| 4 | Use this skill whenever asked about UK National Insurance Contributions (NIC) for self-employed individuals. Trigger on phrases like "how much NIC do I pay", "Class 2 contributions", "Class 4 NIC", "national insurance self-employed", "NIC calculation", "state pension qualifying years", "NIC deferment", "voluntary Class 2", "HMRC NIC payment", or any question about UK NIC obligations for a self-employed client. Also trigger when classifying bank statement transactions showing HMRC NIC debits, Self Assessment NIC payments, or Class 2 direct debits. This skill covers Class 2 voluntary contributions, Class 4 profit-based rates, thresholds, payment schedule, bank statement pattern classification, interaction with employment Class 1, deferment, state pension entitlement, and edge cases. ALWAYS read this skill before touching any UK NIC-related work. |

| 39 | **Conservative defaults:** |
| 40 | |
| 41 | | Ambiguity | Default | |
| 42 | |---|---| |
| 43 | | Unknown tax year | Ask -- rates differ between 2024-25 and 2025-26 | |
| 44 | | Unknown employment status | Ask -- dual status affects annual maximum cap | |
| 45 | | Unknown profit level | Do not compute -- profits are required | |
| 46 | | Unknown whether client wants voluntary Class 2 | Recommend if profits below SPT and client needs qualifying years | |
| 47 | | Unknown state pension record | Flag for reviewer | |
| 48 | | Unknown age (state pension age) | Ask -- over state pension age = no Class 4 | |
| 49 | |
| 50 | --- |
| 51 | |
| 52 | ## Section 2 -- Required inputs and refusal catalogue |
| 53 | |
| 54 | ### Required inputs |
| 55 | |
| 56 | **Minimum viable** -- tax year, employment status (sole self-employed or dual), and net self-employment profits. |
| 57 | |
| 58 | **Recommended** -- bank statements showing HMRC Self Assessment payments, prior year SA302 tax calculation, state pension record printout. |
| 59 | |
| 60 | **Ideal** -- complete SA100/SA103 return data, P60 from employment (if dual status), NI record from gov.uk. |
| 61 | |
| 62 | ### Refusal catalogue |
| 63 | |
| 64 | **R-UK-NIC-1 -- Non-resident or overseas client.** *Trigger:* client is non-UK resident or has complex international arrangements. *Message:* "NIC for non-resident or overseas clients involves complex rules under EU/bilateral social security agreements. Escalate to a qualified UK practitioner." |
| 65 | |
| 66 | **R-UK-NIC-2 -- Special categories.** *Trigger:* client is a mariner, share fisherman, volunteer development worker, or religious minister. *Message:* "Special NIC provisions apply to this category. Escalate to a qualified practitioner." |
| 67 | |
| 68 | **R-UK-NIC-3 -- Deferment computation.** *Trigger:* client requests Class 1 deferment across multiple employments. *Message:* "Class 1 deferment requires HMRC application (form CA72A) and case-specific earnings analysis. Flag for reviewer." |
| 69 | |
| 70 | --- |
| 71 | |
| 72 | ## Section 3 -- Payment pattern library |
| 73 | |
| 74 | This is the deterministic pre-classifier for bank statement transactions related to NIC. When a transaction matches a pattern below, apply the treatment directly. |
| 75 | |
| 76 | **How to read this table.** Match by case-insensitive substring on the counterparty/reference. NIC payments always EXCLUDE from any VAT classification -- they are statutory personal obligations. |
| 77 | |
| 78 | ### 3.1 HMRC Self Assessment payments (include Class 4 + optional Class 2) |
| 79 | |
| 80 | | Pattern | Treatment | Notes | |
