Who Pays the Fees When You Pay an International Contractor? Wire Charges, FX Spread & W-8BEN, Settled

You agreed to pay an overseas contractor $2,000. The wire goes out, and a week later they message you: "I only received $1,943 — where's the rest?" Now you are reverse-engineering a bank statement, an intermediary deduction, and an exchange rate you never saw, trying to figure out who owes what.

This is one of the most-asked, least-clearly-answered questions in cross-border work. The big payment brands have an incentive to keep it fuzzy, because the fuzz is where their margin lives. So here is the copy-pasteable answer: who pays the wire fee, who eats the FX spread, which tax form you need before the first payment, and a sample contract clause you can drop in today. Every hard number below is sourced. Tax points are general information, not advice — confirm specifics with your accountant.

The short answer: who pays what

In a clean, well-structured contractor payment, the sender (you) pays the transfer costs and the contractor receives the agreed amount in full. That is the default you should aim for, and it is a choice you actively make on the wire, not something that happens automatically.

Here is the quick map of who pays each cost in a typical setup:

The two costs people forget are the intermediary fee (which the OUR charge code is designed to absorb) and the FX spread (which is invisible unless you go looking). The rest of this article makes each one concrete.

Wire transfer fees: OUR, SHA and BEN explained

When you send an international bank wire, the SWIFT instruction (the MT103 message) carries a "details of charges" field that tells every bank in the chain who is responsible for fees. It takes one of three values: OUR, SHA, or BEN (Levro: SWIFT Transfer Fees Explained). In the newer ISO 20022 format these appear as DEBT, SHAR, and CRED, but the meaning is identical (Karbon: OUR, BEN & SHA charges).

OUR (sender pays everything). You cover your bank's fee plus any charges intermediary banks add along the way, so the full amount lands with your contractor (Deel: OUR, BEN and SHA explained). This is the cleanest option for a working relationship — no surprises, no "where's the rest" message.

SHA (shared). You pay your sending bank's fee, but any charges added by intermediary banks get deducted from the transfer before it arrives, so the contractor receives a short payment they did not agree to (Levro: SWIFT Transfer Fees Explained). SHA is the most common bank default — which is exactly why short-payment surprises are so common.

BEN (beneficiary pays). All fees come out of the amount sent, so the contractor absorbs every charge and there is no guarantee they receive the exact figure you intended (Deel: OUR, BEN and SHA explained). Avoid BEN for contractor pay unless you have agreed in writing that quoted amounts are gross-of-fees.

The actual numbers. Outgoing international wire fees from US banks "often cost upwards of $50" (Bankrate: How Much Are Wire Transfer Fees). Specific examples from the same data: U.S. Bank charges $50, Truist $65, and Huntington $75, while Bank of America and Chase top out around $45-$50 for an outgoing international wire (Bankrate). On top of the sending bank's fee, intermediary (correspondent) banks in the chain can each deduct an additional charge in transit — typically a small flat fee, though the exact amount is rarely disclosed up front. Choose OUR and you absorb those intermediary fees; choose SHA and your contractor does.

The hidden cost: the FX spread (and who eats it)

The wire fee is the cost you can see. The FX spread is the cost you cannot — and it is usually the bigger one.

When your bank converts currency, it does not give you the real "mid-market" rate (the one you see on Google or XE). It gives you a worse rate and pockets the difference. That difference is the markup, and it is pure margin for the bank (Airwallex: Bank exchange rate markup).

How big is it? Traditional banks typically add roughly 2% to 5% above the mid-market rate, and the spread is larger for less-traded (mid-tier) currencies than for majors like EUR or GBP (Bancoli: FX Markup). Put differently, this markup "ranges from 2% at major banks to 5% at regional institutions" (Bancoli: FX Markup).

Why this matters more than the flat fee: on a $2,000 payment, a $45 wire fee is 2.25%. A 3% FX markup on the same $2,000 is $60 — and unlike the wire fee, nobody hands you a receipt for it. It is baked into the exchange rate. On recurring monthly contractor payments, that invisible 3% compounds into real money fast.

Who eats it? Whoever's account does the currency conversion. If you send USD and your contractor's bank converts to local currency, the contractor eats the markup at their bank's rate — often a worse rate than yours. If you convert before sending, you eat it. The fix is to make this a conscious decision in the contract, not an accident of which bank happens to convert. We will cover the clause below.

Tax forms before you pay (W-8BEN and friends)

This section is general information, not tax advice. Cross-border tax depends on your jurisdiction and your contractor's — confirm the specifics with a qualified accountant before relying on any of it.

For US payers, the headline rule is blunt: collect a valid W-8BEN (for individuals) or W-8BEN-E (for entities) from a foreign contractor before you pay them. Without that documentation, the default rule can treat a US-source payment to a foreign person as subject to 30% withholding (IRS: NRA withholding).

