Monthly payroll cycles, quarterly VAT returns, and the rules that trip up businesses when they fall behind.
Payroll is the monthly cycle of calculating employee pay, deducting tax and National Insurance, and reporting to HMRC.
VAT is a tax on turnover, collected in your sales and paid to HMRC quarterly. It can be a cash flow shock if you haven't planned for it.
Most businesses file VAT returns every three months. The deadline is usually one month after the quarter ends.
You collect VAT from customers (output). You reclaim VAT paid to suppliers (input). The difference goes to HMRC, or HMRC owes you a refund.
VAT you owe is money you must set aside from sales. Missing this can create a nasty surprise when the return is due.
Making Tax Digital (MTD) is HMRC's requirement to keep digital records and file returns via compatible software.
MTD for VAT applies if your turnover is over the VAT threshold (currently £85,000). You must use software that connects to HMRC to file. Some businesses voluntarily register below this threshold.
Payroll data must be kept digitally and reported to HMRC monthly through compatible software. Your payroll software almost certainly already handles this automatically.
HMRC penalties apply. First missed return incurs a £200 penalty; further misses can escalate. Regular late returns can attract penalties per return. Outsourcing payroll and VAT helps avoid this risk.
MTD is specifically HMRC's filing and reporting requirement. Digital bookkeeping in Xero or QuickBooks is a prerequisite for compliance, but not the same as submitting MTD returns.
