First year, no penultimate year	Flag for reviewer -- minimum PT per CFR applies
Income expected to drop	Pay per notice -- do NOT reduce without CFR approval
Rental income in prior year tax	Exclude rental income taxed at 15% final WHT from PT basis
Overpayment treatment	Credit against next year (not automatic refund)

Section 2 -- Required inputs and refusal catalogue

Required inputs

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.

Recommended -- current year of assessment, any PAYE or withholding tax deducted at source in the current year, the client's TIN.

Ideal -- full TA24 from the prior year, any CFR PT notice received, bank statements showing prior PT payments, any correspondence about PT reductions.

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.

Refusal catalogue

• 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." (Section 2 -- Refusal catalogue)
• 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." (Section 2 -- Refusal catalogue)
• 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." (Section 2 -- Refusal catalogue)

Section 3 -- Payment pattern library

This 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.

Section 4 -- Worked examples

Example 1 -- Standard three-instalment computation

Standard three-instalment computation

Instalment	Percentage	Amount	Due date
1st	20%	EUR 1,800	30 April 2025
2nd	30%	EUR 2,700	31 August 2025
3rd	50%	EUR 4,500	21 December 2025
Total	100%	EUR 9,000

Example 2 -- Reconciliation with final assessment (underpayment)

Input: Total PT paid = EUR 8,000. Final TA24 tax liability = EUR 11,500.

Output: Balance due = EUR 11,500 - EUR 8,000 = EUR 3,500. Due with TA24 filing by 30 June following the year of assessment.

Example 3 -- Reconciliation with final assessment (overpayment)

Input: Total PT paid = EUR 10,000. Final TA24 tax liability = EUR 7,200.

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.

Example 4 -- Rental income excluded from PT basis

Rental income excluded from PT basis

Instalment	Amount
1st (20%)	EUR 600
2nd (30%)	EUR 900
3rd (50%)	EUR 1,500

Example 5 -- Late payment penalty

Input: 1st instalment of EUR 1,800 due 30 April. Paid 15 July (2.5 months late).

Computation: Interest = EUR 1,800 x 0.75% x 3 months (rounded up) = EUR 40.50. Additional 10% penalty may apply at CFR discretion.

Example 6 -- Bank statement classification

Input line: 30.04.2025 ; CFR ONLINE PAYMENT ; DEBIT ; PT2025 INST 1 ; -1,800.00 ; EUR

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.

Section 5 -- Computation rules

5.1 Standard computation (prior-year basis)

• Standard computation (prior-year basis) — The computation basis is always the prior year assessed tax liability from the most recent TA24, after credits, minus any tax deducted at source. prior_year_tax = TA24_assessed_tax - tax_credits - WHT_at_source PT_instalment_1 = prior_year_tax x 20% PT_instalment_2 = prior_year_tax x 30% PT_instalment_3 = prior_year_tax x 50% total_PT = prior_year_tax x 100% Do NOT divide by three equally. The split is always 20/30/50. (Section 5.1)

5.2 Year-end reconciliation

• Year-end reconciliation — balance_due = final_tax_liability - total_PT_paid - WHT_at_source if balance_due > 0: additional payment required with TA24 (by 30 June) if balance_due < 0: overpayment -- refund or credit (Section 5.2)

5.3 Special rules for first year and new businesses

• Special rules for first year and new businesses — For 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. (Section 5.3)

5.4 Excluded income

• Excluded income — Income 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. (Section 5.4)

Section 6 -- Penalties and interest

6.1 Late payment interest

Late payment interest

Element	Rate
Interest rate	0.75% per month (9% per annum)
Runs from	Due date of each instalment
Maximum	No statutory cap -- accrues until paid
Additional penalty	CFR may impose 10% on amounts outstanding after final due date

6.2 Interest computation

• Interest computation — interest = unpaid_amount x 0.75% x months_overdue Interest accrues per instalment independently. A missed April instalment accrues 8+ months of interest by December. (Section 6.2)

Section 7 -- Adjustments and reductions

• Adjustments and reductions — If 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. Risk: if actual tax exceeds the reduced PT, interest and penalties apply on the shortfall. Flag for reviewer before advising any PT reduction. (Section 7)

Section 8 -- Edge cases

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.

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.

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.

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.

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.

EC6 -- Client ceases self-employment mid-year. Apply to CFR to cancel remaining PT instalments. Final TA24 reconciles actual liability.

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.

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.

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.

Section 9 -- Self-checks

Before delivering output, verify:

• Prior year TA24 tax liability confirmed (or CFR PT notice obtained)
• 20/30/50 split applied (NOT equal thirds)
• Rental income at final WHT excluded from PT basis
• All three instalment due dates stated (30 Apr, 31 Aug, 21 Dec)
• Year-end reconciliation formula presented
• First-year / new business rule checked
• Any adjustment request flagged for reviewer
• Overpayment treatment explained (credit vs refund)
• Penalty rates stated if relevant
• Output labelled as estimated until CFR notice confirmed

Section 10 -- Test suite

Test 1 -- Standard three-instalment computation

Input: Prior year TA24 tax liability = EUR 9,000. Expected: 1st = EUR 1,800 (30 Apr). 2nd = EUR 2,700 (31 Aug). 3rd = EUR 4,500 (21 Dec). Total = EUR 9,000.

Test 2 -- Zero prior year tax

Input: Prior year TA24 tax liability = EUR 0. Expected: PT = EUR 0. No instalments due. Flag: advise voluntary payments if current year income expected to exceed threshold.

Test 3 -- Underpayment reconciliation

Input: Total PT paid = EUR 8,000. Final TA24 = EUR 11,500. Expected: Balance due = EUR 3,500. Due with TA24 filing by 30 June.

Test 4 -- Overpayment reconciliation

Input: Total PT paid = EUR 10,000. Final TA24 = EUR 7,200. Expected: Overpayment = EUR 2,800. Client may request refund or credit.

Test 5 -- Late payment penalty

Input: 1st instalment EUR 1,800 due 30 April. Paid 15 July (approx. 3 months late). Expected: Interest = EUR 1,800 x 0.75% x 3 = EUR 40.50. Additional 10% penalty may apply.

Test 6 -- First year, no prior assessment

Input: First year of self-employment. No prior TA24. Expected: Flag for reviewer. Minimum PT per CFR administrative determination. Request CFR notice.

Test 7 -- Rental income excluded

Input: Prior year: EUR 3,000 tax on SE income + EUR 1,500 on rental (15% WHT). Total = EUR 4,500. Expected: PT on EUR 3,000 only. 1st = EUR 600, 2nd = EUR 900, 3rd = EUR 1,500.

Prohibitions

• NEVER compute PT without the prior year TA24 tax liability or a CFR PT notice
• NEVER use current year estimated income as the basis -- PT is always prior year
• NEVER advise skipping PT payments because income is expected to drop -- must apply to CFR
• NEVER divide by three equally -- the split is always 20/30/50
• NEVER include income subject to final WHT (rental at 15%) in the PT basis
• NEVER present PT figures as definitive without a CFR notice -- label as estimated
• NEVER advise on PT penalty disputes without escalating to a warranted accountant
• NEVER assume overpayment is automatically refunded -- client must apply or accept credit
