Frequently Asked Questions.

Not necessarily. Even with the same gross salary, your net income can change significantly depending on local tax rates, mandatory social security, healthcare contributions, and employer obligations.

Social security contributions vary by country and can materially affect your take-home pay. In some countries contributions are relatively low, while in others they can be substantial for both employees and employers.

Because income tax is only part of the picture. Social security, healthcare contributions, payroll taxes, pension deductions, and local mandatory charges can all reduce take-home income.

Double taxation means the same income may be taxable in more than one jurisdiction because of residency rules, income sourcing, or timing. It's rare although possible to pay in both jurisdictions however usually there are tax treaties available to reduce the amount.

No. A double tax treaty helps determine which country has taxing rights and whether tax paid in one country can be credited against tax due in another.

It does not necessarily mean you will not owe additional tax.

If the country where tax is ultimately due has a higher tax rate than the credit available from the first country, you may still need to pay the difference.

The outcome depends on the countries involved, the type of income, treaty rules, and how foreign tax credits are applied.

Yes. A move to a higher-tax jurisdiction, changes in social security obligations, or differences in how income is taxed can increase your overall burden.

Highlighting this variation is one of the tools you will find in our platform. They are designed to project these adjustments instantly, allowing you to weigh the financial realities of your relocation.

Yes. Comparing gross salary alone rarely tells the full story. A proper comparison should include income tax, social security, healthcare contributions, employer costs, and treaty considerations.

That depends on net income, tax exposure, housing costs, benefits, social security, and long-term financial implications. Gross salary alone is rarely enough.

Yes. When you change tax residency mid-year, both countries may have taxing rights over different portions of your income depending on the timing of your move, your residency status in each country, and applicable treaty rules.

Some countries apply split-year tax treatment, which can reduce the exposure, but this depends on the specific rules of the countries involved.

Yes. Remote work across borders can trigger personal tax residency changes, employer obligations, payroll exposure, and permanent establishment risk.

Earlier than most people think.

Decisions around where you live, where you incorporate, how you structure ownership, how you pay yourself, and where value is created can all materially affect your future tax position.

The tax consequences of dividends, equity ownership, social security, cross-border income, and eventual exits are often shaped by decisions made at the beginning, not later.

Planning before setting up the business can help avoid costly restructuring, unexpected tax exposure, and inefficient ownership structures down the line.

Long-term success requires looking far beyond tax brackets. While intelligent fiscal planning is critical, tax is ultimately just one factor, and in itself, it will never be the deciding factor for a sustainable move. A truly successful relocation balances financial efficiency with practical, everyday realities. Before transitioning, you must weigh the destination's legal framework, infrastructure, cultural alignment, and lifestyle.

tAIxable provides the cross-border clarity you need so you can align a smart tax setup with a destination that genuinely fits your life.

tAIxable acts as an intelligent computational layer for your firm, giving you rapid, structured access to cross-border tax logic across multiple jurisdictions. To guarantee professional-grade reliability, our engine is built strictly upon official statutory frameworks and published regulatory sources.

Furthermore, this data undergoes a rigorous dual-validation process, audited both by our internal specialist teams and vetted externally by our collaborative network of international tax partners. This ensures you can drastically reduce manual research time and draft client briefings faster, backed by accurate, peer-reviewed data.

Yes. Partner advisors can flag outdated rates, propose corrections, and submit updated data for admin review. Every proposed change is logged, attributed, and reviewed before going live — keeping the platform accurate and giving you a direct role in improving the data quality for your specialist markets.

The Partner Portal gives tax advisors a dedicated workspace to view country-level tax data, submit proposed edits, track the status of their submissions, and receive notifications when data in their markets is updated. It is separate from the individual user experience and designed specifically for professional advisory workflows.

tAIxable is built for both advisors and the individuals they serve. Your clients can use the platform independently to get an initial picture of their cross-border tax position — and then come to you for the expert layer on top. This is by design: better-informed clients make for more productive advisory conversations.

We welcome qualified tax professionals with demonstrable expertise in at least ONE Country. They are able to advise clients on tax advisory needs and have the vision to scale and grow their practice.

Global mobility goes far beyond HR or financial metrics, it is a strategic blueprint that impacts corporate growth and employees lives. A successful cross-border relocation requires full alignment between an employee's expectations and a company's regulatory compliance. Before any move, both sides need absolute clarity on tax, take-home pay, and social security obligations.

tAIxable serves as the collaborative framework where employers and teams map these scenarios together, ensuring every international transition is structured for mutual peace of mind and shared success.

tAIxable models both the origin and destination country simultaneously — mapping income tax rates, social security obligations, applicable treaties, and net take-home across the full employment picture. For mobility professionals, this means an immediate side-by-side view of what an assignment or relocation actually costs the employee and the employer.

The underlying tax information is mostly the same.

An international move affects employee take-home pay, employer costs, social security obligations, tax residency, and overall relocation economics. Both the employer and employee need visibility into that same information to make informed decisions.

Traditionally, this information is often reviewed separately by different providers, creating duplication, inconsistent assumptions, and unnecessary additional cost.

We believe both sides should be able to plan using the same information, in the same environment, before decisions are made.

Businesses routinely plan for tax before making major decisions, whether setting up a company, entering a new market, or moving talent internationally.

Individuals, despite being directly affected by those same decisions, have historically had far less access to the same planning visibility.

Yet a relocation can materially affect an employee's take-home pay, tax exposure of their personal investments, social security obligations, and long-term financial position, while also affecting employer costs and business decisions.

Collaboration matters because both sides are impacted, and better decisions happen when employers and employees can plan using the same information from the start.

Because global mobility planning has traditionally been fragmented and the market size wasn't historically big enough for a company to build the global technology to release it.

Tax is handled in one place, immigration in another, compensation elsewhere, and employee financial planning separately. Historically, businesses charge high prices and capitalise on these being separated.

But these decisions are fundamentally interconnected and doing it together can save a significant amount of costs for businesses and individuals.

We've changed that by creating a shared planning environment where employers and employees can evaluate the same tax and relocation implications together before decisions are made.

Before launching. Where you incorporate, how you structure the business, how you pay yourself, and where activity takes place can all affect the tax position of both the business and the individuals involved.

Tax planning at the setup stage helps avoid costly restructuring and unexpected obligations later.

Before making hiring decisions. The tax cost of hiring internationally can vary significantly between countries, affecting both the business and the individual.

Employer tax obligations, social security contributions, employee take-home pay, and the overall cost of engaging talent can differ materially depending on where the person is based and how the arrangement is structured.

Understanding those costs early allows businesses to compare countries, plan more effectively, and avoid unnecessary tax expense before committing to expansion.

Cross-border equity taxation is one of the most complex areas in global mobility. The tax treatment of stock options and restricted share units depends on the grant date, vesting schedule, exercise date, and the countries where the employee worked during each of those periods. tAIxable automates the planning for these scenarios.
