How to open a company in Great Britain?

I am not sure if you can run a sole proprietorship while staying in Poland. It seems to me that in order to be self employed you must stay in the UK for at least 183 days a year in the UK. It's best if you consult a company that deals with setting up a company in England and they will surely give you detailed information. Regards.

You cannot run a sole proprietorship in the UK while permanently in Poland. But I will explain step by step what you have to do if you can stay there for at least 183 days a year.

Self-employed is the easiest company to set up in the UK. To open a business in this form, you must be resident in the UK for at least 183 days a year and have a NIN number, which means that you are covered by compulsory insurance.

When running a business in the UK, you will have a number of responsibilities as self employed:

1. Documentation of revenues and expenses, invoices and costs related to your activity;

2. Submission of tax returns (Tax return) by January 31 of each year in the online version and by October 31 in the paper version;

3. In addition to income tax, you must pay National Insurance contributions (Class 2 and 4 National Insurance Contribution);

4. If your company's annual turnover exceeds the threshold (£85,000 in the 2019-20 tax year), you should register for VAT. However, you can register even if the turnover drops or does not reach this level;

5. If you work in the construction industry as a subcontractor or contractor, you must register with the Construction Industry Scheme (CIS);

6. Paying Income Tax to HMRC.

As in Poland, you will be able to deduct some of the expenses incurred, but the UK tax office has detailed rules on what can be deducted. You will have to familiarize yourself with the so-called "allowable expenses", in which it is explained in detail what counts as tax deductible costs. You can include in costs all office expenses, renting an apartment or premises for business activity, all travel and business transport, marketing and promotion, and staff costs (bonuses and contributions to pension and social insurance). Each industry is different and has its own tax deductible costs.

You shouldn't have any problems starting a sole proprietorship. You can register online, even from Poland. by clicking on the link below you will enter the government registration portal where you enter your email address. The page will then guide you through the entire procedure.

Of course, you can also choose the traditional form of registration, i.e. a paper version sent by post. All you need to do is fill out a special form, print it and send it to the appropriate office. Before starting to fill in, prepare all the necessary information, because it is impossible to save the already entered data and return to them after some time.

If you want to deal with trading, you register under the link for sole trader. You have the link below.

Many people trade under their own name and this is the name they choose for their company. Of course, the choice is yours, but remember that not all names can be registered:

1. Existing trade mark company names;

2. Your name must also not contain a word or phrase that suggests a relationship with government or local authorities, unless you have specific permission;

3. Business names 'limited', 'Ltd', 'limited liability partnership', 'LLP', 'public limited company' or 'plc';

4. Vulgar or offensive names.

Once you've gone through the whole registration process, you'll receive a special letter from HMRC which will contain your unique 10-digit taxpayer number. Your online account will also be set up so you can access government services.
