Vendor 1099 Compliance

Managing 1099 compliance for vendors can be complex. Muin simplifies it by automatically tracking payments, managing W-9 collection, and alerting you when vendors cross reporting thresholds.

Vendor 1099 Eligibility

Setting Up Vendors for 1099 Tracking

When creating or editing a vendor:

Navigate to Vendors → Directory
Select the vendor or click Add Vendor
In the Tax Information section:
- Toggle 1099 Eligible to Yes/No
- Select Form Type (1099-NEC for services, 1099-MISC for rent/royalties)
- Enter Tax Classification (Individual, LLC, Partnership, etc.)

Automatic Eligibility Detection

Muin helps identify 1099-eligible vendors:

Vendor Type	Default 1099 Eligible?
Individual/Sole Proprietor	Yes
LLC (Single-Member)	Yes
LLC (Partnership)	Yes
Partnership	Yes
S-Corporation	No
C-Corporation	No
Government Agency	No
Tax-Exempt Org	No

Note: Some C-Corps (attorneys) still require 1099s. Override as needed.

W-9 Management

Collecting W-9 Forms

Best practice: Collect W-9 before making the first payment.

From 1099 & W-9:

Go to Finance > Tax & Compliance > 1099 & W-9
Click Request W-9 on a vendor without one
The vendor gets an email with their vendor portal link
They upload the W-9 in the portal
Muin reads the TIN, entity type and address from it

Readiness and the TIN check

The top of the 1099 & W-9 page shows how many vendors are ready to file, for example “12 of 15 ready to file; 2 missing a W-9; 1 TIN not checked”.

The TIN check column shows Format checked, Not checked or Missing. We check the TIN’s format. We do not match it with the IRS. A vendor with a W-9 and a TIN in the right format reads Ready to File.

Manual Upload:

Go to vendor’s profile
Click Upload W-9
Upload scanned document
Review extracted information
Confirm details

Payment Threshold Tracking

Automatic Tracking

Muin totals what you paid each vendor from vendor bills recorded as paid:

Bills marked paid with Record Payment on Smart Payments > Vendor Bills
Bills recorded in a Payment Run

What counts:

The amount you actually paid, net of any early-pay discount.
Less any refund the vendor made on those payments in the same tax year. The threshold check uses the net figure.
Bills paid in the tax year you are viewing. A bill paid in an earlier year is left out.
Bills paid by credit card or Venmo are left out. The card processor or Venmo reports them on Form 1099-K. Zelle, ACH, check, wire and cash payments are counted.
Only payments in US dollars count. A payment in another currency is left out and listed on the 1099 dashboard for review, with its amount in that currency. Such payments are often reported on Form 1042-S instead.

Threshold Monitoring

The 1099-NEC threshold depends on the tax year:

Tax year	Threshold
2025 and earlier	$600
2026 and later	$2,000 (the platform default)

Dashboard Alerts:

Alert Level	Share of the tax-year threshold	Action
Approaching	80%	Ensure W-9 on file
Warning	90%	Verify all info complete
Crossed	100%	Vendor requires 1099

Click Payment History tab

Follow up on outstanding W-9 requests

Common Issues and Solutions

Vendor Won’t Provide W-9

Options:

Explain legal requirement
Offer secure digital submission
If refused, may need to withhold 24% (backup withholding)

Can’t Verify Tax ID

Muin checks the TIN’s format only. It does not match the TIN with IRS records.

Causes:

Name doesn’t match IRS records
Typo in Tax ID
Wrong tax classification

Solutions:

Request corrected W-9
Have vendor verify name matches IRS registration
Check for common typos (0 vs O, 1 vs l)

Vendor Classification Unclear

Question: Is this vendor a Corporation?

How to check:

Review W-9 Line 3 (Federal tax classification)
Check state business registry
Look for “Inc.” or “Corp.” in business name
When in doubt, request clarification from vendor

Best Practices

Year-Round Compliance

Collect W-9 at onboarding - Don’t wait until year-end
Verify tax IDs promptly - Allows time for corrections
Monitor thresholds monthly - No surprises in January
Keep records updated - Address changes matter for mailing

Vendor Communication

Be proactive - Send friendly reminders
Explain why - Help vendors understand requirements
Make it easy - Use digital W-9 collection
Document refusals - Protect yourself legally

When it goes wrong

A vendor you paid is missing from the 1099 list. The bill is not recorded as paid, it was paid by credit card, or it was paid in another tax year. Record the payment on the bill or in a Payment Run.

A vendor’s total is lower than the bills. The total is what you paid, net of early-pay discounts and of refunds made in the same tax year. Payments in a currency other than US dollars are not counted; the dashboard lists them separately.

Next step

Open Finance > Tax & Compliance > 1099 & W-9 to review each vendor’s total. See 1099 Tax Tracking.
