To run payroll and accounting around HMRC compliance deadlines you will need to invest in creating structured processes that will streamline and ensure timely payroll submissions, payment of taxes, VAT returns, and statutory filings. For your practices it’s important to stay one step ahead of deadlines to avoid penalties and unnecessary stress for your clients and bad reputation for your practice.
For instance, a practice was facing a new deadline every month related to PAYE submissions, pension contributions, VAT returns, payroll processing, and year-end accounts. The practice was stuck between a constant struggle to meet the deadlines while addressing last-minute client requests.
One time, the client sent payroll information late, which created a chain reaction that affected RTI submissions and payroll processing. While it was resolved, this problem could have been avoided if there had been proper planning.
The practice invested in structures like compliance calendar, automated key workflows, and introduced regular client reminders. The result was fewer last-minute surprises, improved efficiency, and better client service.
In this guide, we’ll explore how accounting practices can plan payroll and accounting activities around HMRC deadlines, reduce payroll compliance risks, and create more efficient workflows.
Understanding HMRC Compliance Deadlines
HMRC compliance is not limited to just tax return filing one a year. When you handle HMRC compliance for your clients, your team of accountants have to deal with multiple deadlines throughout the year, including payroll submissions, tax payments, VAT obligations, and corporation tax requirements.
Some of the most important deadlines include:
PAYE and Payroll Deadlines
Clients operating PAYE must submit payroll information through Real Time Information (RTI) on or before the employees are paid.
Key payroll obligations include:
- Full Payment Submission (FPS)
- Employer Payment Summary (EPS), where applicable
- PAYE and National Insurance payments
- Pension contribution reporting
The PAYE bill must be paid to HM Revenue and Customs (HMRC) by:
- The 22nd of the next tax month, if you pay monthly
- The 22nd after the end of the quarter, if you pay quarterly – for example, 22 July for the 6 April to 5 July quarter
If you pay by cheque through the post, it must reach HMRC by the 19th of the month.
VAT Deadlines
All your clients whose are running businesses and their turnover exceeds £90,000 in a rolling 12-month period will have to submit their VAT returns and make payments as per the reporting schedule.
The deadline for submitting VAT returns online is usually one calendar month and 7 days after the end of an accounting period. This is also the deadline for paying HMRC.
Corporation Tax Deadlines
Companies generally need to:
- Pay Corporation Tax within 9 months and 1 day after their accounting period ends.
- Submit a Corporation Tax Return (CT600) within 12 months of the accounting period end.
Self-Assessment Deadlines
Business owners, directors, and self-employed individuals may also have personal tax obligations requiring careful planning. Missing any of these deadlines can result in penalties, interest charges, and unnecessary administrative burdens.
Common Challenges Practices Face in Payroll and Accounting Compliance

Even after knowing the importance of maintaining compliance with HMRC payroll and accounting deadlines, we have found practices struggling with meeting them due to multiple challenges. Let’s understand each of the common challenges.
Managing Multiple Deadlines
One of the biggest hurdles in the path of maintaining compliance with HMRC deadlines is keeping track of numerous filing and payment dates.
You will have to manage:
- Weekly payrolls
- Monthly payrolls
- Quarterly VAT returns
- Annual accounts
- Corporation Tax returns
- Self-Assessment deadlines
Without advanced planning important dates can be easily missed.
Last-Minute Client Information
You might have missed on deadlines due to delayed communication from your clients.
The client has to provide critical information, such as:
- Payroll changes
- Employee information
- Expense records
- VAT documents
When this information is provided at the last minute, it leaves your accountants with limited time to process the information accurately.
Manual Processes
It will be hard to believe, but we have found a few practices still relying on spreadsheets and manual workflows. It increases the risk of:
- Data entry errors
- Missed deadlines
- Duplicate work
- Compliance mistakes
As client numbers grow, these inefficiencies become more significant.
Resource Constraints
Recruitment of accounting talent in the UK is a big challenge, and getting expert talent is neither easy nor reasonable. Many practices operating small accounting teams and try to manage increasing compliance demands. As a result, staff get overwhelmed during peak seasons, which increases the chances of human errors.
