Frequently Asked Questions

What are the 2024 HSA contribution limits?

For 2024, the HSA contribution limit is $4,150 for individual coverage and $8,300 for family coverage. If you're 55 or older, you can contribute an additional $1,000 catch-up contribution. These limits are adjusted annually for inflation.

What makes HSAs so tax-advantaged?

HSAs offer triple tax benefits: contributions are tax-deductible (or pre-tax through payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. After age 65, you can withdraw for any purpose (taxed as ordinary income), making HSAs retirement accounts with medical superpowers.

When should I do a Roth conversion?

Roth conversions make sense when: you expect higher tax rates in retirement, you're in a temporary low-income year, you want tax diversification, you have cash to pay the tax outside the IRA, or you want to leave tax-free money to heirs. Avoid conversions in high-income years.

How much tax will I pay on a Roth conversion?

The converted amount is added to your taxable income for the year and taxed at your marginal rate. A $50k conversion in the 24% bracket costs about $12k in federal tax. Large conversions can push you into higher brackets, so many people convert gradually over several years.
