The financial industry loves a year-end checklist. Most of them assume you've already maxed your 401k, own a taxable brokerage account with unrealized losses to harvest, and are deciding whether to do a Roth conversion before your marginal rate resets. If that's not you — if you're earning $75,000, working through debt, and still figuring out the savings priority order — most of those lists are noise.
This one is the practical version. At $75,000 gross (approximately $56,000-58,000 take-home depending on state and filing status), there are a handful of year-end moves that genuinely matter and several that can wait. The critical ones have hard December 31 deadlines. The rest have more flexibility than most articles admit. Here's what to actually do before the calendar resets.
Move 1: Confirm You Got the Full 401k Employer Match
The Free Money That 30% of Eligible Workers Leave on the Table
The 401k employer match is the highest guaranteed return available in personal finance — 50-100% instantly, before any investment returns. Yet approximately one-third of employees eligible for a match don't contribute enough to get all of it.
At $75,000 with a typical 6% employer match, the employer will contribute up to $4,500/year ($375/month). To receive the full match, you need to contribute at least 6% yourself — $4,500/year or $375/month from your paycheck. Log into your 401k account and confirm your current contribution rate.
If you haven't been contributing at least 6% all year, check whether there's still time to catch up. Some plans allow you to increase contributions significantly in the final months of the year to ensure you hit the match threshold. Others calculate the match on a per-paycheck basis — if you front-loaded or contributed unevenly, you may have missed some matches. Call your 401k plan administrator in November or early December to confirm your match status before the plan year closes.
Hard deadline: Your last paycheck of the year. After that, the year's match calculation is complete.
Move 2: Use Your Flexible Spending Account Before It Expires
The December 31 Deadline Most People Miss
A Flexible Spending Account (FSA) is an employer-sponsored benefit that lets you set aside pre-tax dollars for healthcare expenses. At $75,000, contributing $1,500-2,000 to an FSA saves approximately $375-500 in federal income taxes. The brutal catch: FSA funds expire at the end of the plan year for most plans.
The "use it or lose it" rule: unspent FSA balances generally must be forfeited at year-end (some plans allow a $610 rollover or a 2.5-month grace period — check your specific plan). If you have unspent FSA funds, December is the time to use them.
Eligible FSA expenses include: eyeglasses and contact lenses, dental work (fillings, cleanings, orthodontia), over-the-counter medications, first aid supplies, sunscreen (SPF 15+ for medical necessity), and hundreds of other items. The FSA Store (fsastore.com) lists every eligible item. If you have a balance remaining: schedule any pending dental or vision appointments in December, buy a year's supply of eligible OTC items, or use the balance for a medical visit you've been deferring.
Hard deadline: December 31 (or your plan's specific grace period end — check your summary plan description).
Move 3: Check Your 401k Annual Contribution Limit
The $23,000 Cap and What Happens If You're Behind
The 2024 401k employee contribution limit is $23,000 ($30,500 if you're 50 or older with catch-up contributions). At $75,000 salary, contributing the full $23,000 would mean directing 30.7% of your gross income to the 401k — almost certainly more than most $75,000 earners do. The median employee contribution rate is around 7-8% of salary, or $5,250-$6,000 at this income level.
The year-end 401k check isn't about maxing the account — it's about two things:
1. Did you accidentally over-contribute? Rare, but if you changed jobs mid-year and had a 401k at both employers, you may have contributed to two plans. The limit is per person, not per employer. Check the combined total across all employers. Over-contributing has tax consequences that require corrective distributions.
2. Is there room for a catch-up contribution if your cash flow allows? If you got a bonus in Q4 or had lower expenses than expected, increasing your 401k contribution in November-December is one of the most tax-efficient ways to use that money. A $2,000 additional 401k contribution saves approximately $440-$480 in federal income tax at the 22% bracket.
Hard deadline: Your last paycheck of the calendar year (some plans allow direct contributions through December 31).
Move 4: Decide Whether to Make Your Roth IRA Contribution Before April 15 or Now
The Deadline That's More Flexible Than Most People Think
The Roth IRA contribution deadline is Tax Day of the following year — April 15, 2025 for the 2024 tax year. This means you do NOT have to contribute by December 31. You have until April 15, 2025 to make your 2024 Roth IRA contribution of up to $7,000 ($8,000 if 50+).
