What the IRS is Up To

How the USPS Postmark Update Affects Your Tax Return

The USPS now applies postmarks at processing facilities rather than at local post offices. The mail may be received by the processing center on a different day than it was dropped off, which could affect paper tax returns, extensions, or payments. Because the IRS uses postmark dates to determine timeliness, this could trigger penalties, interest, or rejected filings. Electronic filing remains the safest option whenever possible.

IRS Releases Initial Guidance on ‘Trump Accounts’

‘Trump Accounts’ are a new tax-advantaged savings program for children under the OBBBA. Contributions are not expected to start until July 2026, but taxpayers can elect to enroll using IRS Form 4547 when filing 2025 tax return. Families should monitor IRS guidance and consult their CPA or financial advisor to see if a Trump Account is right for their situation.
