OTS recommends simplification of PAYE The Office of Tax Simplification (OTS) says the PAYE system needs to be reviewed and has suggested HMRC offer better guidance for SMEs in regard to compliance with the tax system. OTS tax director Bill Dodwell said start-ups need advice on taxes, licences and pensions to beat red tape, commenting: “Many new businesses are formed without sufficient help and guidance. This can lead to mistakes being made, resulting in substantial costs or penalties.”
