Independent consultants across state lines
Bookkeeping for New Jersey consultants with New York clients
Many New Jersey consultants sell to clients across the river. The books should show who paid you, for what, and where the work was done, because that is what your tax professional will ask.
Invoices, payments and 1099s
Clients send 1099-NEC forms in January. We match them to your invoices and deposits during the year, so there are no surprises when the forms arrive. We also keep a clean record of every client, project and payment.
Record where the work happens
When you work for clients in more than one state, your tax professional may need to know where the work was performed. We help you keep a simple log by client or project, so that information is ready when you need it. We do not give advice on which state taxes what.
Pay yourself on a plan
Without an employer, there is no withholding. We help you set aside money from each payment for estimated taxes and show you a monthly number for what you can safely take home.

FAQ
Common questions
Do you give advice on which state taxes my income?
No. Where you owe tax depends on your facts, and that is a question for a tax professional. We keep the records that answer it.
Can you handle several clients and many invoices?
Yes. We set up customer tracking so you can see who has paid and who has not.
Can you help me get a mortgage as a self-employed person?
We can prepare clean financials and a year of reconciled books, which lenders ask for. See our page on self-employed books for a mortgage.
