What Changed With the SALT Deduction in 2026?
Quick Answer: For 2026, the SALT deduction cap jumped to $40,000. That is a big change from the old $10,000 TCJA limit. However, a new income phaseout limits the benefit for wealthy clients.
The state and local tax (SALT) deduction lets clients deduct state income, property, and sales taxes on Schedule A. For years, the Tax Cuts and Jobs Act capped this at $10,000. As a result, most high earners in high-tax states lost real value. Now the rules have shifted again.
The One Big Beautiful Bill Act (OBBBA), signed on July 4, 2025, raised the cap to $40,000 for 2026. Therefore, many clients can suddenly deduct four times more. However, the law added a phaseout tied to income. Learning how to advise clients on SALT deduction limitations means mastering both the higher cap and its new limits.
The New $40,000 Cap Explained
The $40,000 cap applies to combined state and local taxes. Married couples filing jointly share one cap, not two. Consequently, a couple in New York or California may still hit the ceiling quickly. Property tax alone can exhaust the limit for many homeowners.
You can review the official rules on the IRS topic page for deductible taxes. Furthermore, proactive tax strategy planning for 2026 helps clients time payments to maximize the deduction.
Who Benefits Most From the Higher Cap?
Upper-middle-income clients gain the most. For example, a household earning $300,000 with high property taxes now deducts far more. Meanwhile, ultra-high earners see the benefit shrink due to the phaseout. As a result, your advice must fit each income band.
Pro Tip: Segment your client list by MAGI first. Then map who wins under the $40,000 cap versus who faces the phaseout.
How Do You Calculate the 2026 SALT Cap Phaseout?
Quick Answer: The phaseout begins when MAGI passes $500,000. The cap drops by 30% of the excess income. However, it never falls below a $10,000 floor.
The phaseout is the trickiest part of the 2026 rules. When a client’s modified adjusted gross income (MAGI) tops $500,000, the $40,000 cap starts shrinking. Specifically, it reduces by 30 cents for each dollar above $500,000. Nevertheless, the cap never drops below $10,000, matching the old TCJA limit.
A Step-by-Step Calculation
Consider a client with $600,000 MAGI. First, subtract the threshold: $600,000 minus $500,000 equals $100,000. Next, multiply by 30%: that gives $30,000. Then subtract from the cap: $40,000 minus $30,000 leaves a $10,000 SALT deduction. So this client hits the floor immediately.
Modeling these numbers by hand wastes billable time. Instead, use our SALT deduction strategy calculator to run scenarios fast. As a result, you can show clients exact outcomes during a review call.
2026 Phaseout Reference Table
| Client MAGI | Excess Over $500K | Cap Reduction (30%) | Allowed SALT Cap |
|---|---|---|---|
| $450,000 | $0 | $0 | $40,000 |
| $550,000 | $50,000 | $15,000 | $25,000 |
| $600,000 | $100,000 | $30,000 | $10,000 (floor) |
| $750,000 | $250,000 | $75,000 | $10,000 (floor) |
Did You Know? Clients between $500,000 and $633,333 MAGI face the steepest marginal loss. Above that, the $10,000 floor holds steady.
How Does the PTET Workaround Beat the SALT Cap?
Quick Answer: The pass-through entity tax (PTET) shifts the state tax deduction to the business return. Therefore, it bypasses the individual SALT cap entirely for many owners.
The PTET is a state-level election. It lets a partnership or S corporation pay state income tax at the entity level. The business then deducts that tax fully on its federal return. As a result, the owner sidesteps the personal SALT cap. More than 35 states now offer some form of PTET.
Why PTET Still Matters in 2026
Even with the higher $40,000 cap, PTET remains powerful. High earners facing the phaseout lose most of their personal deduction. However, the PTET deduction has no federal cap. Consequently, a business owner in a high-tax state can save far more through the entity election.
This is where smart entity structuring for owners pays off. For instance, converting a sole proprietorship to an S corporation may unlock PTET benefits. The IRS blessed these state workarounds in Notice 2020-75, and they remain valid.
A Real PTET Example
Imagine a consultant earning $700,000 through an S corp in a state with a 6% income tax. Her state tax runs about $42,000. Personally, her SALT cap sits at the $10,000 floor. However, with PTET, the entity deducts the full $42,000 federally. That saves roughly $11,800 in federal tax at a 37% bracket.
Pro Tip: Confirm each state’s PTET election deadline. Some require estimated payments during the tax year, not after.
Why Must You Run a State Conformity Review First?
Quick Answer: States do not all follow federal rules. Therefore, you must confirm each state’s conformity before showing after-tax projections to any client.
State conformity means whether a state adopts the federal tax code. Some states conform automatically. Others use a fixed date. A few decouple entirely from federal changes. For example, Florida recently decoupled from certain 2025 federal corporate tax breaks. As a result, federal-only projections can mislead your clients.
This risk grows for high-net-worth clients with multistate income. If you advise high-net-worth individuals and families, a conformity review is non-negotiable. Furthermore, trusts and pass-throughs add layers of complexity across state lines.
