SALT Deduction Cap Changes: What Small Businesses Should Know
The state and local tax deduction cap has been a major factor in tax planning since 2018. Here is what small business owners and accountants should underst
The state and local tax (SALT) deduction has been one of the most closely watched tax issues for accountants and small-business owners since the Tax Cuts and Jobs Act of 2017 capped the write-off at $10,000. With ongoing legislative discussions about modifying or lifting that cap, understanding how the SALT deduction interacts with your overall tax strategy is essential for accurate quarterly planning.
How the SALT Cap Affects Pass-Through Entities
The $10,000 cap primarily impacts individual taxpayers who itemize their deductions on Schedule A. For small-business owners operating as sole proprietors, single-member LLCs, or partners in a partnership, business income passes through to their personal returns. This means state and local income taxes generated by business profits are subject to the same SALT limitation as personal property and income taxes.
If your business operates in a high-tax state, the cap can significantly increase your effective tax rate by preventing you from deducting state taxes that were previously fully write-off-eligible.
The Pass-Through Entity Tax Workaround
In response to the federal cap, many states enacted Pass-Through Entity Tax (PTET) elections. By electing PTET, a partnership or S corporation pays state income tax at the entity level rather than passing the tax burden to the owners. Because the business pays the tax, it becomes a deductible business expense on the entity’s federal return, bypassing the individual $10,000 SALT limitation.
If your state offers a PTET election and you operate as an S corp or partnership, this workaround can recover deductions that would otherwise be lost to the cap. Eligibility and the mechanics of the election vary by state, so verifying your local regulations is a necessary first step.
Tracking Tax Payments in QuickBooks
Accurate bookkeeping is critical when navigating complex tax strategies like PTET elections or anticipating changes to the SALT cap. In QuickBooks, ensure that all state tax payments—whether made at the individual level or the entity level—are categorized to dedicated tax liability accounts rather than general expense accounts.
For pass-through entities making estimated state payments under a PTET election, setting up a specific “State Tax Liability” account helps maintain a clear audit trail. This separation ensures that when your accountant prepares your federal return, the entity-level deductions are easily identifiable and correctly reported.
Preparing for Potential Changes
Legislative proposals regarding the SALT cap frequently surface, and any modification to the $10,000 limit would require congressional action. Because tax law changes often come with effective dates that complicate mid-year planning, maintaining clean, up-to-date financial records throughout the year is the best way to adapt quickly. Review your current entity structure and estimated payment strategy with your tax professional to ensure you are positioned to take advantage of whichever deduction rules apply to the current tax year.
