Overview

Federal tax rules for individual filers change in two ways: legislation (laws passed by Congress) and annual administrative updates (inflation adjustments, IRS guidance). Over the last several years, a mix of temporary pandemic-era legislation, retirement-law reforms, and annual inflation increases has produced the most consequential updates for most taxpayers. This guide highlights the items that matter in practice, explains who is affected, and offers practical steps you can take now.

The biggest changes that matter to individuals

  1. Inflation increases to the standard deduction and tax brackets
  • What changed: The IRS indexes the standard deduction and tax-bracket thresholds to inflation each year. For the 2024 tax year (filing in 2025) the standard deduction rose again — for example, the single filer standard deduction increased to $14,600 (married filing jointly $29,200; head of household $21,900) — reducing taxable income for many taxpayers (IRS annual inflation adjustments). See the IRS standard deduction announcement for the latest year you’re filing.
  • Why it matters: Even modest increases reduce taxable income automatically and can change the decision to itemize versus taking the standard deduction.

  1. Temporary pandemic-era credits mostly expired (Child Tax Credit example)
  • What changed: The American Rescue Plan (2021) temporarily expanded the Child Tax Credit (CTC) for 2021 only. The expanded advance-payment structure and the higher per-child amounts were not extended in the same form. The CTC reverted to its pre-2021 structure (generally up to $2,000 per qualifying child, subject to income phaseouts) after 2021; rules and refundable portions are governed by current statute and IRS guidance (IRS CTC information).
  • Why it matters: Families who received advanced monthly payments in 2021 should be aware that the expansion was exceptional; current year eligibility and amounts follow current IRS rules.

  1. Retirement-plan changes under SECURE 2.0
  • What changed: The SECURE 2.0 Act (enacted late 2022) made several changes that affect individual filers: it raised the minimum required distribution (RMD) age for many taxpayers (moving it above 72 for taxpayers subject to the new rule), expanded catch-up contribution rules for some older savers, and increased options for Roth treatment in certain employer plans. These changes are phased in over several years; some provisions affect plan sponsors first but produce filing consequences for individuals.
  • Why it matters: Changes to RMD ages and catch-up contribution rules affect when you must take taxable distributions and whether contributions are pre-tax or Roth — both of which change taxable income and planning strategies.
  • Source: SECURE Act 2.0 summary (Congress.gov) and IRS retirement plan guidance.
  1. SALT cap and state tax planning remain important
  • What changed: The $10,000 cap on state and local tax (SALT) itemized deductions remains in place for individual filers (originally from the Tax Cuts and Jobs Act of 2017). Several states and localities continue to use workarounds (elective pass-through entity taxes, charitable funds) to mitigate the cap—strategies with important tax and filing consequences.
  • Why it matters: High-state-tax filers still need to plan: a state-level workaround can change the best filing approach and whether paying state-level pass-through entity tax this year reduces federal tax.
  • Source: state tax guidance and analysis from the Tax Policy Center.
  1. Increased IRS funding, compliance, and taxpayer services
  • What changed: Recent federal budget laws and the Inflation Reduction Act allocated more funding to the IRS to modernize systems, hire staff, and improve taxpayer services. That funding also increased compliance activities targeted at higher-income taxpayers and complex returns, while Congress placed limits on certain types of audits for lower-income taxpayers.
  • Why it matters: Expect improved online services but also a higher likelihood of the IRS scrutinizing complex returns. Maintain complete documentation for deductions and credits and consider professional help for complicated returns.
  • Source: IRS news releases and the Inflation Reduction Act summaries.
  1. Limits, phaseouts, and other credit-rule adjustments
  • What changed: Many credits and deductions are adjusted annually for inflation or governed by legislation that can change income phaseouts and eligibility (examples: saver’s credit rules, education-related credits, energy-efficiency credits tied to new programs).
  • Why it matters: Small changes to income thresholds can move a filer in or out of eligibility for credits, so annual review matters.

Practical steps to act on these changes

  • Re-run your taxes annually: Each year’s inflation adjustments, bracket thresholds, and phaseouts change the optimal strategy. If you used itemized deductions in prior years, rerun a comparison to the standard deduction (see our decision guide on When to Itemize Deductions).

  • Track credits and temporary provisions: If you benefited from a temporary credit (for example, pandemic-era provisions), confirm whether the provision expired or requires reconciliation. For instance, families who received Child Tax Credit advances in 2021 had to reconcile those payments with their 2021 return.

  • Review retirement distributions and contributions: Confirm whether your RMD age has changed for your cohort and whether catch-up contribution rules or Roth treatment apply. These affect taxable income and tax planning.

  • Keep better records: With increased IRS resources and targeted compliance, maintain substantiation for deductions—receipts, mileage logs, and formal statements for charitable donations.

  • Use software but validate complex items with a pro: Tax software does a good job for most straightforward returns. For higher-income households, significant life changes (divorce, inheritance, sale of business), or questions about state planning workarounds, get a tax professional involved early.

Real-world examples (anonymized)

  • Example 1: A homeowner with rising mortgage interest and state taxes rechecked itemizing versus the standard deduction after the most recent standard deduction increase. The new standard deduction moved them to the standard deduction this year—saving time and reducing audit exposure.

  • Example 2: A near-retiree recalculated retirement income after SECURE 2.0 raised the RMD age for their cohort. Delaying required withdrawals for a few years reduced taxable income during a low-income year and improved long-term tax efficiency.

Who is most affected

  • Families with children (credits and eligibility rules).
  • Older savers and retirees (RMD and catch-up rules).
  • High-state-tax filers (SALT-related planning).
  • Self-employed and business owners (changes to retirement-plan options and certain credits).

Common mistakes to avoid

  • Assuming temporary credits are permanent. Confirm legislative dates and reconciliation requirements.
  • Forgetting annual inflation adjustments. A higher standard deduction or bracket threshold can change filing choices.
  • Ignoring state-level passthrough or SALT planning opportunities without evaluating federal consequences.
  • Not documenting deductions and credits in case of IRS review.

Quick FAQs

Q: Are 2019–2021 pandemic-related tax changes still in effect?
A: Some pandemic-related measures were temporary (the expanded Child Tax Credit in 2021 was temporary). Other tax provisions that were not expressly extended have reverted to prior law; always check current IRS guidance for the tax year you are filing (IRS CTC page).

Q: Should I change my tax withholding because of these changes?
A: Possibly. If your expected taxable income or credits change materially, update your Form W-4 with your employer or adjust estimated tax payments to avoid underpayment penalties. Consider a mid-year review after major life events.

Q: Will my tax rates change after 2025?
A: Some individual provisions of the Tax Cuts and Jobs Act are scheduled to expire after 2025 unless Congress acts. That creates uncertainty for rates and deductions beyond 2025; keep an eye on Congressional developments and consult a tax advisor for long-range planning.

Final notes from the author

In my 15+ years advising individual filers and small-business owners, I’ve seen small legislative shifts and annual indexation create disproportionate effects on take-home pay and filing choices. The best defense is an annual, documented review of your tax picture—run the numbers, document your decisions, and talk to a professional when returns become complex.
