When you acquire a business, you might be struggling to understand who is supposed to file a 1099, especially when payments were made before and after the acquisition. If the acquisition qualifies under IRS successor/predecessor rules, you are the successor. The predecessor is generally the business that made the reportable payments before the acquisition and was responsible for reporting them. You may need to determine whether you or the predecessor is responsible for each payment.
In some cases, you can combine the predecessor’s reportable payments with your own, but the IRS has specific conditions for doing so. Let’s deep dive.
When you acquire a business, you first need to check if the payer and Employer Identification Number (EIN) have changed. If the acquired business continues as the same legal entity with the same EIN, as in many stock purchases, there’s no predecessor/successor split. That entity stays the payer for the full year.
But when the acquisition creates a separate predecessor and successor:
You may also use the IRS combined reporting procedure when the required conditions are met. In that case, you take on the predecessor’s reporting responsibilities for the forms included in the agreement.
The successor can use combined reporting after an acquisition when the IRS requirements are met and the successor and the predecessor both agree on the forms covered.
So essentially, you can use combined reporting when all of the following apply:
With combined reporting, the successor can include the predecessor’s reportable payments with its own for the year of the acquisition. Any federal income tax withheld on those payments is included as well.
You report all the combined amounts on one return per recipient for each recipient covered by the agreement. For example, if the predecessor paid a contractor $1,200 before the acquisition and you paid the contractor $1,500 after the acquisition, the contractor would receive one Form 1099-NEC from you showing $2,700.
You do not have to include every information return in the arrangement. You and the predecessor can limit combined reporting to:
For example, you could combine Form 1099-DIV reporting while filing other Forms 1099 separately.
Combined reporting changes who files the return, but it does not change the 1099 rules that apply to each payment. You still need to check the payment type, the correct form, and the applicable reporting threshold.
For 2026 payments, the OBBBA raised the federal reporting threshold for certain Form 1099 payments from $600 to $2,000.
That change does not apply across the board. Royalties, gross proceeds paid to attorneys, and several other payment types still have their own reporting thresholds and rules.
So, when you use combined reporting, apply the rule for each payment type before adding the amounts to your return.
After an acquisition, the payment type still determines which information return applies. Use the applicable rule for each payment rather than applying the $2,000 threshold to every Form 1099 category.
A business acquisition does not automatically require Form 1099-CAP, Changes in Corporate Control and Capital Structure. It generally applies when control of a corporation is acquired or the corporation undergoes a substantial change in its capital structure, and shareholders receive cash, stock, or other property as part of the transaction.
For an acquisition of control, the IRS rules generally look for at least 50% control and stock involved in the transaction worth $100 million or more, along with the other applicable requirements. Form 1099-CAP is generally filed by the corporation required to file Form 8806 and furnished to affected shareholders who are not exempt recipients.
These rules are separate from the successor/predecessor rules, which determine how information-return reporting is handled between the businesses after an acquisition.
Once you know which returns you file and which the predecessor files, check the deadline for each form. The dates can be different, depending on the type of Form 1099 and whether you are filing on paper or electronically.
For 2026 information returns, the Information Returns Intake System (IRIS) will be the only IRS intake system available during the 2027 filing season. The Filing Information Returns Electronically (FIRE) system is being retired.
If you plan to eFile, you need to apply for your IRIS Transmitter Control Code (TCC) as early as possible. The IRS says a typical application is processed within 45 business days, although processing times can vary.
Through the IRIS Taxpayer Portal, you can enter all your data manually, or upload a CSV file. You can also create and file returns, download recipient copies, keep filing records, and make certain corrections.
How the 1099 reporting is handled depends on whether you and the predecessor report separately or use combined reporting. Here are a few examples:
The predecessor generally reports payments and withholding from before the acquisition, while you report those from after the acquisition.
Yes. A successor may combine the predecessor’s reportable amounts with its own when the IRS requirements are met and both parties agree to use the procedure.
No, it is not. The transaction has to qualify, and the successor and the predecessor must agree to use the procedure.
The successor files the combined return and reports the applicable amounts from both periods.
No. If the same legal entity and EIN continue after the acquisition, the payer may remain the same and there may be no predecessor/successor split.
For many qualifying nonemployee payments, the federal threshold is $2,000, but only for payments made after December 31, 2025.
After a business acquisition, you are left working with multiple EINs, vendor records, W-9 information, and payment histories. But by keeping these records organized, you can make it easier to determine which payments the predecessor reports, which ones you report, and whether combined reporting applies.
Tax1099 gives you the option to manage your post-acquisition 1099 filing in one place. You can also collect and organize vendor information, review payment details, prepare the applicable Forms 1099, deliver recipient copies, and eFile your returns.
