Witholding under 2 different IDs

Hi,
I got my ARC at some point last year, but I had already started working the moment my employer applied for it, 3 or 4 weeks earlier.
As a result, I received 2 Tax withholding statements: one under a bogus ID, made by my birthdate plus 2 letters, and including just a few weeks of income; and the other one with my ARC#, including the income from then to the end of the year.

Questions:

  1. Do I need to somehow file taxes on the first ID?
  2. If yes, how? I don’t see a way to file without a valid national ID.
  3. If not, why did my company withhold 18% of my income? Is there any way to get a refund for that? Using the deduction, my income would qualify for a full refund of what was withheld.

Thanks

I think the tax office will link your old one and new one together under a unified number , it should not be a problem. Go into the revenue office they will help you .

Are the two letters the first two letters of your name?

John…maybe JO

Or Smith…SM

That is how i have to add my parents as dependents when i file taxes so it is a thing they do here if someone doesnt have an ARC.

They are the first 2 letters of my last name.
And I bet I can add a dependent with that kind of ID, but I don’t think I can file a separate return under that ID.

Thanks. However, here’s the problem.
As I mentioned, part of the income was “made” (not received) while I was still waiting for the ARC. The employer back then reassured me that it was all right, but … was that really legal?
I am afraid to file a tax return for the combined amounts and trigger some audit that would trigger some other (immigration) audit.

Plenty of people without ARCs have to file tax report, so should not be an issue

Did you already have the work permit at that point?

Let’s say that the Work permit was issued on the 12th day of a certain month last year and I did some activities in the 3 or 4 business days between the application and the issue.
The ARC came in the 2nd week of the following month.

The first Tax withholding statement out of the 2 I have states as “Period of Income” the month of my work permit issue (not a specific day of the month).

I think the chance of an actual problem is quite small as revenue authorities generally just care about getting the tax owed on the statements .
Somebody else may have a more informed take but they has been my experience to date.

I believe the key date for tax purposes is the date when salary is actually received on your account

that’s actually a “proper” Tax ID (TIN) for foreigners here without Unified ID (i.e. ARC number to make is simple).

  1. Best to ask tax office, however I reckon by filing with your ARC only won’t be problems
  2. there is the option online to file via ARC+passport, or just go to the tax office, they r quite helpful tbh in the main one new taipei main station (dunno where u r based, so talking only by my personal experience)
  3. that because… TW tax system and interpretation, something I am actually fighting for with the MOF and NTB. Rn NTB considers all foreigners in TW, regardless of their residency status (so including APRC holders) as non tax residents until they actually reside in the country for 183 days per calendar year. So all tax declaration obligors (very ugly name for whomever need to declare paying u and hence withhold at the source) just by default withhold the non-resident rate of 18% until you either can show you are “actually” resident or if you get a gentlemen agreement with them not to do that. The extra money withheld will be deducted from your tax note and so it will be refunded to you if in credit or just discounted, they won’t get lost, but there will be a considerable lag for this.

Never ever happens. Just go talk to them.

I just noticed your username, you sound Italian like me, don’t worry, go to the tax office and talk to them, they won’t Scass u cazz too much as long as you are willing to pay ur taxes (which it seems you are), so it’s in good faith

Thank you all for your answers.
Problem solved.
Apparently, both IDs are linked to my passport number, so the Tax office could assess income from both withholding statements to me.
