The SA800 and every partner’s return submitted.
| Item | What you need to know |
|---|---|
| Partnership return | SA800, filed by the nominated partner |
| Online deadline | 31 January after the end of the tax year |
| Partners’ returns | Each partner files their own return, including partnership pages |
| Late filing | A £100 penalty can apply for each partner if the SA800 is late |
| Tax basis | Profits taxed on the tax year basis since basis period reform |
A partnership does not pay Income Tax itself. Instead, it files a partnership tax return showing the profit and how it is shared. Each partner then pays Income Tax and Class 4 National Insurance on their share through their own Self Assessment return.
If the partnership return is late, a penalty can be charged to every partner, so one missed deadline multiplies quickly. Profit shares on each partner’s return must also match the partnership statement exactly.
As profits grow, a limited company can sometimes be more tax-efficient. Our business tax planning service compares the options using your figures, and our limited company accountants can help if you decide to incorporate.
