The One Big Beautiful Bill (OBBB) Act, signed into law in 2025, made several important updates that impact itemized deductions for individuals. Below is a breakdown of the key changes and how they may affect your tax return.<\/p>\n<p><b>State and Local Tax (SALT) Deduction Limit<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>From <b>2025 through 2029<\/b>, the SALT deduction limit increases to <b>$40,000<\/b> ($20,000 if married filing separately).<\/li>\n<li>In <b>2025<\/b>, the limit starts at $40,000 ($20,000 separate). It rises slightly each year by 1% until 2029.<\/li>\n<li>However, the benefit phases out for high-income taxpayers:\n<ul>\n<li>If your modified adjusted gross income (AGI) exceeds <b>$500,000<\/b> ($250,000 if separate), your deduction limit is reduced.<\/li>\n<li>The reduction equals <b>30% of the excess income above the threshold<\/b>, with at least a $10,000 ($5,000 if separate) reduction.<\/li>\n<\/ul>\n<\/li>\n<li>After <b>2029<\/b>, the limit returns to <b>$10,000<\/b> ($5,000 if separate) in 2030.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Home Mortgage Interest Deduction<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>The <b>home mortgage interest deduction<\/b> rules from the Tax Cuts and Jobs Act (TCJA) are made <b>permanent<\/b>.<\/li>\n<li>You can deduct interest on up to <b>$750,000 of acquisition debt<\/b> ($375,000 if married filing separately).<\/li>\n<li>The suspension of interest deductions on <b>home equity debt<\/b> also remains permanent.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Car Loan Interest Deduction<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Typically, personal loan interest is not deductible.<\/li>\n<li>Under the OBBB Act, for <b>2025\u20132028<\/b>, you can deduct up to <b>$10,000 per year<\/b> of interest on loans for U.S.-assembled passenger vehicles.<\/li>\n<li>The deduction phases out for taxpayers with AGI over <b>$100,000<\/b> ($200,000 for joint filers).<\/li>\n<li><b>Important:<\/b> This deduction applies even if you don\u2019t itemize.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Charitable Contribution Deductions<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Starting in <b>2026<\/b>, non-itemizers can deduct up to <b>$1,000<\/b> ($2,000 for joint filers) of cash charitable contributions.<\/li>\n<li>For those who itemize, a new <b>0.5% floor<\/b> applies: your allowable deduction is reduced by 0.5% of your contribution base.<\/li>\n<li>Example: If your contribution base is $100,000, $500 would be subtracted from your allowable deduction.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Personal Casualty and Theft Loss Deduction<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Under the OBBB Act, the rules limiting deductions to <b>federally declared disasters<\/b> are made permanent.<\/li>\n<li>The law expands this to include <b>state-declared disasters<\/b> such as floods, fires, or explosions recognized by a governor.<\/li>\n<li>Losses tied to qualified disasters between <b>2019 and September 2025<\/b> are also covered.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Gambling Losses<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Gambling losses can only offset gambling winnings.<\/li>\n<li>The OBBB Act introduces a new restriction: starting after 2025, only 90% of wagering losses are deductible, and this deduction is limited\u00a0to the amount of gains.<\/li>\n<li>Example: If you win $10,000 and have $12,000 in losses, you can deduct only $9,000.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Moving Expenses<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>The TCJA suspended most moving expense deductions, and the OBBB Act makes this permanent.<\/li>\n<li>Only <b>active-duty military members and intelligence community employees (and their families)<\/b> qualify for moving expense deductions or reimbursements.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><b>Miscellaneous Itemized Deductions<\/b><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>The suspension of miscellaneous itemized deductions (like unreimbursed employee expenses) is now <b>permanent<\/b>.<\/li>\n<li>Exception: Educator expenses are allowed above the line up to <b>$300<\/b> (increasing with inflation).
