Should I apply my refund to next year's return if my total deductions exceed my current estimated refund?

Applying your refund to your estimated taxes may be a good idea if:

• You want to get a head start on next year's tax liability paying estimated taxes,
• You reduce the burden of setting aside money to pay your estimated taxes.
• You can reduce underpayment penalties on next year's tax return, and
• It may help protect your refund from bankruptcy judgment.

Follow these steps:

• Down the left side of the screen, click on Federal.
• Across the top of the screen, click on Deductions & Credits.
• Scroll down to Estimates and other taxes paid.
• Click on Income Taxes Paid.
