H.R. 7561 (Local Infrastructure Tax Cuts Act) rewrites the individual limitation on state and local tax (SALT) deductions and creates a new deductible category called “qualified special assessment taxes.” The bill establishes fixed dollar limitation amounts that vary by filing status, phases out SALT deductibility entirely for taxpayers above specified modified adjusted gross income (MAGI) thresholds, and requires future inflation adjustments.
Separately, the bill allows taxpayers to deduct certain special-assessment levies that fund community infrastructure—transportation, utilities, schools, hospitals, emergency services, dam restoration—so long as the assessment applies to their principal residence and the project is owned by a public entity or a not-for-profit, member-owned utility. The change reshapes incentives for local finance and creates new compliance questions for taxpayers, municipalities, and the IRS.
At a Glance
What It Does
The bill sets fixed national dollar limits on deductible state and local taxes ($10,000 for most taxpayers, $5,000 for married filing separately, $0 for taxpayers above a specified MAGI threshold) and indexes those amounts after 2027. It also inserts a new deduction for qualified special-assessment taxes used to fund defined community infrastructure projects, limited to taxes on a taxpayer’s principal residence.
Who It Affects
Owners of homes inside special-assessment districts, municipalities and subdivision finance offices that levy assessments, not-for-profit member-owned utilities, tax preparers and compliance teams, and higher-income taxpayers whose SALT deduction phases out under the new MAGI thresholds.
Why It Matters
By creating a targeted federal deduction for local infrastructure assessments, the bill can make special-assessment financing more attractive to localities while simultaneously tightening SALT benefits for high-MAGI filers. That combination shifts where and how infrastructure can be funded and raises operational and enforcement issues for tax authorities and local governments.

What This Bill Actually Does
The bill does two separate but connected things to individual income-tax deductions for state and local levies. First, it replaces the SALT limitation with a three-tiered applicable limitation amount: $0 for taxpayers whose modified adjusted gross income exceeds a statutory threshold, $5,000 for married individuals filing separately, and $10,000 for other taxpayers.
It also defines the MAGI measure used for the phaseout, sets statutory threshold dollar amounts tied to filing status, and requires inflation indexing for those numbers beginning after 2027.
Second, the bill creates a new deductible category—"qualified special assessment taxes." Those are taxes imposed by states, possessions, political subdivisions, or D.C. on real property inside a geographic area designated as a special assessment district, when the assessment funds a "community infrastructure" project that directly benefits the assessed property. The bill lists the types of projects that qualify, and it requires that the project be owned either by a public entity or by a not-for-profit, member-owned utility service.Crucially for tax administration, the deduction for qualified special-assessment taxes is limited to assessments paid or accrued with respect to a taxpayer's principal residence and is folded into the same limitation regime the bill establishes for other state and local taxes.
Practically, that means homeowners in assessment districts may be able to deduct those levies up to their applicable limitation amount, but taxpayers above the MAGI thresholds get no deduction. The bill applies to taxable years beginning after December 31, 2026, so preparers, municipalities, and the IRS will need to develop guidance and systems before implementation.
The Five Things You Need to Know
The bill sets the "applicable limitation amount" for SALT at $10,000 for most taxpayers, $5,000 for married filing separately, and $0 for taxpayers whose MAGI exceeds a statutory threshold.
Statutory MAGI thresholds that trigger a $0 SALT deduction are $215,000 for joint returns, $161,250 for head-of-household, and $107,500 for other filers; the statute specifies an inflation-adjustment mechanism beginning after 2027.
Adds a new deductible category—"qualified special assessment taxes"—limited to assessments on a taxpayer’s principal residence that fund defined "community infrastructure" projects (transportation, schools, utilities, hospitals, dam restoration, emergency services, etc.).
Requires that qualifying community infrastructure be owned by a State, possession, political subdivision, the District of Columbia, or a not-for-profit member-owned utility; private ownership or developer ownership is excluded.
All changes take effect for taxable years beginning after December 31, 2026, and the special-assessment deduction is explicitly made subject to the bill’s SALT limitation rules.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title — Local Infrastructure Tax Cuts Act
This single-line provision supplies the bill’s public name. It carries no tax rule beyond labeling the act for cross-reference in regulations, guidance, and budget documents.
