For Employers

End-to-end tax for your business and your employees.

Direct tax compliance for your business — equity, payroll registration, permanent establishment, and relocation. Plus filing and advisory for your employees, offered as a benefit.

The gap

Two problems
that compound each other.

01

Your problem

Every salary, bonus, equity vest, and option exercise paid abroad triggers tax — equity comp reporting to HMRC, Permanent Establishment risk in the Netherlands, social security in Spain. Big 4 fees today: $3,000–8,000 per employee per year.

02

Their problem

Your international employees face US expat filing, treaty elections, equity exercise planning, and FBAR/FATCA — with nowhere to turn. Deel handles payroll. Sphere handles sales tax. Nobody handles the direct tax triggered by your people.

03

Agentax solves both

You manage compliance. Your employees get expert tax support as a benefit. One platform, data flowing both ways.

For your company

Five ways your people trigger tax.

Everything we do is driven by where your employees are. Each pillar opens with why the tax is owed — then what we do about it.

Equity Compensation

Why tax is owed: every RSU vest, NSO/ISO exercise, and ESPP purchase is a taxable event in the country where the employee works. We handle cross-border sourcing, employer reporting (HMRC share schemes, Dutch Box 1), withholding, and AMT modeling.

Payroll Registration

Why tax is owed: employing someone in a country registers you as an employer there, with ongoing withholding and filing obligations. We handle local registration, social security coordination, totalization elections, and annual employer returns.

Permanent Establishment Risk

Why tax is owed: your employees' work abroad can make your company taxable on profits in their country — even without a subsidiary. We assess exposure by country using OECD safe harbor rules, monitor thresholds, and advise on structuring.

Relocation Compliance

Why tax is owed: when an employee moves, their residency, your withholding, and both sides' filing obligations all change. We handle split-year filing, treaty tie-breakers, state departure, and new-country employer setup.

Employee Tax Support

Why tax is owed: your international employees owe US income tax on what you pay them — navigating FEIE, FTC, treaty elections, and FBAR is on them. We file their return, write advisory memos, and handle equity planning — offered as a benefit.

For your employees

Tax compliance as a benefit.

You pay per employee per year. They get filing, advisory memos, equity exercise planning, and FBAR/FATCA handled at no cost to them — a benefit your international team actually needs.

US expat tax filing

Complete return preparation — 1040, FEIE/FTC optimization, equity comp reporting, FBAR/FATCA. AI-powered with licensed professional review. From $250 per employee.

Equity exercise planning

Before your employees exercise options or sell RSUs, they get jurisdiction-specific guidance on tax impact, optimal timing, AMT exposure, and treaty relief.

Cross-border advisory memos

Situation-specific analysis with authoritative citations. Treaty optimization, relocation tax impact, foreign pension treatment, and compliance obligations.

Compliance filing

Extension filing, FBAR, FATCA, treaty disclosures — deadlines tracked and obligations flagged proactively so your employees never miss a filing.

When your team needs Agentax.

RSU vesting across borders

Employees vest US RSUs while working in London or Amsterdam. You need to know the withholding obligations in each jurisdiction. They need to understand their personal tax exposure.

Stock option exercises

An employee exercises ISOs from abroad. Your company has employer reporting obligations to HMRC or the local tax authority. The employee needs to model AMT and local tax treatment.

Employee relocation

An employee moves from NYC to London mid-year. You need to handle payroll registration, social security coordination, and potential Permanent Establishment implications. They need split-year filing and FEIE planning.

Permanent Establishment risk from senior hires

Your VP of Sales is based in Amsterdam and signs contracts on behalf of the company. This may create a permanent establishment in the Netherlands — triggering Dutch corporate tax obligations.

Annual share scheme filings

HMRC requires annual share scheme returns for all UK employees with equity. Missing the deadline means penalties. We track the filing calendar across every jurisdiction.

Annual employee tax filing

Tax season arrives and your international employees need more than a domestic return — FEIE, FTC, treaty elections, foreign reporting requirements. We handle it as part of their benefit.

How it works.

We map your workforce

We understand your employee locations, equity structures, and employer obligations across jurisdictions. We assess your current compliance posture and identify gaps.

Your compliance is managed

Equity comp reporting, Permanent Establishment risk monitoring, and employer filing obligations are tracked on the platform. You get alerts when something needs action.
