Will the irs be accepting taxes all weekend

[SteamTrain]

I suspect Probably not.....but we can't know their testing schedule.....thjey don't officially start until Monday 23 January.  And even then, they may decide to delay further if they've found issues with their tests last week.

One year they found a major fix to deal with that delayed their expected startup.

the start day of the 23rd is after this weekend.
