Automate document chasing| When | Deadline / event | Why accountants chase documents |
|---|---|---|
| 31 January | Self Assessment online payment | Balancing payment and payments on account for the previous tax year (where applicable). |
| 5 April | Tax year end | End of the UK personal tax year — common trigger for SA document collection. |
| 6 April | New tax year starts | Start of the new personal tax year; update client record requests. |
| 31 May | P60 distribution | Employers issue P60s — often requested for Self Assessment evidence. |
| 6 July | P11D filing deadline | Benefits in kind reporting to HMRC for employers. |
| Quarterly | VAT return periods | Deadlines depend on the client’s VAT stagger group — chase records before each period end. |
| 9 months after year-end | Company accounts filing (typical) | Companies House filing window varies — confirm per company; chase year-end packs early. |
| Ongoing | AML ID refresh | Review passport and address proof expiry before reviews — not a single HMRC date. |
