Every employer running a PAYE scheme must pay the tax and National Insurance owed to HMRC by the 22nd of the month when paying electronically, or by the 19th when paying by post [1]. Since 19 September 2022, a recurring variable direct debit has let employers automate that payment entirely, with HMRC collecting the exact figure declared on the payroll return rather than a fixed sum [2].
The variable direct debit removed a long-standing gap in the way employers settled their monthly liability. Before it existed, an employer could set up a one-off direct debit for a single payment, but nothing that recurred against a changing amount. The result was a manual bank transfer every month, and a late-payment penalty risk whenever that transfer slipped.
This article explains how the monthly PAYE payment cycle works, what the variable direct debit collects and when, how an employer sets one up in the business tax account, and how the deadlines, interest and penalties fit together. It also covers the parts of the PAYE bill the direct debit does and does not cover, and how to change or cancel the mandate once it is running.
Key takeaways
- The electronic payment deadline for PAYE and National Insurance is the 22nd of the month; the postal deadline is the 19th.
- The variable direct debit collects the amount declared on the Full Payment Submission and Employer Payment Summary, and never more than that figure.
- Only the employer can set up the recurring direct debit through the business tax account. Agents cannot create it on a client's behalf.
- Late payment triggers interest at the Bank of England base rate plus 4 percentage points, charged daily from the due date.
- Employers with an average monthly liability below £1,500 can pay quarterly instead of monthly.
How employers pay PAYE to HMRC each month
PAYE is a pay-as-you-earn system, so the tax and National Insurance deducted from employees in a given tax month must reach HMRC shortly after that month closes. The tax month runs from the 6th of one calendar month to the 5th of the next, and the payment covering it falls due in the following weeks [3]. Missing the deadline is one of the most common and most avoidable compliance failures for a small business.
The amount an employer owes each month is not a guess. It is the total of the income tax, employee National Insurance, employer National Insurance, student loan deductions and any other items reported to HMRC through Real Time Information, less any statutory recoveries and the Employment Allowance where claimed [4]. Because that figure moves every month with headcount, overtime and starters and leavers, the payment amount is rarely the same twice.
The monthly and quarterly payment cycle
Most employers pay monthly. An employer whose average monthly PAYE liability is less than £1,500 can instead pay HMRC quarterly, which suits very small or seasonal payrolls [1]. The deadlines mirror the monthly ones: the payment must reach HMRC by the 22nd after the quarter ends for electronic methods, or the 19th by post.
The table below sets out the two cycles side by side.
| Feature | Monthly payers | Quarterly payers |
|---|---|---|
| Eligibility | All employers | Average monthly liability under £1,500 |
| Electronic deadline | 22nd of the following month | 22nd after the quarter ends |
| Postal deadline | 19th of the following month | 19th after the quarter ends |
| Number of payments a year | 12 | 4 |
If the 22nd falls on a weekend or a bank holiday, the payment must clear HMRC's account on the last working day before it, not after [1]. The rule that matters is the cleared-funds date, not the date the money leaves the employer's account, which is why faster payment methods reduce the risk of a technical default [3].
The Accounts Office reference and the period it points at
Every PAYE payment must carry the correct reference or HMRC cannot match it to the right scheme and the right month. The core identifier is the 13-character Accounts Office reference, issued when the PAYE scheme is registered [3]. It appears on the letter confirming the scheme and inside the business tax account.
For a single payment that covers a month other than the current one, HMRC asks for a longer 17-character reference. This adds four digits to the Accounts Office reference to show the tax year and the tax month the payment relates to, so an early or a catch-up payment lands against the correct period [1]. One advantage of the direct debit is that this referencing happens automatically, removing a frequent cause of misallocated payments. Employers running their own payroll can confirm the reference format inside their UK payroll software before making any manual payment.
The variable direct debit for PAYE, explained
The variable direct debit is a recurring mandate that authorises HMRC to collect the PAYE liability each period automatically. It is described by HMRC and by professional bodies as a variable payment plan because the amount collected changes every time, unlike a fixed direct debit for a set monthly figure [2]. The mandate stays in place until the employer cancels it.
Its central safeguard is that HMRC never collects more than the employer has declared. The collection amount is driven by the returns the employer or their payroll agent has already submitted, taking account of any overpayment sitting on the account [2]. An employer therefore keeps full sight of what will be taken, because it equals the figure their own payroll produced.
What the variable direct debit collects
The direct debit collects the charge that Real Time Information has already reported. That means the income tax and National Insurance on the Full Payment Submission, adjusted by anything recovered or reclaimed through the Employer Payment Summary, such as statutory maternity or paternity pay recovery [4]. Where an Employment Allowance claim reduces the employer National Insurance due, the collected amount reflects that reduction too.
