With the federal tax deadline extended to July 15 in response to COVID-19, there are several other key dates every taxpayer, business, and retirement account holder should mark on their calendar. From required minimum distribution (RMD) changes under the SECURE Act to deadlines for extensions and charitable donations, staying informed can help avoid penalties and simplify your planning.

A Traditional IRA lets you deduct contributions today but taxes withdrawals in retirement, with required distributions after age 70½. A Roth IRA flips this: you contribute after-tax dollars, but all qualified withdrawals—including growth—are tax-free, with no required distributions. The right choice depends on whether you prefer tax savings now or tax-free income later.
