Question 1

How much can I borrow from my 401(k) and how is the limit set?

Accepted Answer

If your plan permits loans, the IRS caps the amount at the lesser of $50,000 or 50% of your vested balance. A special rule lets you borrow up to $10,000 even if that exceeds half your balance. The $50,000 ceiling is also reduced by your highest outstanding loan balance over the prior 12 months. Not every plan offers loans, and some limit you to one or two at a time, so check your summary plan description. Repayment is typically through payroll deduction over up to five years, or longer if the lo

Question 2

What happens to my 401(k) loan if I quit or lose my job?

Accepted Answer

When you leave, most plans accelerate the loan and treat the outstanding balance as due. Thanks to a rule from the 2017 tax law, you now have until your tax-filing deadline, including extensions, for the year you separate to repay the balance or roll an equivalent amount into an IRA or new plan (a qualified plan loan offset). If you cannot cover it in time, the unpaid balance becomes a deemed distribution: it is taxed as ordinary income, and if you are under 59 1/2 you owe an additional 10% pena

Question 3

Is paying myself back interest on a 401(k) loan really a benefit?

Accepted Answer

It sounds appealing that the interest you pay goes back into your own account rather than to a bank, but the picture is more complicated. While the borrowed money is out of the market, it misses potential investment growth, which historically has outpaced the modest loan interest rate. You effectively swap market returns for the loan rate. There is also a subtle double-taxation angle: you repay the loan with after-tax dollars, and later pay tax again on those dollars when you withdraw them in re

Question 4

What is a 401(k) in-service distribution and when am I eligible for one?

Accepted Answer

An in-service distribution lets you take money out of your 401(k) while still employed there, without leaving your job. Availability depends entirely on your plan's rules. Many plans allow in-service distributions of after-tax or rollover-source money at any age, and some permit distribution of employer or pre-tax funds once you reach age 59 1/2. People use in-service distributions to roll funds into an IRA for more investment choices, or to execute an in-plan Roth conversion. Taking a pre-tax i

Question 5

What contribution limits apply to a 457(b) plan and can I stack it with a 401(k)?

Accepted Answer

A governmental 457(b) has its own employee deferral limit set annually by the IRS, and crucially, it is separate from the 401(k)/403(b) limit. If your employer offers both a 457(b) and a 401(k) or 403(b), you can generally max out each one independently in the same year, effectively doubling your tax-advantaged deferral room. This makes 457(b) plans valuable for public-sector and some nonprofit employees. The 457(b) also has a unique final-three-years special catch-up that can let you contribute

Question 6

How is a nongovernmental 457(b) plan different and riskier than a governmental one?

Accepted Answer

A governmental 457(b) holds assets in trust for you, so your money is protected if the employer has financial trouble, much like a 401(k). A nongovernmental 457(b), offered by some tax-exempt nonprofits and hospitals to select highly paid employees, is different: the assets legally remain the employer's property and are subject to the employer's creditors. That creditor exposure is the big risk. If the nonprofit becomes insolvent, your deferred savings could be lost. Nongovernmental 457(b) money

Question 7

What investment options does a 403(b) plan typically offer compared to a 401(k)?

Accepted Answer

Historically, 403(b) plans, common at schools, hospitals, and nonprofits, were dominated by annuity products sold by insurance companies, many carrying high fees and surrender charges. Many 403(b) menus still include costly variable annuities alongside mutual funds, and the choices can be worse than a typical 401(k). Because fees quietly erode returns, scrutinize each option's expense ratio and any annuity surrender period before investing. If your 403(b) offers a low-cost index fund option, tha

Question 8

What are the TSP fund choices and how low are the fees?

Accepted Answer

The federal Thrift Savings Plan offers a small, simple menu: individual index funds covering U.S. large-cap stocks (C Fund), small and mid-cap (S Fund), international (I Fund), bonds (F Fund), and government securities (G Fund), plus target-date Lifecycle (L) funds that blend them. The G Fund is unique in that it cannot lose value and pays a government-rate yield. The TSP is renowned for having some of the lowest administrative fees of any retirement plan in the country, a fraction of what most

Question 9

How does the TSP match work for federal employees and service members?

