Frequently Asked Questions

What happens if I miss a tax deadline?

+

Missing a tax deadline can result in penalties and interest charges. The IRS typically charges a failure-to-file penalty of 5% per month (up to 25%) and a failure-to-pay penalty of 0.5% per month. It's best to file for an extension if you need more time.

How do I file for a tax extension?

+

You can file for an automatic 6-month extension using Form 4868 for individuals or Form 7004 for businesses. The extension must be filed by the original deadline. Note that an extension to file is not an extension to pay - you still need to estimate and pay any taxes owed by the original deadline.

Who needs to make estimated tax payments?

+

Self-employed individuals, freelancers, independent contractors, and anyone who doesn't have taxes withheld from their income typically need to make quarterly estimated tax payments. If you expect to owe $1,000 or more in taxes, you should make estimated payments.

Can I still contribute to my IRA after December 31?

+

Yes! You have until the tax filing deadline (typically April 15) to make IRA contributions that count toward the previous tax year. This gives you extra time to maximize your retirement savings and potentially reduce your tax liability.

What if a deadline falls on a weekend or holiday?

+

When a tax deadline falls on a Saturday, Sunday, or legal holiday, the deadline is automatically moved to the next business day. For example, if April 15 falls on a Saturday, the deadline becomes Monday, April 17.

How can I get deadline reminders?

+

You can subscribe to our email reminder service to receive notifications before important tax deadlines. We'll send you timely reminders so you never miss a filing date. You can also download our tax calendar PDF to keep track of all important dates.
