Overview

Federal tax rules are updated each year to reflect inflation and legislative changes. The most consequential updates for individuals in the recent cycle centered on inflation-indexed tax brackets and thresholds, higher standard deductions, adjustments to tax-preference items (like capital gains thresholds), and increased retirement plan contribution limits. These changes can alter withholding needs, the decision to itemize versus take the standard deduction, and the timing of income or asset sales.

I’ve worked with clients across income levels and seen how relatively small shifts in thresholds change effective tax outcomes. Below I summarize the main changes (with a focus on tax year 2023), explain who is affected, give practical steps you can take now, and point to reliable sources and relevant FinHelp resources.

Quick summary of the most important recent changes (high level)

  • Inflation adjustments to tax brackets and standard deductions for 2023 reduced nominal tax liability for many taxpayers compared with prior years. (IRS announcement on 2023 inflation adjustments.)
  • The standard deduction increased for 2023, pushing more filers toward taking the standard deduction rather than itemizing.
  • Child Tax Credit rules reverted to the pre-2021 structure (generally a $2,000 credit per qualifying child in 2023) with established phase-out thresholds.
  • Retirement account contribution limits (e.g., 401(k) limits) increased for 2023, allowing higher tax-deferred savings.
  • Long-term capital gains tax brackets and thresholds were adjusted for inflation, which affects timing decisions on investment sales.

What changed in detail (2023 highlights you can act on now)

  1. Tax bracket (rate schedule) adjustments
  • The IRS adjusts the income thresholds for the seven ordinary income tax brackets each year for inflation. For 2023 the thresholds moved upward, which can reduce marginal tax rates for taxpayers who remained in the same nominal wage band.
  • Example (selected 2023 thresholds for single filers): 10% bracket up to $11,000; 12% from $11,001 to $44,725. Married filing jointly thresholds are approximately double those single amounts. For the full schedule and official figures, consult the IRS announcement. (IRS, 2023)
  1. Standard deduction increases
  • Standard deduction for 2023: $13,850 (single) and $27,700 (married filing jointly). The higher deduction made the standard deduction the better option for more taxpayers compared with itemizing. (IRS, 2023)
  • If you normally itemize, re-run the math each year. See FinHelp’s guide on deciding whether to itemize: How to Decide Whether to Itemize or Use the Standard Deduction.
  1. Child Tax Credit and other family-related credits
  • For 2023, the Child Tax Credit generally returned to a maximum of $2,000 per qualifying child under age 17, with phase-outs beginning at $200,000 for single filers and $400,000 for married couples filing jointly. Note that certain pandemic-related enhancements in 2021 were temporary. For details on qualifying rules and phaseouts, consult the IRS Child Tax Credit page. (IRS)
  1. Retirement contribution limits
  • Employers’ retirement plan contribution limits were higher for 2023. For example, the elective deferral limit for 401(k), 403(b), most 457 plans, and the Thrift Savings Plan rose to $22,500 in 2023; catch-up contributions for those 50 and older were available in addition to that amount. These increases allow higher tax-deferred saving and are a common planning tool. (IRS retirement plan limits announcement)
  1. Capital gains thresholds
  • Long-term capital gains tax rate brackets are tied to ordinary-income thresholds and were adjusted for inflation. Higher thresholds can allow more taxpayers to qualify for the 0% or 15% long-term capital gains rate when they sell appreciated assets. Review your expected 12-month holding periods and projected taxable income when timing sales.

Who is most affected

  • Lower- and middle-income taxpayers often benefit from inflation-indexed bracket shifts and higher standard deductions because their taxable income drops into lower brackets or they stop itemizing.
  • Families with dependents who rely on the Child Tax Credit should check eligibility and phase-out thresholds.
  • High-income earners and investors remain affected by capital gains bracket changes and by limits on other tax benefits (AMT, SALT cap interactions, etc.).
  • People saving for retirement benefit from higher 401(k) limits; small-business owners who set retirement plans can adjust plan design to take advantage of higher limits.

Practical actions to take now (my recommended checklist)

  • Recalculate withholding: Use the IRS Tax Withholding Estimator or update your W-4 if you expect a materially different tax liability due to bracket or deduction changes. Small changes in brackets can meaningfully affect take-home pay. (IRS Tax Withholding Estimator)

  • Run the itemize vs. standard deduction calculation: Don’t assume the same approach as last year. Use this guide: Standard Deduction vs. Itemized Deductions and consider bunching deductible expenses if your itemized deductions are close to the standard amount.

  • Maximize tax-advantaged retirement accounts: If you can, increase your 401(k) or IRA contributions to the 2023 limits (or the current-year limits) to reduce taxable income today and grow tax-deferred savings.

  • Review capital gains timing: If you expect to sell investments, model your taxable income for the year to determine whether you can access the 0% or 15% long-term capital gains rate. Consider tax-loss harvesting where appropriate.

  • Keep good basis records: Accurate cost basis tracking avoids unexpected gains. This is an area where I see avoidable errors that lead to higher tax bills.

Real-world example (typical client scenarios)

  • Mid-income married couple: With the 2023 standard deduction increase to $27,700, a couple with $12,000 of mortgage interest and $8,000 of state and local taxes likely finds the standard deduction is the better route. In my practice, switching several clients to the standard deduction simplified filing and slightly reduced tax prep costs without raising tax liability.

  • Near-retirement saver: A 52-year-old client increased their 401(k) to the 2023 elective deferral limit of $22,500 and used catch-up contributions. This reduced taxable income for the year and improved retirement readiness.

Common mistakes and misconceptions

  • Assuming the same tax choices as prior years: Annual inflation adjustments mean the comparison should be re-run each year.
  • Ignoring phaseouts: Credits like the Child Tax Credit phase out with income. Small changes in AGI can change eligibility.
  • Poor recordkeeping for investment basis: Not tracking adjusted basis leads to overpaying capital gains tax.

Professional tips (from my experience)

  • Small timing moves can be tax-efficient: shifting a bonus, an IRA conversion, or the timing of a stock sale into a different tax year can affect which bracket or capital gains rate applies. I routinely model multi-year scenarios for clients facing large, one-time income events.

  • Treat withholding as a planning tool: rather than aiming for a zero refund, adjust withholding to smooth cash flow across the year while avoiding underpayment penalties.

  • Coordinate retirement and tax planning: If you expect higher income in future years, consider Roth conversions in years when you fall into a lower bracket. Use the current-year contribution limits to take advantage of tax-deferral.
