Quarterly workflow that keeps you compliant
MTD for Income Tax requires quarterly updates and an end-of-period statement. Accounted tracks your obligation periods automatically, calculates your figures, and reminds you before each deadline. After you file, Penny starts preparing for the next quarter.
- Automatic obligation period tracking
- Pre-populated quarterly figures from your categorised transactions
- Side-by-side comparison with previous quarters
- End-of-period statement generation at year-end
