Filing 1041 - Do you need to submit 1099-B to IRS when e-filing

Hi,

I'm filing a 1041 for a trust and would like to e-file the return. The income for the trust is investments and when I go to the income section TurboTax Business asks if I want to provide summarized information from my 1099-B. I said yes and entered the summarized information. The instructions say that I will need to attach the 1099-B statement later and they would walk me through that. However there is no place to attach the 1099-B statement. I searched on these forums and talked with a TurboTax representative and confirmed there is no way to attach the 1099-B statement. The representative mentioned something about a different version having that ability.

Is it a requirement to provide the 1099-B statement to the IRS when filing? If it is then I would conclude I am unable to e-file with TurboTax. The only other option I see is typing all the individual investments in....which I'm not a huge fan of.

Any feedback/suggestions is welcomed.

Thanks!

Josh

I type in the sales of the non-covered investments, and I also type in the sales of the covered investments that have adjustments (wash sales or market discount). The rest of the covered sales I enter as totals on Schedule D Lines 1a and 8a. I've never attached the 1099-B to my returns.

You cannot add a scanned attachment in TurboTax Business with the exception of your 8453-FE. However, if you have PDF software that is capable of combining documents, you can combine your 1099-B with your 8453-FE (although there is no guarantee that the IRS will process both documents).

Yes it is required to provide the 1099-B statement with your tax return if you only enter the summary.

Yes you are correct, you will not be able to e-file your 1041 unless you want to type in the individual transactions from the 1099-B.

@JillS56

Thank you for the reply and confirming I need to provide the 1099-B or type all the entries in. That's an interesting thought about combining the 1099-B with the 8453-FE, but I probably won't want to risk the IRS not processing both documents correctly.

I will probably just print out and mail in the return vs. typing everything in.

Thanks again for the feedback!

I need to attach my 1099B as well. For the cost of the TTax program it is crazy that it won’t attach a 1099B.

Thanks for your help.

I have been using a method similar to that described by @mtp79 above to avoid having to send in any paperwork by mail. TurboTax implies that you can enter group totals for all 1099-B transactions, but if you do this, you might have to send in paperwork by mail. The types of transactions that I have come across that should NOT be grouped are any where the cost basis was not reported to the IRS, wash sales, US Treasuries, and brokered CDs with accrued market discounts. The process of grouping transactions was more user-friendly years ago in TurboTax than it is today. There are other ways to do it, but this year I found it easier to skip importing, manually subtract out the transactions that should not be grouped from the group totals given on the 1099-B, and then enter the revised group totals for everything that could be grouped, and then create separate sections listing individual transactions for all the transactions that should not be grouped when e-filing. I have to file state taxes in Michigan which has limits on how many individual transactions can be listed when e-filing, so leaving everything ungrouped isn't an option for me.

The IRS form 8453 (for 2025) does not list 1099-B as an applicable attachment for the checkboxes provided.