Constant Regulatory Changes
UK payroll and tax regulations are constantly evolving.
Keeping up with:
- PAYE changes
- National Insurance updates
- Pension requirements
- HMRC guidance
requires continuous monitoring and training.
Step-by-Step Plan to Align Payroll and Accounting with HMRC Deadlines
The only way to overcome the above challenges in meeting compliance with HMRC payroll and accounting deadlines is proactive planning.
Here’s a practical framework that accounting practices can follow.
Step 1: Create a Master Compliance Calendar
Create a calendar that centralises all the deadlines. It should include:
- Payroll processing dates
- RTI submission deadlines
- PAYE payment dates
- VAT deadlines
- Corporation Tax deadlines
- Accounts filing dates
- Self-Assessment deadlines
A centralised calendar provides visibility across the entire practice, leaving no scope for confusion.
Step 2: Build Internal Deadlines Before HMRC Deadlines
It would be counterproductive to wait until the official deadline; it will only lead to rushed work and increased chances of errors. Instead, establish internal deadlines several days before submission dates.
For example:
- Client payroll information due by the 20th
- Payroll processing is completed by the 25th
HMRC submissions completed before the official deadline. This creates a buffer for unexpected issues.
Step 3: Standardise Client Communication
Most compliance problems occur because your clients don’t know what information you provide and when.
Therefore, create standard communication processes such as:
- Monthly payroll reminders
- VAT document requests
- Year-end information checklists
Through clear communication, delays are avoided and accuracy improves.
Step 4: Automate Where Possible
Automate all the tasks that can be automated, especially repetitive ones, so that the workload is reduced.
Modern payroll and accounting systems can automate:
- Payroll calculations
- RTI submissions
- Client reminders
- Payroll reporting
- Workflow tracking
Various studies show that payroll automation reduces manual processing time while helping organisations improve compliance consistency.
Step 5: Conduct Regular Compliance Reviews
Don’t conduct reviews to identify issues at the end of the year. Conduct frequent reviews, quarterly one to ensure:
- Payroll records remain accurate
- VAT obligations are met
- Tax liabilities are understood
- Compliance risks are identified early
Such regular reviews support better decision-making and minimise surprises.
Step 6: Develop Contingency Plans
Always build some contingency plan to cater to unexpected events that can disrupt compliance processes.
Examples include:
- Staff absences
- Software issues
- Client delays
- Cybersecurity incidents
A well-written contingency plan helps maintain continuity when challenges arise.
Tools and Resources to Simplify Compliance
Handling so many deadlines along with catering to clients’ demand for reports, services, and insights is not humanly possible. You will need tools and additional resources for handling compliance effectively.
Payroll Software
A modern payroll software can automate:
- PAYE calculations
- RTI submissions
- Pension processing
- Payslip generation
Cloud Accounting Platforms
Solutions such as Xero, QuickBooks, and Sage provide:
- Real-time financial visibility
- Automated bank feeds
- VAT reporting functionality
Workflow Management Systems
Many practices have started using practice management software, which can help you in:
- Tracking deadlines
- Allocate tasks
- Monitor progress
- Improve accountability
HMRC Resources
Official HMRC sites frequently publish updates on tax rates, deadline changes, guidance, and compliance information. These sites must be monitored to avoid non-compliance.
Combining technology with structured processes creates a stronger compliance framework.
Real-World Example: How Practices Avoid Penalties
An accounting practice managing payroll and bookkeeping of 30 SME clients was meeting their deadlines using spreadsheets and email reminders.
As the client base grew, problems emerged:
- Late client submissions
- Missed follow-ups
- Increased stress around payroll periods
The practice implemented:
- A central compliance calendar
- Automated client reminders
- Cloud payroll software
- Monthly workflow reviews
Within six months, payroll processing became more predictable, deadline compliance improved, and staff spent less time chasing information. More importantly, the practice reduced the risk of penalties and improved client satisfaction.
This example demonstrates that compliance success often comes down to planning and process improvements rather than simply working harder.
