Connect your Government Gateway account once, and file VAT returns, Income Tax updates, CIS returns and payroll submissions from inside dynamik.app — no bridging software, no re-typing.

MTD Requirement

VAT-registered businesses must keep digital records and submit VAT returns through MTD-compatible software. Making Tax Digital for Income Tax follows for sole traders and landlords from April 2026, by income band.

Recognition status

dynamik.app is built on HMRC's Making Tax Digital APIs for VAT and Income Tax Self Assessment, and submits directly to HMRC. Our application for HMRC recognition is in progress.
