Is 17 February an actual US tax due date?

No. 17 February is a timely reminder date, not the US due date. The federal filing date is the April 15 deadline for most taxpayers. Some areas get disaster‑relief extensions. Filers can also request an extension to mid‑October, but any tax owed still must be paid by April 15 to avoid extra charges.

What are the main IRS late penalties?

If you miss the filing date, the failure‑to‑file penalty is 5% of unpaid tax per month, up to 25%. If you do not pay on time, the failure‑to‑pay penalty is 0.5% per month, plus daily interest. Filing on time, even without full payment, usually reduces total charges and limits compounding.

Can refunds really be bigger this year?

Yes, some filers may see larger refunds due to new tax deductions, inflation‑indexed brackets, and higher standard deductions. Credits can also change. Results vary by income, filing status, and state rules. Filing early with e‑file and direct deposit can speed any refund, which may influence spending in late Q1 and Q2.

Why should UK investors care about a US tax deadline?

Refund timing affects US discretionary spending and can sway retail earnings commentary. That can move share prices and risk appetite globally. If refunds arrive in a tight window, we may see short bursts in sales. UK investors should watch US retail data, earnings calls, and pound‑dollar moves for confirmation.
