Self Assessment payments usually centre on 31 January. That date is used for the balancing payment for the previous tax year and, where payments on account apply, the first payment on account for the current year. A second payment on account is normally due on 31 July. Interest can apply if payment is late, so the date matters for cash flow as much as filing. HMRC rules depend on your circumstances, so check your online account before paying.
