Close by December 31, 2026 — Tax Deduction Snapshot
Buyers who fund before December 31, 2026 can deduct on their 2026 return (filed April 2027): mortgage points ($4,000 per point on a $400K primary-home loan), prepaid per-diem interest from closing to month-end, property-tax proration within the $10K SALT cap, and any 2026 mortgage interest paid. Seller-paid points are deductible by the BUYER — a powerful year-end negotiating tool. Deductions don't vanish if closing slips to January; they shift to the 2027 return filed in 2028, costing ~10 months of refund timing. Itemizing must beat the ~$15K/$30K standard deduction — most closing-year buyers cross it.
Quick Answer: Same Deductions — 10 Months Earlier
Close by Dec 31 and your points, prepaid interest, and property-tax proration hit the 2026 return filed in April — a typical $7K+ deduction worth ~$1,600-$2,400 back by spring. Close in January and the identical deductions wait until April 2028. But don't overpay rush fees chasing the date — run the math first.
What's Deductible on the 2026 Return
Fully deductible year paid — primary home
Per diem interest on the closing disclosure
Counts toward the $10K SALT cap
On a $400K loan at ~7.2%
IRS lets the buyer deduct them — big negotiating lever
NOT deductible — add to cost basis instead
One rule overrides everything: itemizing must beat the standard deduction (~$15K single / ~$30K married for 2026). Closing-year buyers with points + interest usually clear it; renters closing in December often get there on points alone.
The Negotiating Lever Nobody Uses: Seller-Paid Points
The IRS lets the buyer deduct points paid by the seller. In a slow December market where sellers are motivated to close their own year, asking the seller to pay 1-2 points instead of a price cut does double duty: it buys your rate down AND lands as your deduction — real money the seller spends on your behalf.
Example: seller pays $8,000 in points (2 pts on $400K) instead of an $8,000 price cut. You get a ~0.5% lower rate AND an $8,000 deduction worth ~$1,760-$2,400 back in April. The price cut would have saved you ~$50/month; the points save you that AND return cash.

December closings are hard — lenders run skeleton crews, county recorders close early, and title companies back up around the holidays. To hit Dec 31:
- Contract by ~Dec 5-10 for a normal 21-30 day close; faster lenders can fund in ~14 days.
- Watch Dec 9: the Fed's likely hike reprices everything — lock before the meeting if your closing is inside 30 days.
- Target Dec 28-30 funding, not the 31st — recorders and banks effectively close early; a Dec 31 miss costs nothing but timing.
- Don't chase it at any cost: if rush fees or a worse rate exceed ~$2K of refund-timing value, January closing wins.
Frequently Asked Questions
Do refinance closings get the same deductions?
Refi points must be deducted ratably over the loan term (e.g., 1/360th per month on a 30-year) — only purchase loans get the full year-one deduction. Interest paid still counts normally.
Is homeowner's insurance or PMI deductible?
Insurance: no. PMI: the deduction expired after 2021 unless Congress renews it — verify current law at filing. Don't count it in your math.
Where do I see these numbers?
Your Closing Disclosure: Section A (origination/points), prepaid interest line, and property-tax proration. Keep it — you'll hand it to your tax preparer or enter it in software in March-April.