| 81 | |---|---|---| |
| 82 | | HMRC, HM REVENUE, HM REVENUE & CUSTOMS | EXCLUDE -- tax/NIC payment | Self Assessment payments include income tax + Class 4 NIC + voluntary Class 2 | |
| 83 | | HMRC SELF ASSESSMENT | EXCLUDE -- SA payment | Combined tax and NIC | |
| 84 | | HMRC NDDS, HMRC SHIPLEY | EXCLUDE -- SA payment | HMRC processing centres | |
| 85 | | SELF ASSESSMENT, SA PAYMENT | EXCLUDE -- SA payment | Generic SA reference | |
| 86 | |
| 87 | ### 3.2 Class 2 direct debits (voluntary -- separate from SA) |
| 88 | |
| 89 | | Pattern | Treatment | Notes | |
| 90 | |---|---|---| |
| 91 | | HMRC NIC, HMRC CLASS 2 | EXCLUDE -- voluntary Class 2 | Monthly or quarterly direct debit for Class 2 | |
| 92 | | NATIONAL INSURANCE, NAT INS | EXCLUDE -- NIC payment | Generic NI reference | |
| 93 | | NIC DIRECT DEBIT, NIC D/D | EXCLUDE -- Class 2 DD | Voluntary Class 2 via direct debit | |
| 94 | |
| 95 | ### 3.3 HMRC payments via bank transfer |
| 96 | |
| 97 | | Pattern | Treatment | Notes | |
| 98 | |---|---|---| |
| 99 | | HMRC CUMBERNAULD | EXCLUDE -- SA/NIC payment | HMRC Accounts Office reference | |
| 100 | | 1025 (followed by UTR) | EXCLUDE -- SA payment | HMRC Self Assessment payment reference format (1025 + 10-digit UTR) | |
| 101 | |
| 102 | ### 3.4 Student loan and other SA components (NOT NIC) |
| 103 | |
| 104 | | Pattern | Treatment | Notes | |
| 105 | |---|---|---| |
| 106 | | STUDENT LOAN, SLC | EXCLUDE -- student loan repayment | Not NIC -- see uk-student-loan-repayment skill | |
| 107 | | HMRC (large combined payment) | EXCLUDE -- combined SA | May include income tax + Class 4 + Class 2 + student loan; cannot split from bank statement alone | |
| 108 | |
| 109 | ### 3.5 Employer Class 1 (payroll -- not self-employed NIC) |
| 110 | |
| 111 | | Pattern | Treatment | Notes | |
| 112 | |---|---|---| |
| 113 | | SALARY, WAGES (incoming credit) | Not NIC | Employment income -- Class 1 deducted at source by employer | |
| 114 | | EMPLOYER NIC | Not self-employed NIC | Employer's Class 1 obligation, not the client's self-employed NIC | |
| 115 | |
| 116 | --- |
| 117 | |
| 118 | ## Section 4 -- Worked examples |
| 119 | |
| 120 | Six bank statement classifications showing NIC-related transactions for a hypothetical UK self-employed software consultant. |
| 121 | |
| 122 | ### Example 1 -- Self Assessment balancing payment (combined tax + NIC) |
| 123 | |
| 124 | **Input line:** |
| 125 | `31.01.2027 ; HMRC SELF ASSESSMENT ; DEBIT ; SA BALANCING PAYMENT ; -4,200.00 ; GBP` |
| 126 | |
| 127 | **Reasoning:** |
| 128 | Matches "HMRC SELF ASSESSMENT" (pattern 3.1). This is the 31 January balancing payment for tax year 2025-26. Includes income tax, Class 4 NIC, and possibly Class 2 voluntary. Cannot split NIC from income tax on the bank statement alone. Exclude from VAT. The SA302 tax calculation will show the NIC breakdown. |
| 129 | |
| 130 | **Classification:** EXCLUDE -- SA payment (combined tax and NIC). Request SA302 to determine NIC component. |
| 131 | |
| 132 | ### Example 2 -- Payment on account (31 July) |
| 133 | |
| 134 | **Input line:** |
| 135 | `31.07.2026 ; HMRC NDDS ; DEBIT ; PAYMENT ON ACCOUNT ; -2,100.00 ; GBP` |
| 136 | |
| 137 | **Reasoning:** |
| 138 | Matches "HMRC NDDS" (pattern 3.1). This is the second payment on account for 2025-26, due 31 July 2026. Includes 50% of prior year Class 4 liability and income tax. Exclude from VAT. |
| 139 | |
| 140 | **Classification:** EXCLUDE -- SA payment on account. |
| 141 | |
| 142 | ### Example 3 -- Voluntary Class 2 direct debit |
