Annual adjustments & capital allowances
Once a year, before you finalise: claim capital allowances on equipment and record year-end adjustments for your self-employment. From 2026-27 the main pool writing down allowance is 14%, a new 40% first year allowance covers qualifying plant and machinery, and the zero-emission goods vehicle allowance is withdrawn.
Capital allowances
Replaces all other allowances if claimed.
Year-end adjustments
Year-end final declaration
Once all four quarters are in, finalise the year. This works out your tax and replaces the old Self Assessment return. Due by 31 January.
Other income & reliefs (optional)
Add anything HMRC does not already have. Your salary and bank interest are usually already on your record, so leave those out. Enter the totals for the whole year.
CIS filing details
Your details as a contractor. Needed to verify subcontractors and file the monthly CIS return.
Subcontractors
Verify each one with HMRC before you pay them. The result sets the deduction rate: 0%, 20% or 30%.

Employer Payment Summary (EPS)
The employer-level RTI report, separate from the FPS. Use it to claim Employment Allowance, report a month with no payments, report CIS deductions suffered, or reclaim statutory pay. File it by the 19th of the following tax month.
Period of inactivity (optional)
Tell HMRC in advance that you will pay no one for a run of future months, so it stops expecting an FPS. The start is the 6th of a month, the end the 5th, sent before it starts and no more than 6 months ahead. Leave both blank if not needed.
