Your 5-step guide to financial planning

Key takeaways
Multigenerational households are on the rise, which offers both financial challenges and opportunities for families.
One of the first steps in managing household finances is to establish a budget that accounts for household income, shared expenses, and individual contributions.
Other strategies for managing finances include building an emergency fund for unexpected expenses and exploring savings options like Health Savings Accounts (HSAs), 529 plans, and tax-advantaged investment accounts to meet healthcare, education, and long-term financial goals.
Between 1971 and March 2021, the number of Americans living in multigenerational households quadrupled, growing from about 14 million to 59.7 million people, according to Pew Research Center. That translates to 18% of the U.S. population, up from about 7% in 1971.
Why the shift? Respondents to Pew’s survey gave many reasons, but the two mentioned most often were finances and caregiving duties.
With sharp increases in house prices, people marrying later and student debt on the rise, younger generations are more likely to live with their parents longer to save on living expenses.
On the caregiving front, people in the sandwich generation are taking care of their children and their parents simultaneously. Sometimes, multigenerational living is simply the easiest option both practically and to avoid the cost of long-term care such as assisted living.
For all the potential cost savings, multigenerational households can still face financial stress—but there are strategies that can help you better manage the household finances.
Multigenerational homes are likely to have more complex financial needs and higher costs than single-family households—but more members mean more contributors, too. Here are some steps you can follow when creating a family budget for your multigenerational household.
Once you’ve determined all your household expenses and who’s responsible for what, consider automating contributions to a shared bank account from family members’ incomes. It can also be useful to set up a budgeting app so all contributing adults can see the state of the household finances at any time.
Setting up an emergency fund that is easily accessible can help your multigenerational household better manage unexpected expenses, such as a job loss, medical bill or car or home repair. To build up funds, you should make small contributions on a regular basis. Schedule automatic transfers from your checking account to a savings account that’s reserved for unexpected situations.
However, try to avoid putting too much money into your emergency fund, because this type of account will likely come with a low interest rate. Once you meet your savings goal for your emergency fund—typically three to six months’ worth of household expenditure—shift ongoing contributions into a tax-advantaged investment account or high-yield savings account, where it can potentially earn more interest. (Keep reading to learn more about these types of accounts.)
Living in a multigenerational household means monitoring multiple financial goals. For example, older adults may require medical treatment or long-term care in the future, while children who are planning to go to college will benefit from funds to help with tuition and other expenses.
Adults: If you’re enrolled in a high-deductible health plan, you can open a Health Savings Account (HSA) and contribute to it until you turn 65. The money in an HSA grows tax-free and isn’t taxed when it’s withdrawn for eligible expenses. HSAs can be used to pay Medicare and other related insurance premiums as well as out-of-pocket expenses into retirement.
You may also want to consider building savings in a traditional or Roth IRA and use that to help cover medical expenses once you turn 59 ½. (Note that withdrawals from traditional IRAs are taxed, and there are penalties if you withdraw money from an IRA early.)
Children: If your kids have college in their future, consider opening a 529 plan. A 529 plan is an investment plan in which contributions plus any earnings grow tax-deferred and remain tax-free if the funds are withdrawn to pay for certain qualifying education expenses, including some study-abroad costs, at any college or university. (A list of qualifying institutions, including those in other countries, is here.)
Another option is a prepaid tuition plan, where you select a participating college or university and purchase credits or units at the current price for your child to use to cover future tuition and fees.
Note that if you’re a caregiver for a parent, you may be able to claim them as a dependent on your taxes and deduct some of the cost of supporting them, just as you do for any dependent children.
A tax diversified investment strategy, in which you maintain a mix of investment accounts with different tax treatments, may help you lower your taxes over your lifetime. Keep in mind that these types of accounts are for the long term.
Tax advantaged accounts: 401(k)s, 403(b)s and traditional IRAs allow you to contribute pre-tax dollars or to deduct contributions from your taxes.
Tax free accounts: Roth IRAs, 529 plans and HSAs are examples of investment vehicles with benefits such as tax exemption or deferral.
Fully taxable accounts: Money market accounts and traditional brokerage accounts offer no tax advantages but can play an important role in your financial plan.
Easy access to tax-advantaged and tax-free funds may be limited, so you and other decision makers in your multigenerational household will need to consider when you might need this money and how much risk you’re comfortable with. Consulting with a financial professional at your bank can help you craft a tax diversification strategy that makes sense for your multigenerational household.
How to pass on wealth—including property—fairly and with minimal tax consequences is a common concern among multigenerational households. You may have already taken care of some of the estate planning basics, such as creating a will and naming beneficiaries.
Consider working with an estate planning attorney to pull it all together by creating a comprehensive estate plan that includes documents like powers of attorney and healthcare directives, too, to make sure all members of your multigenerational household will be secure if you or another earner were to die.
Talking about money is tricky for most people, but it’s incredibly important when you live in a multigenerational household. Achieving all family members’ financial goals and ensuring a secure future for your multigenerational household requires open and honest communication. Encourage everyone to share their financial priorities, including those who are too young to contribute to household expenses.
By keeping lines of communication open, setting ground rules early on and having a shared financial plan, you can avoid problems down the line and help your household run like clockwork.
