Section 2 -- Required inputs and refusal catalogue

Required inputs

Minimum viable -- birth year and employment status. Without birth year, STOP. Do not compute SSC.

Recommended -- prior year net self-employment income (from filed TA24), number of years of self-employment, and whether a TA24 has been filed for the prior year.

Ideal -- DSS annual statement, bank statements showing quarterly SSC debits, prior year TA24 with Box 20 SSC deduction.

Refusal catalogue

R-MT-SSC-1 -- Birth year unknown. Trigger: birth year not provided. Message: "Birth year is mandatory for SSC computation. The maximum contribution cap (SC) differs for persons born before vs on/after 1 January 1962. Cannot proceed without this information."

R-MT-SSC-2 -- SSC arrears computation. Trigger: client has unpaid SSC from prior years. Message: "SSC arrears are computed at current rates (not historical rates) for post-1962 clients, with 1% per month penalties compounding indefinitely. Do not attempt to quantify arrears without a DSS statement. Escalate to a warranted accountant immediately."

R-MT-SSC-3 -- Disability or special exemptions. Trigger: client claims disability exemption, student credited contributions, or pensioner pro-rata reduction. Message: "Exemptions and reduced rates for disability, students, and pensioners require case-specific confirmation from DSS. Escalate to a warranted accountant."

R-MT-SSC-4 -- Group pension arrangements. Trigger: client asks about group pension or occupational scheme interaction with SSC. Message: "Group pension arrangements and their interaction with statutory SSC are outside the scope of this skill. Escalate to a warranted accountant."

Section 3 -- Payment pattern library

This is the deterministic pre-classifier for bank statement transactions related to social security. When a transaction matches a pattern below, apply the treatment directly. Do not second-guess.

How to read this table. Match by case-insensitive substring on the counterparty/reference as it appears in the bank statement. SSC payments always EXCLUDE from any VAT return or revenue/expense classification -- they are statutory personal obligations, not business supplies.

3.1 DSS quarterly debits (Class 2 self-employed)

Pattern	Treatment	Notes
DSS, DEPARTMENT OF SOCIAL SECURITY	EXCLUDE -- SSC payment	Quarterly Class 2 direct debit or bank transfer
SOCIAL SECURITY, SOC SEC	EXCLUDE -- SSC payment	Same
SSC, S.S.C.	EXCLUDE -- SSC payment	Abbreviated reference
CLASS 2, CLASS TWO	EXCLUDE -- SSC payment	Explicit class reference
KONTRIBUZZJONI SOCJALI	EXCLUDE -- SSC payment	Maltese-language reference

3.2 DSS debits appearing on specific Maltese banks

Bank	Typical debit description	Treatment
BOV (Bank of Valletta)	"DSS DIRECT DEBIT" or "DEPT OF SOCIAL SECURITY"	EXCLUDE -- SSC
HSBC Malta	"DEPARTMENT OF SOCIAL SECURITY" or "DSS D/D"	EXCLUDE -- SSC
APS Bank	"DSS" or "SOC SECURITY CONTRIB"	EXCLUDE -- SSC
Lombard Bank	"SOCIAL SECURITY"	EXCLUDE -- SSC
Revolut / Wise	Rare -- DSS debits typically come from local Maltese accounts	If present, EXCLUDE

3.3 Income tax payments (NOT SSC -- do not confuse)

Pattern	Treatment	Notes
CFR, COMMISSIONER FOR REVENUE	EXCLUDE -- income tax, not SSC	Tax payment, not social security
INLAND REVENUE, IRD	EXCLUDE -- income tax	Same
FSS, FINAL SETTLEMENT SYSTEM	EXCLUDE -- employer PAYE/FSS	Not Class 2 SSC
PAYE, PAYER TAX	EXCLUDE -- employer withholding	Not Class 2 SSC

3.4 Salary and payroll (exclude from SSC classification)

Pattern	Treatment	Notes
SALARY, PAGA, WAGES (outgoing)	EXCLUDE -- payroll expense	Not an SSC payment
SALARY, PAGA (incoming)	EXCLUDE -- employment income received	Not an SSC payment

3.5 Pension payments (received -- not SSC contributions)

Pattern	Treatment	Notes
DSS PENSION, PENSJONI	EXCLUDE -- pension income received	Not a contribution payment
OLD AGE PENSION	EXCLUDE -- pension income	Not a contribution

Section 4 -- Worked examples

Six bank statement classifications showing SSC-related transactions from a hypothetical self-employed Maltese IT consultant.

