alt Hacker News> They're only deferring the tax on $70-80K, correct?
Yes, if they sell normally. But usually capital gains tax is lower than that on the income so overall they're saving.
To be explicit: They use the $70-80K depreciation to offset their rental income (which often means they pay no tax on the income for that year and several years after). They'll pay it eventually when they sell, but at a (usually) lower tax rate.
There are tricks like 1031 exchange to avoid paying taxes when they sell, but I don't know how depreciation benefits factor in to those.
This is almost completely wrong.
First, depreciation on real property is about 27 years. 80k annual depreciation indicates a 2.2m purchase price.
Corporate capital gains don't get a special rate. They're taxed the same as regular corporate income. The 1031 like kind exchange is also very difficult to achieve as the bar is very high even under the Trump admin.
