Understanding the Sage Tax Calendar: The Basics

The sage tax calendar is a built-in feature within Sage Payroll that maps out all critical HMRC deadlines, submission windows, and payroll events across the full tax year. It runs from 6 April 2025 to 5 April 2026 and gives payroll managers a clear, structured view of everything they need to action each month.

Think of it as your payroll roadmap. Instead of keeping mental notes or relying on paper reminders, Sage organises every important date in one place so nothing slips through the cracks.

The calendar covers:

• Monthly and weekly payroll processing deadlines
• Real Time Information (RTI) submission dates
• P60 and P11D filing windows
• PAYE payment deadlines to HMRC
• National Insurance and tax code update notifications
• Year-end and new tax year rollover tasks

Key Dates in the Sage Tax Calendar 25/26

The sage tax calendar 25/26 is packed with important milestones. Here is a breakdown of what to expect across the year:

April 2025 — New Tax Year Begins

This is the busiest month on any payroll manager's calendar. The new tax year begins on 6 April 2025, and there is a lot to do before and after that date.

• Update employee tax codes based on HMRC P9 notifications
• Apply new National Insurance thresholds and rates
• Update the National Living Wage and National Minimum Wage rates
• Check student loan thresholds and repayment plan changes
• Ensure your Sage software is updated to reflect 2025/26 rates

If you are unsure how to apply these changes correctly, call +1-844-341-4437 and a Sage payroll expert will walk you through every update step by step.

May 2025 — P60 Deadline

By 31 May 2025, every employee who was on your payroll at 5 April 2025 must receive their P60. Sage Payroll generates P60s automatically from your year-end data, making this process quick and painless.

July 2025 — P11D Submissions

If you provide employees with benefits in kind — company cars, private medical insurance, or other perks — you must submit P11D forms to HMRC by 6 July 2025. Sage supports P11D preparation within its payroll suite.

Monthly Obligations (Throughout the Year)

Every single month, payroll managers must:

• Process payroll and submit Full Payment Submissions (FPS) on or before payday
• Submit Employer Payment Summaries (EPS) where applicable
• Pay PAYE and NI to HMRC by the 19th (cheque) or 22nd (electronic payment) of each month

The sage payroll tax calendar 2025/26 keeps all of these dates visible so you are never caught off guard.

March 2026 — Year-End Preparation

By late March, you should be preparing for year-end. This includes:

• Reviewing employee records for accuracy
• Identifying any outstanding adjustments
• Running your final payroll of 2025/26
• Submitting your final FPS marked as the last submission of the year

The Sage Payroll New Tax Year Checklist: What to Do Before 6 April

Preparation is everything when it comes to payroll. The sage payroll new tax year checklist is a structured list of tasks Sage recommends completing before and just after the new tax year begins. Working through this list ensures your payroll runs accurately from day one of 2025/26.

Before 6 April 2025

• Back up your current payroll data — always create a backup before making any changes
• Install the latest Sage Payroll update — the new tax year update includes all updated rates and thresholds
• Process your final payroll of 2024/25 — ensure all employees have been paid and RTI submissions are complete
• Clear any outstanding payments — resolve any corrections or outstanding HMRC payments before the year closes

After 6 April 2025

• Apply new tax codes — update codes from HMRC's P9 notifications or apply emergency codes where necessary
• Update statutory payment rates — Statutory Sick Pay, Statutory Maternity Pay, and other rates change at the start of each tax year
• Check pension thresholds — auto-enrolment contribution thresholds may change, so verify your pension settings
• Review employee details — confirm addresses, NI numbers, and pay rates are accurate for each team member

How to Set Up the Sage Payroll Tax Calendar 2025/26 in Your Software

Getting the sage payroll tax calendar 2025/26 active in your system is not complicated, but it does require following the right steps in the right order.

Step 1 — Install the Tax Year Update

Sage releases an annual update ahead of each new tax year. This update automatically applies the latest NI rates, tax bands, minimum wage figures, and statutory payment rates. Go to Help > Check for Updates within your Sage Payroll software to download it.

Step 2 — Run the Year-End Process

Before the new year begins, complete Sage's guided year-end wizard. This process closes off 2024/25 records, generates your final submissions, and prepares the system for 2025/26.

Step 3 — Review and Rollover

Once year-end is complete, Sage automatically rolls your employee records into the new tax year. Review each employee's tax code, pay rate, and deductions to confirm everything has carried over correctly.

Step 4 — Activate Calendar Reminders

Within Sage Payroll, navigate to the calendar or reminders section and ensure all key HMRC deadlines are visible and active. Some versions of Sage allow you to sync these dates with Outlook or Google Calendar for added convenience.

Step 5 — Run a Test Payroll

Before processing your first live payroll of 2025/26, run a test calculation to verify that the new rates are being applied correctly across your employee base.

Struggling with any of these steps? Do not waste hours searching through forums. Call +1-844-341-4437 now and speak with someone who can guide you through the setup in real time.

Why the Sage Tax Calendar Is a Must-Have Tool for Payroll Managers

Some payroll managers still rely on external spreadsheets or wall planners to track HMRC deadlines. That approach works until it does not — and by then, penalties may already be on the way.

The sage tax calendar eliminates that risk entirely. Here is why it stands out:

• Everything in one place — no switching between tools or systems
• Automatic updates — Sage updates deadline dates when legislation changes
• Reduces human error — automated reminders mean fewer missed submissions
• Integrates with payroll processing — calendar events are linked directly to payroll actions
• Supports compliance audits — a complete record of submissions and deadlines is maintained automatically
• Accessible anywhere — cloud-based Sage users can access the calendar from any device

For businesses managing multiple pay frequencies — weekly, fortnightly, and monthly — the sage payroll tax calendar 2025/26 is especially valuable. It handles the complexity for you.

Changes in 2025/26 You Must Know About

Each tax year brings legislative updates that directly affect payroll. For 2025/26, key changes include:

• National Living Wage increase — the rate for workers aged 21 and over has risen, as announced by the government
• National Insurance thresholds — secondary NI thresholds have been adjusted, affecting employer contributions
• Statutory payment rate increases — SSP, SMP, and other statutory rates have been updated for 2025/26
• Student loan thresholds — Plan 1, Plan 2, Plan 4, and Postgraduate loan thresholds have all been revised

Sage automatically incorporates all of these changes through the annual tax year update. However, it is worth reviewing each change manually to understand how it affects your specific payroll.

If any of these updates raise questions for your business, call +1-844-341-4437 for personalised guidance on how they apply to your workforce.

Common Mistakes to Avoid When Using the Sage Payroll Tax Calendar

Even experienced payroll professionals make avoidable errors. Here are the most common ones — and how to sidestep them:

Not installing the tax year update on time — Sage releases updates before 6 April. Delay this and your payroll will calculate using outdated rates.

Ignoring P9 tax code notifications — HMRC sends updated tax codes ahead of the new year. Failing to apply them means employees are taxed incorrectly from day one.

Skipping the year-end backup — Always back up before running year-end. If anything goes wrong, you need a restore point.

Missing EPS deadlines — If you have no employees to pay in a given month, you still need to submit an EPS to HMRC. The sage tax calendar 25/26 will remind you of this obligation each month.

Processing payroll before the update is installed — Running payroll before installing the new tax year update will generate figures based on last year's rates. Always update first, then process.
