Individuals and businesses often face tight deadlines when it comes to filing taxes. However, there are options available to extend the filing deadline for those who need more time to gather information or prepare their returns.

For individuals, requesting an automatic 6-month extension can be done electronically through online filing services or by filing Form 4868. This extends the filing date to October 15th, 2025. Similarly, businesses can apply for a 6-month extension using Form 7004, with due dates varying depending on the type of company filed.

It's important to note that these extension forms do not extend the due date for the initial taxes owed, but rather provide additional time for filing. To avoid penalties and interest, it is recommended to pay the estimated taxes owed along with the filing of the respective extension form.

By taking advantage of these extension options, individuals and businesses can ensure compliance with tax requirements while allowing for adequate time to prepare accurate returns.

Even with the most meticulously maintained financial records, errors can occasionally surface in tax filings. Should you need to revise your filing status, income, deductions, credits, or tax liability, you may find it necessary to amend your return. This process can be initiated using Form 1040-X and is typically undertaken after your initial return has been processed.

It's important to note that minor math errors do not necessitate an amended return, as the IRS will automatically rectify such mistakes. However, if you are seeking to claim a refund or tax credit from a previous year, you must submit Form 1040-X within 3 years following the date of your original return filing or within 2 years following the date of tax payment, whichever occurs later.

Keep records for 3 years from The date you filed your original tax return or 2 years from the date you paid the tax, whichever is later, if you're claiming a credit or refund after filing your return.

Keep records indefinitely if You haven't filed a tax return, or You've filed a fraudulent return.

Keep employment tax records for at least 4 years after the tax becomes due or is paid, whichever is later.