Why might you choose to wait until after December 31? Income uncertainty. Roth IRA eligibility phases out at $146,000 (single, 2024) and $230,000 (married filing jointly). If you're not sure whether you'll exceed those limits by year-end due to a year-end bonus, overtime, or other variable income, waiting until January or February — when you have a clearer picture of your total 2024 income — prevents having to remove an excess contribution.
At $75,000 salary with no other complications, you're well under the income phase-out and can contribute anytime. If you have the cash and haven't contributed yet this year, contributing in December rather than waiting until April means an additional 4-month investment period in a tax-free account — at 7% annualized, $7,000 invested 4 months earlier is worth an additional $163 in growth. Modest, but real. The more important reason to do it now: if you wait until April, many people never get around to it.
Deadline for this year's contribution: April 15, 2025 (but do it now if you have the funds). For the full Roth IRA mechanics, income limits, and contribution rules, our complete Roth IRA guide covers everything you need to know before contributing.
Move 5: Check Your HSA Balance and Decide Whether to Invest It
The Year-End HSA Move That Builds Long-Term Wealth
If you have a Health Savings Account (HSA) through a high-deductible health plan, two year-end checks apply:
Contribution maximum for 2024: $4,150 individual / $8,300 family. Unlike FSAs, HSA funds roll over completely — there's no use-it-or-lose-it rule. You have until Tax Day (April 15, 2025) to make 2024 contributions. But if you're switching to a non-HDHP plan in 2025 (perhaps through open enrollment), your 2024 HSA contribution deadline is December 1, 2024 (the "last-month rule" requires you to be enrolled in an HDHP for the full month of December to count that month toward your contribution limit).
Investment threshold: Many HSA administrators require a minimum cash balance ($1,000-$2,000) before you can invest the rest in index funds. If your HSA balance has grown above that threshold and you haven't moved the excess into the investment side, do it now. HSA funds invested in index funds grow tax-free for medical expenses — it's one of the only triple-tax-advantaged accounts available. For how the HSA stacks up against Roth IRA contributions in priority order, our breakdown of whether to max the HSA or Roth IRA first covers the decision framework at different income and healthcare-use levels.
Move 6: Review Your Automatic Savings Rate and Set 2025 Increases
The 5-Minute Change That Compounds Over Decades
December is the natural moment to review your automatic savings setup before the new year starts. Increasing your savings rate by 1-2% now — before January 1 — means every paycheck in 2025 automatically saves more without requiring willpower or monthly decisions.
At $75,000 salary, each 1% increase in your 401k contribution rate diverts $750/year into retirement savings and reduces your take-home by approximately $585/year (the tax savings soften the take-home reduction). A 2% increase: $1,500 more in retirement savings, approximately $1,170 less in annual take-home — roughly $98/month less in spending for $1,500 more in retirement investing. Most people at this income level can absorb $98/month without a meaningful lifestyle change.
The behavioral insight: rate increases set in December take effect in January, when spending habits reset anyway (post-holiday spending usually drops naturally). Setting the increase during the December/January transition is the lowest-friction moment for a savings rate change. Our guide to automating your finances and savings with automatic paycheck transfers covers the step-by-step setup for paycheck automation that removes the monthly decision-making entirely.
Move 7: Estimate Whether You'll Owe Taxes or Get a Refund
The W-4 Adjustment That Prevents a Painful April Surprise
At $75,000 salary with standard withholding, most employees are roughly on target with their federal tax liability. But specific situations create under-withholding that results in an April tax bill — plus potential penalties if the underpayment exceeds $1,000:
You may owe more than withheld if: you have significant freelance or side income that didn't have taxes withheld, you realized capital gains from selling investments, you converted a traditional IRA to Roth IRA this year, or you started a new job mid-year at different withholding. If any of these apply, estimate your total 2024 tax liability using the IRS Tax Withholding Estimator (free at irs.gov) or a tax software preview. If you're likely to owe more than $1,000, making a fourth-quarter estimated tax payment by January 15, 2025 avoids the underpayment penalty.
Conversely, if you're getting a large refund every year, you've been giving the IRS an interest-free loan. Adjusting your W-4 to reduce over-withholding puts that money back in your paycheck monthly rather than waiting for April.
