UK HMRC Time to Pay Arrangement: Self-Service Online, Phone Route, 7.5% Interest and Missed-Payment Consequences for 2026/27
HMRC Time to Pay (TtP) is the official UK installment-arrangement framework that allows taxpayers struggling to meet a tax bill on time to spread the balance over monthly payments. Used by hundreds of thousands of Self Assessment taxpayers, PAYE employers and VAT-registered businesses every year, TtP is the standard cooperative route HMRC expects when there is genuine payment difficulty. The 2020 introduction of Self-Service TtP via gov.uk Personal Tax Account allowed Self Assessment debts up to £30,000 to be settled online in minutes without any phone call — a major operational improvement retained after COVID. For larger debts and other taxes (PAYE, Corp Tax, VAT) the phone route via HMRC Business Payment Support 0300 200 3835 is required, typically agreeing 12-36 month installment plans on routine cases. Interest still accrues at the official late-payment rate (7.5% in 2025/26) — TtP avoids the 5% surcharge penalties, not interest. Missed payments under a TtP arrangement trigger immediate full demand and HMRC enforcement action including distraint and credit-rating damage. This pillar guide covers eligibility, application routes online and by phone, interest calculation, the relationship with Self Assessment penalty surcharges, missed-payment consequences, and when bankruptcy / IVA / Debt Relief Order alternatives become more appropriate than TtP — with worked examples and practical guidance for 2026/27.
What is HMRC Time to Pay?
HMRC Time to Pay (TtP) is the official installment-arrangement framework for UK taxpayers who cannot pay a tax bill in full by the due date. It applies across Self Assessment income tax, employer PAYE/National Insurance, Corporation Tax, VAT and most HMRC-administered taxes. Instead of paying the full balance by the deadline (and incurring penalties), the taxpayer spreads payment over monthly Direct Debit installments — typically 12 months for routine SA cases, up to 36 months for larger business debts.
The legal framework. TtP is a discretionary HMRC power under Section 108 Finance Act 2009 and equivalent provisions for each tax. It is granted on negotiated terms — HMRC can decline if the proposed arrangement is unrealistic — but in practice the great majority of well-prepared TtP applications for routine cash flow problems are agreed. HMRC operates published policies on TtP and trains officers explicitly to negotiate rather than refuse where genuine difficulty exists.
What TtP avoids. The headline benefit is avoiding the 5% surcharge penalty applied to unpaid SA income tax at 30 days past due, with further surcharges at 6 months and 12 months. Equivalent default surcharges exist for VAT (15% per quarter in the worst case under the old default-surcharge regime; replaced by points-based penalties from January 2023). For PAYE, late-payment penalties scale with frequency of defaults. TtP also avoids HMRC enforcement action — distraint, CCJ registration, third-party debt orders — provided installments are met on time. Interest still accrues, but penalty cost and enforcement impact are eliminated.
Self-Service TtP Online
Self-Service TtP for Self Assessment was introduced in October 2020 as a COVID response and retained as a permanent feature. It allows eligible taxpayers to set up an installment plan online via gov.uk Personal Tax Account without any phone call, officer interview or proof of hardship. Eligibility is strict:
- Total Self Assessment debt £30,000 or less (raised from £10,000 during COVID, retained at £30,000 since)
- Application within 60 days of the original payment deadline (extended from 30 days during COVID, retained)
- All Self Assessment tax returns filed and up to date
- No other current Time to Pay arrangements in place
- No other tax debts in arrears with HMRC
- Ability to repay within a maximum of 12 months
- Direct Debit set up from a UK bank account
Setup process. Log into gov.uk Personal Tax Account at gov.uk/personal-tax-account; navigate to Self Assessment; click "Set up a payment plan" or "Pay in installments"; confirm the debt amount; choose monthly installment amount (system suggests an even split over up to 12 months); select Direct Debit bank account and chosen day of month; confirm. HMRC immediately sends written confirmation by email and post; first DD is normally taken on the next chosen date.
Self-Service TtP has been used by an estimated 800,000-1,000,000 SA taxpayers since its 2020 introduction — a substantial operational shift compared with the previous phone-only model. The system is fully automated and operates 24/7. No officer review or approval is required for eligible cases.
Phone Route for Larger Debts and Other Taxes
For Self Assessment debts ABOVE £30,000, for any TtP outside the 60-day window, for PAYE/Corp Tax/VAT, or where Self-Service eligibility is not met, the phone route is required. The principal number is HMRC Business Payment Support 0300 200 3835, open Mon-Fri 8am-6pm. The VAT-specific line is 0300 200 3700.
