The business isn’t an excluded business. Generally, an excluded business means equipment leasing as defined, earlier, under Exception for equipment leasing by a closely held corporation , and any business involving the use, exploitation, sale, lease, or other disposition of master sound recordings, motion picture films, video tapes, or tangible or intangible assets associated with literary, artistic, musical, or similar properties.
Partnerships and S corporations aren’t subject to the rules for new grouping, addition to an existing grouping, or regrouping. Instead, they must comply with the disclosure instructions for grouping activities provided in their Form 1065, U.S. Return of Partnership Income, or Form 1120S, U.S. Income Tax Return for an S Corporation, whichever is applicable.
The real value of a building lies in the tenant. If you’re the tenant and you’re a good tenant, you might as well be the owner, otherwise, you’re giving that benefit away to someone else. A few years back we bought most of our buildings from other owners after renting from them for many years. Our approach to the building owners was, “We want to own our own offices, we are willing to pay you a fair price for the building, but if you won’t sell, we’ll buy somewhere else and move. 4/5 sold to us, the one that wouldn’t sell, we decided to buy a new office building and moved. Owning your own office is typically a very safe and very good investment if bought at a fair market value and assuming you are planning on staying put at least 5+ years. If you are trying to buy the office from your current landlord, I think a fair price is somewhere between the value of a vacant office building and the value of a stable physician occupied office with a long-term lease.
A former passive activity is an activity that was a passive activity in any earlier tax year, but isn’t a passive activity in the current tax year. You can deduct a prior year's unallowed loss from the activity up to the amount of your current year net income from the activity. Treat any remaining prior year unallowed loss like you treat any other passive loss.
You don’t have to be a big corporate executive to need an assistant. Filing, emailing, scheduling and organizing the results of your moneymaking ventures takes time. And that's time you don’t want to waste while building your passive income empire. Nor do you want to expend any more time and money training and paying a new employee than you need to. Instead, consider hiring a virtual assistant.
If you qualified as a real estate professional for 2017, report income or losses from rental real estate activities in which you materially participated as nonpassive income or losses, and complete line 43 of Schedule E (Form 1040). If you also have an unallowed loss from these activities from an earlier year when you didn’t qualify, see Treatment of former passive activities under Passive Activities, earlier.
Some investments, such as certain notes, T-class units of mutual funds and REITs, pay a mixture of income and a return of capital. A return of capital is not included in income in the year received; rather, it reduces the adjusted cost base of the investment and increases the capital gain (or decreases the capital loss) on the future disposition of the investment.

In fact, as I laid in bed one morning coming up with this post, I could really only think of one aspect of passive income that is worse than earned income. If you are a high earner, you can’t deduct real estate losses against your earned income unless you qualify as a “real estate professional,” which basically means you spend > 750 hours a year doing it. That’s it. The rest of the time, passive beats active.
When I purchase an existing online business, I look for cash flow over the past year and where the money comes from. I want the sources to be more passive so that it does not take a lot of my time. Also, typically I will make an offer that is 18 – 24 months of profit so that I know that I will get my money back within the next two years. I hope that helps!
