Federal & State Tax Returns | Global Prime Taxation

A return accomplished, not just a filled-in form.

Filing gets risky when you live or work in more than one state, own a business, or need careful refund calculations and deadline management. Our experts look at the whole picture — every state, every income source and every deadline — and work out the right way to file for your situation. GPT professionals review your part-year and full-year federal and state returns together, so they agree with each other.

We are an IRS Authorized e-file Provider, so your return goes straight to the IRS electronically, and we check it carefully first so it is accepted the first time.

Frequently asked questions

When is the federal filing deadline?

For most people, federal returns are due on April 15. If that date falls on a weekend or holiday, the deadline moves to the next business day. You can request an automatic six-month extension to file, but any tax you owe is still due by the original deadline.

I moved to a new state during the year. Which states do I file in?

Usually both. You typically file a part-year resident return in each state you lived in, and sometimes a non-resident return in a state where you worked but didn't live. We work out which returns you need and make sure income isn't taxed twice.

Can you file returns for previous years?

Yes. We prepare and file prior-year returns for people who missed a year, and we can check whether you're owed a refund from a year you didn't file.

How do I know my return was accepted?

After we e-file, the IRS and states confirm acceptance electronically. You'll see the status in your GPT client account.