The phone call. An HMRC officer will ask about: (a) your reason for difficulty; (b) your current income and expenditure (Standard Financial Statement format for larger debts); (c) your assets and ability to use them; (d) your prior payment history with HMRC; (e) the monthly affordability of various installment levels. The officer is trained to negotiate cooperatively rather than refuse; cases of genuine cash flow difficulty with realistic monthly capacity are almost always agreed.
Phone-arranged TtP can extend beyond the 12-month Self-Service limit. Typical durations: 12 months for routine SA over £30k; 18-24 months for business VAT or Corp Tax with one-off difficulty; up to 36 months for larger debts with strong forward viability. Very large arrangements (£500k+) may require security in the form of a legal charge over property. Documentation may be requested: bank statements (3-6 months), accounts (last filed and management), supplier and customer evidence for cash flow gaps. Prepare in advance — the call is more efficient when you have these to hand.
Eligibility Conditions
For HMRC to agree TtP, you must demonstrate ALL of:
- Genuine inability to pay in full — not merely inconvenience or preference. HMRC distinguishes between "can't pay" and "won't pay"; the former qualifies, the latter does not.
- Realistic repayment plan — proposed monthly installments must be sustainable given your evidenced income and essential expenditure. Unrealistic plans (e.g., paying 80% of net income) are declined.
- All tax returns filed up to date — HMRC will not agree TtP while any return is outstanding. File first, negotiate second.
- No history of multiple broken TtP — one prior default is forgivable; persistent defaults are not.
- Direct Debit mandate — non-negotiable. HMRC does not accept manual payments under TtP.
- For very large debts — possible security over property or other assets; possible compliance review.
Failure of the "genuine inability" test usually means HMRC will reject TtP and demand immediate full payment, with normal enforcement following if the demand is unpaid. Failure of the realistic-plan test usually means HMRC will counter-propose a shorter installment period or larger monthly amount. Cases where total expenditure consistently exceeds total income are usually escalated by HMRC to recommend formal insolvency procedures (IVA, DRO, bankruptcy) instead of TtP.
Interest at 7.5%
HMRC charges interest on outstanding tax balances at the official late-payment rate, set as Bank of England base rate + 2.5%. In May 2026 this stands at 7.5% (4.5% base + 2.5% margin), down from the 7.75% peak of early 2024 with the modest base-rate reductions of late 2025. Interest accrues daily from the original due date until the full balance is paid, INCLUDING during a TtP arrangement.
What TtP saves. TtP avoids the 5% surcharge penalties applied to unpaid SA income tax at 30 days, 6 months and 12 months past due. On a £10,000 debt, the 30-day surcharge alone is £500; if unpaid for 12 months the total surcharges reach 15% = £1,500. TtP eliminates all surcharges provided installments are met. Interest at 7.5% over the same 12 months on £10,000 averaging £5,000 outstanding ≈ £375 — much less than the avoided surcharges.
The interest rate has risen sharply since 2022. Early 2022: 2.6%. Mid-2023: 6.5%. Early 2024 peak: 7.75%. Mid-2024 onwards: 7.5%. The rate adjusts with each Bank of England rate move, normally with a 1-2 week implementation lag. The repayment interest rate paid BY HMRC on overpaid tax is set as base rate - 1%, currently 3.5% in 2025/26 — a 4 percentage point asymmetric spread that costs UK taxpayers hundreds of millions per year in aggregate. The Treasury reviews this spread periodically; criticism from the Office of Tax Simplification and the Treasury Select Committee has not yet produced reform.
TtP by Tax Type
| Tax | Route | Self-Service? | Typical duration |
|---|---|---|---|
| Self Assessment income tax | Online for ≤£30k; phone for >£30k or outside 60-day window | Yes (£30k cap) | Up to 12 months online; up to 36 months phone |
| PAYE/Employer NI | Phone 0300 200 3835 | No | 12-24 months typical |
| Corporation Tax | Phone 0300 200 3835 | No | 12-24 months typical |
| VAT | Phone 0300 200 3700 | No | 6-12 months typical; HMRC less flexible |
| CGT (60-day property return) | Phone 0300 200 3835 | No | 12 months typical |
VAT is treated more strictly because it is "tax collected from customers" rather than business profit — HMRC's political stance is that VAT defaults are more serious than CT or PAYE defaults, and durations are typically shorter. Repeated VAT defaults within 12 months can escalate to compliance review and possible registration cancellation in extreme cases. Single-period VAT TtP for a one-off cash flow gap is routinely agreed, but persistent quarterly issues prompt HMRC to push the business towards restructuring or insolvency advice.
Missed-Payment Consequences
A missed Direct Debit payment under TtP triggers immediate breach of the arrangement. The standard escalation:
- Automated reminder within 7-14 days — text and letter; brief window to contact HMRC and resume.
