was your principal residence and you meet the relevant ownership and use requirements. You will need to be able to substantiate this claim.
- Loss or zero-gain certification: You certify that the sale will result in a loss or no taxable gain for California purposes. This requires a reasonable basis in your actual numbers.
- Certain entity or transaction types: Specific seller categories or transaction structures may qualify under conditions described in the instructions.
Certifying an exemption you cannot support is a serious matter. Review your title documents, residency history, and purchase records before checking any exemption box. The FTB's real estate withholding guidelines provide additional context on how these rules are applied.
Withholding Calculations, Installment Sales, and Escrow Handling
When no full exemption applies, Form 593 offers more than one method for calculating the withholding amount. The standard approach applies a percentage to the gross sales price. An alternative method bases withholding on the estimated gain, which can result in a lower withholding amount if your actual gain is modest relative to the sale price.
Choosing the alternative calculation requires completing the gain worksheet in the instructions and being prepared to support the figures used. Errors in basis, depreciation recapture, or selling costs can distort the result, so accuracy matters here.
Installment sales add another layer of complexity. If you will receive payments over time rather than a lump sum at closing, withholding rules apply differently to each installment payment. The 2026 instructions address this scenario, and sellers using installment arrangements should review that section carefully before the first payment is received.
On the escrow side, keep the following in mind:
- Escrow is responsible for submitting the withheld amount to the FTB, but the seller completes and signs Form 593.
- Request a copy of the completed Form 593 for your records before or at closing — you will need it when you file your California return.
- Confirm that the withholding amount shown on the form matches what escrow actually remits.
- If you are selling multiple parcels in a single transaction, verify how each is treated on the form.

After Closing: Claiming Your Credit on the California Return
Withholding remitted to the FTB does not disappear — it is credited against your California income tax liability for the year of the sale. If the withheld amount exceeds what you actually owe, you may be entitled to a refund. If the credit is less than the final liability after other payments and credits, a balance may remain when the return is filed.
To claim the credit, you will report the withholding on your California return using the information from your copy of Form 593. This is why retaining that document is essential. A mismatch between what escrow remitted and what you report can delay processing or trigger FTB correspondence.
The withholding amount does not determine your gain, your tax rate, or your final liability. Those figures come from your complete California return, including all income, deductions, and applicable adjustments for the year. Sellers sometimes assume that because withholding was taken, the tax obligation is settled — it is not.
As concrete next steps before your closing date, consider the following checklist:
- Confirm that seller name and entity information on Form 593 match your title documents exactly.
- Gather documentation to support any exemption you plan to certify, including residency records or basis calculations.
- If using the alternative gain-based withholding method, prepare and review the gain worksheet before signing.
- Ask escrow for a copy of the completed Form 593 and confirm the remittance amount.
- If your sale involves an installment arrangement, clarify how withholding will be handled on future payments.
- Retain all closing documents and provide your Form 593 copy to whoever prepares your California return.
- Review the FTB's withholding guidelines and the 2026 Form 593 instructions with a qualified tax professional who can apply them to your specific facts.
