Several 2026 rules shift that math: a higher SALT cap, a new charitable floor, restored mortgage insurance premiums and broader disaster-loss relief.
A note on timing. "2026" here means the tax year, so these returns are generally filed in 2027. The returns filed during 2026 cover tax year 2025 and follow older rules. This article covers the new rules, how to apply them and the mistakes to avoid.
Key Takeaways
- Schedule A reports itemized deductions in place of the standard deduction.
- The 2026 SALT cap rises to $40,400, but a MAGI phase-down can cut it.
- Itemized charity now faces a 0.5% floor, and mortgage insurance premiums return.
- Tips, overtime, car-loan interest and senior deductions go on Schedule 1-A, not Schedule A.
- Confirm every limit against final IRS forms. Some 2026 forms are still drafts.
What Is Schedule A and Who Needs It?
Schedule A attaches to Form 1040 when you itemize personal deductions. Its total reduces taxable income. You compare it with your standard deduction and use the larger one.
The 2026 basic standard deductions, per IRS's 2026 inflation adjustments, are:
| Filing status | Standard deduction |
|---|---|
| Single or married filing separately | $16,100 |
| Head of household | $24,150 |
| Married filing jointly or qualifying surviving spouse | $32,200 |
Age 65 or older, or blind, adds $1,650 per qualification ($2,050 if unmarried and not a surviving spouse).
Schedule A is worth a close look if you are:
- A homeowner with significant mortgage interest
- Paying large state and local taxes
- A substantial charitable donor
- Carrying high unreimbursed medical costs
- Dealing with an eligible casualty loss
Schedule 1-A is a different form
Qualified tips, overtime, car-loan interest and the enhanced senior deduction appear on Schedule 1-A, and the total flows to Form 1040, line 13a. The new non-itemizer charity deduction sits on Form 1040, line 12f. Entering any of these on Schedule A is a common mistake, and it matters because you can claim them without itemizing.
Key 2026 Changes to Schedule A
SALT: higher cap, with a phase-down
For 2026, the cap is $40,400 ($20,200 if married filing separately). The IRS confirmed these figures in its March 2026 correction.
| Filing status | Cap | MAGI threshold | Minimum cap |
|---|---|---|---|
| All except MFS | $40,400 | $505,000 | $10,000 |
| MFS | $20,200 | $252,500 | $5,000 |
The cap shrinks by 30% of MAGI above the threshold, but never below the minimum. SALT MAGI adds back income excluded under sections 911, 931 and 933, which matters for expats. The cap and threshold rise 1% a year through 2029, then revert to $10,000 ($5,000 MFS) in 2030.
Charitable floor
From 2026, itemized contributions count only to the extent they exceed 0.5% of your contribution base, generally AGI. The floor applies to otherwise-eligible gifts, not just cash. The percentage ceilings stay, including 60% for cash.
Amounts lost to the floor don't automatically carry forward. Check Publication 526 before assuming a carryover.
A separate deduction lets non-itemizers claim up to $1,000 ($2,000 MFJ) of qualifying cash gifts. Donor-advised fund contributions generally don't qualify.
The 35% ceiling on benefit
Section 68 returns in 2026. Itemized deductions are reduced by 2/37 of the lesser of your allowable deductions or your taxable income above the start of the 37% bracket. In practice, a deduction exposed to the 37% rate yields at most a 35% benefit. It does not mean only 35% of the expense is deductible.
Mortgage insurance premiums are back
Qualifying premiums are treated as mortgage interest again. The draft Schedule A places them on line 8d, and Form 1098, Box 5 reports them.
- Qualifying types: VA, FHA, Rural Housing Service and private mortgage insurance on contracts issued after 2006
- Property: acquisition debt on a main or second home
- AGI phaseout: starts above $100,000 ($50,000 MFS) and ends above $109,000 ($54,500 MFS)
- Rented second home: personal use must exceed 14 days or 10% of rental days, whichever is greater
Casualty and theft losses
Federal declarations are no longer the only route. Starting in 2026, qualifying state-declared disasters can also support a personal casualty deduction. Ordinary losses follow the usual steps:
- Subtract reimbursements.
- Apply $100 per event.
- Apply the 10%-of-AGI reduction.
- Report on Form 4684, then on draft Schedule A, line 16.
Net qualified disaster losses follow a separate regime: $500 per event, no 10% floor and an election to claim without itemizing. Not every declared disaster qualifies.
Educators, gambling and miscellaneous items
- Educators: The above-the-line limit stays at $350 on Schedule 1. A new itemized category (draft line 17k) removes the dollar cap and widens coverage, including interscholastic sports coaches and administrators.
- Gambling: You deduct the smaller of winnings or 90% of losses (draft line 17a).
- Miscellaneous 2% items: The disallowance is now permanent, with the educator exception.
What did not change
- Medical expenses still need to exceed 7.5% of AGI.
- Mortgage acquisition debt limits stay at $750,000 ($375,000 MFS), with grandfathered $1M limits for older debt.
- HELOC interest still requires proceeds used on the securing home.
- Charitable substantiation rules still apply.
- You still compare itemizing with the standard deduction.
What Can You Deduct on Schedule A in 2026?
Medical and dental expenses
Only unreimbursed qualifying costs above 7.5% of AGI count. Eligible items include medical care, medical insurance premiums and qualified long-term care. General health club dues and HSA contributions don't qualify. Publication 502 has the full list.
Taxes paid
You choose state and local income taxes or general sales taxes, never both. Add qualifying real estate and personal property taxes. The combined total is limited by the SALT cap. The IRS sales tax calculator can help, though actual receipts also work.
Eligible foreign income taxes may be deducted here instead of claimed as a credit. The annual choice covers all eligible foreign taxes, and taxes on income excluded under the foreign earned income exclusion are not deductible.
Interest paid
- Mortgage interest, including points, within the debt limits
- Mortgage insurance premiums (separate line from ordinary interest)
- Investment interest, limited to net investment income and computed on Form 4952
Your lender's Form 1098 supplies most of the numbers.
Charitable contributions
Gifts must go to qualified organizations, not individuals. The documentation triggers differ:
| Trigger | Requirement |
|---|---|
| $250 or more | Written acknowledgment from the charity |
| Noncash over $500 | Form 8283 |
| Noncash over $5,000 per item or group | Generally a qualified appraisal and Form 8283, Section B (publicly traded securities are an exception) |
One receipt doesn't necessarily satisfy all three.
Casualty, theft and other items
Eligible disaster losses, gambling losses and income-producing property losses sit on the lower lines. These are narrow, so use Form 4684 and the current Schedule A instructions rather than guessing.
How the 2026 Changes May Affect Your Tax Return
Comparing standard and itemized deductions
- Total each eligible Schedule A category.
- Apply the floors and caps (medical, charity, SALT, casualty).
- Compare the result with your 2026 standard deduction.
- Carry only the larger permitted amount to Form 1040.
A deduction lowers taxable income, not tax dollar for dollar. The savings depend on which brackets the extra deduction displaces.
Homeowners and high-tax states
The higher SALT cap may help homeowners who previously hit $10,000 quickly. High earners may see the benefit shrink as MAGI passes $505,000. The Congressional Research Service (CRS) notes some filers once constrained by the cap may no longer hit it.
Donors
The 0.5% floor trims smaller gifts. CRS expects a limited effect on giving because most charitable deductions already exceed the floor; that remains a forecast, not a measured 2026 result. Two planning ideas to discuss with a preparer:
- Bunching several years of gifts into one year, so itemizing beats the standard deduction
- Funding a donor-advised fund, which separates the deduction year from later grants
Keep gift acknowledgments either way.
Mortgage insurance
Check lender statements for Box 5 on Form 1098. Eligibility turns on when premiums were paid, your AGI, how the debt was used, and whether the property qualifies.
A hypothetical comparison
These examples use stated assumptions and are not guarantees.
| Scenario | Assumptions | Result |
|---|---|---|
| Homeowner | Single, under 65; AGI $100,000; allowable itemized deductions $20,000; ordinary income only; no credits or AMT | Deduction exceeds the $16,100 standard by $3,900. Both taxable-income amounts stay in the 22% bracket, so regular tax falls about $858 |
| Charitable donor | Contribution base $200,000; eligible gifts $10,000 | The $1,000 floor leaves a $9,000 deduction, before comparing with the standard deduction |
| High-income filer | MFJ; taxable income $1M; itemized deductions $100,000 | Per a CRS Insight, section 68 reduces deductions by about $5,405 and raises tax about $2,000 |
2026 Schedule A Preparation Checklist and Common Mistakes
Pull these records together before you complete Schedule A. 2026 rules differ from prior years, so a full document set reduces rework.

