It’s common for income to change throughout the year, particularly if you are self-employed, have a seasonal job, or more than one job. To get the most accurate tax credit amount, you should let the Health Connector know if you have any income changes during the year, as they happen.
If you expect your income to go up during the year, you may want to consider changing the amount of tax credit that you apply to your monthly premiums, so that you take less than the full amount available to you. If you use your tax credit during the year and your actual income is over the amount that makes you eligible, you may need to pay back some or all of the credit. You always have the option of waiting until you file your taxes next year to take the credit on your tax return, instead of applying it to your premiums in advance. This may make sense for you if you aren’t sure what your income will be for the year, and are concerned about having to pay money back at tax time.
