Tax advisor interview questions, with worked answers

How to use these questions

Practise each short answer aloud, then add a case from your own work: the client type, the question, what you found and what it changed. Many tax interviews include a short written case, such as a VAT question on an invoice or a computation from a trial balance, so practise working on paper as well as talking.

Corporate income tax and VAT

How is the profit of a German GmbH taxed, and how does that compare with a US or UK company?

What they check: that you know the profit taxes of your country by name and can place them next to other countries.

Short answer: "A German GmbH pays Körperschaftsteuer, the German corporate income tax, at 15 percent plus a solidarity surcharge on top, and Gewerbesteuer, the German trade tax, which each town sets through its own multiplier. Together that is often about 30 percent of profit in Germany. A US company pays federal corporate income tax at 21 percent on Form 1120, plus state tax in most US states. A UK company pays corporation tax to HMRC at a main rate of 25 percent in the UK, with a lower rate for small profits."

The full answer: The taxable profit starts from the accounts and is then adjusted: some costs are not deductible, some income is exempt, and losses from earlier years can be offset within limits. In Germany, the trade tax adds back part of the interest and rent, so two companies with the same profit can pay different trade tax; a German law of 2025 lowers the corporate rate step by step from 2028. In the US, the state taxes differ a lot, so a group plans where its profits fall. In the UK, large companies pay in quarterly instalments. Say the year of each rate you quote, because rates move.

A weak answer: "Companies pay about a third of their profit everywhere." Follow-up: "The client made a loss this year." Explain the loss carry-forward of the country and its limits, and in Germany the one-year carry-back.

A client in Germany sells consulting services to a business customer in France. Which VAT rules apply?

What they check: the place of supply and the reverse charge, the VAT basics that trip people up most.

Short answer: "Under the EU VAT Directive, a service to a business customer is taxed where the customer is, so the place of supply is France. The German seller charges no German Umsatzsteuer; the invoice names the French customer's VAT number and says the reverse charge applies, and the French customer accounts for French VAT. The German seller reports the sale in its German VAT return and in the EU recapitulative statement."

The full answer: VAT is a tax on consumption: each business charges it on sales and deducts the VAT it paid on purchases, so only the final consumer bears it. The EU rules, set by the EU VAT Directive and each member state's law, decide where a supply is taxed. For goods sent to a business in another EU country, the sale is usually exempt in the seller's country and taxed as an intra-EU acquisition by the buyer. Check the customer's VAT number in the EU's VIES system before invoicing. Outside the EU, the UK has its own VAT since leaving, Switzerland has its MWST at a standard rate of 8.1 percent in Switzerland, India has GST, and the US has no VAT at all, only sales taxes set by each US state.

A weak answer: "We add German VAT to every invoice to be safe." That gives the customer a VAT they cannot deduct and the seller a tax it did not owe. Follow-up: "The customer is a private person." Then the general rule is the seller's country, with special rules for some services and for sales online to consumers in the EU.

Transfer pricing

What is transfer pricing, and how do you show a price between group companies is at arm's length?

What they check: that you understand why tax offices care about prices inside a group, and the methods used to test them.

Short answer: "Transfer pricing is the setting of prices for goods, services, loans and rights between companies of the same group. Tax offices want each company to earn what an independent company would earn for the same work and risk: the arm's length principle of the OECD Transfer Pricing Guidelines. I show it by comparing with prices or margins of independent companies, using the method that fits the transaction."

The full answer: First, describe the transaction: who does what, who owns the assets and who bears the risks. Then pick a method from the OECD Guidelines: the comparable uncontrolled price where real market prices exist, cost plus for routine services or contract manufacturing, the transactional net margin method, which compares a company's profit margin with independent companies, and the profit split for highly integrated businesses. Compare with data from a database of independent companies and set a range. Most countries follow the OECD rules in their own law, such as Section 482 of the US tax code and the German Foreign Tax Act.

A weak answer: "We charge cost plus 5 percent because everyone does." A rate needs evidence for this transaction. Follow-up: "The distributor made losses three years in a row." A routine distributor rarely makes lasting losses at arm's length; check the functions and whether a year-end adjustment is needed.

Which transfer pricing documents must a group keep, and when?

What they check: that you know the three tiers of documentation and the national deadlines.

Short answer: "Under the OECD's rules, a master file describes the whole group, a local file in each country describes that company's transactions with its prices, and groups with revenue of 750 million euros or more file a country-by-country report showing profit, tax and staff per country. Each country sets its own deadlines and thresholds, so I keep them in the filing calendar."

