Year-End Homeowner Tax Checklist 2026: 8 Moves Before December 31
Two months left to shrink your 2026 tax bill. Paying the January mortgage early, bunching under the new $40K SALT cap, capturing purchase points — here are the moves that only work before the calendar flips.
Year-End Homeowner Tax Moves 2026: Before Dec 31 Deadline
Top year-end homeowner tax moves for 2026: (1) Pay the January 2027 mortgage payment by December 31 to pull ~$1,500–$2,500 of interest into 2026 — only if itemizing. (2) The SALT cap is $40,000 for 2026 — bunch property-tax installments under it. (3) Points paid on a 2026 purchase are fully deductible this year; refi points amortize. (4) Batch charitable gifts in a bunching year. (5) Verify PMI deduction reinstatement before filing. The 2026 standard deduction (~$32,200 MFJ) is the gate — itemizing only wins above it.

The 8-Move Checklist (Ranked by Effort → Impact)
Every move below must happen before December 31, 2026 to count on your 2026 return.
| # | Move | Value | Effort |
|---|---|---|---|
| 1 | Run itemize vs. standard first If your total deductions don't beat ~$32,200 (MFJ), skip every move below — you're taking the standard deduction anyway. | Everything depends on it | 10 min |
| 2 | Pay the January payment in December Interest is deducted when paid. Paying before Dec 31 pulls ~$1,500–$2,500 of deductible interest into 2026. | +1 month interest | Easy |
| 3 | Bunch property tax under $40K SALT Prepay spring installments while under the cap — worthless if you're already over $40K or taking standard. | Up to $40K deduction | Easy |
| 4 | Close a purchase before Dec 31 Purchase points are fully deductible the year paid; refi points are spread over the loan life. | Points + interest now | Timing |
| 5 | Batch charitable gifts Moving 2027 donations into a bunching year can push you over the standard deduction. | Clears the hurdle | Easy |
| 6 | Verify PMI/MIP deduction status May be reinstated for 2026 — check IRS Pub 936 in January before filing. | Possible bonus | 5 min |
| 7 | Confirm energy credit eligibility IRA 25C/25D credits ended for installs after Dec 31, 2025. 2026 projects generally don't qualify — don't count them. | Verify — most ended | 10 min |
| 8 | Grab your 1098 + escrow records Download your mortgage interest statement + year-end escrow analysis in early January. | Faster filing | 5 min |
Bunching Deductions: The Strategy Most Homeowners Miss
The standard deduction created a problem: most homeowners don't deduct their mortgage interest at all because their total deductions fall just under the threshold. Bunching fixes it — you jam two years of deductible spending into one year, itemize big that year, then take the standard deduction the next.
| Example: Couple, $28K Interest + $12K SALT/yr | 2026 | 2027 | Total |
|---|---|---|---|
| No bunching (itemize both yrs) | $40K deducted | $40K deducted | $80K |
| Bunching (itemize / standard) | $52K deducted* | $32.2K standard | $84.2K |
*Early January payment + prepaid spring property-tax + bunched charity adds ~$12K to 2026. Result: $4,200 more deductions = ~$1,000 saved at a 24% bracket. The bigger your gap from the standard deduction, the more bunching pays.
Why 2026 Is Different: The $40K SALT Cap Changes the Math
For 2018–2025, the $10,000 SALT cap made property-tax prepayment pointless — most homeowners hit it instantly. For 2026 the cap jumped to $40,000 (with a phase-down above ~$500K income), which revives prepayment as a real lever: paying the spring installment in December adds a full deduction this year.
✓ Prepay makes sense if…
Your total state + property + income/sales tax is under $40K and you're itemizing 2026. Every prepaid dollar deducts now.
✗ Skip it if…
You're already over the cap, taking the standard deduction, or your income puts you in the phase-down zone (~$500K+ MAGI).

A December 2026 closing captures deductions this year that a January 2027 closing pushes out 12 months:
- →Points paid at purchase — deductible in full in the year paid (refi points must amortize over the loan term).
- →Prepaid interest at closing — the per-diem interest on your Closing Disclosure is deductible in 2026.
- →Property tax you reimburse the seller — counts toward your $40K SALT bucket for 2026.

Frequently Asked Questions: Year-End Tax Moves 2026
What can homeowners deduct before the end of 2026?▼
For tax year 2026 (filed in 2027), itemizing homeowners can deduct: mortgage interest on up to $750,000 of acquisition debt ($375,000 married filing separately), property taxes + state income/sales taxes up to the $40,000 SALT cap (raised from $10K for 2026), mortgage points paid at closing, and PMI/mortgage insurance premiums if Congress reinstates the deduction for 2026. The standard deduction for 2026 is roughly $32,200 married filing jointly — itemizing only wins when your deductions exceed that.Run my numbers →
Does paying my January 2027 mortgage in December help my taxes?▼
Sometimes. Mortgage interest is deductible in the year PAID, not accrued. If you pay your January 2027 payment before December 31, 2026, that payment's interest portion counts toward your 2026 deductions. This works only if you're itemizing in 2026 AND it pushes you over the standard deduction threshold. Warning: it also means you have one fewer deductible payment in 2027 — this is a bunching strategy, so only do it in years you plan to itemize.Run my numbers →
What is bunching deductions and does it still work in 2026?▼
Bunching means concentrating two years of deductions into one tax year, then taking the standard deduction the next. With the 2026 SALT cap at $40,000, bunching is less powerful than in the $10K-cap era, but it still works for homeowners near the itemizing threshold: prepay January mortgage interest, prepay spring property-tax installments, and batch charitable donations into one year. Example: a couple with $31K in annual deductions gains ~$1,200 by bunching to $40K+ one year and taking the $32,200 standard deduction the next.Run my numbers →
Is PMI tax deductible in 2026?▼
The mortgage insurance premium deduction (PMI, FHA MIP, VA funding fee, USDA guarantee fee) has been on-again/off-again — it was allowed through 2021, expired, and its 2026 status depends on Congressional action. If reinstated, it phases out starting at $100,000 AGI ($50,000 MFS). Check the IRS Pub 936 update in January 2027 before filing; if it passes late in 2026, you may deduct premiums you paid all year. Don't count on it when planning — treat it as a bonus.Run my numbers →
Are there tax credits expiring December 31, 2026?▼
Watch three deadlines: (1) Any remaining home energy credits — the IRA 25C/25D credits ended for property placed in service after Dec 31, 2025, so 2026 installations generally don't qualify (verify your specific project). (2) Points paid on a 2026 refinance must be deducted over the loan life, but points on a 2026 PURCHASE are fully deductible in 2026 — closing before Dec 31 captures them this year. (3) If you bought in 2026, filing to deduct eligible closing costs requires owning before year-end — a January 2027 closing shifts those deductions to 2027.Run my numbers →
Should I itemize or take the standard deduction in 2026?▼
Take whichever is bigger. 2026 standard deduction: roughly $32,200 MFJ, $16,100 single, $24,150 head of household. Itemizing wins when mortgage interest + SALT (up to $40K) + charity + medical (over 7.5% AGI) exceeds it. Typical breakpoint: a homeowner with a $400K+ mortgage at ~6.5% pays ~$26K interest — add $10K+ SALT and you're over the standard deduction. Below a ~$300K mortgage at today's rates, the standard deduction usually wins unless you have large charitable or medical deductions.Run my numbers →
