California real estate withholding is not just a closing formality. For investors, nonresident owners, trusts, estates, LLCs, and sellers structuring installment sales or 1031 exchanges, California Form 593 can determine whether sale proceeds remain available to the seller at closing or are withheld and remitted to the Franchise Tax Board until the seller files a California tax return.
The 2026 Form 593 instructions are clear about timing: a seller that wants to prevent withholding must submit the form before the real estate transaction closes. After closing, withheld amounts generally cannot be unwound through escrow. The seller recovers the amount by claiming the withholding credit on the appropriate California return. That timing pressure makes Form 593 a planning item, not a last-minute signature package.
How Form 593 works
California Form 593 is used to certify a full, partial, or no withholding exemption, estimate loss or zero gain, calculate alternative withholding, and report real estate withholding on 2026 closings, 2026 installment payments, and completed or failed exchanges in 2026.
If no exemption or alternative calculation applies, withholding is typically computed at 3 1/3% of the sales price, boot, failed exchange amount, or applicable installment payment. In some cases, the seller may elect an alternative withholding calculation based on estimated gain and the applicable tax rate. That election can be valuable, but only if the gain calculation, basis support, ownership percentage, and signatures are ready before escrow needs the form.
Mistake 1: Waiting until the closing table
The most costly Form 593 problem is timing. Sellers often focus on the purchase agreement, loan payoff, 1031 identification deadlines, or distribution instructions, while Form 593 sits in the escrow package until closing week.
By then, it may be too late to model gain, obtain trust or entity taxpayer identification numbers, coordinate spouse or co-owner signatures, or document a loss or zero-gain certification. Sellers should review the FTB’s real estate withholding guidance early in escrow, especially when the property has depreciation, refinance proceeds, inherited basis, multiple owners, or an exchange structure.
Mistake 2: Assuming nonresident withholding is the same rule
California real estate withholding is related to nonresident compliance, but it has its own Form 593 mechanics. Aura previously covered California nonresident withholding requirements for non-wage payments. Real estate sales use a separate process.
That affects which form is used, who signs, what exemption applies, and when withholding is remitted. A seller should not assume that Form 590, Form 588, or a general nonresident withholding analysis will solve a California real estate sale.
Mistake 3: Trusts on title
FTB guidance for trust-owned property is specific. A grantor trust generally reports the individual grantor’s name and SSN or ITIN, not the trust or trustee. A nongrantor trust typically reports the trust name and FEIN. A grantor trust that became irrevocable after death can require different treatment.
This is where estate administration, title records, and tax reporting need to align. The wrong seller name or identification number can delay processing or put the withholding credit in the wrong taxpayer’s account causing a matching error or notices when returns are filed.
Mistake 4: Overlooking LLC and entity seller rules
LLCs and partnerships require their own review. The Form 593 instructions address LLCs taxed as partnerships, disregarded single-member LLCs, corporations, S corporations, and entities qualified to do business in California. Even when withholding is not required on the entity sale, the entity may still have withholding obligations for nonresident members or shareholders.
Before signing the certificate, confirm the tax classification, California registration status, title holder, member residency, and owner-level withholding obligations.
Mistake 5: Treating installment sales like ordinary closings
Installment sales can move withholding beyond escrow. During escrow, the real estate installment sale process may require withholding on the down payment, a copy of the promissory note, and Form 593-V when payment is remitted. After escrow, the buyer or transferee may have continuing withholding and reporting obligations on principal payments.
For a seller, this should be negotiated and documented before the note is signed. For a buyer, it is a compliance responsibility that can last for years.
Mistake 6: Missing the 1031 exchange withholding trigger
A 1031 exchange does not automatically remove California withholding. Form 593 addresses boot, failed exchanges, and cash-poor exchange situations. If boot is distributed or an exchange fails, withholding may apply using the year tied to the exchange completion, failed exchange, or distribution date.
Additionally, if a California property was previously exchanged for an out-of-state property in a Section 1031 exchange, California usually continues to track the deferred California gain. When the replacement property is later sold, all or a portion of that previously deferred gain may become subject to California tax, even though the property is no longer located in California. This is commonly referred to as the California “clawback” rule and is tracked annually on California Form 3840.
Investors considering a 1031 exchange should coordinate the qualified intermediary, escrow officer, and tax advisor early. The exchange strategy, withholding treatment, California reporting, and cash needs should be modeled together.
A practical pre-closing checklist
Before closing, sellers should confirm:
- Who the seller is for tax purposes
- Whether each owner needs a separate Form 593
- Eligibility for a full or partial withholding exemption
- Whether a loss, zero-gain, or alternative withholding calculation is supportable
- Use of the correct tax-year version of form 593
- Completion of all required signatures and perjury statements
- The impact of an installment sale, 1031 exchange, boot, failed exchange, or cash-poor transaction on the reporting requirements
- Whether withheld amounts and copies will be reported to the correct taxpayer
