Employee Starter & Leaver

HMRC requires specific information when an employee starts or leaves your employment. dynamik.app handles this automatically through the FPS (Full Payment Submission).

New Starters

When you add a new employee, go to their profile and fill in the Starter Declaration section:

1. Starter Declaration — Choose A, B, or C based on the employee's circumstances
2. P45 Details (if provided) — Enter the previous tax code, gross pay YTD, and tax deducted YTD from their P45

This information is automatically included in the first FPS submitted for that employee. After the FPS is accepted by HMRC, the starter flag is cleared so it isn't sent again.

What if they don't have a P45?

If the employee doesn't provide a P45, they should complete a Starter Checklist (which replaced the P46). Based on their answers, select the appropriate declaration (A, B, or C) and leave the P45 fields empty.

Leavers

When an employee leaves:

1. Go to their employee record
2. Set the Leaving Date
3. Run their final pay run (their last pay period)

The leaving date is automatically included in the next FPS submission. After HMRC accepts it, the leaver flag is cleared.

Important Notes

• Starter information is only sent once per employee
• Leaver information is only sent once per employee
• If an employee leaves and later returns, they are treated as a new starter again
• Always submit the final FPS before the employee's leaving date to avoid penalties
