I Just Paid Taxes!

From: "andrew cooke" <andrew@...>

Date: Thu, 10 May 2007 21:25:12 -0400 (CLT)

I just paid my income tax for last month!  This is a major achievement -
I'm being paid in dollars by an American company, but am an English person
with permanent residency in Chile.  I think it went OK.  The process is:

- Mulesource cable me dollars
- Dollars arrive in the bank's account
- No-one tells me anything
- Eventually I go to the bank and ask
- The bank agrees that they have my money
- The bank transfers my money into a dollar fund under my name
  (this is the date on which I receive the payment, I believe)
- I record the payment in a little book of printed slips that I have
  (in duplicate) along with the day's dollar/peso conversion rate
- At some later I point I argue and plead and eventually get to transfer
  money from the dollar fund to my current account, in pesos, for a fee.
- Before 12 days after the start of the month after the month in which I
  receive the money(!) I go to http://www.sii.cl
- There I fill in form F29 as shown in the video at
  giving the amount in pesos.
- That form calculates my tax (10%) and forwards me to my bank's web page
- At my bank's web page, I confirm payment.
- Next May I will enter my total earnings in another online web page and
  will receive, hopefully, a refund of some of what I have paid.

Cool or what?  Makes paying taxes a pleasure :o)


Happy to be fined!

From: "andrew cooke" <andrew@...>

So I forgot to pay my tax on time.  And I after looking at an old form of
Paulina's realised I filled in the wrong box on the form last time.

I managed to correct the previous month (same amount, so it seems OK). 
And then I submitted last month's and it automatically calculated my fine!
 The whole process is so stressful - you have no idea how alien another
country's tax system is until you try to pay - that just getting the fine
to come up correctly felt like a huge success...

For future record - it's 84 b, not 84 a (and you work out the 10% yourself).


Easier Online Procedure

From: "andrew cooke" <andrew@...>

Date: Sun, 6 Apr 2008 20:45:29 -0400 (CLT)

Until now I have been paying my AFP (obligatory pensions) contribution in
person, filling in a yellow slip and a cheque, and queueing once a month
at a bank-like payment place.  I couldn't use http://www.previred.cl (I
thought) because they force you to pay ISAPRE (health) too, and I was (1)
paying that automatically through my bank and (2) paying a different
amount from that calculated by previred because it's a joint insurance
with Paulina.

But today I just worked out how to do everything online.

First, go to http://www.safp.cl/safpstats/stats/inf_afiliados/calcos.html
and calculate the costs.  That's only the administration charge, but they
display the "tope" (the upper limit, which I exceed, and I never know
exactly what it is, since it changes daily).  So add the charge to 10% of
the tope.

Then go to http://www.previred.cl and (once logged in) select the "direct
pay" button below the "usual" buttons.  This lets you pay just the AFP! 
So fill in the amount calculated above, and everything is OK (assuming
that the ISAPRE is paid automatically and tax is done through
http://www.sii.cl )