Because collection follows the return, the sequence matters. The FPS and any EPS for the month need to be filed before HMRC calculates the collection, so the payroll timetable and the payment timetable are linked [7]. An employer who reports payroll on time and accurately will see a direct debit that matches their records to the penny. This is one reason accountants running many schemes prefer a multi-client payroll dashboard that files RTI on schedule for every client.
When HMRC takes the payment
The collection date sits shortly after the payment deadline rather than on it. HMRC takes the direct debit a few working days after the 22nd, or a few working days after the return is filed if that happens close to the deadline [3]. HMRC notifies the employer of the exact amount before it is collected, so there is advance sight of the figure and time to check it.
This timing has a practical consequence for cash flow. The money leaves the account slightly later than a manual payment made on the 22nd, which gives a modest cash-flow benefit while keeping the payment compliant [2]. Provided the direct debit does not bounce, HMRC treats the payment as made on time and charges no additional interest for the short gap between the deadline and the collection [2].
How to set up a PAYE direct debit
Setting up the mandate happens inside HMRC's online services, in the employer's own business tax account. The bank account used must be one that permits direct debits, and the person setting it up must be an authorised signatory for that account [5].
The step-by-step setup in the business tax account
The employer signs in to HMRC online services with their Government Gateway user ID and password, then completes two-step verification [5]. From the business tax account home screen, they open the PAYE for Employers tile, which shows the employer's liabilities and payments [3].
Inside that screen, a "Set up a Direct Debit" link starts the mandate. The employer enters the business bank account details, confirms the authority to set up a direct debit on that account, and submits [1]. Once HMRC has authorised the mandate, the same link changes to "Manage your Direct Debit", which is where the employer later amends or cancels it. The whole process is self-service and needs no phone call to HMRC.
Why agents cannot set it up
A payroll agent or accountant cannot create the recurring direct debit for a client, even where the agent files all of the client's RTI. The mandate has to be set up by the employer through the employer's own business tax account, because it authorises a collection from the employer's bank account [2].
This split of duties is deliberate. An agent controls the reporting, but only the employer can authorise money to leave the employer's account [2]. In practice the agent files the FPS and EPS that drive the amount, and the employer holds the direct debit that pays it, so the two roles work together across the month. Platforms that expose payroll through an HMRC-recognised payroll API let the agent automate the reporting side while the employer keeps the payment mandate.
Single direct debit versus recurring direct debit
HMRC supports two direct debit models for PAYE, and it helps to keep them distinct. A single direct debit authorises one collection for one payment and then lapses. A recurring direct debit is the variable payment plan that stays live and collects every period automatically [2].
The table below compares the two.
| Feature | Single direct debit | Recurring variable direct debit |
|---|---|---|
| Number of collections | One | Every period until cancelled |
| Amount | The one payment authorised | The declared liability each period |
| Set-up frequency | Every payment | Once |
| Best suited to | An occasional or catch-up payment | Ongoing monthly or quarterly PAYE |
For an employer paying every month, the recurring mandate removes the repeat admin entirely. For an employer who pays rarely, or who wants to settle a single outstanding month, the one-off direct debit is the cleaner choice [1]. An occasional employer producing the odd payment may find an instant payslip generator more proportionate than a standing scheme.
What the direct debit does and does not cover
The variable direct debit covers the PAYE and National Insurance charge reported through RTI. Several related liabilities sit alongside it, and an employer needs to know whether the mandate captures them or whether they need paying separately.
Construction Industry Scheme deductions reported on the same PAYE scheme are collected as part of the same liability, because they form part of the monthly RTI charge [7]. Student loan and postgraduate loan deductions are also part of the declared figure and are collected within the direct debit. Contractors handling subcontractor deductions can read more in the guide to payroll for construction and CIS.
Penalties and interest are different. A late-payment penalty or a late-filing penalty is raised on a separate charge and is not swept up by the variable direct debit. HMRC provides its own dedicated routes, including a direct debit option, for settling a PAYE penalty once it has been issued [6]. An employer who receives a penalty notice therefore has to deal with it separately from the ordinary monthly collection.
Deadlines, interest and penalties for late PAYE
The reason the direct debit matters is that late PAYE is expensive. HMRC charges both interest and, in defined circumstances, penalties, and the two run on different clocks [5].
Late-payment interest
Interest on late-paid PAYE is charged from the due date until the date HMRC receives the money. The rate is set by reference to the Bank of England base rate plus 4 percentage points, and it accrues daily, so even a few days late carries a cost [5]. Because the rate tracks the base rate, the exact percentage changes when the base rate moves, but the plus-4-point formula is fixed [5].
