2025 Tax Updates: Key Tax & Retirement Numbers

The new year brings a fresh wave of tax updates as the IRS adjusts various provisions to account for inflation. These annual changes are designed to protect the value of tax benefits and help taxpayers keep pace with rising costs. By staying informed about these updates, you can fine-tune your financial plans, optimize tax strategies, and take advantage of opportunities to boost your retirement savings in 2025 and beyond.

How the IRS Calculates Annual Tax Adjustments

Each year, the IRS adjusts tax provisions to account for inflation, ensuring that the tax system remains equitable and reflective of economic conditions. Prior to 2018, these adjustments were based on the Consumer Price Index for Urban Consumers (CPI-U), a standard measure of inflation.

However, the Tax Cuts and Jobs Act of 2017 introduced a new benchmark: the Chained Consumer Price Index (C-CPI). Unlike the traditional CPI-U, the C-CPI takes into account changes in consumer behavior, such as substituting less expensive alternatives when prices rise. As a result, the C-CPI typically yields smaller annual adjustments to tax brackets, deductions, and other parameters.

Indeed, these adjustments play a critical role in protecting taxpayers from “bracket creep,” where inflation pushes income into higher tax brackets without an actual increase in purchasing power. By aligning tax thresholds and benefits with the current economic landscape, the IRS ensures the tax system remains fair, helping taxpayers maintain the value of deductions, credits, and income thresholds despite the impact of inflation.

2025 Federal Income Tax Brackets and Rates

The federal income tax system for 2025 maintains its seven-tier structure with rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Additionally, the highest marginal tax rate of 37% will apply to taxable income exceeding $626,350 for single filers and $751,600 for married couples filing jointly.

2025 Standard Deduction Amounts

The 2025 tax adjustments increase standard deduction amounts, offering taxpayers greater opportunities to reduce their taxable income. For single filers, the standard deduction rises to $15,000, while married couples filing jointly can claim $30,000. Meanwhile, heads of household will see their standard deduction increase to $22,500.

Additionally, seniors aged 65 and older benefit from higher deductions. Single filers in this age group can claim an extra $2,000, while those filing jointly are eligible for an additional $1,600 per qualifying spouse.

Alternative Minimum Tax (AMT) Updates for 2025

The Alternative Minimum Tax (AMT) was introduced in the 1960s to ensure high-income taxpayers pay a minimum level of federal income tax, even after leveraging deductions and credits. Designed to curb aggressive tax avoidance strategies, the AMT primarily impacts high earners while generally exempting middle-income taxpayers.

Here are the key AMT updates for 2025:

• Exemption Amounts. Single filers can claim an AMT exemption of $88,100, while married couples filing jointly are eligible for $137,000.
• 28% Rate Threshold. The higher AMT rate of 28% applies to Alternative Minimum Taxable Income (AMTI) exceeding $239,100 for all taxpayers ($119,550 for married couples filing separately).
• Exemption Phaseouts. The AMT exemption begins to phase out at AMTI levels above $626,350 for single filers and $1,252,700 for married couples filing jointly.

Child Tax Credit Updates for 2025

The maximum Child Tax Credit for 2025 remains unchanged at $2,000 per qualifying child, as it is not adjusted annually for inflation. However, the refundable portion of the credit—which enables eligible taxpayers to receive a refund even if they owe no taxes—has been adjusted for inflation, increasing to $1,700 this year.

2025 Capital Gains Tax Brackets

In 2025, the federal capital gains tax rates remain tied to income thresholds, offering opportunities for tax-efficient investment strategies.

• 0% Rate: Taxpayers with total taxable income of $48,350 or less owe no federal capital gains tax.
• 15% Rate: For taxable income between $48,351 and $533,400, long-term capital gains are taxed at 15%.
• 20% Rate: Taxpayers with income exceeding $533,400 are subject to the top capital gains tax rate of 20%.

These brackets apply to long-term capital gains, which are profits from the sale of assets held for more than one year.

