Your parents may have shared advice that was fine when they were 30, but 'the world has changed significantly' since then

By making smart money choices in your 30s, you can pave the way toward financial security and independence. But in many cases, traditional advice no longer applies.

The oldest members of Generation Z are approaching their 30s, a decade when life may pick up momentum. Many get married; some have children; careers can start to take off.

Decisions made in this decade can have incredible long-term impacts. By making smart money choices now, young people may pave a smoother road toward financial security and independence in the future. But in many cases, traditional advice no longer applies.

"The world has changed significantly" since the parents of Gen Zers were in their 30s, certified public accountant Miklos Ringbauer told MarketWatch. There are many new ways to invest and tax-advantaged account types for young people to consider, which can go a long way in helping them build wealth for themselves and their children.

For Gen Zers wondering what the best places are to park their money, here are some critical ways they can build a solid financial foundation, according to experts.

Priority 1: Build an emergency savings account that can cover six months of expenses

Emergency savings might not seem exciting - perhaps this is why one-third of Gen Zers have none at all, according to a Bankrate survey. These cash reserves won't make you rich, but they are the foundation for financial stability, as they help households avoid taking on high-interest credit-card debt when surprise expenses pop up.

"Where I start, especially for young people, because our lives are just in flux, is do we have the emergency fund set up?" Clifford Cornell, a 27-year-old financial planner at Bone Fide Wealth, told MarketWatch.

Having cash to cover unexpected expenses is important at every age, but especially during your 30s as financial responsibilities, such as supporting children, start to add up.

The first step is to work toward setting up a $2,000 "mini emergency fund," which should be in a separate, dedicated savings account that isn't used for everyday expenses or for other goals (like a home down payment), to help with modest levels of unexpected spending.

After that, many financial planners recommend steadily contributing to this emergency account, while tending to your other saving and investing goals, until the balance is large enough to cover six months of expenses. This is particularly important for households that are supporting dependents, or whose jobs are less secure.

While planners had traditionally recommended three to six months of emergency savings, the average length of unemployment is now 5.7 months for those aged 35 to 44, slightly longer than the 5.3-month average for all workers, according to 2025 data.

For many families, a six-month fund is more than $20,000. Building up this cash reserve can take months, or even more than a year while balancing expenses and other savings, but it is essential.

More on this: Many Americans now need $20,000 in an emergency savings fund. Yes, really.

Priority 2: Save for retirement - and consider a Roth 401(k)

Members of Generation Z were born between 1997 and 2012, so the oldest will turn 30 in just a few months. While retirement can seem far away, it's not too early to save for a time when you won't be working.

There's some evidence that Gen Z is doing a pretty good job at saving for retirement. Still, "Most of my 30s clients, they have no retirement savings," said Ringbauer.

If your employer has a retirement plan, enroll. This may sound obvious, but about 30% of eligible workers don't participate in their employer's 401(k)-type plan, according to the Department of Labor.

It's a great way to invest automatically, as the money comes out of your paycheck before it even hits your checking account - i.e. it is forced retirement savings.

One option that has become far more common over the past decade - especially after changes made in the Secure 2.0 Act - is Roth 401(k)s. These Roth accounts launched in 2006 and are now available in nearly all workplace plans, though only about one-in-five eligible people are using it.

If you think you'll be in a lower tax bracket in your 30s than in the future (workers in their 40s and 50s typically have a higher average tax rate), contributing to a Roth 401(k) "can make a lot of sense" while you're young, said Dalton Clary, a 27-year-old financial planner at Waverly Advisors.

Workers pay taxes on the contributions today in exchange for tax-free growth and withdrawals in retirement. "The longer investment horizon also gives decades of potential tax-free compounding," Clary added. Often, a combination of both traditional and Roth accounts provides valuable tax flexibility in retirement.

When Gen Zers' parents were saving for retirement, most were saving in traditional plans. "'Reduce your taxable income today' used to be the slogan," said Ringbauer.

