A WSI account is a workplace savings account that lets you set aside money for work-related expenses before taxes are taken out

WSI stands for Work Savings Initiative, though the term is sometimes used loosely to describe workplace savings or benefits accounts tied to your employer. The core idea is simple: you contribute money from your paycheck, your employer may match part of it, and you use those funds to pay for may have access to expenses—usually health care, dependent care, or transit costs. Because the money goes in before federal income tax and Social Security tax are calculated, you pay less in taxes overall.

The most common WSI-type accounts are Flexible Spending Accounts (FSAs) and Health Savings Accounts (HSAs). Both let you set aside pre-tax dollars, but they work differently and have different rules about what you can spend the money on, how much you can contribute, and what happens to unused funds at the end of the year.

Key Takeaways

  • WSI accounts use pre-tax money, which reduces your taxable income and the amount you owe in federal income tax and Social Security tax.
  • The most common types are Flexible Spending Accounts (FSAs) for health and dependent care, and Health Savings Accounts (HSAs) paired with high-deductible health plans.
  • You choose how much to contribute during your employer's open enrollment period, usually once per year, and the money is deducted from each paycheck automatically.
  • FSAs have a "use it or lose it" rule—unspent money at the end of the year is forfeited, though some plans allow a small carryover or grace period.
  • HSAs let you roll over unused money year to year and can be invested, making them work more like a savings account than a spending account.

How money flows in and out of a WSI account

When you enroll in a WSI account during open enrollment, you tell your employer how much to deduct from your paycheck each pay period. That money goes into a separate account—either managed by your employer's benefits administrator or by a third-party company like HealthEquity or WageWorks. You do not pay federal income tax, Social Security tax, or Medicare tax on that money, which is the main financial benefit.

To spend the money, you typically use a debit card issued by the account administrator, submit receipts for reimbursement, or pay out of pocket and request a refund. The account administrator checks that your expense qualifies under the plan rules, and if it does, they reimburse you or credit your card. Some accounts let you set up recurring payments for regular expenses like monthly insurance premiums.

The catch is timing: you must incur the expense during the plan year (usually January 1 to December 31) to use the money. If you contribute $2,500 to an FSA and spend only $1,800 by December 31, the remaining $700 is typically lost—you cannot roll it over to next year or get it back as a refund.

FSA vs. HSA: which type of WSI account you might have

A Flexible Spending Account (FSA) is the most common WSI account. It covers may have access to medical expenses (copays, deductibles, prescriptions, dental work, vision care) and dependent care expenses (child care, adult day care). You choose your contribution amount each year, up to a limit set by the IRS—for 2024, the limit is $3,300 for health care FSAs and $5,000 for dependent care FSAs. The money must be spent in the plan year or it is forfeited, though some employers allow a $610 carryover or a 2.5-month grace period into the next year.

A Health Savings Account (HSA) is different. It is only available if you are enrolled in a high-deductible health plan (HDHP), and it works more like a savings account. You can contribute up to $4,150 per year (individual coverage) or $8,300 (family coverage) for 2024. Unused money rolls over year to year, and you can invest it in stocks, bonds, or mutual funds. You can withdraw money tax-free for may have access to medical expenses at any time, even years later. If you withdraw money for non-medical expenses before age 65, you pay income tax plus a 20% penalty; after 65, you pay only income tax.

Some employers offer both an FSA and an HSA, but you cannot contribute to both in the same year if the FSA covers medical expenses. You can, however, have a dependent care FSA alongside an HSA.

What expenses may have access to under a WSI account

may have access to medical expenses include copays, coinsurance, deductibles, prescription drugs, dental work, vision care (glasses, contacts, exams), hearing aids, and certain medical equipment. They do not include health insurance premiums (with rare exceptions), cosmetic procedures, or over-the-counter medications unless prescribed by a doctor.

Dependent care expenses cover child care, preschool, adult day care for an elderly parent, and summer camp—but only if the care allows you or your spouse to work. It does not cover education (K-12 tuition or college), overnight camps, or care for a spouse.

