Thanks for your work!  Adding a new package is a great first
contribution.  Here are some suggestions:

We don't usually create new files for specific packages.  I'd suggest
putting this definition into finance.scm.

What I would do here instead would be to let-bind tax-year and
ots-version in the body of the define-public clause, so that it's only
defined there.

Here, you shouldn't directly talk about gcc, since the compiler name
might be different when cross-compiling.  We have a procedure for that,
cc-for-target, an example use would be (invoke "make" (string-append
"CC=" ,(cc-for-target))), but you would need to replace the quote
'(#:phases ...) to a quasiquote `(#:phases ...). You should have a look
at quote and quasiquote in the Guile info manual, node "Expression
Syntax".

By the way, we now use g-expressions instead of s-expressions for
phases, but that might be too big of a commitment for a first
contribution.  Someone else can adjust that part after these changes.
You can still have a look in the Guix manual for the G-Expressions node
if you're so inclined.

Ditto.

You shouldn't use specification->package in package definitions, as
that's pretty costly (it needs to scan the whole package list for
it). You should instead make the package variable available itself by
using (#:use-module (gnu packages gtk)), and use the variable gtk+-2.

There's no need to add gcc to the list of native-inputs, it is included
by most build systems, glib-or-gtk included.
