How to Open and Fund Your Health Savings Account

By Cassandra Finch · Education and Health Savings Writer

You need a high-deductible health plan first, then you can open an HSA through a bank or financial institution

An HSA is not something you get from your employer or the government — it is a savings account you open at a bank, credit union, or investment firm, much like a regular savings account. But you can only open one if you are enrolled in a high-deductible health plan (HDHP), a type of health insurance with lower monthly premiums and higher out-of-pocket costs. Your health plan provider will tell you whether your plan qualifies as an HDHP. If it does, you can then open an HSA at any financial institution that offers them.

The process takes about 15 to 30 minutes online or in person. You will need your Social Security number, proof of HDHP coverage (usually a document from your health plan), and a way to fund the account — either a bank transfer or payroll deduction if your employer offers it. Some employers set up HSAs automatically for workers on an HDHP, but you can also open one on your own at any time during the year you are covered by an HDHP.

Key Takeaways

  • You must be enrolled in an HDHP to open an HSA; check your health plan documents or call your insurer to confirm your plan qualifies.
  • You can open an HSA at a bank, credit union, brokerage firm, or through your employer's benefits administrator.
  • You will need your Social Security number, proof of HDHP coverage, and an initial deposit (amounts vary by provider, often $0 to $25).
  • If your employer offers payroll deduction, that is usually the fastest way to fund an HSA because contributions come out before taxes.
  • You can open an HSA any time you are covered by an HDHP, not just during open enrollment.

Confirm your health plan is an HDHP

Before you open an HSA, you must verify that your health insurance plan meets the IRS definition of a high-deductible health plan. The IRS sets minimum deductible amounts each year — for 2024, an HDHP must have a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. Your plan documents will state the deductible amount clearly.

Call your health insurance company or log into your plan's website and look for the Summary of Benefits and Coverage document or your plan's coverage details. If your deductible meets the minimum and you have no other health coverage (except certain exceptions like dental or vision), your plan qualifies. If you are unsure, ask your insurer directly: "Does my plan may have access to as a high-deductible health plan for HSA purposes?" They will give you a yes or no answer.

Choose where to open your HSA

You can open an HSA at many types of financial institutions. Banks and credit unions offer HSAs as savings accounts, often with a debit card for easy spending on medical expenses. Brokerage firms like Fidelity, Vanguard, and Charles Schwab offer HSAs that let you invest the money in stocks and mutual funds, which can grow faster over time but carries more risk. Insurance companies and third-party HSA administrators also offer accounts.

Compare a few providers on these points: monthly fees (many charge $0 to $5), minimum balance requirements, debit card availability, investment options if you want them, and customer service hours. Some employers partner with a specific HSA provider and offer payroll deduction only through that provider, so check your benefits materials first. If your employer does not offer one, you are free to choose any provider.

Gather the documents and information you will need

Have these items ready before you start the application:

  • Your Social Security number
  • Proof that you are enrolled in an HDHP — this is usually a letter from your health plan, a benefits summary from your employer, or a screenshot of your plan details from your insurer's website
  • Your driver's license or state ID
  • A bank account or debit card for your initial deposit (if required)
  • Your employer's name and benefits administrator contact information (if you are using payroll deduction)

Some providers ask you to upload documents directly in their application; others accept them by email or mail. The fastest route is usually uploading a PDF of your health plan's coverage details or a benefits letter from your employer.

Open the account online or in person

Most HSA providers let you open an account online in 15 to 30 minutes. Go to the provider's website, click "Open an HSA" or "New Account", and fill in your personal information, Social Security number, and employment details. You will be asked to confirm your HDHP coverage — some providers verify this automatically with your health plan, while others ask you to upload a document.

Once your application is submitted, the provider will review it, usually within one to three business days. You will receive an email confirming your account is open and providing your account number and login credentials. If you opened the account in person at a bank or credit union, you can often start using it the same day.

Fund your HSA through payroll or direct deposit

If your employer offers payroll deduction, this is the easiest way to fund your HSA. Your contributions come out of your paycheck before taxes are calculated, which lowers your taxable income. Ask your employer's benefits administrator or HR department for the payroll deduction form, fill it out with the amount you want to contribute each pay period, and submit it. The money will appear in your HSA within one to two pay cycles.

If you do not have payroll deduction, you can fund your HSA by transferring money from your bank account. Log into your HSA provider's website, select "Add Funds" or "Transfer Money", and follow the prompts to link your bank account. This usually takes one to three business days to complete. You can also make a one-time deposit by check or in person at a bank branch if your provider accepts it.

The IRS sets annual contribution limits — for 2024, you can contribute up to $4,150 for individual coverage or $8,300 for family coverage. If you are 55 or older, you can add an extra $1,000 per year. You do not have to contribute the full amount; you can contribute any amount up to the limit, and you can change your contribution amount at any time.

Understand what happens after you open your account

Once your HSA is open and funded, you can use the debit card (if your provider issued one) to pay for may have access to medical expenses at pharmacies, doctor's offices, and hospitals. Keep your receipts — the IRS requires you to have documentation if you are ever audited. You can also withdraw money to reimburse yourself for past medical expenses, as long as you have receipts.

Your HSA provider will send you an annual statement showing all deposits, withdrawals, and interest earned. You will also receive a Form 1099-SA at tax time if you made any withdrawals. Keep these documents for your records. If you change jobs or health plans, your HSA stays with you — it does not belong to your employer, so you can take it to a new provider if you want.

Frequently Asked Questions

Can I open an HSA if my employer does not offer one?

Yes. You can open an HSA at any bank, credit union, or brokerage firm that offers them, as long as you are enrolled in an HDHP. You will not have payroll deduction, so you will fund it by transferring money from your bank account instead. The contribution limits and tax benefits are the same.

What if I open an HSA but then switch to a health plan that is not an HDHP?

You can keep the HSA and the money in it, but you cannot make new contributions once you are no longer on an HDHP. You can still withdraw money for may have access to medical expenses at any time. If you switch back to an HDHP later, you can resume contributions.

Do I have to open an HSA in the same year I enroll in an HDHP?

No. You can open an HSA at any point during the year you are covered by an HDHP. However, if you want to make contributions for that year, you must open it by December 31. If you open it in January of the following year, you can only contribute for the new year.

What is the minimum amount I need to deposit to open an HSA?

This varies by provider. Some require no minimum deposit; others ask for $25 to $100 to open the account. Check the provider's website or call them before you apply to find out their requirement.

Can I have more than one HSA?

You can have accounts at multiple providers, but your total contributions across all accounts cannot exceed the annual IRS limit. If you have two HSAs and contribute to both, you must track the total to make sure you do not go over the limit. Most people keep one HSA to avoid confusion.
