The short answer: If you're buying a California home and hoping to close before the new year, plan around three things. First, federal law requires you to receive your Closing Disclosure at least three business days before closing, and Thanksgiving (November 26) and Christmas (December 25) don't count as business days. Second, the first installment of your property tax bill goes delinquent December 10, and as the new owner you're responsible for any tax not paid when escrow closes. Third, December 31 decides which year's tax return your deductible closing costs land on, if you itemize.

As of November 12, 2026. Holiday dates and tax rules come from the agencies cited below; ask your tax preparer how they apply to you.

Why does the holiday calendar matter for my closing date?

Because of the Closing Disclosure "three-day rule." Your lender must make sure you receive the Closing Disclosure at least three business days before you sign. For this rule, a business day is every calendar day except Sundays and federal legal holidays, according to the American Land Title Association's guide to the rule (ALTA). So Saturdays count, even if your escrow office is closed, and holidays don't.

This year's holidays near the end of escrow season are Thanksgiving on Thursday, November 26, Christmas on Friday, December 25, and New Year's Day on Friday, January 1, 2027 (FedTools, 2026 federal holidays; 2027).

Here's how that plays out. These are hypothetical schedules to show the counting; your lender sets the real timeline:

  • To close Monday, November 30, you'd need the Closing Disclosure by Wednesday, November 25. Friday the 27th, Saturday the 28th and Monday the 30th are the three business days; Thanksgiving and Sunday are skipped.
  • To close Tuesday, December 29, you'd need it by Thursday, December 24. Christmas and Sunday are skipped.
  • To close Thursday, December 31, you'd need it by Monday, December 28.

One more catch: certain late changes restart the clock with a new Closing Disclosure and another three-day wait. ALTA lists an APR change of more than 1/8 of a percentage point on most loans, a change in loan product, or adding a prepayment penalty. Late changes are exactly what holiday-season delays tend to cause, so build in a few days of cushion.

Who pays the December 10 property tax installment?

In Los Angeles County, the first installment of the annual secured property tax bill is due November 1 and delinquent December 10; the second is due February 1 and delinquent April 10 (LA County property tax portal).

The LA County Treasurer and Tax Collector says "secured property taxes are prorated between the buyer and the seller during escrow," but also that "as a new owner, you are responsible for any taxes that were not paid as of the time escrow closed." The annual bill may go to the previous owner or to you, and the county says it's your responsibility to get it (LA County TTC, New Property Owners).

So if you close in late November or early December, ask your escrow officer one plain question: is the first installment being paid through escrow, and if not, who's paying it by December 10? If you're setting up an impound account, ask your lender the same thing. I wrote about the 2026–27 LA County bill and its deadlines last month.

What's the "supplemental" tax bill I'll get later?

California reassesses a property as of the first day of the month after it changes hands. If the new value is higher, you'll get one or more supplemental bills on top of the regular annual bill. LA County says supplemental bills "are generally issued between three months to one year after you acquired the property," are mailed directly to the owner, and "in general, they are not paid out of your impound account" (LA County property tax FAQ). Each has its own due date, printed on the bill.

This surprises a lot of buyers in the spring after a holiday closing. Set the money aside now, and when the bill arrives, tell your lender, as the county recommends.

Does closing before December 31 help at tax time?

It can, if you itemize. IRS Publication 530 says you can deduct mortgage interest you pay at settlement, and your share of real estate taxes paid at closing, if you itemize on Schedule A (IRS Publication 530). Points on a loan to buy your main home can be deducted in full in the year paid if you meet the IRS tests, including that you bring at least that much of your own money to closing and the points show clearly on your settlement statement. Seller-paid points can count too, as long as you subtract them from your purchase price for tax basis (IRS Topic 504).

The catch: "If you itemize, you can't take the standard deduction," as Publication 530 puts it. For many buyers, a December closing doesn't change their tax bill at all. If you're already near the line, it might. That's a question for your tax preparer, not something to rush a closing over. If you're thinking about prepaying property tax for the same reason, I covered the 2026 SALT cap rules separately.

What is "prepaid interest" on my Closing Disclosure?

The CFPB defines prepaid interest as interest "that accrues on your loan" between "the date you close" and "the period covered by your first monthly mortgage payment." It shows up on page 2, Section F, of both your Loan Estimate and Closing Disclosure, and the amount can change between the two (CFPB). Closing later in the month generally means fewer days of prepaid interest due at the table. It doesn't lower the total interest you pay over the loan, so choose your date for the move, the lock and the paperwork, not just this line.

Derek\'s take

December closings are very doable. When one goes wrong, it's rarely the loan; it's a holiday nobody counted, a Closing Disclosure that had to be reissued on December 23, or a property tax installment everyone assumed someone else was paying. If you're in escrow now, ask for a calendar that works backward from your closing date with the holidays marked, line up your funds early, and keep your rate lock long enough to cover a slip. I wrote this week about why locks matter more right now. If you'd like me to look at your timeline, book a call with me. Thirty minutes, no credit pull, no obligation.

Frequently asked questions

Does Saturday count for the Closing Disclosure three-day rule?

Yes. For this rule, a business day is every calendar day except Sundays and federal legal holidays, so Saturdays count even if your escrow or lender's office is closed.

Can I close the day after Thanksgiving?

The day after Thanksgiving isn't a federal holiday, so it counts for the Closing Disclosure clock. Whether you can sign and record that day depends on your lender, escrow, title company and county offices, so confirm early.

Who pays the property tax installment due December 10 if I close in December?

Taxes are normally prorated in escrow, but LA County says the new owner is responsible for any taxes not paid when escrow closes. Ask your escrow officer whether the first installment is being paid through escrow.

Will my impound account pay my supplemental tax bill?

Generally not. LA County says supplemental bills are mailed directly to the owner and are generally not paid from impound accounts. Check with your lender when the bill arrives.

Should I rush to close by December 31 for the tax deduction?

Only if you itemize and your tax preparer says it matters. Deductible interest, property tax and points paid at closing only help if you itemize instead of taking the standard deduction.
