42**Conservative defaults:**
43 
44| Ambiguity | Default |
45|---|---|

48| Income expected to drop | Pay per notice -- do NOT reduce without CFR approval |
49| Rental income in prior year tax | Exclude rental income taxed at 15% final WHT from PT basis |
50| Overpayment treatment | Credit against next year (not automatic refund) |

54## Section 2 -- Required inputs and refusal catalogue
55 
56### Required inputs
57 
58**Minimum viable** -- the prior year TA24 assessed tax liability (the net tax payable after credits) OR the CFR-issued PT notice (Vorauszahlungsbescheid equivalent). One of these is mandatory.
59 
60**Recommended** -- current year of assessment, any PAYE or withholding tax deducted at source in the current year, the client's TIN.
61 
62**Ideal** -- full TA24 from the prior year, any CFR PT notice received, bank statements showing prior PT payments, any correspondence about PT reductions.
63 
64**Refusal policy if minimum is missing -- HARD STOP.** Without the prior year TA24 tax liability or a CFR PT notice, provisional tax cannot be computed. Do not estimate from income figures.
65 
66### Refusal catalogue
67 
68**R-MT-PT-1 -- Group companies or partnership PT.** Trigger: client asks about PT for a company or partnership. Message: "This skill covers provisional tax for self-employed individuals only. Company and partnership PT obligations have different rules. Please consult a warranted accountant."
69 
70**R-MT-PT-2 -- Non-resident PT obligations.** Trigger: client is non-resident or asks about PT for non-residents. Message: "Non-resident provisional tax obligations are outside the scope of this skill. Please consult a warranted accountant."
71 
72**R-MT-PT-3 -- PT penalty disputes.** Trigger: client asks about disputing PT penalties or CFR enforcement. Message: "Penalty disputes require legal analysis. Please escalate to a warranted accountant or tax advocate."
73 
74---
75 
76## Section 3 -- Payment pattern library
77 
78This is the deterministic pre-classifier for bank statement transactions. When a debit matches a pattern below, classify it as a provisional tax payment. Do not second-guess.
79 
80### 3.1 CFR provisional tax debits
81 
82| Pattern | Treatment | Notes |
83|---|---|---|
84| CFR, COMMISSIONER FOR REVENUE | PT payment | Match with April/August/December timing to identify which instalment |
85| INLAND REVENUE MALTA | PT payment | Legacy name, same authority |
86| PROVISIONAL TAX, PROV TAX, PT PAYMENT | PT payment | Explicit description |
87| TAX INSTALMENT, TAX INST | PT payment | Generic instalment label |
88 
89### 3.2 Timing-based identification
90 
91| Debit date range | Likely instalment | Confidence |
92|---|---|---|
93| 15 April -- 10 May | 1st instalment (20%) | High if payee is CFR |
94| 15 August -- 15 September | 2nd instalment (30%) | High if payee is CFR |
95| 1 December -- 31 December | 3rd instalment (50%) | High if payee is CFR |
96| Any other date to CFR | Late payment or adjustment | Flag for reviewer |
97 
98### 3.3 Related but NOT provisional tax
99 
100| Pattern | Treatment | Notes |
101|---|---|---|
102| VAT DEPARTMENT, VAT PAYMENT | EXCLUDE from PT | VAT payment, separate obligation |
103| SSC, SOCIAL SECURITY, CESOP | EXCLUDE from PT | Social security contribution |
104| FSS, FINAL SETTLEMENT | EXCLUDE from PT | PAYE final settlement system |
105| PENALTY, INTEREST CFR | EXCLUDE from PT | Late payment charge, not PT principal |
106 
107### 3.4 Bank transfer references
108 
109| Reference pattern | Treatment | Notes |
110|---|---|---|
111| PT followed by year (e.g., PT2025) | PT payment for that year | Common bank transfer reference format |
112| YA followed by year | PT payment for that year of assessment | Alternative reference format |
113| INSTALMENT 1, INSTALMENT 2, INSTALMENT 3 | PT payment, specific instalment | Self-identified |
114

