Understanding the SALT Deduction

The SALT deduction permits taxpayers who itemize their deductions to subtract specific state and local taxes from their federal taxable income. Eligible taxes include state and local income taxes, property taxes, and either sales taxes or income taxes—but not both. This deduction is claimed on Schedule A of Form 1040.

Key Takeaways

• The SALT deduction allows taxpayers to deduct certain state and local taxes from their federal taxable income, with a current cap of $10,000.
• Taxpayers must choose between deducting state and local income taxes or state and local sales taxes; understanding which is more beneficial is crucial.
• Utilizing tax calculators, such as those recommended by NACO, can simplify the process of determining the most advantageous deduction method and ensure compliance with IRS guidelines.

The $10,000 Cap

Introduced by the bipartisan Tax Cuts and Jobs Act of 2017, the SALT deduction is capped at $10,000 ($5,000 for married individuals filing separately) through 2025 as part of broader tax reform efforts. This cap limits the total amount of state and local taxes that can be deducted on your federal tax return, potentially increasing your tax bill and affecting any expected refund. Note that this cap applies collectively to all deductible state and local taxes.

Choosing Between Income and Sales Tax Deductions

Taxpayers have the option to deduct either state and local income taxes or state and local sales taxes—but not both. The optimal choice depends on your individual financial situation:

• Income Tax Deduction: If you reside in a state with high income taxes and have substantial income, deducting state and local income taxes may be more beneficial.
• Sales Tax Deduction: If you live in a state with no or low income taxes or made significant purchases subject to sales tax, deducting state and local sales taxes might yield a higher deduction.

The IRS provides a Sales Tax Deduction Calculator to help estimate your deduction based on your location and expenditures.

Utilizing Tax Calculators

Tax calculators are invaluable tools for accurately determining your potential SALT deduction. They assist in comparing the benefits of deducting income taxes versus sales taxes and ensure compliance with IRS regulations.

IRS Sales Tax Deduction Calculator

The IRS offers an online Sales Tax Deduction Calculator that estimates the amount of state and local general sales tax you can claim. To use this tool, you’ll need:

• Filing status
• Number of exemptions
• Adjusted Gross Income (AGI)
• State and local sales tax rates
• Amounts paid for major purchases

By inputting this information, the calculator provides an estimate of your allowable sales tax deduction, helping you decide whether to deduct sales taxes or income taxes.

Practical Steps to Maximize Your SALT Deduction

1. Itemize Deductions: To claim the SALT deduction, you must itemize your deductions on Schedule A of Form 1040. Compare the total of your itemized deductions to the standard deduction to determine which is more advantageous.
2. Maintain Accurate Records: Keep detailed records of all state and local taxes paid, including property taxes, income taxes withheld, estimated tax payments, and receipts for major purchases subject to sales tax.
3. Plan Major Purchases Strategically: If considering significant purchases, such as a vehicle or home improvements, timing them within the same tax year can increase your sales tax deduction.
4. Stay Informed on Legislative Changes: Tax laws are subject to change. Stay updated on NACO’s federal and state tax regulations to ensure you’re maximizing your deductions within the current legal framework.

Frequently Asked Questions

Q: How do I know if I should itemize deductions or take the standard deduction?

A: Compare the total of your itemized deductions, including the SALT deduction, to the standard deduction for your filing status. For tax year 2025, the standard deduction is $15,000 for single filers and $30,000 for married couples filing jointly. If your itemized deductions exceed the standard deduction, itemizing may be the better option.

Q: Can I deduct state and local taxes paid on rental properties?

A: Yes, but not as part of your SALT deduction. State and local property taxes on rental properties are deductible as business expenses on Schedule E, rather than being subject to the $10,000 cap for personal property taxes.

Q: Are there any efforts to remove or increase the SALT deduction cap?

A: Some lawmakers have proposed raising or eliminating the SALT cap, but as of 2025, the $10,000 limit remains in effect. Stay informed on potential legislative changes that could impact future tax filings.
