About Us
An advisory practice focused on US tax and business matters for clients in the United States and around the world.
Saad Ayub
Saad Ayub is the founder of SZ World and works directly with clients on US tax and business matters. He holds an IRS Preparer Tax Identification Number (PTIN), is an IRS Certifying Acceptance Agent (CAA), and is an IRS Authorized e-file Provider.
His work centres on helping entrepreneurs, small business owners and non-US residents understand their US obligations — from choosing a business structure and obtaining an ITIN, to preparing and filing federal returns and staying on top of annual compliance.
Many clients come to us from outside the United States. We understand the questions that arise when you run a US company from abroad, and we explain the answers clearly so you can make informed decisions.
Credentials
These credentials are issued by the IRS to individual practitioners. They do not imply IRS endorsement of our services.
Our Mission
To make US tax and business obligations understandable and manageable for every client, wherever they live.
Our Approach
Defined scope, published fees, realistic timelines and honest advice — including telling you when a matter needs a lawyer or CPA.
Our Commitment
Confidential handling of your information, prompt communication and careful, accurate work on every engagement.
Clients we work with
- Non-US residents who own or plan to form a US LLC
- Entrepreneurs and freelancers with US business activity
- Small business owners who want reliable filing support
- Individuals who need an ITIN for US tax purposes
Clear boundaries
We are a consulting and tax preparation practice, not a law firm. We do not provide legal advice, represent clients in court, or guarantee decisions made by the IRS or any government agency. When a matter requires an attorney or another licensed professional, we will tell you.
