Re: Week Numbers for Tax Year

I meant to add, you should ask your client which tax week he is actually
using.
If he is counting a week commencing 01 Apr 2007 as week 1, then he is
wrong. No question about it and an IR inspection could prove costly.

You also said that the week with 06 Apr 2007 in it is considered to be
the last week of the old tax year.
Depending upon which day of the week your client makes his payments. It
could have been week 53 of the previous year for him for this year, but
it will not be next year.

The start point is fixed as I have said in earlier emails and it is 06
April each year. It never varies. It doesn't matter what day that falls
upon.

Hi Mike

Although I said I used Sage for a quick check up (saved me hunting
around the IR website), Sage operate exactly as per the IR Rules,
which is the same as Rick and I did when compiling our formulae.

ISO tax weeks have week 1 as the first week which contains a
Thursday.This year, Ist Jan happened to be a Monday, hence the start
of ISO week 1 was 01 Jan 2007. Had 1st Jan occurred on a Friday, then
week 1 would have started on 04 Jan 2007.

You cannot therefore use a constant offset for Tax week number
compared with ISO week number.
The Tax week numbering always starts from 6th April in the every year,
regardless of which day of the week that happens to fall upon. For
2007, it happens to fall on a Friday.

How do you calculate that?
I just loaded Sage Payroll, and for 07 Jun 2007 it gives Tax week 9.
As Sage is probably the widest used payroll package in the UK, I
don't think they will have got it wrong<g>
Tax week 10 commences on 08 Jun 2007

I accept I may have lost the week number plot :-)

Some more information:

This week number routine is required for an Excel invoice *** that
I use. I always use ISO week numbers on my invoices (this week is ISO
week 23).

My main client says they use Tax Year week numbers, but it seems that
their system assumes that the week with 1 April in it (ISO week
number 13) is Tax Year week 1. This week (ISO week number 23) would
then become my client's Tax Year week number 11.

If we accept that the week with 6 April 2007 in it (2 - 8 April, ISO
week number 14) is the first week of the new Tax Year, then this week
(ISO week number 23) must be Tax Year week number 10.

However, (according to Sage) it seems that the week with 6 April 2007
in it is considered to be the last week of the old 2006-07 Tax Year,
and ISO week number 15 (9 - 15 April) is the first week of the new
2007-08 tax year. This week (ISO week number 23) then becomes Tax
Year week number 9.

I suppose it doesn't help that ISO week numbers run from Monday to
Sunday, whilst Tax Year week numbers appear to run from Friday to
Thursday (if Tax week 10 commences on Friday, 08 Jun 2007, as stated
above).
