A tax extension grants6 more months to file your return (until Oct. 15), but it is not an extension to pay. If you owe taxes and get an extension, you must still pay the estimated amount due by the April deadline to avoid interest and failure-to-pay penalties, although you will avoid the harsher failure-to-file penalty.

Can I get an extension on my taxes if I owe money?

How long does the IRS give you to pay owed taxes?

The IRS gives you options for paying back taxes, including a short-term plan (up to 180 days) with no fee but accruing interest/penalties, or a long-term installment agreement (up to 10 years) for monthly payments, which usually has setup fees and less penalty rates if you filed on time. You can apply online at IRS.gov/paymentplan for amounts under certain thresholds (e.g., <$100k for short-term, <$50k for long-term), or by mail/phone if needed.

What happens if I file taxes after October 15th?

If you file taxes after the October 15 extension deadline, the IRS will assess penalties and interest, primarily a failure-to-file penalty (5% per month, max 25%), plus a separate failure-to-pay penalty (0.5% per month) and daily interest on the unpaid taxes, though you can request penalty abatement for reasonable cause like natural disasters. The October deadline is for filing, not paying; if you owe, payment was due in April, so you'll likely face both penalties and interest until you file and pay, but you won't be penalized if you're due a refund. 

Is there a downside to filing a tax extension?

These penalties can add up to 25% of the tax due. However, if you file a tax extension and miss the extended deadline, you are subject to the penalty fee. Bear in mind that filing an extension when you owe taxes gives you more time to file, but payment is still due at the tax filing deadline.
