Hi,
Im 3d artist from Czech Republic. i filled w-8ben here. To claim tax treaty benefits I need to obtain an ITIN number from IRS.
I know i must send:
1) W-7 form
2) notarized passport
3) i have document from turbosquid, where they write that i uploaded my models and may have some sales.

document and passport i have, now I need help with filling this W-7 form

im nonresident alien required to obtain ITIN to claim tax treaty benefit,
so I fill a)

my question: need I to fill h) also? if yes what i must write do dotted line ? "exception 1"?
treaty country is czech republic, but treaty article number? i really dont know :(

No need to fill in h).

Download IRS Pub 901 (Tax Treaties) from www.irs.gov to find the article you need.

and when i filled this H and wrote "exception 1" ?
am i wrong? :( i already sent it :(

i downloaded pub 901 but i found nothing to czech republic, but maybe i only dont understand this

No, exception 1 is fine. If you filled in H, it should not cause a problem.

If you could find nothing for Czech Republic, that means no tax treaty exists.

thank you very much,
i will wait now and hope iŽll get ITIN

Glad to help!
