Oman's 5% income tax in 2028: the Gulf tax-free era ends
Royal Decree 56/2025 makes Oman the first Gulf state with a personal income tax, and high-billing independents have until 2028 to get their numbers in order.

For a long time, the deal for working in the Gulf read like one line. You earn, and you keep what you earn. No income tax, no annual personal return, nothing skimmed off the top. Oman has now drawn a line under that idea for its highest earners.
On 22 June 2025, Oman issued Royal Decree No. 56/2025, the Personal Income Tax Law. It puts a 5% tax on individuals whose annual income passes OMR 42,000, about USD 109,000, and it takes effect on 1 January 2028 (KPMG). That makes Oman the first member of the Gulf Cooperation Council to put a personal income tax on the books (EY).
If you are a consultant, a senior freelancer, or a studio owner billing well into six figures, read this one closely. Not because 5% will hurt. Because of what it signals about the next decade in the region.
What Royal Decree 56/2025 actually does
Strip away the headlines and the law is fairly narrow. It introduces a flat 5% rate on the taxable income of natural persons, and that rate only bites once your income clears OMR 42,000 a year (Oman Tax Authority). The text runs to 76 articles across 16 chapters, so there is plenty of detail underneath, but the core mechanic is one rate sitting above one threshold ().
The word that matters is taxable. You are not taxed on every riyal you bring in. The law works off net income, which is your gross income minus the exemptions, deductions, and losses the law allows (DLA Piper). Gross income itself is broad. It picks up salary, self-employment earnings, rental income from property, returns on shares and sukuk, and proceeds from selling real estate (EY).
Residency decides how far the tax reaches. A tax resident, broadly someone present in Oman for more than 183 days in a tax year, is taxed on income earned inside Oman and abroad. A non-resident is taxed only on income sourced in Oman (EY). For a freelancer who lives in Muscat and bills clients in Dubai, London, and Riyadh, that is not an academic distinction. Foreign earnings can count toward what you owe.
One nuance is worth flagging. The 5% is a flat rate, not a ladder of brackets. But because the first OMR 42,000 sits outside the tax, the share of your income that actually goes to tax still rises the more you earn above the line. Someone barely over the threshold pays almost nothing in effective terms. Someone well above it edges toward a full 5% of the excess. PwC frames the structure as progressive once deductions are accounted for, which is the same point put a different way (PwC).

