Tax & Advisory Practice Lab
"The value of a tax computation tool is not in the arithmetic — it is in knowing which positions are arguable and what the consequences are if the authority challenges them."
In Lesson 11, you built workflows for accounting and financial reporting — bookkeeping, IFRS statements, month-end close automation, and consolidation. This practice lab shifts to the second CA/CPA domain: tax and non-assurance advisory. The exercises here are fundamentally different in character. Where accounting workflows follow standards that determine a single correct answer, tax and advisory workflows require you to make judgment calls about positions that are defensible but debatable.
These three exercises cover the full spectrum of Domain 2 practice: compliance (Exercise 12), transaction advisory (Exercise 13), and restructuring (Exercise 14). Each builds a complete Cowork workflow. Choose one or two to complete fully; review all three to understand the breadth of advisory workflows available to you.
Choose your path. Select the exercise that matches your practice area:
- Exercise 12 (45 min) — Tax compliance. Builds a full corporate tax computation for Pakistan under ITO 2001. Best for practitioners with tax compliance experience.
- Exercise 13 (60 min) — Transaction advisory. Runs M&A financial due diligence with DCF and comparable company analysis. Best for corporate finance and advisory practitioners.
- Exercise 14 (45 min) — Restructuring. Models three restructuring scenarios for a distressed company. Best for insolvency and advisory practitioners.
Data files: Use the entity profiles from the exercise zip: exercises/entity-profiles/crescent-textiles.md and exercises/entity-profiles/karachi-foods.md. Each exercise also provides hypothetical data inline.
Exercise 12: Corporate Tax Computation — Full Pakistan Jurisdiction Workflow (45 min)
What you'll build: A complete corporate income tax computation for a Pakistan-domiciled company under the Income Tax Ordinance 2001 and the Income Tax Rules 2002, producing a working paper ready for review and filing.
Requirements: Cowork, finance@knowledge-work-plugins, financial statements data (real or hypothetical below).
Hypothetical Entity
A private limited company in the manufacturing sector. Key data:
- Accounting profit before tax: PKR 18,500,000
- Corporate tax rate: 29%
- Depreciation charged: PKR 4,200,000 (tax depreciation on the same assets: PKR 5,100,000)
- Entertainment expense: PKR 850,000 (partially disallowable)
- Donation: PKR 200,000 to an approved charitable institution
- Brought-forward tax losses: PKR 2,400,000
- Dividend income: PKR 600,000 from a Pakistan-listed company (subject to final tax)
Step-by-Step Instructions
1. Accounting to taxable income bridge. Say:
I am computing corporate income tax for a Pakistani private limited
manufacturing company. Accounting profit before tax is PKR 18,500,000.
Work through the standard Pakistan income tax computation framework:
start with accounting profit, add back accounting depreciation
(PKR 4,200,000), deduct tax depreciation (PKR 5,100,000), identify
the entertainment expense disallowance, handle the donation deduction,
and exclude the dividend income that is subject to final tax. Show
each adjustment on a separate line with the applicable provision
of the Income Tax Ordinance 2001.
2. Apply the entertainment expense disallowance. Ask:
Under Section 21(l) of the Income Tax Ordinance 2001, entertainment
expenses are deductible only to the extent they satisfy the wholly
and exclusively for business test. Of the PKR 850,000 entertainment
expense, PKR 350,000 relates to a private dinner for the CEO's
family celebration. What is the disallowable amount and the
applicable provision? Add this to the tax computation.
3. Handle the brought-forward losses. Ask:
The company has brought-forward tax losses of PKR 2,400,000. Under
Section 56 and 57 of the Income Tax Ordinance 2001, confirm:
(a) what is the maximum period for loss carry-forward for a
manufacturing company?
(b) Are there any restrictions on set-off against current year
taxable income?
(c) Apply the set-off and show the residual losses carried forward.
4. Compute the tax liability. Ask:
Compute the tax liability at 29% on the adjusted taxable income.
Show: (a) Tax on taxable income, (b) Final tax on dividends
(assume 15% final tax on PKR 600,000 dividend income, already
withheld at source), (c) Total tax liability, (d) Any minimum tax
implications under Section 113 of the ITO — confirm whether regular
tax exceeds minimum tax.
5. Identify advance tax and withholding credits. Ask:
The company has paid advance tax of PKR 2,800,000 during the year
under Section 147, and has withholding tax credits of PKR 1,450,000
from customer receipts. Compute the net tax payable or refundable.
Show the balance of tax to pay with the due date for the annual
return under Pakistan tax law.