- Form 1098 for mortgage interest and insurance premiums, plus loan records
- Property tax assessments and bills
- State tax withholding and return records, or sales tax receipts
- Medical receipts and reimbursement records
- Charitable acknowledgements, Form 8283 and any appraisals
- Disaster-loss documentation and insurance claims
Common errors to avoid
- Applying 2025 rules to a 2026 return
- Entering Schedule 1-A or line 12f items on Schedule A
- Deducting reimbursed expenses
- Exceeding the SALT cap or ignoring the MAGI phase-down

- Claiming charitable gifts without proper records
- Skipping the standard-versus-itemized comparison
- Using a draft form as if it were final (drafts are not for filing)
If you have business income, cross-border circumstances or multinational interests, your return may need more than a Schedule A check.

Frequently Asked Questions
What is Schedule A on my tax return?
Schedule A reports eligible itemized deductions and attaches to Form 1040. You use it instead of the standard deduction when itemizing gives a larger deduction.
Which taxes are deductible on Schedule A?
State and local income taxes or general sales taxes (not both), plus real estate and personal property taxes. The total is limited by the 2026 SALT cap of $40,400 ($20,200 MFS), subject to phase-down. Confirm current IRS rules before filing.
Do I need to file Schedule A if I take the standard deduction?
No. Generally, you claim either the standard deduction or itemized deductions, not both. If your spouse itemizes on a separate return, your standard deduction is zero, so review that situation with a professional.
Are mortgage insurance premiums deductible on Schedule A for 2026?
Possibly. Eligibility depends on qualifying insurance, a main or second home, AGI between $100,000 and $109,000 for the phaseout, and Form 1098 documentation. Check the current IRS instructions.
How do the 2026 changes affect charitable contributions?
Itemized gifts are deductible only above 0.5% of your contribution base. Percentage limits and substantiation rules continue. Confirm the exact calculation and carryover treatment in Publication 526.