Accepted Answer

Under the Federal Employees Retirement System (FERS) and the military Blended Retirement System, the government contributes generously. FERS employees get an automatic 1% of pay regardless of whether they contribute, plus a match on the first 5% they defer: dollar-for-dollar on the first 3% and 50 cents on the next 2%. Contribute at least 5% and you receive an effective 5% match on top of the automatic 1%. Contributing less than 5% forfeits free money, so 5% is the minimum every eligible federal

Question 10

Can I roll a TSP account into an IRA or a private 401(k) after leaving government?

Accepted Answer

Yes. After you separate from federal service, you can roll your TSP into a traditional IRA, a Roth IRA (as a taxable conversion for pre-tax balances), or a new employer's 401(k). The traditional TSP portion moves to pre-tax accounts tax-free, while Roth TSP dollars roll to a Roth IRA tax-free. Before rolling out, weigh what you would give up. The TSP's fees are so low that many advisors suggest leaving the money there. Rolling out gains you broader investment choices and features like partial Ro

Question 11

What is a partial 401(k) match versus a dollar-for-dollar match?

Accepted Answer

A dollar-for-dollar (full) match adds one dollar for every dollar you contribute up to a cap, so a 100% match on the first 4% of pay gives you 4% free when you defer 4%. A partial match adds a fraction, such as 50 cents per dollar; a 50% match on the first 6% gives you 3% free when you defer 6%. To capture the maximum, you must contribute up to the cap of pay the formula references, not just match the stated percentage. Read your formula carefully, because a 50%-on-6% plan requires a larger defe

Question 12

Are employer 401(k) contributions ever taxed as income when they go in?

Accepted Answer

Traditional employer match and profit-sharing contributions are not taxed when deposited; they grow tax-deferred and are taxed as ordinary income when you withdraw them in retirement. They do not count as taxable wages on your W-2 in the year contributed. SECURE 2.0 now lets plans offer a Roth employer match, which is different: if you elect a Roth match, that amount is included in your taxable income for the year it is contributed, but then grows tax-free. Also note that employer contributions

Question 13

How do employer profit-sharing contributions to my 401(k) work?

Accepted Answer

Profit-sharing is a discretionary employer contribution separate from any match. The company decides each year whether and how much to contribute, often as a uniform percentage of each eligible employee's pay, and it does not require you to defer anything yourself to receive it. It counts under the overall Section 415(c) combined limit, not your personal deferral limit. Profit-sharing contributions typically follow the plan's vesting schedule, so you may not fully own them if you leave early. Be

Question 14

Can I contribute to a 401(k) at two different jobs and how do I avoid over-contributing?

Accepted Answer

You can participate in a 401(k) at each employer, but your personal elective-deferral limit set by the IRS applies to you across all plans combined, not per plan. If you contribute at two jobs, add up your deferrals to make sure the total stays under the annual limit. This is easy to overshoot when you switch jobs mid-year, because a new employer's payroll system does not know what you already deferred. If you go over (an excess deferral), notify a plan by the deadline and request a corrective d

Question 15

What is the overall combined 401(k) contribution limit including employer money?

Accepted Answer

Beyond your personal deferral limit, the IRS caps the total that can go into your 401(k) from all sources in a year, your deferrals plus employer match plus profit-sharing plus after-tax contributions, under Section 415(c). This overall ceiling is much higher than the employee-only limit and is also indexed annually, so check irs.gov for the current figure. Age-50 catch-up deferrals sit on top of even this combined limit. This combined cap is what makes the mega backdoor Roth possible: after max

Question 16

When can I start withdrawing from my 401(k) penalty-free, and does leaving my job change that?

Accepted Answer

The standard age for penalty-free 401(k) withdrawals is 59 1/2. Take money out before then and you generally owe a 10% early-withdrawal penalty on top of ordinary income tax, with limited exceptions. One important exception is the Rule of 55: if you leave your job in or after the calendar year you turn 55 (50 for certain public-safety workers), you can withdraw penalty-free from that specific employer's 401(k), though income tax still applies. It only covers the plan at the job you just left, no

Question 17

What is an in-plan Roth conversion inside my 401(k) and why would I use one?

