Thank you so much for the reply. You are right, I did hold SVXY short term, not long term.
I have one more question. I am thinking, what exactly does 'accumulative adjustment to tax basis' mean on K-1? Does it mean one's 'taxable income' (tax basis?) is increased/decreased by the number in that cell on K-1? It seems that the 'adjusting tax basis on 1099B' thing is just offsetting such 'accumulative adjustment to tax basis', in other words, bringing down the tax basis by the amount it is increased by K-1? Is this correct? If yes, then my question is why do we bring it down manually?
You have mentioned before that the 'income' on K-1 and the transaction gain/loss from trading e.g. SVXY are two different concepts. The former being the income passed along to investors from the partnership, and the latter being simply the difference between trade proceeds and costs.
Now if that is the case, why should we adjust the cost basis of the trading transactions by the amount of the 'income' passed long by the partnership on K-1? I am confused: isn't the 'income' on K-1 independent from the trading transactions? Many have mentioned that they have gained from the tradings, but K-1 shows a loss, or vice versa. Doesn't it mean that no matter you gain or lose from trading the ETF, your 'income' from the partnership is just on top of that, and you may be paying tax on 'income' of the partnership even if you have lost money trading, or vice versa? But why does everyone say 'do no count the same gain/loss twice'? Am I missing something?
Probably silly questions. Many thanks
There are no silly questions when it comes to these K-1s.
Again, I am not a tax expert, so take my attempts at answers with a grain of salt.
The "cumulative adjustment to tax basis" column is showing you which transactions in your history caused an adjustment to your tax basis (or cost basis) and the amount of that adjustment. Note that if you total up this column, it should equal the total implied by the K-1 boxes (for most K-1s this would mean adding up boxes 1 through 11 and subtracting 12 through 13). For the K-1s I've seen, it should also equals the box L current year increase (decrease) entry. Basically, it is showing you how the partnership distributed its activities to you throughout the year. Note that I've never seen a daytrade cause a non-zero "cumulative adjustment to tax basis." It always seems to be something I've held long overnight that triggers the partnership to pass on its income or deductions to me.
This "cumulative adjustment to tax basis" is indeed showing you when and how your cost basis in the partnership is affected during the year. Note that if the partnership distributes $1,000 to you via Box 11 C, then your cost basis will increase by the same amount. You will report the $1,000 as Sec. 1256 contract income (Form 6781, Line 1) but your cost basis will increase by $1,000 as well. So when you exit the K-1 position, you won't have to pay taxes on the first $1,000 in profit (if you have a profit). I think the "cumulative adjustment to tax basis" column can be used to accurately keep track of your cost basis intra-year. Note that if you don't liquidate the K-1 position entirely by year end, then you could be paying taxes on the distributed K-1 income, but not get any tax benefit for the increase in cost basis (yet). Only when you exit the position does the cost basis come into play. So you could pay more in taxes this year (on the distributed income) and then less the next year (because of the increased cost basis). Overall, it should approximately balance out.
As to why you adjust your cost basis, I think the basic reasoning is that if you are getting income from the partnership, then it implies the shares that you own are worth less after the payment. It is like when a stock pays a dividend, the share price adjusts to reflect this dividend payment. If K-1 partnerships did not work this way, then no one would own them because you would be essentially double-taxed. And if you do not adjust your cost basis because of partnership income, then you would be incorrectly double-taxing yourself (which is probably why people say, "do no count the same gain/loss twice").
Yes, the income on the K-1 is mostly independent from the trading profits. The only thing that ties them together is that the income reported to you on the K-1 is calculated based on what days you held the stock long. Whether you made a profit or loss on the transactions has nothing to do with what is reported on the K-1 as your share of the partnership activities. However, if you report the K-1 income without adjusting your cost basis, then you are doing it incorrectly and harming yourself financially (assuming the K-1 income is positive).
Again, I like to view these K-1s as just moving money from one spot to another. If you gain income from the K-1 partnership activities, then you must lose that same amount of income from your position in the stock (and vice versa). The end result will approximately be the same tax liability but you must dot the i's and cross the t's to report it in such a way that it will satisfy the IRS.
