To send money to Ireland for an independent contractor, a US business needs the contractor's IBAN, their bank's BIC or SWIFT code, a W-8BEN on file for tax records, and a consistent payment date each month.
Paying an ongoing Ireland-based contractor is different from paying a one-time supplier. It is a recurring payment to one person, not a purchase order. A late retainer is not a late shipment. It is a late paycheck.
Key Insight: Ireland is home to the European operations of many well-known technology companies, and Dublin's tech district is sometimes called "Silicon Docks" because of it. That is why your next great developer is more likely to be in Dublin than three blocks from your office. Once that relationship starts, the payment process needs to be built for a monthly rhythm, not a one-off transaction.
Why a US Tech Consultancy Ends Up Hiring in Ireland
Ireland shares a language with most US clients, sits in the European Union and the eurozone, and has built a deep bench of software talent around the local offices of major global technology companies. For a small or mid-size Austin consultancy trying to staff a client project quickly, an experienced contract developer in Dublin, Cork, or Galway can be easier to find than staffing the same skill set locally on short notice.
Once your team brings that contractor on board for an ongoing engagement, the accounting side of the relationship becomes its own small, repeatable process: agreeing a retainer, collecting the right paperwork, and paying it correctly on the same date every month.
One detail worth checking up front: many experienced Irish contract developers operate through a personal service or umbrella company rather than invoicing as an individual. If that is the case for your contractor, the paperwork and payment routing change slightly. The company, not the individual, typically completes a W-8BEN-E instead of a W-8BEN, and your payment goes to the company's IBAN rather than a personal account. Ask which setup your contractor uses before the first payment so you collect the right form the first time.
What an International Payment Typically Costs a US Business
The World Bank's Remittance Prices Worldwide database tracks global transfer costs. In its Q3 2025 report, banks averaged 14.99 percent and digital providers averaged 4.59 percent, against a global average of 6.36 percent. That data covers consumer transfers, not recurring B2B contractor payments, so it will not match your exact retainer cost. But the same underlying mechanic applies either way: a bank layering an FX spread and fees on top of the transfer tends to cost more than a direct digital-payment channel.

On a monthly retainer, a wide markup repeats every single cycle, so it compounds into a real cost over a year of payments. Ask any provider what it charges on the full retainer amount, every month, not just the headline rate. Zil Remit's own rates for a given transfer are separate from the general market figures above, and sending directly through a payment platform built for cross-border transfers avoids the extra correspondent-bank layers that drive up the bank-channel averages cited here. For more on why a low headline rate does not always mean a low total cost, see why the cheapest-looking transfer isn't always the cheapest one.
A Contractor Retainer Is Not the Same Payment as a Supplier Invoice
| What Changes | One-Time Supplier Invoice | Monthly Contractor Retainer |
|---|---|---|
| Payment trigger | A purchase order and matching invoice | The calendar, on an agreed date each month |
| Amount | Varies by shipment or order size | Usually fixed, unless hours or scope change |
| Tax documentation | Business registration details as needed | A W-8BEN on file for the individual |
| Reference used | Invoice or PO number | Retainer period, such as the covered month |
| Impact of a delay | Can hold up a shipment or restocking | Delays a person's personal income |
What You Need Before You Pay an Irish Contractor
Irish bank accounts, personal or business, run on the SEPA (Single Euro Payments Area) network. Your US payment starts outside SEPA, so it needs the contractor's IBAN plus the receiving bank's BIC or SWIFT code. Collect both once and the retainer becomes a quick lookup every month instead of a fresh round of questions.
Contractor IBAN
Confirm this directly with the contractor rather than reusing a number from a chat message or an old email, since a single wrong digit can send a payment to the wrong account.
Bank BIC or SWIFT code
This identifies the receiving bank itself. A payment to Ireland typically needs both the IBAN and the BIC to route correctly.
W-8BEN on file
Most US businesses ask a foreign independent contractor to complete this form to document their foreign status for tax records. Confirm the specifics for your situation with a tax advisor before the first payment.
A retainer agreement with a set payment date
Put the amount, currency, and payment date in writing so neither side has to ask each month whether the payment went out.
