What is an SA800 Form?

Updated: Aug 16, 2023

SA800 Form is a self-assessment tax return document specifically for a partnership. The SA800 form is eight pages long and is used to declare income and disposals from a partnership with HMRC. In addition to the SA800, additional pages may be required to detail the partnership's various sources of income. The SA800 is created after the SA400 has been processed by HMRC and is normally submitted by the partnership's selected nominated partners.

What's Included in the SA800?

The SA800 Form is divided into several sections, each of which pertains to a specific aspect of the partnership business income. The first section of the form is used to report the gross income, which includes all income received from self-employment, such as sales, fees, and commissions. The second section is used to report expenses incurred, such as office expenses, travel costs, and equipment purchases. The third section is used to report any capital allowances, which are deductions that can be claimed on items such as machinery and equipment used in the business.

HMRC have created various sections on the SA800 to gather the information they need about partnership business, trade, and professional income. SA800 consists of the following sections:

● Partnership business and investment income.

● Partnership trade and professional income.

● Declaration of partnership.

● Other information.

You will need your partnership UTR number when submitting your SA800.

You have to know

In addition to the main SA800 form, each affiliate must also file a personal tax return (SA100) and the SA104 supplemental pages to declare their share of profits or losses. Filing the SA100 and SA104 will determine how much tax, if any, individual partners will have to pay. This is often overlooked and results in affiliates being fined by HMRC. A separate page must be completed for each partnership to which someone belongs.

In order to complete the SA800 Form, individuals (partners) must keep accurate records of their income and expenses throughout the tax year. This may include invoices, receipts, bank statements, and other financial records. These records must be kept for a period of six years, in case they are needed for an HMRC inspection.

How Do I File SA800?

The SA800 partnership tax return is normally filed online using either third-party accounting software or HMRC online. You have the option of downloading a copy of HMRC's SA800 and then posting the completed form instead of submitting it online.

You Have to Know

In the case of profit or loss in the partnership business, the division must comply with the terms of the articles of association. In most cases, the proportion is the same for each partner, although this is not always the case.

SA800: Tax Payment Deadlines

The deadlines for paying your tax bill are:

● January 31st for taxes you owe for the previous tax year (referred to as a “balance payment”) and your first prepayment (i.e. prepayments on your tax bill).

● July 31 for your second deposit.

SA800 Penalties for Late Filing of Tax Returns for Partnerships

If you fail to file your SA800 partnership tax return by your chosen paper or online deadline, each member of the partnership will have to pay a penalty of £100 during the tax return period unless you have a good reason for the delay. If partners still do not submit their SA800, each partner will be charged:

● Delay of more than 3 months - a penalty of £10 per extra day if the SA800 partnership tax return is late by a maximum of 90 days (£900).

● Delay of more than six months – a fixed penalty of £300.

● More than 12 months late – another flat fee of £300.

You Have to Know

You must fill out the partnership tax return in full. If you have a disability that makes it difficult to complete the return, HMRC can help you complete the form. Partnership businesses may also have to submit the following form (depending upon the circumstances):

· SA801 Partnership UK Property

· SA802 Partnership Foreign Income

· SA803 Partnership Disposal of Chargeable Assets

· SA804 Partnership Saving Investment and Other Income
