3. State Tax Rate (if applicable) - Some states tax HSA contributions (CA, NJ)

4. Payroll Tax Savings - If contributing via payroll (7.65% FICA tax savings)

How It Works: Triple Tax Advantage

HSAs offer three layers of tax savings:

1. Tax-Deductible Contributions - Reduce taxable income (like a Traditional IRA)

2. Tax-Free Growth - No capital gains or dividend taxes

3. Tax-Free Withdrawals - For qualified medical expenses

Tax Savings Formula

$$\text{Annual Tax Savings}=\text{Contribution}\times (\text{Federal Tax \%}+\text{State Tax \%}+\text{7.65\% if payroll deduction})$$

Future Value Formula (If Invested)

$$FV=\text{Contribution}\times {(1+\frac{r}{n})}^{n\times t}$$

Where:

• $r$ = annual growth rate

• $n$ = compounding periods per year

• $t$ = years invested

Example Calculation

Parameter	Value
Annual Contribution	$3,850 (individual)
Federal Tax Bracket	24%
State Tax	5% (no HSA deduction)
Payroll Deduction	Yes (saves 7.65% FICA)
Investment Growth	6% annually
Time Horizon	20 years

1. Immediate Tax Savings:

$$\mathrm{\$}3,850\times (24\mathrm{\%}+0\mathrm{\%}+7.65\mathrm{\%})=\mathrm{\$}3,850\times 31.65\mathrm{\%}=\ast \ast \mathrm{\$}1,218\mathrm{/}year\ast \ast$$

2. Future Value (Invested):

$$\mathrm{\$}3,850\times (1.06{)}^{20}=\ast \ast \mathrm{\$}12,348\ast \ast$$

Total Benefit:

• $1,218 annual tax savings

• $12,348 tax-free growth in 20 years

• $0 taxes on qualified withdrawals
