Why 401(k) Contributions Are Powerful for NY Taxpayers

If you live in New York, especially NYC, you face some of the highest combined tax rates in the country. Contributing to a traditional 401(k) provides immediate tax relief at both the federal AND state level.

AgeMaximum Contribution
Under 50
$23,000
50 and older
$30,500 (includes $7,500 catch-up)

The NY Tax Advantage

Every dollar you contribute to a traditional 401(k) reduces your taxable income. For an NYC resident in the 22% federal bracket, 6% NY State bracket, and 3.8% NYC bracket, maxing out your 401(k) saves:

$23,000 contribution × 31.8% combined marginal rate = $7,314 in annual tax savings

That's over $600 per month in reduced taxes!

How It Works: Before and After

Example: $100,000 Income, NYC Resident, Single

Without 401(k) Contributions:

  • Taxable income: $100,000
  • Total income taxes: ~$29,884
  • Take-home pay: $70,116
  • With $23,000 401(k) Contribution:

  • Taxable income: $77,000
  • Total income taxes: ~$22,570
  • 401(k) saved: $23,000
  • Cash take-home pay: $54,430
  • Total wealth building: $77,430
  • You reduce taxes by $7,314 while building $23,000 in retirement savings!

    Strategies to Maximize Your 401(k)

    1. Contribute At Least to the Match

    Most employers match a percentage of your contributions (often 3-6%). This is free money—never leave it on the table.

    2. Front-Load If Possible

    If your budget allows, maximize contributions early in the year. This gives your money more time to grow tax-free.

    3. Consider the Mega Backdoor Roth

    Some 401(k) plans allow after-tax contributions that can be converted to Roth. The total 401(k) limit (including employer contributions) is $69,000 in 2024.

    4. Coordinate with IRA Contributions

    You can contribute to both a 401(k) and an IRA. For 2024, IRA limits are $7,000 ($8,000 if 50+).

    Traditional vs. Roth 401(k)

    Many employers now offer Roth 401(k) options. Here's how to decide:

    Choose Traditional 401(k) if:

  • You're in a high tax bracket now
  • You expect lower income in retirement
  • You want the immediate NY tax savings
  • Choose Roth 401(k) if:

  • You expect higher taxes in retirement
  • You're younger with lower current income
  • You want tax-free withdrawals later
  • For most high-earning NYCers, traditional makes sense due to the high current tax rates.

    The NY 529 Plan Bonus

    After maxing your 401(k), consider NY's 529 plan for additional state tax savings. You can deduct up to $5,000 ($10,000 married) from NY taxable income.

    Common Mistakes to Avoid

  • Not contributing enough to get the full match - This is leaving free money behind
  • Withdrawing early - 10% penalty plus all taxes become due
  • Forgetting to update beneficiaries - Keep these current
  • Not increasing contributions with raises - Boost your percentage when income grows
  • Action Steps

  • Log into your 401(k) provider
  • Increase your contribution percentage
  • Aim to max out ($23,000 or $30,500 if 50+)
