Why Outsource Sales Tax Solutions?

There comes a time in the lifecycle of every growing business when the owners question whether it would be better to outsource some tasks rather than doing them themselves. When you started your business, you may have worn all the hats. But today, that may no longer make sense for your company. As you grow, your e-commerce sales and use tax liabilities grow too, and they must be paid in full and on time. That’s where SalesTaxSolutions.US comes in. Our sales tax firm helps small e-commerce businesses with sales tax solutions, including sales tax returns, compliance reviews, audits, business registration and economic nexus determination.

Sales Tax Compliance Outsourcing Saves Time

If you are at all familiar with economic nexus determinations, you know how complicated they can be. Each state has its own individual nexus threshold as well as its own tax rate. Additionally, cities, townships and counties may have their own rules. The District of Columbia and Puerto Rico also have separate regulations.

As a business owner, you are responsible for keeping up to date on all these tax rates, thresholds and any changes these municipalities make to their rules and regulations. As you may imagine, this could be a full-time job in itself. Your time is much more wisely spent producing your goods and growing your business. Leave it to the experts to provide the best sales tax solutions for your business.

Benefits of Outsourcing Sales Tax Preparation

Focus In-house Energies on Business-specific Initiatives

Compliance for Sales Tax on Ecommerce is the monthly treadmill that continues on in eternity. It can take up to two weeks of your in-house staff’s time each month. Without the constant burden of sales tax compliance, in-house management and staff can instead spend their resources and time working on more complicated issues, revenue-generating projects or proactive tax planning – activities that directly contribute to improved bottom-line results.

Streamline The Sales Tax Process

Businesses who have made the transition to outsource sales tax solutions have been shocked at the simplicity and ease of the new process in comparison to performing this function internally. Online businesses can merely provide the data and permit your sales tax consulting firm’s professionals to take it from there. Many of our clientele even take the additional step of setting up remote access, enabling the firm to pull the necessary data on their own. By choosing the right sales tax consulting firm as your partner, your company’s sales tax return filing can shift from a burden to a breeze.

Reduce Costs

Cost regulation is an issue at the forefront of all well-run businesses’ collective minds. Savings can come in a number of forms, like the reduction in staffing and overhead, removal of sales tax compliance training after turnover, and exclusion of payment errors and penalties for late filing. Reduce your business costs by outsourcing your sales tax solutions to experts with decades of experience that can find you additional savings.

Improve Consistency and Accuracy

Returns will be filed accurately with all the right figures getting into all the correct fields on every return. Has the tax rate for the jurisdiction you follow been changed? That’s one less problem you’ll have! Your sales tax compliance partner needs to provide you with a clear audit trail including easy and quick access to all sales tax returns, payment vouchers, backup work papers, and other relevant documents.