| 143 | |
| 144 | **Input line:** |
| 145 | `15.03.2026 ; HMRC NIC ; DEBIT ; CLASS 2 NIC MAR ; -15.17 ; GBP` |
| 146 | |
| 147 | **Reasoning:** |
| 148 | Matches "HMRC NIC" (pattern 3.2). Amount approximately £3.50/week x 4.33 weeks = £15.17 monthly. This is a voluntary Class 2 payment via direct debit. Client has profits below SPT and is paying voluntarily for state pension qualifying years. |
| 149 | |
| 150 | **Classification:** EXCLUDE -- voluntary Class 2 NIC. Not deductible from profits (Class 2 is not a trading expense). |
| 151 | |
| 152 | ### Example 4 -- Employment salary credit (not NIC) |
| 153 | |
| 154 | **Input line:** |
| 155 | `28.02.2026 ; ACME LTD SALARY ; CREDIT ; FEB SALARY ; +3,200.00 ; GBP` |
| 156 | |
| 157 | **Reasoning:** |
| 158 | This is employment income received. Class 1 NIC has already been deducted by the employer at source. This is NOT a self-employment NIC payment. Do not classify as NIC. |
| 159 | |
| 160 | **Classification:** NOT NIC -- employment income. Class 1 deducted at source. |
| 161 | |
| 162 | ### Example 5 -- Large SA payment (combined with student loan) |
| 163 | |
| 164 | **Input line:** |
| 165 | `31.01.2027 ; HM REVENUE & CUSTOMS ; DEBIT ; SELF ASSESSMENT ; -8,500.00 ; GBP` |
| 166 | |
| 167 | **Reasoning:** |
| 168 | Matches "HM REVENUE & CUSTOMS" (pattern 3.1). Large SA payment that likely combines income tax + Class 4 NIC + possibly Class 2 + student loan repayment. Cannot split components from bank statement. Need SA302 for breakdown. |
| 169 | |
| 170 | **Classification:** EXCLUDE -- combined SA payment. Request SA302 for NIC/tax/student loan split. |
| 171 | |
| 172 | ### Example 6 -- HMRC refund (overpayment) |
| 173 | |
| 174 | **Input line:** |
| 175 | `15.04.2027 ; HMRC ; CREDIT ; SA REPAYMENT ; +650.00 ; GBP` |
| 176 | |
| 177 | **Reasoning:** |
| 178 | This is a CREDIT from HMRC -- a repayment of overpaid SA (may include overpaid NIC). Exclude from VAT. The SA302 will show the breakdown. |
| 179 | |
| 180 | **Classification:** EXCLUDE -- SA refund. Not taxable income. Request SA302 for breakdown. |
| 181 | |
| 182 | --- |
| 183 | |
| 184 | ## Section 5 -- Tier 1 rules |
| 185 | |
| 186 | ### Rule 1 -- Class 4 formula (2025-26) |
| 187 | |
| 188 | ``` |
| 189 | Class 4 NIC = (min(profits, £50,270) - £12,570) x 6% + max(profits - £50,270, 0) x 2% |
| 190 | ``` |
| 191 | |
| 192 | If profits <= £12,570, Class 4 = £0. |
| 193 | |
| 194 | ### Rule 2 -- Class 2 is voluntary from 6 April 2024 |
| 195 | |
| 196 | Self-employed with profits >= SPT (£6,845 in 2025-26) are treated as paid automatically (zero-rate credit). No action needed. Profits < SPT: must pay voluntarily (£3.50/week) to get a qualifying year. |
| 197 | |
| 198 | ### Rule 3 -- Class 4 is based on CURRENT year profits |
| 199 | |
| 200 | Unlike Malta SSC, UK Class 4 NIC is calculated on the same year's profits as reported on the SA return. |
| 201 | |
| 202 | ### Rule 4 -- Payment schedule (via Self Assessment) |
| 203 | |
| 204 | | Payment | Due Date | What | |
| 205 | |---|---|---| |
| 206 | | First payment on account | 31 January during tax year | 50% of prior year Class 4 liability | |
| 207 | | Second payment on account | 31 July after tax year end | 50% of prior year Class 4 liability | |
| 208 | | Balancing payment | 31 January following tax year end | Remaining Class 4 (and Class 2 if voluntary) | |
| 209 | |
| 210 | ### Rule 5 -- Employed AND self-employed |
| 211 | |
