When should a nonprofit send year-end receipts so donors can actually use them?

The rule: earlier of filing date or due date

The requirement is that a donor must have the written acknowledgment in hand by the earlier of the date they actually file their return or the due date for that return, including extensions. There is no fixed January deadline in the rules, which surprises people who assume year-end receipts are governed like tax forms from employers. The catch is in the word earlier. A donor who files in late January needs your acknowledgment before then, and a letter that arrives in February cannot be made contemporaneous by any amount of good intention.

This is why the practical target is the end of January for the bulk send, with individual gift receipts going out all year as gifts arrive. The year-end statement then serves as a consolidated backup for donors who did not keep every confirmation. Organizations that treat January statements as the only acknowledgment they send are betting that every donor files after the statement lands, and enough early filers exist that the bet is not worth making.

Which gifts belong in which year

Before you can send accurate statements, you need to close the year cleanly, and that means applying the gift-date rules consistently. A check mailed by the donor with a December postmark counts as a December gift even if it arrives in January, so hold the year open for the first week or so of January and check envelopes. A check that a donor hands you on January 3 dated December 30 is a January gift. Credit card contributions count on the date the charge is made, not when it settles or when you see it in your bank account.

Stock counts when the shares are delivered into your account, which can lag a donor's instruction by days, and a transfer initiated December 29 that lands January 4 is a January gift no matter how much the donor wanted otherwise. Pledges count only when paid. Online gifts made after midnight on December 31 in your processor's time zone belong to the new year. Write these rules down, apply them the same way every year, and be ready to explain them kindly to the donor whose December intention became a January fact.

Building the January schedule

Working backward from an end-of-January send, the first week of the month goes to closing the year: processing mail postmarked in December, reconciling the payment processor and the bank, matching stock transfers and IRA custodian checks to donors, and correcting duplicate records. The second week is for generating draft statements and reviewing them, with the largest gifts and any event payments getting a careful read. The third week is for sending, with a small test batch first to catch template problems before a thousand donors see them. Related: Handling Year End at a Small Nonprofit

That leaves a buffer for the inevitable: bounced emails, returned mail, and donors who write back with a question or a correction. Building a week of slack into the schedule is the difference between handling those calmly and scrambling. If your organization has a significant number of donors who prefer paper, print and mail a few days before the email send, since mail takes longer. And send a short internal note to program staff and the front desk about what went out, so that whoever answers the phone knows what a donor is holding.

What to do when you are late

Sometimes January gets away from a small team, and statements go out in mid-February. That is not a catastrophe. Most donors have not filed yet, and for those who gave less than $250 in any single gift, the acknowledgment was never strictly required. Send the statements as soon as they are ready, dated honestly, and include a brief line apologizing for the delay. Donors who have already filed can take the statement to their preparer, who will decide whether anything needs to change.

What you should not do is date the letters back to January, or skip sending because it feels too late. The acknowledgment still has value as a record, and donors notice which organizations send one and which do not. Then fix the process: figure out which week slipped and why, and move that task earlier next year. Most timing failures trace to reconciliation, because the data was not ready when the letters were supposed to go, and that is a solvable problem with a checklist that starts in December.