The full answer: Germany asks for the documents within 30 days of a request in a German tax audit, and for unusual transactions a record made at the time. India asks for an accountant's report on the transactions, Form 3CEB in India, by its own due date. The US expects the documents to exist when the US return is filed, to avoid penalties. Keep the files up to date every year rather than writing them in a hurry when an auditor asks; a file written at the time is far more convincing.

A weak answer: "We write the documents when the tax office asks for them." Follow-up: "The group sells a brand from one country to another." That moves value; it needs a valuation and, in some countries, an exit tax check.

Compliance and filing calendars

How do you build a filing calendar for a group with companies in several countries?

What they check: that you run compliance as a system, with owners and reminders, not from memory.

Short answer: "I list every company, every tax and every return with its legal deadline, the payment date and who prepares, reviews and submits it. I work back from each deadline to the date the figures must be ready. The calendar sits in one shared place, with reminders, and I review it each month and whenever a rule changes."

The full answer: A calendar covers the yearly returns, the monthly or quarterly VAT returns, advance payments, withholding taxes and the transfer pricing files. Deadlines differ a lot: German VAT returns are due by the tenth of the next month, with a one-month extension on request in Germany; a UK company files its corporation tax return within twelve months of its year-end in the UK but pays earlier; a US company's federal return is due in the fourth month after year-end in the US, with an extension available. Add holidays, the dates of the local accountants, and a check that each return was really received.

A weak answer: "I keep the dates in my head; there are not that many." Follow-up: "Who checks the person who keeps the calendar?" A second reviewer and a monthly report to the tax manager of what was filed and what is open.

The figures for a return will be late and the deadline is in three days. What do you do?

What they check: judgement under pressure: the options of the law, and honesty with the client.

Short answer: "I first check whether an extension is possible and ask for it in writing before the deadline. If not, I file the best return I can with the figures available, mark the estimates, and correct it when the final figures arrive. I tell the client the risk and cost of each option the same day."

The full answer: Late filing costs money in most countries: Germany charges a late filing surcharge on a German return, HMRC charges penalties that grow with the delay in the UK, and the IRS charges a penalty for each month in the US. An estimate filed on time and then corrected is often better than nothing, but it must be an honest estimate. Afterwards, find out why the figures were late and move the internal date earlier next year.

A weak answer: "I would file whatever we have and hope nobody notices." Follow-up: "The client asks you to file a figure you know is wrong." Refuse, explain why, and write the conversation down.

Deferred tax

Explain deferred tax to a manager who is not from finance.

What they check: that you understand deferred tax well enough to explain it simply.

Short answer: "The accounts and the tax return sometimes count the same item in different years. A machine may be written off faster for tax than in the accounts, for example. That timing gap is a temporary difference: the tax is not saved, only moved to a later year. Deferred tax shows that future tax in the accounts today, so the tax charge matches the profit shown."

The full answer: A temporary difference is the gap between the book value of an asset or debt and its value for tax. If tax will be higher later, the company books a deferred tax liability; if tax will be lower later, for example because of losses it can still use, it may book a deferred tax asset. The rules are IAS 12 under IFRS, ASC 740 under US GAAP, and for German accounts under the German commercial code, where small companies may leave deferred tax out. Use the tax rate that will apply when the difference reverses, so a law that changes future rates changes the deferred tax today.

A weak answer: "Deferred tax is tax we have not paid yet." That is a tax debt, not deferred tax. Follow-up: "Why did our tax rate in the accounts jump this year?" Look for a change of tax rates, a loss that may not be used, or costs that are never deductible.

When may a company show a deferred tax asset for its tax losses?

What they check: the judgement behind a deferred tax asset, which auditors challenge most.

Short answer: "Only when it is probable that the company will make enough taxable profit to use the losses before they expire. I look at the profit plan, the history of losses, any limits on using them in the country, and whether there are deferred tax liabilities that will reverse in the same period."

The full answer: A company with a long run of losses needs strong evidence, such as signed contracts, before it can show the asset. The national rules matter: in Germany only part of the profit above a threshold may be offset by old losses in one year, so the asset is smaller than the losses times the rate. Write the reasons down, because the auditor will ask, and look at the plan again each year.

A weak answer: "The managers say next year will be good, so we book it." Follow-up: "The company is sold to a new owner." A change of owner can cut old losses under some national rules, such as in Germany and the US; check before the deal is signed.

