The Costs Founders Miss When Comparing Two Tax Regimes

Two countries can produce very different estimates for the same founder. The headline rate might favour one, but the calculations may begin with different definitions of taxable profit. One estimate includes the employer’s social contributions. The other assumes the owner withdraws the whole balance as dividends, with no professional fees or extra administration. Before drawing a conclusion, make sure both calculations describe the same business and the same household.

Begin with a year of ordinary trading. Choose a level of revenue, the costs of earning it and a realistic amount the company needs to keep. Decide what the founder actually does, where the work is performed and how the founder expects to be paid. Keep these facts the same across the comparison or name exactly which ones change. You need a comparison of business models as well as rates if a new location requires different premises, staff or pay.

Start with comparable profit

Record revenue and business expenses in the currency in which they occur. Separate operating costs from investment in assets and one-off setup costs. Ask the advisers which amounts can be deducted under each system, when they can be deducted and which company earns the revenue. If your business has more than one entity, identify intercompany transactions and costs that are shared. A smaller headline rate applied to a different taxable amount can give an unexpected result.

The UK corporation tax guidance illustrates how the applicable rate can depend on profit, the accounting period and associated companies. Make the same checks wherever you are comparing. A published rate may apply to a particular threshold, type of activity or time period. If a lower rate depends on a qualification, give it its own scenario. Compare the result if you meet the conditions with the result if the ordinary rate applies.

Track what reaches the founder

Build one line for salary, another for dividends and another for other expected payments. Ask for the company’s employer cost, what the company can lawfully distribute and what the founder expects to receive after personal taxes and contributions. If you will continue to receive income or own assets in another country, ask about separate tax exposure and treaty relief. Record the effective date of each conclusion and show the cash available in the month it can actually be used.

For an illustration, a comparison might show £12,000 more annual take-home in the destination before other costs. Assume you spend £3,000 more on accountancy and filing, £4,000 on travel back to customers and £2,000 on additional insurance. The estimated advantage falls to £3,000 before any changes to housing or conversion costs. If some costs are paid by the company and others by the founder, show them on the correct side and ask whether they affect taxable amounts. These figures illustrate the comparison, without assuming a tax result.

Add the costs that sit outside a tax rate

• Business administration. Price payroll, filings, accounting, local support, insurance and any entity or registered address. Identify costs that recur even when you have little revenue.
• Keeping the business working. Include extra travel, time-zone coverage, tools, local staff and any work you would need to replace. Show how the extra cost affects the company’s ability to serve customers.
• Household spending. Add rent, transport, healthcare and schooling where relevant. Compare the costs for an ordinary year after you have settled and for the first year with deposits and moving bills.
• Cross-border banking and timing. Use a realistic exchange assumption and include transaction costs. Separate amounts expected to arrive promptly from refunds or relief claims that could take longer.
• Future changes. Add a line for circumstances that would change the comparison, such as hiring, selling the business, moving again or giving up a relief.

Check which costs increase with revenue and which are fixed. A new company might have similar filing costs during a quiet year, while employer charges and staff costs vary. Model a lower-profit year alongside the expected year. If you need the household income to cover a fixed rent, compare the cash available after the company retains enough to pay its own bills. The average result over several years matters, but so does the year in which income is weakest.

Separate the move year from a steady year

Run the first year using actual months and dates. The founder may still work in both places, keep two homes for a period or pay for advice in both countries. There may be adjustments to payroll and filings in more than one tax year. Ask which facts affect residence and whether the move can create a tax or reporting event for the company, its owners or particular assets. Compare that year with a later year in which the business and household are operating as planned.

Think about an exit or a return while you build the comparison. A founder may move for a trial period, take on a local customer or decide to sell earlier than expected. Put those scenarios into the model if they are realistic. Ask the adviser whether the results depend on remaining resident for a period, meeting an ongoing requirement or obtaining relief from another authority. A condition with a meaningful effect belongs beside the number it changes.

Look at what stays in the company

Some comparisons assume that every pound of post-tax profit is paid to the founder. If you are building a company that needs working capital or investing in new products, that can be the wrong starting point. Decide how much cash the business will keep after expected tax, operating expenses and owner payments. Ask whether the destination changes what you must spend or where the cash must sit. Two choices can leave the same household income while giving the companies very different capacity to hire or invest.

Find the first year in which setup costs are recovered under each scenario. If one move has a smaller recurring cost but requires higher spending at the start, the difference may take time to appear. Include the effect of slower sales while you travel or get established. If you retain a fallback plan to return or change locations, estimate what it would cost to close down or maintain the arrangements you put in place.

Give the figures a date and write down which official rates or adviser estimates were used. Tax and operating assumptions can change at different times. A dated comparison lets you refresh the few figures that matter before making a commitment.

1. Write the baseline. Use the same revenue, business activity, work pattern and household goals for both calculations.
2. Request the underlying figures. Ask each adviser to show taxable profit, company tax, employer costs, personal receipts and any tax or relief they assume.
3. Add costs and dates. Put setup, travel, household spending and currency effects on a calendar. Compare cash during the transition and during ordinary operations.
4. Test the assumptions. Run a quieter year, a delayed move and a change in any condition that controls the largest amount. Record where you still need professional confirmation.

The resulting comparison should show what the company can retain, what the founder can use and when each amount is available. Keep the conditions with the figures. If a new quote, customer or work pattern changes the plan, you can then update the relevant line and see whether the difference still justifies the move.