Example 1 -- Standard quarterly SSC debit (BOV)

Input line: 30.04.2026 ; DEPT OF SOCIAL SECURITY ; DEBIT ; Q1 2026 CLASS 2 ; -470.34 ; EUR

Reasoning: Matches "DEPT OF SOCIAL SECURITY" (pattern 3.1). Amount EUR 470.34 = SA minimum quarterly (EUR 1,881.36 / 4). This is the Q1 2026 Class 2 contribution. Exclude from VAT classification. Record as SSC expense deductible in Box 20 of TA24.

Classification: EXCLUDE -- SSC payment. Deductible in TA24 Box 20.

Example 2 -- Mid-range SSC quarterly debit (HSBC)

Input line: 31.07.2026 ; DSS D/D ; DEBIT ; SOCIAL SECURITY CONTRIBUTION ; -750.00 ; EUR

Reasoning: Matches "DSS D/D" (pattern 3.2, HSBC). Amount EUR 750.00 = quarterly payment for SB category (EUR 3,000 annual / 4 = EUR 750). Implies prior year net income of EUR 20,000 (15% x EUR 20,000 = EUR 3,000). Exclude from VAT.

Classification: EXCLUDE -- SSC payment. Deductible in TA24 Box 20.

Example 3 -- CFR tax payment (NOT SSC)

Input line: 30.06.2026 ; COMMISSIONER FOR REVENUE ; DEBIT ; PT 2026 ; -1,200.00 ; EUR

Reasoning: Matches "COMMISSIONER FOR REVENUE" (pattern 3.3). This is a provisional tax payment, NOT an SSC payment. Do not classify as social security. Exclude from VAT. Not deductible as SSC in Box 20 -- this is income tax.

Classification: EXCLUDE -- income tax payment. NOT SSC.

Example 4 -- Salary outgoing (employer payroll, not SSC)

Input line: 28.04.2026 ; JOHN DOE SALARY APR ; DEBIT ; PAGA ; -1,800.00 ; EUR

Reasoning: Matches "PAGA" / salary pattern (3.4). This is a wage payment to an employee, not an SSC contribution. Class 1 employer contributions may also appear separately but are payroll costs, not the client's Class 2 SSC.

Classification: EXCLUDE -- payroll expense. NOT the client's Class 2 SSC.

Example 5 -- Pension income received (not a contribution)

Input line: 05.05.2026 ; DSS PENSION ; CREDIT ; OLD AGE PENSION MAY ; +680.00 ; EUR

Reasoning: Matches "DSS PENSION" (pattern 3.5). This is a pension benefit RECEIVED, not a contribution paid. Do not confuse inbound DSS credits with outbound SSC debits. Exclude from VAT. This is taxable income on the TA24, not a Box 20 deduction.

Classification: EXCLUDE from VAT. Taxable income (not an SSC deduction).

Example 6 -- Ambiguous DSS debit (penalty or arrears)

Input line: 15.09.2026 ; DEPARTMENT OF SOCIAL SECURITY ; DEBIT ; ARREARS PAYMENT ; -2,400.00 ; EUR

Reasoning: Matches "DEPARTMENT OF SOCIAL SECURITY" (pattern 3.1) but the amount is irregular and reference says "ARREARS PAYMENT." This could include penalties (1% per month) compounded on top of unpaid contributions. Cannot separate principal from penalty without a DSS statement. Flag for reviewer.

Classification: EXCLUDE from VAT. Flag for reviewer -- request DSS breakdown to split contribution principal (deductible in TA24 Box 20) from penalty (not deductible).

---

Section 5 -- Tier 1 rules

These rules apply when bank statement data is clear and all required inputs are available. Apply exactly as written.

Rule 1 -- SSC formula

SSC = clamp(prior_year_net_income x 15%, SA_minimum, SC_maximum)

Where:

• SA minimum = EUR 1,881.36/year
• SC maximum (pre-1962) = EUR 3,825.12/year
• SC maximum (post-1962) = EUR 4,362.28/year

Rule 2 -- Birth year determines ONLY the SC maximum

Born before 1 January 1962: SC maximum = EUR 3,825.12. Born on or after 1 January 1962: SC maximum = EUR 4,362.28. Birth year does NOT affect SA minimum or the 15% SB rate.

