Does that €750M threshold apply to the global company or just operations in a specific country? Like if a company makes €800M worldwide but only €100M in France, would it still be subject to the minimum tax in France?

The €750M threshold applies to global consolidated revenue of the multinational group, not the revenue in each specific country. So in your example, a company with €800M worldwide revenue would be subject to the minimum tax rules even if they only had €100M in France. This is actually one of the key points of the agreement - it's designed to capture large multinationals that might have relatively small operations spread across many countries. The threshold was set to target the largest 10-15% of multinational enterprises while excluding smaller companies that would face disproportionate compliance burdens.

That's a really good point. Do you think there's any chance the OECD will modify the agreement to address these concerns? Or are developing nations just going to be left behind?

I'm guessing it's for system maintenance and updates. Most big financial systems have a daily maintenance window - banks often do similar things in the middle of the night. 11:45pm-midnight ET probably affects the fewest users across all US time zones while still being overnight for the IRS east coast operations.

That makes sense about the maintenance window. Just seems poorly timed during tax season when so many of us are burning the midnight oil trying to get things filed. They should at least put a more visible warning on the site about it!

Yes, absolutely save the payment confirmation as proof. Take a screenshot or save the PDF they email you. While the IRS system should automatically register your extension when you make that payment, having documentation is crucial if there's ever a question about whether you filed for an extension on time. I recommend saving it in multiple places (email, cloud storage, etc.) just to be safe. I've had clients who needed this proof years later during audits.

Thanks for confirming! I just did the $1 payment and saved both a screenshot and the PDF they sent. Feeling much better now knowing I have solid proof of the extension filing. I need the extra time to sort through some investment documents that still haven't arrived.

Good call - we're actually planning to move in March. What's the best way to update our address with the IRS? Is that something we should do before filing our 2024 taxes?

You should definitely update your address before you move. The easiest way is to file Form 8822 (Change of Address) directly with the IRS. You can download it from IRS.gov and mail it in. While putting your new address on your 2024 return will eventually update their records, that could take months to process, and you don't want to risk missing any correspondence in the meantime. If you're moving in March, I'd recommend sending the Form 8822 about 2-3 weeks before your move. Also make sure you file a change of address with USPS so they forward any IRS mail that might still go to your old address during the transition period.

The IRS is actually running on systems from the 1960s in some departments! I worked with a government contractor who helped maintain their systems and it's SCARY how outdated some of their infrastructure is. They're still using programming languages most developers have never even heard of.

Thanks for mentioning this! I've definitely filed and paid on time for the last several years. How do I request this abatement? Is it something I ask for when setting up the payment plan, or is it a separate process?

You can request it when you call to set up your payment plan. Just specifically mention that you'd like to request a "First Time Penalty Abatement" based on your history of compliance. The agent should be able to check your eligibility on the spot. If they approve it, they'll remove the failure-to-pay penalties, though interest will still apply to your balance. If you set up your payment plan online, you'll need to call separately to request the abatement. Make sure to do this sooner rather than later - it's easier to get penalties removed before you've paid them than to get a refund afterward.

This is super important! My brother had to pay penalties two years in a row because he didn't adjust his withholding after the first time he owed a lot. The second time, the IRS was way less forgiving about waiving penalties.

Thanks for mentioning the penalties! I wasn't aware of that distinction with extensions. Do you know roughly how much those penalties typically run? I'm worried now because I definitely didn't pay anything back in April when I filed the extension.

The failure-to-pay penalty is usually about 0.5% of your unpaid taxes per month, with a maximum of 25%. There's also interest that compounds daily at the federal short-term rate plus 3%. It's not catastrophic for most people with simple returns, especially if you're due a refund (in which case there's no penalty at all). But if you owe a significant amount, it can add up. Most tax software will calculate this automatically once you input when you're filing.

VITA is amazing, but most sites are only operational during the regular tax season (Jan-Apr). It can be hard to find VITA services for prior year returns in October.