6. Identify disclosure obligations. Ask:
Are there any positions in this tax computation that require a
disclosure in the annual return — either because they represent
an aggressive interpretation of the law, or because a specific
schedule or annexure must be filed? List each disclosure obligation
with the relevant schedule reference.
7. Produce the formal computation. Ask:
Format the complete tax computation as a formal working paper at
/outputs/tax-computation.xlsx with: (1) Accounting profit per
audited accounts, (2) Adjustments for tax purposes (each on a
separate line with ITO section reference), (3) Adjusted taxable
income, (4) Tax computation, (5) Credits and payments,
(6) Net tax payable/refundable, (7) Brought-forward loss schedule.
8. Write the jurisdiction SKILL.md. Ask:
Draft the core instructions for a Pakistan corporate tax computation
SKILL.md. Cover: the six most common add-back items, the Section 113
minimum tax check, the final tax items that must be excluded from
regular tax, and the conditions that require escalation to a senior
tax professional.
Check your work: Step 6 is the most professionally important step. Identifying positions that are arguable — and that a tax authority might challenge — is the judgment that no tax computation tool can make autonomously. Your SKILL.md should encode your firm's risk appetite on arguable positions, not just the mechanical computation rules.
Pakistan (ITO 2001): This exercise uses Pakistan's Income Tax Ordinance 2001 as the worked example — the jurisdiction-specific provisions (Section 21(l) entertainment, Section 56-57 loss carry-forward, Section 113 minimum tax) illustrate the pattern. US (IRC / Form 1120): The same workflow applies with IRC provisions — Section 162 (trade or business expenses), Section 274 (entertainment), Section 172 (NOL carry-forward). The computation structure (accounting profit, add-backs, deductions, tax liability, credits) is universal. UK (CTA 2009 / CT600): UK corporate tax computation follows the same bridge from accounting to taxable profit. Key differences: capital allowances replace tax depreciation, and the corporation tax rate and payment dates differ.
Exercise 13: M&A Financial Due Diligence with Plugin Commands (60 min)
What you'll build: A financial due diligence process for a hypothetical acquisition, using /dcf and /comps commands to value the target and a structured framework to identify financial risks and adjustments.
Requirements: Cowork (Team or Enterprise), financial-analysis@financial-services-plugins and finance@knowledge-work-plugins installed, hypothetical target company financials (below).
Target Company Profile
Use this context in every step: A Pakistan-based FMCG company, three years of audited financial history.
| Metric | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| Revenue (PKR M) | 450 | 490 | 540 |
| EBITDA (PKR M) | 58 | 67 | 82 |
Net debt: PKR 35M. Management projects PKR 620M revenue and PKR 105M EBITDA in Year 4. Acquisition price being discussed: PKR 650M.
Step-by-Step Instructions
1. Quality of earnings assessment. Say:
I am performing financial due diligence on a Pakistan FMCG target.
Three years of financials are provided. Perform a quality of earnings
analysis: (a) Calculate revenue CAGR and EBITDA CAGR;
(b) Identify the EBITDA margin expansion from Year 1 to Year 3 and
explain what could drive this; (c) List five questions a due diligence
team should ask management to verify whether the EBITDA improvement
is sustainable or whether it includes one-off items.
2. Normalise EBITDA. Say:
Management claims reported EBITDA includes the following items that
should be added back for normalised EBITDA: (a) PKR 8M one-off legal
settlement in Y2; (b) PKR 4M above-market owner salary in all three
years (market rate PKR 2M); (c) PKR 6M in pre-acquisition professional
fees in Y3. Compute normalised EBITDA for each year after these
adjustments. Calculate the multiple the asking price of PKR 650M
implies on both reported and normalised Y3 EBITDA.
3. Run the DCF valuation.
/dcf target-company
When prompted for inputs, provide: Revenue Y4E PKR 620M, EBITDA margin 16.9% (PKR 105M), CAPEX 3% of revenue, tax rate 29%, terminal growth rate 4%, WACC 14% (reflecting Pakistan risk premium). Ask:
At what revenue growth rate does the DCF valuation equal the PKR 650M
asking price? What EBITDA margin assumption is embedded in that
growth scenario?
4. Run comparable company analysis.
/comps fmcg-pakistan
Ask:
Based on comparable FMCG companies in Pakistan and comparable emerging
market FMCG businesses, what EV/EBITDA multiple range would you apply?
How does the PKR 650M asking price compare on normalised Y3 EBITDA
of PKR 84M?
5. Working capital and cash analysis. Say:
Perform a working capital analysis. The target's debtor days have
moved from 42 to 67 days over three years, and inventory days from
38 to 52 days. Creditor days have remained stable at 45 days.
