Ex-Wise operators who found errors in their own tax returns just raised $2M to fix Britain's self-assessment problem — TFN

London-based Record OS has raised $2M in a pre-seed round led by Episode 1, with angel backing from Wise, Revolut, Deliveroo, and Alphabet, to build a self-assessment and make-tax-digital platform.

Founded by former Wise operators Dhruv Chadha and José Luis De La Peña, the startup integrates AI-driven filing with mandatory review by a qualified tax professional.

The launch aligns with Making Tax Digital. Since April 2026, self-employed workers and landlords earning over £50,000 must submit quarterly digital updates to HMRC. The threshold will decrease to £30,000 in 2027 and £20,000 in 2028.

Dhruv Chadha, who has worked in finance at Google, Wise, and Nansen, found a mistake in his self-assessment return while testing the platform, even with professional help.

“When I found an error in my own tax return while testing the platform, I was shocked – I’d paid for professional help, I work in finance, and I was still left wondering whether everything had actually been done correctly. That simply shouldn’t still be the case in 2026,” Chadha says.
