Late filing penalties for Self Assessment Tax Returns for the 2010/11 years and onwards.

The new penalties for late Self Assessment returns are:

* an initial £100 fixed penalty, which will now apply even if there is no tax to pay, or if the tax due is paid on time;

* after 3 months, additional daily penalties of £10 per day, up to a maximum of £900;

* after 6 months, a further penalty of 5% of the tax due or £300, whichever is greater; and

* after 12 months, another 5% or £300 charge, whichever is greater. In serious cases, the penalty after 12 months can be up to 100% of the tax due.

New penalties for paying late are 5% of the tax unpaid at:
* 30 days;

* 6 months; and

* 12 months.

Interest will also be charged on top of these penalties.

The tax return deadlines remain  – 31 October for paper and 31 January for online returns. The deadline for paying any tax due also remains the same at 31 January.
