Taxes Management Act 1970 section 12ABA

Amendment of partnership return by taxpayer

Section 12ABA allows a partner (or their successor) who filed a partnership return to amend that return within a specified time limit, and requires HMRC to update each partner's individual or company tax return accordingly.

• The partner who filed the partnership return, or their successor, may amend it by notifying an HMRC officer
• Amendments must be made within 12 months of the filing date
• HMRC must notify each partner and amend their personal or company tax returns to reflect the partnership return changes
• The filing date depends on whether the partnership includes individuals (generally 31 January following the tax year) or companies (determined by separate statutory deadlines)
