I got married in May 2013. We decided before getting married that we were going to combine our finances, and that we would both change our info and file together. Does it matter who the primary taxpayer is on the claim? Is he always first or does it go by higher earner?
You can make your own choice regarding who is the "primary" taxpayer and who is "spouse" on your first Married Filing Joint tax return together, but it's important to note that you need to file all future joint returns the same, no matter who made more money or even didn't have any income at all during a future tax year.
