How much is the Affordable Care Act penalty?

The penalty for not having health insurance (a.k.a. Shared Responsibility Payment) only applies to the months you didn't have health insurance.

For 2018, the penalty is either 2.5% of your taxable household income (up to the national average annual premium for a Marketplace Bronze plan) or $695/$347.50 per uninsured adult/child under 18 (up to a maximum of $2,085), whichever is greater.

If you tell us you didn't have health insurance coverage or only had it for part of 2018, we'll create Form 8965, calculate the penalty and also check to see if you qualify for a health coverage exemption.
