2025 IRS Tax Changes Every Filer Should Know

Each year, the IRS updates tax laws to reflect economic conditions, inflation, and legislative changes and 2025 is no exception. Whether you are filing as an individual, a business owner, or are self-employed, it is crucial to understand the changes that could impact your return. This guide covers the most important IRS tax changes for 2025, including updates to tax brackets, the standard deduction, tax credits, retirement contributions, and more.

2025 Federal Income Tax Brackets (Inflation-Adjusted)

The IRS adjusts federal income tax brackets annually based on inflation. These changes are designed to prevent “bracket creep,” where taxpayers are pushed into higher brackets even if their purchasing power hasn’t increased.

Here are the 2025 tax brackets for each filing status:

Single Filers

10%: $0 to $11,275
12%: $11,276 to $45,900
22%: $45,901 to $99,850
24%: $99,851 to $183,000
32%: $183,001 to $228,800
35%: $228,801 to $578,150
37%: Over $578,150

Married Filing Jointly

10%: $0 to $22,550
12%: $22,551 to $91,800
22%: $91,801 to $199,700
24%: $199,701 to $366,000
32%: $366,001 to $457,600
35%: $457,601 to $693,750
37%: Over $693,750

These brackets are slightly higher than in 2024, reflecting the rise in the cost of living.

Standard Deduction Increases for 2025

The standard deduction is a flat-dollar reduction from your taxable income — and it’s one of the most significant ways Americans lower their tax bill.

Standard deductions for 2025 are:

Single: $14,600 (up from $13,850 in 2024)
Married Filing Jointly: $29,200 (up from $27,700)
Head of Household: $21,900 (up from $20,800)

If you don’t itemize deductions, you’ll likely claim the standard deduction. These higher amounts help counteract inflation but may affect eligibility for certain tax credits.

Child Tax Credit (CTC) and Earned Income Tax Credit (EITC)

There’s no permanent legislation (as of July 2025) expanding the Child Tax Credit, but the base rules remain in place unless Congress acts later in the year.

Child Tax Credit (CTC) – 2025

$2,000 per qualifying child (up to $1,600 is refundable)
Phase-out begins at $200,000 (single) / $400,000 (married filing jointly)

Earned Income Tax Credit (EITC) – 2025

EITC remains available for low- and moderate-income workers. Maximum credit amounts vary based on the number of children:

No children: up to $632
One child: up to $4,215
Two children: up to $6,983
Three or more children: up to $7,830

To claim EITC, your income must fall below IRS thresholds, which are adjusted each year.

Tax Changes for Self-Employed Filers

Freelancers, gig workers, and small business owners should take note of the following:

1. Self-Employment Tax Rate

The combined Social Security and Medicare tax remains at 15.3%:

12.4% for Social Security
2.9% for Medicare
An additional 0.9% Medicare surtax may apply for high earners (over $200,000 single / $250,000 joint).

2. Qualified Business Income (QBI) Deduction

The 20% QBI deduction for pass-through entities (sole proprietors, S-corps, partnerships) is still available for most, but income limits affect eligibility. Keep records organized and ensure your business qualifies.

3. Mileage Rate for 2025

The IRS mileage reimbursement rate for business use is 67 cents per mile — up from 65.5 cents in 2024. This can make a big difference if you drive often for work.

Health Insurance Penalty & Premium Tax Credit

There is no federal tax penalty for not having health insurance in 2025, but some states (like California, New Jersey, and Massachusetts) still enforce their own.

If you purchase health coverage through the Marketplace (HealthCare.gov) and receive a subsidy, be sure to report income changes throughout the year to avoid repayment issues during tax time.

The Premium Tax Credit (PTC) remains available and expanded under current legislation, but that may change in future years.

Retirement Contributions

Good news for retirement savers! Contribution limits have increased for 2025:

401(k), 403(b), and most 457 plans:
$23,000 (up from $22,500)
- $7,500 catch-up for age 50+
Traditional and Roth IRAs:
$7,000 (up from $6,500)
- $1,000 catch-up for age 50+

These higher limits let you shelter more income from taxes, either now (traditional) or in the future (Roth).

Homeowners and Mortgage Interest Deduction

For most filers, the standard deduction is still more beneficial than itemizing, but those with large mortgages or high property taxes may still benefit from itemizing deductions.

In 2025:

Mortgage interest deduction applies up to $750,000 of loan principal.
Property tax deduction (combined with state income taxes) remains capped at $10,000 under SALT rules.

Changes to Tax Forms

Here are a few form updates to watch for:

Form 1040 has minor layout changes and additional lines for digital asset reporting.
1099-K thresholds remain controversial and are addressed in a separate blog post.
Form 8862 is increasingly required if you’ve had past EITC or ACTC disallowances.

Digital asset (crypto) reporting now appears as a yes/no checkbox on Form 1040 — answer honestly, even if you only used a crypto wallet.

Tax Tip: Adjust Withholding or Make Estimated Payments

f your income changed significantly in 2025 (due to a raise, side business, marriage, or home sale), update your W-4 with your employer or start making quarterly estimated payments using Form 1040-ES.

Failure to pay enough tax throughout the year can result in underpayment penalties, even if you receive a refund later.

Key Filing Dates for the 2025 Tax Season

January 31, 2026: Deadline for employers to send W-2s and 1099s
April 15, 2026: Tax filing deadline (unless extended)
October 15, 2026: Extended deadline for those who file Form 4868

Start early, especially if you’re claiming credits or have multiple income sources.