Permanent establishments, tax treaties and the minimum tax

A German company lets a sales manager work from home in Spain. Does that create a permanent establishment?

What they check: that you know when a company becomes taxable in another country, a risk that has grown with working from home.

Short answer: "It can. Under the OECD Model Tax Convention, a permanent establishment is a fixed place of business through which a company carries on its business, or a person who habitually concludes contracts for it. If the manager works from that home office regularly and signs or negotiates contracts, Spain may tax the profit linked to that work. I would check the treaty between Germany and Spain and the facts."

The full answer: The test looks at the place, the time and the activity. A home office used now and then, or only for support work such as preparing documents, is often not enough. Regular sales work that ends in contracts usually is, because of the rule on dependent agents. The consequences are a tax return in the other country, profit to attribute there, and payroll duties for the employee. A policy for working abroad, with limits on the days and on what staff may sign, prevents most of the risk.

A weak answer: "No, the company has no office there." Follow-up: "The group has a warehouse in Poland." A place used only for storage is often an exception in the treaties, but check whether it is more than that.

How does a double tax treaty stop the same income being taxed twice?

What they check: that you can read a treaty and use it for a real flow of money.

Short answer: "A double tax treaty between two countries decides which of them may tax each kind of income, and how much. For dividends, interest and royalties it often lowers the withholding tax of the source country. The country of residence then either exempts the income or gives a credit for the tax paid abroad."

The full answer: Most treaties follow the OECD Model Tax Convention, so the articles have similar numbers: business profits, dividends, interest, royalties and the article on avoiding double tax. To use the lower rate, the company usually shows that it lives in the other country with a residence form from its tax office, and some countries add anti-abuse tests, such as the German rules on foreign holding companies. Under the multilateral instrument of the OECD, many treaties now also have a principal purpose test against treaty shopping.

A weak answer: "The treaty means you only pay tax in one country." Often both countries tax, with a credit. Follow-up: "The withholding tax was taken at the full rate." Claim the difference back from the source country within its deadline.

What does Pillar Two, the global minimum tax, mean for a group?

What they check: that a candidate for a group tax role knows the biggest change in international tax in years.

Short answer: "Pillar Two is the OECD's global minimum tax: groups with revenue of 750 million euros or more must pay at least 15 percent tax on their profit in each country. Where the effective rate in a country is lower, a top-up tax is due. In the EU it is law through the EU Minimum Tax Directive, in Germany through the German minimum tax act, and the UK has its own version."

The full answer: The work is mostly data: the profit and the covered taxes of every company, country by country, from the group accounts, with many adjustments. Simplified tests, the safe harbours, spare a group the full computation in countries with a clearly high rate. New returns are needed, with long first deadlines. Tax incentives that lower the rate below 15 percent lose value, so plans built on them need a second look.

A weak answer: "It only affects the very largest tech companies." Follow-up: "Where do we get the data?" From the consolidation system, with the finance team, mapped once and checked every year.

Tax software and data

How do you use DATEV or SAP in your tax work?

What they check: that you can get the tax data out of the systems, check it and file it.

Short answer: "In a German tax firm I work in DATEVAsked in 14% of tax advisor ads (as of 5 Nov 2026).The standard software of many tax firms and their clients: books, returns, payroll and the client portal.: the client's books, the annual accounts, the returns, and the transfer to the German tax office through ELSTER. In a large company the data sits in SAPAsked in 2% of tax advisor ads (as of 5 Nov 2026).Read tax codes, postings and reports in the ERP system of large clients and groups.: each posting carries a tax code, and the VAT return is built from those codes. Either way, I reconcile the return with the ledger in ExcelAsked in 10% of tax advisor ads (as of 5 Nov 2026).Tax computations, reconciliations of VAT to the ledger, and checks on large data exports. before it goes out."

The full answer: Most tax errors start with a wrong tax code or a missing invoice, not with the law. In SAP FISAP's finance modules: where the VAT codes, the tax accounts and the provisions for tax are kept., check the tax codes set up for each kind of purchase and sale, and run a data checkWork through large ledgers to find VAT errors, odd postings or transactions a tax audit will ask about. on large exports to find odd rates or missing VAT numbers. In Germany, the GoBD, the German rules for digital records, say how the data must be kept so a German tax auditor can read it. E-invoices are spreading too: German businesses must be able to receive them since 2025, and the duty to send them follows in stages.

A weak answer: "The software does the tax for us." Follow-up: "The VAT return does not match the ledger." Find the difference line by line: postings with the wrong code, posted after the cut-off, or entered by hand.

