TL;DR: Scrib🐮's M4 Submission Guide walks you through filing with HMRC step by step — document checklist, portal navigation, fees, and processing times — so your submission is complete and correct the first time.
Filing documents with government agencies requires knowing exactly what to submit, in what format, through which portal, and within what timeframe. Incorrect or incomplete submissions are rejected — causing delays, additional fees, and in some cases, penalties.
UK document filings involve specific agency requirements that differ from what you might expect if you have only filed in other jurisdictions. The HMRC (https://www.gov.uk/register-employer) has its own portal, its own document format requirements, and its own processing timeline. Understanding these requirements before you begin prevents costly rework.
Scrib🐮's M4 Submission Guide for UK provides a step-by-step walkthrough of the HMRC filing process, integrated with the documents you have prepared through M1 Templates or M2 Guided Prep.
What M4 covers for UK filing:
UK employers must register with HMRC before their first pay day. Registration is done through HMRC's online employer registration service (https://www.gov.uk/register-employer). Processing takes approximately 5 working days, resulting in an employer PAYE reference and an Accounts Office reference. These references are required for running payroll and reporting to HMRC. After registering, choose payroll software — HMRC's Basic PAYE Tools is free and suitable for employers with fewer than 10 employees (https://www.gov.uk/payroll-software/free-payroll-software). Commercial payroll software (Xero, QuickBooks, Sage) provides more automation for growing teams.
Step-by-step filing process:
HMRC employer registration steps: (1) Create a Government Gateway account (if not already registered). (2) Register online at https://www.gov.uk/register-employer — you need the employer's UTR (Unique Taxpayer Reference) if the employer is a limited company. (3) Receive your employer PAYE reference (takes approximately 5 working days). (4) Set up payroll software before first pay day. (5) Complete an auto-enrolment assessment for each new employee from Day 1 of employment. (6) Declare your compliance to The Pensions Regulator within 5 months of your staging date.
Document preparation integration:
Documents prepared through Scrib🐮's M1 Template and M2 Guided Prep modules are exported in the format compatible with HMRC requirements. The M4 Submission Guide shows where each document maps to the relevant online form field or upload requirement, eliminating the guesswork of matching prepared documents to government forms.
After submission:
The M4 guide covers what to do after submission: how to track the status of your application, how to respond to any information requests from the agency, and the post-registration steps that must be completed once registration is confirmed. The M5 Dashboard tracks the expected response date and any post-registration deadlines automatically.

DIY filing: Filing directly with HMRC without guidance is feasible — these are public processes. The challenge is knowing exactly which fields to complete, which documents to attach, and what to do if the application is rejected. The M4 guide reduces the risk of rejection by ensuring your submission is complete and correctly formatted.
Formation agents: Company formation agents charge fees to handle filings on your behalf. Their value is in removing the administrative burden. Scrib🐮's M4 guide enables self-filing at a fraction of the agent fee, while keeping you in control of the process.
Scrib🐮: The M4 Submission Guide integrates with the documents you have prepared through M1 and M2, maps each document to the relevant filing requirement, and covers the post-registration steps. At $149/month, the same pass covers all three menus across all seven countries.

Q: Does Scrib🐮 submit my filing to HMRC on my behalf?
No. Scrib🐮 prepares your documents and guides you through the filing process. You submit the application directly through the HMRC portal (https://www.gov.uk/register-employer). This keeps you in control of your filing and ensures you receive all confirmation and correspondence from the agency directly.
Q: What if my application is rejected by HMRC?
The M4 Submission Guide explains the most common reasons for rejection and how to respond to rejection notices. The M3 AI Assistant can also help you understand what a specific rejection reason means and what to do to address it. For complex rejection situations, consult a professional familiar with HMRC filing requirements.
Q: Are the filing fees shown in the guide current?
Filing fees change periodically. The M4 Submission Guide shows fees as of the date of the guide, with a link to HMRC's current fee schedule (https://www.gov.uk/register-employer). Always verify the current fee directly with HMRC before submitting your application.