Rule 3 -- SSC is based on PRIOR year net income

2026 SSC = based on 2025 net income from filed TA24. Not current year estimates.

Rule 4 -- First year or no TA24 filed = SA minimum

First year of self-employment: SA minimum applies as a legislative provision, not just a default. No prior year TA24 filed: SA minimum applies until DSS assessment is made.

Rule 5 -- Minimum always applies

Even at zero income, the SA minimum (EUR 1,881.36) is due once registered. There is no zero-SSC outcome.

Rule 6 -- Full-time employed (Class 1) exempts from Class 2

If the client is a full-time employee paying Class 1 NIC, no Class 2 is due on side income. Class 1 covers everything.

Rule 7 -- SSC is deductible in TA24 Box 20

SSC paid in Year X is deducted from income in Year X's TA24 (Box 20). This reduces taxable income before tax rate application.

Rule 8 -- Payment schedule

Quarter	Period	Due Date
Q1	Jan -- Mar	30 April
Q2	Apr -- Jun	31 July
Q3	Jul -- Sep	31 October
Q4	Oct -- Dec	31 January (following year)

Rule 9 -- Registration threshold

Self-employment income above EUR 910/year triggers SSC registration obligation. Below EUR 910 may be exempt but should still register.

Rule 10 -- Maternity fund (Class 1A) does NOT apply to self-employed

Class 1A (0.3% of gross salary) is employer-only. Do not include in Class 2 calculations.

---

Section 6 -- Tier 2 catalogue

When bank statement data is ambiguous or client circumstances are unclear, flag these situations for reviewer confirmation.

T2-1 -- Dual status ambiguity (employed but also director)

Trigger: Client is a full-time employee but also a director of their own company drawing a director's fee.

Issue: Director fees from a company where the client is NOT a full-time employee may trigger Class 2. If the client is a full-time employee of the same or another company with Class 1 already paid, Class 2 is not due.

Action: Flag for reviewer. Confirm employment contract status and hours before advising.

T2-2 -- TA22 client with multiple part-time income sources

Trigger: Client has two part-time self-employment activities, neither with full-time employment.

Issue: TA22 requires no full-time employment. If both activities are part-time and no full-time employment exists, Class 2 applies. Unclear whether one activity tips into full-time equivalence.

Action: Flag for reviewer.

T2-3 -- Returning self-employed (previously stopped, now restarting)

Trigger: Client was self-employed before, stopped for several years, now restarting.

Issue: SA minimum does NOT automatically apply to returners. SA applies only to genuine first-timers. If no prior year TA24 for self-employment exists, SA applies until assessment.

Action: Flag for reviewer to confirm with DSS.

T2-4 -- SSC arrears from prior years

Trigger: Client has unpaid SSC from previous years.

Issue: DSS can recover up to 5 years. Arrears are calculated at current rates (not historical rates) for post-1962 clients. 1% per month penalty compounds indefinitely.

Action: Do not attempt to quantify arrears without a DSS statement. Escalate to warranted accountant immediately.

T2-5 -- Mid-year switch from employment to self-employment

Trigger: Client was employed until mid-year, then became self-employed.

Issue: Class 1 stops when employment ends. Class 2 starts when self-employment begins. First-year SA minimum applies for the self-employment period. Quarterly SSC payments due from the relevant quarter onward.

Action: Flag for reviewer to confirm start date and pro-rata application.

T2-6 -- Students, pensioners, and disability exemptions

Trigger: Client may qualify for credited contributions, pro-rata reduced rate, or exemption.

Issue: These categories require case-specific DSS confirmation.

Action: Flag for reviewer. Do not apply exemptions without DSS confirmation.

Section 8 -- Bank statement reading guide

How SSC debits appear on Maltese bank statements

BOV (Bank of Valletta):

• Description: "DSS DIRECT DEBIT" or "DEPT OF SOCIAL SECURITY" or "DEPARTMENT OF SOCIAL SECURITY"
• Timing: End of month following quarter (30 Apr, 31 Jul, 31 Oct, 31 Jan)
• Amount: Quarterly figure (annual / 4)

HSBC Malta:

• Description: "DSS D/D" or "DEPARTMENT OF SOCIAL SECURITY" or "SOC SEC CONTRIB"
• Timing: Same quarterly cycle
• Amount: Quarterly figure

APS Bank:

• Description: "DSS" or "SOC SECURITY CONTRIB" or "SOCIAL SECURITY"
• Timing: Same quarterly cycle

