the challenge

Every cross-border payment carries a tax obligation

Dividends paid to foreign investors. Salaries paid to international employees. Fees paid to overseas contractors and vendors. Each one is subject to residency rules, withholding rates and tax treaties that vary by country, by person and by year.

Many organizations still manage this with spreadsheets, manual reviews and outside advisers. The result is over-withholding, missed treaty relief, reporting errors and regulatory exposure.

Sprintax replaces that with one secure, automated and auditable platform, from the first payment to the final reclaim.

Sprintax Returns has completely transformed tax season for DePauw undergraduates. More students submit their returns, and on time, than ever before! This is credit to the Sprintax software but also to the amazing Sprintax team, who are a constant source of support, always quick to reply and help troubleshoot any questions that come up. I can’t recommend Sprintax enough. It’s a wonderful solution for making sure that international students fulfil their tax obligations, simplifying a notoriously challenging process and making it almost easy!

I have been working abroad for the past 12 years, in China, then in the USA, and I never knew I could get part of the dividend tax back. Not even KPMG doing my tax mentioned this to me. I found out by chance that Sprintax could help me get 20% back (Switzerland withhold 35%, but I should only pay 15% in the USA). I tried in December 2025, and could get back 20% of all Dividend payment for the past 3 years + current year, 2022, 2023, 2024 and 2025 and I actually just got the payment. They have been super effective and super reactive any time I had a question I got precise feedback within 24h. I’ll keep working with them in the future. My only regret is not to have discovered them earlier, I missed all the money from 2014 till 2021!
