Before you start

A valid residence permit and Emirates ID
For a business: a trade licence plus corporate tax registration, regardless of the rate you expect to pay
For a Tax Residency Certificate: evidence supporting whichever of the three statutory routes you rely on
An understanding of your home country's rules, which do not stop applying because the UAE taxes nothing

Step-by-step

1
Confirm there is no income tax, federal or local
Salaries are untaxed federally, and Abu Dhabi emirate adds no personal income tax of its own. Unlike Dubai and Sharjah — which levy a municipality fee on residential rent, collected through the utility bill — you should ask specifically what municipality charge, if any, attaches to your Al Ain lease, because it is not always visible on a listing.

2
Budget 5% VAT into everyday prices
VAT applies at 5% to most goods and services nationwide and is generally included in the displayed price. Residential rent is broadly outside it. Consumers never file anything; only VAT-registered businesses do.

3
Register any business for corporate tax whatever rate you expect
Corporate tax applies at 9% on taxable profits above AED 375,000. Registration and filing are required regardless of whether tax is actually due, and failing to register is its own penalty. If you consult on the side while employed, get advice on whether you need a licence at all.

4
Understand gratuity instead of a pension
Expatriate employees accrue an end-of-service gratuity under the federal labour law, based on basic salary and length of service and paid when employment ends. It is deferred pay, not a pension, and because it is calculated on basic rather than total package, a heavily allowance-weighted offer quietly shrinks it.

Apply for a Tax Residency Certificate through whichever route fits
Cabinet Decision 85 of 2022 provides three alternative bases: 183 days or more of presence in the UAE in a twelve-month period; or 90 days plus a valid residence permit and a permanent home, job or business here; or having your usual place of residence and centre of financial and personal interests in the UAE. Applications go through the Federal Tax Authority's EmaraTax platform.

Documents you’ll need

Emirates ID and residence permit
Passport with entry and exit records for a day-count claim
Tawtheeq tenancy contract or title deed and utility bills as evidence of a permanent home
Employment contract or trade licence, depending on which limb you rely on
Bank statements covering the relevant period

Things most newcomers don’t know

The Tax Residency Certificate has three routes, and most guides mention one.

Everyone quotes 183 days. Cabinet Decision 85 of 2022 also allows 90 days in a twelve-month period combined with a valid residence permit and a permanent home, job or business here, and separately allows a claim based on usual residence plus a centre of financial and personal interests in the UAE. Someone who travels constantly for work may fail the day count and still qualify — and is exactly the person whose home country will demand the certificate.

Negotiate the basic-salary split, because it is your gratuity.

End-of-service gratuity is calculated on basic salary, not total package. Two offers with identical headline numbers can differ substantially in what you walk away with after five years, purely on how much is called 'basic' and how much is called housing or transport allowance. It is one of the few genuinely negotiable levers in a Gulf offer and almost nobody raises it.

Ask what municipality fee rides on your rent, rather than assuming there is none.

Dubai bills a 5% housing fee through the DEWA account and Sharjah levies a fee of roughly 4% collected through SEWA. Abu Dhabi emirate handles this differently again, and the figure is rarely on the listing. Getting it in writing before you sign turns a recurring surprise into a number you budgeted for.

Zero UAE tax does not mean zero tax on you.

Your home country's rules keep running. US citizens file regardless of residence. Many other countries tax you until you have genuinely severed residence, and some levy exit or deemed-disposal charges on departure. The UAE's zero rate is something you secure by leaving the other system properly, not something that arrives with your Emirates ID.

Common mistakes to avoid

Believing the Tax Residency Certificate requires 183 days when two other statutory routes exist.
Accepting an offer with a small basic salary and large allowances without pricing the gratuity effect.
Failing to register a side business for corporate tax because you expect the rate to be zero.
Assuming zero UAE income tax removes your home-country filing obligations.
Budgeting rent without asking what municipality charge attaches to it.
