The 12 days of Christmas or Taxmas (a reworked xmas carol)

 First line: On the first day of Taxmas the taxman sent to me:

- A rejection of my time to pay plea

The second verse:

On the second day of Taxmas, the taxman sent to me
- Two demand notes and
- A rejection of my time to pay plea

...and so on.
The last verse is:

On the twelfth day of Taxmas, the taxman sent to me
Twelve months to pay my debt
Eleven penalty charges
Ten confusing statements of account
Nine booklets on 'How to complain'
Eight explanatory leaflets
Seven website links
Six excuses for the delay
Five more queries
Four VAT returns to file
Three blank tax returns
Two demand notes and

One reluctant acceptance of my time to pay plea.

When I had the idea for this I checked online and found there was an old US version of the 12 days of Taxmas. Mine was developed independently.
