1099 contractors at an agency: what the books need to track
Nine contractors, three of them overseas, half paid through a payment platform, all coded to one line called Professional fees. It works fine until you need to know what delivery costs, or until January.
An agency contractor bench needs three things captured through the year: correct tax documentation collected before the first payment, payments split between delivery cost and overhead, and each payment coded to the client it relates to. US contractors generally require a Form W-9 and, if paid $600 or more in a year, a Form 1099-NEC. Non-US contractors performing work outside the US are generally documented on Form W-8BEN and are usually not reported on a 1099. Getting this wrong makes delivery cost unknowable and turns January into a scramble.
What tax forms do agency contractors need?
Every contractor problem an agency has in January is a document somebody did not collect in March.
| Contractor type | Form to collect | Year-end reporting |
|---|---|---|
| US person or entity | W-9 | 1099-NEC if paid $600+ in the calendar year |
| Non-US individual, working abroad | W-8BEN | Generally not 1099-reportable |
| Non-US entity, working abroad | W-8BEN-E | Generally not 1099-reportable |
| Paid via a third-party settlement network | Still collect W-9 | May be reported by the platform instead |
Two practical rules save most of the pain. Collect the form before the first payment goes out, because chasing documentation from someone you no longer work with is unpleasant and frequently unsuccessful. And re-confirm annually for anyone still active, since circumstances and entity status change.
Payments made through certain third-party payment platforms may be reported by the platform rather than by you, which changes your 1099 obligation for those amounts. Because this interacts with how you pay people, confirm the treatment for your specific setup with a qualified tax adviser rather than assuming.
Splitting contractor cost properly
This is the part that affects your numbers rather than your compliance, and it is where most agencies lose visibility.
A contractor bench is almost never homogeneous. Some people deliver client work, some support the business, and a few do both in the same month. Coding all of them to one line makes cost of delivery meaningless.
| Contractor doing | Codes to | Affects |
|---|---|---|
| Client project work | Cost of delivery | Gross margin and client margin |
| A specific client's retained work | Cost of delivery, tagged to that client | That client's margin |
| Internal marketing or content | Overhead | Net margin only |
| Bookkeeping, ops, recruitment | Overhead | Net margin only |
| New business support | Overhead | Net margin only |
Where someone splits their time across delivery and internal work, split the invoice. It takes a minute at coding and it is the difference between knowing your delivery cost and estimating it.
Contractor spend that is genuinely attributable to one client should carry that client tag, exactly like salaried delivery time. The chart of accounts structure that supports this is worth getting right first.
The multi-currency wrinkle
Agencies with overseas contractors are usually paying in a currency other than their reporting one, frequently through a platform that applies its own rate and fee.
Three things to get right. Record the expense at the rate on the date of the transaction rather than whatever the month-end rate happens to be. Book the platform fee as its own cost rather than burying it in the contractor's cost, or you will overstate what that person costs you. And keep realised FX on a separate line, so a swing in delivery cost can be attributed to the currency rather than to the work.
Without that separation, an agency paying a Manila-based team in one currency and billing US clients in another will see gross margin move several points and have no way to tell whether it was pricing, efficiency or the exchange rate.
Contractor versus employee
Worth stating plainly because agencies get this wrong in both directions, and the consequences are asymmetric.
Classification is determined by the substance of the working relationship — the degree of control over how, when and where the work is done, the financial arrangement, and whether the relationship is open-ended and central to the business. It is not determined by what the contract calls it or by the person's preference.
The risk is asymmetric: misclassifying an employee as a contractor exposes the business to back taxes, penalties and interest, while the reverse mostly costs you money you did not need to spend. Rules differ substantially between jurisdictions, and an agency with contractors in several countries is subject to several sets.
If someone works exclusively for you, on your schedule, using your systems, indefinitely, that is worth a conversation with an employment adviser rather than an assumption.
Common questions
Do agencies need to issue 1099s to contractors?−
Generally yes for US contractors paid $600 or more during the calendar year, using Form 1099-NEC for non-employee compensation. Collect a W-9 before the first payment so you have the information when you need it. Payments made through certain third-party payment networks may be reported by the platform instead, which changes your obligation for those amounts.
Do you send a 1099 to a foreign contractor?+
Generally not, where the contractor is a non-US person performing services outside the United States. Instead you collect Form W-8BEN for individuals or W-8BEN-E for entities to document their foreign status. Retain the form; it is the evidence for why no 1099 was issued.
How should contractor costs be categorised in agency books?+
Split by what the contractor is doing. Client project work is cost of delivery and should carry the client tag. Internal work — marketing, operations, recruitment, new business — is overhead. Coding the whole bench to a single professional fees line makes cost of delivery unknowable and gross margin uninterpretable.
When are 1099-NEC forms due?+
Form 1099-NEC is generally due to both the recipient and the IRS by 31 January following the tax year. Because the deadline is early and does not move, the practical answer is to maintain the underlying data through the year rather than assembling it in January.
What's the difference between a W-9 and a W-8BEN?+
A W-9 collects the taxpayer identification number of a US person or entity and supports 1099 reporting. A W-8BEN certifies that an individual is a non-US person, and W-8BEN-E does the same for a non-US entity. Which one applies depends on the contractor's status, not on where you are.
