Federal income tax filing deadline for individuals.
2025-04-15
This is the federal income tax filing deadline for individuals.
Deadline for applying for a six-month extension.
Deadline to make IRA and HSA contributions for 2024.
Deadline for the first quarter of 2025 (January 1 – March 31) estimated tax payment.
The IRS requires self-employed people and business owners to estimate their income for the year, figure out how much tax they’ll pay to the IRS for 2025, and make the first of 4 payments to the IRS by April 15.
Use IRS Form 1040-ES to when making estimated payments.
IRS Publication 505 is often also helpful because it offers guidance on how to calculate estimated tax.
If you overestimated your financial performance for 2025 and later realize you paid excess tax, you can apply for a refund or set the amount off against your 2026 quarterly tax payments.
