Let’s dive into some key updates for 2025 — because who doesn’t enjoy crunching a few numbers?

401(k) and 403(b) contribution limits

Good news! In 2025, the employee contribution limit for 401(k) and 403(b) plans increases to $23,500 for those under 50 (up from $23,000 in 2024). Catch-up contributions for those 50 and older remain at $7,500, but if you’re 60-63 by the end of 2025, you can contribute an additional $11,250 as part of the SECURE 2.0 super 401(k) catch-up contribution.

Total 401(k) contribution limits

The combined employee and employer contribution limit is also going up in 2025. For those under 50, the cap increases from $69,000 to $70,000, and for those 50 and older, it rises to $77,500. If you’re 60-63, the total limit, including catch-up contributions, climbs to $81,250.

SEP IRA contribution limits

Contributing to a SEP IRA? The 2025 limit increases from $69,000 to $70,000.

Traditional and Roth IRA contribution limits

No changes here — contribution limits from traditional IRAs and Roth IRAs remain at $7,000 (or $8,000 for those eligible for catch-up contributions). Not the most exciting update, right?

HSA contribution limits

Health savings account (HSA) limits are increasing! In 2025, individuals can contribute up to $4,300 (up from $4,150), while families can contribute $8,550 (up from $8,300). The $1,000 catch-up for those 55 and older remains unchanged.

FSA contribution limits

Flexible spending accounts (FSAs), the "less fun sibling" of HSAs, see a modest increase from $3,200 in 2024 to $3,300 in 2025.

The cost-of-living adjustment (COLA) for Social Security benefits in 2025 is 2.5%. While it’s a smaller bump (due to lower inflation), it’s still an increase to be thankful for.

In 2025, Social Security tax applies to the first $176,100 of income, up from $168,600 in 2024.

Standard deduction increase

The standard deduction rises in 2025 to $15,000 for single filers (a $400 increase) and $30,000 for married couples filing jointly (an $800 increase).

Annual gift exclusion

The annual gift tax exclusion limit increases from $18,000 to $19,000 per recipient in 2025. Feel free to spread the holiday cheer — tax-free!

Lifetime estate tax exemption

The estate tax exemption per individual jumps to $13.99 million in 2025 (up from $13.6 million in 2024), offering additional planning opportunities for high-net-worth individuals.

Retirement contribution base increase

The maximum income used to calculate retirement plan contributions increases from $345,000 in 2024 to $350,000 in 2025.

Roth IRA phase-out range

For 2025, the Roth IRA income phase-out range increases to $150,000–$165,000 for single filers and $236,000–$246,000 for married filers (up from $146,000–$161,000 and $230,000–$240,000, respectively).