- If unresponsive — full outstanding debt becomes immediately due in one lump sum; installment privilege withdrawn.
- Penalties reinstated — 5% surcharges at 30 days, 6 months, 12 months from original due date applied retrospectively (less any periods covered by valid TtP).
- Enforcement — HMRC commences collection: County Court Judgment registration, distraint (taking control of goods), third-party debt orders against bank accounts, deduction from earnings via PAYE code adjustment.
- Insolvency referral — for very large or persistent cases, HMRC may petition for bankruptcy (personal) or winding-up (business) — the Bankruptcy Petition route is HMRC's ultimate enforcement weapon, used roughly 4,000-6,000 times per year.
The single most important practical rule: if you anticipate missing a payment, contact HMRC IMMEDIATELY before the missed payment date. HMRC can usually agree to: temporarily reduce the installment for a defined period; skip one payment with the missed amount added at the end of the plan; restructure the whole arrangement. Only repeated unresponsive defaults trigger full enforcement. Proactive communication is treated very differently from silent default.
Worked £8,000 SA Example
Scenario. Self-employed taxpayer with January 31st SA balancing payment of £6,000 plus first July payment-on-account of £2,000, total £8,000 due. Cash flow gap due to late client payments. Wants to spread over 12 months via Self-Service TtP.
Setup. Log into gov.uk PTA before 1 April (within 60 days of January 31st deadline). Apply for installment plan online. Choose 12 equal monthly Direct Debits at £667/month, starting 1 February. Confirmed in 15 minutes.
Interest accrual. Interest at 7.5% daily on outstanding balance from 1 February (the day after the original 31 January deadline). Average outstanding balance over the 12 months: ~£4,000 (starts at £7,333 after the first DD, declines linearly to £667 at month 12). Total interest = £4,000 × 7.5% × 1 year ≈ £300.
Total cost. £8,000 principal + £300 interest = £8,300. Final payment slightly higher than the £667 monthly average to capture accrued interest, or paid as a separate final balance.
Comparison without TtP. If the £8,000 was simply left unpaid until paying eventually: 30-day surcharge £400 (5%) + 6-month surcharge £400 + 12-month surcharge £400 = £1,200 in penalty surcharges, plus the same interest at 7.5%. Total cost ~£9,200-£9,500 without TtP. TtP saves approximately £900-£1,200 on this scenario.
Documentation. Keep the HMRC confirmation email of the TtP arrangement and all DD-collection notifications. If a dispute later arises, this evidence shows the arrangement was active and prevents retrospective penalty application.
When to Use Alternatives
TtP is the right tool for a CASH FLOW problem — a temporary mismatch between income timing and tax due, with underlying ability to pay over 12-36 months. It is the WRONG tool for a SOLVENCY problem — total debts exceed total realistic repayment capacity. The main alternatives:
- Debt Management Plan (DMP) — informal arrangement with all creditors via a debt advice charity (StepChange, National Debtline, PayPlan). Suitable for moderate total debts (£10k-£40k) across multiple creditors where individual settlements are impractical. Does NOT bind HMRC who can decline.
- Debt Relief Order (DRO) — formal insolvency for low-income, low-asset individuals. 2024 reforms: debt cap raised to £50,000, asset cap to £4,000, vehicle cap to £4,000. £90 fee, 12-month restriction. Available where total debts ≤£50k, assets ≤£4k, surplus income ≤£75/month. HMRC debts ARE included in DRO.
- Individual Voluntary Arrangement (IVA) — formal arrangement supervised by Insolvency Practitioner. Typical structure: 60 months of repayments at affordable amount, remaining unsecured debt written off at end. Affects credit rating for 6 years from approval. HMRC must approve (75% by value of creditors voting). Costs typically £4,000-£6,000 IP fees, paid from the monthly contributions.
- Bankruptcy — formal court process for very large debts or where IVA/DRO not viable. £680 fee. Most unsecured debts written off after 1 year. Severe credit-rating impact for 6 years. Some assets may be sold (home equity, second car). HMRC frequently petitions for bankruptcy in unpaid-tax cases above ~£5,000.
- Members' Voluntary Liquidation (MVL) / Creditors' Voluntary Liquidation (CVL) — for limited companies. MVL is solvent winding-up (positive equity); CVL is insolvent (negative equity). HMRC is usually the largest creditor in distressed UK SMEs.
Free initial advice is available from StepChange (0800 138 1111), National Debtline (0808 808 4000), Citizens Advice and the Money and Pensions Service. For business cases, an Insolvency Practitioner consultation (often free for the first 30 minutes) helps choose between TtP, CVA (Company Voluntary Arrangement), Administration, CVL or solvent restructuring. Engage early — options narrow sharply once HMRC enforcement action commences.