But today, the Roth option gives people much more flexibility in terms of withdrawals of their contributed principal before age 591/2, and allows them to use the account completely tax-free - with no required minimum distributions - in retirement. Traditional 401(k)s, on the other hand, have required minimum distributions that are taxed as income when the money is withdrawn.

How much should you contribute toward your retirement? One guideline is to save at least 15% of your pre-tax income for retirement if you want to maintain your quality of life after you stop working. This year, IRS rules allow workers in their 30s to contribute up to $24,500 into their 401(k) plans (and up to $72,000 including after-tax contributions).

At the very minimum, set your contribution rate to at least maximize any match your employer offers. "It's essentially the closest thing in personal finance to what they'd call a 'free lunch,'" Cornell said. For instance, "If you contribute 4% and your employer is going to match that 4%," that's like getting a 100% return on your contribution.

Based on national medians, households in their 30s should have at least $120,000 in net worth to feel like they can get ahead, according to a new measure by the Aspen Institute, although the number will vary by location. This includes having a modest six-week cash emergency fund as well as other financial assets or home equity equal to 10% of the area median home sale price.

Priority 3: Open a Roth IRA if you don't have a retirement plan through work

If you don't have any workplace retirement plan (about 42% of workers don't), consider opening a Roth IRA with a brokerage firm. Unlike a 401(k), which is opened through your employer and funded directly from payroll, an IRA is an individual account you fund yourself, through a transfer from your checking account, for example.

Like a Roth 401(k), the benefit of a Roth IRA is that it grows tax-free for decades, and can then be withdrawn tax-free at age 591/2. Note, however, that the limit on how much people in their 30s can contribute annually to a Roth IRA is capped at $7,500 for 2026, and gets even lower after your income hits $168,000 (or $242,000 for married couples).

Given the 15% recommended saving rate for retirement, make sure to calculate - based on your income - if you need to invest beyond that $7,500 cap, say, in a taxable brokerage to secure your future financial independence. As a reference, $7,500 is 15% of a $50,000 income.

Priority 4: Invest in a Health Savings Account for big tax breaks

Health savings accounts, launched in 2004, are investment accounts available for people who have high-deductible health-insurance plans. They are often lauded by financial experts for having a "triple tax advantage": 1. Your HSA contributions reduce your taxable income for the year; 2. The money can be invested and grows tax-free; and 3. Funds can be withdrawn tax-free at any point for medical expenses.

"HSAs are arguably one of the most tax-advantaged accounts at the federal level, even above and beyond a 401(k)," said Cornell. "I usually try not to let the HSA be the deciding factor for which health plan we want to enroll in" but if a young person doesn't need robust coverage and is OK with a high-deductible plan, "the HSA is a little cherry on top."

The maximum HSA contribution limits this year are $4,400 for individuals and $8,750 for family coverage.

While some people use HSAs to cover the current year's medical bills, young people with few medical needs can follow a strategy in which they pay for immediate medical expenses with other savings (not the HSA), so that their HSA funds can keep compounding tax-free for decades. Retirees today will spend an average of $185,500 on healthcare in retirement, according to Fidelity. For 30-year-olds today, that amount will naturally be more.

After age 65, account owners also can use the money for anything - not just health expenses - penalty-free. Withdrawals for non-health uses are taxed as ordinary income at that age.

Another hack is to keep all your medical receipts after you open the HSA, and then reimburse yourself tax-free for those old expenses years, even decades later, after there has been considerable growth on your original contribution. There is no time limit on reimbursements, so the expenses can be decades old, as long as they were incurred after the HSA was opened.

For example: In retirement, you can reimburse yourself for 30-year-old medical expenses tax-free, and then use those dollars for an HVAC repair or to buy a car. Withdrawing funds from a regular brokerage account, on the other hand, could trigger capital-gains taxes.
