Why good tax starts with the books

The foundation

A return is only as good as the books under it. When the year is kept current, tax season becomes a summary of numbers you already know. When it is not, tax season is where you find out what went wrong.

When Excello keeps your books, every month closes within five business days, so the year is finished before the first deadline arrives and each return starts from reconciled figures.

It is the same idea behind why Excello exists: people who excel at their work deserve to know exactly where their business stands. That should include the tax bill, well before it is due.

Tax season should never be the first time you find out what your business earned.

When your company and your founders are in different countries

Across borders

Many startups are founded in one country and incorporated in another. Each piece owes its own returns, and they only make sense when they are prepared together.

How to choose a startup tax accountant

A buyer's checklist

The best tax preparation services for startups are the ones that know your countries and work from real books. Ask each provider these five questions.

Questions to ask a startup tax accountant
What to askWhat a good answer sounds like
Who prepares the return, and from what?"An accountant prepares it from your closed, reconciled books, not from a spreadsheet of totals."
Do you know the rules where we operate?Named returns and deadlines for each country you have a company or founders in.
What happens between returns?Books kept current through the year, so the year-end is a summary, not a rebuild.
How is the work priced?A written quote per return or filing, agreed before any work starts.
Can you work with our existing books?"Yes. If they need work first, that catch-up is quoted on its own."

What small business tax services cost

Pricing

Excello prices small business tax services per return or filing, and agrees the quote before any work starts.

What moves the price:

  • Country and company type. A US LLC, a UAE free zone company and a UK limited company each owe different filings.
  • Owners and filings. More members, founders' personal returns or VAT periods mean more to prepare.
  • The state of the books. Books kept by Excello are ready; others may need catch-up work, quoted separately.

Frequently asked questions

What do tax services for startups include?

Tax services for startups prepare the returns a young company owes each year, plus the registrations and filings around them. At Excello that covers company returns, VAT, payroll figures and founders' personal returns in the US, the UAE and the UK.

Do I need a startup tax accountant if my company has no revenue?

Usually yes. A US C corporation files Form 1120 even with no income, a foreign-owned US LLC files Form 5472, and a UK company still files accounts and a confirmation statement. The deadlines apply whether or not the business made money.

Can Excello handle tax in more than one country?

Yes. Excello prepares returns in the United States, the UAE and the United Kingdom, so a founder in Dubai with a US LLC, or a UK founder with a Delaware C corp, can have every return prepared in one place.

Do I need Excello to keep my books to use its tax services?

No. Tax can be taken on its own, and Excello starts from the books you already have. If they need work before a return can be prepared, that catch-up is quoted separately and agreed before it starts.

How much do startup tax accounting services cost?

Excello quotes each return or filing before any work starts. The price depends on the country, the type of company, how many owners and filings there are, and how ready the books are.

What is the difference between a tax advisor for startups and a bookkeeper?

A bookkeeper records the year as it happens. A tax advisor for startups turns that record into the returns the company owes. Excello does both, so the returns are prepared from the same books that are closed monthly.