Calculate the cash conversion cycle at each year-end. Identify the
working capital investment required to support Y4 revenue. Adjust
the PKR 650M enterprise value for the normalised working capital
requirement.
6. Tax due diligence flags. Say:
Identify the five most common tax due diligence risk areas for a
Pakistan FMCG target. For each: what information should be reviewed?
What would constitute a red flag? What is the potential liability if
the risk materialises? Produce a tax due diligence checklist at
/working-papers/tax-dd-checklist.docx.
7. Produce the due diligence report. Say:
Produce a financial due diligence report at /outputs/dd-report.docx
with: (1) Executive summary — key findings and recommended price
adjustments; (2) Quality of earnings — normalised EBITDA bridge;
(3) Valuation — DCF and comparables; (4) Working capital — cash
conversion cycle trend and normalised requirement; (5) Tax — key
risk areas; (6) Key open items — questions to be answered before
closing. Maximum 8 pages.
8. Write the DD SKILL.md. Ask:
Draft a SKILL.md for a financial due diligence agent. Include: the
standard quality of earnings adjustments to always test, the working
capital normalisation methodology, the tax risk checklist items,
and the three findings that would always cause a deal recommendation
to be 'do not proceed'.
Check your work: The DCF and comps commands produce technically correct valuations. The professional judgment is in Steps 1, 2, and 5 — deciding which items to adjust out of EBITDA, what working capital is normal versus inflated, and how to interpret the cash conversion cycle trend. These are the findings that move the negotiated price. The agent cannot make these judgments without your instruction; but once you provide them, it can model their financial consequences quickly and completely.
Exercise 14: Restructuring Scenario Modelling (45 min)
What you'll build: Financial projections across three restructuring scenarios for a distressed company, with stakeholder recovery analysis and a professional recommendation.
Requirements: Cowork, financial-analysis@financial-services-plugins installed.
Distressed Entity Profile
A Pakistan manufacturing company in financial difficulty:
- Total debt: PKR 180M (PKR 80M bank, PKR 100M trade creditors)
- EBITDA: PKR 22M
- Annual interest cost: PKR 24M (company is loss-making after interest)
- Going concern doubt exists
Three scenarios under consideration:
- Consensual restructuring — banks accept 30% haircut, creditors accept 18-month payment terms
- Voluntary arrangement — formal creditor moratorium for 24 months, 40% haircut on unsecured creditors
- Asset sale — EBITDA-generating operations sold to a strategic buyer, remaining entity wound down
Step-by-Step Instructions
1. Current state analysis. Say:
Prepare a financial stress analysis. Current EBITDA is PKR 22M,
annual interest is PKR 24M. Calculate: interest coverage ratio,
net debt/EBITDA, and the cash shortfall per year if trading continues
with current debt structure. How many months of EBITDA is needed
to service debt at current levels?
2. Model Scenario 1: Consensual bank restructuring.
/lbo restructuring-scenario-1
Provide inputs: restructured debt of PKR 56M (PKR 80M x 70%), interest rate 12%, 5-year amortisation, EBITDA maintained at PKR 22M growing 5% annually, trade creditors on standard 18-month deferred terms.
Ask:
Show the debt service coverage ratio (DSCR) for each year of the
restructuring. At what EBITDA does the company breach a DSCR
covenant of 1.25x? What is the probability this restructuring
is sustainable?
3. Model Scenario 2: Formal voluntary arrangement. Say:
Under the voluntary arrangement scenario: unsecured trade creditors
(PKR 100M) receive 60 cents in the dollar (PKR 60M total payment
over 24 months). Bank debt remains at face value but is rescheduled.
Model the cash flows and show: (a) Total creditor recovery amounts;
(b) Cash required over 24 months; (c) Whether EBITDA is sufficient
to fund the arrangement without additional liquidity;
(d) The net present value of creditor recoveries at a 15% discount
rate.
4. Model Scenario 3: Asset sale and wind-down. Say:
An FMCG strategic buyer has indicated interest in the operating
assets at 5x EBITDA. Calculate the gross sale proceeds. Show the
application of proceeds in priority order: secured creditors first,
then unsecured. Produce a creditor waterfall showing recovery rates
for each class. Compare recovery rates across all three scenarios
in a summary table.
5. Stakeholder analysis. Say:
For each scenario, produce a stakeholder outcome table showing:
the bank's recovery (PKR and % of face value), trade creditors'
recovery (PKR and %), and equity holders' recovery (PKR and %).
Add a column for 'timeline to resolution' — estimated months from
today. Which scenario is best for each stakeholder class?
