Data protection · PDPA

Your data, your control. The mechanics of compliance, made tangible.

The Personal Data Protection Act No. 9 of 2022 gave Sri Lankans the right to know, correct, port and delete. Here is how TaxWise honours each of those rights in product.

What happens to your data, end to end.

Collection
Minimisation at the form

We only ask for fields the IRD return requires, or fields a relief specifically needs to be substantiated.

Storage
Encrypted at rest, sharded by tenant

AES-256-GCM per-column encryption. Customer-specific keys held in AWS KMS Singapore.

Processing
In Sri Lanka & Singapore only

Compute lives in ap-south-1 (Mumbai) with hot standby in ap-southeast-1 (Singapore). Data does not transit other regions.

Sharing
IRD-only, on your authorisation

We transmit returns to the IRD e-Filing system only after you have clicked 'Submit'. No other recipient receives your return data.

Retention
Seven-year statutory window

Tax data retained for the IRD's seven-year audit window, then deleted or anonymised within 30 days.

Disposal
Crypto-shred plus tombstone

Encryption keys destroyed first; tombstoned record sweeps purge backing storage within 30 days.