Who is in scope: the OMR 42,000 line
Here is the reassuring part for most people, and the part high earners should not lean on. The Oman Tax Authority expects roughly 99% of the population to fall outside the tax entirely, with only about 1% earning enough to be liable (Oman Tax Authority). OMR 42,000 is a high bar in local terms. Most salaried residents will never reach it.
Six-figure freelancers and consultants are exactly the slice that does. If you bill USD 109,000 or more across a year, you are in the conversation (PwC). The thing to get right is what counts toward that line. It is annual income after the law's deductions, not your top-line invoiced revenue. The decree builds in allowances that reflect ordinary life in Oman, covering education, healthcare, inheritance, zakat, donations, and primary housing, among others (Oman Tax Authority). DLA Piper's read adds detail on the relief side, including an exemption window for some foreign-earned income and softer treatment for gains on a primary residence (DLA Piper).
So the test is not "did I invoice more than OMR 42,000." It is closer to "after eligible deductions, did my taxable income clear OMR 42,000." Two freelancers with the same gross can land on different sides of the line depending on what each can deduct. That is precisely why your records, and not your gut feel, should answer the question.
Why 2028 matters now, not in three years
January 2028 sounds far enough away to file under "later." It is not, for two reasons.
First, the rulebook is being written in the meantime. The decree was published in the Official Gazette on 30 June 2025, and the executive regulations, the part that fills in the practical detail, are due within a year of that publication (EY). The Tax Authority has said it is already building the electronic systems and training the staff that will run the tax (Oman Tax Authority). The shape of compliance will firm up well before the first invoice of 2028 goes out.
Second, good records are not retroactive. When the first tax year arrives, you will want a clean, year-long picture of what you earned and what you can deduct. You cannot reconstruct that neatly in December 2028 from a folder of mismatched PDFs and a handful of bank statements. The habit you want in place by 2028 is one you build through 2026 and 2027, while the stakes are still zero.
There is a planning angle too. Knowing the threshold this far ahead lets you see whether a strong year will tip you over the line, and by how much, while you still have room to act. A 5% bill on the slice above OMR 42,000 is not frightening by itself. Being blindsided by it is the avoidable part. If a single large project is what pushes you over, you can decide in advance how to time the work and the invoice, instead of reacting after the fact.
How a high earner should start tracking income toward the threshold
You do not need an accountant on retainer in 2026 to get ready. You need a running, accurate view of your income. A few concrete moves:
Keep one source of truth for income. Every proposal, invoice, and payment in one place beats a hunt across your inbox, a banking app, and three desktop folders.
Record amounts in OMR, even when you bill in another currency. The threshold is set in rial, so a USD or GBP invoice has to be converted before you know where you stand. Log the rate and the date you used.
Separate gross from deductible as you go. Tag the categories the law recognizes so your taxable figure is something you can read off, not something you reverse-engineer in a panic later.
Watch the line through the year, not at year end. If you are running toward OMR 42,000 by September, you have time to plan. Find out in hindsight and you do not.
Keep proof. Signed contracts, sent invoices, and recorded payments are what stand behind a number if anyone ever asks to see it.
If you invoice clients in more than one currency, this gets fiddly fast, and the conversion step is where most people lose accuracy. A clear method for multi-currency invoicing is worth setting up now rather than piecing together in 2028.

The wider GCC picture: is your country next?
This is the question every high-billing independent in the region is now asking, and the honest answer is a measured one. Oman is first. No other GCC state has announced a personal income tax on individuals. Reading Oman's move as a domino that topples the rest would be guessing, not reporting, so treat the "who is next" chatter as exactly that.
What is true is that the region's tax direction has already shifted at the business level. The UAE brought in a federal corporate tax of 9% on taxable income above AED 375,000, with a 0% band below that figure, for financial years starting on or after 1 June 2023 (PwC). The UAE still has no personal income tax. If you run your freelance work through a UAE company, the rules that touch you are corporate, not personal, and the UAE corporate tax guide for freelancers walks through where the line falls.
Saudi Arabia is its own case. It still does not tax individual employment income, but it does run mandatory social insurance through GOSI, which is a real cost on earnings and easy to overlook when you compare countries on headline tax alone. If you work there, GOSI for Saudi freelancers explains who pays and how much.
The sober takeaway is that the Gulf is not abandoning its low-tax model overnight. Oman has taken a specific, capped step aimed at high earners, and the rest of the GCC has not followed it. Plan for the rules that exist where you actually live and bill, and watch the official announcements rather than the rumors.
What this means for your records, wherever you bill
Strip the policy debate away and the practical job is the same whether you end up liable or not. You want to know your real annual income, in the currency that matters, with the deductible parts marked and the proof attached. That picture is useful for an Oman threshold check, a UAE corporate filing, a VAT return somewhere else, or simply knowing what your business actually made this year.
The freelancers who will find 2028 painless are the ones whose income is already legible to them today. The ones who will struggle are the ones reassembling a scattered year under time pressure. The deciding factor is not how much you earn. It is whether your records can answer a plain question on demand: what did I make, and how much of it counts.
Delivvo handles the unglamorous part that ends up mattering. It keeps your proposals, contracts, deliveries, approvals, and invoices in one branded home, so your income and your deductible categories are already consolidated when threshold math or a future filing comes due. The money still runs through your own payment gateway at a 0% platform cut, so the platform never touches your funds. See how it works →
The Gulf's tax-free era is not over for everyone, and it may never reach most people. For Oman's top earners, though, the clock to 2028 is already running, and the cheapest thing you can do right now is keep clean books.