Tax audits

The German tax office announces a Betriebsprüfung, a tax audit. How do you prepare?

What they check: that you run a tax audit calmly, with facts, one point of contact and a plan.

Short answer: "A Betriebsprüfung is a tax audit by the German tax office. I read the audit order for the years and taxes it covers, agree the start date and a room, and name one person as the auditor's contact. I gather the returns, the accounts, the transfer pricing files and the data the auditor may ask to read, and look for the weak points myself before the auditor does."

The full answer: Under the German Abgabenordnung, the tax office may read the digital records itself, so check the data export first. Answer each question in writing, keep a list of what was handed over, and never guess: say when you will reply. Where a mistake comes to light, a voluntary correction before the auditor finds it is better than waiting. At the end, the auditor sends a report of findings; discuss each one in the closing meeting with the facts and the law. Other countries work the same way in principle, such as an HMRC enquiry in the UK or an IRS examination in the US.

A weak answer: "I would give the auditor everything and let them look." Follow-up: "The auditor proposes an adjustment you think is wrong." Argue it with the facts, offer a settlement on points that are unclear, and in Germany file an objection within one month of the assessment if you still disagree.

Advising clients

A client asks you to cut their tax bill with a scheme they read about online. How do you answer?

What they check: ethics and judgement: the line between planning and abuse.

Short answer: "I listen to what the client wants to reach, then check the scheme against the law and the anti-abuse rules. If it only works on paper, I say so plainly and explain the risk: back taxes, interest and penalties. Then I offer the lawful options that reach part of the goal, and confirm my advice in writing."

The full answer: Tax planning that uses the rules as intended is fine; arrangements whose main purpose is a tax advantage the law did not intend are not. In the EU, the DAC6 rules of the EU make advisors and taxpayers report certain cross-border arrangements to the tax office. Many countries have a general anti-abuse rule, such as the UK's general anti-abuse rule in the UK. Write down the facts the client gave you, your advice and the risks, because the advice is only as good as the facts behind it.

A weak answer: "If the client wants it, it is their risk." Follow-up: "The client insists." Decline that part of the work and confirm it in writing; your licence and your name are at stake.

How do you explain a difficult tax question to a client who is not a tax expert?

What they check: plain wordsAsked in 14% of tax advisor ads (as of 5 Nov 2026).Explain a tax rule, a risk or a deadline in plain words to a client who is no tax expert. and care for the clientAsked in 4% of tax advisor ads (as of 5 Nov 2026).Answer clients on time, keep them informed and treat their deadline as yours., the skills clients judge a tax advisor by.

Short answer: "I start with the answer and what the client must do, then the reason in one or two sentences, then the figures. I avoid section numbers in the talk, show the options side by side with what each costs, and send a short written summary afterwards with the next dates."

The full answer: A client cares about three things: how much, by when, and what could go wrong. Lead with those. Use an example from the client's own business rather than a rule. Say clearly what is certain and what is a judgement. If the client must decide, give your recommendation and why. Check at the end that the client can repeat the main point.

A weak answer: "I send them the text of the law." Follow-up: "The client is angry about a tax bill they did not expect." Listen first, explain where the bill comes from, and show what can still be done, such as an objection or a payment plan.

Senior tax consultant, tax manager, head of tax and tax partner

These questions come up for senior tax consultant, tax manager, head of tax and tax partner roles, where the work becomes review, risk and leading other people's work.

As tax manager or head of tax, how would you set up a tax control framework?

What they check: that you can run tax as a controlled process for a whole company, not as a set of returns.

Short answer: "I start with the risks: which taxes, which countries and which processes could go wrong. For each, a control: who checks what, when, and how it is recorded. Tax codes in the ERP system, a review of every return by a second person, the filing calendar and a log of open tax questions. I report the main risks to the CFO each quarter and test the controls once a year."

The full answer: In Germany, a documented tax control system helps show that an error in a German return was a mistake, not intent. In the UK, the senior accounting officer of a large UK company must confirm each year that the tax accounting is sound. Lead the tax teamLead a tax team: plan the work, review returns, train juniors and own the quality. so that reviews are real, not a signature. Keep a register of positions taken where the law is unclear, with the reasons, and the provision for each in the accounts.

A weak answer: "Our tax advisors handle all of that." Follow-up: "The board asks what our biggest tax risk is." Name it, give the amount at stake, the likelihood and what you are doing about it.
