Guidelines for Year End Giving

Make your gift count in 2023

The end of the year is a time many are inspired to make charitable gifts and we thank you for your interest in preserving and protecting Glacier.

If you choose to give to the Glacier Conservancy before the end of December, please use these helpful tips to make sure your gift counts in the 2023 tax year.

The Glacier National Park Conservancy’s federal tax ID # is 56-2579734. The Conservancy is tax-exempt under section 501(c)(3) of the IRS code.

What are the deadlines for gifts to be counted in 2023?


Checks should be dated for 2023, made out to Glacier National Park Conservancy, and mailed to:

Glacier National Park Conservancy
P.O. Box 2749
Columbia Falls, MT 59912


Checks via U.S. Postal Service:

Your check mailed via USPS must be postmarked by December 31, 2023 to count as a 2023 gift. The postmark date is used as your gift date. Please note December 31st is a Sunday this year and many post offices will be closed.


Checks via a private carrier (UPS, FedEx, etc.):

Checks sent by other carriers must be received by someone at Glacier Conservancy by December 29, 2023 (the office will be closed December 30th and 31st). Unlike gifts we receive by USPS, gift dates for gifts sent by private carriers are based on when they are received by the Conservancy. 


Delivery address for UPS/FedEx:

Glacier National Park Conservancy
402 9th Street West
Columbia Falls, MT 59912

Wire Transfers

Wires need to be successfully deposited in the Conservancy’s wire account by 11:59 p.m. Pacific Time on December 29, 2023. We recommend that wire transfer requests be made prior to the holidays, and, at the latest, by Tuesday, December 26.

Please contact Stacy Dubuc at (406) 892-3250 or to learn more about donating via wire transfer.

Credit cards

Credit card gifts made online:

Online gifts must be made by 11:59 p.m. Pacific Time on December 31, 2023.


Credit card gifts by phone or mail:

All credit card gift information must be received by 5 p.m. Mountain Time on December 29, 2023. Any credit card gift received after that time may be designated as a 2024 gift. Per IRS rules, we cannot account for a credit card gift until the charge is made, and a 5 p.m. deadline ensures we can charge your card before close of business that day.


Never send your credit card information via email.


Stock gift and mutual fund transfers in December can take several weeks to transfer due to increased activity. Please make your transfer requests in early December to ensure completion by Friday, December 29, 2023. (December 30 and 31 fall on the weekend, so electronic transfers will not happen those days.)


Stock gifts must be received in the Conservancy’s brokerage account by close of business (6 p.m. Eastern Time) on December 29, 2023, in order to qualify as a charitable donation this tax year. During the holidays, brokerage firms do not guarantee transfer in 2023 for requests made after certain dates. Please confirm 2023 transfer cut-off dates with your broker.


Please contact Stacy Dubuc at (406) 892-3250 or to learn more about donating with stock.