| 212 | Class 1 continues on employment income. Class 4 due on self-employment profits above LPL. Both apply simultaneously. Annual maximum cap checked by HMRC automatically. |
| 213 | |
| 214 | ### Rule 6 -- Over state pension age |
| 215 | |
| 216 | No Class 4 liability. No Class 2 needed. Must still file SA return for income tax. |
| 217 | |
| 218 | ### Rule 7 -- Multiple self-employments |
| 219 | |
| 220 | Profits from all self-employments are aggregated for Class 4. |
| 221 | |
| 222 | ### Rule 8 -- Losses |
| 223 | |
| 224 | Zero or negative profits: no Class 4. Voluntary Class 2 may still be paid for state pension. |
| 225 | |
| 226 | ### Rule 9 -- State pension qualifying years |
| 227 | |
| 228 | 35 qualifying years for full new state pension (£230.25/week in 2025-26). 10 years minimum. Class 2 is the cheapest way to build years (£182/year vs Class 3 at £923/year). |
| 229 | |
| 230 | ### Rule 10 -- NIC is NOT tax-deductible |
| 231 | |
| 232 | Class 2 and Class 4 NIC are NOT deductible business expenses. They are personal statutory obligations. |
| 233 | |
| 234 | --- |
| 235 | |
| 236 | ## Section 6 -- Tier 2 catalogue |
| 237 | |
| 238 | ### T2-1 -- Deferment (multiple employments) |
| 239 | |
| 240 | **Trigger:** Client has two employments and expects combined Class 1 to exceed annual maximum. |
| 241 | **Action:** Flag for reviewer. Client may apply on form CA72A to defer Class 1 in secondary employment. |
| 242 | |
| 243 | ### T2-2 -- First year with overlap relief / basis period |
| 244 | |
| 245 | **Trigger:** Client started trading mid-year; basis period allocation unclear under 2024-25 reform. |
| 246 | **Action:** Flag for reviewer to confirm basis period allocation for Class 4. |
| 247 | |
| 248 | ### T2-3 -- Backfilling NI gaps for state pension |
| 249 | |
| 250 | **Trigger:** Client wants to pay voluntary contributions for prior years. |
| 251 | **Action:** Can go back up to 6 years. Class 2 if eligible as self-employed in those years; otherwise Class 3. Flag for reviewer to check NI record. |
| 252 | |
| 253 | ### T2-4 -- Examiners, moderators, foster carers |
| 254 | |
| 255 | **Trigger:** Employment status is ambiguous. |
| 256 | **Action:** Flag for reviewer. Check contract terms for employment vs self-employment. |
| 257 | |
| 258 | ### T2-5 -- Non-resident with UK self-employment |
| 259 | |
| 260 | **Trigger:** Client is non-UK resident but has UK self-employment profits. |
| 261 | **Action:** Escalate -- complex NIC rules for non-residents. |
| 262 | |

| 307 | ## Section 8 -- Bank statement reading guide |
| 308 | |
| 309 | ### How NIC payments appear on UK bank statements |
| 310 | |
| 311 | **Self Assessment payments (combined tax + NIC):** |
| 312 | - Description: "HMRC SELF ASSESSMENT", "HM REVENUE & CUSTOMS", "HMRC NDDS", "HMRC SHIPLEY" |
| 313 | - Timing: 31 January (1st POA + balancing), 31 July (2nd POA) |
| 314 | - Amount: Combined income tax + Class 4 + optional Class 2 + student loan |
| 315 | - Cannot split NIC from tax on bank statement -- need SA302 |
| 316 | |
| 317 | **Voluntary Class 2 direct debit:** |
| 318 | - Description: "HMRC NIC", "HMRC CLASS 2", "NIC D/D" |
| 319 | - Timing: Monthly (around 15th) or quarterly |
| 320 | - Amount: Approximately £15/month or £45/quarter (£3.50/week) |
| 321 | |
| 322 | **HMRC refunds:** |
| 323 | - Description: "HMRC", "SA REPAYMENT" |
| 324 | - Direction: CREDIT (incoming) |
| 325 | - May include NIC overpayment component |
| 326 | |
| 327 | **Key identification tips:** |
