What is the S1008 purpose code?

Purpose code S1008 is used when an Indian business sends money abroad to pay for research and development services. This covers work like contract research, laboratory testing, product development studies, clinical or field trials, or other R&D activities performed by an overseas organisation for your business. It does not cover the import of physical research equipment or materials, which falls under the relevant import of goods purpose codes instead. Under RBI FEMA guidelines, this outward payment is classified under other business services and reported accordingly.

When to use S1008 purpose code?

Use S1008 when you are paying an overseas vendor for research and development services delivered to your business in India, such as contract research, product prototyping or clinical studies. It is the correct RBI purpose code for buying R&D services from a foreign partner, whatever your business structure. S1008 covers the research service, not the sale of any underlying equipment or goods.

When to use a different code:

  • Use the purpose code for technical testing, inspection or certification services when the payment is for those activities rather than broader research
  • Use the purpose code for consulting or professional services when the payment is for general business or management consulting rather than R&D
  • Use the matching P code when you are receiving money rather than paying

Who typically uses S1008 purpose code?

Indian companies, startups and research-focused organisations that outsource research and development work to overseas labs, universities or specialist R&D firms. It applies whether you pay as a private limited company, LLP, partnership or proprietorship, as long as the R&D service is provided from outside India.

Examples of transactions covered

  • Payment to a foreign contract research organisation for conducting clinical trials on a new formulation
  • Fees to an overseas university lab for product performance testing and analysis under a sponsored research agreement
  • Milestone payment to an international R&D partner for developing and validating a new prototype
  • Annual charges to a foreign research firm for ongoing market and technology research services

When NOT to use S1008 purpose code

  • The payment is for technical testing, inspection or certification services rather than broader research and development
  • The payment is for general business, legal or management consulting services instead of R&D work
  • The payment is for importing research equipment, instruments or materials as goods rather than services
  • You are receiving money rather than paying (use the matching P code)

Documents required

To send a payment under S1008, keep the following documents ready so your authorised dealer bank can verify the transaction and report it correctly under FEMA.

DocumentPurpose
Form A2 with PANStandard RBI form where you declare the remittance details, purpose code and your PAN.
Form 145Income tax declaration for outward remittances, used to determine taxability under Rule 220 and Section 462.
Vendor invoiceDetailed invoice from the overseas R&D service provider describing the research or development services rendered.
Contract or statement of workResearch agreement, scope of work or engagement letter that sets out the R&D activities, milestones and commercial terms.

How is a S1008 Purpose Code declared?

Declaring the code is pretty straightforward. Here's how the payment gets tagged and reported.

  1. Receive the vendor invoice: Your overseas R&D partner bills you, clearly describing the research and development services delivered.
  2. Determine taxability: Establish whether the payment is chargeable to tax in India, since that decides which part of Form 145 you file.
  3. File Form 145: Submit the declaration before remitting, with Form 146 from your CA where the taxable amount exceeds ₹5 lakh in the Tax Year.
  4. Complete Form A2: State the purpose of the outward remittance as S1008 and submit the supporting documents to your bank.
  5. Get your MT103: Once the payment is sent, request the SWIFT MT103 as proof and retain your Form A2 record.
  6. With a traditional bank you handle each step of the payment journey. But with a platform built for cross-border payments, you can preselect a default purpose code so the payments go out smooth.

Common mistakes to avoid

A few common slips can hold up your payment or cause compliance issues. Here's what to watch for.

  1. Confusing R&D with general services: Tagging management consulting, routine testing or simple data collection as research and development when a different service code is more accurate.
  2. Code and invoice mismatch: The code not matching what your vendor invoice describes, which flags the payment.
  3. Assuming a Rule 220(3) exemption: Skipping Form 145 on a payment that is not on the specified list, which carries a ₹1,00,000 penalty per instance.
  4. Incomplete documents: Missing invoice, contract or Form A2, so the bank holds the remittance until provided.
  5. Missing PAN or KYC: Incomplete verification stops the bank from releasing the payment.
  6. Using an outward code for an inward receipt: Applying a payment code to money coming in instead of the matching P code.
