When can HSA contributions be made? Is there a deadline for contributions to an HSA for a taxable year?

For an established HSA, contributions for the taxable year can be made in one or more payments at any time after the year has begun and prior to the individual’s deadline (without extensions) for filing the eligible individual’s federal income tax return for that year. For most taxpayers, this is April 15 of the year following the year for which contributions are made.