Key identification tips:

1. SSC debits are always outgoing (DEBIT), never credits
2. They recur quarterly with consistent amounts (unless the client changed income bracket)
3. The amount should be divisible by 4 from a round annual figure, OR exactly EUR 470.34 (SA minimum quarterly)
4. Do not confuse with CFR/Inland Revenue debits (income tax) or FSS debits (employer PAYE)
5. Arrears payments may appear as irregular lump sums with "ARREARS" in the reference

---

Section 9 -- Onboarding fallback

If the client provides only a bank statement and no other information:

1. Scan for DSS debits -- identify all outgoing payments matching Section 3 patterns
2. Sum annual SSC paid -- total all DSS debits in the year
3. Reverse-engineer the category:
   • If total approximately EUR 1,881.36 -> SA minimum (income <= EUR 12,543.72 or first year)
   • If total between EUR 1,881.36 and EUR 3,825.12 -> SB (15% rate band)
   • If total approximately EUR 3,825.12 -> SC pre-1962 maximum
   • If total approximately EUR 4,362.28 -> SC post-1962 maximum
4. Flag for reviewer: "SSC classification derived from bank statement amounts only. Birth year and prior year income have not been independently verified. Reviewer must confirm before filing TA24 with Box 20 deduction."

Section 10 -- Reference material

Calculation examples (2026)

Prior Year Net Income	Birth Year	Category	Annual SSC	Quarterly
EUR 8,000	1990	SA	EUR 1,881.36	EUR 470.34
EUR 0	1990	SA	EUR 1,881.36	EUR 470.34
EUR 20,000	1990	SB	EUR 3,000.00	EUR 750.00
EUR 20,000	1955	SB	EUR 3,000.00	EUR 750.00
EUR 50,000	1990	SC (post-1962)	EUR 4,362.28	EUR 1,090.57
EUR 50,000	1955	SC (pre-1962)	EUR 3,825.12	EUR 956.28

Self-occupied vs Self-employed

• Self-occupied: trades, businesses, professions (accountant, plumber, shop owner). Entitled to pension + short-term benefits (sickness, injury, maternity).
• Self-employed: income from rents, investments, capital gains. Entitled to pension only.
• Both pay the same 15% Class 2 rate with the same min/max caps.

Penalties

Penalty	Rate
Late payment	1% per month on outstanding amount
Non-registration	All unpaid contributions + penalties
Arrears lookback	DSS can claim up to 5 years of unpaid SSC
Arrears rate (post-1962)	Calculated at CURRENT rates, not rates when originally due

Test suite

Test 1: Born 1985, prior year net income EUR 20,000, not first year. -> SB. Annual = EUR 3,000.00. Quarterly = EUR 750.00.

Test 2: Born 1958, prior year net income EUR 60,000, not first year. -> SC (pre-1962). Annual = EUR 3,825.12. Quarterly = EUR 956.28.

Test 3: Born 1975, prior year net income EUR 60,000, not first year. -> SC (post-1962). Annual = EUR 4,362.28. Quarterly = EUR 1,090.57.

Test 4: Born 1990, prior year net income EUR 5,000, not first year. -> SA. Annual = EUR 1,881.36. Quarterly = EUR 470.34.

Test 5: Born 1988, first year, no prior TA24. -> SA (first year). Annual = EUR 1,881.36. Quarterly = EUR 470.34.

Test 6: Full-time employee paying Class 1, side income EUR 8,000. -> NO Class 2 due. Class 1 covers all.

Test 7: Born 1992, registered self-employed, net income EUR 0. -> SA. Annual = EUR 1,881.36.

Test 8: Client paid EUR 3,000 SSC in 2025, preparing 2025 TA24. -> EUR 3,000 in Box 20.

Prohibitions

• NEVER compute SSC without knowing the client's birth year
• NEVER use current year income -- SSC is always based on PRIOR year net income
• NEVER tell a client they owe zero SSC because their income is low -- minimum always applies once registered
• NEVER apply SA minimum to a returning self-employed without reviewer confirmation
• NEVER advise on SSC arrears without a DSS statement -- do not estimate
• NEVER conflate Class 1 and Class 2 -- they are entirely separate obligations
• NEVER include maternity fund (Class 1A) in Class 2 calculations
• NEVER present SSC figures as definitive -- always label as estimated and direct client to their DSS statement
• NEVER compute SSC penalties without escalating to a warranted accountant
