A Step-by-Step Guide to 1099s in Business Central
Managing vendor 1099s in Business Central has become more streamlined with the latest updates. This guide will walk you through setting up, preparing, and finalizing 1099 forms to ensure compliance and efficiency in your year-end reporting.
Step 1: Setting Up and Maintaining 1099s
Activating the 1099 Feature
Before getting started, make sure 1099 reporting is enabled in Feature Management.

Locate the option Enable using 1099 forms to transmit tax data to the IRS, set it to All Users, and confirm activation. Users will need to log out and back in for changes to take effect.

Upon activation, the IRS Forms Guide Wizard will launch. Here, specify the reporting year (e.g., for 2024 filings, enter 2024) and choose Create New Setup to generate the necessary forms and form box data.

Manual Setup Adjustments
You can modify settings such as:
- Collect Details for Lines – Stores additional transaction data for better tracking.
- Protect TIN – Masks sensitive Taxpayer Identification Numbers when printing forms.
- Email Subject & Body – Customizes email messages when sending 1099s electronically.
Defining Reporting Periods
Navigate to IRS Reporting Periods to specify the reporting year and start/end dates. Copy the setup from the prior year to maintain consistency in your reporting structure.

Each type of 1099 (MISC, NEC, DIV, INT, etc.) is assigned corresponding Form Boxes, which define the minimum reportable amounts for each category.

Step 2: Vendor Setup & Preparation
Assigning 1099 Status to Vendors
To ensure accurate reporting, vendors requiring 1099s must be set up properly:
- Run Vendor Setup from the IRS Reporting Periods page.
- Enter Vendor No., Form No., and Form Box No.
- Populate the Federal ID Number on the vendor card.
- If vendors opt to receive 1099s via email, enable Receiving 1099 and enter their email address.

Propagating 1099 Data
If 1099 codes weren’t assigned before processing vendor payments, Business Central offers a Propagate Feature to update transactions retroactively. However, use this with caution, as it applies the 1099 code to the entire invoice amount, even if only a portion was taxable
- To mitigate risk, export vendor ledger entries before propagating.


Validating 1099 Information
To verify 1099 amounts before submission:
- Review the IRS 1099 Form Documents page.
- Drill down into vendor transactions to confirm reported amounts.
- Export vendor ledger entries for cross-checking.
Step 3: Finalizing & Submitting 1099s
Generating 1099 Forms
Navigate to IRS 1099 Form Documents and select Create Forms. You can:
- Process all vendors or filter for specific ones.
- Select a particular 1099 form type (e.g., NEC, MISC) or generate all.
- Replace previously created forms if necessary.
Each form must be released individually before submission.


Submitting to the IRS
Business Central supports electronic submission via IRIS APIs (available in an upcoming minor release). Once submitted, the status will update to Submitted.

Printing and Emailing 1099s
While Business Central does not support printing directly on pre-printed IRS forms, you can:
- Print Copy B, Copy C, and Copy 2 for vendor distribution.
- Email 1099s by ensuring vendor email settings are configured correctly.
- Automate bulk email distribution for multiple vendors at once.

Before emailing, verify that email accounts are properly set up under Email Accounts.
Final Thoughts
By leveraging Business Central’s 1099 features, businesses can simplify their tax reporting process while maintaining compliance. Regularly reviewing vendor data, utilizing the propagate tool cautiously, and validating reports before submission will help ensure smooth year-end processing.