Transit expenses, if your employer offers a transit FSA, cover public transportation passes, parking at a transit station, and vanpool fees. They do not cover parking at your workplace or gas for a personal vehicle.

The IRS publishes a full list of may have access to expenses on its website. If you are unsure whether an expense qualifies, ask your account administrator before you spend the money—once it is spent, you cannot get a refund if it turns out to be ineligible.

How to enroll and manage your WSI account

Enrollment happens during your employer's open enrollment period, usually in the fall for a plan year starting January 1. You log into your employer's benefits portal, select the account type and contribution amount, and confirm. The deduction starts with your next paycheck and continues until the end of the plan year.

Throughout the year, you track your spending and balance. Most account administrators provide a website or mobile app where you can see your balance, submit receipts, and request reimbursements. Keep all receipts and documentation—the IRS can audit WSI accounts, and you may need to prove that an expense was may have access to.

If you leave your job, you usually have 60 days to submit claims for expenses you incurred while employed. After that, the account closes and any remaining balance is forfeited (unless your employer offers COBRA continuation, which is rare for FSAs).

What happens to money you do not spend

For FSAs, the "use it or lose it" rule means unspent money at the end of the plan year is forfeited. Some employers allow a carryover of up to $610 (for 2024) into the next year, or a grace period of up to 2.5 months into the next plan year to incur expenses. Check your plan documents to see if either option applies to you.

For HSAs, unused money is yours to keep. It rolls over automatically, and you can let it grow year after year. This makes HSAs more flexible if you are healthy and do not expect large medical expenses in the near term.

If you are unsure whether your balance will carry over, ask your benefits administrator or check your plan summary. Losing money to the forfeiture rule is common, so many people contribute conservatively—only what they are confident they will spend.

Tax savings and the real benefit of a WSI account

The main advantage of a WSI account is the tax savings. If you contribute $2,500 to a health care FSA, you avoid paying federal income tax, Social Security tax, and Medicare tax on that $2,500. For someone in the 22% federal tax bracket plus 7.65% in payroll taxes, that is roughly $740 in taxes saved on a $2,500 contribution.

HSAs offer an additional benefit: if you do not spend the money in the year you contribute it, you can invest it and let it grow tax-free. This makes HSAs a powerful retirement savings tool if you can afford to pay for medical expenses out of pocket and let the HSA balance compound.

The downside is the restriction on what you can spend the money on and, for FSAs, the risk of losing unspent funds. If you are not sure you will use the money, contributing less or skipping the account altogether may be safer than guessing wrong and forfeiting the balance.

Frequently Asked Questions

Can I change my WSI contribution amount during the year?

No, not usually. You lock in your contribution amount during open enrollment, and it stays the same for the entire plan year. You can change it only if you have a may have access to life event—marriage, divorce, birth of a child, loss of other health coverage, or a significant change in your dependent care needs. Your employer's benefits team can tell you what counts as a may have access to event.

What happens to my WSI account if I get fired or laid off?

You have 60 days after your employment ends to submit claims for expenses you incurred while employed. After that, the account closes and any remaining balance is forfeited. Some employers offer COBRA continuation for health insurance, but FSAs are rarely included. HSAs are portable—you keep the account and the money even after you leave your job.

Can I use my WSI debit card for anything other than may have access to expenses?

Technically no, but some debit cards do not validate at the point of sale. If you use the card for an ineligible expense, you may be asked to repay the amount, or the account administrator may flag it during a reconciliation. It is safer to submit receipts for reimbursement than to use the card for anything you are unsure about.

Do I need receipts to prove my WSI expenses?

Yes. Keep all receipts and documentation. The IRS can audit WSI accounts, and you must be able to prove that an expense was may have access to. If you cannot provide a receipt, the account administrator may deny the reimbursement or ask you to repay it.

Can I have both an FSA and an HSA at the same time?

Not if both cover medical expenses. You can have a dependent care FSA and an HSA in the same year, or a transit FSA and an HSA. But if you have an HSA, you cannot also have a health care FSA—the IRS treats them as duplicative coverage.
