Frequently Asked Questions

Everything you need to know.

Why would I need to do a phase-out review of my SALT amount before entering it into this calculator?
SALT deductions are subject to income-based phase-out rules that reduce your allowable amount as your income rises. The phase-out review determines your actual eligible SALT before applying it to the deduction calculation, since the calculator uses your confirmed post-phase-out figure rather than your total paid amount. If you skip this step, you risk claiming more SALT than the tax law permits.
If my SALT deduction is allowed in full, does that automatically mean my total itemized deductions will be higher than the standard deduction?
Not necessarily. Even with your full eligible SALT amount allowed, you still need to sum all itemizable items (mortgage interest, charitable contributions, medical expenses, and others) to reach your total itemized deductions. You should compare this total against the standard deduction for your filing status to determine which approach saves you more tax. A large SALT deduction doesn't guarantee that itemizing beats taking the standard deduction.
Is the OBBBA Tax Impact Calculator 2026 free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the OBBBA Tax Impact Calculator 2026 affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
