1, after the reform of the camp, value-added tax should be paid for construction services. If the payment for the completion of the project is agreed in the contract, the tax shall be paid according to the payment date agreed in the contract.

2. The contract signed now belongs to a new project. If it does not belong to the contractor and the project provided by Party A, the general taxpayer should calculate the output tax of VAT according to the statutory tax rate of 1 1%. For example, 500 *11%= 550,000. The input tax amount of special VAT tickets obtained in engineering operation can be deducted. Taxable amount = output tax-input tax.

3. Upon receipt of the project payment, a special VAT invoice can be issued.

4. The contract stipulates that the price does not include tax. Please discuss with Party A further. The contract amount should be supplemented and the output tax should be 550,000 yuan. Both parties are ordinary taxpayers, and your special VAT ticket can be deducted by Party A.. However, if the supplementary contract is not signed and included in the output tax of 550,000 yuan, the value-added tax will also be calculated for the project funds received by your company, and the tax basis is 500/(1+1%), so your profit will be reduced.

I hope my answer is helpful to you, and I hope to adopt it!
