Business Tax Returns questions
Answers for Omagh clients. Your accountant can go into detail for your situation.
Payment is due 9 months and 1 day after the end of your accounting period; the CT600 return itself is due 12 months after. Larger companies with profits over £1.5 million pay in instalments.
The partnership files its own SA800 return showing total profit and each partner’s share. Each partner then reports their share on their personal Self Assessment return and pays Income Tax and National Insurance on it.
UK residents must report and pay Capital Gains Tax on a residential property sale within 60 days of completion using HMRC’s online service, and then include the gain on the Self Assessment return for that year. We prepare both.