New MAGI-based limitation framework for SALT deductions
Section 2 replaces the existing internal reference for the SALT limitation with a statutory definition that (1) fixes dollar limitation amounts by filing status, (2) makes those amounts subject to a MAGI-triggered phaseout to zero, (3) defines modified adjusted gross income for purposes of that phaseout, and (4) adds statutory indexing after 2027. From an operational standpoint, tax software and preparers must apply both the filing-status cap and the MAGI test in sequence; the bill’s definition of MAGI increases adjusted gross income by amounts excluded under sections 911, 931, and 933, which matters for U.S. citizens with certain foreign-earned income or possessions-source income.
Creation and definition of 'qualified special assessment taxes'
This section inserts a new paragraph into §164(a) to allow a deduction for qualified special-assessment taxes and then defines that term in §164(b). The definition restricts the deduction to (i) assessments imposed by public entities or D.C., (ii) assessments on real property inside a designated special-assessment district, and (iii) assessments used to fund enumerated community-infrastructure projects. Notably, the bill requires that the project be owned by a qualifying public or not-for-profit member-owned utility entity—excluding private developers—and limits the deduction to assessments on principal residences. The bill also amends cross-references so that the new deduction is governed by the same limitation regime set out in Section 2.
Effective date
All of the Section 3 changes and the revised SALT limitation apply to taxable years beginning after December 31, 2026. That creates a single implementation date for reporting and withholding changes and gives state and local officials a short window to adjust assessment practices and communications to taxpayers.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Homeowners inside special-assessment districts paying assessments on a principal residence — They can deduct qualifying special-assessment taxes (subject to the bill’s limitation), lowering federal taxable income for owner-occupied properties assessed for infrastructure.
- Local governments and special-assessment districts — The federal tax deduction improves the attractiveness of assessment-financed projects to affected homeowners, potentially reducing local political resistance to using assessments for infrastructure funding.
- Not-for-profit, member-owned utilities — Where they own qualifying projects, these utilities enable assessments that are deductible for homeowners, which can support community-led utility upgrades without exposing the entity to corporate tax changes.
Who Bears the Cost
- High-MAGI taxpayers above the statutory thresholds — The bill phases their SALT deduction to $0, removing state and local tax benefits for higher-income filers and effectively increasing federal tax liabilities for those taxpayers compared with a regime that allowed SALT deductions.
- Municipal finance and assessment offices — They will face additional demand for clear documentation and possibly certification that an assessment funds a qualifying community infrastructure project and that the assessed area meets the statutory definition, increasing administrative workload.
- IRS and tax preparers — The agency must issue guidance and establish audit rules to determine whether an assessment ‘‘directly benefits’’ property, whether a project is owned by a qualifying entity, and how to allocate assessments when mixed-use or investment properties are present, adding complexity to enforcement and compliance.
Key Issues
The Core Tension
The central dilemma is whether to use the federal tax code to encourage locally financed infrastructure by making special-assessment levies deductible for homeowners while simultaneously tightening SALT benefits for high-income filers; the approach promotes local project financing but risks unequal benefits, administrative complexity, and loopholes as municipalities and taxpayers respond to new incentives.
The bill's operational details leave room for significant interpretive and implementation challenges. "Directly benefit" is central to whether a special-assessment levy qualifies, but the statute does not provide objective tests or safe harbors for measuring direct benefit; absent IRS regulations, disputes between taxpayers and assessing authorities or between taxpayers and the IRS are likely. The ownership requirement—limiting qualifying projects to public entities or specified non-profits—narrows potential abuse but raises questions about public-private partnership models and projects where private contractors build and operate facilities under long-term leases.
Another tension concerns equity and behavioral responses. By limiting the special-assessment deduction to principal residences, the bill incentivizes owner-occupied financing of local infrastructure but excludes investment properties and commercial parcels; municipalities that rely heavily on commercial assessments may see less federal tax relief for affected owners.
The amendment also creates an enforcement burden: state and local bodies will need standardized documentation and perhaps statutory changes in some states to certify districts and projects in a way the IRS can rely on. Finally, the MAGI phaseout reduces deductibility for higher-income taxpayers, which may alter the political economy of SALT and drive municipalities to favor assessment-based financing over property-tax increases in order to preserve perceived homeowner benefits.
