Its very common in Small Businesses for the Directors Loan account to be overdrawn creating a Directors Loan.
If the loan isn’t repaid within 9 months of year end the company will pay temporary additional Corporation Tax at the rate of 25% on the balance outstanding.
Section 455 CTA 2010 liabilities must be included in a company’s CT600 tax return. The S455 tax forms part of the calculation of tax payable by the company under Paragraph 8 Schedule 18 FA 1998.
A claim to relief under Section 458 is a claim for relief against the original tax charge for the AP in which the loan was made. The time limit for the claim is four years from the end of the financial year in which the loan is repaid, released or written off. COM53120
Until now there has been no set format for writing to HMRC to reclaim the s.455 tax but now you must use form L2P to enable a close company which has paid tax on a loan to a participator to reclaim that tax once the loan has been repaid, released or written off.
