If you’re self-employed or a landlord, Self Assessment can feel confusing and expensive—especially in January! This guide explains how payments work, what “payments on account” are, and how to plan ahead so you’re never caught off guard.
Self Assessment requires you to pay tax on income outside of PAYE, and understanding the process is crucial to avoid late penalties or unexpected bills. In this guide, we cover:
-
Payments on account: Prepayments for the next year’s tax if your bill exceeds £1,000.
-
Balancing payments: Top-ups for any remaining tax owed, due by 31 January.
-
Key dates: When and how to pay to stay compliant.
-
Practical tips: Set reminders, save monthly for tax, and pay online through HMRC.
Whether you’re filing for the first time or need a refresher, this article explains Self Assessment payments clearly and offers advice on planning ahead. For personalised help with your tax return or payment strategy, get in touch with us—we’re here to make Self Assessment stress-free.
