We sold a vacation home is 2024 and had a large capital gain. We paid the estimated taxes based on a long term rate of 15%. When filling out our taxes this year, it looks like the capital gain was filled out properly but didn't seem to be at the 15% rate. It looks to have been added to our overall taxable income which is at a higher rate. Does the long term capital gain push us to another higher tax bracket? From what I read, it shouldnt, but TT seems to be doing that.

I modeled our taxes without the capital gain and est tax payment and it was as expected. Once the capital was added in it made a big difference and an amount due. Am i doing something wrong?

Form 1040 does not show long-term capital gain separately from ordinary income. To see the amount of long-term capital gain you have to look at Schedule D. The tax calculation takes into account the different types of income and applies the appropriate rates. Since you have long-term capital gain your tax is probably calculated using the Qualified Dividends and Capital Gain Tax Worksheet, or possibly the Schedule D Tax Worksheet. The worksheet will show the tax rate that is being applied to various amounts of income.

Even if the long-term capital gain is taxed at 15%, the total tax on your tax return might increase by more than 15% of the gain. That can happen because adding income to a tax return can have side effects besides the direct tax on the added income. The increase in income could reduce or eliminate various deductions or credits that are not related to the income that was added, but that have income-based limits or phase-outs. If you received Social Security benefits it could make more of your Social Security taxable. You have to compare your entire Form 1040 line by line before and after adding the interest to see what else is changing besides the capital gain. If there's a change in an amount that comes from another form or schedule, you have to look at that form or schedule to see what's happening.

Ok, so I tracked it down to form 8960. Since the capital gain pushed us over the 250,000 filing status threshold, there is another 3.8 % tax on the the capital gain as shown on line 17 of form 8960. So we’re paying almost 11K more in tax as a result. Does this make sense that this shows up for a capital gain on the sale of a second home?

Yes, it makes sense. The Net Investment Income Tax applies to just about any non-business capital gain. The instructions for Form 8960 say "net investment income includes net gain (to the extent taken into account in computing taxable income) attributable to the disposition of property other than property held in a trade or business ..."