Deciding Which Currency Carries the Exchange Rate Risk
A monthly retainer forces a decision that a one-time invoice does not: which side absorbs currency movement. The size of that swing is easy to underestimate: a 5 percent move in the EUR/USD rate on a 4,000-euro monthly retainer works out to roughly 200 dollars a month, moving one way for your budget and the opposite way for your contractor's paycheck. Neither approach is wrong, but write down which one you are using, and say so plainly in the retainer agreement, so a rate swing does not turn into an awkward conversation three months in.
| What Happens | You Fix the EUR Amount | You Fix the USD Amount |
|---|---|---|
| Contractor's euro income | Stays the same every month | Rises or falls with the exchange rate |
| Your dollar cost | Shifts a little with the exchange rate | Stays the same every month |
| Best for | Giving the contractor a predictable income | Keeping your own budget predictable |
Whichever side you choose, confirm with your payment provider that the exchange rate you review before sending is the same rate applied to the transfer, not an estimate that can shift after you submit it.
Keeping Contractor Payment Records Organized
A recurring payment is easy to let slide into informal habits, which is exactly when a mistake slips in. Keep a simple record for each Ireland-based contractor: their IBAN, BIC, agreed amount and currency, W-8BEN, and a log of payment dates. Review it once a quarter to make sure nothing has gone stale, such as a contractor switching banks without telling you.
Common Mistakes With Recurring Contractor Payments to Ireland
The most common issue is a payment date that quietly drifts from month to month, which makes it harder for a contractor to plan around their own bills. The second is treating the retainer like a one-time invoice and re-collecting bank details every cycle instead of keeping them on file. Fixing the date and keeping one clean record solves most of the friction before it starts.
Step-by-Step: Setting Up a Monthly Payment to an Ireland-Based Contractor
-
1
Collect the contractor's IBAN and BIC directly from them
Confirm the details in writing before the first payment.
-
2
Get a completed W-8BEN on file
Check with a tax advisor if you are unsure which form applies to your situation.
-
3
Agree on the currency, amount, and a fixed payment date
Put it in the retainer agreement so both sides know what to expect.
-
4
Enter the payment details and review before sending
Check the IBAN, BIC, amount, and the month being covered.
-
5
Send the payment on the agreed date and save the confirmation
File it with that month's retainer record.
-
6
Let the contractor know it is on the way
A short message like "this month's retainer just went out, same amount as usual" takes almost no effort and builds trust over dozens of payment cycles.
Frequently Asked Questions
What is the difference between paying a contractor and paying a supplier in Ireland?
A supplier payment is usually tied to a purchase order for goods and can vary invoice to invoice. A contractor payment is typically a fixed monthly retainer paid to one person on the same date each cycle, so the process is more about consistency than matching a shipment.
Does a US company need a W-8BEN for an Irish contractor?
Most US businesses ask a foreign independent contractor to complete a W-8BEN to document their foreign status for tax records. Rules can vary by situation, so confirm the specifics with a tax advisor before the first payment.
How do exchange rate changes affect a fixed EUR retainer?
If you agree on a retainer in euros, the dollar cost to your business shifts with the exchange rate even though the contractor's euro amount stays the same. If you agree on a dollar amount instead, the contractor's euro income is what moves instead.
What bank details do I need to pay an individual in Ireland?
You need the contractor's IBAN, the same identifier used for a business payment, since Ireland's bank accounts run on the SEPA network for both individuals and companies. Because the payment originates from a US account outside that network, you also need the receiving bank's BIC or SWIFT code to route it correctly.
How should accounts payable track recurring contractor payments to Ireland?
Keep a simple log with the contractor's IBAN, BIC, agreed retainer amount and currency, payment date, and W-8BEN on file, so each month's payment is a quick lookup instead of a fresh round of questions.
What if a payment detail is wrong or the money does not arrive as expected?
Review the confirmation record against the invoice or retainer period as soon as you send it, and keep your payment provider's support contact on hand so you can flag a mismatch quickly if the contractor reports one.
Conclusion
Hiring a contract developer in Ireland is common for growing US tech consultancies, and paying that person well comes down to a few repeatable habits: verified bank details, the right paperwork on file, a clear agreement on currency, and a payment date that never moves. For comparison, see how another US company handles a different kind of recurring payment to an Irish partner. Once your Austin team builds its own routine, the monthly retainer becomes background work instead of a recurring scramble.
