In this video I break down a new IRS tax rule that starts in tax year 2026 (meaning you’ll feel it when you file taxes in 2027). The big change: the ACA premium tax credit repayment cap is being removed for ALL income levels. Before, a lot of people had a cap on how much they had to pay back if their income ended up higher than what they estimated on their Marketplace application. Starting in 2026, that safety net is gone—so if your income estimate is off, you could owe back a big lump sum. I walk you through the exact way this works using a Marketplace quote example. I show how someone estimating $30,000 could get about $451/month in credits, but if they actually made $50,000 they might have only qualified for around $191/month—leaving a $260/month difference. Multiply that by 12 months and you’re looking at about $3,120 owed back at tax time. The takeaway is simple: your application income needs to be as close as possible to your real income, and your tax household needs to match your Marketplace household so you don’t create tax trouble.
