my really-quick calculation is if you have $7000 in business income
(after deductions for expenses) you'd owe $989 in SE tax.
so, for next year, if you earn any more than just about this, you'd
have a total tax liability of >$1000 including the SE tax, so, in
principle, you need to make estimated tax payments equal to either 90%
of your 2003 liability or 100% of your 2002 liability, or about $1000
for the year.
now, if you don't make them, I think the penalty for not paying that
$1000 in advance is about $37, at least according to this year's form
2210, so you can balance that cost against the time & effort required
to make estimated tax payments.
note, of course, that I am not a lawyer or an accountant, so you'll
have to make your own decisions. much more information can be found
in IRS publication 505 at http://www.irs.gov/pub/irs-pdf/p505.pdf,
which says you "MUST" make estimated tax payments if you expect to owe
more than $1000, but I think that only means that "if you don't, you
may be required to pay a penalty", not "if you don't, we will throw
you in jail".
note also that if you don't have any income yet for 2003, you
definitely don't need to pay estimated tax yet; you can wait until the
quarter when your projected income for the year will be enough that
you will owe tax over the $1000 threshold.
let me know if you have further questions!