Your State Conformity Checklist
- Does the state conform to the federal SALT and OBBBA changes?
- Does it use rolling or fixed-date conformity?
- Does it offer a PTET election, and by what deadline?
- Does it require addbacks for federal deductions?
- Are nonresident-source gains taxed differently?
Multistate Client Scenario
Consider a client living in Texas but earning rental income in New Jersey. Texas has no income tax. However, New Jersey taxes that nonresident rental income. Therefore, the SALT analysis must cover both states. Missing this step could trigger a surprise state bill. You can verify state rules at the Federation of Tax Administrators state agency directory.
Should Your Client Itemize or Take the Standard Deduction?
Compare total itemized deductions against the 2026 standard deduction. Itemize only when the total is larger. Otherwise, the standard deduction wins.
The higher SALT cap makes itemizing worthwhile for more clients. Still, you must compare against the 2026 standard deduction. For 2026, the standard deduction is $16,100 for single filers. Married couples filing jointly get $32,200. Therefore, the SALT deduction only helps when itemized totals beat these numbers.
2026 Standard Deduction Comparison
| Filing Status | 2026 Standard Deduction | Itemize If SALT + Other Exceeds |
|---|---|---|
| Single | $16,100 | $16,100 |
| Married Filing Jointly | $32,200 | $32,200 |
You can confirm these figures on the IRS 2026 inflation adjustment page. Verify current limits at IRS.gov before filing season.
Bunching Strategy for 2026
Some clients hover near the threshold. In these cases, suggest bunching deductions. For example, prepay property taxes or stack charitable gifts in one year. As a result, the client itemizes in that year and takes the standard deduction the next. This timing move can add real savings.
How Do You Package SALT Advice as Premium Advisory?
Quick Answer: Turn SALT analysis into a paid planning engagement. Charge for the multistate conformity review and PTET modeling, not just the return.
Solo practitioners often give this work away for free. That is a costly mistake. A full SALT and PTET analysis takes real expertise. Therefore, you should charge for it as advisory work. Clients happily pay for clear savings and peace of mind. This shift moves you from tax prep to ongoing tax advisory relationships. To go deeper, learn how the Uncle Kam marketplace helps tax pros transition to advisory with AI software, MERNA certification, and warm leads.
The biggest friction for solo pros is time and tooling. Running unlimited scenarios by hand does not scale. That is why tax planning software with unlimited assessments matters. You can run a client-ready SALT and PTET assessment on every prospect before they sign. As a result, you prove value first and close more advisory work. Our SALT deduction advisory toolkit gives your clients clear, branded scenarios.

Uncle Kam in Action: The Solo Practitioner Who Doubled Her Advisory Revenue
Client Snapshot: Dana is a 44-year-old solo CPA running a small firm. She serves 60 clients, many with multistate income and high property taxes. She wore every hat and had no leverage.
Financial Profile: Her firm earned about $220,000 in annual revenue. Most of that came from tax prep, not advisory. Her margins were thin.
The Challenge: Dana’s high-net-worth clients faced the new 2026 SALT phaseout. Several earned over $600,000 in MAGI. As a result, their SALT deduction dropped to the $10,000 floor. They wanted answers, and they wanted them fast. However, Dana lacked a system to model PTET workarounds across states.
The Uncle Kam Solution: Dana used the MERNA framework to restructure her top clients. First, she ran unlimited SALT and PTET assessments on every high earner. Next, she moved three consulting clients to S corporations with PTET elections. Then she built branded planning deliverables for each one. Consequently, she charged for the analysis as a premium advisory service.
The Results: For one $700,000 client, the PTET election saved roughly $11,800 in federal tax. Across her book, Dana delivered over $95,000 in combined client savings. She charged $28,000 in new advisory fees for the SALT and PTET work. Therefore, her first-year return topped 3x on her Uncle Kam investment of about $9,000. Her advisory revenue nearly doubled in one season.

Frequently Asked Questions
What is the 2026 SALT deduction cap?
The 2026 SALT cap is $40,000 under the OBBBA. However, it phases down for MAGI above $500,000. The cap never drops below a $10,000 floor. Verify current limits at IRS.gov before filing.
Can high earners avoid the SALT cap phaseout?
Yes, in many cases. Business owners can use a PTET election. This shifts the state tax deduction to the entity return. Therefore, it bypasses the personal SALT cap entirely for qualifying income.
Why does state conformity matter for SALT advice?
States do not all follow federal rules. Some decouple or use fixed-date conformity. As a result, a federal-only projection can be wrong. Always confirm each relevant state before advising clients.
How does a multistate client change the SALT analysis?
Multistate clients trigger multiple filings. Nonresident income may be taxed in the source state. Therefore, you must review each state’s rules. Missing this can create surprise tax bills and penalties.
Should I charge separately for SALT planning?
Yes. SALT and PTET analysis is skilled advisory work. Therefore, package it as a paid planning engagement. Clients pay for savings and clarity, not for a free tax form add-on.
When should I start SALT planning for clients?
Start well before year-end. PTET elections and bunching moves need action during the tax year. As a result, waiting until filing season removes most planning options.
