Self-Assessment Tax Returns
Self Assessment is the system HMRC uses to collect income tax and National Insurance from people whose income is not fully taxed at source through PAYE. If you are self-employed, a company director, a landlord, or have other untaxed income, you must file a personal tax return each year. The system has several features that catch first-time filers off guard — most notably the payments on account regime, which can make your first January tax demand significantly larger than expected. This guide explains exactly who must file, every relevant deadline, how payments on account work, and what penalties apply if you miss them.

Time to Pay Arrangements With HMRC
If you have a tax debt you cannot pay immediately — whether self-assessment income tax, VAT, PAYE, or another HMRC liability — you may be able to agree a Time to Pay (TTP) arrangement with HMRC. A TTP allows you to spread the debt over monthly instalments. HMRC is generally willing to agree TTP if you contact them before enforcement action begins, but defaulting on an agreed plan can have serious consequences.
