Every business must lodge an annual return, whether it is a sole trader, partnership or company, and even when it has a loss or no tax to pay.
Tax year and deadline
31 March of the following year, with payment made when the return is lodged. Approved tax-agent programmes have later dates: 30 June (sole traders and partnerships making taxable supplies), 31 July (companies making taxable supplies) and 31 October (non-taxable supplies).
Filing step by step
Businesses under the presumptive tax file a one-page return and pay with it.
Other businesses file the five-page Business Tax Return and pay once, reporting income and expenses on a cash basis.
Monthly Pay As You Go instalments use the Business Activity Statement (BAS) by the 21st.
Penalties for filing or paying late
A return filed late carries additional tax under the Revenue Administration Act 2009, s.42: for a small business (turnover under SR 1 million) SR 500 plus SR 50 for each week or part of a week, for a medium business SR 1,000 plus SR 100 a week, and for a large business SR 5,000 plus SR 500 a week. Tax paid late attracts a further 10 % additional tax (s.44) and simple interest at the Central Bank's quarterly average prime lending rate plus three percentage points (s.41). Interest is charged in addition to additional tax.
