It is never too early to start preparing for the April 15th tax deadline!
Here are a few helpful tips to keep in mind:

• File on Time: Even if you can't pay the full amount owed, file your return by the deadline to avoid the hefty failure-to-file penalty.
• File an Extension: If you need more time to file your return, you can request an automatic six-month extension using Form 4868 by the end of today. This pushes your filing deadline to October 15, but remember, it's not an extension to pay.
• Pay What You Can: Pay as much as possible to minimize interest and penalties on the remaining balance. The IRS offers various online payment options and payment plans.
• Owe a Refund? If the IRS owes you a refund, there's generally no penalty for filing late, but you could miss out on unclaimed credits if you wait too long.

Stay informed by visiting the official IRS website for accurate information and resources.