116 
117## Section 4 -- Worked examples
118 
119### Example 1 -- Standard three-instalment computation
120 
121**Input:** Prior year TA24 tax liability = EUR 9,000.
122 
123**Computation:**
124 
125| Instalment | Percentage | Amount | Due date |
126|---|---|---|---|
127| 1st | 20% | EUR 1,800 | 30 April 2025 |
128| 2nd | 30% | EUR 2,700 | 31 August 2025 |
129| 3rd | 50% | EUR 4,500 | 21 December 2025 |
130| **Total** | **100%** | **EUR 9,000** | |
131 
132### Example 2 -- Reconciliation with final assessment (underpayment)
133 
134**Input:** Total PT paid = EUR 8,000. Final TA24 tax liability = EUR 11,500.
135 
136**Output:** Balance due = EUR 11,500 - EUR 8,000 = EUR 3,500. Due with TA24 filing by 30 June following the year of assessment.
137 
138### Example 3 -- Reconciliation with final assessment (overpayment)
139 
140**Input:** Total PT paid = EUR 10,000. Final TA24 tax liability = EUR 7,200.
141 
142**Output:** Overpayment = EUR 2,800. Client may request refund (written application to CFR, 6-12 months processing) or accept credit against next year's PT.
143 
144### Example 4 -- Rental income excluded from PT basis
145 
146**Input:** Prior year TA24: EUR 3,000 tax on self-employment income + EUR 1,500 tax on rental income (15% final WHT). Total tax = EUR 4,500.
147 
148**Computation:** PT based on EUR 3,000 only (rental income at 15% final WHT excluded).
149 
150| Instalment | Amount |
151|---|---|
152| 1st (20%) | EUR 600 |
153| 2nd (30%) | EUR 900 |
154| 3rd (50%) | EUR 1,500 |
155 
156### Example 5 -- Late payment penalty
157 
158**Input:** 1st instalment of EUR 1,800 due 30 April. Paid 15 July (2.5 months late).
159 
160**Computation:** Interest = EUR 1,800 x 0.75% x 3 months (rounded up) = EUR 40.50. Additional 10% penalty may apply at CFR discretion.
161 
162### Example 6 -- Bank statement classification
163 
164**Input line:** `30.04.2025 ; CFR ONLINE PAYMENT ; DEBIT ; PT2025 INST 1 ; -1,800.00 ; EUR`
165 
166**Classification:** Provisional tax payment, 1st instalment for YA 2025. Not a deductible expense for VAT or income tax purposes -- this is a tax payment, not a business cost.
167 
168---
169 
170## Section 5 -- Computation rules
171 
172### 5.1 Standard computation (prior-year basis)
173 
174The computation basis is always the prior year assessed tax liability from the most recent TA24, after credits, minus any tax deducted at source.
175 
176```
177prior_year_tax = TA24_assessed_tax - tax_credits - WHT_at_source
178PT_instalment_1 = prior_year_tax x 20%
179PT_instalment_2 = prior_year_tax x 30%
180PT_instalment_3 = prior_year_tax x 50%
181total_PT = prior_year_tax x 100%
182```
183 
184Do NOT divide by three equally. The split is always 20/30/50.
185 
186### 5.2 Year-end reconciliation
187 
188```
189balance_due = final_tax_liability - total_PT_paid - WHT_at_source
190if balance_due > 0: additional payment required with TA24 (by 30 June)
191if balance_due < 0: overpayment -- refund or credit
192```
193 
194### 5.3 Special rules for first year and new businesses
195 
196For the first year of self-employment with no prior TA24: PT is based on the penultimate year's tax. If no penultimate year assessment exists, the CFR sets a minimum PT amount administratively. Flag for reviewer.
197 
198### 5.4 Excluded income
199 
200Income subject to final withholding tax (e.g., 15% on rental income, 15% on certain interest) is NOT included in the PT computation base. PT applies only to income subject to progressive rates.
201 
202---
203 
204## Section 6 -- Penalties and interest
205 
206### 6.1 Late payment interest
207 
208| Element | Rate |
209|---|---|
210| Interest rate | 0.75% per month (9% per annum) |
211| Runs from | Due date of each instalment |
212| Maximum | No statutory cap -- accrues until paid |
213| Additional penalty | CFR may impose 10% on amounts outstanding after final due date |