Interest is automatic and is not the same as a penalty. It applies to any amount paid after the due date, regardless of the reason, and cannot usually be appealed on grounds of a reasonable excuse in the way a penalty can [5]. A working variable direct debit removes the risk almost entirely, because HMRC collects on time from the return.
Late-payment and late-filing penalties
Two separate penalty regimes touch PAYE. Late-payment penalties apply when the monthly or quarterly payment is late, and are charged as a percentage of the amount outstanding, rising as the number of defaults in a tax year grows [8]. The first default in a tax year is not counted, which gives a single margin of error, but repeated lateness escalates the charge [8].
Late-filing penalties are separate and attach to the RTI return rather than the payment. They are a flat monthly amount that depends on the number of employees in the scheme, as set out below [8].
| Employees in the PAYE scheme | Monthly late-filing penalty |
|---|---|
| 1 to 9 | £100 |
| 10 to 49 | £200 |
| 50 to 249 | £300 |
| 250 or more | £400 |
HMRC allows a three-day grace period, so an FPS received within three days of the payment date is not penalised, though the return should still be filed on or before the payment date as a rule [8]. Filing penalty notices are issued quarterly, in July, October, January and April [8]. Software that carries the HMRC Recognised badge submits the FPS automatically and dates it correctly, which keeps an employer inside the grace window on every payrun.
Managing, changing or cancelling the direct debit
A live direct debit is not fixed forever. The employer manages it through the same business tax account screen used to set it up, where the "Manage your Direct Debit" link replaces the original set-up link once the mandate is active [1].
From there the employer can change the bank account the collection comes from, or cancel the mandate entirely [3]. A direct debit can also be cancelled directly with the bank, which is a right that applies to any UK direct debit, though cancelling through the business tax account keeps HMRC's records aligned. An employer who cancels the mandate returns to making manual payments and takes back responsibility for hitting the 22nd deadline each month [1].
If a collection is going to fail, for example because funds are short, the employer is better cancelling and arranging an alternative payment before the deadline than letting the direct debit bounce, because a dishonoured direct debit can leave the liability unpaid and exposed to interest [2].
Where payroll software fits
The direct debit only works cleanly when the underlying payroll reporting is right and on time, because HMRC collects exactly what the returns declare [7]. Accurate RTI is therefore the foundation, and the payment mechanism sits on top of it. If the FPS is wrong, the collection is wrong.
This is where the reporting engine and the payment method meet. Modern payroll platforms file the FPS and EPS automatically, calculate the liability that HMRC will collect, and reconcile it against the direct debit taken, so an employer or bureau can see that the figure paid matches the figure due [4]. Businesses running payroll for several entities, or accountants running it for many clients, gain the most from that reconciliation, and can review the options on the small business payroll pages. For year-end reconciliation, the P60 end-of-year checklist sets out how the monthly figures roll up.
Conclusion
The variable direct debit turns PAYE payment from a monthly manual task into an automatic one, and its single most valuable feature is that it can never collect more than the employer has declared. For a small business, the combination of an accurate RTI return and a live direct debit closes off the two ways PAYE goes wrong: a late payment and a mispriced one.
The wider direction of travel is towards payment and reporting that move together, driven by the same payroll data. As more of the compliance work happens automatically inside the software that runs the payroll, the employer's job shifts from making payments to checking that the automated figures are right, which is a smaller and safer task than the one the direct debit replaced.
Frequently asked questions
Can an accountant set up a PAYE direct debit for a client?
No. The recurring variable direct debit must be set up by the employer through the employer's own business tax account, because it authorises collections from the employer's bank account. An agent can file all of the client's RTI returns that drive the amount collected, but only the employer can create and hold the direct debit mandate.
When does HMRC take the PAYE direct debit payment?
HMRC collects the direct debit a few working days after the 22nd of the month, or a few working days after the return is filed if that is close to the deadline. The employer is notified of the exact amount before it is taken, and provided the direct debit does not bounce, the payment is treated as made on time with no extra interest for the short gap.
What happens if the PAYE direct debit fails?
A dishonoured direct debit leaves the PAYE liability unpaid, which can expose the employer to late-payment interest and, if lateness repeats, to a penalty. If an employer knows a collection will fail because of insufficient funds, it is safer to arrange an alternative payment before the deadline than to let the mandate bounce.
Does the direct debit cover PAYE penalties and interest?
No. The variable direct debit collects only the PAYE and National Insurance liability declared through Real Time Information, including student loan and CIS deductions where they run on the same scheme. A late-payment or late-filing penalty is raised as a separate charge and must be paid separately, and HMRC provides a dedicated route, including its own direct debit option, for settling a penalty once it is issued.
