HSA vs FSA: Which Tax-Free Account Is Better?

Both HSAs and FSAs let you pay for healthcare expenses with pre-tax dollars, but they work very differently. This guide helps you understand which account saves you the most money.

Overview

HSA (Health Savings Account)

  • Requires HDHP (high-deductible health plan)
  • You own the account
  • Funds roll over forever
  • Can invest for growth
  • Triple tax advantage

FSA (Flexible Spending Account)

  • Any health plan qualifies
  • Employer owns the account
  • Use it or lose it (mostly)
  • Cannot invest
  • Tax-free contributions only

Side-by-Side Comparison

We have not published the 2027 figure yet, so this is the 2026 figure.

HDHP Requirements for HSA Eligibility (2027)

  • Minimum deductible: $1,750 (individual) / $3,500 (family)
  • Maximum out-of-pocket: $8,700 (individual) / $17,400 (family)
Bronze Plans: From 2026 every Bronze and Minimum Coverage plan qualifies for an HSA, whatever its deductible and out-of-pocket maximum, making them a good pairing for tax savings.

Which Should You Choose?

HSA Is Better If:
  • You can handle a high-deductible plan
  • You want long-term savings
  • You're healthy and don't use much care
  • You want to invest for retirement
  • You want portability between jobs
FSA Is Better If:
  • You have predictable healthcare costs
  • You can't afford an HDHP
  • You need money upfront (full amount day 1)
  • Your employer doesn't offer HDHP
  • You'll use the full amount each year
Best of Both Worlds: If you have an HSA-eligible HDHP, you can also have a Limited Purpose FSA for dental and vision expenses only.
