If VAT is required, payments should be made every 3 months. VAT refund is sent to HMRC within 37 days starting from the end of the 3 months.

Limited Companies

Limited companies must report annual tax returns to Companies House, compile legal accounts, report declaration to HMRC, and register with VAT.

Partners must pay national insurance, prepare a personal self-assessment and tax return, and register with the VAT system if their income exceeds £ 85,000. In limited partnerships, a self-assessment tax return must be prepared every year. If company earnings exceed the threshold, they must register.