| 328 | 1. Most self-employed NIC is embedded within SA payments -- you cannot isolate it from the bank statement |
| 329 | 2. Only voluntary Class 2 via direct debit appears as a separate NIC-labelled transaction |
| 330 | 3. The SA302 tax calculation is the authoritative source for the NIC breakdown |
| 331 | 4. Payments on account are based on prior year -- actual NIC may differ |
| 332 | |
| 333 | --- |
| 334 | |
| 335 | ## Section 9 -- Onboarding fallback |
| 336 | |
| 337 | If the client provides only a bank statement: |
| 338 | |
| 339 | 1. **Scan for HMRC debits** -- identify all outgoing payments matching Section 3 patterns |
| 340 | 2. **Identify SA payment dates** -- 31 Jan and 31 Jul payments are SA payments on account |
| 341 | 3. **Flag combined nature:** "HMRC Self Assessment payments include income tax, Class 4 NIC, optional Class 2, and student loan repayments combined. The bank statement alone cannot isolate the NIC component. Please provide the SA302 tax calculation or the SA100 return for breakdown." |
| 342 | 4. **Identify separate Class 2 DD** -- small monthly debits (~£15) labelled "HMRC NIC" are voluntary Class 2 |
| 343 | |
| 344 | --- |
| 345 | |
| 346 | ## Section 10 -- Reference material |
| 347 | |
| 348 | ### Rates comparison (2024-25 vs 2025-26) |
| 349 | |
| 350 | | Item | 2024-25 | 2025-26 | |
| 351 | |---|---|---| |
| 352 | | Class 2 weekly rate | £3.45 | £3.50 | |
| 353 | | Class 2 annual | £179.40 | £182.00 | |
| 354 | | SPT | £6,725 | £6,845 | |
| 355 | | Class 4 main rate | 6% | 6% | |
| 356 | | Class 4 additional rate | 2% | 2% | |
| 357 | | LPL | £12,570 | £12,570 | |
| 358 | | UPL | £50,270 | £50,270 | |
| 359 | |
| 360 | ### Test suite |
| 361 | |
| 362 | **Test 1:** 2025-26, self-employed only, profits £30,000. -> Class 4 = £1,045.80. Class 2 treated as paid. Total = £1,045.80. |
| 363 | |
| 364 | **Test 2:** 2025-26, self-employed only, profits £80,000. -> Class 4 = £2,856.60. Total = £2,856.60. |
| 365 | |
| 366 | **Test 3:** 2025-26, profits £10,000. -> Class 4 = £0. Profits > SPT, Class 2 treated as paid. Total = £0. |
| 367 | |
| 368 | **Test 4:** 2025-26, profits £5,000, voluntary Class 2. -> Class 4 = £0. Class 2 = £182.00. Total = £182.00. |
| 369 | |
| 370 | **Test 5:** 2025-26, profits -£3,000, voluntary Class 2. -> Class 4 = £0. Class 2 = £182.00. Total = £182.00. |
| 371 | |
| 372 | **Test 6:** 2025-26, employed (£45,000 salary, Class 1 via payroll) + self-employed profits £20,000. -> Class 4 = £445.80. Annual max checked by HMRC. |
| 373 | |
| 374 | **Test 7:** 2025-26, age 69, profits £40,000. -> Class 4 = £0 (over state pension age). Total = £0. |
| 375 | |
| 376 | **Test 8:** 2024-25, profits £30,000. -> Class 4 = £1,045.80. Class 2 treated as paid (profits > SPT £6,725). |
| 377 | |
| 378 | ### Prohibitions |
| 379 | |
| 380 | - NEVER compute Class 4 without confirming the tax year |
| 381 | - NEVER tell a client they must pay Class 2 -- it is voluntary since 6 April 2024 |
| 382 | - NEVER tell a client with profits below SPT that they automatically get a qualifying year |
| 383 | - NEVER apply Class 4 rates to employment income |
| 384 | - NEVER ignore the annual maximum NIC cap for dual-status clients |
| 385 | - NEVER advise on deferment without confirming all employment income sources |
| 386 | - NEVER present NIC figures as definitive for dual-status clients |
| 387 | - NEVER assume Class 2 is treated as paid for clients with profits below SPT |
| 388 | - NEVER advise on NIC for non-resident clients without escalating |
| 389 | |
