Do you know how much you will have to pay in taxes this year? Or do you know what new regulations have been introduced by the IRS that will affect your taxes in 2025? Between inflation, shifting income thresholds and the possible inclusion of several tax reforms, 2025 is a year of huge tax law changes in the U.S. Whether you're a private taxpayer or a small business owner or even if you’re planning for retirement, being informed is essential.
That is where tax preparation services can be useful, helping you to stay away from penalties and make the most of new deductions, exemptions and planning tools.
Let us now explore the most significant tax law updates and regulatory changes to understand about in 2025.
1. IRS Adjusts Federal Income Tax Brackets for Inflation
Each year, the IRS changes Tax Brackets by more or less 2.8%—for 2025. Although the seven federal taxes (10% to 37%) remain unchanged, the income ranges for every bracket have moved somewhat.
Here’s how the 2025 tax brackets look:
|
Tax Rate |
Single Filers |
Married Filing Jointly |
Heads of Household |
|
10% |
$0 – $11,925 |
$0 – $23,850 |
$0 – $17,000 |
|
12% |
$11,926 – $48,475 |
$23,851 – $96,950 |
$17,001 – $64,850 |
|
22% |
$48,476 – $103,350 |
$96,951 – $206,700 |
$64,851 – $103,350 |
|
24% |
$103,351 – $197,300 |
$206,701 – $394,600 |
$103,351 – $197,300 |
|
32% |
$197,301 – $250,525 |
$394,601 – $501,050 |
$197,301 – $250,500 |
|
35% |
$250,526 – $626,350 |
$501,051 – $751,600 |
$250,501 – $626,350 |
|
37% |
$626,351+ |
$751,601+ |
$626,351+ |
These changes may help reduce your tax bill slightly or at least prevent you from jumping into a higher bracket just because of cost-of-living wage hikes.
2. Higher Standard Deductions
The standard deduction, i.e. how much you owe on income tax without needing to itemize, is also increasing for 2025:
- Single filers: USD 15,000
- Married couples filing jointly: USD 30,000
- Heads of household: USD 22,500
- Over 65 and blind, you get an extra USD 2,000 (single) or USD 1,600 (married filing together)
Why is this important? Greater deductions mean much less of your income is taxed, which is an additional reason to reconsider your tax preparation this season.
3. Capital Gains
Capital gains from selling stocks, real estate, or investments held over a year are taxable differently than normal income. In 2025, the capital gains tax thresholds also received a bump:
|
Tax Rate |
Single Filers |
Married Filing Jointly |
Head of Household |
|
0% |
$0 – $48,350 |
$0 – $96,700 |
$0 – $64,750 |
|
15% |
$48,351 – $533,400 |
$96,701 – $600,050 |
$64,751 – $566,700 |
|
20% |
Over $533,400 |
Over $600,050 |
Over $566,700 |
If you fall in the 0% bracket, you could pay no tax on long-term capital gains. For many families, this means strategic timing of asset sales can make a big difference.
4. Changes to the Alternative Minimum Tax (AMT)
The AMT was established to ensure high earners pay at least some tax. But exemptions in recent years have impacted fewer individuals.
In 2025:
- AMT Exemption (single): USD 88,100
- AMT Exemption (married): USD 137,300
- Phase-out begins at: USD 626,350 (single) / USD 1,252,700 (married)
In case you're near these limits, question your tax professional. Tax preparation services can calculate your AMT exposure and also save you surprises.
5. Retirement Plan Contribution Updates
Getting prepared for retirement? These 2025 updates save you more:
- 401(k), 403(b) & 457 plans: Contribution limit is USD 23,500
- IRA (Traditional & Roth): Contributions limit USD 7,000
- Catch-up contributions (age 50+): USD 1,000 for IRAs; 401(k) plans: USD 7,500
- NEW Catch-up for 60–63-year-olds: Up to USD 11,250 in 401(k) plans
- SIMPLE IRA: Limit USD 16,500; Additional USD 3,500 catch-up for 50+; USD 5,250 if 60–63 years old
These changes leave older Americans more time to catch up on retirement savings.
6. Child Tax Credit Updates
The maximum Child Tax Credit remains USD 2,000 per eligible child, however the refundable amount is USD 1,700, which means much more low-income households might receive a tax refund.
This particular credit isn't indexed for inflation and may lose value in case new laws are introduced.
7. Gift & Estate Tax Changes
For 2025 the numbers look like this:
- Annual gift tax exclusion: USD 19,000 per person (up from USD 18,000)
- Exemption for estate taxes per person: USD 13.99 million
For families with generational wealth or high-value estates these are big changes. But wait—the estate tax exemption might decrease significantly in 2026 when the TCJA expires.
8. What Might Change if the TCJA Expires After 2025?
The 2017 Tax Cuts & Jobs Act (TCJA) provided many temporary tax reforms. Unless Congress acts, these expire at the end of 2025. What could change:
- Individual tax rates could increase
- Standard deductions could be slashed
- Personal exemptions could return
- SALT deduction cap may be lifted
- Estate and gift tax exemptions may be halved
In case you have a huge present coming up, a trust or a change in filing status, 2025 is your last opportunity to benefit from existing rules.
9. Corporate and Small Business Tax Updates
If you run a business, these corporate tax law updates matter:
- Unless Congress alters the rule, Section 174 requires R&D costs be capitalized over 5 years (not immediately deducted)
- Bonus depreciation falls to 60% for qualified assets from 100%
- Interest deduction limits might tighten under IRS tax law updates
Smaller businesses that prepare taxes should discuss just how these affect operating costs and deductions.
10. Regulatory Focus: IRS Enforcement & AI Use
In 2025, the IRS also is introducing new enforcement technologies, including AI and machine learning to catch tax fraud and underreporting. Increased IRS funding might mean more audits—particularly for:
- High earners
- Crypto investors
- Gig economy workers
- Businesses with complicated deductions
And keeping clean, documented financials is more important than ever, something tax preparation services specialize in.
