The “One Big Beautiful Bill” could reshape how much homeowners can write off when filing with the Internal Revenue Service.

Mortgage Interest Deduction May Expand

One of the biggest changes focuses on mortgage interest.

The proposal may:

• Raise deduction limits in high-cost areas

• Adjust how refinancing interest is treated

This could mean larger tax savings for homeowners with bigger loans, especially in expensive markets.

Property Tax Deduction (SALT) Could Increase

Another key update targets state and local tax deductions.

The bill may:

• Increase the current SALT deduction cap

• Allow homeowners to deduct more in property taxes

This is especially important for those in high-tax states where current limits reduce tax breaks.

Energy-Efficient Upgrades Get Bigger Tax Breaks

The proposal also expands incentives for home improvements.

Homeowners may get stronger tax credits for:

• Solar panels

• Insulation upgrades

• Energy-efficient windows and HVAC systems

These credits could lower your tax bill while helping reduce long-term utility costs.

Home Office Deduction May Be Easier

With remote work still common, lawmakers are reviewing home office rules.

Possible changes include:

• Simpler eligibility requirements

• Expanded access beyond self-employed workers

This could open new deductions for more households.

Who Benefits the Most

You may see bigger savings if you:

• Itemize deductions

• Have a large mortgage

• Pay high property taxes

If you use the standard deduction, the impact may be limited unless itemizing becomes more favorable.

Important: The Bill Is Not Final Yet

This proposal is still under review and may change before becoming law.

Experts recommend:

• Avoid making major financial decisions yet

• Wait for final rules before adjusting your tax strategy
