How it works
Four steps. Then you are done.
No spreadsheets, no jargon, no shoebox of receipts. Oazy does the heavy lifting and only asks when it genuinely needs you.
AI categorises everything
Each transaction is classified against UK tax rules, allowable versus disallowable, capital versus revenue, with reasoning logged.
Confirm the unclear bits
Low-confidence items become a simple checklist. The AI never guesses on the big or unusual stuff, so you stay in control.

Submit straight to HMRC and Companies House, or grab a ready-to-file pack. Your filing history lives in your dashboard.

Good to know
Questions, answered.
Is my bank data safe?
Yes. We connect through FCA-regulated Open Banking providers, encrypt everything (AES-256 at rest, TLS in transit), and do not store raw bank feeds longer than needed for your return. Every account uses MFA, and access is strictly read-only.
Do you file directly with HMRC?
You can file straight to HMRC and Companies House through our integrations, or download a ready-to-file pack and submit it yourself. Your choice.
What if the AI gets a transaction wrong?
It will not guess on anything it is unsure about. Low-confidence and unusual items always become a quick checklist for you to confirm, and nothing is filed without your consent.
Do I have to re-enter everything next year?
No. Your Digital Passport keeps your personal and company details saved, so returning users just reconnect their bank and file fast.
Can Oazy handle cash income and receipts?
Yes. Alongside your bank transactions, you can snap a photo of any receipt and Oazy reads it, categorises it, and applies the deduction automatically, so cash-in-hand income and expenses are captured too. During setup we ask whether your business takes cash so nothing is missed.
