How we


Starting the cooperation

Should you be interested in our services, please contact us through telephone or e-mail to provide the data necessary to enter into the bookkeeping services agreement. Such agreement, as well as the required power of attorney, can be completed in our office or at the office of our Client. J&J Tax House will then file all required documents to the chosen Tax Office and Social Security Office (ZUS).

If you are planning to start business activity, please contact us so we could schedule an appointment and invite you to our office. Such meeting will be an opportunity to fill all the required tax forms and to choose the best form of taxation for your new business.

Document filing

After signing the bookkeeping services agreement the Client declares (by phone or e-mail) readiness to filing monthly accounting evidence (by the 15th day of each fiscal month).

Clients can issue the documents personally, during our office hours (10 a.m. – 3 p.m.), or have the documents collected from your company by our employee. We also use postal and courier services. Details are arranged by phone or IM system which help us to reduce both transport expenses and time. After preparing the tax return our consultants keep you informed about the financial results, Tax Office and Social Security Office (ZUS) bank transfers.

Online accounting

Try our online accounting services and save time — you don’t have to file paper copies of your documents. Our Clients can easily send scanned sale and purchase documents by e-mail. After processing them, all tax evidence documents (ledger, VAT registers, payrolls, tax return forms etc.) are sent to our Client in PDF format. Finally, the Client can print the records and file them to their source documents.

Document storage

Our Clients’ documents are safely stored and archived in our office. If it is required to store the documents in the Client’s office, we only acquire them temporarily for processing and tax return purposes. After finalizing the tax returns all accounting documents are securely returned to the Client. There is also the possibility to process all the accounting documents onsite, upon request. This optional service is available at additional costs.

Documentation is returned to the Client after closing of each fiscal year and presenting the annual statement.

Safety guarantee

Our office shall be solely and exclusively responsible for the reliability and accuracy of kept books and Clients’ financial statements filed to Tax Office and Social Security Office (ZUS). In the event of a Revenue Office audit of an establishment supported by J&J Tax House, our representative will act on behalf of the Client before the Tax Office and Social Security Office (ZUS). Our Client will be updated about the processing, termination and final results of Revenue Office verification.
