Final answer:
No, married taxpayers who file a joint return cannot switch to separate returns after the filing due date.
Step-by-step explanation:
No, married taxpayers who file a joint return cannot switch to separate returns after the filing due date. Once a joint return is filed, it cannot be changed to separate returns for that year.
This is because the decision to file a joint return is a permanent choice for that tax year.
The Internal Revenue Service (IRS) requires married taxpayers to carefully consider the advantages and disadvantages of filing jointly before making their tax return decision.
Filing jointly typically offers more tax benefits, such as higher standard deductions and lower tax rates.
However, it's important to consult a tax professional or refer to IRS guidelines for specific details and exceptions.
