The Internal Revenue Service of the United States (IRS) presented a proposal on Wednesday for new rules regarding subsidies for Obamacare, which outlines how taxpayers who receive federal assistance to pay for their health insurance should repay any excess funds received.
The initiative, announced by the Department of the Treasury and the IRS, implements changes to the Premium Tax Credit (PTC) for health insurance premiums, according to the official statement from the tax authorities. The document is a regulatory proposal and not a final rule.
The main consequence for the beneficiaries is that those who receive more subsidies than they are actually entitled to will have to return the entire difference, without the reimbursement limit that previously protected certain taxpayers.
However, there is an important distinction: this obligation was not approved now. The removal of the limit was established in the federal law known as One Big Beautiful Bill Act, enacted on July 4, 2025, and it applies to fiscal years beginning after December 31 of that year.
What the IRS presented this Wednesday is a proposal to update its regulations to reflect that legal change, along with other provisions regarding eligibility and verification of the assistance.
The official text of the proposal REG-101576-26 states that when the subsidy advances exceed the allowed tax credit, the entire excess will increase the tax liability for the corresponding coverage year.
To understand how it works, one must distinguish between the final subsidy and the advances received throughout the year.
When a person applies for health insurance through the Obamacare marketplace, they may receive financial assistance calculated based on the income their household expects to earn. This amount is applied monthly to reduce the cost of the insurance premium.
These payments are known as APTC, which stands for Premium Tax Credit in English. The PTC, for its part, is the tax credit that ultimately corresponds to the taxpayer based on their income and other circumstances throughout the year.
When filing the federal tax return, both amounts must be compared using a process called reconciliation.
If the taxpayer received less assistance than they were entitled to, they may have the right to claim the difference. However, if they received advances greater than the final credit, they will need to repay the excess.
This does not mean that all people with Obamacare must return their subsidies or that they must necessarily repay all the assistance received. The repayment is limited to the amount that exceeds the tax credit to which they were actually entitled.
The difference may arise, for example, when a person estimates that they will have certain income when applying for insurance, but ends up earning more money during the year. Changes in family composition or other circumstances that affect eligibility may also play a role.
Until the fiscal year 2025, there were limits that, depending on income and family situation, could reduce the amount that had to be repaid.
Starting from the 2026 fiscal year, those limits will disappear. Therefore, if a person received advances exceeding the credit that ultimately applies to them, they will need to repay the entire difference, even if they initially calculated their income in good faith.
An income estimate that does not match the actual amount earned does not, by itself, constitute fraud. Differences can arise from salary increases, job changes, overtime, or other economic variations throughout the year.
To carry out the reconciliation, beneficiaries must use the form 1095-A, which contains information about the insurance premiums and the advances applied to their coverage.
With this information, the Form 8962 is completed, which is used to calculate the final tax credit and determine if there is an additional amount in favor of the taxpayer or an excess that must be reimbursed.
The new obligations for the fiscal year 2026 will generally be reflected in the declarations for that year submitted in 2027. It is important not to confuse the year in which the coverage was received with the date the declaration is submitted.
The IRS proposal also addresses eligibility requirements and mechanisms to verify the information used when applying for subsidies.
According to the notice available in the Federal Register, the document was under public inspection on October 14 and was scheduled for publication on the 15th.
Some of the additional verifications included in the legal reforms correspond to fiscal years starting after December 31, 2027, so not all the changes included in the proposal will take effect at the same time.
For Cubans and other immigrants residing in the United States, the modifications must be analyzed taking into account both tax obligations and the requirements to receive assistance.
In this regard, a guide on enrollment in Obamacare for 2027 explained that certain immigration categories will retain access to subsidies, while others will face restrictions.
Among the categories that may continue to meet the requirements are legal permanent residents and certain individuals classified as Cuban or Haitian entrants (Cubans or Haitians with a special entry immigration category), provided they meet the other conditions of the program.
However, being born in Cuba does not automatically mean belonging to that immigration category, nor do the new restrictions imply that all immigrants will lose their health insurance.
The tax announcement also coincides with other federal actions regarding Obamacare assistance. This Wednesday, it was revealed that the United States withdrew subsidies from 189,000 people after detecting duplicate coverage records or records belonging to deceased beneficiaries.
However, that administrative review is different from the annual reconciliation of the tax credit. The withdrawal of assistance due to eligibility issues or records does not automatically equate to an obligation to repay advances when filing taxes.
The Department of the Treasury asserts that the reforms aim to strengthen controls over subsidies and prevent improper payments, although the existence of a discrepancy between the advances received and the final credit does not, in itself, demonstrate that a taxpayer has committed a violation.
For those receiving monthly assistance from Obamacare, the most important thing is to carefully estimate household income, update information when circumstances change, and keep the necessary documents for tax declaration.
The proposal presented on October 14 must follow the regulatory procedure before it becomes final. However, the removal of the old repayment limit is already established by law for the fiscal year 2026.
As a result, beneficiaries who receive advances exceeding the tax credit to which they are truly entitled must return the entire difference when they conduct their tax reconciliation, without the protections that previously limited the refund for certain income levels.
