US clients often request W‑9 from US persons and W‑8BEN or W‑8BEN‑E from non‑US contractors, influencing tax reporting like 1099 or 1042‑S. Provide accurate legal names, addresses, and treaty information where relevant. Clear documentation reduces withholding surprises and keeps onboarding timelines short and friendly.
For many B2B digital services into the EU, the reverse‑charge mechanism applies when the buyer has a valid VAT number, so no VAT is charged by you. Note local GST or digital services rules elsewhere. Capture evidence of client location and tax IDs to defend decisions later.
Store invoices, contracts, bank confirmations, and exchange‑rate evidence from reliable sources like central banks or your provider’s statements. Tag each payment with client, project, and currency. When audits or visa applications appear, comprehensive records speed responses, calm nerves, and validate every number in your financial story.
