Depending on your tax situation and what kind of filer you are, there are different tax dates to be aware of. Below are the important tax dates and deadlines for individual filers, including those who are retired, an employee, or self-employed.
For self-employed individuals or those with other income without tax withholding.
The IRS has not yet announced an official tax year 2025 start date, but the agency typically starts accepting and processing income tax returns in late January.
Employers must send W-2 tax forms no later than this date (you still might receive yours in early February).
This is also the deadline to send certain 1099 tax forms, including Form 1099-NEC, which reports self-employment income from side hustles or freelance work. You might also receive a Form 1099-MISC if you received income from interest or dividends, rents, royalties, or prize winnings.
This applies if you claim an exemption from your employer withholding taxes from your paycheck on your Form W-4. To remain exempt from withholding, you must give your employer a new Form W-4 by this date every year.
From your retirement account if you turned 73 during the previous year (2025).