Accepted Answer

An in-plan Roth conversion (also called an in-plan Roth rollover) moves pre-tax or after-tax money already in your 401(k) into the Roth portion of the same plan, if your plan permits it. You pay ordinary income tax on any pre-tax amount converted in that year, and the money then grows tax-free. The most common use is the in-plan mega backdoor Roth: you make after-tax contributions and immediately convert them to Roth inside the plan, minimizing taxable growth before conversion. Converting long-s

Question 18

Does my 401(k) contribution reduce my taxable income for the year?

Accepted Answer

Traditional (pre-tax) 401(k) deferrals reduce your federal taxable wages dollar for dollar, lowering the income tax you owe this year. If you defer $10,000 pre-tax and are in the 24% bracket, you save roughly $2,400 in federal tax now. This reduction shows up because the deferral is excluded from Box 1 wages on your W-2. Roth 401(k) deferrals do not reduce current taxable income, since they are made with after-tax dollars, but they grow and withdraw tax-free later. Note that pre-tax deferrals do

Question 19

How does 401(k) auto-enrollment affect me and can I change the default rate?

Accepted Answer

Many plans now automatically enroll new hires at a default deferral rate, often 3% to 6%, unless you opt out. Under SECURE 2.0, most newly created 401(k) and 403(b) plans are required to auto-enroll eligible employees starting at 3% to 10%. The default investment is usually a target-date fund matched to your expected retirement year. You are never stuck with the defaults. Log into your plan portal to raise the rate (crucial if the default is below the match threshold), change your investments, o

Question 20

What is 401(k) auto-escalation and should I keep it turned on?

Accepted Answer

Auto-escalation automatically increases your deferral rate by a set amount, often 1% of pay, each year up to a cap, without you having to remember to do it. SECURE 2.0 requires many new auto-enrollment plans to auto-escalate participants annually until they reach at least 10%. For most savers, keeping it on is smart, because the increases are small enough to be painless yet compound powerfully over a career, and they counter the natural tendency to under-save. You can opt out or adjust the cap i

Question 21

How do I roll an old IRA into my current 401(k), and why would I?

Accepted Answer

If your employer's plan accepts incoming rollovers (most do), you can move a traditional IRA into your 401(k) via a direct trustee-to-trustee transfer. You cannot roll a Roth IRA into a 401(k), only pre-tax IRA money and only the pre-tax portion. The main reason to do this reverse rollover is to clear pre-tax IRA balances out of the way so you can execute a clean backdoor Roth without triggering the pro-rata rule, which would otherwise tax part of your conversion. Other reasons include access to

Question 22

What are catch-up contributions for older workers in employer plans?

Accepted Answer

Once you reach age 50, the IRS lets you contribute an extra catch-up amount to your 401(k), 403(b), or governmental 457(b) on top of the standard employee deferral limit. The catch-up figure is set annually and indexed for inflation, so verify the current number at irs.gov. SECURE 2.0 added a higher catch-up for workers ages 60 through 63, and beginning in 2026 it requires that catch-up contributions by higher earners (those over a wage threshold) be made as Roth rather than pre-tax. The 457(b)

Question 23

Can I make after-tax (non-Roth) contributions to my 401(k) beyond the normal limit?

Accepted Answer

Some plans allow after-tax contributions, a third bucket distinct from pre-tax and Roth. These let you contribute beyond your personal deferral limit, up to the overall combined Section 415(c) ceiling after accounting for your deferrals and the employer match. The contributions are made with already-taxed dollars, and only the growth is taxable later, unless you convert them to Roth. The reason people use this bucket is the mega backdoor Roth: contribute after-tax dollars, then convert them to R

Question 24

How do I actually initiate a 401(k) rollover step by step?

Accepted Answer

First, open the receiving account (a new employer's 401(k) or an IRA) so you have somewhere for the money to land. Second, contact your old plan's recordkeeper and request a direct rollover, giving them the receiving custodian's details; specify direct so no tax is withheld. Third, tell them how to handle the check, ideally payable to the new custodian for your benefit, mailed to you to forward or sent directly. Keep pre-tax and Roth balances separated during the move so the tax character is pre