6. Professional judgment overlay. Ask:
What are the three factors that are most likely to cause Scenario 1
(consensual restructuring) to fail after it is agreed? What early
warning indicators should the monitoring CA/CPA watch for during
the restructuring period?
7. Produce the restructuring report. Say:
Produce a restructuring options report at
/outputs/restructuring-report.docx: (1) Executive summary —
recommendation; (2) Current financial position; (3) Scenario 1 —
analysis and creditor outcomes; (4) Scenario 2 — analysis and
creditor outcomes; (5) Scenario 3 — analysis and creditor outcomes;
(6) Comparative summary table; (7) Recommended course of action
with rationale.
Check your work: The modelling in Steps 2-4 takes hours manually and minutes with the /lbo command. The professional value-add is in Steps 6 and 7: identifying what causes restructurings to fail and making a recommendation. No model can make a restructuring recommendation without understanding the dynamics between creditors, the management team's credibility, and the operational viability of the business. The recommendation in Step 7 requires your judgment. The three scenarios in Steps 2-4 are what makes your judgment informed.
Pakistan: Restructuring in Pakistan follows the Companies Act 2017 (schemes of arrangement) and SECP regulations. The exercise structure applies regardless of jurisdiction. US (Chapter 11): The three-scenario framework maps directly — consensual out-of-court restructuring, Chapter 11 reorganisation, and Section 363 asset sale. Creditor waterfall priority (secured, unsecured, equity) follows the same logic. UK (Insolvency Act 1986): Company Voluntary Arrangement (CVA), administration, and pre-pack administration mirror the three scenarios. The Insolvency Practitioner's role is analogous to the monitoring CA/CPA in this exercise.
Try With AI
Use these prompts in Cowork or your preferred AI assistant to deepen your understanding of the tax and advisory workflows.
Prompt 1: Jurisdiction Translation
I completed the Pakistan corporate tax computation exercise using
the Income Tax Ordinance 2001. Now I need to understand how the
same computation works in [MY JURISDICTION — e.g., US, UK, UAE,
India, South Africa].
For each step in the Pakistan computation, identify:
1. The equivalent provision in my jurisdiction's tax law
2. Any step that does not have a direct equivalent (and why)
3. Any additional step my jurisdiction requires that Pakistan
does not
Produce a side-by-side comparison table showing:
Pakistan provision | My jurisdiction's equivalent | Key difference
What you are learning: Tax computation structure is remarkably consistent across jurisdictions — accounting profit, add-backs, deductions, loss relief, credits, minimum tax check. The specific provisions differ, but the workflow pattern transfers. By mapping your jurisdiction to the Pakistan worked example, you build a jurisdiction-specific mental model that makes every tax computation exercise in this chapter applicable to your practice.
Prompt 2: Due Diligence Red Flag Identification
I am reviewing a target company for acquisition. The following
financial trends have emerged from three years of data:
- Revenue growing at [X]% CAGR
- EBITDA margin expanding from [Y]% to [Z]%
- Debtor days increasing from [A] to [B] days
- Inventory days increasing from [C] to [D] days
For each trend, explain:
1. What could legitimately drive this trend (positive explanation)
2. What could artificially inflate these numbers (red flag)
3. What specific documents or data I should request to
distinguish between the two explanations
Then rank the trends from most to least concerning from a due
diligence perspective and explain your ranking.
What you are learning: Financial due diligence is fundamentally about distinguishing genuine business performance from artificial or unsustainable performance. Every positive financial trend has both a legitimate and an artificial explanation. The professional skill is in knowing which questions to ask to distinguish between them — and which documents would provide the answer.
Prompt 3: Restructuring Feasibility Assessment
A [DESCRIBE ENTITY — industry, size, geography] is in financial
difficulty. Current EBITDA is [X], total debt is [Y], and annual
interest cost is [Z].
Model three scenarios:
1. Consensual restructuring with [TERMS]
2. Formal insolvency process under [MY JURISDICTION'S LAW]
3. Asset sale to a strategic buyer at [MULTIPLE] x EBITDA
For each scenario, calculate:
- Creditor recovery rates by class (secured, unsecured, equity)
- Timeline to resolution
- Key risks that could cause the scenario to fail
Then recommend which scenario I should present to stakeholders
first and explain your reasoning — not just which is best
numerically, but which is most achievable given the likely
dynamics between the parties.
What you are learning: Restructuring recommendations are not determined by the numbers alone. The achievability of a scenario depends on creditor relationships, management credibility, and operational complexity — factors that no financial model captures. The model tells you what is possible; your judgment tells you what is achievable. This prompt forces you to articulate the difference.