214 
215### 6.2 Interest computation
216 
217```
218interest = unpaid_amount x 0.75% x months_overdue
219```
220 
221Interest accrues per instalment independently. A missed April instalment accrues 8+ months of interest by December.
222 
223---
224 
225## Section 7 -- Adjustments and reductions
226 
227If the taxpayer expects current year income to be significantly lower than the prior year, they may apply in writing to CFR to reduce PT instalments. The application must include evidence (reduced contracts, cessation of activity) and should be submitted before the relevant instalment due date.
228 
229Risk: if actual tax exceeds the reduced PT, interest and penalties apply on the shortfall.
230 
231Flag for reviewer before advising any PT reduction.
232 
233---
234 
235## Section 8 -- Edge cases
236 
237**EC1 -- No prior year TA24 assessment available.** Client has been self-employed for 3 years but never filed a TA24. CFR may issue estimated assessments. PT should be based on the latest CFR-issued assessment. If none exists, CFR minimum applies. Flag for reviewer -- client must regularise filing history urgently.
238 
239**EC2 -- Prior year resulted in zero tax.** Tax liability = EUR 0. PT = EUR 0. No instalments required. However, if current year income is expected to exceed the personal allowance, voluntary PT payments are prudent.
240 
241**EC3 -- Mid-year switch from employment to self-employment.** First year of self-employment. Penultimate-year rule applies. PAYE covers the employment portion. PT applies only to the self-employment income. Flag for reviewer.
242 
243**EC4 -- Rental income at 15% final WHT.** Rental income taxed at 15% final WHT is excluded from the PT computation. PT applies only to income subject to progressive rates.
244 
245**EC5 -- Overpayment carried forward but client wants refund.** Client must submit written request to CFR. Processing time 6-12 months. Flag for reviewer for cash flow advice.
246 
247**EC6 -- Client ceases self-employment mid-year.** Apply to CFR to cancel remaining PT instalments. Final TA24 reconciles actual liability.
248 
249**EC7 -- CFR PT notice differs from client calculation.** The CFR notice prevails unless the client appeals. Pay the CFR-stated amount and query separately. Paying less triggers penalties on the shortfall.
250 
251**EC8 -- Foreign source income with DTR.** PT is based on the NET tax from the prior TA24, which already factors in double taxation relief. Flag for reviewer to confirm DTR availability in the current year.
252 
253**EC9 -- Late filing of prior year TA24.** Use the latest available assessed year as the basis. File the overdue TA24 urgently. CFR may issue revised PT notices once processed.
254

278**Expected:** 1st = EUR 1,800 (30 Apr). 2nd = EUR 2,700 (31 Aug). 3rd = EUR 4,500 (21 Dec). Total = EUR 9,000.
279 
280### Test 2 -- Zero prior year tax

299 
300### Test 7 -- Rental income excluded
301**Input:** Prior year: EUR 3,000 tax on SE income + EUR 1,500 on rental (15% WHT). Total = EUR 4,500.
302**Expected:** PT on EUR 3,000 only. 1st = EUR 600, 2nd = EUR 900, 3rd = EUR 1,500.
303 
304---
305 
306## Prohibitions
307 
308- NEVER compute PT without the prior year TA24 tax liability or a CFR PT notice
309- NEVER use current year estimated income as the basis -- PT is always prior year
310- NEVER advise skipping PT payments because income is expected to drop -- must apply to CFR
311- NEVER divide by three equally -- the split is always 20/30/50
312- NEVER include income subject to final WHT (rental at 15%) in the PT basis
313- NEVER present PT figures as definitive without a CFR notice -- label as estimated
314- NEVER advise on PT penalty disputes without escalating to a warranted accountant
315- NEVER assume overpayment is automatically refunded -- client must apply or accept credit