A few practical points that come up constantly:

• The form goes in before the first payment. The W-8BEN "should be provided to the withholding agent or payer before income is paid or credited to you" (IRS: Instructions for Form W-8BEN). Get it on file during onboarding, not after a payment is already disputed.
• Services performed entirely outside the US are generally foreign-source. When a non-US contractor performs all work outside the United States, the payment is normally not subject to that chapter 3 withholding, and you generally do not issue a 1099-NEC (Tipalti: 1099 for Foreign Contractors). The W-8BEN is still the document that supports treating it that way.
• W-8BEN is for individuals; W-8BEN-E is for companies. If your contractor invoices through a foreign entity, you collect the W-8BEN-E version instead (Tipalti: 1099 for Foreign Contractors).
• It has a shelf life. A W-8BEN is generally valid for 3 years from signing, then needs renewal, and becomes invalid immediately if the contractor's circumstances change (IRS: Instructions for Form W-8BEN).
• Keep records even when nothing is withheld. Hold the form on file and keep records of who was paid, why, and the amount (Tipalti: 1099 for Foreign Contractors).

The simple operating rule: no W-8 on file, no payment goes out. Bake it into onboarding and you never have to claw back a withholding mistake. (Different mechanics apply when you engage people through an employer of record rather than as direct contractors — see EOR vs staff augmentation vs PEO for how the compliance burden shifts.)

Payment methods compared (bank wire, Wise, PayPal, platforms)

The method you choose determines both the visible fee and the invisible spread. Here is how the common options stack up for paying an international contractor.

The numbers behind that table: bank wires run $35-$50 (and up) outbound plus per-intermediary deductions in transit, with a 2%-5% FX markup baked in (Bankrate, Bancoli: FX Markup). Wise charges a transfer fee that "starts at from 0.57%" and uses the mid-market rate with no markup (Wise: PayPal Business vs Wise Business). PayPal adds cross-border and fixed fees plus a roughly 3-4% markup on currency conversion (around 4% on goods/services and personal transfers, 3% on other transactions) (Wise: PayPal Business vs Wise Business).

The honest takeaway: for recurring contractor payments, a mid-market-rate service like Wise almost always beats a bank wire once you count the FX spread — the saving is in the part of the cost you cannot see. Reserve bank wires for large one-offs where the receiving party specifically wants a SWIFT transfer. This matters when you are hiring developers in Pakistan from the US or anywhere with a mid-tier currency, where bank FX markups sit toward the higher end of that 2-5% range.

A sample fee-allocation clause for your contract

The single best thing you can do to avoid fee fights is to write the allocation into the agreement. Here is a plain-English clause you can adapt. It is a starting template, not legal advice — have your counsel review before use.

Payment and Fees. All amounts stated in this Agreement are net amounts payable to the Contractor. The Client shall pay the Contractor via [bank wire / Wise / PayPal]. For bank wire transfers, the Client shall send funds using the "OUR" charge instruction, meaning the Client bears all sending-bank and intermediary-bank transfer fees so that the Contractor receives the full net amount stated on each invoice. Any fees charged by the Contractor's own receiving bank are the Contractor's responsibility. Currency conversion, where required, shall be performed at or near the prevailing mid-market exchange rate, and any conversion margin shall be borne by [the Client / the Contractor]. The Contractor shall provide a valid IRS Form W-8BEN or W-8BEN-E (or the applicable local equivalent) before the first payment.

The four things that clause nails down, and why each one matters:

• Net amounts — removes the "is this gross or net of fees?" argument entirely.
• OUR charge instruction — guarantees the contractor is not short-paid by intermediary banks.
• Receiving-bank fees on the contractor — sets the one expectation you genuinely cannot control.
• FX margin assigned to a named party — turns the invisible cost into a negotiated, explicit one.

How to keep payouts cheap and predictable at scale

One contractor is a clause. Twenty contractors across six currencies is a system. As you scale, the goal shifts from "pay this person correctly" to "make every payout cheap, on time, and self-documenting." A few principles:

• Standardize the method. Pick one primary rail (a mid-market service for most, bank wire for exceptions) so you are not re-deciding fees every cycle. Consistency is what makes the FX cost predictable.
• Collect tax forms at onboarding, not at payment. Make a valid W-8 (or local equivalent) a gate before anyone enters the payment system. No form, no payout — automated, not manual.
• Batch payments to cut per-transfer fees. Monthly batches beat ad-hoc transfers; every individual wire is another flat fee and another chance for an intermediary to skim.
• Track the all-in cost, not the headline fee. A "$0 transfer" with a 4% FX markup is more expensive than a low-percentage transfer at the mid-market rate. Measure what actually leaves your account versus what lands in theirs.
• Reconcile against net, automatically. Match each payout to the invoiced net amount and flag shortfalls. This is exactly the kind of repetitive busywork that should be automated rather than chased by hand each month.

This is also where the build-vs-buy question shows up. If managing payouts, tax forms, and reconciliation across a growing roster is eating real hours, the comparison is no longer just fees — it is your team's time. We break that trade-off down in in-house vs staff augmentation cost, and the broader question of how you engage people (contractor, staff augmentation, or employer of record) in EOR vs staff augmentation vs PEO.

The pattern across all of it: the fees are knowable, the tax rules are documentable, and the reconciliation is automatable. The companies that get burned are the ones treating each payment as a one-off instead of building the system once.

If you are paying international contractors and the fee math, tax forms, and monthly reconciliation are quietly eating your time, that is precisely the busywork we automate.
