2025 Tax Year Updates Every Taxpayer Should Know

Tax Brackets, Child Tax Credit, and Key Changes

As we prepare for the 2025 tax year, there are several important updates taxpayers should be aware of — especially families and small business owners.

2025 Tax Brackets

The IRS continues to adjust tax brackets for inflation. While the structure remains the same, income thresholds have increased, which may keep some taxpayers in lower brackets compared to prior years. This helps offset inflation but does not eliminate overall tax liability.

How the “One Big Beautiful Bill” Impacts Taxpayers

What Business Owners and Individuals Should Know

The legislation commonly referred to as the “One Big Beautiful Bill builds on prior tax reform efforts with a focus on lower taxes, simplified compliance, and increased take-home pay for individuals and families. While much attention is given to businesses, there are several important implications for individual taxpayers.

Lower Marginal Tax Rates Remain a Priority

One of the core goals of the bill is preserving and extending lower individual income tax rates introduced under prior tax reform. These rates benefit:

  • W-2 employees
  • Retirees with taxable income
  • Households with multiple income sources

For many taxpayers, this means more income taxed at lower rates, especially when combined with inflation-adjusted tax brackets.

Standard Deduction & Simplification

The bill continues to emphasize tax simplification by supporting:

  • A higher standard deduction, reducing the need to itemize
  • Fewer itemized deduction categories
  • Easier filing for households without complex investments or businesses

This benefits individuals who prefer straightforward filing and want to reduce paperwork and audit risk.

Family & Child-Related Benefits

While the bill does not drastically restructure family credits, it reinforces:

  • The Child Tax Credit framework
  • Continued support for working families
  • Policies that reward earned income rather than dependency on itemized deductions

Families may still benefit most from planning income thresholds, especially when phaseouts apply.

Retirement & Savings Focus

For individuals, the bill aligns with policies that:

  • Encourage retirement savings
  • Support tax-advantaged accounts
  • Reduce penalties and barriers for long-term financial planning

This is especially important for middle-income earners balancing retirement, education costs, and household expenses.

What Individual Taxpayers Should Do Now

  • Review withholding and estimated payments
  • Take advantage of standard deduction vs. itemizing comparisons
  • Monitor income thresholds that impact credits and deductions
  • Plan ahead, especially if future legislation sunsets or modifies current provisions

Key Themes of the Bill for Business Owners

  • Continued emphasis on lower marginal tax rates
  • Support for pass-through businesses
  • Reduced regulatory and compliance burdens
  • Encouragement of domestic business investment

What This Means for Business Owner Taxpayers

  • Small business owners may continue to benefit from favorable treatment of pass-through income
  • S corporations and LLCs remain central to tax efficiency strategies
  • Ongoing discussions around making certain tax provisions permanent, rather than temporary

Corporate Tax Transparency

Corporate Tax Transparency

Starting on January 1, 2024, new rules go into effect under the Corporate Transparency Act to prevent anonymous business entity ownership by requiring companies to report their “beneficial owners” to the Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN).

The new regulation does apply to entrepreneurs, small business owners, and larger companies to prevent money launderers, fraud, and others from hiding their identities in “shell companies”. This will affect up to 30 million small businesses, including Single Member LLCs filing a Schedule C.

Major Points about this new act:

  • A beneficial owner is anyone who has substantial control of the company and/or owns or controls at least 25% of the company.
  • Exemptions for the new reporting requirement:
    • Filing is not required if the entity has more than 20 full-time employees, has a physical office in the US, and has filed a tax return with more than $5 million in gross receipts.
  • FinCen will start accepting applications on January 1, 2024.
  • Any entity (business) formed January 1, 2024 or later will have 30 days to file the report.
  • Any entity (business) formed prior to January 1, 2024 must file by January 1, 2025.
  • The report to be filed is called the “Beneficial Ownership Information” (BOI) and this filing will need to be included in the list of things to do when starting and maintaining a business.
  • Failure to file will result in a penalty up to $500 per day, maximum $10,000 and/or up to two years in jail.
  • You may request a unique FinCen Identifier on or after January 1, 2024 prior to filing, when filing, or after filing.
    • If you request a FinCen Identifier after filing, you will need to submit an updated BOI report requesting the FinCen Identifier.
    • If you would like Guiden Tax to prepare your BOI to FinCEN, you will need a unique FinCEN identifier.
  • FinCEN Reporting Website: https://www.fincen.gov/boi
  • FinCEN Reporting Instructions: Beneficial Ownership Information Instructions
