Well this is concerning.

USPS shifts postmark policy that could impact your taxes.

The United States Postal Service quietly changed how it applies postmarks,
and that operational tweak could ripple straight into your tax bill. By shifting the postmark from the local counter to regional processing centers, the Postal Service has effectively shortened the practical window for taxpayers who rely on the mail to prove they paid on time.

This will also impact mail in voting.

1. But I believe you can walk an envelope into the building and request that they post mark it that day.

Could be wrong on this, but I believe I read that.

2. Same day Post mark

As of early 2026, the
USPS no longer guarantees same-day postmarks for mail dropped in blue collection boxes, as they are now processed based on the date they reach a sorting facility. To ensure a same-day postmark for tax or legal deadlines, you must bring items to a post office counter and request a manual postmark.

5. I couldn't say.

On my (Illinois) primary ballot it said to mail it at least a week before because they
don't postmark at the post office anymore. I won't be mailing mine anyway, I'll be
dropping it of at an early voting location that has a dropbox inside.

6. Pls see #2 above. To guarantee same day postmark, you must walk it inside to the counter & request it.

Fucking dejoy.

4. Maybe more should consider

filing online.

7. There was nothing 'quietly' about this. It was reported extensively

by both the USPS themselves, along with a whole raft of media.

And - if you're one of those people that is waiting until that last 12 hour window in order to 'mail' your tax return ...
Thinking you're probably familiar with the term 'penalty' already.

( and, yes - feel much the same about people that 'sit' on their mail-in ballot - until the last conceivable moment. )
