Tax bills not worth the effort
For many years HMRC adopted a policy of not assessing tax if the amount involved was small. 40 years ago the limit was £30 and eventually became £70. However,
that was in the days when the Inland Revenue, as it was then, had to go through the rigmarole of manually writing or typing an assessment, posting
it to the taxpayer and notifying the collector of taxes to issue demands. The so-called assessing tolerance disappeared with the introduction of self-assessment
in 1996. However, HMRC has found it necessary to renew this old policy, but not in all situations.
If you submit self-assessment tax returns you’ll have to settle the tax bill that results, however small the amount. HMRC routinely make adjustments to
eliminate very small debts, typically no more than £2. The legislation gives HMRC management powers to do this. It can, but very rarely does, use the
same rules to write off larger sums, but it’s not open to negotiating a debt down.
HMRC will seemingly write off a debt if it loses track of someone who owes it money. This is usually no more than a temporary reduction. So if you change
address when HMRC eventually tracks you down it will reinstate the tax charge and add interest to the bill.
Currently HMRC issues informal tax calculations known as P800s. The idea behind these is that rather than force individuals with simple tax affairs to
complete self-assessment returns HMRC uses the information it has to decide if you you’ve over - or underpaid tax. It then asks you to pay or refunds
you. The debt is not enforceable and so if you refuse to pay HMRC is likely to send you a self-assessment form to fill in or, if you have income that’s
taxed through PAYE, adjust your tax code to increase the amount you pay on your salary etc.
P800s are often inaccurate and you should check them, especially if they include estimated figures (savings or investment income is usually estimated).
HMRC must adjust the P800 if you provide it with the correct figures.
HMRC simple assessments
A few years ago legislation was introduced to allow HMRC to issue simple assessments in certain circumstances where a P800 is not suitable. Tax payable
on a simple assessment is enforceable, but they too often include estimates and should be checked. Unlike P800s you must formally notify HMRC within
60 days if you disagree with the figures.
HMRC’s practice of not issuing assessments or P800s for small amounts is back. It should not assess you if you owe less than £50. If you receive such an
assessment/ P800 call HMRC on the number shown on the document and ask for the debt to be cancelled. It will usually agree to this.
If you’ve completed a self-assessment return you must pay the demand, assuming the amount requested ties up with your calculations, no matter how small
it is. However, if the demand is in respect of a Form P800 or simple assessment and is for less than £50, HMRC ought not to have sent it. It will usually
cancel the charge if you ask.