Qualified Business Income (QBI) Deduction for 2025

The Qualified Business Income (QBI) deduction, introduced by the Tax Cuts and Jobs Act of 2017, allows eligible pass-through business owners to deduct up to 20% of their qualified business income, providing a valuable tax break.

For the 2025 tax year:

• The phaseout threshold for the QBI deduction begins at $197,300 for individual filers and $394,600 for married couples filing jointly.
• Taxpayers with income above these limits may see their deduction reduced or eliminated, depending on factors such as the type of business and their overall income level.

This deduction is particularly advantageous for small business owners, freelancers, and other pass-through entities, enabling them to lower their effective tax rate.

Annual Gift Tax Exclusion for 2025

In 2025, the annual gift tax exclusion increases to $19,000 per recipient, up from $18,000 in 2024. This means individuals can gift up to $19,000 to any person without triggering gift tax or reducing their lifetime estate and gift tax exemption.

In addition, for gifts to non-U.S. citizen spouses, the exclusion rises to $190,000, an increase from $185,000.

2025 Retirement and Health Savings Account Contribution Limits

The 2025 tax updates bring increased contribution limits for retirement and health savings accounts, reflecting cost-of-living increases. These changes offer taxpayers greater opportunities to grow their retirement savings and set aside funds for healthcare expenses, all while taking advantage of valuable tax benefits.

401(k) and 403(b) Contribution Limits for 2025

In 2025, the annual contribution limit for 401(k) and 403(b) plans increases to $23,500, up from $23,000 in 2024, allowing participants to save even more for retirement.

For taxpayers aged 50 and older, the additional catch-up contribution remains unchanged at $7,500. This means individuals in this age group can contribute up to a total of $31,000 to their retirement accounts in 2025.

New SECURE 2.0 Super 401(k) Catch-Up Contributions for Ages 60-63

Starting in 2025, the SECURE 2.0 Act introduces enhanced catch-up contributions for participants aged 60 to 63, allowing them to supercharge their retirement savings. Eligible individuals can contribute the greater of $10,000 or 150% of the 2024 standard catch-up limit, adjusted annually for inflation.

For the 2025 tax year, this results in a maximum catch-up contribution of $11,250, bringing the total contribution limit for participants in this age group to $34,750 when including the standard $23,500 contribution. This provision provides a significant opportunity for late-career workers to accelerate their retirement savings during peak earning years, taking full advantage of tax-advantaged growth potential.

Traditional and Roth IRA Contribution Limits for 2025

The annual contribution limit for traditional and Roth IRAs in 2025 remains steady at $7,000, unchanged from 2024. Meanwhile, taxpayers aged 50 and older can continue to make an additional $1,000 catch-up contribution, raising their total annual limit to $8,000.

For Roth IRAs, income limits determine eligibility to make contributions:

• Single and Head-of-Household Filers. Full contributions are allowed for those with a modified adjusted gross income (MAGI) below $150,000 (up from $146,000 in 2024).
• Married Couples Filing Jointly. The full contribution is available for those with a MAGI below $236,000.

SIMPLE IRA Contribution Limits for 2025

In 2025, the contribution limit for SIMPLE IRA plans rises to $16,500, up from $16,000 in 2024, providing participants with an increased opportunity to save for retirement. Under SECURE 2.0 provisions, certain eligible SIMPLE plan participants can contribute even more, with the limit increasing to $17,600.

For participants aged 50 and older, the standard catch-up contribution remains at $3,500. However, for applicable plans under SECURE 2.0, the catch-up limit increases to $3,850, allowing older savers to accelerate their retirement savings even further.

Health Savings Account (HSA) Updates for 2025

Health Savings Accounts (HSAs) offer a tax-advantaged way to save for eligible medical expenses for individuals enrolled in a qualifying High Deductible Health Plan (HDHP). For 2025, the IRS has updated HDHP requirements and HSA contribution limits.

HDHP Requirements for 2025:

• Minimum Annual Deductible for Individual Coverage: $1,650 (up from $1,600 in 2024).
