Does a tax extension give you more time to pay?
Asked about 1,320 times a month, and the volume climbs every year as October approaches. The people asking have already filed for an extension and are working out what they actually bought with it, usually with the October deadline close enough to matter.
The extension is the most misunderstood form in the individual filing season, and the misunderstanding is expensive rather than merely academic. It is filed by people who are short of time, and read by those same people as though it were also filed by people who are short of money.
October 15 is four weeks away as this is posted, which is the point in the year when the question stops being theoretical. Anyone who filed for an extension in April and has not looked at it since is about to find out which of the two problems it actually solved.

No. It gives you more time to file, and nothing more. The IRS states it in one line on its own extension page: the extension is only for filing your return.
What you get is the date. Filing for an extension gives you until October 15 to file without penalties. What you do not get is any movement on the payment deadline, which stayed in April. If you owed money then, you have owed it since then.
The cost of the misunderstanding is specific rather than vague. The failure to pay penalty is 0.5% of the unpaid taxes for each month or part of a month the tax remains unpaid, and it will not exceed 25% of your unpaid taxes. Note the phrase part of a month: filing on October 16 rather than October 15 does not cost you a fraction of a month, it costs you the whole one. Interest runs on top of that separately.
The practical consequence people miss is that an extension is still worth filing even when you cannot pay. The failure to file penalty is much larger than the failure to pay penalty, so filing on time and paying late is a considerably cheaper mistake than doing neither. Pay whatever you can against the balance now, because the 0.5% is charged on what remains unpaid, not on what you originally owed.
If you are holding a US company and the numbers are not finished, the sequence that works is to estimate, pay the estimate, and file properly by October 15. An estimate that turns out slightly high costs you nothing but the wait for a refund. An estimate skipped entirely accrues at half a percent a month until it is settled.
