How to file Korean income tax return for last year
« on: January 26, 2012, 10:22:27 am »
So I started working for a Korean public school in March 2010 and I have never filed a Korean income tax return (I'm from Canada and don't get the two year exemption). AFAIK my school makes all the necessary deductions and other than the resident tax bills I receive from my gu office I haven't heard anything personally about Korean taxes. I'm a bit late being proactive about this but how does one file taxes late? It would be a good idea as:

1. there's a penalty for filing Korean tax return late.

2. you may be eligible for a refund.

3. Canada may require proof I paid taxes elsewhere in the future.

Form 40-4 from the NTS website seems like the form to fill out for single income taxpayers.

http://www.nts.go.kr/eng/resources/resour_41.asp?top_code=R001&sub_code=RS04&ssub_code=RSD1

I'd need proof of income from my school and print out debit/credit card expense summaries from my bank at the least.

Any other info I should know about filing late taxes?

Its tax time again and my new school refuses to do the taxes for me this year. Been given a 6 page long form that is a mighty wall of text and have been told "do it yourself."

Previous schools did it for me, so I am literally clueless about how to even tackle this behemoth.

UK and US tax returns were scary enough in the past...this one looks like it takes the biscuit when it comes to that though...

I started working in Korea in September 2012. When do I have to start filing taxes? I plan to live in Korea for a long time. Do I not have to do taxes until I've worked a full year?

When is Korean tax season?? When is the deadline?

I am Canadian and Canadian tax season ends in April, I believe (I usually file early, in Feb or March) and I want to figure out what to do with Korean taxes before I deal with Canada.

I really want to try doing it on my own before asking my coteachers. I can't seem to find much information online about doing Korean taxes. Just how to do Canadian taxes while in Korea.

if you're planning on staying for a while, file for non-residency in canada. just google it and send them the form.
use google to search the site

replace 'XXXX' with your search term

I have a tax-free savings account in Canada (which I can only keep if I file Canadian taxes). I don't really want to take it out, and a portion of it is locked for a year (locked until August 2013), so I can't take that part out anyways.

I am planning on keeping my residency in Canada for the time being because of this and some other reasons.

Whether or not I keep my Canadian residency, I need to file Korean taxes anyways. My question again is, how do I file Korean taxes?

Speaking as a former accountant if you file taxes in Canada be prepared to have to pay tax on your earnings in Korea also...

Is this so you can get the forms from NTS, like your debit card and health payment information? If so, you can use your online banking certificate.
