The short answer
If you don't take action during open enrollment, the Marketplace usually auto-renews your plan for the next year. That sounds convenient, but it can quietly cost you: your plan's premium may have risen, its benefits may have changed, and your subsidy is recalculated using last year's information, which may no longer be accurate. Auto-renewal is a fallback, not a strategy.
The better move is to actively review and re-shop each year, even if you end up keeping the same plan.
Why auto-renewal can cost you
Plans change every year — premiums, deductibles, networks, and drug lists all shift. A plan that was a great deal last year may not be this year, and a cheaper or better-fitting plan may now be available. Meanwhile, if your income or household changed, an outdated subsidy could leave you underpaid (owing at tax time) or overpaying now. Our guide to ACA open enrollment covers reviewing your options.
So auto-renewal can lock in a worse plan and a stale subsidy without you realizing it.
What to do each year
During open enrollment, log in, update your income and household details so your subsidy is accurate, and compare your current plan against the new options for the year. Check that your doctors and drugs are still covered well. If your plan is still best, keep it deliberately; if not, switch. Our ACA overview explains how to compare.
A few minutes of active review each year can save real money and prevent a tax-time surprise.
Frequently Asked Questions
Does my ACA plan renew automatically?
Usually yes, if you take no action during open enrollment. But auto-renewal can carry a higher premium, changed benefits, and an outdated subsidy, so it's worth reviewing.
Why should I re-shop my Marketplace plan each year?
Plans change premiums, networks, and drug lists yearly, and your income or household may have changed. Reviewing ensures you have the best plan and an accurate subsidy.
What should I update at open enrollment?
Your income and household details, so your subsidy is accurate, and confirm your doctors and drugs are still well covered before keeping or switching plans.
